IP and Reference Design Forum
The LatticeMico8 is an 8-bit microcontroller optimized for Field Programmable Gate Arrays (FPGAs) and Crossover Programmable Logic Device architectures from Lattice. Combining a full 18-bit wide instruction set with 32 General Purpose registers, the LatticeMico8 is a flexible reference design written in Verilog and VHDL suitable for a wide variety of markets, including communications, consumer, computer, medical, industrial, and automotive. The core consumes minimal device resources, less than 200 Look Up Tables (LUTs) in the smallest configuration, while maintaining a broad feature set.
The LatticeMico8 is licensed under a new open intellectual property (IP) core license, the first such license offered by any FPGA supplier. The main benefits of using open source IP are greater flexibility, improved portability, and no cost. This new agreement provides all the benefits of standard open source and allows users to mix proprietary designs with the open source core. Additionally, it allows for the distribution of designs in bitstream or FPGA format without accompanying it with a copy of the license.

LatticeMico8 Development Tools
The LatticeMico8 development tools consist of a LatticeMico8 port of version 4.4.3 of the GNU Compiler Collection (GCC) and version 2.18 of GNU Binary Utilities (binutils - assembler, linker and more). These tools are a collection of command line executables hosted on a Linux/Unix or Cygwin (Linux/Unix terminal emulation for Windows) environment.
The toolchain outputs an executable in the ELF format. A deployment tool converts the ELF format executable into a memory output file (.MEM file) which can be used for simulation or as input into Lattice Diamond or ispLever development tools.

Introduction
LatticeECP3™ devices support high-speed I/O interfaces, including Double Data Rate (DDR) and Single Data
Rate (SDR) interfaces, using the logic built into the Programmable I/O (PIO). SDR applications capture data on one
edge of a clock while DDR interfaces capture data on both the rising and falling edges of the clock, thus doubling
the performance. LatticeECP3 I/Os also have dedicated circuitry that is used along with the DDR I/O to support
DDR, DDR2 and DDR3 SDRAM memory interfaces. Refer to the LatticeECP3 Family Data Sheet for a detailed
description of the I/O logic architecture.
This document discusses how to utilize the capabilities of the LatticeECP3 “E” and “EA” devices to implement both
the high-speed generic DDR interface and the DDR and DDR2 memory interfaces. Refer to the Implementing
DDR/DDR2/DDR3 Memory Interfaces section of this document for more information.
There are some differences in high-speed interface architecture between the LatticeECP3 “EA” and “E” devices.
The implementation differences between the two devices are indicated in the appropriate sections of this document.
This document assumes that version 8.0 of the ispLEVER®
software is used for all interfaces. Please see exceptions under each section if you are using the ispLEVER 7.2 SP2.
Steps to Design a High-Speed DDR Interface:
The following steps must be followed to successfully design a high-speed DDR interface using this document.
• Step 1: Determine the type of interface to implement.
Based on the external interface determine the type of high-speed interface to be built. See the Types of HighSpeed DDR Interfaces section for details.
• Step 2: Use the ispLEVER IPexpress™ tool to build the interface.
Once you have determined the type of interface to be built, use IPexpress to build the interface. See the section
Using IPexpress to Build High-Speed DDR Interfaces.
• Step 3: Understand design rules, clocking requirements for each interface.
Understand the architecture, interface rules and clocking requirements for each of the interfaces. See the HighSpeed DDR Interface Details section for a detailed description of each interface. If multiple interfaces are used in
one device, it is critical to follow these design rules to avoid resource conflicts between interfaces.
• Step 4: Review pinout requirements for clock and data pins for each interface before making pin assignments. It is critical that the interface clock and data pins follow the placement recommendations listed in the section Placement Guidelines for High-Speed DDR Interfaces. If using interfaces requiring DQ-DQS grouping, follow
the rules described in the section DQ-DQS Grouping Rules.
• Step 5: Assign timing preferences and clock preferences.
Follow the guidelines in the section Timing Analysis for High-Speed DDR Interfaces to assign timing preferences
for the interfaces.
• Step 6: Run software Place and Route without DRC and Trace.
It is important that the software Place and Route tool pass without any DRC errors. If it runs into DRC errors
review the sections described above to make sure you are not violating any of the design/pinout rules for the
interface. Run Trace to look at the static timing analysis results for all the timing preferences added to the design.
Make design changes as necessary to assure that you are meeting your timing requirements.

I/O Interface
Steps to Generate a Valid Pinout for a High-Speed DDR Interface:
Due to the various design rules and pinout requirements for each interface, it is critical that the interfaces be created as described above and run through the software before designing the PCB. If it is necessary to determine
pinouts for a PCB design before the complete design is in place, the user must follow the steps listed below to create the pinouts.
• Step 1: Determine the type of interface to implement.
Based on the external interface, determine the type of high-speed interface to be built. See the section Types of
High-Speed DDR Interfaces for details.
• Step 2: Use the ispLEVER IPexpress Tool to build the interface.
Once you have determined the type of interface to be built, IPexpress should be used to build the interface. See
the section Using IPexpress to Build High-Speed DDR Interfaces.
• Step 3: Build the complete I/O ring and clocking structure.
Some dummy logic may be required to assure that the data out of the DDR elements are not optimized out by the
software. For example, if you are building an input and a corresponding output interface you may connect them
using dummy register between the two interfaces. If you are building receive-only interfaces, the signals out of
the receive interface will need to be used in dummy logic or assigned to outputs. Similarly, if building a transmitonly interface you must provide input signals that are used in the transmit interface.
• Step 3: Understand the design rules and clocking requirements for each interface.
Understand the architecture, interface rules and clocking requirements for each of the interfaces. See the HighSpeed DDR Interface Details section for a detailed description of each interface. If multiple interfaces are used in
one device, it is critical to follow these design rules to avoid resource conflicts between interfaces.
• Step 4: Make pin assignments for clock and data pins for each interface following the design and pinout
rules. Assign the input and output pins to specific sites, banks or DQS groups. Review the pinout requirements
for the clock and data pins for each interface before making pin assignments. It is critical that the interface clock
and data pins follow the placement recommendations listed in the section Placement Guidelines for High-Speed
DDR Interfaces. If using interfaces requiring a DQ-DQS grouping, you must follow the rules described in the section DQ-DQS Grouping Rules.
• Step 5: Run the design through ispLEVER Place and Route and pass without any DRC errors.
If you run into errors, change pin assignments as required to pass all the DRC checks. When the design passes
Place and Route, the pin assignments listed in the PAD report can be used on the board.
External Interface Description
This technical note uses two types of external interface definitions, centered and aligned. In a centered external
interface, at the device pins, the clock is centered in the data opening. In an aligned external interface, at the device
pins, the clock and data transition are aligned. This is also sometimes called “edge-on-edge”. Figure 12-1 shows
the external interface waveform for SDR and DDR.12-3
LatticeECP3 High-Speed
I/O Interface
Figure 12-1. External Interface Definition
The interfaces described are referenced as centered or aligned interfaces. An aligned interface is needed to adjust
the clock location to satisfy the capture flip-flop setup and hold times. A centered interface is needed to balance the
clock and data delay to the first flip-flop to maintain the setup and hold already provided.
High-Speed I/O Interface Building Blocks
The LatticeECP3 device contains dedicated functions for building high-speed interfaces. This section describes
when and how to use these functions. A complete description of the library elements including descriptions and
attributes is provided at the end of this document.
Figure 12-2 shows a high-level diagram of the clocking resources available in the “E” and “EA” devices for building
high-speed I/O interfaces.

A complete description and of the LatticeECP3 clocking resources and clocking routing restrictions is available in
TN1178, LatticeECP3 sysCLOCK™ PLL/DLL Design and Usage Guide.
Below is a brief description for each of the major elements used for building various high-speed interfaces. The
DDR Software Primitives and Attributes section describes the library elements for these components.
ECLK
Edge clocks are high-speed, low-skew I/O dedicated clocks. They are arranged in groups of two on the left, right,
and top sides of the device.
SCLK
SCLK refers to the system clock of the design. SCLK can use either primary or secondary clocks.
DQS Lane
A DQS Lane borrows its name from memory interfaces, but can be used for general-purpose high-speed interfaces. Each DQS Lane provides a clock (DQS) and up to 10 data bits on that clock. The number of DQS Lanes on
the device is different for each device size. LatticeECP3 devices support DQS signals on the top, left and right
sides of the device.

LatticeECP3 High-Speed
I/O Interface
PLL
The PLL provides frequency synthesis as well as static and dynamic phase adjustment. Three output ports are provided: CLKOP, CLKOS and CLKOK. CLKOK provides a dedicated divide-by-2 function for use with the I/O logic
gearing. The number of PLLs available on the device varies by device size from 2 to 10 PLLs per device.
DLL
The general-purpose DLL provides clock injection delay removal as well as 90° delay compensation when used
with the DLLDEL element. There are two DLLs, one on each side of all LatticeECP3 devices.
DQSDLL
The DQSDLL is a dedicated DLL for creating a 90° clock delay. There are two DQSDLLs provided on all
LatticeECP3 devices. There is one DQSDLL on each side of the device.
Input DDR (IDDR)
The input DDR function can be used in either x1 or x2 gearing modes. The x1 mode is supported by the IDDRXD
element. This library element inputs a single DDR data input and clock (DQS, ECLK or SCLK) and provides a 2-bit
wide data synchronized to the SCLK (system clock) to the FPGA fabric.
In the x2 mode, the IDDRX2D element is used. This element is useful for interfaces with greater than a 200MHz
clock. It supports a 4-bit wide interface to the FPGA fabric. The clock input to the IDDRX2D is the high-speed
ECLK. The SCLK clock is divided down to half of the ECLK input clock.
Output DDR (ODDR)
The output DDR function can also be supported in either x1 or x2 gearing modes. The output x1 DDR function is
supported by the ODDRXD element. This library element provides a single DDR output and clock (SCLK) and
accepts 2-bit wide data from the FPGA fabric.
The ODDR2XD element is used in the x2 mode and supports a 4-bit wide interface to the FPGA fabric. This element is useful for interfaces with greater than a 200MHz clock. The SCLK clock is divided down to half of the ECLK.
CLKDIV
The CLKDIV element is used to divide the high-speed ECLK by 2 to generate the SCLK when using x2 input or output gearing modes.
DELAY
There are three types of input data available. DELAYC provides a fixed value of delay to compensate for clock
injection delay. DELAYC is used by default when configuring the interface in the software. Software will configure
the DELAYC with delay values based on the interface used. DELAYB provides dynamic or user-defined delay.
DELAYC is also used for SDR interfaces where it provides clock injection delay.
ECLK/SCLK vs. DQS Lanes
ECLK and SCLK span the entire side of the device and is useful for creating wide input bus interfaces. The DQS
Lanes cover only 10 bits of data width and work well for narrow input bus interfaces. Each DQS Lane is serviced by
a DQSBUF to control clock access and delay. The DQS Lane is supported by the DQSDLL for 90° clock delay.
There is only one DQSDLL per side of the device, but this DQSDLL can be used for all of the DQS Lanes on the
side. If several narrow input bus interfaces are required it is best to use the DQS Lanes instead of the ECLK or
SCLK.
Due to architectural difference between “E” and “EA” devices, wider buses are supported using ECLK in “E”
devices and SCLK in “EA” devices in x1 mode.12-6

Receive Interfaces
This section lists the receive interfaces can be implemented.
1. Single Date Rate Interface (GIREG_RX.SCLK)
This interface is used when a simple input register is required for the design. The clock input to the input
register can be optionally inverted if required. These interfaces always use SCLK.
2. Input DDR 1x Interfaces
Input DDR 1x interfaces are used for DDR interfaces running at or below 200MHz. The 1x interfaces can
be further split into aligned and centered interfaces depending on the incoming clock-to-data relationship.
In addition, for each of these interfaces the incoming data is delayed using the DELAYC element to compensate for the clock injection time.
a. Aligned Interfaces
These interfaces are used when the data and clock are aligned edge-on-edge when input to the
device. The clock on the aligned interfaces is phase-shifted 90° using the on-chip DLL or DQSLL on
each side of the device. These interfaces are further split into the following interfaces.
i. Input DDR 1x Aligned Interface using SCLK (GDDRX1_RX.SCLK.Aligned/
GDDRX1_RX.SCLK.PLL.Aligned)
This interface is used on “EA” devices when the clock and data are aligned edge-on-edge.
The clock is shifted 90° using a DLL or PLL before it is used in the IDDRX1 element. The
SCLK is used in this case to clock the IDDRX1 element on the “EA” device.
ii. Input DDR 1x Aligned Interface using ECLK (GDDRX1_RX.ECLK.Aligned)
This interface is used on “E” devices when the clock and data are aligned edge-on-edge
when coming into the device. ECLK is used to clock the IDDRX1 element on the “E” device.
This clock is shifted 90° using DLL before it is routed to the ECLK.
iii. Input DDR 1x Aligned Interface using DQS (GDDRX1_RX.DQS.Aligned)
This interface is used when the interface bus is narrow (<10 bits) and the clock and data
are aligned edge-on-edge. In this case, the DQS Lanes are used for each interface and the
DQS pin is used for the clock input. The 90° shift for the clock is generated using the DQSDLL and the clock is delayed in the DQSBUF element. This delayed clock is used to clock
the IDDRX1 element. This interface then uses SCLK to clock the data from the interface to
the FPGA logic.12-8
LatticeECP3 High-Speed
I/O Interface
b. Centered Interfaces
These interfaces are used when the data and clock are centered when input to the device. Since
the clock is centered to the data, it is not required to be phase-shifted for these interfaces. These
interfaces are further split into the following interfaces.
i. Input DDR 1x Centered Interface Using ECLK (GDDRX1_RX.ECLK.Centered)
This interface is used on “E” devices when the clock and data are centered coming into the
device. The ECLK is used to clock the input DDR element on the “E” device.
ii. Input DDR 1x Centered Interface Using SCLK (GDDRX1_RX.SCLK.Centered)
This interface is used on “EA” devices when the clock and data are centered coming into
the device. The SCLK is used to clock the input DDR element on the “EA” device.
iii. Input DDR 1x Centered Interface using DQS (GDDRX1_RX.DQS.Centered)
This interface is used when the interface bus is narrow (<10 bits) and the clock and data
are centered. In this case, the DQS Lanes are used for each interface and the DQS pin is
used for the clock input. DQSDLL is held in reset for this case as no clock shift is required.
This interface then uses SCLK to clock the data from the interface to the FPGA logic.
3. Input DDR 2x Interfaces
Input DDR 2x interfaces are used for DDR interfaces running higher than 200MHz. The 2x interfaces can
be further split into aligned and centered interfaces depending on the incoming clock-to-data relationship.
In addition, for each of these interfaces the incoming data is delayed using DELAYC element to compensate for the clock injection time.
a. Aligned Interfaces
These interfaces are used when the data and clock are aligned edge-on-edge when input to the
device. The clock on the aligned interfaces is phase shifted 90° using the on-chip DLL or DQSLL on
each side of the device. These interfaces are further split into the following interfaces.
i. Input DDR 2x Aligned Interface using ECLK (GDDRX2_RX.ECLK.Aligned/
GDDRX2_RX.ECLK.Aligned (No CLKDIV))
This interface is used when the clock and data are aligned edge-on-edge. The incoming
clock is shifted 90° using the DLL. The output of the DLL is routed to the ECLK which is
used to clock the IDDRX2 element.The SCLK required for this interface is generated by
dividing the ECLK by two in the CLKDIV module or in the DLL module.
ii. Input DDR 2x Aligned Interface using DQS (GDDRX2_RX.DQS.Aligned)
This interface is used when the interface bus is narrow (<10 bits) and the clock and data
are aligned edge-on-edge. In this case, the DQS Lanes are used for each interface and
DQS pin is used for the clock input. The 90° shift for clock is generated using the DQSDLL
and the clock is delayed in the DQSBUF element. This delayed clock is used to clock the
IDDRX2 element. The SCLK required for this interface is generated by dividing the ECLK
by two in the CLKDIV module.
b. Centered Interfaces
These interfaces are used when the data and clock are centered when input to the device. Since
the clock is centered to the data, it does not required to be phase-shifted for these interfaces. These
interfaces are further split into the following interfaces.
i. Input DDR 2x Centered Interface using ECLK (GDDRX2_RX.ECLK.Centered)
This interface is used when clock and data are centered coming into the device. The clock
is connected directly to the ECLK which is used to clock the IDDRX2 element. The SCLK
required for this interface is generated by dividing the ECLK by two in the CLKDIV module.12-9
LatticeECP3 High-Speed
I/O Interface
ii. Input DDR 1x Centered Interface using DQS (GDDRX2_RX.DQS.Centered)
This interface is used when the interface bus is narrow (<10 bits) and the clock and data
are centered. In this case, the DQS Lanes are used for each interface and the DQS pin is
used for the clock input going to the DQSBUF module. DQSDLL is held in reset for this
case as no clock shift is required. The clock output of the DQSBUF is used to clock the
IDDRX2 element. A PLL is used to generate the SCLK for this interface.
c. Dynamic Interfaces (“EA” Devices Only)
The data delay input on the data input of the input DDR 2x centered interfaces can optionally be
controlled dynamically by the user logic using the DELAYB element. For dynamic control of the
clock or data delay, one of following dynamic interfaces can be used. The dynamic interfaces are
only available on “EA” devices.
i. Input DDR 2x Centered Interface Using ECLK and Dynamic Delay
(GDDRX2_RX.ECLK.Dynamic)
This interface is similar to the GDDRX2_RX.ECLK.Centered interface described above but
the input data delay is controlled by the user with the DELAYB element.
ii. Input DDR 2x Centered Interface Using DQS and Dynamic Delay
(GDDRX2_RX.DQS.Dynamic)
This interface is similar to the GDDRX2_RX.DQS.Centered interface described above but
the input data delay is controlled by the user with the DELAYB element.
iii. Input DDR 2x Centered Interface Using PLL and Dynamic Delay
(GDDRX2_RX.PLL.Dynamic)
In this interface the PLL is used to dynamically shift the clock to adjust to the correct position to the data. This interface will generate a bus-based delay for the interface.
d. 7:1 LVDS Interface
This interface should be used when implementing a 7:1 LVDS interface. The 7:1 LVDS interface
requires that the input clock is multiplied 3.5x before input to the IDDRX2 element to demux the
data. Refer to RD1030, 7:1 LVDS Video Interface Reference Design for further information.
Transmit Interfaces
This section lists the transmit interfaces can be implemented.
1. Single Date Rate Interface (GOREG_TX.SCLK)
This interface is used for a SDR data output implementation with tight specifications on clock out to data
out skew. This interface uses a simple output flip-flop for the data but forwards the clock using an ODDRX
register. The same clock is used for both data and clock generation.
2. Output DDR 1x Interfaces
Output DDR 1x interfaces are used for DDR interfaces running at or below 200MHz. The 1x interfaces can
further be spilt into aligned and centered interfaces depending on the relationship between the forwarded
clock and data. The following are the different 1x interfaces.
a. Aligned Interfaces
These interfaces are used to provide data and clocks that are aligned edge-on-edge when leaving
the device. These interfaces are further split into the following.

This interface uses SCLK to generate clock and data that are aligned edge on edge
b. Centered Interfaces
These interfaces are used to provide data and clocks that are centered when leaving the device.
The clock output is phase-shifted 90° using the on-chip PLL so that it can be centered to the data.
These interfaces are further split as follows.12-10
LatticeECP3 High-Speed
I/O Interface
i. Output DDR 1x Centered Interface Using SCLK (GDDRX1_TX.SCLK.Centered)
In this case, the SCLK is used to generate the data and clock output. SCLK used to generate the clock is shifted 90° using a PLL so that it can be pre-centered to the data output.
ii. Output DDR 1x Centered Interface Using DQS (GDDRX1_TX.DQS.Centered)
This interface is used when implementing interfaces that are <10 bits wide. The DQS
Lanes are for data and clock assignments. The clock is pre-centered to the data using the
DQSLL and the ODDRDQSA blocks.
3. Output DDR 2x Interfaces
Output DDR 2x interfaces are used for DDR interfaces running higher than 200MHz. The 2x interfaces can
further be spilt into aligned and centered interfaces depending on the relationship between the forwarded
clock and data. Output DDR 2x interfaces are supported only on “EA” devices. The following are the different 2x interfaces.

further split into the following.
i. Output DDR 2x Centered Interface using DQSDLL (GDDRX2_TX.DQSDLL.Centered)
This interface is primarily used for interfaces that are <10 bits wide. In this case, a DQSDLL
is used to generate the 90° shift required to pre-center the clock to the data output.
ii Output DDR 2x Centered Interface using PLL (GDDRX2_TX.PLL.Centered)
This interface is primarily used for wider interfaces. Here, a PLL is used to generate the 90°
shift required to pre-center the clock to the data output.
c. 7:1 LVDS Interface
This interface is used when implementing a 7:1 LVDS interface. The 7:1 LVDS interface requires
that the clock output be multiplied 3.5x before going to the ODDRX2 module. Refer to RD1030, 7:1
LVDS Video Interface Reference Design for further information.
Using IPexpress to Build High-Speed DDR Interfaces
The IPexpress tool is used to configure and generate all the high-speed interfaces described above. IPexpress
generates a complete HDL module including clocking requirements for each of the interfaces.
This section assumes that ispLEVER 8.0 is used for generation of the interfaces. If you are using ispLEVER 7.2
SP2, see Appendix A. Building DDR Interfaces Using IPexpress in ispLEVER 7.2 SP2. If you are using Lattice Diamond®
design software, see Appendix B. Building SDR/DDR Interfaces Using IPexpress in Diamond.
For a detailed block diagram of each interface generated by IPexpress, see the High-Speed DDR Interface Details
section.
IPexpress can be opened from the Tools menu in Project Navigator. All DDR modules are located under Architecture Modules -> IO. This section will cover SDR and DDR_GENERIC. DDR_MEM is discussed in the Implementing DDR/DDR2/DDR3 Memory Interfaces section.12-11

Table 12-5 shows how the interfaces are selected by IPexpress based on the selections made in the Pre-Configuration Tab.
The implementation for several of the interfaces described above differs between the “E” and “EA” devices. Refer to
the High-Speed DDR Interface Details section to see implementation details for “E” and “EA” devices.
The Data Delay setting for each interface is predetermined and cannot be changed by the user. User can only control Data Delay values when using a dynamic interface.
Note: Some modules generated by IPexpress have a SCLK and ECLK output port. If present, this port must be
used to drive logic outside the interface driven by the same signal. In these modules, the input buffer for the clock is
inside the IPexpress module and therefore cannot be used to drive other logic in the top level.
High-Speed DDR Interface Details
This section describes each of the generic high-speed interfaces in detail including the clocking to be used for each
interface. For detailed information about the LatticeECP3 clocking structure, refer to TN1178, LatticeECP3 sysCLOCK PLL/DLL Design and Usage Guide. The various interface rules and preferences listed under each interface
should be followed to build these interfaces successfully. Each of the interfaces for the “EA” devices has an ID label
associated with the interface. The interface ID will be set when generating the interface using IPexpress. This ID is
entered using an attribute called IDDRAPPS or ODDRAPPS. The software uses this ID to set appropriate the data
delay for the DELAYC element used in each of the interfaces. It is required that every interface on the “EA” devices
use this attribute to achieve the correct timing results in the software Trace report. Refer to the Timing Analysis for
High-Speed DDR Interfaces section for more information about the timing analysis on these interfaces. It is also
necessary to follow the interface rules and preferences listed for each of the interface descriptions below for the
interfaces to work as described.

GIREG_RX.SCLK
Generic SDR Receive Interface using SCLK.
Device Support: “E” and “EA” devices
Description
This is a generic interface for single data rate (SDR) data. An optional inverter can be used to center the clock for
aligned inputs. A PLL or DLL can be used to remove the clock injection delay or adjust the setup and hold times.
There are a limited number of DLLs in the architecture and these should be saved for high-speed interfaces when
necessary. This interface can either be built using IPexpress or inferred during synthesis.
Figure 12-8. GIREG_RX Interface (“E” and “EA” Devices)
This interface also supports data delay on the data input. This delay value is set using a DELAYB or a DELAYC element. A DELAYC element provides a fixed delay to match the SCLK injection time.
DELAYB is used when user chooses to update the delay dynamically or use user-defined static values. Figure 12-
9 shows the DELAYB element connected to this interface.

GDDRX1_RX.ECLK.Aligned
Generic DDR Receive Interface using ECLK with Aligned External Interface
Device Support: “E” devices only
Description
This DDR interface uses the ECLK and the TRDLLB to provide a 90° clock shift to center the clock at the IDDRXD.
DLLDELB is used to delay the incoming clock by 90°. CLKDIV is used to generate a divide-by-1 clock that is connected to the SCLK. Since this interface uses the ECLK it can be extended to support large data bus sizes for the
entire side of the device.
Figure 12-10. GDDRX1_RX.ECLK.Aligned Interface (“E” Devices Only)
Interface Rules
• The input clock must use a GPLLT_IN or GDLLT_IN pin. All data for the interface must all be on the same ECLK
(same side).
• Since there is only one DLLDELB and one CLKDIVB per left and right sides of the device, users can implement
only one such interface per side, or two total on the device.
• The clock net connected to SCLK should be on a primary clock net. The user must assign the “USE PRIMARY
NET” preference to assign the SCLK clock net to a primary clock.
• The pin assignments for data and clocks will require following the DQ-DQS lane assignments. Refer to the
Generic DDR Design Guidelines section for details.

Description
This DDR interface uses the DQS and the DQSDLL to provide a 90° clock shift to center the clock at the IDDRXD.
This interface is uses a DQS lane and is useful for small data buses (< 11 bits). DQSDLL provide the 90° delay to
the DQSBUFF which is used to delay the incoming clock.

Interface Rules
• The input clock must use a DQS input pin and all data inputs must be in the same DQS lane.
• The VREF1 for the selected DQS lane must be powered on the board.
• There is only one DQSDLL per side of the device which limits sharing of this interface on a side unless all are
running at the same rate.
• The following sequence must be followed when resetting the interface:
– Assert DQSDLL_RESET to DQSDLL and RESET to the modules
– Deassert DQSDLL_RESET to DQSDLL first
– Wait for DQSDLL lock to go high
– Assert DQSDLL_UDDCNTLN input of DQSDLL for at least four SCLK cycles. See the section “DQSDLLB”
on page 89 for the detailed requirements for the DQSDLL_UDDCNTLN input of DQSDLLB
– Deassert DQSDLL_UDDCNTLN
– Wait for four SCLK cycles, then deassert RESET to the other modules
• “dqsdll_clk” and clock net connected to SCLK must use the primary clock tree. It is the user’s responsibility to
assign the “USE PRIMARY NET” preference on these nets to assign it to the primary clock.
• The pin assignments for data and clock will require following the DQ-DQS lane assignments. Refer to the

Generic DDR Receive Interface with x2 Gearing using a DQS lane with Aligned External Interface
Device Support: “E” and “EA” devices
Description
This DDR x2 interface uses the DQS and the DQSDLL to provide a 90° clock shift to center the clock at the
IDDRXD. This interface uses a DQS lane and is useful for small data buses (<11 bits). There is only one DQSDLL
per side of the device which limits sharing of this interface on a side unless all are running at the same rate.
This interface uses x2 gearing with the IDDRX2D element. This requires the use of a CLKDIVB to provide the
SCLK which is half the frequency of the ECLK and ECLKDQSR.
This interface requires the use of a secondary input pll_clk for the PLL input. The PLL output must run at the same
rate as the DQSI clk input, but can be arbitrary phase.

GDDRX2_RX.DQS.Centered
Generic DDR Receive Interface with x2 Gearing using a DQS lane with Centered External Interface
Device Support: “E” and “EA” devices
Description
This DDR x2 interface uses the DQS and DELAYC to match clock and data delay at the IDDRX2D. This interface is
useful for small data buses (<11 bits). Since a 90° shift is not required, the DQSDLL is held in reset for this interface. An additional refclk input running at the same as the clk input to DQSI is provided to the DQSDLL, ECLK input
of the IDDRX2D. It is also used in the CLKDIV module to generate the SCLK which is half the frequency as the
input clock.12-30

Notes:
1. The DELAYC is only applicable for “EA” devices. For “E” devices, change DELAYC to DELAYB and set the value to 7.
2. When retargeting from “E” to “EA”, manually update DELYAB to DELAYC, otherwise the software will error out.
Interface Rules
• The input clock must use a DQS input pin and all data inputs must be in the same DQS lane.
• The ECLK clock input must use a dedicated GPLLT_IN input or PCLK input pin or from a primary clock tree. This
second synchronous clock input is used for the DQSDLL, ECLK, and CLKDIV.
• There is only one DLLDELB and one CLKDIV per side of the device (left and right sides) which limits this interface to one clock rate per side or two per device.
• The clock net connected to SCLK must be routed on a primary routing resource using the “USE PRIMARY
NET” preference.
• The pin assignments for data and clock will require following the DQ-DQS lane assignments. Refer to the

Generic SDR Transmit Interface using SCLK
Device Support: “E” and “EA” devices
Description
This is a generic interface for SDR data and a forwarded clock. The ODDR used for the clock balances the clock
path to match the data path. A PLL can also be used to clock the ODDRXD to phase shift the clock to provide a
precise clock-to-data output.
On “E” devices, the sides (left and right) need to pass through a DQSBUFG before going to the ODDRXD element.
The top does not require the DQSBUFG and can take SCLK directly.
The “EA” device does not require a DQSBUFG block.

7:1 LVDS Implementation
It is recommended that the 7:1 LVDS Video Interface Reference Design provided on the lattice web site be used to
implement all 7:1 LVDS designs.
Generic DDR Design Guidelines
This section describes the various design guidelines used for building generic high-speed DDR interfaces in
LatticeECP3 FPGAs. In additional to these guidelines, it is also necessary to follow the interface rules for each
interface type as described above.
Placement Guidelines for High-Speed DDR Interfaces
The following clock and data placement guidelines should be followed for high-speed design requirements. The
software will place the clock and data as specified by the user, but in order to achieve higher speeds the user must
follow the placement rules listed in Table 12-6 for each interface type.
It is required that all clocks used to clock the DDR Interfaces use a dedicated clock path. No general routing should
be used to route the clock pin. General routing used for a clock path will cause duty cycle distortion as well as limit
the operational frequency of the interface. It is the responsibility of the user to assign clock inputs to dedicated
clock pins and use preferences such as “USE PRIMARY NET” to route clock nets on dedicated clock paths.
Table 12-6 lists the various high-speed interfaces and the placement required for the clock and data.

High-Speed Clock Bridge (“EA” Devices)
The high-speed clock bridge is available only on “EA” devices on the GDDRX2.RX.PLL_Dynamic interface. The
bridge enables a clock to route to a single edge clock or multiple edge clocks on the device using a three-way
(left/right/top) bridge. It can only be used on clocks coming in from the left side dedicated GPLLT pin or PLL output.
The software preference EDGE2EDGE is used to enable this route.
For example, USE EDGE2EDGE ; where “pllin_c” is the clock net coming from the dedicated GPLLT pin.
When this preference is placed on the clock coming in on the left side GPLLT pin, this clock will be connected to the
one of the ECLK on the left, right and top sides using a dedicated route. This ECLK on all three sides cannot be
used for any other ECLK function. User will have to make the following changes to the GDDRX2.RX.PLL_Dynamic
module generated by IPExpress to incorporate the ECLKBRIDGE.
• A CLKDIV should be used to generate SCLK instead of using PLL CLKOK. The CLKOS output of the PLL should
be connected to the input of the CLKDIV module. Output of CLKDIV is used as SCLK.
• User will have to instantiate 2 ECLKSYNC modules to be used on either side of the device. Both of them should
be connected to the CLKOS of the PLL used as ECLK.
• An EDGE2EDGE preference should be assigned to the CLKOS output of the PLL to be used as ECLKBRIDGE.
DQ-DQS Grouping Rules
Due to differences in architecture between the LatticeECP3 “E” and “EA” devices, the DQ-DQS grouping that is
required for some interfaces in “E” devices is not required for “EA” devices. It is necessary to use the DQS grouping
structure to group pins when either of the DQSBUFE/DQSBUFF/DQSBUFG modules is used in an interface. Refer
to the section High-Speed DDR Interface Details to see the requirements for each device.
Below are some of the rules to be followed when locking DQS groups. ispLEVER will check for these rules during
MAP and Place and Route.
• Each DQS pin has a DQSBUF block which spans across 12 pins including the DQS and DQS# pins. Each DQSBUF sends out control logic to these pins.
• The DQS# I/O logic registers cannot be used to implement DDR registers. DQS pins can be used for IDDR
implementation only. ODDR cannot be assigned to a DQS pin.

I/O Interface
• The DQS and DQS# I/O logic registers can be used to implement SDR input and output registers. If the DQSBUF of that DQS group is used then it cannot be used for SDR functions unless the same clock going to the
DQSBUF is used to clock the SDR register at the DQS/DQS# site.
• An IDDRX element used for a generic DDR interface cannot be mixed in a DQS group with an ODDRX element
used for implementing a DDR memory interface.
• Similarly, an ODDRX element used for a generic DDR interface cannot be mixed in a DQS group with an IDDRX
element used for a DDR memory interface.
• The ODDRXD and ODDRX2D elements in a given DQS group cannot share the same DQSBUF and therefore
cannot be placed together within the same DQS group.
• The upper left corner of the LatticeECP3 device has a DQS group without a DQS pin. This group of I/Os does not
have a DQS function. It is recommended to use this group for pins in non-DQS interfaces.
• See Table 12-13 to see the availability on each side.
I/O Logic (IOL) Site Types/Names
Based on the functions they support, I/O logic blocks are divided into the following site types.
• IOLOGIC – This site supports IREG, OREG, IDDRX, IDDRX2, ODDRX and ODDRX2 functions. These are the
IOLs on the left and right sides of the device.
• SIOLOGIC – This site supports IREG, OREG, IDDRX, IDDRX2 and ODDRX functions. There is no ODDRX2
support in this site. These are mainly the IOLs on the top side of the device.
• XSIOLOGIC – This site supports IREG and OREG only. These are primarily the bottom side IOLs and DQS#
IOLs.
• DQSIOL – These are the DQS IOLs. They support IREG, OREG, IDDRXD, IDDRX2, ODDRXDQSA and
ODDRX2DQSA (left and right sides only) functions
• SDQSIOL – These are DQS IOLs with support for IREG, OREG and DQS ODDRXDQSA functions. Compared
to DQSIOL, there is no ODDRX2DQSA support in this site. These are mostly the DQS IOLs on the top side of
the device.
The software will issue an error message using these site names when an unsupported function is placed on one
of these sites.12-46

Design Rules for Fitting Multiple Interfaces into One Device
Rx Interfaces Running at High Speeds (>250 MHz)
Receive interfaces running at speeds higher than 250 MHz must use the x2 mode gearing DDR elements.
• To achieve high speeds these interfaces must be placed on the left and right sides of the device.
• If implementing a centered interface then the clock input must be locked to a primary clock (PCLK) input pin
• If implementing an aligned interface then the clock input must be locked to a dedicated GPLLT if interface is
using a PLL GDLLT input pin if interface is using a DLL.
• Interfaces using the x2 gearing will need to use the edge clock resource. A single edge clock covers only one
side of the device, hence all the data bits in the data bus should be assigned to one side of the device.
• There are two edge clocks per side. Two interfaces can be implemented per side of the device as long as they
both do not require the DLL or CLKDIV module. See below:
– There is only one CLKDIV and one DLL module available per side, hence two interfaces that use the CLKDIV and/or the DLL module cannot be on the same side.
– When implementing an aligned interface using the DLL module (GDDRX2_RX.ECLK.Aligned) only one
interface can be implemented per side as there is only one DLL and one CLKDIV per side of the device.
– When implementing an aligned interface using a PLL (GDDRX2_RX.PLL.Dynamic), up to two of these interfaces can be implemented per side. It is recommended to allow the software to choose the best clock pins
after locking the data inputs to the desired banks.
– You can mix an aligned interface using a PLL (GDDRX2_RX.PLL.Dynamic) and a centered interface
(GDDRX2_RX.ECLK.Centered) on the same side of the device. It is recommended to allow the software to
choose the best clock pins after locking the data inputs to the desired banks.
– You can mix an aligned interface using a DLL (GDDRX2_RX.ECLK.Aligned) and a centered interface
(GDDRX2_RX.ECLK.Centered) on the same side of the device. It is recommended to allow the software to
choose the best clock pins after locking the data inputs to the desired banks.
– A GDDRX2_RX.ECLK.Aligned and GDDRX2_RX.PLL.Dynamic can be implemented on the same side of
the device. In this case, the clock going to the PLL must be locked to a dedicated PLL clock input pin in the
center of the device close to the DLL pin. For example, if the DLL pin is placed on the LUM0_GDLLT_IN_A
pin then the clock input to the PLL must be placed on the LUM0_GPLLT_IN_A pin. It is recommended to
allow the software to pick the best clock pins after locking the data inputs to the desired banks
– For all interfaces using PLLs, refer to TN1178, LatticeECP3 sysCLOCK PLL/DLL Design and Usage Guide
to see which two dedicated PLL clock outputs can feed the ECLK tree
• When multiple receive interfaces with multiple input clocks are required, and if the data widths for each of these
interfaces is <10 bits wide, then the DQS clock can be used to implement these interfaces
(GDDRX2_RX.DQS.Aligned and GDDRX2_RX.DQS.Centered)
– For these interfaces it is required to connect the input clock to the DQS input pin
– Data bits of the bus must be locked to the corresponding data pins
– See the section “DQ-DQS Grouping Rules” for pin assignment rules.
Rx Interfaces Running at Low Speeds (<250 MHz)
• Receive interfaces running at speeds lower than 250 MHz can use the x1 mode gearing DDR elements.
• If implementing a centered interface then the clock input must be locked to a primary clock (PCLK) input pin
• If implementing an aligned interface then the clock input must be locked to a dedicated “GPLLT” if interface is
using a PLL “GDLLT” input pin if interface is using a DLL.
• Interfaces using the x1 gearing will use the primary clock resource. You can use as many interfaces as the number of primary clocks supported in the device.
– If all interfaces are aligned and using a GDDRX1_RX.SCLK.Aligned interface that uses a DLL, then the
number of interfaces is limited to two as there are two DLLs supported per device.
– If using a GDDRX1_RX.SCLK.PLL.Aligned interface then the number of interfaces per device is limited by
the number of PLLs available in that device.12-48
LatticeECP3 High-Speed
I/O Interface
Tx Interface Running at High Speeds (> 250 MHz)
• Transmit Interfaces running at speeds higher than 250 MHz must use the x2 mode gearing DDR elements.
• To achieve high speeds these interfaces must be placed on the left and right sides of the device.
• Both edge clock and DQS clocks are used to implement the transmit side interfaces
• Data pins must be grouped into the DQS groups on these interfaces
• For interfaces requiring True LVDS outputs, the number of available True LVDS pins per DQS group must be calculated from the data sheet pinout tables since only a limited number of pins support True LVDS outputs. It may
be required to modify the HDL generated from IPexpress to reduce the number of pins assigned to each DQS
group
• All transmit interfaces using the x2 gearing mode use the CLKDIV module, hence only one TX interface can be
implemented per side of the device.
• Inputs to the PLL used in the interface should be on primary clock routing or come in from a dedicated GPLLT
input pin
Tx Interface Running at High Speeds (<250 MHz)
• Transmit interfaces running at speeds lower than 250 MHz can use the x1 mode gearing DDR elements
• Interfaces using the x1 gearing will use the primary clock resource. You can as many interfaces as the number of
primary clocks supported in the device.
• If all interfaces are centered, then the number of interfaces will depend on the number of available PLLs on the
device.
Clocking Guidelines for Generic DDR Interfaces
• Edge clock and primary clock resources are used when implementing a x2 receive or transmit interface
• Only the primary clock (PCLK) resources are used when implementing x1 receive or transmit interfaces
• Each edge clock can only span one side of the device, hence all the data bits of the in the x2 interface must be
locked to one side of the device
• When implementing x1 interfaces, the bus can span any two sides as primary clocks can access DDR registers
on all sides
• There are two edge clocks on each left, right of top side of the device. The bottom side does not support DDR
registers and does not have any edge clocks. There are up to eight primary clocks available on a LatticeECP3
device.
• For high-speed interfaces it is recommended to use the edge clocks on the left and right sides of the device
instead of the top side
• See Design Rules for Fitting Multiple Interfaces into One Device for details on implementing multiple interfaces
on one side of a device
• The ECLK to DDR registers can be accessed through dedicated PCLK pins, GPLL outputs, DLL outputs, and
GPLL input pins. See “LatticeECP3 sysCLOCK PLL/DLL Design & Usage Guide” for details
• Primary clock to DDR registers can be accessed through dedicated PCLK pins, GPLL outputs, DLL outputs &
CLKDIV outputs. See “LatticeECP3 sysCLOCK PLL/DLL Design & Usage Guide” for details
• None of the clocks going to the DDR registers can come from internal general routing.
• DQS clocking is mainly used for DDR memory interface implementation.
• The DQS clock spans every 12 I/O’s include the DQS pins, but only 10 of these can be used for generic DDR
implementation12-49
LatticeECP3 High-Speed
I/O Interface
• DQS clocking can also be used for Generic DDR Receive interfaces when the bus size is 10 or less
• DQS clocking is also used when implementing all Generic DDR x2 Transmit interfaces
• Refer to the “DQ-DQS Grouping Rule” section for pinout assignment rules when using DQS clocking
Common Software Errors and Solutions
• Placement error when implementing Transmit high speed True LVDS interface:
“ERROR - par: DDR assignment finished unsuccessfully.”
DQS grouping is used when implementing 2x gearing on the transmit side. This error occurs then there aren’t
enough true LVDS buffers in one DQS group. IPexpress generates DQS groups correctly for emulated buffers.
Since the number of true LVDS pins vary per device and package, users need to update the module generated
by IPexpress to correct the number of pins per DQS group.
• PAR Routing error when not using dedicated clock routing:
“ERROR - par: netsanitycheck: the clock buf_clk on comp Inst4_DLLDELB port CLKI is driven by general routing
through comp clk”
This error usually occurs when general routing is used on any of clocks routed to any of the DDR modules.
Check the following:
– If using a DLL or PLL, the clock input to the DLL or PLL should be on a dedicated GDLLT or GPLLT pin. A
PCLK pin can be used but a USE PRIMARY preference must be assigned on this clock route from the PCLK
pin to a DLL or PLL.
– If an interface requires the clock to be routed directly to the ECLK or PCLK tree, the PCLK pin should be
used to input the clock. GPLLT or GDLLT pins do not have access to the PCLK or ECLK tree and cannot be
used here.
– If the clocks going to any of the DDR registers are not used in any logic inside the FPGA (like a mux function) this will cause it to get on general route.
– Refer to High-Speed DDR Interface Details to see the clock placement requirements for each type of interface.
• PAR error when assigning a DDR function to a non-DDR I/O pin:
ERROR - par: Cannot place PIO comp "datain_2" on the proposed PIO site "PB11A / AE4" because the types of
their IOLOGICs are incompatible: the associated IOLOGIC comp "datain_2_MGIOL" has been set to
"IDDR_OREG" mode (of type IDDRIOL), while the IOLOGIC site is of type XSIOLOGIC and supports FF only.
In this case an IDDRX2D1 function is placed on the bottom side pin which does not support this function, hence
the error.
See section I/O Logic (IOL) Site Types/Names to see the functions supported on each site type.
• Map Error on IDDRAPPS/ODDRAPPS function:
ERROR - map: The 'IDDRAPPS' property is missing on IDDR instance 'Inst_IDDRX2D1_1_2'. Each IDDR component targeted for this device needs the 'IDDRAPPS' property identifying the interface being implemented.
Refer to DDR usage documentation for details.
All LatticeECP3 “EA” designs require an IDDRAPPS attribute assigned to the input DDR module and an ODDRAPPS attribute assigned to the output DDR module. If these attributes are not assigned then MAP will error out
with the error message above. To fix the error, regenerate the module in IPexpress. IPexpress will generate the
module with all the required input and output DDR attributes. 12-50

Timing Analysis for High-Speed DDR Interfaces
It is recommended that the user run Static Timing Analysis in the software for each of the high-speed interfaces.
This section describes the timing preferences to use for each type of interface and the expected Trace results. The
preferences can either be entered directly in the .lpf file or through the Design Planner graphical user interface.
The External Switching Characteristics section of the LatticeECP3 Family Data Sheet should be used along with
this section. The data sheet specifies the actual values for these constraints for each of the interfaces.
Frequency Constraints
Users must explicitly specify FREQUENCY (or PERIOD) PORT preferences to all input clocks in the design. This
preference may not be required if the clock is generated out of a PLL or DLL or is input to a PLL or DLL.
DDR Input Setup and Hold Time Constraints
All of the receive (RX) interfaces, both x1 and x2, can be constrained with setup and hold preferences.
1. Receive Centered Interface
Figure 12-42 shows the data and clock relationship for a Receive Centered Interface. The clock is centered
to the data, so it comes into the devices with a setup and hold time.
Figure 12-42. RX Centered Interface Timing
Note: tSUGDDR = Setup Time, tHOGDDR = Hold Time
In this case the user must specify in the software preference the amount of setup and hold time available.
These parameters are listed in the figure as tSUGDDR and tHGDDR. These can be directly provided using the
INPUT_SETUP and HOLD preference as:
INPUT_SETUP PORT “Data” ns HOLD ns CLKPORT “Clock”;
where:
Data = Input Data Port
Clock = Input Clock Port
The External Switching Characteristics section of the LatticeECP3 Family Data Sheet specifies the minimum setup and hold times required for each of the high-speed interfaces running at maximum speed.
These values can be picked up from the data sheet if the interface is running at maximum speed.
Example:
For a GDDRX2_RX.ECLK.Centered interface on the left or right sides using a PCLK pin on the
LatticeECP3-150EA-8 device when running at the maximum speed of 405MHz, the preference would be:
INPUT_SETUP PORT "Data" 0.321 ns HOLD 0.321 ns CLKPORT "Clock”;
Note: Please check the LatticeECP3 Family Data Sheet for the latest tSUDDR and tHOGDDR numbers.

2. Receive Aligned Interface
Figure 12-43 shows the data and clock relationship for a Receive Aligned Interface. The clock is aligned
edge-to-edge with the data.
Figure 12-43. RX Aligned Interface Timing
Note: tDVACLKGDDR = Data Valid after CLK, tDVECLKGDDR = Data Hold After CLK
In this case, worst case data may occur after the clock edge resulting in a negative setup time when entering the device. The worst case setup is specified by the tDVACLKGDDR after the clock edge and the worst
case hold time is specified as tDVECLKGDDR. The setup and hold time can be specified as:
INPUT_SETUP PORT “Data” <-tDVACLKGDDR > ns HOLD < tDVECLKGDDR> ns CLKPORT
“Clock”;
where:
Data = Input Data Port
Clock = Input Clock Port
Note: A negative number is used for SETUP time as the data occurs after the clock edge in this case.
The External Switching Characteristics section of the LatticeECP3 Family Data Sheet specifies the minimum tDVACLKGDDR and tDVECLKGDDR values required for each of the high-speed interfaces running at maximum speed. These values can be picked up from the data sheet if the interface is running at maximum
speed. The data sheet numbers for this preference are listed in UI (Unit Interface). 1UI is equal to one-half
the clock period. Therefore, these numbers will need to be calculated from the clock period used.
Preference Example:
For a GDDRX2_RX.ECLK.Aligned (no CLKDIV) interface on the left or right side using DLLCLKPIN for
clock input on a LatticeECP3-150EA-8 device running at the maximum speed of 460MHz (UI = 1.09ns),
the preference would be:
t
DVACLKGDDR = 0.225UI = 0.25ns, tDVECLKGDDR = 0.775UI = 0.84ns
The preference for this case is:
INPUT_SETUP PORT "Data" -0.250000 ns HOLD 0.840000 ns CLKPORT "Clock”;
Note: Please check the LatticeECP3 Family Data Sheet for the latest tDVACLKGDDR and tDVECLKGDDR numbers.

data delay will be dynamically updated at run time.

DDR Clock to Out Constraints for Transmit Interfaces
All of the transmit (TX) interfaces, both x1 and x2, can be constrained with clock-to-out constraints to detect the
relationship between the clock and data when leaving the device.
Figure 12-44 shows how the clock-to-out is constrained in the software. Minimum tCO is the minimum time after the
clock edge transition that the data will not transition. So any data transition must occur between the tCO minimum
and maximum values.
Figure 12-44. tCO Minimum and Maximum Timing Analysis
1. Transmit Centered Interfaces
In this case, the transmit clock is expected to be centered with the data when leaving the device. Figure 12-
45 shows the timing for a centered transmit interface.
Figure 12-45. Transmit Centered Interface Timing
Figure 12-45 shows that the maximum value after which the data cannot transition is -tDVBCKGDDR. The
minimum value before which the data cannot transition is -(tU + tVBCKGDDR). A negative sign is used
because in this particular case where clock is forwarded centered-aligned to the data, these two conditions
occur before the clock edge.
The LatticeECP3 Family Data Sheet specifies the tDVBCKGDDR and tDVACKGDDR values at maximum speed.
But we do not know the tU value, so the minimum tCO can be calculated using the following equation.
t
CO Min. = -(tDVBGDDR + tU)
½T = tDVAGDDR + tDVBGDDR + tU

CLKPORT “clk” CLKOUT PORT “Clock”;
where:
Data = Data Output Port
Clock = Forwarded Clock Output Port
clk = Input Clock Port
The values for tDVBCKGDDR and tDVACKGDDR can be found in the External Switching Characteristics section
of the LatticeECP3 Family Data Sheet for the maximum speed.
Preference Example:
For a GDDRX1_TX.SCLK.Centered interface running on the LatticeECP3-150EA-8 device at 250MHz,
t
DVBGDDR = tDVAGDDR = 0.670ns, the preference would be:
CLOCK_TO_OUT PORT "Data" MAX -0.670000 ns MIN -1.330000 ns CLKPORT "clk"
CLKOUT PORT "Clock”;
Note: Please check the LatticeECP3 Family Data Sheet for the latest tDVAGDDR and tDVBGDDR numbers.
2. Transmit Aligned Interfaces
In this case, the clock and data are aligned when leaving the device. Figure 12-46 shows the timing diagram for this interface.
Figure 12-46. Transmit Aligned Interface Timing
Figure 12-46 shows that maximum value after which the data cannot transition is tDIAGDDR. The minimum
value before which the data cannot transition is -tDIBGDDR. A negative sign is used for the minimum value
because the minimum condition occurs before the clock edge.
The clock to out time in the software can be specified as:

Timing Rule Check for Clock Domain Transfers
Clock Domain Transfers within the IDDR and ODDR modules are checked by Trace automatically when these elements are used in a design. Most clock domain transfers occur in the IDDRX2 and ODDRX2 modules where there
are fast-speed and slow-speed clock inputs. For IDDRX2, there is a transfer from the fast-speed ECLK to the slowspeed SCLK. On the ODDRX2, the transfer happens from the slow-speed SCLK to the fast-speed ECLK.
For ispLEVER 8.0, no special preferences are needed to run this check. The clock domain transfer checks are
automatically done by the software and reported in the Trace report under section called “Timing Rule Check”. The
report lists the timing for the both the input and output DDR blocks where a clock domain transfer is done.
Figure 12-47 shows the transfer of data between the ECLK and SCLK for the IDDRX2 block. A cause of concern is
the phase relationship between the ECLK and SCLK. As in the waveforms below, these two clocks have to maintain a certain amount of skew to transfer data successfully between the two clocks.12-55
LatticeECP3 High-Speed
I/O Interface
Figure 12-47. IDDRX2 ECLK to SCLK Transfer
The skew between the two clocks is specified in terms of “min.” skew and “max.” skew. Figure 12-48 shows how the
“min.” and “max.” skew is measured for the IDDRX2 block. It is required that the “min.” and “max.” skew be within
the specified “min.” and “max.” specs.

The following equations are used to check for valid skew between the ECLK and SCLK for an IDDRX2 block.

Note: For paths that are common between the ECLK and CLK, the same delay will be used. For example, since
PADI_DEL is the shared path between the Max. ECLK and Min. CLK for “Max skew calculation” and between Min.
ECLK and Max. CLK for “Min skew calculation” the value is the same in both cases.
The “ECLK to CLK skew range from -2.510 ns to -0.019 ns” for this case is an allowable skew range between the
two clocks.The skew between the two clocks must fall within this range or the Trace will fail on this preference. The
allowable skew range is determined by the frequency at which the fast ECLK clock is running.12-57
LatticeECP3 High-Speed
I/O Interface
Similarly for the ODDRX2D, there is an internal transfer from SCLK to DQCLK0/1 which will be listed in the Timing
Rule Check section as well.
This internal rule check is required for normal data pins but is not required for the forwarded clock output itself
where data inputs to the ODDRX2D are constants. There is no internal data transfer in this case. Users can ignore
Trace reported errors on this Internal Rule Check only for forwarded clocks. These errors may be blocked by a preference like:
BLOCK NET "sclk_c" COMP "clkout_MGIOL";
Where sclk_c is the net on the CLK pin of the IOLOGIC component clkout_MGIOL, where clkout is the forwarded
clock. Trace violations of this rule check on corresponding data outputs need to be understood and resolved.
Preferences for Specific Elements
1. DLLDELB – This element is used in to generate a 90° delay in all receive aligned interfaces. The 90° delay
is calculated based on the input clock to the TRDLLB element. A frequency preference must be provided
on the CLKI of the TRDLLB to allow trace to produce the 90° delay.
2. DQSBUFx – The DQSBUF element used in all the DQS interfaces will delay the DQSI input by 90°. The
90° delay is calculated from the input clock to the DQSDLL element connected via the DQSDEL signal. A
frequency preference must be provided on the CLK input of the DQSDLL to allow trace to produce the 90°
delay.
The DDR Software Primitives and Attributes section provides a detailed description of the DQSBUF elements.
Note: Some device I/O pin names end with an “E_A”, “E_B”, “E_C” or “E_D” (for example, PR43E_B). These pins
are “Input Only” pins. These pins can be used only to implement receive interfaces. The clock delay to these pins is
~50ps longer than the other pins, so you will see some difference in timing between these and other I/O pins.
Valid Window Calculation
Users can calculate the available valid window using the transmitter device specifications to determine if it will be
possible to meet the receiver timing requirements at the LatticeECP3 device.
The data sheet numbers can be used to estimate the required valid window at the LatticeECP3 DDR inputs
depending on the interface type.
For an Rx centered interface the total data valid window required = tSUGDDR + tHGDDR
For an Rx aligned interface the total data valid window required = tDVECLKGDDR - tDVACLKGDDR
For example, in the following case the data at the receiver looks like Figure 12-49.
Figure 12-49. Data at Receiver (Tx Data)
In this case, the data at the LatticeECP3 input is an aligned interface, with the following timing:12-58
LatticeECP3 High-Speed
I/O Interface
Data Rate = 594 Mbps
f
MAX = 297 MHz
Uncertainty around clock edges = 0.350ns
UI = 1.684ns
Since this is an aligned interface, we can calculate tDVECLKGDDR and tDVACLKGDDR to determine the available Data
Valid Window.
t
DVECLKGDDR = 0.350 ns
t
DVACLKGDDR = 1.684 ns – 0.350 ns = 1.334 ns
Data Valid Window = tDVECLKGDDR - tDVACLKGDDR = 0.984 ns
On the LatticeECP3 receive side, we must use the GDDRX2_RX.ECLK.Aligned interface given the frequency and
data to clock alignment of this interface.
For the GDDRX2_RX.ECLK.Aligned for the -6 speed grade, here are the requirements from the data sheet at 297
MHz.
t
DVECLKGDDR = 0.225 UI = 0.379ns
t
DVACLKGDDR = 0.775 UI = 1.305ns
Data Valid Window = tDVECLKGDDR - tDVACLKGDDR = 0.926ns
Note: Please refer to the LatticeECP3 Family Data Sheet for the latest timing numbers.
The required data valid window for this example at the LatticeECP3 DDR input is 0.926 ns and the data valid window available on the interface is 0.984ns. This interface will just meet the timing requirements at the LatticeECP3
device.
To calculate the worst corner case, the software I/O Timing Analysis should be run to see if the worst case required
timing will be met. I/O Timing Analysis will run the timing through all the speed grades of the device family and
show the worst case results. The Trace Report will provide the worst case timing on the same speed grade.
DDR/DDR2/DDR3 SDRAM Interfaces Overview
The DDR SDRAM interface transfers data at both the rising and falling edges of the clock. The DDR2 is the second
generation of the DDR SRDRAM memory, whereas DDR3 is the third generation.
The DDR, DDR2 and DDR3 SDRAM interfaces rely on the use of a data strobe signal, called DQS, for high-speed
operation. The DDR SDRAM interface uses a single-ended DQS strobe signal and the DDR2 and DDR3 interfaces
use a differential DQS strobe. The figures below show typical DDR and DDR2/DDR3 SDRAM interface signals.
SDRAM interfaces are typically implemented with eight DQ data bits per DQS. So, a x16 interface will use two DQS
signals, and each DQS is associated with eight DQ bits. Both the DQ and DQS are bi-directional ports and are
used to read and write to the memory.
When reading data from the external memory device, data coming into the device is edge-aligned with respect to
the DQS signal. This DQS strobe signal needs to be phase shifted 90° before the FPGA logic can sample the read
data. When writing to a DDR/DDR2/DDR3 SDRAM, the memory controller (FPGA) must shift the DQS by 90° to
center-align with the data signals (DQ). A clock signal is also provided to the memory. This clock is provided as a
differential clock (CLKP and CLKN) to minimize duty cycle variations. The memory also uses these clock signals to
generate the DQS signal during a read via a DLL inside the memory. The figures below show DQ and DQS timing
relationships for read and write cycles.12-59
LatticeECP3 High-Speed
I/O Interface
During read, the DQS signal is low for some duration after it comes out of tristate. This state is called Preamble.
The state when the DQS is low before it goes into tristate is the Postamble state. This is the state after the last valid
data transition.
DDR SDRAM also requires a Data Mask (DM) signal to mask data bits during write cycles. Note that the ratio of
DQS to data bits is independent of the overall width of the memory. An 8-bit interface will have one strobe signal.
DDR SDRAM interfaces use the SSTL25 Class I/II I/O standards, DDR2 SDRAM interface uses the SSTL18 Class
I/II and DDR3 SDRAM interface uses the SSTL15 I/O standards. Both the DDR2 and DDR3 SDRAM interfaces
require differential DQS (DQS and DQS#). DDR2 has an option to use either single-ended or differential DQS.
In addition, the DDR3 memory module uses fly-by architecture for the data and strobe signals. This requires the
memory controller to support read and write leveling to adjust for leveled delay on read and write data transfers.

the use of a data strobe signal, called DQS, for high-speed operation. When reading data from the external memory device, data coming into the LatticeECP3 device is edge-aligned with respect to the DQS signal. Therefore, the
LatticeECP3 device needs to shift the DQS (90° phase shift) before using it to sample the read data. When writing

I/O Interface
to a DDR SDRAM from the memory controller, the LatticeECP3 device must generate a DQS signal that is centeraligned with the DQ, the data signals. This is accomplished by ensuring a DQS strobe is 90° shifted relative to the
DQ data.
For DDR3 memory, the memory controller also needs to handle the read and write leveling required by the interface due to the newer fly-by topology.
LatticeECP3 devices have dedicated DQS support circuitry for generating appropriate phase-shifting for DQS. The
DQS phase shift circuit uses a frequency reference DLL to generate delay control signals associated with each of
the dedicated DQS pins, and is designed to compensate for process, voltage and temperature (PVT) variations.
The frequency reference is provided through one of the global clock pins. The dedicated DDR support circuit is also
designed to provide comfortable and consistent margins for the data sampling window.
This section describes how to implement the read and write sections of a DDR memory interface. It also provides
details of the DQ and DQS grouping rules associated with the LatticeECP3 devices.
Both the LatticeECP3 “E” and “EA” devices can be used to implement DDR and DDR2 memory interfaces. DDR3
memory interface can only be implemented on the “EA” devices. There are some differences in the DDR memory
implementation between the “EA” and “E” devices. These differences between the devices are indicated in the
appropriate sections below.
See the LatticeECP3 DDR3 Memory Controller IP to see how the DDR3 memory interface can be implemented on
LatticeECP3 “EA” devices. DDR and DDR2 memory interface implementations are described in the sections below.
DQS Grouping
Each DQS group generally consists of at least 10 I/Os (one DQS, eight DQ and one DM) for an 8-bit DDR/DDR2
memory interface or 11 I/Os (two DQS, eight DQ, one DM) to implement a complete 8-bit DDR3 memory interface.
LatticeECP3 devices support DQS signals on the top, left and right sides of the device.
Each DQS signal spans across 12 I/Os. Any 10 (for DDR/DDR2) or 11 (for DDR2/DDR3) of these 12 I/Os spanned
by the DQS can be used to implement an 8-bit DDR memory interface. In addition to the DQS grouping, the user
must also assign one reference voltage VREF1 for a given I/O bank.
Figure 12-54. DQ-DQS Grouping
Figure 12-54 shows a typical DQ-DQS group for LatticeECP3 devices. The seventh I/O of this group of 12 I/Os is
the dedicated DQS pin. All six pads before of the DQS and five pads after the DQS are covered by this DQS bus
span. If using DDR2 or DDR3 memory then the DQS is differential and the eighth pad is used by the DQS# signal.
The user can assign any eight of the other I/O pads to be DQ data pins. Therefore, to implement a 32-bit wide
memory interface you would need to use four such DQ-DQS groups.
When not interfacing with the memory, the dedicated DQS pin can be used as a general-purpose I/O. Note that the
DQS/DQS# pads cannot be used for other DDR functions like DQ, DM or generic DDR. Each of the dedicated DQS
pins is internally connected to the DQS phase shift circuitry. The pinout information contained in the LatticeECP3
Family Data Sheet shows pin locations for the DQS pads and the corresponding DQ pads.

Some I/Os on the left, right and top sides will not support DQS grouping. See the DDR Memory DQ/DQS Design
Rules and Guidelines section of this document for further information.
Memory Read Implementation
The LatticeECP3 devices contain a variety of features to simplify implementation of the read portion of a DDR interface:
• DLL-compensated DQS delay elements
• DDR input registers
• Automatic DQS to system/edge clock domain transfer circuitry
• Data Valid Module
DLL-Compensated DQS Delay Elements
The DQS from the memory is connected to the DQS Delay element. The DQS delay block receives a 7-bit delay
control from the on-chip DQSDLL. LatticeECP3 devices support two DQSDLL, one on the left and the other on the
right side of the device. The DQSDEL generated by the DQSDLL on the left side of the device is routed to all the
DQS blocks on the left and top halves of the device. The delay generated by the DQSDLL on the right side of the
device is distributed to all the DQS delay blocks on the right side and the top half of the device. There are no DQS
pins on the bottom banks of the device. These digital delay control signals are used to delay the DQS from the
memory by 90°.
The DQS received from the memory is delayed in each of the DQS delay blocks and this delay DQS is used to
clock the first set stage DDR input registers.
Automatic DQS to System/Edge Clock Domain Transfer Circuitry
In a typical DDR memory interface design, the phase relation between the incoming delayed DQS strobe and the
internal system clock (during the read cycle) is unknown. Prior to the read operation in DDR memories DQS is in
tristate. Coming out of tristate, the DDR memory device drives DQS low in the preamble state. The DQS Transition
Detect block detects this transition and generates a signal indicating the required polarity for the FPGA system
clock (DDRCLKPOL). This signal is used to control the polarity of the clock to the synchronizing registers. For the
DDR3 memory interface, this block generates two signals, DDRCLKPOL and DDRLAT. DDRCLKPOL is used to
transfer data from the DDR registers to the synchronization registers clocked by ECLK and the DDRLAT signal is
used to transfer data from the synchronization registers to the clock transfer registers.
Data Valid Module
The data valid module generates a DATAVALID signal. This signal indicates to the FPGA that valid data is transmitted out the input DDR registers to the FPGA core. Note that the DATAVALID signal indicates only the start of valid
read data. It is the memory controller’s responsibility to make the proper width of the read data valid signal.
DDR I/O Register Implementation
The first set of DDR registers is used to de-mux the DDR data at the positive and negative edges of the phaseshifted DQS signal. The latch that captures the positive-edge data is followed by a negative-edge triggered register.
This register transfers the positive edge data from the first register to the negative edge of DQS so that both the
positive and negative portions of the data are now aligned to the negative edge of DQS.
For DDR and DDR2 memory interfaces, the second stage synchronization registers are clocked by the FPGA
clock. The polarity of this clock is selected by the DDR Clock Polarity (DDRCLKPOL) signal generated by the DQS
Transition Detect Block. The FPGA clock clocks an additional set of clock transfer registers at the end before the
data enters the FPGA core.
The DDR3 memory interface uses the gearing feature of the input registers. The synchronization registers are
clocked by the fast edge clock (ECLK) input and are then transferred to the clock transfer registers clocked by the
slower FPGA clock. The polarity of the ECLK is set by the DDRCLKPOL signal and the FPGA clock (SCLK) polarity is set by the DDRLAT signal.12-63

The LatticeECP3 Family Data Sheet describes each of these circuit elements in more depth.
DDR/DDR2 Memory Read Implementation
The following sections explain the DDR/DDR2 read-ide implementation. LatticeECP3 devices support the
DDR/DDR2 memory interface function using the DDR memory mode module generated through the IPexpress
tool. Using IPexpress, a designer can generate the different modules required to read the data coming from the
DDR/DDR2 memory. See the section DDR Memory Interface Generation Using IPexpress for details on the IPexpress interface. This section explains the read side module generated by IPexpress.
The DDR/DDR2 read side is implemented using the following three software elements. The DQSDLL represents
the DLL used for calibration. The IDDRXD implements the input DDR registers. The DQSBUFF represents the
DQS delay block, the clock polarity control logic and the Data Valid module. Figure 12-55 shows the read side
implementation for both the “E” and “EA” devices. IPexpress should be used to generate this interface. See the section DDR Memory Interface Generation Using IPexpress for details.12-64

Memory Write Implementation
To implement the write portion of a DDR memory interface, two streams of single data rate data must be multiplexed together with data transitioning on both edges of the clock. In addition, during a write cycle, DQS must arrive
at the memory pins center-aligned with data, DQ. Along with the DQS strobe and DQ, CLKP, CLKN, Address/Command and Data Mask (DM) signals also need to be generated. IPexpress should be used to generate this interface.

Challenges encountered during memory write:
• Differential CLK signals (CLKP and CLKN) need to be generated.
• Generate ADDR/CMD signal edge-aligned to CLKP falling edge.
• DQS needs to be edge-aligned to CLKP. In DDR3 interfaces where fly-by routing is used, write leveling should be
used to compensate for skews between CLKP and DQS.
• DQ/DM needs to be center-aligned to DQS and therefore center-aligned to CLKP as well.
• The controller must meet the DDR interface specification for the tDSS and tDSH parameters, defined as DQS falling edge setup and hold time to/from CLKP rising edge, respectively. The skews, if caused by the fly-by topology,
are compensated by write-leveling.
• The DDR output data must be muxed from two SDR streams into a single outgoing DDR data stream. For the
DDR3 memory interface, this DDR output data is generated from four SDR streams.
The DDR/DDR2 memory write interface is implemented using the following modules:
• IDDRXD, ODDRXD, OFD1S3AX – Used for DDR2 DQ input, output and tri-state control. DDR2 DM uses ODDRXD and OFD1S3AX only.
• ODDRXDQSA, ODDRTDQSA – Used for DDR2 DQS output and tri-state control.
• DQSBUFF – Dedicated for DDR2 memory interface application.
• DQSBUFG – Generic ODDRXD support for clocks on “E” devices.
• ODDRXD – Generic DDR mode for clocks on “E” devices.
• ODDRXD1 – Generic DDR mode for clocks on “EA” devices.
DDR/DDR2 Internal Clock Generation
LatticeECP3 devices require two clocks to implement a DDR/DDR2 memory interface. SCLK (k_clk) is used to
generate the data and data strobe signals while a 270° shifted clock, SCLK1 (k1_clk), is needed to generate the
memory clock and address/command signals. Figure 12-57 shows the generation of these clocks using a PLL.
SCLK is also used for the read side implementation as described in Figure 12-55.
Figure 12-57. DDR/DDR2 Internal Clock Generation
DDR/DDR2 Memory Write Implementation
The following sections explain the DDR/DDR2 write side implementation. LatticeECP3 devices support the
DDR/DDR2 memory interface function using the DDR memory mode module generated through the IPexpress
tool.Using IPexpress, a designer may generate the Data (DQ), Strobe (DQS), Data Mask, Clock (CLKP/CLKN),
Address/Command (ADDR/CMD) signals required when writing to the DDR memory. See the section DDR Memory Interface Generation Using IPexpress for details on the IPexpress Interface. This section explains the different
Write Side modules generated by IPexpress.
DDR/DDR2 Write Side Data (DQ) and Strobe (DQS) Generation
Figure 12-58 shows the DDR2 write side for data and strobe generation. The DQCLK1 and DQSW are signals generated in the DQSBUFF module. DQCLK0 is not used for the DDR2 memory interface. For details on each element, refer to the DDR Software Primitives and Attributes section. The DDR2 memory interface does not require

“E” devices the ODDRXD primitive is used to generate the clocks. The left and right sides of the “E” devices also
require the DQSBUFG which is used to generate the DQCLK1 required in the ODDRXD module. The top side of
the “E” device does not require the use of DQSBUFG and the DQCLK1 input of the ODDRXD can be tied to SCLK.
The “EA” device uses the ODDRXD1 element instead. “EA” devices do not require the use of the DQSBUFG element.
The inputs to the ODDRXD/ODDRXD1 are tied to constant values to generate a clock out of the ODDRXD/ODDRXD1. When interfacing to the DDR SDRAM memory, CLKP should be connected to the SSTL25D I/O
Standard and when interfacing to DDR2 memory it should be connected to SSTL18D I/O Standard to generate the
differential clock outputs. Generating the CLKN in this manner will prevent skew between the two signals.

DDR3 Memory Write Implementation
The following sections explain the DDR3 write side implementation. LatticeECP3 devices support the DDR3 memory interface function using the DDR memory mode module generated through the IPexpress tool. Using IPexpress, a designer may generate the Data (DQ), Strobe (DQS), Data Mask, Clock (CLKP/CLKN) and
Address/Command (ADDR/CMD) signals required when writing to the DDR3 memory. See the section DDR Memory Interface Generation Using IPexpress for details on the IPexpress Interface. This section explains the different
write side modules generated by IPexpress.
The DDR3 memory interface generated in IPexpress also includes a Clock Synchronization Module (CSM) that
provides the clock synchronization and alignment among the required clocks for successful DDR3 functionality.
DDR3 Data (DQ) and Strobe (DQS) Generation
Figure 12-63 shows the DDR3 write side implementation for data (DQ) and strobe (DQS) generation. The
DQCLK0, DQCLK1 and DQSW are signals generated in the DQSBUFD module. ODDRX2D implements the output
DDR registers in x2 gearing mode required for DDR3 DQ generation. The ODDRX2DQSA module is used to generate the DQS strobe output. For details on each element, refer to the DDR Software Primitives and Attributes section.
The DDR3 memory interface requires write leveling which is supported with the DYNDELAY [6:0] and DYNDELPOL inputs of DQSBUFD. Users can provide the delays for each DQS group using these ports. They are available
to the user as ports in the top-level module generated by IPexpress.
The ECLK, SCLK2X and SCLK are generated in a clock synchronization module (CSM) that provides the clock
synchronization and alignment among the required clocks for successful DDR3 functionality. See the DDR3 Clock
Synchronization Module section for details on the Clock Synchronization Module.
IPexpress is used to generate these signals. Figure 12-63 shows the module generated by IPexpress data (DQ)
and strobe (DQS) generation.12-72

DDR3 Write Side Clock (CLKP/CLKN) Generation
The SCLK2X out of the Clock Synchronization Module is used to generate the DDR clock outputs. See the section
DDR3 Clock Synchronization Module for details.
The ODDRXD1 element is used to generate the clock. The inputs to the ODDRXD1 are tied to constant values to
generate a clock out of the ODDRXD1. When interfacing to the DDR3 SDRAM memory, CLKP (ddrclkP) should be
connected to the SSTL15D I/O standard to generate the differential clock outputs. Generating the CLKN (ddrclkN)
in this manner will prevent skew between the two signals

DDR3 Clock Synchronization Module
The DDR3 memory interface generated in IPexpress includes a clock synchronization module (CSM) that provides
the clock synchronization and alignment among the required clocks for successful DDR3 functionality. A DDR3
memory interface that is implemented in LatticeECP3 must use the CSM block for correct read data transfer from
the ECLK to SCLK domain. It is also used to provide the proper clock relationship between SCLK and DQCLK0/1
used for write data generation.
The CSM block generates the ECLK, SCLK2X and SCLK clocks to be used in the read and write side implementations. It generates a clocking_good output to indicate that all the clocks for DDR3 operation have been synchronized and the device is ready to serve the DDR3 operation. The DDR3 memory interface and controller should wait
until the clocking_good signal is detected as high.
The DDR3 mode supports the write leveling feature by providing the dynamic delay control ports inputs (DYNDELAY) of DQSBUFD to users. In order for the CSM block to support write leveling, the reset_datapath input port
should be asserted high for at least one PLL input clock cycle (pll_clk) to reset the DQSBUFD blocks through the
reset_datapath_out signal after a write leveling operation is finished. The reset_datapath_out signal is directly connected to the reset (RST) port of all DQSBUFD.
Figure 12-66 shows the block diagram of the CSM block.

PLL Settings for Clock Synchronization Module: LatticeECP3 devices allow two dedicated PLL blocks per side
to support the DDR3 memory interface applications. One of the four available PLLs (two PLLs in the left side and
two PLLs in the right side) must be used to implement the CSM block. Since the PLL input clock is also used to
control the synchronization logic, the use of a PLL input clock that is too fast may cause failures in PAR timing
results. Therefore, it is recommended to use the 1:2:4 clock multiplication ratios for high-speed DDR3 memory
interface applications as shown in the example of a 400MHz/800Mbps DDR3 memory interface below. A dedicated
PLL input clock pad or a PCLK pad can be used to drive the selected PLL.
Table 12-8. PLL Settings for 400 MHz DDR3 Operation
Timing Preferences for Clock Synchronization Module: Since the CSM block includes a few timing-sensitive
nets that affect the performance of DDR3 I/O functions, the route delays on these nets should be tightly controlled.
To consistently guarantee successful routing results, these nets should be constrained by the MAXDDELAY preferences. The nets shown in Table 12-9 include the net delay preferences to force the software Place and Route
(PAR) tool to meet the required net delays.
Table 12-9. MAXDELAY NET Preferences for Clock Synchronization Module
The preferences for the constrained PAR targets are located in the HDL module generated by IPexpress. It is automatically transferred to the project preference file (.prf) to achieve the optimum timing results.
The example shown below includes the target preferences with the following conditions:

LOCATE PGROUP "clk_stop" SITE "R60C2D";
LOCATE PGROUP "rst_dp_out" SITE "R60C4D";
The following block paths should also be included to help avoid unnecessary domain crossing nets being reported
in the trace report as false alarms.

DDR Memory Interface Generation Using IPexpress
The IPexpress tool is used to configure and generate the DDR, DDR2 and DDR3 memory interfaces. This section
assumes that ispLEVER 8.0 SP1 is used for generation of the interfaces. If you are using ispLEVER 7.2 SP2, see
Appendix A. Building DDR Interfaces Using IPexpress in ispLEVER 7.2 SP2. If you are using Lattice Diamond
design software, see Appendix B. Building SDR/DDR Interfaces Using IPexpress in Diamond.
To see the detailed block diagram for each interface generated by IPexpress see the Memory Read Implementation
and Memory Write Implementation sections.

DDR Memory DQ/DQS Design Rules and Guidelines
Listed below are some rules and guidelines to keep in mind when implementing DDR memory interfaces in
LatticeECP3 devices.
• LatticeECP3 devices have dedicated DQ-DQS banks. Please refer to the Logical Signal Connections tables in
the LatticeECP3 Family Data Sheet before locking these pins.
• There are two DQSDLLs on the device, one for the left half and one for the right half of the device. Only one
DQSDLL primitive should be instantiated for each half of the device. Since there is only one DQSDLL on each
half, all the DDR memory interfaces on that half should run at the same frequency.
• Each DQSDLL will generate 90° digital delay bits for all the DQS delay blocks on that half of the device based on
the reference clock input to the DLL.
• The clock to the PLL used in the write implementation to generate the clocks for the outputs must be locked to
the correct dedicated PLL pin input.
• When implementing a DDR SDRAM interface, all interface signals should be connected to the SSTL25 I/O standard.
• For the DDR2 SDRAM interface, the interface signal should be connected to the SSTL18 I/O standard.
• For the DDR3 SDRAM interface, these signals should be connected to the SSTL15 standard.
• The DDR, DDR2 and DDR3 require a differential clock signal. For these standards, the differential clock signals
should be connected to SSTL25D (DDR), SSTL18D (DDR2) or SSTL15D (DDR3).
• DDR3 also requires differential DQS signal. The use of differential DQS is optional for DDR2. If differential DQS
is used it should be connected to SSTL18D for DDR2 and SSTL15D for DDR3.
• When implementing the DDR interface, the VREF1 of the bank is used to provide the reference voltage for the
interface pins. VREF1 should not be connected with VREF2 of the bank when implementing DDR memory interfaces.
• There is no DQS strobe support on the bottom of the device, so memory interfaces cannot be implemented on
this side.
• Within a DQS-12 group, the IOLOGIC in the group’s DQS/DQS# pads cannot be used for DDR registers.
• If the register is implemented inside the FPGA fabric instead of the IOLOGIC, there is no restriction on using the
DQS pad.

LatticeECP3 High-Speed
I/O Interface
• The upper left corner of the LatticeECP3 device has a non-DQS DDR group. This group of I/Os does not have a
DQS function. This group of I/Os can only be used for generic DDR implementations.
• IDDRX memory cannot be mixed in the same DQS group as an ODDRX generic implementation. Similarly,
ODDRX memory cannot be mixed in the same DQS group with an IDDRX generic implementation.
• Generic DDR interfaces are not available on the top side of the LatticeECP3 “E” device only. The generic DDR
required for DDR clock and control generation needs to be implemented on the left and right sides of the device.
Generic DDR interfaces can be implemented on the top side of the “EA” devices, therefore this issue does not
exist for “EA” devices.
• Table 12-13 summarizes what is available on each side of the LatticeECP3-70E, LatticeECP3-95E and
LatticeECP3-150EA devices. Note that DDR registers are not available on the bottom of the device.
Table 12-13. DDR Pin Limitations
DDR/DDR2 Pinout Guidelines
• The DQS-DQ association rule must be followed.
– All associated DQs (8 or 4) to a DQS must be in the same DQS-12 group.
• The data mask (DM) must be part of the corresponding DQS-12 group.
– Example: DM[0] must be in the DQS-12 group that has DQ[7:0], DQS[0].
• DQS pad must be allocated to a dedicated DQS pad.
– DQS# pad is used when differential DQS is selected.
• Do not assign any signal to the DQS# pad if SSTL18D is applied to the DQS pad.
– The software automatically places DQS# when SSTL18D is applied.
• DQS/DQS# pads cannot be used for other DDR functions.
– The DQS IOLOGIC structure is not compatible with non-DQS DDR IOLOGIC.
• The clock to the PLL used to generate the outputs must be assigned to use dedicated clock routing.
• Data group signals (DQ, DQS, DM) can use either the left, right or top edge of LatticeECP3.
• Locating memory clock signals:
– For the LatticeECP3 “E” device, it is highly recommended to have all clock pads within a memory controller
be in one DQS-12 group to minimize pinout restrictions.
• The bottom-side pads in Bank 6 and Bank 3 are also good candidates for address/command/control signals.
Save pins on the left and right sides for DDR.
• VREF1 of the bank where DQs are located must not be taken by any signal.

I/O Interface
– VREF2 is OK to use.
– Do not connect VREF1 and VREF2 together.
• External termination to VTT is required for DDR and DDR2 interfaces. All DQ and DQS pins must be terminated
to VTT using an external termination resistor. VTT = ½ VCCIO (0.9V for DDR2 and 1.25V for DDR). It is recommended that SI Simulation be run to determine the best termination value. If signal integrity simulation is not
available, parallel termination of 75ohms to VTT should be used.
• It is required to provide a PCB connect resistor to the XRES pins. These pins cannot be used for other functions.
See TN1189, LatticeECP3 Hardware Checklist, for detailed requirements on the XRES pin.
DDR3 Termination Guidelines
Proper termination of a DDR3 interface is an important part of implementation that ensures reliable data transactions at high speed. Below is the general termination guideline for the LatticeECP3 DDR3 interface.
Termination for DQ, DQS and DM
• Do not locate any termination on the memory side. The memory side termination on DQ, DQS and DM is dynamically controlled by the DDR3 SDRAM's ODT function.
• External termination to VTT is required for DDR3 interfaces at the FPGA side. Each DQ and DQS pin should be
terminated to VTT using an external termination resistor. The termination resistor location is important. See the
Layout Considerations for DDR3 section for the requirements.
• It is recommended that signal integrity (SI) simulation be run to determine the best termination value. If SI simulation is not available, parallel termination of 100 ohms to 120 ohms to VTT is recommended.
• Use of series termination resistors at the FPGA side is not recommended.
Termination for CK
DDR3 memory clocks require differential termination because they use a differential signaling, SSTL15D, in DDR3
SDRAM applications. You can locate an effective 100-ohm termination resistance on the memory side to achieve
the differential termination using the following guideline:
• Locate a 100-ohm resistor between the positive and negative clock signal, or
• Connect one end of an Rtt resistor to the positive pin and one end of another Rtt to the negative pin of a CK pair,
then connect the other ends of two Rtt resistors together and return to VDD through a Ctt capacitance. This is a
JEDEC CK termination scheme defined in the DIMM specifications. JEDEC uses 36-ohm for Rtt with 0.1uF Ctt
for DIMM. 50-ohm Rtt can also be used for non-DIMM applications.
• Use of series termination resistors at the FPGA side is not recommended.
• When fly-by wiring is used, the CK termination resistor should be located after the last DDR3 SDRAM device.
Termination for Address, Commands and Controls
Parallel termination to VTT on address, command and control lines is typically required.
• Locate a 50-ohm parallel-to-VTT resistor (or a best known resistance obtained from your SI simulation) to each
address, command and control line on the memory side.
• When fly-by wiring is used, the address, command and control termination resistors should be located after the
last DDR3 SDRAM device.
• Series termination resistors can be optionally used on the address, command and control signals to suppress
overshoot/undershoot and to help decrease overall SSO noise level. 22-ohm or 15-ohm series termination is recommended when used. 12-84
LatticeECP3 High-Speed
I/O Interface
Termination for DDR3 DIMM
The DDR3 SDRAM DIMMs incorporate internal termination following the requirements defined by the JEDEC
DIMM specification. For this reason, the user termination requirement for the DDR3 DIMM is slightly different from
that of DDR3 SDRAM devices.
• Do not locate any termination on the memory side. The memory side termination on DQ, DQS and DM is dynamically controlled by the DDR3 SDRAM’s ODT function.
• Do not locate differential termination on CK at the memory side.
• Do not locate parallel termination to VTT on address, command and control signals at the memory side.
• Follow the termination for DQ, DQS and DM guideline above for the FPGA side termination.
DDR3 Interface without Termination
When a wide DDR3 data bus is implemented and requires most of the pin resources in the assigned banks to be
used as data lines, SSO impact usually becomes a designer’s concern. While proper use of termination resistors
provides optimized signal integrity results, removing them may also provide improved noise margin in some cases
due to increased eye height.
DQ, DQS and DM without Parallel VTT Termination
Although the external parallel VTT termination is typically required for read operations at the FPGA side, it can be
removed if the following conditions are met:
a. Point-to-point connection between FPGA and DDR3 SDRAM device
b. PCB trace length is maintained shorter than 3.0"
c. SI simulation confirms that there is no significant reflection or ringing noise due to unmatched line impedance
Either or both of the following considerations are suggested when you implement a DDR3 interface without external
VTT termination:
• You can still keep the external VTT termination in your PCB layout without population if the board space allows. It
will give you an opportunity to return to the external termination scheme without board re-spin work.
• You can connect the VTT input pads in the banks where the DDR3 interface’s data bus is implemented to the
external VTT source. This will allow you to use the LatticeECP3's internal on-chip termination on selective signals in case only a few have bad signal integrity results. This approach also allows you to use internal VTT termination only on DQS signals, which can be a useful termination option in some cases.
Address, Command and Control Signals without Parallel VTT Termination
As described, parallel termination to VTT on address, command and control lines is typically required. However,
the parallel VTT termination on them can also be optionally removed to increase the noise margin or to avoid layout
difficulties at the memory side. When they are removed, use of series termination resistors at the driver side
(FPGA) is recommended to suppress overshoot and undershoot noise. The same condition as specified above for
DQ, DQS and DM is applied to remove the parallel termination.
Layout Considerations for DDR3
• Placement of external discrete resistors or resistor packs (RPACKS) for parallel VTT termination is critical and
must be placed within 0.6 inches (600-mil) of the FPGA ball.
– 120 ohm BGA RPACKS (CTS RT2432B7 type) are recommended for the 64- and 32-bit interfaces due to
better routing and density issues. Each RPACK contains 18 resistors in a very small BGA footprint. Note that
only 120, 75 and 50 ohm values are available in this package type.
– 4x1 RPACKS (CTS 741X083101JP type) can also be used in cases where a 100 ohm value is needed with-12-85
LatticeECP3 High-Speed
I/O Interface
out routing/density issues.
• The termination resistor stubs should be kept minimal.
• All traces should be matched to 50 ohms.
• For SODIMM and UDIMM designs, write leveling should be used and all traces from the FPGA to the DIMM
should be matched in length on the PC board similar to DDR2.
• If using a discrete DDR3 device, fly-by routing can be used for traces. If fly-by routing is used, the Write Leveling
option must be enabled. If not using fly-by routing, the Write Leveling option must be disabled.
• Refer to TN1189, LatticeECP3 Hardware Checklist, DDR3 Interface Requirements section for complete DDR3
layout guidelines.
DDR3 Pinout Guidelines
The LatticeECP3 device contains dedicated I/O functions for supporting DDR3 memory interfaces. The following
pinout rules must be followed to properly use the dedicated I/O functions.
• The DQS-DQ association rule must be followed.
– All associated DQs (8 or 4) to a DQS must be in the same DQS-12 group.
• A data mask (DM) must be part of the corresponding DQS-12 group.
– Example: DM[0] must be in the DQS-12 group that has DQ[7:0], DQS[0].
• A DQS pad must be allocated to a dedicated DQS True (+) pad.
– A DQS# pad is auto-placed when a differential SSTL type (SSTL15D) is selected.
• Do not assign any signal to a DQS# pad if SSTL15D is applied to the DQS pad.
– The software automatically places DQS# when SSTL15D is applied.
• DQS/DQS# pads cannot be used for other DDR functions.
– The DQS IOLOGIC structure is not compatible with non-DQS DDR IOLOGIC.
– Do not use DQS pads for any DDR3 signals except DQS and RST#. They can be used for other user logic
signals if a DDR function is not required.
• Data group signals (DQ, DQS, DM) must use the left and right sides of the LatticeECP3 device.
– Top-side pads do not have 2x gearing.
• Address, command, control and CK signals must be located on generic DDR-capable pads (ODDRXD).
– Place the CK/CK# outputs on the same side where the DQ and DQS pads are located. The top side is not
recommended for the high-speed DDR CK function.
– Place the address, command and control signals either on the same side as where the DQ and DQS pads
are located or on the top side. The bottom side cannot be used.
• RST# can be located anywhere an output is available as long as LVCMOS15 is applicable.
– All DDR3 signals except RST# use DDR functions.
• The DDR3 input reference clock to the PLL must be assigned to use dedicated clock routing.
– The dedicated PLL input pads are recommended while PCLK inputs can also be used.
– Two PLLs that have a direct connection to ECLK in each side can be used for a DDR3 function. (Note that
LatticeECP3-17EA devices have one PLL that supports DDR3 in each side.)
• Do not use the bottom-side pads in Bank 6 and Bank 3 for address, command and control signals.
– No generic DDR support on the bottom side of the device.
• VREF1 of the bank where the DQ, DQS and DM pads are located must not be taken by any signal.
– Do not PROHIBIT VREF1 in the preference file.
– VREF2 can be used for a general purpose I/O signal.
– Do not connect VREF1 and VREF2 together.
• Leave VTT pins unconnected when external VTT termination is implemented.12-86
LatticeECP3 High-Speed
I/O Interface
– VTT pins can be optionally connected to the external VTT source when a DDR3 interface is implemented
without external VTT termination. See the DDR3 Interface without Termination section for details.
– VTT pins can be connected in series with a capacitor (around .01uf) to ground when the bank has LVDS
internal termination to suppress externally generated common mode noise. Internal VTT termination cannot
be used in this case.
• It is required to provide a PCB connect resistor to the XRES pins. These pins cannot be used for other functions.
See TN1189, LatticeECP3 Hardware Checklist, for detailed requirements on the XRES pin.
Pin Placement Considerations for Improved Noise Immunity
In addition to the general pinout guidelines, there are additional pinout considerations for minimizing simultaneous
switching noise (SSN) impact. The following considerations are necessary to control SSN within the required level:
1. Properly terminated interface
2. SSN optimized PCB layout
3. SSN considered I/O pad assignment
4. Use of pseudo power pads
The guidelines listed below address the I/O pad assignment and pseudo power pad usage. Unlike the pinout guidelines, they are not absolute requirements. However, it is recommended that the pin placement follow the guidelines
as much as possible to increase the SSO/SSI noise immunity.
• Place the DQS groups for data implementation starting from the middle of the (right or left) edge of the
LatticeECP3. Allow a corner DQS group to be used as a data group only when necessary to implement the
required width.
• Locate a spacer DQS group between the data DQS groups if possible. A DQS group becomes a spacer DQS
group if the I/O pads inside the group are not used as data pads (DQ, DQS or DM).
– The pads in a spacer group can be used for address, command, control or CK pads as well as for user logic
or the pseudo power pads.
– No more than two consecutive-data DQS group placements is recommended in the middle of the edge.
When a corner-side DQS group is used for data, locate a spacer DQS group right next to it.
– If there is an incomplete DQS group (not the size of DQS-12) or enough space for more than 10 pads
between two DQS groups, the following DQS group can be located next to the previous complete DQS
group, both as data groups. The incomplete DQS groups, or the space between them, can be used as a
spacer.
• It is recommended that you locate a few pseudo VCCIO/ground (GND) pads inside a spacer DQS group. An I/O
pad becomes a pseudo power pad when it is configured to OUTPUT with its maximum driving strength (i.e.,
SSTL15, 10mA for DDR3) and connected to the external VCCIO or ground power source on the PCB.
– Your design needs to drive the pseudo power I/O pads according to the external connection. (i.e., you assign
them as OUTPUT and let your design drive ‘1’ for pseudo VCCIO pads and ‘0’ for pseudo GND pads in your
RTL coding.)
– Locating four pseudo power pads in a spacer DQS group should be sufficient to efficiently suppress the SSN
impact. At least two pseudo pads should be implemented in a spacer DQS group if more pins are needed for
a user design.
– Good candidate pads are two pads in both ends (the first and the last ones in the group) and/or two DQS
(positive and negative) pads in the middle.
• You may have one (DDR2/DDR3) or two (DDR/DDR2) remaining pads in a data DQS group which are not
assigned as a data pad in a DDR memory interface. Assign them to pseudo VCCIO or pseudo GND. The preferred location is in the middle of the group (right next to a DQS pad pair). Note that you may not have this extra
pad in DDR2/DDR3 if the DQS group includes a VREF pad for the bank.
• Avoid fast switching signals located close to the XRES pad of a LatticeECP3 device. XRES requires an external
resistor which is used to create the bias currents for the I/O. Since this resistor is used for a calibration reference 12-87
LatticeECP3 High-Speed
I/O Interface
for sensitive on-chip circuitry, careful pin assignment around the XRES pad is also necessary to produce less jittery PLL outputs for DDR memory interface operations.
The guidelines below are not as effective as the ones listed above. However, following them is still recommended to
improve the SSN immunity further:
• Assign the DM (data mask) pad in a data DQS group close to the other side of DQS pads where a pseudo power
pad is located. If the data DQS group includes VREF, locate DM to the other side of VREF with respect to DQS.
It can be used as an isolator due to its almost static nature in most applications.
• Other DQS groups (neither data nor spacer group) can be used for accommodating DDR3 address, command,
control and clock pads. It is recommended that you still assign all or most DQS pads (both positive and negative)
in these groups to pseudo power. Since LatticeECP3 DQS pads have a dedicated DDR function that cannot be
shared with other DDR3 signals, they are good pseudo power pad candidates.
• You can assign more unused I/O pads to pseudo power if you want to increase the SSN immunity. Note that the
SSN immunity does not get increased at the same rate as the increased number of pseudo power pads. The first
few pseudo power pad placements described above are more crucial. Keep the total pseudo power pad ratio
(VCCIO vs. GND) between 2:1 to 3:1.
• Although not necessary, it is slightly more effective to locate a pseudo VCCIO to a positive pad (A) and GND to a
negative pad (B) of a PIO pair if possible.
• If a bank includes unused input-only pads such as dedicated PLL input pads, you can also connect them to
VCCIO on your PCB. They are not as efficient as the pseudo power pads but can still be used as isolators, and
the connections on the board would provide good shielding. No extra consideration is necessary for these pins in
your design.
• It is a good idea to shield the VREF1 pad by locating pseudo power pads around it if the VREF1 pad is not
located in a data DQS group.
Table 12-14 shows the recommended examples of DQS group allocations following the guidelines. If you have
enough pin resources, following the best examples would provide you with maximized SSN immunity results. It is
more practical in most applications to follow the examples in the “Allowed” columns. It is expected that the SSN and
ground bounce impacts are considerably less than those cases where you do not include any consideration.

The DQSDLLB will generate the 90° phase shift required for the DQS signal. This primitive will implement the onchip DQSDLL. Only one DQSDLL should be instantiated for all the DDR implementations on one-half of the device.
The clock input to this DLL should be at the same frequency as the DDR interface. The DLL will generate the delay
based on this clock frequency and the update control input to this block. The DLL will update the dynamic delay
control to the DQS delay block when this update control (UDDCNTLN) input is asserted. Figure 12-70 shows the
primitive symbol. The active low signal on UDDCNTLN updates the DQS phase alignment.

DQSDLL Update Control
The DQS delay can be updated for PVT variation using the UDDCNTLN input. The DQSDEL is updated when the
UDDCNTLN is held low. The DDR memory controller or user logic can update DQSDEL when variations are
expected. It can be updated anytime except during a memory READ or WRITE operation.
It is important to understand that the UDDCNTLN signal is a synchronous input to the DQSDLL CLK domain.
When using DDR in 2x gearing, it is required to use clock domain transfer logic first to transfer UDDCNTLN from
slow clock domain to fast clock domain before it is input to DQSDLL. You can use two- or three-stage pipeline registers to safely transfer the DQSDEL update control input to the DQSDLL block. The first stage register uses the
local domain clock while the second and third registers use the DQSDLL CLK domain clock. The second to third
stage pipelining is desirable because it can eliminate the placement and routing issue due to the increased clock
rate (2x) for the net and also avoids any meta-stability issues.
DQSDLL Configuration
By default this DLL will generate a 90° phase shift for the DQS strobe based on the frequency of the input reference
clock to the DLL.
DQSBUF Logic Primitives for Generic DDR
The DQSBUF primitives (DQSBUFE and DQSBUFG for “E” devices) are used to generate the strobe logic and
delay used in the input DDR modules to correctly demux the DDR data. The DQSBUFE is used for x2 interfaces
and the DQSBUFG is used for x1 interfaces. The DQSBUFE1 is used only for output x2 interfaces in LatticeECP3
devices.
Figure 12-71 shows DQSBUF Generic DDR functions for the “E” and “EA” devices.

DQS Transition Detect
The DQS Transition Detect block inputs the fast ECLK and the slower SCLK (=1/2 ECLK) inputs and generates the
DDRCLKPOL and the DDRLAT signals. These signals are generated based on the phase of the FPGA SCLK at
the first ECLK transition. The DDRLAT signal is used in generic DDRX2 mode to transfer data from the ECLK to
SCLK domain. These are only required to implement generic DDR on the LatticeECP3 “E” devices. LatticeECP3
“EA” devices do not require these signals.
DDR Write Clock
This block inputs the fast edge clock used for the write side and generates two control signals, DQCLK0 and
DQCLK1. For Generic DDRX2 gearing, both DQCLK0 and DQCLK1 are generated. These control clocks run at a
rate of one-half the fast edge clock, and DQCLK1 is offset delayed by 90° relative to DQCLK0. DQCLK1 output
matches the phase of the SCLK input to the block. These two clocks toggle between different legs of a 4:1 mux in
the output logic, which allows 4:1 gearing of data at twice the edge clock rate. When using generic DDRX1, instead
of DDRX2 gearing, only the DQCLK1 is output, which toggles at the rate of FPGA clock provided by SCLK and
matches the phase of the SCLK input.
The DDR write clock block also inputs DYNDELPOL and DYNDELAY [6:0] delay inputs. These inputs support the
DDR3 memory interface to adjust delay among the various DQS groups. They can also be used for the generic
DDR for the same purpose. The DYNDELAY [6:0] can input 128 possible delay step settings with each step generating approximately 25ps nominal delay. In addition, the DYNDELPOL can be used to invert the clock for a 180°

DQSBUF Logic Primitives for DDR Memory Interfaces
The DQSBUF primitives (DQSBUFD and DQSBUFF) are used to generate the DQS strobe logic and delay used in
the input DDR modules to correctly demux the DDR data. The DQSBUF module used for the DDR memory interface is composed of DQS Delay, DQS Transition Detect, Data Valid Generation and the DDR Write Clock block, as
shown in Figure 12-77.

DQS Delay Block
The DQS Delay block receives the digital control delay line (DQSDEL) coming from one of the two DQSDLL blocks.
These control signals are used to delay the DQSI by 90°. ECLKDQSR is the delayed DQS and is connected to the
clock input of the first set of input DDR registers.
DQS Transition Detect
The DQS Transition Detect block generates the DDR Clock Polarity (DDRCLKPOL) and DDR Latch Control (DDRLAT) signal based on the phase of the FPGA clock (SCLK) and edge clock signal (ECLK) at the first DQS transition. The DDR READ control signal and FPGA CLK inputs to this block come from the FPGA core. The DDRLAT
signal is used when implementing DDRX2 output gearing to transfer data from the ECLK to SCLK domain.
Data Valid Module
The data valid module generates a DATAVALID signal. This signal indicates to the FPGA that valid data is transmitted out of the input DDR registers to the FPGA core.
DDR Write Clock
This block inputs the fast edge clock used for the write side and generates two control signals, DQCLK0 and
DQCLK1, and the clock used to generate the DQS clock (DQSW). DQSW is generated by applying the DQSDEL
from the DQSDLL to delay the ECLK (DDR3) or SCLK (DDR and DDR2) inputs. For the DDR3 memory interface
both DQCLK0 and DQCLK1 are generated. These control clocks run at a rate of one-half the edge clock, and

DQCLK1 is offset delayed by 90° relative to DQCLK0. These two clocks toggle between different legs of a 4:1 mux
allowing 4:1 gearing of data at twice the edge clock rate. When using output DDRX1 instead of DDRX2 gearing,
only the DQCLK1 is output, which is the same as the FPGA clock.
The DDR write clock block also inputs DYNDELPOL and DYNDELAY [6:0] delay inputs. These are used to support
the write leveling required for DDR3 memory interface. This delay can be used to adjust the delays among the DQS
groups to account for any skew that may be introduced due to the DDR3 fly-by topology.
The DYNDELAY [6:0] can input 128 possible delay step settings with each step generating approximately 26ps
nominal delay. In addition, the DYNDELPOL can be used to invert the clock for a 180° shift of the incoming clock.
The DYNDELAY [6:0] and DYNDELPOL inputs should be generated in the memory controller.

READ Pulse Generation
The READ signal to the DQSBUFF block is internally generated in the FPGA core. The READ signal will go high
after the READ command to control the DDR-SDRAM is initially asserted. This should normally precede the DQS
preamble by one cycle yet may overlap the trailing bits of a prior read cycle. The DQS Detect circuitry requires the
falling edge of the READ signal to be placed within the preamble stage.

Input DDR Primitives
The input DDR primitives represent the input DDR module used to capture both the generic DDR data and the
DDR data coming from a memory interface. There are two available modes for the DDR input registers, one is used
to implement DDRX1 gearing and the other is for DDRX2 gearing. The signals connected to the inputs of the IDDR
are different for the DDR memory interface.

This primitive implements the input register block in x1 gearing mode. This mode is used to implement DDR/DDR2
memory interfaces in the LatticeECP3 “E” and “EA” devices. It is also used to capture the generic DDRX1 data on
the LatticeECP3 “E” device.

This primitive is a simplified version of IDDRXD without the DDRCLKPOL and ECLKDQSR signal for the “EA”

On “EA” devices, the DDR registers use the primary clock (SCLK) only. The SCLK input should be connected to
the system (FPGA) clock. “EA” devices do not require the control signals from the DQSBUF module in the

This primitive is a simplified version of IDDRX2D without the DDRLAT, DDCLKPOL and the ECLKDQSR signals for
the LatticeECP3 “EA” devices. It is used for input generic DDRX2 input data in “EA” devices.
In this case, the first stage of registers is clocked by the ECLK signal and the second stage is clocked by the SCLK
signal. The “EA” device does not require the control signals from the DQSBUF module in the IDDRX2D1 element.

ECLKSYNCA is used in x2 gearing Tx interfaces to synchronize the signals generated from the ECLK after
RESET. These signals include the SCLK, DQCLK0/DQCLK1 and DQSW for DDR memory interfaces.
This module will STOP the ECLK to the CLKDIV and DQSBUF modules until the RESET is released.
Asserting the STOP input of the ECLKSYNC will stop the ECLK output. When the STOP signal is released, every
clock toggling from the second rising edge of the ECLK input will be output from this block. This block resides after
the muxes for edge clock sources and before driving onto the actual edge clock.

This will stop the ECLK to the CLKDIV and DQSBUF until after these blocks are out if reset. By doing this, the user
can synchronize the ECLK, SCLK and the DQCLKs used in the ODDR module.
It is required that there is at least two clock cycles between the release of RESET and the release of the STOP
input to ECLKSYNC. In the IPexpress-generated module, a soft IP consisting of two flip-flops is used to generate
this delayed STOP signal to ECLKSYNC. The reset input to the CLKDIV and DQSBUF is used as an input to these
two flip-flops. The clock input to these flip-flops must be slower than the ECLK.
Refer to the GDDRX2_TX.Aligned, GDDRX2_TX.DQSDLL.Centered and GDDRX2_TX.PLL.Centered interface
descriptions in the High-Speed DDR Interface Details section.
DELAYC
Data going to the DDR registers can be optionally delayed using the delay block. The DELAYC block is used to
compensate for clock injection delay times. The amount of the delay is determined by the software based on the
type of interface implemented using the Interface ID attribute IDDRAPPS. Refer to Interface ID Attribute section for
details. If an incorrect Interface ID is used for a given interface, then the DELAYC setting will be incorrect. It is
important that the correct Interface ID attribute be assigned for each interface to allow the software to set the correct value for DELAYC.

DELAYB
Data going to the DDR registers can also be delayed the DELAYB block. Unlike the DELAYC block where the software will control the amount of data delay, DELAYB block will allow user to control the amount of data delay. This
block receives 4-bit delay control. The 4-bit delay can be set by using static delay values or can be dynamically

controlled by the user logic. DELAYB can only be used when the interface type is dynamic. See the Building
Generic High-Speed Interfaces section for details.
The delay can be adjusted in 35ps steps. The user can choose from two types of delay values:
1. Dynamic – The delay value is controlled by the user logic using the inputs DEL[3:0] of the DELAYB block.
2. User-Defined – In this mode, the user chooses a static delay value from one of the 16 delay values. This
will tie the inputs DEL[3:0] of the DELAYB block to a fixed value depending on the value chosen.

Output DDR Primitives
The output DDR primitives represent the output DDR module used to generate both the generic DDR output data
and the DDR memory interface data. There are two available modes for DDR output registers. One is used to
implement DDRX1 gearing and the other for DDRX2 gearing.
ODDRXD
This primitive will implement the output register block in x1 gearing mode. This mode is used to implement
DDR/DDR2 memory interfaces on the “E” and “EA” devices. It is also used to generate the generic DDRX1 data on
“E” devices.

ODDRXD1
This element is used to generate the generic DDRX1 data on “EA” devices. The ODDRXD1 in the “EA” device does
not require the DQCLK1 control signal from the DQSBUF block. This makes the “EA” device more flexible for placement than “E” devices.

On the ODDRX2, it is required that the SCLK be in correct phase with DQCLK1 for the data to be captured correctly inside the ODDRX2. The figure below explains the correct relationship between the SCLK and DQCLK1.
SCLK edge must be delayed to occur after the DQCLK1 edge for the data to be captured without any glitches.
Figure 12-108. Correct DQCLK1 Polarity
Figure 12-109. Incorrect DQCLK1 Polarity
The soft IP, ECLKSYNCA, CLKDIVB, DQSBUFE1 and the SCLK routing delay will ensure the correct phase relationship between SCLK and DQCLK inside the ODDRX2 module. The user must generate the interface using IPexpress to guarantee this delay is achieved.

Interface ID Attribute
This attribute provides an ID setting for each of the high-speed interfaces in the LatticeECP3 “EA” device.
IDDRAPPS attribute is used for input interfaces and ODDRAPPS attribute is used for output interfaces. The value
for these is pre-determined for each high-speed DDR interfaces. These attributes will be set to the correct values
when the interfaces are generated by IPexpress. If an IDDRAPPS or ODDRAPPS attribute is not set for a given
interface, the software will error out. If an attribute value is not set correctly for a given interface, then the wrong
data delay is used in the DELAYC element for that interface.
The IDDRAPPS and ODDRAPPS attributes are strings. They are only generated for “EA” devices.

ISI Calibration
ISI correction is only available in the ODDRX2D or ODDRX2DQSA modes on the left and right sides of the device.
ISI calibration settings exist once per output, so each I/O in a DQS-12 group may have a different ISI calibration
setting.
The ISI Calibration is set using the ISI_CAL attribute. Table 12-38 shows the values that can be set for this attribute.
Table 12-38. ISI Calibration Attribute
The ISI block extends output signals at certain times, as a function of recent signal history, so it can be read at the
output signal’s destination. If the output pattern consists of long strings of 0s to long strings of 1s, there are no
delays on output signals. However, if there are quick, successive transitions from 010, the block will stretch out the
binary 1. This is because the long trail of 0s will cause these symbols to interfere with the logic 1. Likewise, if there
are quick, successive transitions from 101, the block will stretch out the binary 0.
This block is controlled by a 3-bit delay “stretching” control, set in the DQS logic section. There are eight settings in
the range from “BYPASS” to “DEL7”.

Migrating Designs from LatticeECP3 “E” to “EA”
This section lists the changes in design required when moving from LatticECP3 “E” device to an “EA” device. The
LatticeECP3-150EA device was designed as an “E” device in ispLEVER 7.2 SP2. So these changes will also be
required if moving a LatticeECP3-150EA design from ispLEVER 7.2 SP2 to ispLEVER 8.0 or later versions. It is
required that all LatticeECP3-150EA designs be implemented in ispLEVER 8.0 or newer software. Refer to the section Migrating Designs from ispLEVER 7.2 SP2 to ispLEVER 8.0 to see other changes required when you are moving designs from ispLEVER 7.2 SP2 to ispLEVER 8.0 or later versions of the software. The same changes will
apply if moving from ispLEVER 7.2 to the Lattice Diamond design software as well.
A summary of the differences between the “E” and “EA” devices are listed below:
• DDR x1 interfaces on “E” devices use ECLK (edge clock) as the clock input limiting the number of interfaces to 1
per side. DDR x1 interfaces on “EA” devices use the SCLK clock input, so you can have more than one interface
per side of the device.
• “E” device requires that DQSBUF be used to implement both x1 and x2 input and output DDR functions. “EA”
devices do not require the DQSBUF to implement the input and x1 output DDR functions. X2 output DDR functions will require the use of DQSBUF.
• The “E” devices require the data pins to be grouped into DQS groups so that every 10 data bits are locked to a
DQS group. This grouping is not required on the “EA” devices for inputs and 1x output interfaces. 2x output interfaces on “EA” would require DQS grouping.
• The primitives used for Generic DDR input and output functions are different between “E” and “EA”.
• All “EA” designs require that the IDDRAPPS/ODDRAPPS be assigned to each interface which is not required on
the “E” device. Refer to the section Interface ID Attribute for a description of this attribute. IPexpress-generated
modules will contain this attribute.
• In DDR and DDR2 memory, the implementation will mostly be same between “E” and “EA” devices. But since
DDR and DDR2 use generic DDR to generate the output CLKP/CLKN signal, these must use new primitives on
the “EA” device. In addition, all the primitives require the IDDRAPPS/ODDRAPPS attributes to be added for the
“EA” device.
Refer to the section DDR Software Primitives and Attributes for a detailed description of the primitives. Table 12-39
lists the clocking differences between “E” and “EA” devices for each interface. Table 12-40 lists the differences in
library elements used for each interfaces. Refer to the High-Speed DDR Interface Details section for block diagrams of each of the interfaces in the tables below.

Due to the differences described above, some of the “E” interfaces must be regenerated in the software as an “EA”

Migrating Designs from ispLEVER 7.2 SP2 to ispLEVER 8.0
This section lists changes that need to be made to existing designs when migrating from ispLEVER 7.2 SP2 to ispLEVER 8.0 and later versions of the software. The same changes will apply if moving from ispLEVER 7.2 to the
Lattice Diamond design software as well.
LatticeECP3-70E and LatticeECP3-90E designs:
• No HDL changes are required to move the LatticeECP3 “E” generic designs from ispLEVER 7.2 SP2 to ispLEVER 8.0
• It is required to re-run the designs through the software Map, Place and Route. ispLEVER 8.0 has an added
Design Rule Check that will flag any general non-dedicated routed used on clock paths to DDR interfaces.
• If any of these errors occur, they must be fixed by either changing the clock pin assignment to a dedicated pin or
by adding preferences to route the clock on dedicated clock routes.
• All the interface rules and placement guidelines specified for the interface must be followed.
LatticeECP3-150EA designs:
• All “EA” designs were implemented as “E” designs in ispLEVER 7.2 SP2. All “EA” generic DDR designs will have
to be regenerated when moving over to ispLEVER 8.0 except for the designs using DQS interfaces.
• The requirements listed in the section Migrating Designs from LatticeECP3 “E” to “EA” should be followed when
moving “EA” designs from ispLEVER 7.2 SP2 to ispLEVER 8.0.
• All modules should be regenerated using IPexpress.
• “EA” designs require that an Interface ID attribute, IDDRAPPS or ODDRAPPS, be added to all the IDDR and
ODDR elements to indicate the interface topology being used. The software will error out if it does not see this
attribute on the DDR elements. These attributes are added automatically when IPexpress is used to generate the
interface.
Other important migration rules:
• All DDR designs must only use one of the pre-defined topologies listed in this technical note.
• All DDR interfaces must be generated using the IPexpress software tool.

• This technical note must be strictly followed to understand the interface rules, placement guidelines and timing
analysis for all interfaces.
• ispLEVER 7.2 SP2 allows the use of either the DELAYB or DELAYC element to delay the incoming data. In ispLEVER 8.0, all non-dynamic interfaces must only use the DELAYC element to delay the data input. DELAYB can
only be used only for dynamic interfaces.
• A new Interface ID attribute IDDRAPPS and ODDRAPPS is required for “EA” devices. The software uses this
attribute to determine the delay settings to be programmed into the DELAYC element. Refer to the DDR Software
Primitives and Attributes section for the values to be used for this attribute. In ispLEVER 8.0 the software will
error out if this attribute is not assigned for “EA” devices. “E” devices do not require this attribute.
• It is required that clocks connected to the DDR registers only use dedicated clock resources. No general routing
should be used on these clocks. A new DRC check was added to ispLEVER 8.0 Place and Route that will generate an error message if the clocks to any of the DDR elements are not using a dedicated clock route. This check
will also generate an error message if the clock going to the PLL/DLL that is generating the DDR clocks is not
using a dedicated route. As a result, you may see designs passing all DRC checks in ispLEVER 7.2 SP2 fail in
ispLEVER 8.0. It is recommended that this problem be fixed by changing either clock location or adding preferences to reroute the clock using a dedicated clock route.

Appendix A. Building DDR Interfaces Using IPexpress in ispLEVER 7.2 SP2
This appendix describes the interface generation for DDR Generic and DDR Memory using IPexpress in ispLEVER
7.2 SP2. It is highly recommended to update your software to the latest version. This appendix is only for reference.
IPexpress can be used to configure and generate the DDR Memory Interface and Generic DDR Module. The tool
will generate an HDL module that will contain the DDR primitives. This module can be used in the top-level design.
To implement the correct clocking structures to be used for high-speed source synchronous interfaces, see the
High-Speed DDR Interface Details section.
Figure 12-117 shows the main window of IPexpress. The DDR_Generic and DDR_MEM options are under Architecture.

The implementation for several of the interfaces described above differs between the “E” and “EA” devices. Refer to
the High-Speed DDR Interface Details section to see implementation details for “E” and “EA” devices.
The Data Delay setting for each interface is predetermined and cannot be changed by the user. User can only control Data Delay values when using a dynamic interface.
Note: Some modules generated by IPexpress have a SCLK and ECLK output port. If present, this port must be
used to drive logic outside the interface driven by the same signal. In these modules, the input buffer for the clock is
inside the IPexpress module and therefore cannot be used to drive other logic in the top level.

Introduction
Configuration is the process of loading or programming a design into volatile memory of an SRAM-based FPGA.
This is accomplished via a bitstream file, representing the logical states, that is loaded into the FPGA internal configuration SRAM memory. The functional operation of the device after programming is determined by these internal
configuration RAM settings. The SRAM cells must be loaded with configuration data each time the device powers
up.
The configuration memory in LatticeECP3™ FPGAs is built using volatile SRAM; therefore, an external non-volatile
configuration memory is required to maintain the configuration data when the power is removed. This non-volatile
memory supplies the configuration data to the LatticeECP3 when it powers up or anytime the device needs to be
updated.
To support multiple configuration options the LatticeECP3 supports the Lattice sysCONFIG™ interface as well as
the dedicated JTAG port. The available configuration options, or modes, are listed in Table 15-1.
Table 15-1. Supported Configuration Modes
This technical note covers all of the configuration options available for LatticeECP3.
The LatticeECP3 configuration RAM can be loaded in a number of different modes. In these configuration modes,
the FPGA can act as a master, a peripheral to a CPU, or a slave of other system devices. It also supports in-system
configuration via the JTAG port.
The decision about which configuration mode to use is a system design concern. There are many methods for configuring the FPGA utilizing four basic schemes.
• Master: As a master, the FPGA is the source of the clock, and accesses an external PROM or EPROM storage
device through a serial connection, with no additional timing or control signals used. This scheme includes Serial
Programming Interface (SPI) that supports a seamless connection for programming using industry-standard
external Flash-based memory devices.
• Slave: In slave mode the FPGA receives bit-serial or byte-wide data and a clock from an external data and timing
source, either from a microprocessor, or from the lead device in an FPGA-daisy chain. As a slave device, the
clock used to configure the FPGA is generated externally and provided to the CCLK input.

• JTAG: The device can be configured through the JTAG port. The JTAG port is always on and available regardless of the configuration mode selected.
The system designer should determine the requirements for configuration very early in the design. Many factors
must be considered when deciding which configuration mode is best suited for the design. The flexible features
for configuration can provide a seamless design to the system.
General Configuration Flow
The LatticeECP3 enters Configuration mode when one of three things happens: power is applied to the device, the
PROGRAMN pin is driven low, or a JTAG or SSPI Refresh instruction is issued. Upon entering Configuration mode
the INITN pin and the DONE pin are driven low to indicate that the device is initializing (i.e. getting ready to receive
configuration data).
Once initialization is complete, the INITN pin will be driven high. The low-to-high transition of the INITN pin causes
the CFG pins to be sampled, telling the LatticeECP3 which port it will configure from. The LatticeECP3 then begins
reading data from the selected port and starts looking for the preamble header (BDB3 hex for unencrypted bitstreams, and BAB3 for encrypted bitstreams). All data after the preamble is valid configuration data.
When the LatticeECP3 has finished reading all of the configuration data, and assuming there have been no errors,
the DONE pin goes high and the LatticeECP3 enters user mode. In other words, the device begins to function
according to your design.
Note that the LatticeECP3 may also be programmed via JTAG. When programming via JTAG, the INITN and DONE
signals have no meaning, because JTAG, per the IEEE standard, takes complete control of all device I/Os. It is recommended that the PROGRAMN input be held high when using the JTAG port to configure the FPGA. This prevents the FPGA SRAM memory from being cleared when the JTAG programming cycle is complete.
The following sections define each configuration pin, each configuration mode, and all of the configuration options
for the LatticeECP3.
Configuration Pins
The LatticeECP3 supports two types of configuration pins, dedicated and dual-purpose. The dedicated pins are
used exclusively for configuration; the dual-purpose pins, when configuration is complete, are available as extra I/O
pins. If a dual-purpose pin is to be used both for configuration and as a general purpose I/O (GPIO) the following
conditions must be met:
• The I/O type must remain the same. For example, if the pin is a 3.3V CMOS pin (LVCMOS33) during configuration, it must remain a 3.3V CMOS pin as a GPIO.
• You must select the correct CONFIG_MODE setting and set the PERSISTENT attribute to OFF. Doing so permits the dual-purpose sysCONFIG pins to be used as GPIO when configuration completes. These settings can
be found in the ispLEVER®
Design Planner or Spreadsheet View in Lattice Diamond™ design software. See
Table 15-3 for more information.
• You are responsible for insuring that no internal or external logic will interfere with the control signals required by
configuration mode you have selected.
The dual-purpose configuration pins are controlled using HDL source file attributes, or with the ispLEVER or Diamond Preference Editor. You can read about how to apply HDL preferences in TN1177, LatticeECP3 sysIO Usage
Guide.
The LatticeECP3 also supports JTAG for configuration, transparent read back, and JTAG testing. The following
sections describe the function of the various sysCONFIG and JTAG pins. Table 15-2 is provided for reference.15-3

LatticeECP3 sysCONFIG Usage Guide
Configuration Process and Flow
Prior to becoming operational, the FPGA goes through a sequence of states, including initialization, configuration
and wake-up.
Figure 15-1. Configuration Flow
Power-up Sequence
In order for the LatticeECP3 to operate, power must be applied to the device. During a short period of time, as the
voltages applied to the system rise, the FPGA will have an indeterminate state. Other devices in the system will
also be in an indeterminate state.
As power continues to ramp, a Power On Reset (POR) circuit inside the FPGA becomes active. The POR circuit,
once active, makes sure the external I/O pins are in a high-impedance state. It also monitors the VCCcore, VCCaux,
and the VCCIO8 input rails. The POR circuit waits for the following conditions:
• VCCcore > 0.8V
• VCCaux > 2.7V
• VCCIO8 > 0.8V (Supply used for configuration I/O)
Power not stable PROGRAMN must not be asserted low
until after all power rails have reached
stable operation.
PROGRAMN must not make a falling edge
transition during the time the FPGA is in the
Initialization state. PROGRAMN must be asserted
for a minimum low period of tPRGMRJ in order for
it to be recognized by the FPGA. Failure to meet this
requirement can cause the device to become
non-operational, requiring power to be cycled.

LatticeECP3 sysCONFIG Usage Guide
When these conditions are met the POR circuit releases an internal reset strobe, allowing the device to begin its
initialization process. The FPGA samples the CFG[2:0] input pins to determine if a master or a slave mode configuration is selected. The FPGA uses this information to determine the tICFG initialization period. The next step is to
assert INITN active low, and to drive DONE low. When INITN and DONE are asserted low the device moves to the
initialization state, as shown in Figure 15-1.
The PROGRAMN input must not be asserted low as power is applied to the FPGA. Nor should it be allowed to transition from high to low at any time that INITN is in the initialization state.
Figure 15-2. Configuration from Power-On-Reset Timing
Initialization
The LatticeECP3 enters the memory initialization phase immediately after the Power On Reset circuit drives the
INITN and DONE status pins low. The purpose of the initialization state is to clear all of the SRAM memory inside
the FPGA.
The FPGA remains in the initialization state until all of the following conditions are met:
• The tICFG time period has elapsed
• The PROGRAMN pin is deasserted
• The INITN pin is no longer asserted low by an external master
The dedicated INITN pin provides two functions during the initialization phase. The first is to indicate the FPGA is
currently clearing its configuration SRAM. The second is to act as an input preventing the transition from the initialization state to the configuration state.
During the tICFG time period the FPGA is clearing the configuration SRAM. When the LatticeECP3 is part of a chain
of devices each device will have different tICFG initialization times. The FPGA with the slowest tICFG parameter can
prevent other devices in the chain from starting to configure. Premature release of the INITN in a multi-device chain
may cause configuration of one or more chained devices to fail to configure intermittently.
The active-low, open-drain initialization signal INITN must be pulled high by an external resistor when initialization
is complete. To synchronize the configuration of multiple FPGAs, one or more INITN pins should be wire-ANDed. If
one or more FPGAs or an external device holds INITN low, the FPGA remains in the initialization state.
Loading the Configuration Memory
The rising edge of the INITN pin causes the FPGA to enter the configuration state. The FPGA is able to accept the
configuration bitstream created by the ispLEVER and Diamond development tools.
If the FPGA CFG[2:0] input pins have placed it in a master configuration mode it will begin fetching data from an
external non-volatile memory.
If the FPGA CFG[2:0] input pins have placed it in a slave configuration mode, the FPGA waits for configuration data
to be presented to it on each CCLK rising edge.

LatticeECP3 sysCONFIG Usage Guide
During the time the FPGA receives its configuration data the INITN control pin takes on its final function. INITN is
used to indicate an error exists in the configuration data. When INITN is active high configuration is proceeding
without issue. If INITN is asserted low, an error has occurred and the FPGA will not operate.
Wake-up
Wake-up is the transition from configuration mode to functional mode. Wake-up starts when the device has correctly received all of its configuration data. When all configuration data is received, the FPGA asserts an internal
DONE strobe. The assertion of the internal DONE causes a Wake Up state machine to run that sequences four
controls. The four control strobes are:
• External DONE
• Global Write Disable (GWDISn)
• Global Output Enable (GOE)
• Global Set/Reset (GSR)
External DONE is a bi-directional, open-drain I/O. The FPGA releases the open-drain DONE pin at the programmed wake-up phase. If an external agent is holding the external DONE pin low, the wake-up process of the
LatticeECP3 does not proceed. Only after the external DONE is active high do the final wake-up phases complete.
Once the final wake-up phases are complete, the FPGA enters user mode.
The Global Output Enable, when it is asserted, permits the FPGA’s I/O to exit a high-impedance state and take on
their programmed output function. The FPGA inputs are always active. However, they are typically prevented from
performing any action on the FPGA logic by the assertion of the Global Set/Reset (GSR).
The Global Set/Reset is an internal strobe that, when asserted, causes all I/O/LUT flip-flops, distributed RAM output flip-flops, and Embedded Block RAM output flip-flops that have the GSR enabled attribute to be set/cleared per
their HDL definition.
The Global Write Disable is a control that overrides the write enable strobe for all RAM logic inside the FPGA. The
inputs on the FPGA are always active, as mentioned in the Global Output Enable section. Keeping GWDIS
asserted prevents accidental corruption of the instantiated RAM resources inside the FPGA.
Clearing the Configuration Memory and Re-initialization
Several methods are available to clear the internal configuration memory of the LatticeECP3 device. The first is
mentioned earlier when the device powers up (see the “Power-up Sequence” section of this document). A second
method is to toggle the PROGRAMN pin. Also, JTAG can reinitialize the memory through an ISC Refresh command. SSPI can also initiate a reconfiguration with the Refresh command.
The other methods available are:
• Assertion of the PROGRAMn dedicated input
• Sending the ISC Refresh command using a configuration port (JTAG, or Slave SPI)
Invoking one of these methods causes the LatticeECP3 to drive INITN and DONE low. The FPGA enters the initialization state described above.
FPGA Configuration Control Pin Definitions
The LatticeECP3 FPGA provides a set of I/O pins that can be used to load a configuration bitstream into the
device. Some of these I/O are single purpose and are always available to perform configuration operations. Those
configuration pins that are not dedicated can be configured for your use after the FPGA has entered user mode.
This section describes what each I/O is, how it functions, and how to reclaim some for your own use.15-7
LatticeECP3 sysCONFIG Usage Guide
Configuration Pin Management
The dual-purpose sysCONFIG pins described in the Table 15-2 are dedicated configuration pins during the device
configuration process. The PERSISTENT attribute is used to determine whether the dual-purpose sysCONFIG
pins remain sysCONFIG pins during normal operation. The LatticeECP3 provides three settings for the PERSISTENT feature. The available options are shown in Table 15-3.
Table 15-3. PERSISTENT Setting and Affected Pins
You can use the SLAVE_PARALLEL or the Slave SPI configuration port to access some of the resources connected to the FPGA. Accessing the FPGA resources requires special command sequences, which are described in
other documents.
Dedicated Control Pins
The LatticeECP3 makes a set of dedicated control pins available to allow you to select the way you want to configure the FPGA. The following sub-sections describe the LatticeECP3 dedicated sysCONFIG pins. These pins are
powered by VCCIO8.
While the device is under IEEE 1149.1 or 1532 JTAG control the dedicated programming pins have no meaning.
This is because a boundary scan cell will control each pin, per JTAG 1149.1, rather than normal internal logic.
JTAG Pins
The JTAG pins are standard IEEE 1149.1 TAP (Test Access Port) pins. The JTAG pins are dedicated pins and are
always accessible when the LatticeECP3 device is powered up. While the device is under 1149.1 or 1532 JTAG
control the dedicated programming pins INITN, DONE, and CCLK have no meaning. This is because a boundary
scan cell will control each pin, per the IEEE standard, rather than normal internal logic. If the device is being
accessed by JTAG then PROGRAMN will still be an active input even in JTAG mode.
These pins are powered by VCCJ.
TDO
The Test Data Output pin is used to shift out serial test instructions and data. When TDO is not being driven by the
internal circuitry, the pin will be in a high impedance state. This pin should be wired to TDO of the JTAG connector,
or to TDI of a downstream device in a JTAG chain. An internal pull-up resistor on the TDO pin is provided. The
internal resistor is pulled up to VCCJ.
TDI
The Test Data Input pin is used to shift in serial test instructions and data. This pin should be wired to TDI of the
JTAG connector, or to TDO of an upstream device in a JTAG chain. An internal pull-up resistor on the TDI pin is
provided. The internal resistor is pulled up to VCCJ.
TMS
The Test Mode Select pin controls test operations on the TAP controller. On the falling edge of TCK, depending on
the state of TMS, a transition will be made in the TAP controller state machine. An internal pull-up resistor on the
TMS pin is provided. The internal resistor is pulled up to VCCJ.

LatticeECP3 sysCONFIG Usage Guide
TCK
The test clock pin, TCK, provides the clock to run the TAP controller state machine, which loads and unloads the
JTAG data and instruction registers. TCK can be stopped in either the high or low state and can be clocked at frequencies up to that indicated in the LatticeECP3 Family Data Sheet. The TCK pin supports hysterisis; the typical
hysterisis is approximately 100mV when VCCJ = 3.3V. The TCK pin does not have a pull-up. A pull-down resistor
between TCK and ground on the PCB of 4.7 K is recommended to avoid inadvertent clocking of the TAP controller
as VCC ramps up.
Optional TRST
Test Reset, TRST, is not supported on the LatticeECP3.
V
CCJ
Having a separate JTAG VCC (VCCJ) pin lets you apply a voltage level to the JTAG port that is independent from the
rest of the device. Valid voltage levels are 3.3V, 2.5V, 1.8V, 1.5V, and 1.2V, but the voltage used must match the
other voltages in the JTAG chain. VCCJ must be connected even if JTAG is not used.
Please see In-System Programming Design Guidelines for ispJTAG Devices for further JTAG chain information.
Configuration and JTAG Pin Physical Description
All of the sysCONFIG dedicated and dual-purpose pins are part of Bank 8. Bank 8 VCCIO determines the output
voltage level of these pins, input thresholds are determined by the I/O Type selected in the ispLEVER Design Planner (default is 3.3V LVCMOS) and Diamond Spreadsheet View.
JTAG voltage levels and thresholds are determined by the VCCJ pin, allowing the LatticeECP3 to accommodate
JTAG chain voltages from 1.2V to 3.3V.
CFG[2:0]
The Configuration Mode pins, CFG[2:0], are used to inform the FPGA how you want to configure the device. The
actions performed by the remaining configuration pins depend on the state of the CFG[2:0] inputs. The CFG[2:0]
input pins have weak internal pull-up resistors, that guarantee a valid configuration mode is selected should they be
left unconnected. Lattice recommends the CFG pins be connected with independent pull-up/pull-down resistors. It
is also recommended that these pins not be directly connected to the power or ground planes.
The CFG[2:0] pins are sampled at two different points in the configuration process. The first sample point is when
the Power-On Reset state machine starts up. The POR sample point determines if the FPGA to be configured in
master or slave mode. The tICFG time period changes based on this information.
The second time the CFG pins are sampled is at the rising edge of the INITN pin. This sample is used to make the
final configuration selection. Table 15-4 describes the configuration mode that is active based on the CFG input
pins. The state on the CFG pins at any other time is not important. The state pins can be changed freely, which
may be useful for selecting a new configuration mode.

LatticeECP3 sysCONFIG Usage Guide
PROGRAMN
The PROGRAMn is a dedicated input that is used to configure the FPGA. The PROGRAMn pin is a falling edge
sensitive, and has an internal weak pull-up. When a falling edge occurs, the FPGA exits user mode and starts a
device configuration sequence at the Initialization phase, as described earlier.
Proper operation of the LatticeECP3 FPGA depends on the PROGRAMn pin. The following conditions must be
met:
• The PROGRAMn pin must not be asserted until after all of the supply rails are stable. This can be achieved by
either placing an external pullup resistor and tying it to the VCCIO8 voltage, or permitting the FPGA's internal
pull-up resistor to pull the input high.
• The PROGRAMn pin must make a high to low transition in order to cause the FPGA to enter configuration mode.
This is not necessary when first powering the FPGA, as the FPGA will enter configuration mode after the internal
Power On Reset circuit releases the internal reset.
• The PROGRAMn pin must not be allowed to transition from high to low at any time INITn is active (i.e. low) as a
result of being in the Initialization state.
• PROGRAMn must meet the minimum active pulse width tPRGMRJ.
• PROGRAMn remains an active input even when the JTAG bus is being used to program the FPGA. The PROGRAMn pin should not be asserted during JTAG programming sequences.
Failing to follow these guidelines may prevent the FPGA from operating.
PROGRAMn must be de-asseted in order for the FPGA to exit the Initialization state.
Figure 15-3. Configuration from PROGRAMN Timing
INITN
The INITn pin is a bidirectional open-drain control pin. It has the following functions:
• After power is applied, or after a PROGRAMn assertion it goes low to indicate the FPGA configuration cells are
being erased. The low time assertion is specified with the tICFG parameter.
• After the tICFG time period has elapsed the INITn pin is deasserted (i.e. is active high) to indicate the FPGA is
ready for its configuration bits. In master mode the FPGA starts loading bits from an attached non-volatile memory. In slave mode the FPGA waits for the bits to arrive over the interface selected by the CFG[2:0] input pins.
The rising edge of the INITn samples the CFG[2:0] inputs, allowing the FPGA to determine how it is to be configured.
• INITn can be asserted low by an external agent before the tICFG time period has elapsed in order to prevent the
FPGA from reading configuration bits. This is useful when there are multiple FPGA's chained together. The
FPGA with the longest tICFG time can hold all other FPGA's in the chain from starting to get data until it is ready
itself.

• The last function provided by INITn is to signal an error during the time configuration data is being read. Once
t
ICFG has elapsed, and the INITn pin has gone high, any INITn assertion signals the FPGA has detected an error
during configuration.
The following conditions will cause INITN to become active, indicating the Initialization state is active:
• Power has just been applied
• PROGRAMN falling edge occurred
• The IEEE 1532 Refresh command has been sent using a slave configuration port (JTAG, SSPI, etc.).
If the INITN pin is asserted due to an error condition, the error can be cleared by correcting the configuration bitstream and forcing the FPGA into the Initialization state.
Figure 15-4. Configuration Error Notification
DONE
The DONE pin is a dedicated bi-directional open drain with a weak pull-up that signals the FPGA is in User mode.
DONE is first able to indicate entry into User mode only after the internal DONE pin is asserted. The intenal DONE
signal defines the beginning of the FPGA Wake-Up state.
The DONE output pin is controlled by the DONE_EX configuration parameter. The default state of this pin is OFF.
The default mode causes the LatticeECP3 to start immediately after the internal DONE bit is asserted. The FPGA
does not stall waiting for the DONE pin to be asserted high.
The FPGA can be held from entering User mode indefinitely by having an external agent keep the DONE pin
asserted low. In order to use DONE to stall entering user mode the DONE_EX configuration preference must be
set ON. A common reason for keeping DONE driven low is to allow multiple FPGAs to be completely configured.
As each FPGA reaches the DONE state, it is ready to begin operation. The last FPGA to configure can cause all
FPGAs to start in unison.
It is critical that DONE be asserted low when the LatticeECP3 is in a chain of FPGAs. The LatticeECP3 continues
to pass configuration clock pulses to FPGAs attached downstream as long as DONE is de-assserted. Any FPGA
permitted to assert DONE and enter User mode will only pass a few hundred more configuration clock cycles.
Downstream FPGAs will never complete their configuration process if this occurs.
The DONE pin drives low in tandem with the INITN pin when the FPGA enters Initialization mode. As described
earlier, this condition happens when power is applied, PROGRAMN is asserted, or an IEEE 1532 Refresh command is received via a slave configuration port.
Sampling the DONE pin is a good way for an external device to tell if the FPGA has finished configuration. However, when using IEEE 1532 JTAG to configure SRAM the DONE pin is driven by a boundary scan cell, so the state
of the DONE pin has no meaning during IEEE 1532 JTAG configuration (once configuration is complete, DONE
takes on the behavior defined by the DONE_EX configuration parameter).
Configuration Clock (CCLK)

slave configuration modes is selected by the CFG[2:0] inputs.

LatticeECP3 sysCONFIG Usage Guide
Please refer to the LatticeECP3 AC Timing information in the LatticeECP3 Family Data Sheet for information about
maximum clock rates, and data setup and hold parameters.
When the LatticeECP3 is in a chain of FPGAs it is necessary to continue to drive CCLK until all of the FPGAs have
received their configuration data. It is recommended the CCLK continue to be toggled until the DONE signal is
active.
Dual-Purpose sysCONFIG Pins
The Dual-Purpose sysCONFIG pins, depending on the configuration mode selected by the CFG[2:0] input pins,
provide special configuration functions during the Configuration phase of the device wake-up process. The dualpurpose pins can be recovered for your use once the FPGA enters User mode. Successful recovery of the dualpurpose pins relies on following the guidelines described in the “Configuration Pins” section of this document.
The dual-purpose configuration pins are located in the same I/O bank as the dedicated configuration pins. The
configuration pins in the LatticeECP3 are powered by the VCCIO8 voltage rail.
Master Clock (MCLK)
The MCLK provides a reference clock for synchronous non-volatile memories attached to the FPGA. MCLK is only
active when the FPGA CFG[2:0] inputs select a master configuration mode. See Table 15-4 for a full description of
the available configuration modes selectable by the CFG[2:0] input pins. MCLK acts as a general purpose I/O if the
FPGA is in a slave configuration mode.
The LatticeECP3 generates MCLK from an internal oscillator. The initial output frequency of the MCLK is approximately 2.5MHz. The MCLK frequency can be altered using the MCCLK_FREQ parameter. You can select the
MCCLK_FREQ using the Diamond Spreadsheet View. For a complete list of the supported MCLK frequencies, see
Table 15-8.
During the initial stages of device configuration the frequency value specified using MCCLK_FREQ is loaded into
the FPGA. Once the FPGA accepts the new MCLK_FREQ value the MCLK output begins driving the selected frequency. Make certain that when selecting the MCLK_FREQ that you do not exceed the frequency specification of
your configuration memory, or of your PCB. Lattice recommends reviewing the LatticeECP3 AC specifications in
the LatticeECP3 Family Data Sheet when making MCLK_FREQ decisions.
The LatticeECP3 provides the ability to be configured from a bitstream that is encrypted. There are additional
requirements on the MCCLK_FREQ selection that you must adhere to when configuring the LatticeECP3 with an
encrypted bitstream. These conditions are discussed in the “Bitstream Encryption/Decryption Flow” section of this
document.
DI/CSSPI0N
The DI/CSSPI0N configuration pin provides one of two functions depending on the FPGA’s configuration mode.
When the FPGA is in Serial Configuration Mode the pin is set to DI (Data Input) mode. When the FPGA is in SPI
Master or SPI Master Multiboot mode, the pin is set to CSSPI0N (Chip Select SPI 0).
When the FPGA is in Serial Configuration Mode the DI pin receives incoming configuration data. See the Serial
Configuration Mode section of this document for more information.
When the FPGA is in SPI Master or SPI Master Multiboot mode the CSSPI0N is the chip select strobe to the
attached SPI memory that contains the FPGA’s configuration bits. The FPGA asserts this pin active low during the
Configuration phase of the wake-up process.
An external pull-up resistor is required on CSSPI0N in SPI and SPIm modes of operation. Some SPI memory
devices require the CSn input to rise in tandem with their input voltage. The internal pull-up on CSSPI0N does not
become active until the FPGA determines all input voltage rails are stable. This does not meet the requirements of
some SPI memory vendors.15-12
LatticeECP3 sysCONFIG Usage Guide
DOUT/CSON
The DOUT/CSON configuration pin is used only when placing the LatticeECP3 into a chain of FPGAs requiring
configuration.
The DOUT/CSON pin is an output from the LatticeECP3 and is only active when the FPGA is connected to another
FPGA in a daisy chain.
When in a daisy chain, the pin may act as either a data output (DOUT) or a chip select (CSON). The behavior is
described in detail in the Configuring Multiple FPGA Devices section of this document.
For serial and parallel configuration modes, when Bypass mode is selected, this pin becomes DOUT (see
Figure 15-10). When the device is fully configured a Bypass instruction in the bitstream is executed and the data on
DI, or D[0:7] in the case of a parallel configuration mode, will then be routed to the DOUT pin. This allows data to
be passed, serially, to the next device. In a parallel configuration mode D0 will be shifted out first followed by D1,
D2, and so on.
Daisy chaining the Parallel devices can be implemented with the Flowthrough attribute. This attribute allows the
CSON pin to be driven when the done bit is set and configuration of the first part is complete. The CSON of the first
part will drive the CSN of the second part.
You will find this attribute in the ispLEVER Generate Bitstream Data property under Chain Mode or in the Diamond
Bitstream options window. See Appendix B for more information on setting these options in Diamond.
The DOUT/CSON drives out a high on power-up and will continue to do so until the execution of the Bypass
instruction within the bitstream, or until the I/O Type is changed by your code.
CSN/SN
The CSN/SN is a bidirectional pin that is active in Slave Parallel Configuration mode, or in Slave SPI mode. The pin
is a chip select that gates the incoming configuration data.
Detailed information about using the chip select pin can be found in the “Slave Parallel Mode (SPCM)” and “Slave
SPI (SSPI)” configuration sections of this document.
CS1N/HOLDN
The CS1N/HOLDN configuration pin is active only in Slave Parallel Configuration mode or in Slave SPI mode.
When the LatticeECP3 is in a Slave Parallel Configuration mode the pin acts as a chip select that works in conjunction with CSN. Information detailing the interaction of these two pins is described in the Parallel Configuration mode
section of this document.
The configuration pin takes on the HOLDN function when the LatticeECP3 is in Slave SPI Configuration mode.
Assertion of the HOLDN input causes the FPGA to ignore the SPI SCLK. Details for using HOLDN are provided in
the Slave SPI Configuration section.
When CSN or CS1N is high, the D[0:7], and BUSY pins are tri-stated. CSN and CS1N are interchangeable when
controlling the D[0:7], and BUSY pins.
WRITEN
The WRITEN configuration pin is an input pin that is active in Slave Parallel Configuration mode. It is a write enable
strobe that controls the direction data flows on the D[0:7] data bus pins. When WRITEN is asserted active low the
FPGA D[0:7] pins are tri-stated to allow an external bus master to write data into the FPGA.
BUSY/SISPI
The BUSY/SISPI configuration pin is active in Slave Parallel Configuration mode and in SPI Master modes.
When the LatticeECP3 is in a Slave Parallel Configuration mode, the pin is a tri-state output pin. When the FPGA
parallel bus is active due to the assertion of CSN/CS1N the BUSY pin indicates the FPGA’s ability to accept a byte
of configuration data. The FPGA is able to accept another configuration byte when this output is driven low.15-13
LatticeECP3 sysCONFIG Usage Guide
When the LatticeECP3 is in SPI Master mode the pin is connected to the data input of the SPI PROM that contains
the configuration data. SISPI is an output used by the LatticeECP3 to transmit commands to the SPI PROM.
D[0]/SPIFASTN
The D[0]/SPIFASTN configuration pin is available in Slave Parallel Configuration and SPI Master configuration
modes.
In Slave Parallel Configuration mode the D[0] pin is the most-significant data bit in the combined D[0:7] parallel
data bus.
In SPI Master configuration modes it becomes the SPIFASTN input. The input is sampled at the rising edge of the
INITN output.
The SPIFASTN selects the Read Opcode transmitted to the SPI PROM. When SPIFASTN is deasserted (i.e.
driven to Vih) the FPGA requests a Read Operation using the 03 hex Read Opcode. When SPIFASTN is asserted
(i.e. driven to Vil) the FPGA requests a Read Operation using the 0B hex Read Opcode. A SPI PROM that accepts
the 0B Read Opcode is able to operate at higher serial clock rates. Consult the SPI memory vendor’s data sheet for
the exact capabilities of the SPI memory device.
Do not leave this input floating when a SPI Master mode is selected.
In parallel mode this pin is D[0] and operates in the same way as D[1:6] below. Taken together D[0:7] form the parallel data bus, D[0] is the most significant bit in the byte. The D[0:7] data bus are open-drain I/O without a pullup
resistor during the time that power is applied to the FPGA. They also remain in this state until the FPGA is fully configured. When the FPGA is configured the D[0:7] I/O take on the attributes defined in your HDL source code, or
using the Spreadsheet View preference editor.
As with D[1:6], if SRAM (configuration memory) needs to be accessed using the parallel pins while the part is in
user mode (the DONE pin is high) then the PERSISTENT control cell must be set to preserve this pin as D[0]. Note
that SRAM may only be read using JTAG or Slave Parallel mode.
D[1], D[2], D[5] and D[6]
These configuration pins are only available in Slave Parallel Configuration mode and are intermediary data bits for
the parallel data bus made up of bits D[0:7].
Remember that D[0] is the most-significant data bit and D[7] is the least-significant.
D[3]/SI
The D[3]/SI configuration pin is only available in Slave Parallel Configuration or in Slave SPI Configuration mode.
When the LatticeECP3 is in Slave Parallel Configuration mode the pin acts as D[3].
In Slave SPI Configuration mode the pin acts as the Serial Input pin for data supplied by a SPI Master Controller.
D[4]/SO
The D[4]/SO configuration pin is only available in Slave Parallel Configuration or in Slave SPI Configuraiton mode.
When the LatticeECP3 is in Slave Parallel Configuration mode the pin acts as D[4].
In Slave SPI Configuration mode the pin acts as the Serial Output pin for data transmitted from the FPGA back to
the SPI Master Controller.
D[7]/SPID0
The D[7]/SPID0 configuration pin is only available in Slave Parallel Configuration or in Master SPI Configuration
mode.
When the LatticeECP3 is in Slave Parallel Configuration mode the pin acts as D[7]. This is the least-significant-bit
of the D[0:7] data bus.15-14
LatticeECP3 sysCONFIG Usage Guide
In Master SPI Configuration mode the pin acts as the SPI Data Input pin receiving data from an attached SPI
PROM.
Configuration Modes
LatticeECP3 devices support many different configuration modes, utilizing either serial or parallel data paths. The
configuration method used by the LatticeECP3 is selected by driving the CFG[2:0] input pins. The CFG[2:0] input
pins are sampled at the falling edge of INITN to determine if the part is in a master or a slave configuration mode.
The pins are sampled a second time at the rising edge of INITN to determine the specific configuration mode.
The LatticeECP3 starts the configuration process in one of three ways:
• Initial application of power
• Assertion of the PROGRAMN input pin
• Reception of a REFRESH command form a configuration port (JTAG, Slave SPI, Slave Parallel)
SPI Interface
The Serial Peripheral Interface (SPI) is a four-wire de facto bus standard used to transmit and receive serial data.
The LatticeECP3 can use a SPI data bus to retrieve its configuration data from most SPI ROMs.
The amount of ROM storage required depends on the number of Look Up Tables (LUTs) in the LatticeECP3 device
you have selected. Figure 15-5 shows how many bits of configuration data are required for each member of the
LatticeECP3 family.
Table 15-5. Maximum Configuration Bits – SPI Flash Mode Bitstream File1
The estimated configuration time can be calculated by dividing the bitstream size (in bits) from Table 15-5 by the
configuration clock (MCLK or CCLK) frequency. The MCLK frequency is modified using the Global Preferences tab
within the Diamond Spreadsheet View or in the ispLEVER Design Planner.
The LatticeECP3 provides the following three SPI configuration modes:
• SPI Master (SPI)
• SPI Master Multiboot (SPIm)
• Slave SPI (SSPI)
SPI Master Mode
The simplest SPI configuration consists of one SPI Serial Flash connected to one LatticeECP3, as shown in
Figure 15-5. In this configuration the LatticeECP3 is the master of the SPI bus. The FPGA controls the chip select
and the MCLK, and receives the configuration data on the SPID0 input.
During FPGA configuration the SISPI output sends a command sequence to reset the SPI PROM’s internal
address pointer. The SPIFASTN informs the FPGA which SPI Read Command to send to the SPI PROM. When

LatticeECP3 sysCONFIG Usage Guide
the SPIFASTN input is driven high, the FPGA sends a 03 Hex Read Opcode. When it is asserted active low, the
FPGA sends a 0B Hex Read Opcode to the SPI PROM.
As mentioned in the section describing the MCLK behavior, the configuration clock frequency can be altered. The
MCLK frequency must not exceed the clock input frequency of the SPI PROM.
Figure 15-5. One FPGA, One SPI Serial Flash
In order to configure properly, the LatticeECP3 must transmit at least 128 clock pulses before it receives the preamble code (BDB3 hex for unencrypted bitstreams, and BAB3 for encrypted bitstreams). It is required that the data in
the SPI PROM be padded to account for these extra clocks. The bitstream generation tool automatically adds the
necessary padding information.
SPI Master Multiboot (SPIm) Mode
SPI Master Multiboot mode is an enhancement to the SPI Master boot mode. The SPI memory is attached to the
FPGA in exactly the same way as SPI Master mode. SPIm enables you to partition the SPI PROM to store two configuration bitstreams. The FPGA will attempt to configure from the Primary image, and if the FPGA fails to configure from the primary image it tries to load a fail-safe Golden bitstream. Figure 15-6 shows the concept from a high
level.

Figure 15-6. SPIm Mode for Dual-Boot Capability
Internally, SPIm mode adds logic to detect a configuration failure and the ability to reattempt configuration from a
different address within the SPI Flash device. While SPI mode treats the SPI Flash device as a single block of storage starting at address zero, SPIm mode allows segmentation of the Flash device for the golden bitstream.
In SPIm mode, the primary bitstream is stored at address offset 0x010000. When configuring, the LatticeECP3
device automatically reads the data beginning at this address first. If after 2*14 clocks the device still does not
receive the pre-amble code or a bitstream error is encountered after receiving the pre-amble code, the configuration logic resets and loads the data located at address offset 0xFFFF00.
The LatticeECP3 uses a 24-bit addressing scheme to access the SPI memory array. The amount of storage
remaining in the SPI starting at address 0xFFFF00 is only 256 bytes. This is not enough to store a complete
LatticeECP3 configuration bitstream. The LatticeECP3 configuration bitstream is stored elsewhere in the SPI
PROM. The data retrieved by the FPGA at address 0xFFFF00 is an instruction pointing to the start of the failsafe
configuration data.
An example of the SPI Flash memory organization for SPIm mode is shown in Table 15-6.

Slave SPI (SSPI)
The LatticeECP3 can be configured by a SPI Master controller. Using the CFG[2:0] inputs to select SSPI configuration mode the FPGA becomes a SPI Slave device, receiving data from a SPI Master controller. The FPGA can be
accessed using Mode 0 and Mode 3 bus transactions.
The slave SPI interface allows for a the following functions to be performed:
• Configuration of the FPGA
• Readback of the FPGA configuration bitstream
• Forcing the device to REFRESH as if PROGRAMN were asserted
• Read/Write access to a SPI PROM attached to the SPI Master configuration pins
• Clearing the FPGA configuration
• Reading the FPGA ID code
• Reading the FPGA User ID code

LatticeECP3 sysCONFIG Usage Guide
Table 15-7. Slave SPI Pins
The chip select pin (SN) is a chip select input to the FPGA. The LatticeECP3 responds on the falling and rising
edges of the SN input. SN is not a level sensitive input. When the SN falling edge occurs the FPGA is ready to
accept commands from a SPI Master Controller. A rising edge on the SN input resets the internal state machine
and tri-states the SO output pin. The only exception to this is when the FPGA has received a SPI_PROGRAM command. This command can only be interrupted by the assertion of the PROGRAMN input.
The HOLDN pin is provided to allow a SPI Master Controller to pause transactions on the Slave SPI port. When
HOLDN is asserted low the FPGA tri-states the SO output and ignores the SCLK input. This allows the SPI Master
Controller to interact with another SPI device and then resume transactions to the LatticeECP3. Encrypted bitstreams must be sent without interruption. You are not permitted to assert HOLDN or deassert SN once an
encrypted bitstream transmission has begun.
Figure 15-7. Slave SPI Example
Figure 15-7 illustrates how an on-board CPU can be connected to the LatticeECP3 using the Slave SPI programming interface. The CPU can fetch configuration data from the attached SPI PROM. The CPU is not required to deassert the SN input to the FPGA. When the CPU asserts the CS1N to access the SPI PROM the FPGA HOLDN is
asserted causing it to ignore SCLK transitions. The HOLDN input can not be asserted when transferring an
encrypted bitstream.
Full details on using Slave SPI mode on the LatticeECP3 are provided in TN1222, LatticeECP3 Slave SPI Port
User’s Guide.
Slave Serial Configuration Mode (SCM)
Slave Serial Configuration mode provides a simple, low pin count method for configuring one or more FPGAs. Data
is presented to the FPGA on the Data Input pin DI at every CCLK rising edge.

Figure 15-8. Slave Serial Block Diagram
The bitstream data generated by Lattice Diamond is formatted so that it is ready to shift into the FPGA. Left shift
the data out of the file in order for it to be correctly received by the FPGA.
The FPGA synchronizes itself on either a 0xBDB3 or 0xBAB3 code word. It is critical that any data presented on
DIN not be recognized as one of these two synchronization words early. To guarantee proper recognition of the
synchronization word it is recommended that the synchronization word always be preceded by a minimum of 128
‘1’ bits. Presenting any other bitstream data, Programmer generated header information for example, risks the
being misinterpreted due to bit slippage.
Slave Serial Configuration Mode can be used to configure a chain of FPGAs. Details about configuring a chain of
devices is discussed in “Combining Configuration Modes” on page 36 of this document.
Slave Parallel Mode (SPCM)
The LatticeECP3 can be configured using Slave Parallel Configuration Mode. Slave Parallel permits an external
master to configure the FPGA using an 8-bit synchronous SRAM bus interface. Slave Parallel Configuration Mode
is a flexible method for configuring one or more FPGAs. It is also the fastest mode available for configuring the
LatticeECP3.
The slave parallel interface allows for a multitude of different functions to be performed:
• Configuration of the FPGA
• Readback of the FPGA configuration bitstream
• Reading the device CRC
• Reading the programming status register
• Reading the FPGA ID code
• Reading the FPGA User ID code

Figure 15-9. Slave Parallel Block Diagram
Figure 15-9 shows the typical Slave Parallel Configuration Mode usage. Configuration data can be written to the
LatticeECP3 immediately following the INITN rising edge. The LatticeECP3 data bus bit ordering is denoted using
a big-endian nomenclature. This means that D0 receives the MSBit, and D7 receives the LSBit. One byte of data
can be sent to the FPGA on each rising CCLK edge as long as CSN, CS1N, and WRITEN are asserted. When the
LatticeECP3 is the only device being configured the FPGA can receive configuration data at the full CCLK rate.
The master device is not required to monitor the BUSY pin in this situation, because the configuration bitstreams
are padded to avoid BUSY assertion.
Sending an encrypted bitstream must be done atomically, i.e. without interruption. The bus master is not permitted
to pause the transfer of an encrypted bitstream by deasserting the CSN or CS1N inputs. The CCLK pin can be
stretched or stopped if desired, but the CSN and CS1N pins must remain asserted.
Slave Parallel mode can also be to read status registers and the configuration bitstream. In order for the Slave Parallel port to be used to perform read operations the FPGA must have the PERSISTENT preference set to
SLAVE_PARALLEL mode. See the Configuration Pin Management section of this document for more information.

LatticeECP3 sysCONFIG Usage Guide
LatticeECP3 only requires the four IEEE 1149.1 control signals (TCK, TMS, TDI, and TDO) in order to initiate and
complete programming operations. The LatticeECP3 JTAG port is always available for use, regardless of the configuration mode selected.
Programming the LatticeECP3 using the JTAG port is typically accomplished in one of several ways:
• You can use Lattice Diamond Programmer software in combination with a Lattice download cable
• You can use Automatic Test Equipment that can read Serial Vector Format (SVF), In-System Configuration (ISC),
STAPL/JAM, or ATE vector files
• You can use an embedded microprocessor to run Lattice's ispVM Embedded configuration software
Lattice Diamond Programmer’s Fast Program
The Lattice Diamond development tools translate your design into a bitstream containing an optional header, mandatory preamble, and the device configuration data. The configuration data includes its own preamble, fuse data,
and finally a trailing CRC. This basic structure is used for all of the configuration modes supported by the
LatticeECP3. The IEEE 1532 mode adds some additional operations to the device configuration process.
Prior to sending the configuration data the FPGA’s Boundary Scan I/O Cells are placed in a high-impedance state,
and the FPGA’s configuration memory is cleared. Because the I/O are tri-stated the DONE and INITn output signals do not provide status information while the configuration data is being written to the FPGA. The JTAG configuration mode uses an internal status register to confirm the FPGA DONE and INITn status signals indicate the
device configured correctly. After the internal DONE and INITn controls are confirmed, the Boundary Scan I/O
Cells are re-enabled, and all I/O take on the function assigned to them.
The JTAG interface, because it can control the Boundary Scan I/O Cells, can also be used to configure the
LatticeECP3 without putting the I/O into a high-impedance state. During device configuration the I/O cells can be
locked in their last known active state. This mode of operation is called TransFR Programming. A full description of
how to use TransFR is provided in TN1087, Minimizing System Interruption During Configuration Using TransFR
Technology.
JTAG Configuration Data Read and Save
The JTAG interface can be used to read the configuration data stored in the FPGA’s SRAM array. There are two
modes available to retrieve the data, foreground mode or background mode.
Foreground readback is accessed using IEEE 1532 mode. When using this method the JTAG Boundary Scan Cells
are placed in a high-impedance state, and the configuration data read. Once the configuration data is retrieved the
Boundary Scan Cells are restored, and the FPGA returns to normal operation.
The Background Read and Save operation allows you to read the content of the device while the device remains in
operation. All I/O, as well at the non-JTAG configuration pins, continue normal operation during the Background
Read and Save operation. You must not violate the following conditions when using the Background Read and
Save function:
• The Soft Error Detection system must not be running. De-assert the SEDENABLE pin to prevent the SED circuit
from interfering with the Background Read and Save operation. It is recommended that you wait at least one full
SEDSTART to SEDDONE time period after the deassertion of the SEDENABLE to make sure the SED circuit
has discontinued operation. Alternately monitor the SEDINPROG output, and wait for it to de-assert.
• Write operations to distributed RAM blocks must be suspended. Write operations that occur at the same time the
SRAM cell is being read are non-deterministic. It is possible for the SRAM to receive, or retain, incorrect RAM
data.
Regardless of which read and save mode is used the configuration data will not include the EBR or the distributed
RAM contents. Distributed RAM contents will always be return zeroes.15-22
LatticeECP3 sysCONFIG Usage Guide
Boundary Scan and Boundary Scan Description Language (BSDL) Files
The LatticeECP3, as mentioned previously, provides an IEEE 1149.1 compliant JTAG interface. The JTAG interface
can be controlled by Automatic Test Equipment (ATE) that uses Boundary Scan Description Language (BSDL)
files. Lattice makes BSDL files available for the LatticeECP3 on the Lattice Semiconductor website.
The boundary scan ring covers all of the I/O pins, as well as the dedicated and dual-purpose sysCONFIG pins.
Note that PROGRAMN, CCLK, and the CFG pins are observe only (BC4, JTAG read-only) boundary scan cells.
When performing JTAG 1149.1 EXTEST instructions, the SERDES CML termination for both Tx and Rx is set to 50
ohm pull-ups. This allows the high-speed channels to operate properly if DC data is sent or received. During JTAG
EXTEST, the termination will be set to 50 ohm. This overrides the termination resistance programmed into the
SERDES logic.
Bitstream Generation Software Usage
This section describes the settings for bitstream generation performed by the Diamond software program that generates a bitstream. These options are controlled through the Global Preferences of the Diamond Spreadsheet View
and the property settings of the Bit Generation Software tool. To set the Global Preferences and properties in Diamond, see Appendix B. By setting the proper parameter in the Lattice design software the selected configuration
options are set in the generated bitstream. As the bitstream is loaded into the device the selected configuration
options take effect. These options are described in the following sections.
Bit Generation takes a fully routed Physical Design (.ncd file) as input and produces a configuration bitstream (bit
images). The bitstream file contains all of the configuration information from the Physical Design defining the internal logic and interconnections of the FPGA, as well as device-specific information from other files associated with
the target device. The data in the bitstream can then be downloaded directly into the FPGA memory cells or used
to generate files for PROM programming (using a separate program, ispVM). Please refer to the ispVM documentation for details on creating PROM image files.
Configuration Options
Several configuration options are available for each configuration mode. These options are controlled from the
Spreadsheet View for each Strategy. They include the following items.
• When daisy chaining multiple FPGA devices an overflow option is provided for serial and parallel configuration
modes
• When using SPI or SPIm mode, the master clock frequency can be set
• A security bit can be set to prevent SRAM readback
• The Persistent option can be set
• Configuration pins can be protected
• DONE pin options can be selected
By setting the proper parameter in the Lattice design software the selected configuration options are set in the generated bitstream. As the bitstream is loaded into the device the selected configuration options take effect. These
options are described in the following sections.
Master Clock
If the CFG pins indicate an SPI or SPIm mode, the MCLK pin will become an output with a default frequency, or
one selected when you added preferences to your design. The default Master Clock Frequency is 2.5 MHz. For a
complete list of the supported Master Clock frequencies, please see the LatticeECP3 Family Data Sheet. When
using the LatticeECP3 devices, the available frequencies are restricted, as shown in the data sheet.
You can change the Master Clock frequency by setting the MCCLK_FREQ global preference in the Diamond
Spreadsheet view tool. During configuration one of the first pieces of information loaded is the MCCLK_FREQ 15-23
LatticeECP3 sysCONFIG Usage Guide
parameter. When this parameter is loaded the master clock frequency changes to the selected value without glitching. Care should be exercised not to exceed the frequency specification of the slave devices or the signal integrity
capabilities of the PCB layout.
Configuration time is computed by dividing the maximum number of configuration bits, as given in Table 15-5
above, by the Master Clock frequency.
Table 15-8. Selectable Master Clock (MCCLK) Frequencies During Configuration (Nominal)
Security Bit
Setting the CONFIG_SECURE option to ON prevents readback of the SRAM from JTAG or the sysCONFIG pins.
When CONFIG_SECURE is set to ON the only operations available are erase and write. The security control bit is
updated as the last operation of SRAM configuration. If a secured device is read it will output all ones.
For LatticeECP3 devices the CONFIG_SECURE option is accessed via the Design Planner in ispLEVER. To set
this option in Diamond, see Appendix B. The default is OFF.
Persistent Option
The PERSISTENT option is used to direct the place and route tools about how it can use the sysCONFIG pins. By
default the PERSISTENT option is turned OFF, which allows the place and route tools to reclaim most of the configuration pins as general purpose input/output. Changing the PERSISTENT configuration option from its default
state prevents the place and route tools from either the Slave SPI or the Slave Parallel configuration ports from
becoming general purpose I/O.
Enabling the dedicated sysCONFIG ports is useful for performing additional capabilities while the FPGA is in user
mode.
You use the SLAVE_PARALLEL setting when:
• You want to read back the FPGAs SRAM contents. The LatticeECP3 provides a command set and access protocol that allows the configuration SRAM to be read from the FPGA. The Slave Parallel port can read all of the configuration data, except the EBR and the distributed RAM contents.
• You have a LatticeECP3, configured as a SPI Master, in series of FPGAs in a device chain. The SPI Master
FPGA must keep the MCLK pin active in order to provide a configuration clock for all of the chained FPGAs.
Table 15-3 describes the configuration pins that are preserved. The MCLK output is only preserved Slave Parallel configuration mode. If PERSISTENT is set to OFF, or SSPI the MCLK output tri-states after the lead FPGA is
configured, which prevents chained FPGAs from configuring.
Use the SSPI PERSISTENT setting when:
• You want to access a SPI PROM attached to the SPI Master configuration pins. You can attach a SPI memory
controller and using a custom command you can perform erase, program, and verify sequences on the SPI
PROM while the FPGA is in operation. Table 15-3 describes the configuration pins that are preserved. InformaMCCLK (MHz) MCCLK (MHz)

tion about the Slave SPI transactions are published in TN1222 LatticeECP3 Slave SPI Port User's Guide. You
can also use the SSPI Embedded device programming software provided by Lattice.
Configuration Mode
The CONFIG_MODE option tells the software which configuration port the hardware is using to program the
FPGA. Setting this parameter permits the design software to check to make sure configuration port pins are not
oversubscribed. The oversubscription is only flagged as a warning. In some cases it is acceptable to oversubscribe
the configuration port. For example it is acceptable to have the FPGA in SPI Master configuration mode and use
the SISPI, SPID0,a nd SPICS pins as general purpose I/O.
The CONFIG_MODE is also used to make sure encrypted bitstreams are generated correctly. To guarantee correct
operation of encrypted bitstreams you need to set the CONFIG_MODE parameter.

During configuration the DONE output pin is low. Once configuration is complete, indicated by assertion of an internal DONE bit, the device wake-up sequence takes place. The external DONE pin is able to operate in one of two
modes during the wake up sequence. The default behavior, set when DONE_EX = OFF, is for it to actively drive to
VIL. When DONE_EX is set ON, the external DONE pin becomes an open-drain output. The LatticeECP3 wake up
sequence will stall until the external DONE pin is pulled high. Set DONE_EX to ON when you want to synchronize
the when a chain of FPGAs wakes up. Make sure you place a pullup resistor that is able to drive all of the DONE
pins.
Device Wake-Up
When configuration is complete the device will wake up in a predictable fashion. Wake-Up occurs after successful
configuration, without errors, and provides the transition from Configuration Mode to User Mode. The Wake-Up process begins when the internal DONE bit is set.
Table 15-9 provides a list of the Wake-Up sequences supported by the LatticeECP3; Figure 15-11 shows the
Wake-Up timing. The default Wake-Up sequence works fine for most single device applications.

Synchronizing Wake-Up
The LatticeECP3 is, in most cases, configured using one of the master configuration modes. The FPGA, when in
master configuration mode, is driving the configuration clock. The configuration clock is used for stepping through
the final four Wake-Up states described in the previous section.
The LatticeECP3 has the ability to use an external clock source to control the final state transitions in the Wake_Up
process. There are three possible sources for the clock. The JTAG TCK, the Slave Configuration CCLK, and a general-purpose input.
Start_Up Clock Selection
Once the FPGA is configured, it enters the start-up state, which is the transition between the configuration and
operational states. This sequence is synchronized to a clock source, which defaults to CCLK when a slave configuration mode is used, or TCK when JTAG is used.
If desired, a user-defined clock source can be used instead of CCLK/TCK. You need to specify this clock signal,
and instantiate the STRTUP library element in your design. The example shown below shows the proper syntax of
instantiating the STRTUP library element.

Synchronous to Internal DONE Bit
If the LatticeECP3 is the only device in the configuration chain, or the last device in the chain, DONE_EX should be
set to the default value (OFF). The Wake-Up process will be initiated by setting of the internal DONE bit on successful completion of configuration.
Synchronous to External DONE Pin
The DONE pin can be used to synchronize Wake-Up to other devices in a configuration chain. If DONE_EX (see
the DONE EX section above) is ON then the DONE pin is an open-drain bi-directional pin. If an external device
drives the DONE pin low then the Wake-Up sequence stalls until DONE is active high. Once the DONE pin goes
high the device will follow the selected WAKE_UP sequence.
In a configuration chain, a chain of devices configuring from one source (such as Figure 15-17), it is usually desirable, or even necessary, to delay wake-up of all of the devices until the last device finishes configuration. This is
accomplished by setting DONE_EX to OFF on the last device while setting DONE_EX to ON for the other devices.
Wake-up Sequence Options
The wake-up sequence options determine the order of application for three internal signals, GSR, GWDIS, and
GOE, and one external signal, DONE.
• GSR is used to set and reset the core of the device. GSR is asserted (low) during configuration and de-asserted
(high) in the Wake-Up sequence.
• When the GWDIS signal is low it safeguards the integrity of the RAM Blocks and LUTs in the device. This signal
is low before the device wakes up. The GWDIS signal is internal to the FPGA, and does not appear on any FPGA
I/O. During the time it is driven low all EBR and LUT RAM elements are safe from being modified.
• During initialization and configuration the FPGA I/O are placed in a high impedance state. The GOE control controls when the FPGA I/O leave the high impedance state. The I/O are Hi-Z when GOE is asserted low.
• The DONE pin, when high, indicates that FPGA has completed configuration and is in user mode. DONE will
only be high if DONE_EX=ON, the output driver is released, and the external pin is pulled up.
If DONE_EX (see DONE EX above) is OFF then sequence 21 is the default, but you can select any sequence from
8 to 25; if DONE_EX is ON the default sequence is 4, but you can select any sequence from 1 to 7.
WAKE_ON_LOCK
The wake-up sequence can be delayed until the selected PLLs have a chance to lock. The WAKE_ON_LOCK attribute selects which PLLs will delay the wake-up sequence until the PLL locks. If you choose an external signal for
PLL feedback rather than an internal clock signal, wake-up must occur without waiting for PLL lock because all I/Os
are tri-stated until the device wakes up, preventing the PLL from locking.
Using the default mode of operation, the device PLLs do not have to be locked for wake-up to commence. You can
choose to make the wake-up sequence dependent on any of the PLLs. If multiple PLLs are included in the design,
all PLLs in the design have to be locked to satisfy the wake-up sequence.15-27

Bitstream Generation Property Options
Run DRC (T/F)
When the Run DRC option is set to TRUE, a physical design rule check will be run prior to generating a bitstream.
The output will be saved to the Bit Generation report (.bgn file). Running DRC before a bitstream is produced will
detect any errors that could cause the FPGA to function improperly. If no fatal errors are detected, it will produce a
bitstream file. The default is True and will run DRC. When this option is set to False, a design rule check (DRC) will
not be run prior to generating a bitstream.
Create Bitfile (T/F)
This option allows you to decide whether or not to generate an output bitstream. The default setting is to create a
bitstream.
Bitstream File Formats
• Bit file (binary)
• Raw bit file
• Mask & Readback file (ASCII)
• Mask & Readback file (binary)
These options allow you to chose the format of a bitstream file. The Raw Bit option causes the Bitstream Generator
to create a Raw Bit (.rbt) file instead of a binary file (.bit). A binary .bit file can be viewed with a binary editor.
The Raw Bit File is a text file containing ASCII ones and zeros representing the bits in the bitstream file. If you are
using a microprocessor to configure a single FPGA, you can include the Raw Bit file in the source code as a text file
to represent the configuration data. The sequence of characters in the Raw Bit file is the same as the bit sequence
that will be written into the FPGA. This file is a large file.
A Mask file (.msk) can be generated in either an ASCII formatted file or binary file. The Mask file is used to compare relevant bit locations for executing a readback of configuration data contained in an operating FPGA. You can
compare readback data from the device to the mask file after downloading the bitstream. The ASCII mask file will
contain 1’s and 0’s, and X’s. The file contains all FPGA data frames. It contains no header, ID frames, address
frames and no preloaded frames.
No Header (T/F)
The generated bitstream contains no header. The default will be false and will always produce a bitstream file
including all the header information.
Bitstream Encryption/Decryption Flow
The LatticeECP3 supports both encrypted and non-encrypted bitstreams. The encrypted flow adds only two steps
to the normal FPGA design flow, encryption of the configuration bitstream and programming the encryption key into
the LatticeECP3 devices.
Encrypting the Bitstream
As with any other Lattice FPGA design flow, the engineer must first create the design using a device and version of
ispLEVER or Diamond which supports the encryption feature. You must obtain the Encryption Installer from Lattice
prior to using Encryption capabilities. The design is synthesized, mapped, placed and routed, and verified. Once
the engineer is satisfied with the design a bitstream is created and loaded into the FPGA for final debug. After the
design has been debugged it is time to secure the design.
The bitstream can be encrypted using an appropriate version of ispLEVER by going to the Tools pull-down menu
and selecting Security features or by using the Universal File Writer (UFW), which is part of the Lattice ispVM™ 15-28
LatticeECP3 sysCONFIG Usage Guide
System tool suite. The file is encrypted using ispVM as follows. To encrypt the bitstream in Diamond, see Appendix
B.
Figure 15-12. ispVM Main Window
1. Start ispVM. You can start ispVM from the Tools menu in ispLEVER or from the Start -> Programs menu
in Windows. ispVM is not accessible from the Tools menu in Diamond. You should see a window that looks
similar to Figure 15-12. Click on the UFW button on the toolbar. You will see a window similar to Figure 15-
13.

2. Double click on Input Data File and browse to the non-encrypted bitstream created using ispLEVER or
Diamond. Double-click on Output Data File and select an output file name. Right-click on Encryption and
select ON. Right-click on Configuration Mode and select the type of device the FPGA will be configuring
from, such as SPI Serial Flash. Right-click on Encryption Key and select Edit Encryption Key. You will
see a window that looks similar to Figure 15-14.15-29
LatticeECP3 sysCONFIG Usage Guide
Figure 15-14. Encryption Key Dialog Window
3. Enter the desired 128-bit key. The key can be entered in Hexadecimal or ASCII. Hex supports 0 through f
and is not case sensitive. ASCII supports all alphanumeric characters, as well as spaces, and is case sensitive. Note: be sure to remember this key. Lattice cannot recover an encrypted file if the key is lost. Click
on OK to go back to the main UFW window.
4. From the menu bar, click on Project -> Generate to create the encrypted bitstream file.
5. The bitstream can now be loaded directly into non-volatile configuration storage (such as SPI Serial Flash)
using a Lattice ispDOWNLOAD®
Cable, a third-party programmer, or any other method normally used to
program a non-encrypted bitstream. However, before the LatticeECP3 can configure from the encrypted
file the 128-bit key used to encrypt the file must be programmed into the one-time programmable cells on
the FPGA.
Programming the 128-bit Key
The next step is to program the 128-bit encryption key into the one-time programmable cells on the LatticeECP3.
This is done through the device JTAG interface. Note that this step is separated from file encryption to allow flexibility in the manufacturing flow. For instance, the board manufacturer might program the encrypted file into the SPI
Serial Flash, but the key might be programmed at your facility. This flow adds to design security and it allows you to
control over-building of a design. Over-building occurs when a third party builds more boards than are authorized
and sells them to grey market customers. If the key is programmed at the factory, then the factory controls the number of working boards that enter the market. The LatticeECP3 will only configure from a file that has been
encrypted with the same 128-bit key that is programmed into the FPGA.
To program the key into the LatticeECP3, proceed as follows.
1. Attach a Lattice ispDOWNLOAD cable from a PC to the JTAG connector wired to the LatticeECP3 (note
that the 128-bit key can only be programmed into the LatticeECP3 using the JTAG port). Apply power to
the board.
2. Start the ispVM System software. ispVM can be started from within the ispLEVER Tools menu or from the
Start -> Programs menu in Windows. ispVM cannot be invoked from the Tools menu in Diamond. You
should see a window that looks similar to Figure 15-12. If the window does not show the board’s JTAG
chain then proceed as follows. Otherwise, proceed to step 3.
a. Click the SCAN button in the toolbar to find all Lattice devices in the JTAG chain. The chain shown
in Figure 15-12 has only one device, the LatticeECP3. 15-30
LatticeECP3 sysCONFIG Usage Guide

3. Double-click on the line in the chain containing the LatticeECP3. This will open the Device Information window (see Figure 15-17). From the Device Access Options drop-down box select Security Mode, then click
on the Security Key button to the right. The window will look similar to Figure 15-16.
Figure 15-16. Enter the Encryption Key15-31
LatticeECP3 sysCONFIG Usage Guide
4. Enter the desired 128-bit key. The key can be entered in Hexadecimal or ASCII. Hex supports 0 through f
and is not case sensitive. ASCII supports all alphanumeric characters, as well as spaces, and is case sensitive. This key must be the same as the key used to encrypt the bitstream. The LatticeECP3 will only configure from an encrypted file whose encryption key matches the one loaded into the FPGA’s one-time
programmable cells. Note: be sure to remember this key. Once the Key Lock is programmed, Lattice Semiconductor cannot read back the one-time programmable key.
a. The key can be saved to a file using the Save to File button. The key will be encrypted using an 8-
character password that you select. The name of the file will be .bek. In the future,
instead of entering the 128-bit key, simply click on Load from File and provide the password.
5. Programming the Key Lock secures the 128-bit encryption key. Once the Key Lock is programmed and the
device is power cycled, the 128-bit encryption key cannot be read out of the device. When satisfied, type
Yes to confirm, then click Apply.
6. From the main ispVM window (Figure 15-12) click on the green GO button on the toolbar to program the
key into the LatticeECP3 one-time programmable cells. When complete, the LatticeECP3 will only configure from a bitstream encrypted with a key that exactly matches the one just programmed.
Verifying a Configuration
As an additional security step when an encrypted bitstream is used, the readback path from the SRAM fabric is
automatically blocked. In this case, for all ports, a read operation will produce all 1's. However, even when the configuration bitstream has been encrypted and readback disabled, there are still ways to verify that the bitstream was
successfully downloaded into the FPGA.
If the SRAM fabric is programmed directly, the data is first decrypted and then the FPGA performs a cyclic redundancy code (CRC) on the data. (CRC) circuitry is used to validate each configuration data frame (sequence of data
bits) as it is loaded into the target device. If all CRCs pass, configuration was successful. If a CRC does not pass,
the DONE pin will stay low and INITN will go from high to low.
If the encrypted data is stored in non-volatile configuration memory, such as SPI Serial Flash, the data is stored
encrypted. A bit-for-bit verify can be performed between the encrypted configuration file and the stored data.
File Formats
The base binary file format is the same for all non-encrypted, non-1532 configuration modes. Different file types
(hex, binary, ASCII, etc.) may ultimately be used to configure the device, but the data in the file is the same.
Table 15-10 shows the format of a non-encrypted bitstream. The bitstream consists of a comment field, a header,
the preamble, and the configuration setup and data.15-32
LatticeECP3 sysCONFIG Usage Guide
Table 15-10. Non-Encrypted Configuration Data
Table 15-11 shows a bitstream that is built for encryption but has not yet been encrypted. The highlighted areas will
be encrypted. The changes between Table 15-10 and Table 15-11 include the following:
• The Program Security frame (readback disable) has been moved to the beginning of the file so that readback is
turned off at the very beginning of configuration. This is an important security feature that prevents someone
from interrupting the configuration before completion and reading back unsecured data.
• A copy of the usercode is placed in the non-encrypted comment string. This has been done to allow you a
method to identify an encrypted file. For example, the usercode could be used as a file index. Note that the usercode itself, while encrypted in the configuration data file, is not encrypted on the device. At configuration the
usercode is decrypted and placed in the JTAG Usercode register. This allows you a method to identify the data in
the device. The JTAG Usercode register can be read back at any time, even when all SRAM readback paths
have been turned off. The usercode can be set to any 32-bit value. For information on how to set usercode, see
the ispLEVER or Diamond help facility.
• A copy of CONFIG_MODE, one of the global preferences, is placed in the non-encrypted comment string.
CONFIG_MODE can be SPI/SPIm, SSPI, Slave SCM, Slave PCM, Master PCM, or JTAG.

Table 15-11. Configuration File Just Before Encryption
Once encrypted, besides the obvious encryption of the data itself, the file will have additional differences from a
non-encrypted file (refer to Tables 15-12, 15-13, and 15-14).
• There are three preambles, the encryption preamble, alignment preamble, and the bitstream preamble. The
alignment preamble marks the beginning of the encrypted data. The entire original bitstream, including the bitstream preamble are all encrypted, per Table 15-11. The comment string, the encryption preamble, dummy data,
and alignment preamble are not encrypted.
• The decryption engine within the FPGA takes some time to perform its task; extra time is provided in one of two
ways. For master configuration modes (SPI and SPIm) the FPGA drives the configuration clock, so when extra
time is needed the FPGA stops sending configuration clocks. For slave configuration modes (Bitstream-Burst,
Slave Serial, and Slave Parallel) the data must be padded to create the extra time. Because of this there are several different file formats for encrypted data (see Tables 15-12, 15-13, and 15-14). Note that because of the time
needed to decrypt the bitstream it takes longer to configure from an encrypted data file than it does from a nonencrypted file. The bitstream sizes may vary depending on the configuration mode.

LatticeECP3 sysCONFIG Usage Guide
Table 15-14. Encrypted File Format for a Slave Parallel Mode
Decryption Flow
Compared to the encryption flow just discussed, the decryption flow is much simpler.
When data comes into the FPGA the decoder starts looking for the preamble and all information before the preamble is ignored. The preamble determines the path of the configuration data.
If the decoder detects a standard bitstream preamble in the bitstream it knows that this is a non-encrypted data file.
The decoder then selects the Raw data path.
If the decoder detects an encryption preamble in the bitstream it knows that this is an encrypted data file. If an
encryption key has not been programmed, the encrypted data is blocked and configuration fails (the DONE pin
stays low), if the proper key has been programmed then configuration can continue. The next block read contains
30,000 clocks of filler data. This delay allows time for the FPGA to read the key cells and prepare the decryption
engine. The decoder keeps reading the filler data looking for the alignment preamble. Once found, it knows that the
following data needs to go through the decryption engine. It first looks for the standard preamble. Once found, then
the SRAM cells’ programming begins.
But what happens if the key in the FPGA does not match the key used to encrypt the file? Once the data is
decrypted, the FPGA expects to find a valid standard bitstream preamble (BDB3), along with proper commands
and data that pass CRC checks. If the keys do not match then the decryption engine will not produce a proper configuration bitstream; either configuration will not start because the preamble was not found (the INITN pin stays
high and the DONE pin stays low) or CRC errors will occur, causing the INITN pin to go low to indicate the error.

Combining Configuration Modes
Multiple FPGAs, One SPI Flash
With a sufficiently large SPI Flash, multiple FPGAs can be configured as shown in Figure 15-17. The first FPGA is
configured in SPI mode; the following FPGAs are configured in Slave Serial mode.
Figure 15-17. Multiple FPGAs, One SPI Serial Flash
Figure 15-18. Slave SPI Example 1
The system diagram shown in Figure 15-18 illustrates one application of the Slave SPI interface, where the FPGA
selects the SPI Flash as the primary boot source. The modern CPU has the capability to program the SPI Flash
boot PROM as well as to command the FPGA to re-boot from the SPI Flash by toggling the PROGRAMN pin. This
requirement can only be met if the CPU drives the CCLK, and the MCLK is driven is by the FPGA for the SPI Flash
boot PROM as shown in Figure 15-18.
CS1N/HOLDN: When Slave SPI mode is used, this pin is an asynchronous active Low Input that tri-states the
serial read out data of the SPI port and sets the device to the suspend state by ignoring the clock. Set the SSPI
PERSISTENT to on to retain the pin as HOLDN pin to access the Slave SPI port in user mode.

Figure 15-19. Slave Parallel with Flowthrough
Chain Mode Options
The LatticeECP3 can be one of many FPGAs in a chain that each need to get configuration data. The Bypass and
Flowthrough options control how each FPGA in the chain of devices pass configuration bits to the other devices in
the chain. Successful configuration of a chain of FPGAs depends on a thorough understanding of the Bypass and
Flowthrough features.
Bypass Option
This option is used when you are configuring a chain of FPGAs in either parallel or serial daisy chain configurations. The Bypass option, when enabled, adds an additional command to the end of the configuration bitstream
being sent to the LatticeECP3. The LatticeECP3 receives all of the configuration bits, and upon reception of the
BYPASS command it enables a serial bypass register. This bypass register passes all incoming configuration bits
to the DOUT pin for use by the next FPGA in the chain. Prior to the LatticeECP3 receiving the BYPASS command
the internal bypass register is initialized to ‘1’. Any FPGA receiving data from the DOUT pin will see a long string of
ones until the BYPASS command is accepted by the LatticeECP3.
The following conditions must be met when Bypass is enabled:
• The PERSISTENT option must be set to Slave Parallel mode
• The bitstream can not be encrypted
• The LatticeECP3 can not be in SPIm mode
The Bypass Option is DISABLED by default.
Flowthrough Option
The Flowthrough option is used when you are configuring a chain of FPGAs in Slave Parallel Configuration mode.
It is not applicable to any other configuration mode. The Flowthrough option, when enabled, adds a
FLOWTHROUGH command to the end of the bitstream for the LatticeECP3. The LatticeECP3 receives all of the
configuration data over the Slave Parallel data bus. When it receives the FLOWTHROUGH command it asserts the
CSON output pin driving the parallel bus chip select input of the next FPGA in the chain. Until reception of the

Reset Configuration RAM in Reconfiguration (T/F)
When this switch is set to true, it directs the bitstream to reinitialize the device when configuration starts. When the
switch is set to false, it directs the bitstream to program the device to retain the current configuration and allows for
additional bitstream configuration. The default is true. Use of the feature requires you to be aware of potential contention issues with the prior configuration loaded into the FPGA.

Appendix B. Lattice Diamond Usage Overview
This appendix discusses the use of Lattice Diamond design software for projects that include the LatticeECP2M
SERDES/PCS module .
For general information about the use of Lattice Diamond, refer to the Lattice Diamond Tutorial.
If you have been using ispLEVER software for your FPGA design projects, Lattice Diamond may look like a big
change. But if you look closer, you will find many similarities because Lattice Diamond is based on the same toolset
and work flow as ispLEVER. The changes are intended to provide a simpler, more integrated, and more enhanced
user interface.
Converting an ispLEVER Project to Lattice Diamond
Design projects created in ispLEVER can easily be imported into Lattice Diamond. The process is automatic
except for the ispLEVER process properties, which are similar to the Diamond strategy settings, and PCS modules.
After importing a project, you need to set up a strategy for it and regenerate any PCS modules.
Importing an ispLEVER Design Project
Make a backup copy of the ispLEVER project or make a new copy that will become the Diamond project.
1. In Diamond, choose File > Open > Import ispLEVER Project.
2. In the ispLEVER Project dialog box, browse to the project’s .syn file and open it.
3. If desired, change the base file name or location for the Diamond project. If you change the location, the
new Diamond files will go into the new location, but the original source files will not move or be copied. The
Diamond project will reference the source files in the original location.
The project files are converted to Diamond format with the default strategy settings.
Adjusting PCS Modules
PCS modules created with IPexpress have an unusual file structure and need additional adjustment when importing a project from ispLEVER. There are two ways to do this adjustment. The preferred method is to regenerate the
module in Diamond. However this may upgrade the module to a more recent version. An upgrade is usually desirable but if, for some reason, you do not want to upgrade the PCS module, you can manually adjust the module by
copying its .txt file into the implementation folder. If you use this method, you must remember to copy the .txt file
into any future implementation folders.
Regenerate PCS Modules
1. Find the PCS module in the Input Files folder of File List view. The module may be represented by an .lpc,
.v, or .vhd file.
2. If the File List view shows the Verilog or VHDL file for the module, and you want to regenerate the module,
import the module’s .lpc file:
a. In the File List view, right-click the implementation folder ( ) and choose Add > Existing File.
b. Browse for the module’s .lpc file, .lpc, and select it.
c. Click Add. The .lpc file is added to the File List view.
d. Right-click the module’s Verilog or VHDL file and choose Remove.
3. In File List, double-click the module’s .lpc file. The module’s IPexpress dialog box opens.
4. In the bottom of the dialog box, click Generate. The Generate Log tab is displayed. Check for errors and
close.15-42
LatticeECP3 sysCONFIG Usage Guide
In File List, the .lpc file is replaced with an .ipx file. The IPexpress manifest (.ipx) file is new with Diamond. The .ipx
file keeps track of the files needed for complex modules.
Using IPexpress with Lattice Diamond
Using IPexpress with Lattice Diamond is essentially same as with ispLEVER.
The configuration GUI tabs are all the same except for the Generation Options tab. Figure 15-20 shows the Generation Options tab window.
Figure 15-20. Generation Options Tab
Table 15-17. SERDES_PCS GUI Attributes – Generation Options Tab
GUI Text Description
Automatic Automatically generates the HDL and configuration(.txt) files as needed. Some
changes do not require regenerating both files.
Force Module and Settings Generation Generates both the HDL and configuration files.
Force Settings Generation Only Generates only the attributes file. You get an error message if the HDL file also
needs to be generated.
Force Place & Route Process Reset Resets the Place & Route Design process, forcing it to be run again with the
newly generated PCS module.
Force Place & Route Trace Process Reset Resets the Place & Route Trace process, forcing it to be run again with the newly
generated PCS module.
Note:
Automatic is set as the default option. If either Automatic or Force Settings Generation Only and no sub-options (Process Reset Options) are
checked and the HDL module is not generated, the reset pointer is set to Bitstream generation automatically.
After the Generation is finished, the reset marks in the process window will be reset accordingly.15-43

Creating a New Simulation Project Using Simulation Wizard
This section describes how to use the Simulation Wizard to create a simulation project (.spf) file so you can import
it into a standalone simulator.
1. In Project Navigator, click Tools > Simulation Wizard. The Simulation Wizard opens.
2. In the Preparing the Simulator Interface page click Next.
3. In the Simulator Project Name page, enter the name of your project in the Project Name text box and
browse to the file path location where you want to put your simulation project using the Project Location
text box and Browse button.
When you designate a project name in this wizard page, a corresponding folder will be created in the file
path you choose. Click Yes in the popup dialog that asks you if you wish to create a new folder.
4. Click either the Active-HDL®
or ModelSim®
simulator check box and click Next.
5. In the Process Stage page choose which type of Process Stage of simulation project you wish to create
Valid types are RTL, Post-Synthesis Gate-Level, Post-Map Gate-Level, and Post-Route Gate-level+Timing.
Only those process stages that are available are activated.
Note that you can make a new selection for the current strategy if you have more than one defined in your
project.
The software supports multiple strategies per project implementation which allow you to experiment with
alternative optimization options across a common set of source files. Since each strategy may have been
processed to different stages, this dialog allows you to specify which stage you wish to load.
6. In the Add Source page, select from the source files listed in the Source Files list box or use the browse
button on the right to choose another desired source file. Note that if you wish to keep the source files in
the local simulation project directory you just created, check the Copy Source to Simulation Directory
option.
7. Click Next and a Summary page appears and provides information on the project selections including the
simulation libraries. By default, the Run Simulator check box is enabled and will launch the simulation tool
you chose earlier in the wizard in the Simulator Project Name page.
8. Click Finish.
The Simulation Wizard Project (.spf) file and a simulation script DO file are generated after running the wizard. You
can import the DO file into your current project if desired. If you are using Active-HDL, the wizard will generate an
.ado file and if you are using ModelSim, it creates and .mdo file.
Note: PCS configuration file, (.txt) must be added in step 6.

MachXO2™ Devices Usage Guide which explains the software usage. In this document you will find:
• WISHBONE Protocol
• EFB Register Map
• Command Sequences
• Examples
As an overview, the MachXO2 FPGA family combines a high-performance, low power, FPGA fabric with built-in,
hardened control functions and on-chip User Flash Memory (UFM). The hardened control functions ease design
implementation and save general purpose resources such as LUTs, registers, clocks and routing. The hardened
control functions are physically located in the Embedded Function Block (EFB). All MachXO2 devices include an
EFB module. The EFB block includes the following control functions:
• Two I2
C Cores
• One SPI Core
• One 16-bit Timer/Counter
• Interface to Flash Memory which includes:
– User Flash Memory for MachXO2-640 and higher densities
– Configuration Logic
• Interface to Dynamic PLL configuration settings
• Interface to On-chip Power Controller through I2
C and SPI
Figure 17-1 shows the EFB architecture and the interface to the FPGA core logic.

EFB Register Map
The EFB module has a Register Map to allow the service of the hardened functions through the WISHBONE bus
interface read/write operations. Each hardened function has dedicated 8-bit Data and Control registers, with the
exception of the Flash Memory (UFM/Configuration), which are accessed through the same set of registers.
Table 17-1 documents the register map of the EFB module. The PLL registers are located in the MachXO2 PLL
modules, but they are accessed through EFB WISHBONE read/write cycles.

Address spaces that are not defined in Table 17-1 are invalid and will result in non-deterministic results. It is the
responsibility of the designer to ensure valid addresses are presented to the EFB WISHBONE slave interface.

WISBONE Bus Interface
The WISHBONE Bus in the MachXO2 is compliant with the WISHBONE standard from OpenCores. It provides
connectivity between FPGA user logic and the EFB functional blocks. The user can implement a WISHBONE Master interface to interact with the EFB WISHBONE slave interface or a LatticeMico8™ soft processor core can be
used to interact with the EFB WISHBONE.
The block diagram in Figure 17-2 shows the supported WISHBONE bus signals between the FPGA core and the
EFB. Table 17-2 provides a detailed definition of the supported signals.
Figure 17-2. WISHBONE Bus Interface Between the FPGA Core and the EFB Module
Table 17-2. WISHBONE Slave Interface Signals of the EFB Module
Signal Name I/O Width Description
wb_clk_i Input 1 Positive edge clock used by WISHBONE Interface registers and hardened functions
within the EFB module. Supports clock speeds up to 133 MHz.
wb_rst_i Input 1
Active-high, synchronous reset signal that will only reset the WISHBONE interface
logic. This signal will not affect the contents of any registers. It will only affect ongoing
bus transactions. Wait 1us after de-assertion before starting any subsequent WISHBONE transactions.
wb_cyc_i Input 1 Active-high signal, asserted by the WISHBONE master, indicates a valid bus cycle is
present on the bus.
wb_stb_i Input 1
Active-high strobe, input signal, indicating the WISHBONE slave is the target for the
current transaction on the bus. The EFB module asserts an acknowledgment in
response to the assertion of the strobe.
wb_we_i Input 1 Level sensitive Write/Read control signal. Low indicates a Read operation, and High
indicates a Write operation.
wb_adr_i Input 8 8-bit wide address used to select a specific register from the register map of the EFB
module.
wb_dat_i Input 8 8-bit input data path used to write a byte of data to a specific register in the register
map of the EFB module.
wb_dat_o Output 8 8-bit output data path used to read a byte of data from a specific register in the register map of the EFB module.
wb_ack_o Output 1 Active-high, transfer acknowledge signal asserted by the EFB module, indicating the
requested transfer is acknowledged.

User Logic17-4
Using User Flash Memory and Hardened
Control Functions in MachXO2 Devices Reference Guide
To interface to the EFB you must create a WISHBONE Master controller in the User Logic. In a multiple-Master
configuration, the WISHBONE Master outputs are multiplexed in a user-defined arbiter. A LatticeMico8 soft processor can also be utilized along with the Mico System Builder (MSB) platform which can implement multi-Master bus
configurations. If two Masters request the bus in the same cycle, only the outputs of the arbitration winner reach the
Slave interface.
The EFB WISHBONE bus supports the “Classic” version of the WISHBONE standard. Given that the WISHBONE
bus is an open source standard, not all features of the standard are implemented or required:
• Tags are not supported in the WISHBONE Slave interface of the EFB module. Given that the EFB is a hardened
block, these signals cannot be added by the user.
• The Slave WISHBONE bus interface of the EFB module does not require the byte select signals (sel_i or sel_o),
since the data bus is only a single byte wide.
• The EFB WISHBONE slave interface does not support the optional error and retry access termination signals. If
the slave receives an access to an invalid address, it will simply respond by asserting wb_ack_o signal. It is the
responsibility of the user to stay within the valid address range.
WISHBONE Write Cycle
Figure 17-3 shows the waveform of a Write cycle from the perspective of the EFB WISHBONE Slave interface. During a single Write cycle, only one byte of data is written to the EFB block from the WISHBONE Master. A Write
operation requires a minimum three clock cycles.
On clock Edge 0, the Master updates the address, data and asserts control signals. During this cycle:
• The Master updates the address on the wb_adr_i[7:0] address lines
• Updates the data that will be written to the EFB block, wb_dat_i[7:0] data lines
• Asserts the write enable wb_we_i signal, indicating a write cycle
• Asserts the wb_cyc_i to indicate the start of the cycle
• Asserts the wb_stb_i, selecting a specific slave module
On clock Edge 1, the EFB WISHBONE Slave decodes the input signals presented by the master. During this cycle:
• The Slave decodes the address presented on the wb_adr_i[7:0] address lines
• The Slave prepares to latch the data presented on the wb_dat_i[7:0] data lines
• The Master waits for an active-high level on the wb_ack_o line and prepares to terminate the cycle on the next
clock edge, if an active-high level is detected on the wb_ack_o line
• The EFB may insert wait states before asserting wb_ack_o, thereby allowing it to throttle the cycle speed. Any
number of wait states may be added
• The Slave asserts wb_ack_o signal
The following occurs on clock Edge 2:
• The Slave latches the data presented on the wb_dat_i[7:0] data lines
• The Master de-asserts the strobe signal, wb_stb_i, the cycle signal, wb_cyc_i, and the write enable signal,
wb_we_i
• The Slave de-asserts the acknowledge signal, wb_ack_o, in response to the Master de-assertion of the strobe
signal17-5

Figure 17-3. WISHBONE Bus Write Operation
WISHBONE Read Cycle
Figure 17-4 shows the waveform of a Read cycle from the perspective of the EFB WISHBONE Slave interface.
During a single Read cycle, only one byte of data is read from the EFB block by the WISHBONE master. A Read
operation requires a minimum three clock cycles.
On clock Edge 0, the Master updates the address, data and asserts control signals. The following occurs during
this cycle:
• The Master updates the address on the wb_adr_i[7:0] address lines
• De-asserts the write enable wb_we_i signal, indicating a Read cycle
• Asserts the wb_cyc_i to indicate the start of the cycle
• Asserts the wb_stb_i, selecting a specific Slave module
On clock Edge 1, the EFB WISHBONE slave decodes the input signals presented by the master. The following
occurs during this cycle:
• The Slave decodes the address presented on the wb_adr_i[7:0] address lines
• The Master prepares to latch the data presented on wb_dat_o[7:0] data lines from the EFB WISHBONE slave on
the following clock edge
• The Master waits for an active-high level on the wb_ack_o line and prepares to terminate the cycle on the next
clock edge, if an active-high level is detected on the wb_ack_o line
• The EFB may insert wait states before asserting wb_ack_o, thereby allowing it to throttle the cycle speed. Any
number of wait states may be added.
• The Slave presents valid data on the wb_dat_o[7:0] data lines
• The Slave asserts wb_ack_o signal in response to the strobe, wb_stb_i signal

C is a widely used two-wire serial bus for communication between devices on the same board. Every MachXO2
device contains two hardened I2
C IP cores designated as the “Primary” and “Secondary” I2
C IP cores. Either of the
two cores can be operated as an I2
C Master or as an I2
C Slave. The difference between the two cores is that the
Primary core has pre-assigned I/O pins while the ports of the secondary core can be assigned by designers to any
general purpose I/O. In addition, the Primary I2

CKSDIS Clock Stretching Disable. The I2
C cores support a “wait state” or clock stretching from
the slave, meaning the slave can enforce a wait state if it needs time to finish the task.
Bit CKSDIS disables the clock stretching if desired by the user. In this case, the overflow flag must be monitored. For Master operations, set this bit to ‘0’. Clock stretching
will be used by the MachXO2 EFB I2
C Slave during both ‘read’ and ‘write’ operations
(from the Master perspective) when I2
C Command Register bit CKSDIS=0.
During a read operation (Slave transmitting), clock stretching occurs when TXDR is
empty (under-run condition). During a write operation (Slave receiving) clock stretching occurs when RXDR is full (over-run condition).
Translated into I2
C Status register bits, the I2
C clock-stretches if TRRDY=1. The decision to enable clock stretching is done on the 8TH SCL + 2 WISHBONE clocks.

C Clock Prescale 0 (Primary/Secondary)
Table 17-7. I2
C Register Clock Prescale 1 (Primary/Secondary)
I2C_PRESCALE[9:0] I2
C Clock Prescale value. A write operation to I2CBR [9:8] will cause an I2
C core reset.
The WISHBONE clock frequency is divided by (I2C_PRESCALE*4) to produce the
Master I2
C clock frequency supported by the I2
C bus (50KHz, 100KHz, 400KHz).
Note: Different from transmitting a Master, the practical limit for Slave I2
C bus speed support is (WISHBONE
clock)/2048. For example, the maximum WISHBONE clock frequency to support a 50 KHz Slave I2
C operation is
102 MHz.
Note: The digital value is calculated by IPexpress™ when the I2
C core is configured in the I2
C tab of the EFB GUI.
The calculation is based on the WISHBONE Clock Frequency and the I2
C Frequency, both entered by the user. The
digital value of the divider is programmed in the MachXO2 device during device programming. After power-up or
device reconfiguration, the data is loaded onto the I2C_1_BR1/0 and I2C_2_BR1/0 registers.
Registers I2C_1_BR1/0 and I2C_2_BR1/0 have Read/Write access from the WISHBONE interface. Designers can
update these clock pre-scale registers dynamically during device operation; however, care must be taken to not violate the I2
C bus frequencies.

Hardened SPI IP Core
The MachXO2 EFB contains a hard SPI IP core that can be configured as a SPI Master or Slave. When the SPI
core is configured as a Master it is able to control other devices with Slave SPI interfaces that are connected to the
SPI bus. When the SPI core is configured as a Slave, it is able to interface to an external SPI Master device.
SPI Registers
The SPI core communicates with the WISHBONE interface through a set of control, command, status and data
registers. Table 17-16 shows the register names and their functions. These registers are a subset of the EFB register map.

MSTR SPI Master/Slave Mode. Selects the Master/Slave operation mode of the SPI core.
Changing this bit forces the SPI system into idle state.
0: SPI is in Slave mode
1: SPI is in Master mode
MCSH SPI Master CSSPIN Hold. Holds the Master chip select active when the host is busy,
to halt the data transmission without de-asserting chip select.
Note: This mode must be used only when the WISHBONE clock has been divided by
a value greater than four (4) (greater than six (6) for R1 devices). For more details on
the R1 to Standard migration refer to AN8086, Designing for Migration from
MachXO2-1200-R1 to Standard (Non-R1) Devices.
0: Master running as normal
1: Master holds chip select low even if there is no data to be transmitted
SDBRE Slave Dummy Byte Response Enable. Enables Lattice proprietary extension to the
SPI protocol. For use when the internal support circuit (e.g. WISHBONE host) cannot
respond with initial data within the time required, and to make the slave read out data
predictably available at high SPI clock rates.
When enabled, dummy 0xFF bytes will be transmitted in response to a SPI slave read
(while SPISR[TRDY]=1) until an initial write to SPITXDR. Once a byte is written into
SPITXDR by the WISHBONE host, a single byte of 0x00 will be transmitted then followed immediately by the data in SPITXDR. In this mode, the external SPI master
should scan for the initial 0x00 byte when reading the SPI slave to indicate the beginning of actual data. Refer to Figure 17-19.
0: Normal Slave SPI operation
1: Lattice proprietary Slave Dummy Byte Response Enabled
Note: This mechanism only applies for the initial data delay period. Once the initial
data is available, subsequent data must be supplied to SPITXDR at the required SPI
bus data rate.
CPOL SPI Clock Polarity. Selects an inverted or non-inverted SPI clock. To transmit data
between SPI modules, the SPI modules must have identical SPICR2[CPOL] values. In
master mode, a change of this bit will abort a transmission in progress and force the
SPI system into idle state. Refer to Figures 17-25 through 17-28.
0: Active-high clocks selected. In idle state SCK is low.
1: Active-low clocks selected. In idle state SCK is high.
CPHA SPI Clock Phase. Selects the SPI clock format. In master mode, a change of this bit
will abort a transmission in progress and force the SPI system into idle state. Refer to
Refer to Figures 17-25 through 17-28.
0: Data is captured on a leading (first) clock edge, and propagated on the
opposite clock edge.
1: Data is captured on a trailing (second) clock edge, and propagated on the
opposite clock edge*.
Note: When CPHA=1, the user must explicitly place a pull-up or pull-down on SCK
pad corresponding to the value of CPOL (e.g. when CPHA=1 and CPOL=0 place a
pull-down on SCK). When CPHA=0, the pull direction may be set arbitrarily.
Slave SPI Configuration mode supports default setting only for CPOL, CPHA.
LSBF LSB-First. LSB appears first on the SPI interface. In master mode, a change of this bit
will abort a transmission in progress and force the SPI system into idle state. Refer to 17-24
Using User Flash Memory and Hardened
Control Functions in MachXO2 Devices Reference Guide
Figures 17-25 through 17-28.
Note: This bit does not affect the position of the MSB and LSB in the data register.
Reads and writes of the data register always have the MSB in bit 7.
0: Data is transferred most significant bit (MSB) first
1: Data is transferred least significant bit (LSB) first
Table 17-20. SPI Clock Prescale
DIVIDER[5:0] SPI Clock Prescale value. The WISHBONE clock frequency is divided by
(DIVIDER[5:0] + 1) to produce the desired SPI clock frequency. A write operation to
this register will cause a SPI core reset. DIVIDER must be >= 1.
Note: The digital value is calculated by IPexpress when the SPI core is configured in
the SPI tab of the EFB GUI. The calculation is based on the WISHBONE Clock Frequency and the SPI Frequency, both entered by the user. The digital value of the
divider is programmed in the MachXO2 device during device programming. After
power-up or device reconfiguration, the data is loaded onto the SPIBR register.
Register SPIBR has Read/Write access from the WISHBONE interface. Designers
can update the clock pre-scale register dynamically during device operation.
Table 17-21. SPI Master Chip Select
CSN_[7:0] SPI Master Chip Selects. Used in master mode for asserting a specific Master Chip
Select (MCSN) line. The register has eight bits, enabling the SPI core to control up to
eight external SPI slave devices Each bit represents one master chip select line
(Active-Low). Bits [7:1] may be connected to any I/O pin via the FPGA fabric. Bit 0 has
a pre-assigned pin location. The register has Read/Write access from the WISHBONE
interface. A write operation on this register will cause the SPI core to reset.

SPI_Transmit_Data[7:0] SPI Transmit Data. This register holds the byte that will be transmitted on the SPI bus.
Bit 0 in this register is LSB, and will be transmitted last when SPICR2[LSBF]=0 or first
when SPICR2[LSBF]=1.
Note: When operating as a Slave, SPITXDR must be written when SPISR[TRDY] is '1'
and at least 0.5 CCLKs before the first bit is to appear on SO. For example, when
CPOL = CPHA = TXEDGE = LSBF = 0, SPITXDR must be written prior to the CCLK
rising edge used to sample the LSB (bit 0) of the previous byte. See Figure 17-25.
This timing requires at least one protocol dummy byte be included for all slave SPI
read operations.

Hardened Timer/Counter PWM
The MachXO2 EFB contains a hard Timer/Counter IP core. This Timer/Counter is a general purpose, bi-directional,
16-bit Timer/Counter module with independent output compare units and PWM support.
Timer/Counter Registers
The Timer/Counter communicates with the FPGA logic through the WISHBONE interface, by utilizing a set of control, status and data registers. Table 17-29 shows the register names and their functions. These registers are a
subset of the EFB register map. Refer to the EFB register map for specific addresses of each register.

Table 17-43. Timer/Counter Current Capture Counter Value 0
Table 17-44. Timer/Counter Current Capture Counter Value 1
Registers TCICR0 and TCICR1 are 8-bit registers, which combined, can hold the counter value. The counter value
is loaded onto these registers once a trigger event, tc_ic IP signal, is asserted. The capture value is commonly
used as a time-stamp for a specific system event. The WISHBONE host has read-only access to these registers.
TCICR0 register holds the lower 8-bit value [7:0] of the counter value. TCICR1 register holds the upper 8-bit value
[15:8] of the counter value.

Flash Memory (UFM/Configuration) Access Ports
Designers can access the UFM Sector via JTAG port (compliant with the IEEE 1149.1 and IEEE 1532 specifications), external Slave SPI port and external I2
C Primary port and the internal WISHBONE interface of the EFB
module. Figure 17-25 illustrates the interfaces to the UFM and Configuration Memory sectors.
Figure 17-25. Interfaces to the UFM/Configuration Sectors
The configuration logic arbitrates access from the interfaces by the following priority. When higher priority ports are
enabled Flash Memory access by lower priority ports will be blocked.
1. JTAG Port
2. Slave SPI Port
3. I2
C Primary Port
4. WISHBONE Slave Interface
Note: Enabling Flash Memory (UFM/Configuration) Interface using Enable Configuration Interface command 0x74
Transparent Mode will temporarily disable certain features of the device including:
• Power Controller
• GSR
• Hardened User SPI port

Flash Memory (UFM/Configuration) Access through WISHBONE Slave Interface
The WISHBONE Slave interface of the EFB module enables designers to access the Flash Memory (UFM/Configuration) directly from the FPGA core logic. The WISHBONE bus signals, described earlier in this document, are utilized by a WISHBONE host that designers can implement using the general purpose FPGA resources. In addition
to the WISHBONE bus signals, an interrupt request output signal is brought to the FPGA fabric. The IP signal is
“wbc_ufm_irq”, and it functions as an interrupt request to the internal WISHBONE host, based on the data
Read/Write FIFO status or arbitration error.
Note: To access the Flash Memory (UFM/Configuration) via WISHBONE in R1 devices, the hard SPI port or the
primary I2
C port must be enabled. For more details, refer to AN8086, Designing for Migration from MachXO2-1200-
R1 to Standard (Non-R1) Devices.
The WISHBONE Interface communicates to the Configuration Logic through a set of data, control and status registers. Table 17-49 shows the register names and their functions. These registers are a subset of the EFB register
map. Refer to the EFB register map for specific addresses of each register.

WBCE WISHBONE Connection Enable. Enables the WISHBONE to establish the read/write
connection to the Flash Memory (UFM/Configuration) logic. This bit must be set prior

information on framing WISHBONE commands.

WISHBONE Framing
To access the Flash Memory (UFM/Configuration) each command string sent to the WISHBONE EFB ports must
be correctly ‘framed’ using the protocol defined for each interface. In the case of the internal WISHBONE port,
each command string is preceded by setting CFGCR[WBCE]. Similarly, each command string is followed by clearing the CFGCR[WBCE] bit.

Command and Data Transfers to Flash Memory (UFM/Configuration) Space
The command and data transfers to the Flash Memory (UFM/Configuration) are identical for all the access ports,
regardless of their different physical interfaces. The Flash Memory (UFM/Configuration) is organized in pages.
Therefore, users address a specific page for Read or Write operations to that page. Each page has 128 bits (16
bytes). The transfers are based on a set of instructions and page addresses. The Flash memory is composed of

Table 17-72. Refresh (0x79)
Example: 0x79 00 00
Issue Refresh command
Note: The Refresh command will Launch Boot sequence
Must have only two operands
After completing the Refresh command (e.g. SPI SN deassertion or I2
C stop), further
bus accesses are prohibited for the duration of tREFRESH. Violating this requirement
will cause the Refresh process to abort and leave the MachXO2 device in an unprogrammed state.
Occasionally, following a device REFRESH or PROGRAMN pin toggle, the secondary
I
2
C port may be left in an undefined (non-idle) state. The likely hood of this condition is
design and route dependent. To positively return the Secondary I2
C port to the idle
state, write a value of 0x40 to register I2C_2_CMDR via WISHBONE immediately
after device reset is released. This will cause a short low-pulse on SCK as the hardblock signals a STOP on the bus then returns to the idle state. Failure to manually
return the Secondary I2
C port to the idle state may result in an I2
C bus lock-up condition. Normal I2
C activity can be commenced without additional delay

Interface to Configuration Flash
The WISHBONE interface of the EFB module allows a WISHBONE host to access the configuration resources of
the MachXO2 devices. This can be particularly useful for reading data from configuration resources such as
USERCODE and TraceID. Most importantly, this feature allows users to update the Configuration Flash array of the
devices while the device is in operation mode. This is a self-configuration operation. Upon power-up or a configuration refresh operation, the new content of the Configuration Flash is loaded into the Configuration SRAM and the
device continues operation with a new configuration.
The data transfer and execution of operations is the same as the one documented in the UFM section of this document. This is due to the fact that the UFM is also a Flash Memory resource and the communication between the
WISHBONE host and the configuration logic is performed through the same command, status and data registers.
Please see Tables 17-49 to 17-57 for information on these registers.
Figure 17-28 shows a basic flow diagram for implementing a Configuration Flash Update initiated via any of the
sysCONFIG ports (I2
C, SPI, or WISHBONE).
For detailed information on MachXO2 programming and configuration, see TN1204, MachXO2 Programming and
Configuration Usage Guide.

Flash Memory Erase and Program Performance
Table 17-93. Flash Memory (UFM/Configuration) Performance in MachXO2 Devices1
Erase/Program/Verify Time Calculation Example
Using the data above, it is possible to roughly calculate the time required to perform an Erase/Program/Verify operation. The calculation assumes nearly 100% bus utilization. Overhead required by bus master processes, if any, is
not accounted for in the equation below.
E/P/V time (us): tEPV = tE + tP + tV
where: tE = tECFG + tEUFM1
tP = 0.2us * number of Pages to program2
tV = (8 * number of Pages programmed) * BusEff * tBUSCLK
UFM Write and Read Examples
The UFM and Configuration sectors support page-oriented read and write operations while erase operations are
sector-based. Consistent with many Flash memory devices, byte-oriented operations are not supported. Also, as
typical with Flash memory devices, attempting to modify a previously written location in Flash requires a read-modify-write operation on the smallest erasable Flash unit. In the case of MachXO2, the smallest erasable unit is the
entire UFM sector or the entire Configuration Sector.
For example, to arbitrarily modify a byte value in the UFM, the user must:
1. Read and save all UFM data to an alternate location (e.g. EBR);
2. Erase the UFM sector;
3. Modify the selected byte; and
4. Program the UFM page by page.

1. Sector erase times are additive. If a sector (e.g. CFG) is not erased, its erase time is 0.
2. Data transfer time is insignificant to tP for high-speed data protocols. To account for slow bus speeds (E.g. I2
C) multiply tV by 2.
3. Bus efficiency approaches this value as number of read pages increases. 17-67

Lattice Ordering Guidelines for Standard Product
Lattice requests, at a minimum, that devices be purchased at the tube/tray quantity level and
recommend full box quantities as the optimal quantity level when volumes warrant it. Shipping in
full tube, tray and box quantities contributes significantly to the quality and accuracy of our
shipments buy eliminating the handling associated with partial box, tube or tray shipments. This
reduced handling minimizes device damage, moisture exposure and count errors.

and oscillators dynamically. These features help manage static and dynamic power consumption resulting in low
static power for all members of the family.
The MachXO2 devices are available in two versions – ultra low power (ZE) and high performance (HC and HE)
devices. The ultra low power devices are offered in three speed grades -1, -2 and -3, with -3 being the fastest. Similarly, the high-performance devices are offered in three speed grades: -4, -5 and -6, with -6 being the fastest. HC
devices have an internal linear voltage regulator which supports external VCC supply voltages of 3.3V or 2.5V. ZE
and HE devices only accept 1.2V as the external VCC supply voltage. With the exception of power supply voltage
all three types of devices (ZE, HC and HE) are functionally compatible and pin compatible with each other.
The MachXO2 PLDs are available in a broad range of advanced halogen-free packages ranging from the space
saving 2.5x2.5 mm WLCSP to the 23x23 mm fpBGA. MachXO2 devices support density migration within the same
package. Table 1-1 shows the LUT densities, package and I/O options, along with other key parameters.
The pre-engineered source synchronous logic implemented in the MachXO2 device family supports a broad range
of interface standards, including LPDDR, DDR, DDR2 and 7:1 gearing for display I/Os.
The MachXO2 devices offer enhanced I/O features such as drive strength control, slew rate control, PCI compatibility, bus-keeper latches, pull-up resistors, pull-down resistors, open drain outputs and hot socketing. Pull-up, pulldown and bus-keeper features are controllable on a “per-pin” basis.
A user-programmable internal oscillator is included in MachXO2 devices. The clock output from this oscillator may
be divided by the timer/counter for use as clock input in functions such as LED control, key-board scanner and similar state machines.
The MachXO2 devices also provide flexible, reliable and secure configuration from on-chip Flash memory. These
devices can also configure themselves from external SPI Flash or be configured by an external master through the
JTAG test access port or through the I2
C port. Additionally, MachXO2 devices support dual-boot capability (using
external Flash memory) and remote field upgrade (TransFR) capability.
Lattice provides a variety of design tools that allow complex designs to be efficiently implemented using the
MachXO2 family of devices. Popular logic synthesis tools provide synthesis library support for MachXO2. Lattice
design tools use the synthesis tool output along with the user-specified preferences and constraints to place and
route the design in the MachXO2 device. These tools extract the timing from the routing and back-annotate it into
the design for timing verification.
Lattice provides many pre-engineered IP (Intellectual Property) LatticeCORE™ modules, including a number of
reference designs licensed free of charge, optimized for the MachXO2 PLD family. By using these configurable soft
core IP cores as standardized blocks, users are free to concentrate on the unique aspects of their design, increasing their productivity.www.latticesemi.com 2-1 DS1035 Architecture_01.5

Architecture Overview
The MachXO2 family architecture contains an array of logic blocks surrounded by Programmable I/O (PIO). The
larger logic density devices in this family have sysCLOCK™ PLLs and blocks of sysMEM Embedded Block RAM
(EBRs). Figures 2-1 and 2-2 show the block diagrams of the various family members.

MachXO2 Family Data Sheet
Architecture2-2
Architecture
MachXO2 Family Data Sheet
The logic blocks, Programmable Functional Unit (PFU) and sysMEM EBR blocks, are arranged in a two-dimensional grid with rows and columns. Each row has either the logic blocks or the EBR blocks. The PIO cells are
located at the periphery of the device, arranged in banks. The PFU contains the building blocks for logic, arithmetic,
RAM, ROM, and register functions. The PIOs utilize a flexible I/O buffer referred to as a sysIO buffer that supports
operation with a variety of interface standards. The blocks are connected with many vertical and horizontal routing
channel resources. The place and route software tool automatically allocates these routing resources.
In the MachXO2 family, the number of sysIO banks varies by device. There are different types of I/O buffers on the
different banks. Refer to the details in later sections of this document. The sysMEM EBRs are large, dedicated fast
memory blocks; these blocks are found in MachXO2-640/U and larger devices. These blocks can be configured as
RAM, ROM or FIFO. FIFO support includes dedicated FIFO pointer and flag “hard” control logic to minimize LUT
usage.
The MachXO2 architecture also provides up to two sysCLOCK Phase Locked Loop (PLL) blocks on MachXO2-
640U, MachXO2-1200/U and larger devices. These blocks are located at the ends of the on-chip Flash block. The
PLLs have multiply, divide, and phase shifting capabilities that are used to manage the frequency and phase relationships of the clocks.
MachXO2 devices provide commonly used hardened functions such as SPI controller, I2
C controller and timer/
counter. MachXO2-640/U and higher density devices also provide User Flash Memory (UFM). These hardened
functions and the UFM interface to the core logic and routing through a WISHBONE interface. The UFM can also
be accessed through the SPI, I2
C and JTAG ports.
Every device in the family has a JTAG port that supports programming and configuration of the device as well as
access to the user logic. The MachXO2 devices are available for operation from 3.3V, 2.5V and 1.2V power supplies, providing easy integration into the overall system.
PFU Blocks
The core of the MachXO2 device consists of PFU blocks, which can be programmed to perform logic, arithmetic,
distributed RAM and distributed ROM functions. Each PFU block consists of four interconnected slices numbered 0
to 3 as shown in Figure 2-3. Each slice contains two LUTs and two registers. There are 53 inputs and 25 outputs
associated with each PFU block.

Slices
Slices 0-3 contain two LUT4s feeding two registers. Slices 0-2 can be configured as distributed memory. Table 2-1
shows the capability of the slices in PFU blocks along with the operation modes they enable. In addition, each PFU
contains logic that allows the LUTs to be combined to perform functions such as LUT5, LUT6, LUT7 and LUT8.
The control logic performs set/reset functions (programmable as synchronous/ asynchronous), clock select, chipselect and wider RAM/ROM functions.
Table 2-1. Resources and Modes Available per Slice
Figure 2-4 shows an overview of the internal logic of the slice. The registers in the slice can be configured for positive/negative and edge triggered or level sensitive clocks. All slices have 15 inputs from routing and one from the
carry-chain (from the adjacent slice or PFU). There are seven outputs: six for routing and one to carry-chain (to the
adjacent PFU). Table 2-2 lists the signals associated with Slices 0-3.

Table 2-2. Slice Signal Descriptions
Modes of Operation
Each slice has up to four potential modes of operation: Logic, Ripple, RAM and ROM.
Logic Mode
In this mode, the LUTs in each slice are configured as 4-input combinatorial lookup tables. A LUT4 can have 16
possible input combinations. Any four input logic functions can be generated by programming this lookup table.
Since there are two LUT4s per slice, a LUT5 can be constructed within one slice. Larger look-up tables such as
LUT6, LUT7 and LUT8 can be constructed by concatenating other slices. Note LUT8 requires more than four
slices.
Ripple Mode
Ripple mode supports the efficient implementation of small arithmetic functions. In Ripple mode, the following functions can be implemented by each slice:
• Addition 2-bit
• Subtraction 2-bit
• Add/subtract 2-bit using dynamic control
• Up counter 2-bit
• Down counter 2-bit
• Up/down counter with asynchronous clear
• Up/down counter with preload (sync)
• Ripple mode multiplier building block
• Multiplier support
• Comparator functions of A and B inputs
– A greater-than-or-equal-to B
– A not-equal-to B
– A less-than-or-equal-to B

MachXO2 Family Data Sheet
Ripple mode includes an optional configuration that performs arithmetic using fast carry chain methods. In this configuration (also referred to as CCU2 mode) two additional signals, Carry Generate and Carry Propagate, are generated on a per-slice basis to allow fast arithmetic functions to be constructed by concatenating slices.
RAM Mode
In this mode, a 16x4-bit distributed single port RAM (SPR) can be constructed by using each LUT block in Slice 0
and Slice 1 as a 16x1-bit memory. Slice 2 is used to provide memory address and control signals. A 16x2-bit
Pseudo Dual Port RAM (PDPR) memory is created by using one slice as the read-write port and the other companion slice as the read-only port.
MachXO2 devices support distributed memory initialization.
The Lattice design tools support the creation of a variety of different size memories. Where appropriate, the software will construct these using distributed memory primitives that represent the capabilities of the PFU. Table 2-3
shows the number of slices required to implement different distributed RAM primitives. For more information about
using RAM in MachXO2 devices, please see TN1201, Memory Usage Guide for MachXO2 Devices.
Table 2-3. Number of Slices Required For Implementing Distributed RAM
ROM Mode
ROM mode uses the LUT logic; hence, slices 0-3 can be used in ROM mode. Preloading is accomplished through
the programming interface during PFU configuration.
For more information on the RAM and ROM modes, please refer to TN1201, Memory Usage Guide for MachXO2
Devices.
Routing
There are many resources provided in the MachXO2 devices to route signals individually or as buses with related
control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing) segments.
The inter-PFU connections are made with three different types of routing resources: x1 (spans two PFUs), x2
(spans three PFUs) and x6 (spans seven PFUs). The x1, x2, and x6 connections provide fast and efficient connections in the horizontal and vertical directions.
The design tools take the output of the synthesis tool and places and routes the design. Generally, the place and
route tool is completely automatic, although an interactive routing editor is available to optimize the design.
Clock/Control Distribution Network
Each MachXO2 device has eight clock inputs (PCLK [T, C] [Banknum]_[2..0]) – three pins on the left side, two pins
each on the bottom and top sides and one pin on the right side. These clock inputs drive the clock nets. These
eight inputs can be differential or single-ended and may be used as general purpose I/O if they are not used to
drive the clock nets. When using a single ended clock input, only the PCLKT input can drive the clock tree directly.
The MachXO2 architecture has three types of clocking resources: edge clocks, primary clocks and secondary high
fanout nets. MachXO2-640U, MachXO2-1200/U and higher density devices have two edge clocks each on the top
and bottom edges. Lower density devices have no edge clocks. Edge clocks are used to clock I/O registers and
have low injection time and skew. Edge clock inputs are from PLL outputs, primary clock pads, edge clock bridge
outputs and CIB sources.

Note: SPR = Single Port RAM, PDPR = Pseudo Dual Port RAM2-6
Architecture
MachXO2 Family Data Sheet
The eight primary clock lines in the primary clock network drive throughout the entire device and can provide clocks
for all resources within the device including PFUs, EBRs and PICs. In addition to the primary clock signals,
MachXO2 devices also have eight secondary high fanout signals which can be used for global control signals, such
as clock enables, synchronous or asynchronous clears, presets, output enables, etc. Internal logic can drive the
global clock network for internally-generated global clocks and control signals.
The maximum frequency for the primary clock network is shown in the MachXO2 External Switching Characteristics table.
The primary clock signals for the MachXO2-256 and MachXO2-640 are generated from eight 17:1 muxes The
available clock sources include eight I/O sources and 9 routing inputs. Primary clock signals for the MachXO2-
640U, MachXO2-1200/U and larger devices are generated from eight 27:1 muxes The available clock sources
include eight I/O sources, 11 routing inputs, eight clock divider inputs and up to eight sysCLOCK PLL outputs.

Eight secondary high fanout nets are generated from eight 8:1 muxes as shown in Figure 2-6. One of the eight
inputs to the secondary high fanout net input mux comes from dual function clock pins and the remaining seven
come from internal routing. The maximum frequency for the secondary clock network is shown in MachXO2 External Switching Characteristics table.
Figure 2-6. Secondary High Fanout Nets for MachXO2 Devices
sysCLOCK Phase Locked Loops (PLLs)
The sysCLOCK PLLs provide the ability to synthesize clock frequencies. The MachXO2-640U, MachXO2-1200/U
and larger devices have one or more sysCLOCK PLL. CLKI is the reference frequency input to the PLL and its
source can come from an external I/O pin or from internal routing. CLKFB is the feedback signal to the PLL which
can come from internal routing or an external I/O pin. The feedback divider is used to multiply the reference frequency and thus synthesize a higher frequency clock output.
The MachXO2 sysCLOCK PLLs support high resolution (16-bit) fractional-N synthesis. Fractional-N frequency synthesis allows the user to generate an output clock which is a non-integer multiple of the input frequency. For more
information about using the PLL with Fractional-N synthesis, please see TN1199, MachXO2 sysCLOCK PLL
Design and Usage Guide.
Each output has its own output divider, thus allowing the PLL to generate different frequencies for each output. The
output dividers can have a value from 1 to 128. The CLKOS2 and CLKOS3 dividers may also be cascaded together
to generate low frequency clocks. The CLKOP, CLKOS, CLKOS2, and CLKOS3 outputs can all be used to drive the
MachXO2 clock distribution network directly or general purpose routing resources can be used.

detected. A block diagram of the PLL is shown in Figure 2-7.
The setup and hold times of the device can be improved by programming a phase shift into the CLKOS, CLKOS2,
and CLKOS3 output clocks which will advance or delay the output clock with reference to the CLKOP output clock.
This phase shift can be either programmed during configuration or can be adjusted dynamically. In dynamic mode,
the PLL may lose lock after a phase adjustment on the output used as the feedback source and not relock until the
t
LOCK parameter has been satisfied.
The MachXO2 also has a feature that allows the user to select between two different reference clock sources
dynamically. This feature is implemented using the PLLREFCS primitive. The timing parameters for the PLL are
shown in the table.
The MachXO2 PLL contains a WISHBONE port feature that allows the PLL settings, including divider values, to be
dynamically changed from the user logic. When using this feature the EFB block must also be instantiated in the
design to allow access to the WISHBONE ports. Similar to the dynamic phase adjustment, when PLL settings are
updated through the WISHBONE port the PLL may lose lock and not relock until the tLOCK parameter has been satisfied. The timing parameters for the PLL are shown in the table.
For more details on the PLL and the WISHBONE interface, see TN1199, MachXO2 sysCLOCK PLL Design and
Usage Guide.

sysMEM Embedded Block RAM Memory
The MachXO2-640/U and larger devices contain sysMEM Embedded Block RAMs (EBRs). The EBR consists of a
9-Kbit RAM, with dedicated input and output registers. This memory can be used for a wide variety of purposes
including data buffering, PROM for the soft processor and FIFO.
sysMEM Memory Block
The sysMEM block can implement single port, dual port, pseudo dual port, or FIFO memories. Each block can be
used in a variety of depths and widths as shown in Table 2-5.

Bus Size Matching
All of the multi-port memory modes support different widths on each of the ports. The RAM bits are mapped LSB
word 0 to MSB word 0, LSB word 1 to MSB word 1, and so on. Although the word size and number of words for
each port varies, this mapping scheme applies to each port.
RAM Initialization and ROM Operation
If desired, the contents of the RAM can be pre-loaded during device configuration. EBR initialization data can be
loaded from the UFM. To maximize the number of UFM bits, initialize the EBRs used in your design to an all-zero
pattern. Initializing to an all-zero pattern does not use up UFM bits. MachXO2 devices have been designed such
that multiple EBRs share the same initialization memory space if they are initialized to the same pattern.
By preloading the RAM block during the chip configuration cycle and disabling the write controls, the sysMEM block
can also be utilized as a ROM.
Memory Cascading
Larger and deeper blocks of RAM can be created using EBR sysMEM Blocks. Typically, the Lattice design tools
cascade memory transparently, based on specific design inputs.
Single, Dual, Pseudo-Dual Port and FIFO Modes
Figure 2-8 shows the five basic memory configurations and their input/output names. In all the sysMEM RAM
modes, the input data and addresses for the ports are registered at the input of the memory array. The output data
of the memory is optionally registered at the memory array output.

MachXO2 Family Data Sheet
The EBR memory supports three forms of write behavior for single or dual port operation:
1. Normal – Data on the output appears only during the read cycle. During a write cycle, the data (at the current
address) does not appear on the output. This mode is supported for all data widths.
2. Write Through – A copy of the input data appears at the output of the same port. This mode is supported for
all data widths.
3. Read-Before-Write – When new data is being written, the old contents of the address appears at the output.
FIFO Configuration
The FIFO has a write port with data-in, CEW, WE and CLKW signals. There is a separate read port with data-out,
RCE, RE and CLKR signals. The FIFO internally generates Almost Full, Full, Almost Empty and Empty Flags. The
Full and Almost Full flags are registered with CLKW. The Empty and Almost Empty flags are registered with CLKR.
Table 2-7 shows the range of programming values for these flags.
Table 2-7. Programmable FIFO Flag Ranges
The FIFO state machine supports two types of reset signals: RST and RPRST. The RST signal is a global reset
that clears the contents of the FIFO by resetting the read/write pointer and puts the FIFO flags in their initial reset
state. The RPRST signal is used to reset the read pointer. The purpose of this reset is to retransmit the data that is
in the FIFO. In these applications it is important to keep careful track of when a packet is written into or read from
the FIFO.
Memory Core Reset
The memory core contains data output latches for ports A and B. These are simple latches that can be reset synchronously or asynchronously. RSTA and RSTB are local signals, which reset the output latches associated with
port A and port B respectively. The Global Reset (GSRN) signal resets both ports. The output data latches and
associated resets for both ports are as shown in Figure 2-9.

Devices.
EBR Asynchronous Reset
EBR asynchronous reset or GSR (if used) can only be applied if all clock enables are low for a clock cycle before
the reset is applied and released a clock cycle after the reset is released, as shown in Figure 2-10. The GSR input
to the EBR is always asynchronous.
Figure 2-10. EBR Asynchronous Reset (Including GSR) Timing Diagram
If all clock enables remain enabled, the EBR asynchronous reset or GSR may only be applied and released after
the EBR read and write clock inputs are in a steady state condition for a minimum of 1/fMAX (EBR clock). The reset
release must adhere to the EBR synchronous reset setup time before the next active read or write clock edge.
If an EBR is pre-loaded during configuration, the GSR input must be disabled or the release of the GSR during
device wake up must occur before the release of the device I/Os becoming active.
These instructions apply to all EBR RAM, ROM and FIFO implementations. For the EBR FIFO mode, the GSR signal is always enabled and the WE and RE signals act like the clock enable signals in Figure 2-10. The reset timing
rules apply to the RPReset input versus the RE input and the RST input versus the WE and RE inputs. Both RST
and RPReset are always asynchronous EBR inputs. For more details refer to TN1201, Memory Usage Guide for
MachXO2 Devices.
Note that there are no reset restrictions if the EBR synchronous reset is used and the EBR GSR input is disabled.
Programmable I/O Cells (PIC)
The programmable logic associated with an I/O is called a PIO. The individual PIO are connected to their respective sysIO buffers and pads. On the MachXO2 devices, the PIO cells are assembled into groups of four PIO cells
called a Programmable I/O Cell or PIC. The PICs are placed on all four sides of the device.
On all the MachXO2 devices, two adjacent PIOs can be combined to provide a complementary output driver pair.
The MachXO2-640U, MachXO2-1200/U and higher density devices contain enhanced I/O capability. All PIO pairs
on these larger devices can implement differential receivers. Half of the PIO pairs on the top edge of these devices
can be configured as true LVDS transmit pairs. The PIO pairs on the bottom edge of these higher density devices
have on-chip differential termination and also provide PCI support.

PIO
The PIO contains three blocks: an input register block, output register block and tri-state register block. These
blocks contain registers for operating in a variety of modes along with the necessary clock and selection logic.
Table 2-8. PIO Signal List
Input Register Block
The input register blocks for the PIOs on all edges contain delay elements and registers that can be used to condition high-speed interface signals before they are passed to the device core. In addition to this functionality, the input
register blocks for the PIOs on the right edge include built-in logic to interface to DDR memory.
Figure 2-12 shows the input register block for the PIOs located on the left, top and bottom edges. Figure 2-13
shows the input register block for the PIOs on the right edge.
Left, Top, Bottom Edges
Input signals are fed from the sysIO buffer to the input register block (as signal D). If desired, the input signal can
bypass the register and delay elements and be used directly as a combinatorial signal (INDD), and a clock (INCK).
If an input delay is desired, users can select a fixed delay. I/Os on the bottom edge also have a dynamic delay,
DEL[4:0]. The delay, if selected, reduces input register hold time requirements when using a global clock. The input
block allows two modes of operation. In single data rate (SDR) the data is registered with the system clock (SCLK)
by one of the registers in the single data rate sync register block. In Generic DDR mode, two registers are used to
sample the data on the positive and negative edges of the system clock (SCLK) signal, creating two data streams.

Right Edge
The input register block on the right edge is a superset of the same block on the top, bottom, and left edges. In
addition to the modes described above, the input register block on the right edge also supports DDR memory
mode.
In DDR memory mode, two registers are used to sample the data on the positive and negative edges of the modified DQS (DQSR90) in the DDR Memory mode creating two data streams. Before entering the core, these two data
streams are synchronized to the system clock to generate two data streams.
The signal DDRCLKPOL controls the polarity of the clock used in the synchronization registers. It ensures adequate timing when data is transferred to the system clock domain from the DQS domain. The DQSR90 and
DDRCLKPOL signals are generated in the DQS read-write block.

In DDR generic mode, D0 and D1 inputs are fed into registers on the positive edge of the clock. At the next falling
edge the registered D1 input is registered into the register Q1. A multiplexer running off the same clock is used to
switch the mux between the outputs of registers Q0 and Q1 that will then feed the output.

Right Edge
The output register block on the right edge is a superset of the output register on left, top and bottom edges of the
device. In addition to supporting SDR and Generic DDR modes, the output register blocks for PIOs on the right
edge include additional logic to support DDR-memory interfaces. Operation of this block is similar to that of the output register block on other edges.
In DDR memory mode, D0 and D1 inputs are fed into registers on the positive edge of the clock. At the next falling
edge the registered D1 input is registered into the register Q1. A multiplexer running off the DQSW90 signal is used
to switch the mux between the outputs of registers Q0 and Q1 that will then feed the output.

Tri-state Register Block
The tri-state register block registers tri-state control signals from the core of the device before they are passed to
the sysIO buffers. The block contains a register for SDR operation. In SDR, TD input feeds one of the flip-flops that
then feeds the output.
The tri-state register blocks on the right edge contain an additional register for DDR memory operation. In DDR
memory mode, the register TS input is fed into another register that is clocked using the DQSW90 signal. The output of this register is used as a tri-state control.
Input Gearbox
Each PIC on the bottom edge has a built-in 1:8 input gearbox. Each of these input gearboxes may be programmed
as a 1:7 de-serializer or as one IDDRX4 (1:8) gearbox or as two IDDRX2 (1:4) gearboxes. Table 2-9 shows the

Certain PICs on the right edge of MachXO2-640U, MachXO2-1200/U and larger devices, have additional circuitry
to allow the implementation of DDR memory interfaces. There are two groups of 14 or 12 PIOs each on the right

to 16-bit wide memory interfaces. One PIO from each group contains a control element, the DQS Read/Write

Block, to facilitate the generation of clock and control signals (DQSR90, DQSW90, DDRCLKPOL and DATAVALID).
These clock and control signals are distributed to the other PIO in the group through dedicated low skew routing.
DQS Read Write Block
Source synchronous interfaces generally require the input clock to be adjusted in order to correctly capture data at
the input register. For most interfaces a PLL is used for this adjustment. However, in DDR memories the clock
(referred to as DQS) is not free-running so this approach cannot be used. The DQS Read Write block provides the
required clock alignment for DDR memory interfaces. DQSR90 and DQSW90 signals are generated by the DQS
Read Write block from the DQS input.
In a typical DDR memory interface design, the phase relationship between the incoming delayed DQS strobe and
the internal system clock (during the read cycle) is unknown. The MachXO2 family contains dedicated circuits to
transfer data between these domains. To prevent set-up and hold violations, at the domain transfer between DQS
(delayed) and the system clock, a clock polarity selector is used. This circuit changes the edge on which the data is
registered in the synchronizing registers in the input register block. This requires evaluation at the start of each
read cycle for the correct clock polarity. Prior to the read operation in DDR memories, DQS is in tri-state (pulled by
termination). The DDR memory device drives DQS low at the start of the preamble state. A dedicated circuit in the
DQS Read Write block detects the first DQS rising edge after the preamble state and generates the DDRCLKPOL
signal. This signal is used to control the polarity of the clock to the synchronizing registers.
The temperature, voltage and process variations of the DQS delay block are compensated by a set of calibration
signals (6-bit bus) from a DLL on the right edge of the device. The DLL loop is compensated for temperature, voltage and process variations by the system clock and feedback loop.
sysIO Buffer
Each I/O is associated with a flexible buffer referred to as a sysIO buffer. These buffers are arranged around the
periphery of the device in groups referred to as banks. The sysIO buffers allow users to implement a wide variety of
standards that are found in today’s systems including LVCMOS, TTL, PCI, SSTL, HSTL, LVDS, BLVDS, MLVDS
and LVPECL.
Each bank is capable of supporting multiple I/O standards. In the MachXO2 devices, single-ended output buffers,
ratioed input buffers (LVTTL, LVCMOS and PCI), differential (LVDS) and referenced input buffers (SSTL and HSTL)
are powered using I/O supply voltage (VCCIO). Each sysIO bank has its own VCCIO. In addition, each bank has a
voltage reference, VREF, which allows the use of referenced input buffers independent of the bank VCCIO.
MachXO2-256 and MachXO2-640 devices contain single-ended ratioed input buffers and single-ended output buffers with complementary outputs on all the I/O banks. Note that the single-ended input buffers on these devices do
not contain PCI clamps. In addition to the single-ended I/O buffers these two devices also have differential and referenced input buffers on all I/Os. The I/Os are arranged in pairs, the two pads in the pair are described as “T” and
“C”, where the true pad is associated with the positive side of the differential input buffer and the comp (complementary) pad is associated with the negative side of the differential input buffer.
MachXO2-640U, MachXO2-1200/U, MachXO2-2000/U, MachXO2-4000 and MachXO2-7000 devices contain three
types of sysIO buffer pairs.
1. Left and Right sysIO Buffer Pairs
The sysIO buffer pairs in the left and right banks of the device consist of two single-ended output drivers and
two single-ended input buffers (for ratioed inputs such as LVCMOS and LVTTL). The I/O pairs on the left and
right of the devices also have differential and referenced input buffers.
2. Bottom sysIO Buffer Pairs
The sysIO buffer pairs in the bottom bank of the device consist of two single-ended output drivers and two single-ended input buffers (for ratioed inputs such as LVCMOS and LVTTL). The I/O pairs on the bottom also have
differential and referenced input buffers. Only the I/Os on the bottom banks have programmable PCI clamps 2-23
Architecture
MachXO2 Family Data Sheet
and differential input termination. The PCI clamp is enabled after VCC and VCCIO are at valid operating levels
and the device has been configured.
3. Top sysIO Buffer Pairs
The sysIO buffer pairs in the top bank of the device consist of two single-ended output drivers and two singleended input buffers (for ratioed inputs such as LVCMOS and LVTTL). The I/O pairs on the top also have differential and referenced I/O buffers. Half of the sysIO buffer pairs on the top edge have true differential outputs.
The sysIO buffer pair comprising of the A and B PIOs in every PIC on the top edge have a differential output
driver. The referenced input buffer can also be configured as a differential input buffer.
Typical I/O Behavior During Power-up
The internal power-on-reset (POR) signal is deactivated when VCC and VCCIO0 have reached VPORUP level defined
in the Power-On-Reset Voltage table in the DC and Switching Characteristics section of this data sheet. After the
POR signal is deactivated, the FPGA core logic becomes active. It is the user’s responsibility to ensure that all
V
CCIO banks are active with valid input logic levels to properly control the output logic states of all the I/O banks that
are critical to the application. The default configuration of the I/O pins in a blank device is tri-state with a weak pulldown to GND (some pins such as PROGRAMN and the JTAG pins have weak pull-up to VCCIO as the default functionality). The I/O pins will maintain the blank configuration until VCC and VCCIO (for I/O banks containing configuration I/Os) have reached VPORUP levels at which time the I/Os will take on the user-configured settings only after a
proper download/configuration.
There are various ways a user can ensure that there are no spurious signals on critical outputs as the device powers up. These are discussed in more detail in TN1202, MachXO2 sysIO Usage Guide.
Supported Standards
The MachXO2 sysIO buffer supports both single-ended and differential standards. Single-ended standards can be
further subdivided into LVCMOS, LVTTL, and PCI. The buffer supports the LVTTL, PCI, LVCMOS 1.2, 1.5, 1.8, 2.5,
and 3.3V standards. In the LVCMOS and LVTTL modes, the buffer has individually configurable options for drive
strength, bus maintenance (weak pull-up, weak pull-down, bus-keeper latch or none) and open drain. BLVDS,
MLVDS and LVPECL output emulation is supported on all devices. The MachXO2-640U, MachXO2-1200/U and
higher devices support on-chip LVDS output buffers on approximately 50% of the I/Os on the top bank. Differential
receivers for LVDS, BLVDS, MLVDS and LVPECL are supported on all banks of MachXO2 devices. PCI support is
provided in the bottom bank of theMachXO2-640U, MachXO2-1200/U and higher density devices. Table 2-11 summarizes the I/O characteristics of the MachXO2 PLDs.
Tables 2-11 and 2-12 show the I/O standards (together with their supply and reference voltages) supported by the
MachXO2 devices. For further information on utilizing the sysIO buffer to support a variety of standards please see

Hot Socketing
The MachXO2 devices have been carefully designed to ensure predictable behavior during power-up and powerdown. Leakage into I/O pins is controlled to within specified limits. This allows for easy integration with the rest of
the system. These capabilities make the MachXO2 ideal for many multiple power supply and hot-swap applications.
On-chip Oscillator
Every MachXO2 device has an internal CMOS oscillator. The oscillator output can be routed as a clock to the clock
tree or as a reference clock to the sysCLOCK PLL using general routing resources. The oscillator frequency can be
divided by internal logic. There is a dedicated programming bit and a user input to enable/disable the oscillator. The
oscillator frequency ranges from 2.08 MHz to 133 MHz. The software default value of the Master Clock (MCLK) is
nominally 2.08 MHz. When a different MCLK is selected during the design process, the following sequence takes
place:
1. Device powers up with a nominal MCLK frequency of 2.08 MHz.
2. During configuration, users select a different master clock frequency.
3. The MCLK frequency changes to the selected frequency once the clock configuration bits are received.
4. If the user does not select a master clock frequency, then the configuration bitstream defaults to the MCLK frequency of 2.08 MHz.
Table 2-14 lists all the available MCLK frequencies.
Table 2-14. Available MCLK Frequencies
Embedded Hardened IP Functions and User Flash Memory
All MachXO2 devices provide embedded hardened functions such as SPI, I2
C and Timer/Counter. MachXO2-640/U
and higher density devices also provide User Flash Memory (UFM). These embedded blocks interface through the
WISHBONE interface with routing as shown in Figure 2-20.

Hardened I2
C IP Core
Every MachXO2 device contains two I2
C IP cores. These are the primary and secondary I2
C IP cores. Either of the
two cores can be configured either as an I2
C master or as an I2
C slave. The only difference between the two IP
cores is that the primary core has pre-assigned I/O pins whereas users can assign I/O pins for the secondary core.
When the IP core is configured as a master it will be able to control other devices on the I2
C bus through the interface. When the core is configured as the slave, the device will be able to provide I/O expansion to an I2
C Master.
The I2
C cores support the following functionality:
• Master and Slave operation
• 7-bit and 10-bit addressing
• Multi-master arbitration support
• Clock stretching
• Up to 400 KHz data transfer speed
• General call support
• Interface to custom logic through 8-bit WISHBONE interface

User Flash Memory (UFM)
MachXO2-640/U and higher density devices provide a User Flash Memory block, which can be used for a variety of
applications including storing a portion of the configuration image, initializing EBRs, to store PROM data or, as a
general purpose user Flash memory. The UFM block connects to the device core through the embedded function
block WISHBONE interface. Users can also access the UFM block through the JTAG, I2
C and SPI interfaces of the
device. The UFM block offers the following features:
• Non-volatile storage up to 256Kbits
• 100K write cycles
• Write access is performed page-wise; each page has 128 bits (16 bytes)
• Auto-increment addressing
• WISHBONE interface
For more information on the UFM, please refer to TN1205, Using User Flash Memory and Hardened Control Functions in MachXO2 Devices.
Standby Mode and Power Saving Options
MachXO2 devices are available in three options for maximum flexibility: ZE, HC and HE devices. The ZE devices
have ultra low static and dynamic power consumption. These devices use a 1.2V core voltage that further reduces
power consumption. The HC and HE devices are designed to provide high performance. The HC devices have a
built-in voltage regulator to allow for 2.5V VCC and 3.3V VCC while the HE devices operate at 1.2V VCC.
MachXO2 devices have been designed with features that allow users to meet the static and dynamic power
requirements of their applications by controlling various device subsystems such as the bandgap, power-on-reset
circuitry, I/O bank controllers, power guard, on-chip oscillator, PLLs, etc. In order to maximize power savings,
MachXO2 devices support an ultra low power Stand-by mode. While most of these features are available in all
three device types, these features are mainly intended for use with MachXO2 ZE devices to manage power consumption.
In the stand-by mode the MachXO2 devices are powered on and configured. Internal logic, I/Os and memories are
switched on and remain operational, as the user logic waits for an external input. The device enters this mode
when the standby input of the standby controller is toggled or when an appropriate I2
C or JTAG instruction is issued
by an external master. Various subsystems in the device such as the band gap, power-on-reset circuitry etc can be
configured such that they are automatically turned “off” or go into a low power consumption state to save power
when the device enters this state.2-33
Architecture
MachXO2 Family Data Sheet
Table 2-18. MachXO2 Power Saving Features Description
For more details on the standby mode refer to TN1198, Power Estimation and Management for MachXO2 Devices.
Power On Reset
MachXO2 devices have power-on reset circuitry to monitor VCCINT and VCCIO voltage levels during power-up and
operation. At power-up, the POR circuitry monitors VCCINT and VCCIO0 (controls configuration) voltage levels. It
then triggers download from the on-chip configuration Flash memory after reaching the VPORUP level specified in
the Power-On-Reset Voltage table in the DC and Switching Characteristics section of this data sheet. For devices
without voltage regulators (ZE and HE devices), VCCINT is the same as the VCC supply voltage. For devices with
voltage regulators (HC devices), VCCINT is regulated from the VCC supply voltage. From this voltage reference, the
time taken for configuration and entry into user mode is specified as Flash Download Time (tREFRESH) in the DC
and Switching Characteristics section of this data sheet. Before and during configuration, the I/Os are held in tristate. I/Os are released to user functionality once the device has finished configuration. Note that for HC devices, a
separate POR circuit monitors external VCC voltage in addition to the POR circuit that monitors the internal postregulated power supply voltage level.
Once the device enters into user mode, the POR circuitry can optionally continue to monitor VCCINT levels. If
V
CCINT drops below VPORDNBG level (with the bandgap circuitry switched on) or below VPORDNSRAM level (with the
bandgap circuitry switched off to conserve power) device functionality cannot be guaranteed. In such a situation
the POR issues a reset and begins monitoring the VCCINT and VCCIO voltage levels. VPORDNBG and VPORDNSRAM
are both specified in the Power-On-Reset Voltage table in the DC and Switching Characteristics section of this data
sheet.
Note that once a ZE or HE device enters user mode, users can switch off the bandgap to conserve power. When
the bandgap circuitry is switched off, the POR circuitry also shuts down. The device is designed such that a minimal, low power POR circuit is still operational (this corresponds to the VPORDNSRAM reset point described in the
paragraph above). However this circuit is not as accurate as the one that operates when the bandgap is switched
on. The low power POR circuit emulates an SRAM cell and is biased to trip before the vast majority of SRAM cells
flip. If users are concerned about the VCC supply dropping below VCC (min) they should not shut down the bandgap
or POR circuit.
Device Subsystem Feature Description
Bandgap
The bandgap can be turned off in standby mode. When the Bandgap is turned off, analog circuitry such as the POR, PLLs, on-chip oscillator, and referenced and differential
I/O buffers are also turned off. Bandgap can only be turned off for 1.2V devices.
Power-On-Reset (POR)
The POR can be turned off in standby mode. This monitors VCC levels. In the event of
unsafe VCC drops, this circuit reconfigures the device. When the POR circuitry is turned
off, limited power detector circuitry is still active. This option is only recommended for applications in which the power supply rails are reliable.
On-Chip Oscillator The on-chip oscillator has two power saving features. It may be switched off if it is not
needed in your design. It can also be turned off in Standby mode.
PLL
Similar to the on-chip oscillator, the PLL also has two power saving features. It can be
statically switched off if it is not needed in a design. It can also be turned off in Standby
mode. The PLL will wait until all output clocks from the PLL are driven low before powering off.
I/O Bank Controller
Referenced and differential I/O buffers (used to implement standards such as HSTL,
SSTL and LVDS) consume more than ratioed single-ended I/Os such as LVCMOS and
LVTTL. The I/O bank controller allows the user to turn these I/Os off dynamically on a
per bank selection.
Dynamic Clock Enable for Primary
Clock Nets Each primary clock net can be dynamically disabled to save power.
Power Guard
Power Guard is a feature implemented in input buffers. This feature allows users to
switch off the input buffer when it is not needed. This feature can be used in both clock
and data paths. Its biggest impact is that in the standby mode it can be used to switch off
clock inputs that are distributed using general routing resources.2-34
Architecture
MachXO2 Family Data Sheet
Configuration and Testing
This section describes the configuration and testing features of the MachXO2 family.
IEEE 1149.1-Compliant Boundary Scan Testability
All MachXO2 devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant test access
port (TAP). This allows functional testing of the circuit board, on which the device is mounted, through a serial scan
path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in
and loaded directly onto test nodes, or test data to be captured and shifted out for verification. The test access port
consists of dedicated I/Os: TDI, TDO, TCK and TMS. The test access port shares its power supply with VCCIO
Bank 0 and can operate with LVCMOS3.3, 2.5, 1.8, 1.5, and 1.2 standards.
For more details on boundary scan test, see AN8066, Boundary Scan Testability with Lattice sysIO Capability and
TN1087, Minimizing System Interruption During Configuration Using TransFR Technology.
Device Configuration
All MachXO2 devices contain two ports that can be used for device configuration. The Test Access Port (TAP),
which supports bit-wide configuration and the sysCONFIG port which supports serial configuration through I2
C or
SPI. The TAP supports both the IEEE Standard 1149.1 Boundary Scan specification and the IEEE Standard 1532
In-System Configuration specification. There are various ways to configure a MachXO2 device:
1. Internal Flash Download
2. JTAG
3. Standard Serial Peripheral Interface (Master SPI mode) – interface to boot PROM memory
4. System microprocessor to drive a serial slave SPI port (SSPI mode)
5. Standard I2
C Interface to system microprocessor
Upon power-up, the configuration SRAM is ready to be configured using the selected sysCONFIG port. Once a
configuration port is selected, it will remain active throughout that configuration cycle. The IEEE 1149.1 port can be
activated any time after power-up by sending the appropriate command through the TAP port. Optionally the device can run a CRC check upon entering the user mode. This will ensure that the device was configured correctly.
The sysCONFIG port has 10 dual-function pins which can be used as general purpose I/Os if they are not required
for configuration. See TN1204, MachXO2 Programming and Configuration Usage Guide for more information
about using the dual-use pins as general purpose I/Os.
Lattice design software uses proprietary compression technology to compress bit-streams for use in MachXO2
devices. Use of this technology allows Lattice to provide a lower cost solution. In the unlikely event that this technology is unable to compress bitstreams to fit into the amount of on-chip Flash memory, there are a variety of techniques that can be utilized to allow the bitstream to fit in the on-chip Flash memory. For more details, refer to
TN1204, MachXO2 Programming and Configuration Usage Guide.
The Test Access Port (TAP) has five dual purpose pins (TDI, TDO, TMS and TCK). These pins are dual function
pins - TDI, TDO, TMS and TCK can be used as general purpose I/O if desired. For more details, refer to TN1204,
MachXO2 Programming and Configuration Usage Guide.
TransFR (Transparent Field Reconfiguration)
TransFR is a unique Lattice technology that allows users to update their logic in the field without interrupting system operation using a simple push-button solution. For more details refer to TN1087, Minimizing System Interruption During Configuration Using TransFR Technology for details.
Security and One-Time Programmable Mode (OTP)2-35
Architecture
MachXO2 Family Data Sheet
For applications where security is important, the lack of an external bitstream provides a solution that is inherently
more secure than SRAM-based FPGAs. This is further enhanced by device locking. MachXO2 devices contain
security bits that, when set, prevent the readback of the SRAM configuration and non-volatile Flash memory
spaces. The device can be in one of two modes:
1. Unlocked – Readback of the SRAM configuration and non-volatile Flash memory spaces is allowed.
2. Permanently Locked – The device is permanently locked.
Once set, the only way to clear the security bits is to erase the device. To further complement the security of the
device, a One Time Programmable (OTP) mode is available. Once the device is set in this mode it is not possible to
erase or re-program the Flash and SRAM OTP portions of the device. For more details, refer to TN1204, MachXO2
Programming and Configuration Usage Guide.
Dual Boot
MachXO2 devices can optionally boot from two patterns, a primary bitstream and a golden bitstream. If the primary
bitstream is found to be corrupt while being downloaded into the SRAM, the device shall then automatically re-boot
from the golden bitstream. Note that the primary bitstream must reside in the on-chip Flash. The golden image
MUST reside in an external SPI Flash. For more details, refer to TN1204, MachXO2 Programming and Configuration Usage Guide.
Soft Error Detection
The SED feature is a CRC check of the SRAM cells after the device is configured. This check ensures that the
SRAM cells were configured successfully. This feature is enabled by a configuration bit option. The Soft Error
Detection can also be initiated in user mode via an input to the fabric. The clock for the Soft Error Detection circuit
is generated using a dedicated divider. The undivided clock from the on-chip oscillator is the input to this divider.
For low power applications users can switch off the Soft Error Detection circuit. For more details, refer to TN1206,
MachXO2 Soft Error Detection Usage Guide.
TraceID
Each MachXO2 device contains a unique (per device), TraceID that can be used for tracking purposes or for IP
security applications. The TraceID is 64 bits long. Eight out of 64 bits are user-programmable, the remaining 56 bits
are factory-programmed. The TraceID is accessible through the EFB WISHBONE interface and can also be
accessed through the SPI, I2
C, or JTAG interfaces.
Density Shifting
The MachXO2 family has been designed to enable density migration within the same package. Furthermore, the
architecture ensures a high success rate when performing design migration from lower density devices to higher
density devices. In many cases, it is also possible to shift a lower utilization design targeted for a high-density
device to a lower density device. However, the exact details of the final resource utilization will impact the likely success in each case. For more details refer to the MachXO2 migration files.www.latticesemi.com 3-1 DS1035 DC and Switching_01.8

1. Exact performance may vary with device and design implementation. Commercial timing numbers are shown at 85°C and 1.14V. Other
operating conditions, including industrial, can be extracted from the Diamond software.
2. General I/O timing numbers based on LVCMOS 2.5, 8mA, 0pf load.
3. Generic DDR timing numbers based on LVDS I/O (for input, output, and clock ports).
4. DDR timing numbers based on SSTL25. DDR2 timing numbers based on SSTL18. LPDDR timing numbers based in LVCMOS18.
5. 7:1 LVDS (GDDR71) uses the LVDS I/O standard (for input, output, and clock ports).
6. For Generic DDRX1 mode tSU = tHO = (tDVE - tDVA - 0.03ns)/2.
7. The tSU_DEL and tH_DEL values use the SCLK_ZERHOLD default step size. Each step is 105ps (-6), 113ps (-5), 120ps (-4).
8. This number for general purpose usage. Duty cycle tolerance is +/-10%.
9. Duty cycle is +/- 5% for system usage.
10. The above timing numbers are generated using the Diamond design tool. Exact performance may vary with the device selected.

1000 cycles. Phase jitter is taken over 2000 cycles. All values per JESD65B.
2. Output clock is valid after tLOCK for PLL reset and dynamic delay adjustment.
3. Using LVDS output buffers.
4. CLKOS as compared to CLKOP output for one phase step at the maximum VCO frequency. See TN1199, MachXO2 sysCLOCK PLL
Design and Usage Guide for more details.
5. At minimum fPFD. As the fPFD increases the time will decrease to approximately 60% the value listed.
6. Maximum allowed jitter on an input clock. PLL unlock may occur if the input jitter exceeds this specification. Jitter on the input clock may be
transferred to the output clocks, resulting in jitter measurements outside the output specifications listed in this table.
7. Edge Duty Trim Accuracy is a percentage of the setting value. Settings available are 70 ps, 140 ps, and 280 ps in addition to the default
value of none.
8. Jitter values measured with the internal oscillator operating. The jitter values will increase with loading of the PLD fabric and in the presence
of SSO noise.

Signal Descriptions
Signal Name I/O Descriptions
General Purpose
P[Edge] [Row/Column
Number]_[A/B/C/D] I/O
[Edge] indicates the edge of the device on which the pad is located. Valid edge designations
are L (Left), B (Bottom), R (Right), T (Top).
[Row/Column Number] indicates the PFU row or the column of the device on which the PIO
Group exists. When Edge is T (Top) or (Bottom), only need to specify Row Number. When
Edge is L (Left) or R (Right), only need to specify Column Number.
[A/B/C/D] indicates the PIO within the group to which the pad is connected.
Some of these user-programmable pins are shared with special function pins. When not used
as special function pins, these pins can be programmed as I/Os for user logic.
During configuration of the user-programmable I/Os, the user has an option to tri-state the
I/Os and enable an internal pull-up, pull-down or buskeeper resistor. This option also applies
to unused pins (or those not bonded to a package pin). The default during configuration is for
user-programmable I/Os to be tri-stated with an internal pull-down resistor enabled. When the
device is erased, I/Os will be tri-stated with an internal pull-down resistor enabled. Some pins,
such as PROGRAMN and JTAG pins, default to tri-stated I/Os with pull-up resistors enabled
when the device is erased.
NC — No connect.
GND — GND – Ground. Dedicated pins. It is recommended that all GNDs are tied together.
VCC — V
CC – The power supply pins for core logic. Dedicated pins. It is recommended that all VCCs
are tied to the same supply.
VCCIOx — VCCIO – The power supply pins for I/O Bank x. Dedicated pins. It is recommended that all
VCCIOs located in the same bank are tied to the same supply.
PLL and Clock Functions (Used as user-programmable I/O pins when not used for PLL or clock pins)
[LOC]_GPLL[T, C]_IN — Reference Clock (PLL) input pads: [LOC] indicates location. Valid designations are L (Left
PLL) and R (Right PLL). T = true and C = complement.
[LOC]_GPLL[T, C]_FB — Optional Feedback (PLL) input pads: [LOC] indicates location. Valid designations are L (Left
PLL) and R (Right PLL). T = true and C = complement.
PCLK [n]_[2:0] — Primary Clock pads. One to three clock pads per side.
Test and Programming (Dual function pins used for test access port and during sysCONFIG™)
TMS I Test Mode Select input pin, used to control the 1149.1 state machine.
TCK I Test Clock input pin, used to clock the 1149.1 state machine.
TDI I Test Data input pin, used to load data into the device using an 1149.1 state machine.
TDO O Output pin – Test Data output pin used to shift data out of the device using 1149.1.
JTAGENB I
Optionally controls behavior of TDI, TDO, TMS, TCK. If the device is configured to use the
JTAG pins (TDI, TDO, TMS, TCK) as general purpose I/O, then:
If JTAGENB is low: TDI, TDO, TMS and TCK can function a general purpose I/O.
If JTAGENB is high: TDI, TDO, TMS and TCK function as JTAG pins.
For more details, refer to TN1204, MachXO2 Programming and Configuration Usage Guide.
Configuration (Dual function pins used during sysCONFIG)
PROGRAMN I Initiates configuration sequence when asserted low. This pin always has an active pull-up.
INITN I/O Open Drain pin. Indicates the FPGA is ready to be configured. During configuration, a pull-up
is enabled.

Thermal Management
Thermal management is recommended as part of any sound FPGA design methodology. To assess the thermal
characteristics of a system, Lattice specifies a maximum allowable junction temperature in all device data sheets.
Users must complete a thermal analysis of their specific design to ensure that the device and package do not
exceed the junction temperature limits. Refer to the Thermal Management document to find the device/package
specific thermal values.
For Further Information
For further information regarding Thermal Management, refer to the following:
• Thermal Management document
• TN1198, Power Estimation and Management for MachXO2 Devices

R1 Device Specifications
The LCMXO2-1200ZE/HC “R1” devices have the same specifications as their Standard (non-R1) counterparts
except as listed below. For more details on the R1 to Standard migration refer to AN8086, Designing for Migration
from MachXO2-1200-R1 to Standard Non-R1) Devices.
• The User Flash Memory (UFM) cannot be programmed through the internal WISHBONE interface. It can still be
programmed through the JTAG/SPI/I2
C ports.
• The on-chip differential input termination resistor value is higher than intended. It is approximately 200 as
opposed to the intended 100. It is recommended to use external termination resistors for differential inputs. The
on-chip termination resistors can be disabled through Lattice design software.
• Soft Error Detection logic may not produce the correct result when it is run for the first time after configuration. To
use this feature, discard the result from the first operation. Subsequent operations will produce the correct result.
• Under certain conditions, IIH exceeds data sheet specifications. The following table provides more details:
• The user SPI interface does not operate correctly in some situations. During master read access and slave write
access, the last byte received does not generate the RRDY interrupt.
• In GDDRX2, GDDRX4 and GDDR71 modes, ECLKSYNC may have a glitch in the output under certain conditions, leading to possible loss of synchronization.
• When using the hard I2
C IP core, the I2
C status registers I2C_1_SR and I2C_2_SR may not update correctly.
• PLL Lock signal will glitch high when coming out of standby. This glitch lasts for about 10µsec before returning
low.
• Dual boot only available on HC devices, requires tying VCC and VCCIO2 to the same 3.3V or 2.5V supply.

Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
REACH is a European Community Regulation on chemicals and their safe use (EC 1907/2006).
It deals with the Registration, Evaluation, Authorisation and Restriction of CHemical
substances. The law entered into force on 1 June 2007. The aim of REACH is to improve the
protection of human health and the environment through the better and earlier identification of
the intrinsic properties of chemical substances. More information may be found at
http://ec.europa.eu/environment/chemicals/reach/reach_intro.htm.
Lattice is a supplier of “articles” as defined in REACH. The “substances” contained in these
articles are not intentionally released, nor do the articles contain any of the substances on the
updated SVHC Candidate List of 138 substances published on December 19, 2012:

Introduction
The LatticeSC family of FPGA combines a high-performance FPGA fabric, high-speed SERDES, high-performance I/Os and large embedded RAM in a single industry leading architecture. This FPGA family is fabricated in a
state of the art technology to provide one of the highest performing FPGAs in the industry.
This family of devices includes features to meet the needs of today’s communication network systems. These features include SERDES with embedded advance PCS (Physical Coding sub-layer), up to 7.8 Mbits of sysMEM
embedded block RAM, dedicated logic to support system level standards such as RAPIDIO, HyperTransport,
SPI4.2, SFI-4, UTOPIA, XGMII and CSIX. The devices in this family feature clock multiply, divide and phase shift
PLLs, numerous DLLs and dynamic glitch free clock MUXs which are required in today’s high end system designs.
High speed, high bandwidth I/O make this family ideal for high throughput systems.
The ispLEVER®
design tool from Lattice allows large complex designs to be efficiently implemented using the LatticeSC family of FPGA devices. Synthesis library support for LatticeSC is available for popular logic synthesis tools.
The ispLEVER tool uses the synthesis tool output along with the constraints from its floor planning tools to place
and route the design in the LatticeSC device. The ispLEVER tool extracts the timing from the routing and backannotates it into the design for timing verification.

Architecture Overview
The LatticeSC architecture contains an array of logic blocks surrounded by Programmable I/O Cells (PIC). Interspersed between the rows of logic blocks are rows of sysMEM Embedded Block RAM (EBR). The upper left and
upper right corners of the devices contain SERDES blocks and their associated PCS blocks, as show in Figure 2-1.
Top left and top right corner of the device contain blocks of SERDES. Each block of SERDES contains four channels (quad). Each channel contains a single serializer and de-serializer, synchronization and word alignment logic.
The SERDES quad connects with Physical Coding Sub-layer (PCS) block that contain logic to simultaneously perform alignment, coding, de-coding and other functions. The SERDES quad block has separate supply, ground and
reference voltage pins.
The PICs contain logic to facilitate the conditioning of signals to and from the I/O before they leave or enter the
FPGA fabric. The block provides DDR and shift register capabilities that act as a gearbox between high speed I/O
and the FPGA fabric. The blocks also contain programmable Adaptive Input Logic that adjusts the delay applied to
signals as they enter the device to optimize setup and hold times and ensure robust performance.
sysMEM EBRs are large dedicated fast memory blocks. They can be configured as RAM, ROM or FIFO. These
blocks have dedicated logic to simplify the implementation of FIFOs.
The PFU, PIC and EBR blocks are arranged in a two-dimensional grid with rows and columns as shown in
Figure 2-1. These blocks are connected with many vertical and horizontal routing channel resources. The place
and route software tool automatically allocates these routing resources.
The corners contain the sysCLOCK Analog Phase Locked Loop (PLL) and Delay Locked Loop (DLL) Blocks. The
PLLs have multiply, divide and phase shifting capability; they are used to manage the phase relationship of the
clocks. The LatticeSC architecture provides eight analog PLLs per device and 12 DLLs. The DLLs provide a simple
delay capability and can also be used to calibrate other delays within the device.
Every device in the family has a JTAG Port with internal Logic Analyzer (ispTRACY) capability. The sysCONFIG™
port which allows for serial or parallel device configuration. The system bus simplifies the connections of the external microprocessor to the device for tasks such as SERDES and PCS configuration or interface to the general
FPGA logic. The LatticeSC devices use 1.2V as their core voltage operation with 1.0V operation also possible.

PFU Blocks
The core of the LatticeSC devices consists of PFU blocks. The PFUs can be programmed to perform Logic, Arithmetic, Distributed RAM and Distributed ROM functions.
Each PFU block consists of four interconnected slices, numbered 0-3 as shown in Figure 2-2. All the interconnections to and from PFU blocks are from routing. There are 53 inputs and 25 outputs associated with each PFU block.
Figure 2-2. PFU Diagram
Slice
Each slice contains two LUT4 lookup tables feeding two registers (programmed to be in FF or Latch mode), and
some associated logic that allows the LUTs to be combined to implement 5, 6, 7 and 8 Input LUTs (LUT5, LUT6,
LUT7 and LUT8). There is control logic to perform set/reset functions (programmable as synchronous/asynchronous), clock select, chip-select and wider RAM/ROM functions. Figure 2-3 shows an overview of the internal logic
of the slice. The registers in the slice can be configured for positive/negative and edge/level clocks.
There are 14 input signals: 13 signals from routing and one from the carry-chain (from adjacent slice or PFU).
There are seven outputs: six to routing and one to carry-chain (to adjacent PFU). Table 2-1 lists the signals associated with each slice.

Modes of Operation
Each Slice is capable of four modes of operation: Logic, Ripple, RAM and ROM. Table 2-2 lists the modes and the
capability of the Slice blocks.
Table 2-2. Slice Modes
Logic Mode
In this mode, the LUTs in each Slice are configured as combinatorial lookup tables. A LUT4 can have 16 possible
input combinations. Any logic function with four inputs can be generated by programming this lookup table. Since
there are two LUT4s per Slice, a LUT5 can be constructed within one Slice. Larger lookup tables such as LUT6,
LUT7 and LUT8 can be constructed by concatenating other Slices in the PFU.
Ripple Mode
Ripple mode allows the efficient implementation of small arithmetic functions. In ripple mode, the following functions can be implemented by each Slice:
• Addition 2-bit
• Subtraction 2-bit
• Up counter 2-bit
• Down counter 2-bit
• Comparator functions of A and B inputs
- A greater-than-or-equal-to B
- A not-equal-to B
- A less-than-or-equal-to B
Two additional signals: Carry Generate and Carry Propagate are generated per Slice in this mode, allowing fast
arithmetic functions to be constructed by concatenating Slices.
RAM Mode
In this mode, distributed RAM can be constructed using each LUT block as a 16x1-bit memory. Through the combination of LUTs and Slices, a variety of different memories can be constructed.
The Lattice design tools support the creation of a variety of different size memories. Where appropriate, the software will construct these using distributed memory primitives that represent the capabilities of the Slice. Table 2-3
shows the number of Slices required to implement different distributed RAM primitives. Dual port memories involve
the pairing of two Slices, one Slice functions as the read-write port. The other companion Slice supports the readonly port. For more information on RAM mode, please see details of additional technical documentation at the end
of this data sheet.
Table 2-3. Number of Slices Required For Implementing Distributed RAM
ROM Mode
The ROM mode uses the same principal as the RAM modes, but without the Write port. Pre-loading is accomplished through the programming interface during configuration.

PFU Modes of Operation
Slices can be combined within a PFU to form larger functions. Table 2-4 tabulates these modes and documents the
functionality possible at the PFU level.
Table 2-4. PFU Modes of Operation
Routing
There are many resources provided in the LatticeSC devices to route signals individually or as busses with related
control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing) segments.
The inter-PFU connections are made with x1 (spans two PFU), x2 (spans three PFU) and x6 (spans seven PFU)
resources. The x1 and x2 connections provide fast and efficient connections in horizontal, vertical and diagonal
directions. All connections are buffered to ensure high-speed operation even with long high-fanout connections.
The ispLEVER design tool takes the output of the synthesis tool and places and routes the design. Generally, the
place and route tool is completely automatic, although an interactive routing editor is available to optimize the
design.
sysCLOCK Network
The LatticeSC devices have three distinct clock networks for use in distributing high-performance clocks within the
device, primary clocks, secondary clocks and edge clocks. In addition to these dedicated clock networks, users are
free to route clocks within the device using the general purpose routing. Figure 2-4 shows the clock resources
available to each slice.

Primary Clock Routing
The clock routing structure in LatticeSC devices consists of 12 Primary Clock lines per quadrant. The primary
clocks are generated from 64:1 MUXs located in each quadrant. Three of the inputs to each 64:1 MUX comes from
local routing, one is connected to GND and rest of the 60 inputs are from the primary clock sources. Figure 2-6

Secondary Clocks
In addition to the primary clock network and edge clocks the LatticeSC devices also contain a secondary clock network. Built of X6 style routing elements this secondary clock network is ideal for routing slower speed clock and
control signals throughout the device preserving high-speed clock networks for the most timing critical signals.
Edge Clocks
LatticeSC devices have a number of high-speed edge clocks that are intended for use with the PIOs in the implementation of high-speed interfaces. There are eight edge clocks per bank for the top and bottom of the device. The
left and right sides have eight edge clocks per side for both banks located on that side. Figure 2-7 shows the
arrangement of edge clocks.
Edge clock resources can be driven from a variety of sources. Edge clock resources can be driven from:
• Edge clock PIOs in the same bank
• Primary clock PIOs in the same bank
• Routing
• Adjacent PLLs and DLLs
• ELSR output from the clock divider

Precision Clock Divider
Each set of edge clocks has four high-speed dividers associated with it. These are intended for generating a slower
speed system clock from the high-speed edge clock. The block operates in a X2 or X4 mode and maintains a
known phase relationship between the divided down clock and high-speed clock based on the release of its reset
signal. The clock dividers can be fed from selected PIOs, PLLs and routing. The clock divider outputs serve as primary clock sources. This circuit also generates an edge local set/reset (ELSR) signal which is fed to the PIOs via
the edge clock network and is used for the rest of the I/O gearing logic.

Dynamic Clock Select (DCS)
The DCS is a global clock buffer with smart multiplexer functions. It takes two independent input clock sources and
outputs a clock signal without any glitches or runt pulses. This is achieved irrespective of where the select signal is

DCS Block diagram.

Figure 2-10 shows timing waveforms for one of the DCS operating modes. The DCS block can be programmed to
other modes. For more information on the DCS, please see details of additional technical documentation at the end
of this data sheet.
Figure 2-10. DCS Waveforms
Clock Boosting
There are programmable delays available in the clock signal paths in the PFU, PIC and EBR blocks. These allow
setup and clock-to-output times to be traded to meet critical timing without slowing the system clock. If this feature
is enabled then the design tool automatically uses these delays to improve timing performance.
sysCLOCK Phase Locked Loops (PLLs)
The sysCLOCK PLLs provide the ability to synthesize clock frequencies. Each PLL has four dividers associated
with it: input clock divider, feedback divider and two clock output dividers. The input divider is used to divide the
input clock signal, while the feedback divider is used to multiply the input clock signal.
The setup and hold times of the device can be improved by programming a delay in the feedback or input path of
the PLL which will advance or delay the output clock with reference to the input clock. This delay can be either programmed during configuration or can be adjusted dynamically.
The Phase Select block can modify the phase of the clock signal if desired. The Spread Spectrum block supports
the modulation of the PLL output frequency. This reduces the peak energy in the fundamental and its harmonics
providing for lower EMI (Electro Magnetic Interference).
The sysCLOCK PLL can be configured at power-up and then, if desired, reconfigured dynamically through the
serial memory interface bus which connects with the on-chip system bus. For example, the user can select inputs,
loop filters, divider setting, delay settings and phase shift settings. The user can also directly access the SMI bus
through the routing.
The PLL clock input, from pin or routing, feeds into an input divider. There are four sources of feedback signal to the
feedback divider: from the clock net, directly from the voltage controlled oscillator (VCO) output, from the routing or

from an external pin. The signal from the input clock divider and the feedback divider are passed through the programmable delay before entering the phase frequency detector (PFD) unit. The output of this PFD is used to control the voltage controlled oscillator. There is a PLL_LOCK signal to indicate that VCO has locked on to the input
clock signal. Figure 2-11 shows the sysCLOCK PLL diagram.
Figure 2-11. PLL Diagram
For more information on the PLL, please see details of additional technical documentation at the end of this data
sheet.
Digital Locked Loop (DLLs)
In addition to PLLs, the LatticeSC devices have up to 12 DLLs per device. DLLs assist in the management of clocks
and strobes. DLLs are well suited to applications where the clock may be stopped or transferring jitter from input to
output is important, for example forward clocked interfaces. PLLs are good for applications requiring the lowest output jitter or jitter filtering. All DLL outputs are routed as primary/edge clock sources.
The DLL has two independent clock outputs, CLKOP and CLKOS. These outputs can individually select one of the
outputs from the tapped delay line. The CLKOS has optional fine phase shift and divider blocks to allow this output
to be further modified, if required. The fine phase shift block allows the CLKOS output to phase shifted a further 45,
22.5 or 11.25 degrees relative to its normal position. LOCK output signal is asserted when the DLL is locked. The
ALU HOLD signal setting allows users to freeze the DLL at its current delay setting.
There is a Digital Control (DCNTL) bus available from the DLL block. This Digital Control bus is available to the
delay lines in the PIC blocks in the adjacent banks. The UDDCNTL signal allows the user to latch the current value
on the digital control bus.
Figure 2-12 shows the DLL block diagram of the DLL inputs and outputs. The output of the phase frequency detector controls an arithmetic logic unit (ALU) to add or subract one delay tap. The digital output of this ALU is used to
control the delay value of the delay chain and this digital code is transmitted via the DCNTL bus.
The sysCLOCK DLL can be configured at power-up, then, if desired, reconfigured dynamically through the Serial
Memory Interface bus which interfaces with the on-chip Microprocessor Interface (MPI) bus. In addition, users can
drive the SMI interface from routing if desired.
The user can configure the DLL for many common functions such as clock injection match and single delay cell.
Lattice provides primitives in its design for time reference delay (DDR memory) and clock injection delay removal.

PLL/DLL Cascading
The LatticeSC devices have been designed to allow certain combinations of PLL and DLL cascading. The allowable combinations are as follows:
• PLL to PLL Supported
• PLL to DLL Supported
• DLL to DLL Supported
• DLL to PLL Not supported
DLLs are used to shift the clock in relation to the data for source synchronous inputs. PLLs are used for frequency
synthesis and clock generation for source synchronous interfaces. Cascading PLL and DLL blocks allows applications to utilize the unique benefits of both DLL and PLLs.
For further information on the DLL, please see details of additional technical documentation at the end of this data
sheet.
sysMEM Memory Block
The sysMEM block can implement single port, true dual port, pseudo dual port or FIFO memories. Dedicated FIFO
support logic allows the LatticeSC devices to efficiently implement FIFOs without consuming LUTs or routing
resources for flag generation. Each block can be used in a variety of depths and widths as shown in Table 2-5.

Table 2-5. sysMEM Block Configurations
Bus Size Matching
All of the multi-port memory modes support different widths on each of the ports. The RAM bits are mapped LSB
word 0 to MSB word 0, LSB word 1 to MSB word 1 and so on. Although the word size and number of words for
each port varies, this mapping scheme applies to each port.
RAM Initialization and ROM Operation
If desired, the contents of the RAM can be pre-loaded during device configuration. By preloading the RAM block
during the chip configuration cycle and disabling the write controls, the sysMEM block can also be utilized as a
ROM.
Single, Dual and Pseudo-Dual Port Modes
In all the sysMEM RAM modes the input data and address for the ports are registered at the input of the memory
array. The output data of the memory is optionally registered at the output. A clock is required even in asynchronous read mode.
The EBR memory supports three forms of write behavior for dual port operation:
1. Normal — data on the output appears only during a read cycle. During a write cycle, the data (at the current
address) does not appear on the output.
2. Write Through — a copy of the input data appears at the output of the same port.
3. Read-Before-Write — when new data is being written, the old content of the address appears at the output.
FIFO Configuration
The FIFO has a write port with Data-in, WCE, WE and WCLK signals. There is a separate read port with Data-out,
RCE, RE and RCLK signals. The FIFO internally generates Almost Full, Full, Almost Empty, and Empty Flags. The
Full and Almost Full flags are registered with WCLK. The Empty and Almost Empty flags are registered with RCLK.
The range of program values for these flags are in Table 2-6.

Table 2-6. Programmable FIFO Flag Ranges
The FIFO state machine supports two types of reset signals. The first reset signal is a global reset that clears the
contents of the FIFO by resetting the read/write pointer and puts the FIFO flags in initial reset state. The second
reset signal is used to reset the read pointer. The purpose of this reset is to retransmit the data that is in the FIFO.
Programmable I/O Cells (PIC)
Each PIC contains four PIOs connected to their respective PURESPEED I/O Buffer which are then connected to
the PADs as shown in Figure 2-13. The PIO Block supplies the output data (DO) and the Tri-state control signal
(TO) to PURESPEED I/O buffer, and receives input (DI) from the buffer. The PIO contains advanced capabilities to
allow the support of speeds up to 2Gbps. These include dedicated shift and DDR logic and adaptive input logic.
The dedicated resources simplify the design of robust interfaces.

PIOs.
Figure 2-14. Differential Drivers and Receivers
PIO
The PIO contains five blocks: an input register block, output register block, tristate register block, update block, and
a control logic block. These blocks contain registers for both single data rate (SDR), double data rate (DDR), and
shift register operation along with the necessary clock and selection logic.
Input Register Block
The input register block contains delay elements and registers that can be used to condition signals before they are
passed to the device core. Figure 2-16 show the diagram of the input register block. The signal from the PURESPEED I/O buffer (DI) enters the input register block and can be used for three purposes, as a source for the combinatorial (INDD) and clock outputs (INCK), the input into the SDR register/latch block and the input to the delay
block. The output of the delay block can be used as combinatorial (INDD) and clock (INCK) outputs, an input to the
DDR/Shift Register Block or an input into the SDR register block.
Input SDR Register/Latch Block
The SDR register/latch block has a latch and a register/latch that can be used in a variety of combinations to provide a registered or latched output (INFF). The latch operates off high-speed input clocks and latches data on the
positive going edge. The register/latch operates off the low-speed input clock and registers/latches data on the positive going edge. Both the latch and the register/latch have a clock enable input that is driven by the input clock
enable. In addition both have a variety of programmable options for set/reset including, set or reset, asynchronous
or synchronous Local Set Reset LSR (LSR has precedence over CE) and Global Set Reset GSR enable or disable.
The register and latch LSR inputs are driven from LSRI, which is generated from the PIO control MUX. The GSR
inputs are driven from the GSR output of the PIO control MUX, which allows the global set-reset to be disabled on
a PIO basis.
Input Delay Block
The delay block uses 144 tapped delay lines to obtain coarse and fine delay resolution. These delays can be
adjusted during configuration or automatically via DLL or AIL blocks. The Adaptive Input Logic (AIL) uses this delay
block to adjust automatically the delay in the data path to ensure that it has sufficient setup and hold time.
The delay line in this block matches the delay line that is used in the 12 on-chip DLLs. The delay line can be set via
configuration bits or driven from a calibration bus that allows the setting to be controlled either from one of the onchip DLLs or user logic. Controlling the delay from one of the on-chip DLLs allow the delay to be calibrated to the
DLL clock and hence compensated for the variations in process, voltage and temperature.

Lattice Semiconductor LatticeSC Family Data Sheet
Adaptive Input Logic (AIL) Block
The AIL block is available in the A or C pads of each PIO on the left, right and bottom of the chip. This logic automatically adjusts the delay in the data path on a signal-by-signal basis to ensure that it has sufficient set-up and
hold. This capability simplifies the system level design of high-speed interfaces and ultimately allows higher overall
speeds to be achieved.
The AIL block receives data from nine taps in the delay line present in the input delay block. These signals are fed
to 18 registers. The registers operate off the high-speed input clock (9 on the positive edge and 9 on the negative
edge.) The output of these registers, along with the high speed input clock and RUNAIL signal are inputs to the AIL
control logic. If RUNAIL is enabled then the AIL control logic will determine if the delay needs to be adjusted in
order to avoid data transitions within a user specified margin. The margin can be a specified as 2, 4, 6 or 8 delay
increments. The LOCK output indicates that transitions are not occurring within the specified margin of the clock
edge. The AIL logic is automatically configured by the Lattice design tools dependent on the primitives that are
specified. Figure 2-15 shows the arrangement of the adaptive input logic.
Figure 2-15. Adaptive Input Logic and Delay Block
Input DDR/Shift Block
The DDR/Shift block contains registers and associated logic that support DDR and shift register functions using the
high-speed clock and the associated transfer to the low-speed clock domain. It functions as a gearbox allowing
high-speed incoming data to be passed into the FPGA fabric. Each PIO supports DDR and x2 shift functions. If
desired PIOs A and B or C and D can be combined to form x4 shift functions. The PIOs A and C on the left, right
and bottom of the device also contain an optional Adaptive Input Logic (AIL) element. This logic automatically
aligns incoming data with the clock allowing for easy design of high-speed interfaces. Figure 2-16 shows a simpliDelay tap n+16

The output register block provides the ability to register signals from the core of the device before they are passed

the SDR register or the DDR/shift register block. Figure 2-18 shows the diagram of the Output Register Block.
Output SDR Register/Latch Block
The SDR register operates on the positive edge of the high-speed clock. It has clock enable that is driven by the
clock enable output signal generated by the control MUX. In addition it has a variety of programmable options for
set/reset including, set or reset, asynchronous or synchronous Local Set Reset LSR (LSR has precedence over
CE) and Global Set Reset GSR enable or disable. The register LSR input is driven from LSRO, which is generated
from the PIO control MUX. The GSR inputs is driven from the GSR output of the PIO control MUX, which allows the
global set-reset to be disabled on a PIO basis.

The DDR/Shift block contains registers and associated logic that support DDR and shift register functions using the
high-speed clock and the associated transfer from the low-speed clock domain. It functions as a gearbox allowing
low-speed parallel data from the FPGA fabric be output as a higher speed serial stream. Each PIO supports DDR

Tristate Register Block
The tristate register block provides the ability to register tri-state control signals from the core of the device before
they are passed to the PURESPEED I/O buffers. The block contains a register for SDR operation and a group of
three registers for DDR and shift register operation. The output signal tri-state control signal (TO) can be derived
directly from one of the inputs (bypass mode), the SDR shift register, the DDR registers or the data associated with
the buffer (for open drain emulation). Figure 2-20 shows the diagram of the Tristate Register Block.
Tristate SDR Register/Latch Block
The SDR register operates on the positive edge of the high-speed clock. In it has a variety of programmable
options for set/reset including, set or reset, asynchronous or synchronous Local Set Reset LSR and Global Set
Reset GSR enable or disable. The register LSR input is driven from LSRO, which is generated from the PIO control
MUX. The GSR input is driven from the GSR output of the PIO control MUX, which allows the global set-reset to be
disabled on a PIO basis.
Tristate DDR/Shift Register Block
The DDR/Shift block is shared with the output block allowing DDR support using the high-speed clock and the
associated transfer from the low-speed clock domain. It functions as a gearbox allowing low–speed parallel data
from the FPGA fabric to provide a high-speed tri-state control stream.
There is a special mode for DDR-II memory interfaces where the termination is controlled by the output tristate signal. During WRITE cycle when the FPGA is driving the lines, the parallel terminations are turned off. During READ
cycle when the FPGA is receiving data, the parallel terminations are turned on.
Figure 2-20. Tristate Register Block1
Control Logic Block
The control logic block allows the modification of control signals selected by the routing before they are used in the
PIO. It can optionally invert all signals passing through it except the Global Set/Reset. Global Set/Reset can be
enabled or disabled. It can route either the edge clock or the clock to the high-speed clock nets. The clock provided
to the PIO by routing is used as the slow-speed clocks. In addition this block contains delays that can be inserted in
the clock nets to enable Lattice’s unique cycle boosting capability.
Update Block
The update block is used to generate the POS update and NEG update signals used by the DDR/Shift register
blocks within the PIO. Note the update block is only required in shift modes. This is required in order to do the high
speed to low speed handoff. One of these update signals is also selected and output from the PIC as the signal
UPDATE. It consists of a shift chain that operates off either the high-speed input or output clock. The values of each

register in the chain are set or reset depending on the desired mode of operation. The set/reset signal is generated
from either the edge reset ELSR or the local reset LSR. These signals are optionally inverted by the Control Logic
Block and provided to the update block as ELSRUP and LSRUP. The Lattice design tools automatically configure
and connect the update block when one of the DDR or shift register primitives is used.
Figure 2-21. Update Block
PURESPEED I/O Buffer
Each I/O is associated with a flexible buffer referred to as PURESPEED I/O buffer. These buffers are arranged
around the periphery of the device in seven groups referred to as Banks. The PURESPEED I/O buffers allow users
to implement the wide variety of standards that are found in today’s systems including LVCMOS, SSTL, HSTL,
LVDS and LVPECL. The availability of programmable on-chip termination for both input and output use, further
enhances the utility of these buffers.
PURESPEED I/O Buffer Banks
LatticeSC devices have seven PURESPEED I/O buffer banks; each is capable of supporting multiple I/O standards. Each PURESPEED I/O bank has its own I/O supply voltage (VCCIO), and two voltage references VREF1 and
V
REF2 resources allowing each bank to be completely independent from each other. Figure 2-22 shows the seven
banks and their associated supplies. Table 2-7 lists the maximum number of I/Os per bank for the whole LatticeSC
family.
In the LatticeSC devices, single-ended output buffers and ratioed input buffers (LVTTL, LVCMOS, PCI33 and PCIX33)
are powered using VCCIO. In addition to the bank VCCIO supplies, the LatticeSC devices have a VCC core logic power
supply, and a VCCAUX supply that power all differential and referenced buffers. VCCAUX also powers a predriver of
single-ended output buffers to enhance buffer performance.
Each bank can support up to two separate VREF voltages, VREF1 and VREF2 that set the threshold for the referenced input buffers. In the LatticeSC devices any I/O pin in a bank can be configured to be a dedicated reference
voltage supply pin. Each I/O is individually configurable based on the bank’s supply and reference voltages.
Differential drivers have user selectable internal or external bias. External bias is brought in by the VREF1 pin in the
bank. External bias for differential buffers is needed for applications that requires tighter than standard output common mode range.
Since a bank can have only one external bias circuit for differential drivers, LVDS and RSDS differential outputs can
be mixed in a bank but not with HYPT (HyperTransport).
If a differential driver is configured in a bank, one pin in that bank becomes a DIFFR pin. This DIFFR pin must be
connected to ground via an external 1K +/-1% ohm resistor.

In addition, there are dedicated Terminating Supply (VTT) pins to be used as terminating voltage for one of the two
ways to perform parallel terminations. These VTT pins are available in banks 2-7, these pins are not available in
some packages. When these pins are not used they should be left unconnected. There are further restrictions on
the use of VTT pins, for additional details refer to technical information at the end of this data sheet.

PCI Clamp
A programmable PCI clamp is available on the top and bottom banks of the device. The PCI clamp can be turned
“ON” or “OFF” on each pin independently. The PCI clamp is used when implementing a 3.3V PCI interface. The PCI
Specification, Revision 2.2 requires the use of clamping diodes for 3.3V operation. For more information on the PCI
interface, please refer to the PCI Specification, Revision 2.2.
Programmable Slew Rate Control
All output and bidirectional buffers have an optional programmable output slew rate control that can be configured
for either low noise or high-speed performance. Each I/O pin has an individual slew rate control. This allows
designers to specify slew rate control on a pin-by-pin basis. This slew rate control affects both the rising and falling
edges.
Programmable Termination
Many of the I/O standards supported by the LatticeSC devices require termination at the transmitter, receiver or both.
The SC devices provide the capability to implement many kinds of termination on-chip, minimizing stub lengths and
hence improving performance. Utilizing this feature also has the benefit of reducing the number of discrete components required on the circuit board. The termination schemes can be split into two categories single-ended and differential.
Single Ended Termination
Single Ended Outputs: The SC devices support a number of different terminations for single ended outputs:
• Series
• Parallel to VCCIO or GND
• Parallel to VCCIO/2
• Parallel to VCCIO/2 combined with series
Figure 2-23 shows the single ended output schemes that are supported. The nominal values of the termination resistors are shown in Table 2-10.2-28

Single Ended Inputs: The SC devices support a number of different termination schemes for single ended inputs:
• Parallel to VCCIO or GND
• Parallel to VCCIO/2
• Parallel to VTT
Figure 2-24 shows the single ended input schemes that are supported. The nominal values of the termination resistors are shown in Table 2-9.
Figure 2-24. Input Termination Schemes
In many situations designers can chose whether to use Thevenin or parallel to VTT termination. The Thevenin
approach has the benefit of not requiring a termination voltage to be applied to the device. The parallel to VTT
approach consumes less power.
VTT Termination Resources
Each I/O bank, except bank 1, has a number of VTT pins that must be connected if VTT is used. Note VTT pins can
sink or source current and the power supply they are connected to must be able to handle the relatively high currents
associated with the termination circuits. Note: VTT is not available in all package styles.
On-chip parallel termination to VTT is supported at the receiving end only. On-chip parallel output termination to VTT is
not supported.
The VTT internal bus is also connected to the internal VCMT node. Thus in one bank designers can implement either
VTT termination or VCMT termination for differential inputs.
DDRII/RLDRAMII Termination Support
The DDR II memory and RLDRAMII (in Bidirection Data mode) standards require that the on-chip termination to VTT
be turned on when a pin is an input and off when the pin is an output. The LatticeSC devices contain the required circuitry to support this behavior. For additional detail refer to technical information at the end of the data sheet.

Differential Input Termination
The LatticeSC device allows two types of differential termination. The first is a single resistor across the differential
inputs. The second is a center-tapped system where each input is terminated to the on-chip termination bus VCMT.
The VCMT bus is DC-coupled through an internal capacitor to ground.
Figure 2-25 shows the differential termination schemes and Table 2-9 shows the nominal values of the termination
resistors.
Figure 2-25. Differential Termination Scheme
Calibration
There are two calibration sources that are associated with the termination scheme used in the LatticeSC devices:
• DIFFR – This pin occurs in each bank and must be connected through a 1K+/-1% resistor to ground if differential outputs are used.
• XRES – There is one of these pins per device. It is used for several functions including calibrating on-chip
termination. This pin should always be connected through a 1K+/-1% resistor to ground.
The LatticeSC devices support two modes of calibration:
• Continuous – In this mode the SC devices continually calibrate the termination resistances. Calibration happens several times a second. Using this mode ensures that termination resistances remain calibrated as
the silicon junction temperature changes.
• User Request – In this mode the calibration circuit operates continuously. However, the termination resistor
values are only updated on the assertion of the calibration_update signal available to the core logic.
For more information on calibration, refer to the details of additional technical documentation at the end of this data
sheet.
Hot Socketing
The LatticeSC devices have been carefully designed to ensure predictable behavior during power-up and powerdown. To ensure proper power sequencing, care must be taken during power-up and power-down as described
below. During power-up and power-down sequences, the I/Os remain in tristate until the power supply voltage is
high enough to ensure reliable operation. In addition, leakage into I/O pins is controlled to within specified limits,

this allows for easy integration with the rest of the system. These capabilities make the LatticeSC ideal for many
multiple power supply and hot-swap applications.
Power-Up Requirements
To prevent high power supply and input pin currents, each VCC, VCC12, VCCAUX, VCCIO and VCCJ power supplies must have a monotonic ramp up time of 75 ms or less to reach its minimum operating voltage. Apart from VCC
and VCC12, which have an additional requirement, and VCCIO and VCCAUX, which also have an additional
requirement, the VCC, VCC12, VCCAUX, VCCIO and VCCJ power supplies can ramp up in any order, with no
restriction on the time between them. However, the ramp time for each must be 75 ms or less. Configuration of the
device will not proceed until the last power supply has reached its minimum operating voltage.
Additional Requirement for VCC and VCC12
VCC12 must always be higher than VCC. This condition must be maintained at ALL times, including during powerup and power-down. Note that for 1.2V only operation, it is advisable to source both of these supplies from the
same power supply.
Additional Requirement for VCCIO and VCCAUX
If any VCCIOs are 1.2/1.5/1.8V, then VCCAUX MUST be applied before them. If any VCCIO is 1.2/1.5/1.8V and is
powered up before VCCAUX, then when VCCAUX is powered up, it may drag VCCIO up with it as it crosses
through the VCCIO value. (Note: If the VCCIO supply is capable of sinking current, as well as the more usual sourcing capability, this behavior is eliminated. However, the amount of current that the supply needs to sink is unknown
and is likely to be in the hundreds of milliamps range).
Power-Down Requirements
To prevent high power supply and input pin currents, power must be removed monotonically from either VCC or
VCCAUX (and must reach the power-down trip point of 0.5V for VCC, 0.95V for VCCAUX) before power is removed
monotonically from VCC12, any of the VCCIOs, or VCCJ. Note that VCC12 can be removed at the same time as
VCC, but it cannot be removed earlier. In many applications, VCC and VCC12 will be sourced from the same power
supply and so will be removed together. For systems where disturbance of the user pins is a don't care condition,
the power supplies can be removed in any order as long as they power down monotonically within 200ms of each
other.
Additionally, if any banks have VCCIO=3.3V nominal (potentially banks 1, 4, 5) then VCCIO for those banks must
not be lower than VCCAUX during power-down. The normal variation in ramp-up times of power supplies and voltage regulators is not a concern here.
Note: The SERDES power supplies are NOT included in these requirements and have no specific sequencing
requirements. However, when using the SERDES with VDDIB or VDDOB that is greater than 1.2V (1.5V nominal
for example), the SERDES should not be left in a steady state condition with the 1.5V power applied and the 1.2V
power not applied. Both the 1.2V and 1.5V power should be applied to the SERDES at nominally the same time.
The normal variation in the ramp-up times of power supplies and voltage regulators is not a concern here.
Supported Source Synchronous Interfaces
The LatticeSC devices contain a variety of hardware, such as delay elements, DDR registers and PLLs, to simplify
the implementation of Source Synchronous interfaces. Table 2-11 lists Source Synchronous and DDR/QDR standards supported in the LatticeSC. For additional detail refer to technical information at the end of the data sheet.2-32

flexiPCS Functionality
The LatticeSC family combines a high-performance FPGA fabric, high-performance I/Os and large embedded
RAM in a single industry leading architecture. LatticeSC devices also feature up to 32 channels of embedded SERDES with associated Physical Coding Sublayer (PCS) logic. The flexiPCS logic can be configured to support
numerous industry standard high-speed data transfer protocols.
Each channel of flexiPCS logic contains dedicated transmit and receive SERDES for high-speed, full-duplex serial
data transfers at data rates up to 3.4 Gbps. The PCS logic in each channel can be configured to support an array of
popular data protocols including SONET (STS-12/STS-12c, STS-48/STS-48c, and TFI-5 support of 10 Gbps or
above), Gigabit Ethernet (compliant to the IEEE 1000BASE-X specification), 1.02 or 2.04 Gbps Fibre Channel,
PCI-Express, and Serial RapidIO. In addition, the protocol based logic can be fully or partially bypassed in a number of configurations to allow users flexibility in designing their own high-speed data interface.
Protocols requiring data rates above 3.4 Gbps can be accommodated by dedicating either one pair or all four channels in one flexiPCS quad block to one data link. One quad can support full-duplex serial data transfers at data
rates up to 13.6 Gbps. A single flexiPCS quad can be configured to support 10Gb Ethernet (with a fully compliant
XAUI interface), 10Gb Fibre Channel, and x4 PCI-Express and 4x RapidIO.
The flexiPCS also provides bypass modes that allow a direct 8-bit or 10-bit interface from the SERDES to the
FPGA logic which can also be geared to run at 1/2 speed for a 16-bit or 20-bit interface to the FPGA logic. Each
SERDES pin can be DC coupled independently and can allow for both high-speed and low-speed operation down
to DC rates on the same SERDES pin, as required by some Serial Digital Video applications.
The ispLEVER design tools from Lattice support all modes of the flexiPCS. Most modes are dedicated to applications associated with a specific industry standard data protocol. Other more general purpose modes allow a user to
define their own operation. With ispLEVER, the user can define the mode for each quad in a design. Nine modes
are currently supported by the ispLEVER design flow:
• 8-bit SERDES Only
• 10-bit SERDES Only
• SONET (STS-12/STS-48)
• Gigabit Ethernet
• Fibre Channel
• XAUI

flexiPCS Quad
The flexiPCS logic is arranged in quads containing logic for four independent full-duplex data channels. Each
device in the LatticeSC family has up to eight quads of flexiPCS logic. The LatticeSC Family Selection Guide table
on the first page of this data sheet contains the number of flexiPCS channels present on the chip. Note that in
some packages (particularly lower pin count packages), not all channels from all quads on a given device may be
bonded to package pins.
Each quad supports up to four channels of full-duplex data and can be programmed into any one of several protocol based modes. Each quad requires its own reference clock which can be sourced externally or from the FPGA
logic. The user can utilize between one and four channels in a quad, depending on the application.
Figure 2-26 shows an example of four flexiPCS quads in a LatticeSC device. Quads are labeled according to the
address of their software controlled registers.
Figure 2-26. LatticeSC flexiPCS
Since each quad has its own reference clock, different quads can support different standards on the same chip.
This feature makes the LatticeSC family of devices ideal for bridging between different standards.
flexiPCS quads are not dedicated solely to industry standard protocols. Each quad (and each channel within a
quad) can be programmed for many user defined data manipulation modes. For example, modes governing userdefined word alignment and multi-channel alignment can be programmed for non-standard protocol applications.
For more information on the functions and use of the flexiPCS, refer to the LatticeSC flexiPCS Data Sheet.

System Bus
Each LatticeSC device connects the FPGA elements with a standardized bus framework referred to as a System
Bus. Multiple bus masters optimize system performance by sharing resources between different bus masters such
as the MPI and configuration logic. The wide data bus configuration of 32 bits with 4-bit parity supports high-bandwidth, data intensive applications.
There are two types of interfaces on the System Bus, master and slave. A master interface has the ability to perform actions on the bus, such as writes and reads to and from a specific address. A slave interface responds to the
actions of a master by accepting data and address on a write and providing data on a read. The System Bus has a
memory map which describes each of the slave peripherals that is connected on the bus. Using the addresses
listed in the memory map, a master interface can access each of the slave peripherals on the System Bus. Any and
all peripherals on the System Bus can be used at the same time. Table 2-12 list all of the available user peripherals
on the System Bus after device power-up.
Table 2-12. System Bus User Peripherals
The peripherals listed in Table 2-12 can be added when the System Bus module is created using Module IP/Manager (ispLEVER Module/IP Manager).
Figure 2-27 also lists the existing peripherals on the System Bus. The gray boxes are available only during configuration. Refer to Lattice technical note TN1080, LatticeSC sysCONFIG Usage Guide, for configuration options. The
Status and Config box refers to internal System Bus registers. This document presents all the interfaces listed in
Table 2-12 in detail to help the user utilize the desired functions of the System Bus.
Figure 2-27. LatticeSC System Bus Interfaces
Several interfaces exist between the System Bus and other FPGA elements. The MPI interface acts as a bridge
between the external microprocessor bus and System Bus. The MPI may work in an independent clock domain
from the System Bus if the System Bus clock is not sourced from the external microprocessor clock. Pipelined

operation allows high-speed memory interface to the EBR and peripheral access without the requirement for additional cycles on the bus. Burst transfers allow optimal use of the memory interface by giving advance information of
the nature of the transfers.
Details for the majority of the peripherals can be found in the associated technical documentation, see details at
the end of this data sheet. Additional details of the MPI are provided below.
Microprocessor Interface (MPI)
The LatticeSC family devices have a dedicated synchronous MPI function block. The MPI is programmable to operate with PowerPC/PowerQUICC MPC860/MPC8260 series microprocessors. The MPI implements an 8-, 16-, or
32-bit interface with 1-bit, 2-bit, or 4-bit parity to the host processor (PowerPC) that can be used for configuration
and read-back of the FPGA as well as for user-defined data processing and general monitoring of FPGA functions.
The control portion of the MPI is available following power-up of the FPGA if the mode pins specify MPI mode, even
if the FPGA is not yet configured. The width of the data port is selectable among 8-, 16-, or 32-bit and the parity bus
can be 1-, 2-, or 4-bit. In configuration mode the data and parity bus width are related to the state of the M[0:3]
mode pins. For post-configuration use, the MPI must be included in the configuration bit stream by using an MPI
library element in your design from the ispLEVER primitive library, or by setting the bit of the MPI configuration control register prior to the start of configuration. The user can also enable and disable the parity bus through the con-
figuration bit stream. These pads can be used as general I/O when they are not needed for MPI use.
The MPI block also provides the capability to interface directly to the FPGA fabric with a databus after configuration.The bus protocol is still handled by the MPI block but the direct FPGA access allows high-speed block data
transfers such as DMA transactions. Figure 2-28 shows one of the ways a PowerPC is connected to MPI.

Lattice Semiconductor LatticeSC Family Data Sheet
Configuration and Testing
The following section describes the configuration and testing features of the LatticeSC family of devices.
IEEE 1149.1-Compliant Boundary Scan Testability
All LatticeSC devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant test access
port (TAP). This allows functional testing of the circuit board, on which the device is mounted, through a serial scan
path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in
and loaded directly onto test nodes, or test data to be captured and shifted out for verification. The test access port
consists of dedicated I/Os: TDI, TDO, TCK and TMS. The test access port has its own supply voltage VCCJ and can
operate with LVCMOS33, 25 and 18 standards. For additional detail refer to technical information at the end of the
data sheet.
Device Configuration
All LatticeSC devices contain three possible ports that can be used for device configuration. The serial port, which
supports bit-wide configuration, and the sysCONFIG port that supports both byte-wide and serial configuration.
The MPI port supports 8-bit, 16-bit or 32-bit configuration.
The serial port supports both the IEEE Std. 1149.1 Boundary Scan specification and the IEEE Std. 1532 In-System
Configuration specification. The sysCONFIG port is a 20-pin interface with six of the I/Os used as dedicated pins
and the rest being dual-use pins. When sysCONFIG mode is not used, these dual-use pins are available for general purpose I/O. All I/Os for the sysCONFIG and MPI ports are in I/O bank #1.
On power-up, the FPGA SRAM is ready to be configured with the sysCONFIG port active. The IEEE 1149.1 serial
mode can be activated any time after power-up by sending the appropriate command through the TAP port. Once a
configuration port is selected, that port is locked and another configuration port cannot be activated until the next
re-initialization sequence. For additional detail refer to technical information at the end of the data sheet.
Internal Logic Analyzer Capability (ispTRACY)
All LatticeSC devices support an internal logic analyzer diagnostic feature. The diagnostic features provide capabilities similar to an external logic analyzer, such as programmable event and trigger condition and deep trace memory. This feature is enabled by Lattice’s ispTRACY. The ispTRACY utility is added into the user design at compile
time. For additional detail refer to technical information at the end of the data sheet.
Temperature Sensing
Lattice provides a way to monitor the die temperature by using a temperature-sensing diode that is designed into
every LatticeSC device. The difference in VBE of the diode at two different forward currents varies with temperature.
This relationship is shown in Figure 2-29.
This temperature-sensing diode is designed to work with an external temperature sensor such as the Maxim
1617A. The Maxim 1617A is configured to measure difference in VBE (of the temperature-sensing diode) at 10µA
and at 100µA. This difference in VBE voltage varies with temperature at approximately 1.64 mV/°C. A typical device
with a 85°C junction temperature will measure approximately 593mV. For additional detail refer to technical information at the end of the data sheet.2-37
Architecture
Lattice Semiconductor LatticeSC Family Data Sheet
Figure 2-29. Sensing Diode Typical Characteristics
Oscillator
Every LatticeSC device has an internal CMOS oscillator, which is used as a master serial clock for configuration
and is also available as a potential general purpose clock (MCK) for the FPGA core. There is a K divider (divide by
2/4/8/16/32/64/128) available with this oscillator to get lower MCK frequencies. This clock is available as a general
purpose clock signal to the software routing tool. For additional detail refer to technical information at the end of the
data sheet.
Density Shifting
The LatticeSC family has been designed to ensure that different density devices in the same package have the
same pin-out. Furthermore, the architecture ensures a high success rate when performing design migration from
lower density parts to higher density parts. In many cases, it is also possible to shift a lower utilization design targeted for a high-density device to a lower density device. However, the exact details of the final resource utilization
will impact the likely success in each case.

Signal Name I/O Description4-3
Pinout Information
Lattice Semiconductor LatticeSC Family Data Sheet
DOUT O
Serial data output that can drive the D0/DIN of daisy-chained slave
devices. The data-stream from this output will propagate preamble bits
of the bitstream to daisy-chained devices. Data out on DOUT changes
on the rising edge of CCLK.
QOUT/CEON O
During daisy-chaining configuration, QOUT is the serial data output
that can drive the D0/DIN of daisy-chained slave devices that do not
propagate preamble bits. Data out on QOUT changes on the rising
edge of CCLK.
During parallel-chaining configuration, active low CEON enables the
cascaded slave device to receive bitstream data.
RDN I
Used in the asynchronous peripheral configuration mode. A low on
RDN changes D[7:3] into status outputs. WRN and RDN should not be
used simultaneously. If they are, the write strobe overrides.
WRN I When the FPGA is selected, a low on the write strobe, WRN, loads the
data on D[7:0] inputs into an internal data buffer.
CS0N CS1 I
Used in the asynchronous peripheral, slave parallel and MPI modes.
The FPGA is selected when CS0N is low and CS1 is high. During con-
figuration, a pull-up is enabled on both except with MPI DMA access
control.
A[21:0] I/O
In master parallel mode, A[21:0] is an output and will address the con-
figuration EPROMs up to 4 MB space. For MPI configuration mode,
A[17:0] will be the MPI address MPI_ADDR[31:14], A[19:18] will be
the transfer size and A[21:20] will be the burst mode and burst in process.
D[n:0] I/O
In parallel configuration modes, D[7:0] receives configuration data,
and each pin is pull-up enabled. For slave serial mode, D0 is the data
input.
D[7:3] is the output internal status for peripheral mode when RDN is
low.
D[7:0] is also the first byte of MPI data pins.
In MPI configuration mode, MPI selectable data bus width from 8 and
16-bit. Driven by a bus master in a write transaction. Driven by MPI in
a read transaction.
DP[m:0] I/O MPI selectable parity data bus width from 1, 2, and 3-bit DP[0] for
D[7:0], DP[1] for D[15:8], and DP[2] for D[23:16].
BUSYN/RCLK O
During configuration in peripheral mode, high on BUSYN/RCLK indicates another byte can be written to the FPGA. If a read operation is
done when the device is selected, the same status is also available on
D[7] in asynchronous peripheral mode.
During configuration in slave parallel mode, low on BUSYN/RCLK
inhibits the external host from sending new data.
During configuration in master parallel and master byte modes,
BUSYN/RCLK is a read clock output signal to an external memory.
The BUSYN/RCLK frequency is the same as CCLK when used with
uncompressed bitstreams. BUSYN/RCLK will be 1/8 the frequency of
CCLK when the bitstream is compressed.
During configuration in SPI mode, BUSYN/RCLK is generated by the
device and connected to the CLK input of the FLASH memory.

MPI_IRQ_N O
MPI Interrupt request active low signal is controlled by system bus
interrupt controller and may be sourced from any bus error or MPI con-
figuration error. It can be connected to one of MPC860 IRQ pins.
MPI Interface (User I/O if MPI is not used.)
MPI_CS0N MPI_CS1 I
MPI chip select pins, active low on MPI_CS0N while active high on
MPI_CS1. Both have to be active during the whole transfer data
phase. During transfer address phase, both can be inactive so that the
decoding for them from address can be slow. If they are active during
address phase, one cycle can be saved for sync read.
MPI_CLK I
This is the PowerPC bus clock. It can be a source of the clock for
embedded system bus. If MPI_CLK is used as system bus clock, MPI
will be set into sync mode by default. All of the operation on PowerPC
side of MPI are synchronized to the rising edge of this clock.
MPI_TSIZ[1:0] I Driven by a bus master to indicate the data transfer size for the transaction. 01 for byte, 10 for half-word, and 00 for word.
MPI_WR_N I Driven high indicates that a read access is in progress. Driven low
indicates that a write access is in process.
MPI_BURST I Driven active low indicates that a burst transfer is in progress. Driven
high indicates that the current transfer is not a burst.
MPI_BDIP I
Active low “Burst Data in Process” is driven by a PowerPC processor.
Asserted indicates that the second beat in front of the current one is
requested by the master. Negated before the burst transfer ends to
abort the burst data phase.
MPI_STRBN I Driven active low indicates the start of a transaction on the PowerPC
bus. MPI will strobe the address bus at next rising edge of clock.
MPI_ADDR[31:14] I
Address bus driven by a PowerPC bus master. Only 18-bit width is
needed. It has to be the least significant bit of the PowerPC 32-bit
address A[31:14].
MPI_DAT[n:0] I/O Selectable data bus width from 8, and 16-bit. Driven by a bus master
in a write transaction. Driven by MPI in a read transaction.
MPI_PAR[m:0] I/O
Selectable parity bus width from 1, 2, and 3-bit. MPI_DP[0] for
MPI_D[7:0], MPI_DP[1] for MPI_D[15:8] and MPI_DP[2] for
MPI_D[23:16].
MPI_TA O Transfer acknowledge. Driven active low indicates that MPI received
the data on the write cycle or returned data on the read cycle.
MPI_TEA O Transfer Error Acknowledge. Driven active low indicates that MPI
detects a bus error on the internal system bus for current transaction.
MPI_RETRY O Active low MPI Retry requests the MPC860 to relinquish the bus and
retry the cycle.
Multi-chip Alignment (User I/O if not used.)
MCA_DONE_OUT O Multi-chip alignment done output (to second MCA chip)
MCA_DONE_IN I Multi-chip alignment done input (from second MCA chip)
MCA_CLK_P[1:2]_OUT O Multi-chip alignment clock [1:2] output (sourced by MCA master chip)

Introduction
1.1 Power 2 You
This book provides technical details and design considerations for implementing the common
circuit board power management functions shown as 3-D blocks in Figure 1-1 and Figure 1-2.
This book also provides generalized cost effective solutions for each of these functions that can
be customized to meet a circuit board’s specific voltage, current and control environment.
For readers viewing this document in .pdf format, the 3-D blocks in Figure 1-1 and Figure 1-2
are hyperlinked to the appropriate section of Chapter 2, where multiple circuit options are provided for that particular power management function. Each of the circuit options hyperlink to a
detailed description in the relevant chapters.
If you are already familiar with Lattice Semiconductor Power Manager II devices and need to
find a solution for a power management function:
1. Click on the required power management block in Figure 1-1.
2. You will automatically navigate to the section of Chapter 2 that provides multiple circuit
options for the selected power management function.
3. Click on the relevant circuit option.
4. You will automatically navigate to the detailed description of that circuit diagram.
If you wish to read about the general board power management blocks, the design criteria and
circuit options, read this chapter. After reading this chapter, you can skip Chapter 2 - “Solutions Summary” on page 2-1 and continue with Chapter 3 - “Reset Generators & Supervisors”
on page 3-1.
What is Power Management?
Every circuit board is powered from one or more sources called the input, or primary, power
supplies. And, every circuit board performs one or more functions using a number of ICs, such
as ASICs, CPUs, FPGAs, and so on. These ICs are called the payload ICs. The circuit board
generates multiple power rails from the input supplies to power these payload ICs, using board Power 2 You: A Guide to Power Supply Management and Control
1-2 Introduction
mounted supplies called primary and secondary supplies. The term ‘Power Management’ in this book
includes all power rail control functions implemented in a circuit board. Typically, input power rails are
controlled by power management functions such as hot-swap control and redundant power rail control.
On the payload side, power management functions include sequencing, monitoring, supervisory signal
generation, trimming and margining.
Typical Board Power Supply Architectures
Circuit boards can be broadly classified into two types:
1. Boards that derive input power supply from a backplane with its power always on and the boards
plugged into or extracted from the backplane without turning the power off – these are called hotswappable boards, shown in Figure 1-1.
2. Boards that derive power from an external power supply that is turned on after the board is connected
and is turned off before the board is disconnected – these are called non hot-swappable boards.
There are solutions to implement all of the critical power supply control functions. Advanced power supply designers can click on any of the hyperlinked functions to see the solution. To learn the background of
all these functions, continue reading this chapter.
Figure 1-1. Power Management in a Hot-Swappable Circuit Board. (If viewing this document in .pdf format,
click on any of the 3-D blocks to jump to implementation details.)
Figure 1-1 illustrates the power supply architecture of a circuit board with the common power management blocks shown in 3-D. A hot-swappable board derives its power from one or more supplies from the
backplane. There can be more than one set of supplies sourced from the backplane, so these boards are
operational even when one of the supplies fails. The backplane supplies in Figure 1-1 are also called the
primary supplies.
In systems that require high availability, such as telecom / datacom systems, backplanes provide redundant supplies called on-line and standby power. The Power Supply OR’ing Controller, also called the
redundant power supply controller, selects between the online and standby supplies to derive the
power to the board. (Refer to “2.4 Redundant Supply Management” on page 2-14.)
In order to extract and reinsert the boards from the backplane without disturbing the other boards plugged
into the same backplane, a hot-swap controller function is implemented on each of these circuit boards.

Introduction
(Refer to “2.3 Hot-Swap Controllers” on page 2-6.) In some cases, the supply rail output from the hotswap controller feeds one or more DC-DC converters, shown in Figure 1-1 as ‘DC-DC Primary’ supplies.
Primary supplies are used to derive one or more main payload supply rails, which are also called secondary supply rails and are shown in Figure 1-1 as the ‘DC-DC Secondary’ supplies. These secondary supplies may have to be sequenced either through the DC-DC converter enable signals or through
MOSFETs. Sequencing of these supplies is controlled by the sequence controller. (Refer to “2.2 Power
Supply Sequencing” on page 2-3.) After all supplies are sequenced, the reset generator starts the board’s
normal operation by releasing the reset signal to the CPU. (Refer to “2.1 N-Supply Supervisor, Reset
Generator and Watchdog Timer” on page 2-1.) The voltage and current are monitored for faults and
board shut down or reset generation functions are initiated as a result. (Refer to “2.1 N-Supply Supervisor, Reset Generator and Watchdog Timer” on page 2-1.) In addition, monitoring these lower voltages for
faults should take into consideration, and compensate for, other error sources such as the ground voltage
difference between the supply and the monitoring device. For example, the fault level of 1.2V is 1.2V *
5% = ±60mV. The ground voltage difference between different points in the circuit board can be be as
much as 20mV to 30mV. To compensate for the error, differential sensing, as shown in Figure 3-9 on
page 9, is used.
Modern ICs require lower core voltages (1.2V or lower) with high current capacity (10A or higher) with
reduced voltage tolerance. To meet these stringent supply requirements, a power supply trimming controller is often required. (Refer to “2.6 Trimming and Margining” on page 2-23.)
For quality assurance purposes, four-corner testing of boards (voltage and temperature) frequently
requires margining of supplies. These boards use margining controllers. (Refer to “2.6 Trimming and
Margining” on page 2-23.)
In some applications, such as GSM basestation boards, microwave boards and boards supporting hotpluggable mezzanine cards, it may be necessary to power an external unit, such as a remote radio head or
an outdoor antenna, or supply power to an AMC. To support these functions, the power feed controller
is required. (Refer to “2.5 Power Feed Controllers” on page 2-19.)
Figure 1-2 shows the power management requirements in a non hot-swappable circuit board. These
boards require primary and secondary power management controllers, as shown in Figure 1-2. The only
primary power management function that is not relevant in these non-hot-swappable boards is the hotswap controller. Systems that typically require non-hot-swappable boards include routers in “pizza-box”
form factor, personal computers and medical ultrasound systems.Power 2 You: A Guide to Power Supply Management and Control

Typical Power Management Implementations and Their Drawbacks
The power rails in a board currently are managed by simple, single function integrated circuits (ICs) on
both the primary and secondary sides. On the input side, each function shown in Figure 1-1 requires different ICs, depending on the rail voltage, board power and other control specifications.
Modern circuit boards with complex payload ICs typically require five or more secondary power rails.
Monitoring, sequencing and the generation of resets in these boards require multiple single function ICs.
Together, the power management section requires multiple types of single function power management
ICs in a given system. This results in a larger bill of materials (BOM), higher cost of inventory and
assembly, as well as reduced reliability.
The cost of the power management portion in a circuit board increases with the number of rails, and the
number of power management functions. Lower cost single function power management ICs are usually
less accurate in monitoring for faults, resulting in reduced board reliability.
In order to reduce the number of secondary power management ICs, some designs use microcontrollers
with an Analog-to-Digital (ADC) converter to monitor power supplies and use software to adapt to
board-specific requirements. These microcontrollers are too slow to respond to power supply faults (5 to
10ms) and are unreliable, as they use hundreds of lines of code to perform power management functions
and require a watchdog timer to monitor software flow. Microcontrollers are also used because the
changes to power management can be met simply by changing software, as opposed to modifying the circuit board layout. However, modifications to software are almost always avoided, as most companies
have strict control over software releases.
The ideal power management solution is the one that has the following characteristics:
1. Lower cost and reduced bill of material, and flexibility to meet individual board power management
needs.
2. Increased board reliability through increased supply fault monitoring accuracy.

Board-specific power management is implemented using the PAC-Designer software: an intuitive, userfriendly software tool set. The PAC-Designer software enables the following:
1. Configure voltage monitoring thresholds for a given voltage rail.
2. Configure MOSFET driver characteristics to meet turn on and off ramp rates.

Reset Generators & Supervisors
3.1 Introduction
One of the most important peripheral ICs required for a microprocessor is a reset generator and
a watchdog timer.
The functions of a reset generator are:
1. Hold the processor in a reset condition for an extended period of time during a power turn-on
event.
2. If any supply is faulty, activate the reset to prevent it from mis-executing instructions and/or
risk Flash memory corruption.
The functions of a watchdog timer are:
1. A monitor for software execution using the trigger generated by the software.
2. If the processor skips a trigger, activate an interrupt or reset the CPU to initiate a recovery
process.
Traditional reset generators monitor just one input supply to generate the reset signal. However, most modern processors operate using many supplies, as shown in Figure 3-1. Because a
fault on any of the supplies could result in the processor mis-executing instructions, reset generators that monitor only one supply are not adequate. Instead, reset generators are required
that monitor all the relevant supplies for faults in order to generate the CPU reset. Figure 3-1
illustrates this. In the example shown it is not clear which of the five supplies should be chosen
for reset.Power 2 You: A Guide to Power Supply Management and Control
3-2 Reset Generators & Supervisors
Figure 3-1. Single Rail Reset Generator Cannot Guarantee Reliable Reset Generation
In Figure 3-1, the processor requires 1.2V for its core, 1.8V and 0.9V for communicating with DDRII
memory and 3.3V for communicating with Flash memory and other peripherals. The processor operates
reliably only if all of its supply rails are within the datasheet-specified voltage limits; for example, the
acceptable tolerance for: 3.3V (±5%), 1.8V (±5%), 1.2V (±3%), and 0.9V (±5%). One common behavior
of a microprocessor when operating at a core voltage less than its specified low voltage level is the misinterpretation of instructions. When the instructions are misinterpreted (also called mis-executed), the program execution becomes unpredictable and the program can hang (not perform the intended task).
If the I/O voltage drops below the specified signaling threshold level, the instruction/data transferred
between the memory and the processor can be corrupted.
The misinterpretation of instructions, or proper execution of corrupted instructions, by a microprocessor
results in unpredictable behavior; in some cases, the microprocessor could overwrite the on-board Flash
memory, resulting in a failed circuit board. Imagine the circuit board failing just because it was extracted
from its sub-rack slot!
Unpredictable behavior under low voltage conditions is limited not only to microprocessors, but is also
true for any ASIC / FPGA on the board. For example, if the power supply voltage drops below the limit
for a networking ASIC, it might send a garbled packet. In some cases it might lose an internally buffered
acknowledged packet, resulting in a corrupt message.
Reliable Reset Generation by Monitoring All Supply Rails
To prevent the processor from operating when any of its supplies is faulty, one has to monitor all supplies.
Monitoring all the supplies for faults is known as supply supervision. Supervisor ICs are used to monitor
multiple supplies simultaneously. The following functions are typically performed by one or multiple
supervisor ICs:
1. Accurately monitor multiple supply rails for faults and quickly generate an interrupt
2. If the processor core or memory supplies fail, reset the processor

Figure 3-2. The Most Reliable Reset Generator ICs Monitor All Supplies (Supervisor IC)
Parts of a Supervisor IC
Figure 3-3 shows a simple, single supply, voltage monitoring circuit.
Figure 3-3. Single Power Supply Voltage Monitoring Circuit
This circuit uses a voltage comparator to monitor the supply voltage. One limb of the comparator is held
at a constant reference voltage through the bandgap voltage reference. The monitored power supply voltage is attenuated using a resistor network such that the attenuated voltage is greater than the bandgap reference voltage as long as the supply voltage is above the fault level.
For example, the bandgap voltage is 2V, and the power supply should be monitored for 3.3V - 5%
(= 3.135V). The attenuator is selected such that the output of the attenuator is greater than 2V as long as
the monitored supply voltage is greater than 3.135V. The comparator output toggles when the monitored
voltage drops below 3.135V. reset generators, supervisors and voltage detectors use circuits similar to the
one shown in Figure 3-3.
Figure 3-4 shows the architecture of a device to monitor multiple power supply voltages. These devices
contain multiple comparators with individual attenuators to facilitate the simultaneous monitoring of dif-

ferent power supply voltages. The outputs of these comparators are logically combined to provide a single logic output to interrupt or reset the processor.
Figure 3-4. Block Diagram of a Three Power Supply Supervisor IC
Effect of Monitoring Accuracy on System Functionality
In the circuit shown in Figure 3-3, suppose we use an ideal bandgap reference source (output voltage is
always 2V), ideal attenuator (its output voltage is exactly 2V when the input voltage is 3.135V), and an
ideal comparator: then, the output of the comparator always toggles exactly when the monitored voltage
is 3.135V. But in reality, the bandgap reference voltage changes with temperature, the output voltage of
the attenuator varies from device to device and there are inaccuracies with the comparator. All these
result in a slight variation of the threshold voltages for each device and across temperature and voltage.
The accuracy of a supervisor is a measure of the variation of threshold with respect to the intended
threshold.
Many off-the-shelf supervisory ICs detect power faults with an accuracy of ±2%. This means that the
actual threshold can vary by as much as 2% of the threshold value across voltage and temperature, and
from device to device. Let’s examine the effect of this accuracy on system functionality and fault detection threshold selection.
Refer to Figure 3-5. If the device is specified at a threshold of 3.3V - 5% (3.135V) with a 2% accuracy,
that device can declare the power supply as faulty anywhere between 3.135 + 2% and 3.135 - 2% (3.2V to
3.072V), shown by points A and B.

Figure 3-5. Fault Detection with Supervisor Accuracy Of 2%
As can be seen, the supervisor can sometimes declare the power supply faulty when it is healthy, or
declare it healthy when it is faulty. The latter is a more serious error, because at lower than the desired
threshold voltage the processor can be mis-executing instructions, which defeats the purpose of using a
supervisor IC.
To avoid such problems, the supervisor threshold should be set such that the entire power supply fault
detect range lies within the operating voltage range of the processor. In this case, if the supervisor threshold is set at 3.2V, then the voltage range in which the supervisor can declare the power supply faulty is
between 3.14V to 3.26V, thus avoiding the condition under which the processor is operating at a voltage
less than its threshold (3.3V - 5%).
Figure 3-6. Fault Detection with Supervisor with Correct Threshold
In the example shown in Figure 3-6, the threshold value of the supervisor was set at 3.2V. The 3.2V
threshold value was actually calculated using the following equation:
Where VTSup - Supervisor Threshold

Asup - Accuracy of the Supervisor
In this example, Vin at 3.3V, VinTol - 5%, Asup - 2%. Substituting these values into the equation above,
VTSup = 3.3 * (1 - (5/100)) / (1 - (2/100)) = 3.2V.
By selecting the Supervisor IC with the threshold at 3.2V or above, the processor is guaranteed to be held
in reset when the power supply voltage is less than or equal to 3.3V - 5%.
Reduced Accuracy Results in Reducing the Power Supply Tolerance
Headroom
Power supply tolerance headroom is the maximum voltage swing allowed for the power supply, across
load and operating temperatures, before being declared faulty as shown in Figure 3-6.
Consider the power supply headroom while using a supervisor IC with an accuracy of 2%. According to
Figure 3-6, the power supply voltage variation should be higher than 3.26V (the highest voltage at which
the supervisor would declare the supply faulty) all the time, or a power supply head room of 1.1%! Typically, power supplies have an output tolerance of about 3% across load and temperature, or the power
supply voltage can swing from 3.2V to 3.4V. Clearly the choice for the user is either to use a more expensive supply with a power supply voltage variation of 1%, or use a supervisor with better accuracy.
Using a Supervisor IC With an Accuracy Of 1%
From the equation for the same system described above, but using an error of 1%, the supervisor selected
should have a threshold of 3.17V. The upper limit of the fault detect range is 3.19V and is still less than
the lowest output voltage of the power supply, -3.2V, and a power supply with a voltage variation of 3%
can be used.
The board can be operated reliably with a lower cost power supply with larger output voltage tolerance by
using a more accurate supervisor. The ispPAC-POWR1220AT8 device offers an accuracy of 0.2% (typical) and 0.7% (maximum).
Effects of Fault Detection Delay
Fault detection delay is the duration from the time the power supply voltage drops below the threshold of
the supervisor (with very high accuracy), to the time the output of the supervisor toggles, indicating the
fault.Reset Generators & Supervisors 3-7
Power 2 You: A Guide to Power Supply Management and Control
Reset Generators & Supervisors
Figure 3-7. Effect of Fault Detection Delay On Board Operation
In Figure 3-7, the 3.3V supply starts to fail. The power supply supervisor detects the power supply failure
and signals the processor. As can be seen from Figure 3-7, the longer the supervisor takes to report the
fault, the lower will be the power supply voltage.
For example, the power supply voltage is decaying at a rate of 1V per millisecond. The supervisor precision is very high, which allows the effects of the accuracy described above to be ignored and is set at the
threshold of 3.3V - 5%. Let us examine two cases: Fault detection delay is 1ms and 50s.
If the Fault Detection Delay is 1ms:
Because the power supply output voltage continues to drop, by the time the processor is reset its power
supply voltage would be much less than the low voltage threshold (about 2V), which means that the processor was executing code until the supply reached 2V! Most likely the processor was mis-executing
instructions or locked up. The purpose of the supervisor IC is defeated.
If the Fault Detection Delay is 50µs:
By the time the supervisor output is active, the processor voltage would have been reduced by about
50mV from its threshold of 3.3V-5%. Again, the processor operation is not guaranteed at this voltage.
Now, if the threshold was set 50mV above the 3.3V-5% level, the processor would be reset by the time
the power supply crossed the operational threshold.
As can be seen, in this application the fault detection delay of 1ms is unacceptable. But a fault detection
delay of about 50s requires the threshold to be set 50mV above the minimum operating power supply
voltage threshold.
The supervisor threshold for reliable operation should consider both the accuracy as well as the fault
detection delay. Many applications use over-voltage monitoring; that is, if the power supply voltage
reaches above the operating voltage range, either the faulty power supply itself is turned off, or a “crowbar” mechanism is turned on by shorting that power supply output voltage to ground, protecting the
devices on the circuit board. Speed of over-voltage detection, in this case, is even more important than the
under-voltage fault detection.

3-8 Reset Generators & Supervisors
The previous example considered only one power supply voltage and used a very accurate supervisor IC.
In reality, the number of power supplies that the supervisor should monitor is more than one. The supervisor should be able to monitor all supplies simultaneously for fault and should be able to detect power supply faults with minimum fault detection delay.
Fault detection delay of 1ms or higher is typically seen in circuits that use a microcontroller to monitor
voltages using their on-chip ADC.
Supervisors Built Using ADC and a Microcontroller are Slow
Some applications use a microcontroller to monitor all the power supplies using an on-chip Analog to
Digital Converter and an analog multiplexer. The monitoring algorithm, which typically is initiated by an
interrupt once every 5 or 10ms, digitizes each power supply voltage, one supply at a time in a round robin
format. The ADC sample is compared with the internally stored threshold. If the ADC read value is lower
than the threshold, an output port pin (reset or interrupt pin) is toggled to indicate the power supply fault.
Because the voltage monitoring algorithm is activated by the real time interrupt, the speed of fault detection is also determined by the delay between interrupts (5ms to 10ms). This is too slow for power supply
fault detection. The only perceived advantage of a microcontroller is that it offers a flexible interface that
lets designers change the power management algorithm after the board is assembled. However, designers
typically avoid changing the microcontroller code. Because there are no software simulators available,
any change in the code requires extensive circuit board testing. Consequently, the perceived advantage of
flexibility is not real.
In order to meet the reliability needs, which include supply fault detection accuracy as well as speed of
fault detection, it is advisable to use hardware supervisors instead of microcontrollers. To meet the flexibility needs, the Lattice Power Manager II devices offer programmable analog and programmable digital
functions, while providing superior accuracy and fault detection speed. For example, the ispPACPOWR1220AT8 device monitors 12 power supplies simultaneously and has a fault detection delay of
16s.
Other Factors Contributing to Increased Reliability
The other factors to be considered for reliable power supply fault detection are:
Glitch filter – Power supplies are usually fairly noisy during the circuit board operation. The noise can
be due to power supply output ripple or to transient currents in the system due to device operation, etc.
This noise can result in a randomly toggling supervisor output. To prevent this, supervisors have a glitch
filter that generates a clean input to the threshold comparators. Power Manager II devices support a 64s
glitch filter for each input.
Hysteresis – A small amount of hysteresis is added to the threshold comparators to prevent the outputs
from toggling multiple times, due to power supply noise, when the power supply voltage is at its threshold. In Power Manager II devices, the hysteresis is set to 1% of the threshold voltage. The hysteresis does
not affect the accuracy of the threshold because the hysteresis transition requirement is applied after the
voltage crosses the threshold.
Differential Voltage Sensing on a Circuit Board – When monitoring voltage levels of 1.2V and below,
one has to use differential voltage sensing to meet the fault detection accuracy needs of the circuit board.Reset Generators & Supervisors 3-9
Power 2 You: A Guide to Power Supply Management and Control
Reset Generators & Supervisors
Figure 3-8. Ground Voltage Difference Adds Error at Supervisor Input
Figure 3-9. Ground Voltage Difference Error Nullified by Differential Sensing
Newer fabrication processes with smaller transistor geometries stipulate reduced core supply voltage and
range such as 1V with a ±50 mV range. If these voltage rails are monitored from a central location, one
should consider the ground voltage difference between the monitored node and the supervisor IC. For
example, in Figure 3-8, if the ground voltage difference between the CPU and the voltage monitoring
device using a single ended sensing method is about 20mV, and if the actual voltage as seen by the CPU
is 30mV, the supervisor IC sees a 30mV + 20mV = 50mV rise from the target value, which is a fault, and
interrupts the processor or holds the processor in reset even when it could operate.
If the ground voltage difference between the supervisor IC and the CPU is -20mV, the monitor IC does
not see a fault even when the supply voltage is lower than its minimum operating threshold level. This
results in an unreliable fault detection circuitry.

3-10 Reset Generators & Supervisors
The safest solution is to use differential voltage sensing (Figure 3-9). Here the ground voltage difference
between the CPU and supervisor IC becomes a common mode voltage at the supervisor and its input difference amplifier cancels the common mode voltage before feeding it to the comparator.
Ensuring Deterministic Behavior Under Fault Conditions Through Simulation – The response of a
circuit board depends on the power supply failure. As a result, the supervisor is expected to perform different functions depending on the supply that failed. For example, if the core voltage of a CPU failed, the
supervisor has to activate the reset signal and start the board power shutdown. However, if one of the
redundant supplies failed, the supervisor has to interrupt the processor. To guarantee functional reliability,
one should ensure that the design implemented in the Supervisor IC responds to the supply faults correctly. The easiest method is to simulate the design with different types of faults using software, rather
than conduct the hardware regression tests.

The ProcessorPM-POWR605 in the circuit diagram in Figure 3-10 monitors six supplies directly by configuring each of the monitoring comparator inputs to the fault threshold. Two digital outputs of the ProcessorPM-POWR605 device are configured as CPU_reset and WDT_Int. The CPU_Reset signal
supports programmable pulse stretching up to 2 seconds. For example, if the programmable delay is set to

their respective threshold levels. The WDT_Int signal is activated if the WDT_Trig input is not toggled
before the watchdog timer expires. The watchdog timer delay can be programmed from 32s to 2.5 minutes. The reset_in input is used to activate the CPU_Reset signal from an external input such as a manual
reset input signal.

configuration can be used to provide over-voltage protection.
Relevant Power Manager II ICs
Devices such as the ispPAC-POWR1014/A can be used to monitor up to 10 rails. These devices support
dual programmable threshold comparators for each of the inputs that enables them to monitor for both
over and under-voltages at the same time. The ispPAC-POWR1220AT8 device can be used to monitor up
to 12 rails. These devices also support differential sense inputs that can be used to monitor lower voltage
supply rails on a larger board more accurately.Power 2 You: A Guide to Power Supply Management and Control

Power Supply Sequencing
4.1 Introduction
The number of power supplies (DC-DC Converters, LDOs, Voltage References) in a circuit
board is determined by the number of multi-voltage devices used in its payload section. These
devices also determine power supply sequencing. Power supply sequencing indicates that all
supplies on the board should not be turned on arbitrarily at any time, but instead should be
turned on or off in a prescribed sequence.
For example, on a circuit board a device with 3 supplies of 3.3V, 1.8V and 1.2V, usually the
lowest voltage rail should be turned on first, followed by the larger voltages. The turn on
sequence is 1.2V, 1.8V and finally 3.3V. Turning these supplies on in this sequence can be
implemented easily by connecting the power good signal from the 1.2V supply to the enable
signal of the 1.8V supply, and finally connecting the 1.8V power good signal to the enable signal of the 3.3V supply. However, when there are multiple devices, each with its own sequencing requirements, the logic required for sequencing can become complex.
Sequencing Power Supplies with Conflicting Sequencing
Requirements
What if there is a second device on that same board with supplies of 3.3V, 2.5V and 1.2V, but
the supplies must be turned on starting with the highest voltage? This is further complicated by
the fact that 3.3V is the main input supply. Now the designer is required to implement sequencing using the fewest possible supplies.
In such cases, MOSFETs are used to gate the supplies that conflict with conventional sequencing. The circuit in Figure 4-1 shows one such arrangement.Power 2 You: A Guide to Power Supply Management and Control
4-2 Power Supply Sequencing
Figure 4-1. Sequencing Supplies to Meet Conflicting Sequencing Requirements
This circuit uses the 3.3V supply to generate the remaining supply rails on the board. Because Device 1
requires 3.3V last and Device 2 requires 3.3V first, the 3.3V is applied to Device 2 with the remaining
supplies. Then, the power sequencer enables 2.5V, followed by 1.2V, completing the powering up of
Device 2. Next, because the 1.2V for Device 1 is already on, the power sequencer turns on the 1.8V, followed by the 3.3V that is enabled through the MOSFET.
One could have implemented this sequencing by using one more 3.3V supply and turning it on only when
Device 1 needed it. However, that would increase the board cost. Adding a second multi-voltage device
with its own sequencing requirements can make the sequencing more complex.
There are other factors that contribute to increased supply sequencing complexity.
Other Factors Adding Complexity to Sequencing Algorithm
Number of Board-Mounted Supplies is Increasing
Modern circuit boards use several multi-voltage ICs such as ASICs, CPUs, memories, and FPGAs. Due
to the high level of integration, fabrication processes and support for multiple interface standards, each of
these devices can require three to five power supplies. Furthermore, some of these devices require a nonstandard, low voltage core supply. So, it is not uncommon for boards to require five to ten supplies!
Sequencing the power supplies to meet the needs of each of the devices can be quite complex.
Abort Sequencing if Any Supply Fails During Power-Up
Supplies usually fail when they are turning on, leaving some of the devices partially powered. Often
some of these devices can only withstand the partially powered condition for a limited time. To mitigate
such conditions, the sequencer is required to abort supply sequencing when any supply fails to turn on
within a given period. In this case, the sequencer is required to monitor supplies and monitor time during
the supply sequencing.

Power Supply Sequencing 4-3
Power-Down Sequencing
Some devices require the power supplies to be turned off in the reverse order of the turn on sequence to
prevent undesirable side effects, such as excessive current consumption on one of the rails that can damage the circuitry. Removing power to all DC-DC converters at the same time may not guarantee safe shut
down in these cases, because the capacitors connected to the DC-DC converter outputs may not all discharge at the same time.
Minimum Duration Between Two Supplies During Turn On
This condition is usually discovered during the board debug phase, when a board does not turn on reliably. The best solution is to be able to easily increase and/or decrease the delay between sequencing
steps.
Accommodating Changes to Sequencing Observed During the Board Debug Phase
Board design engineers are required to meet the sequencing requirements of all devices on the board during the final phases of the board design. To prevent a board re-spin, power sequencing sections are
designed with ample provisions for additional components and 0Ω jumpers. This increases the number of
components but still may not avoid a jumper wire or two.
Power Supply Ramp-Rate Control
Some devices require that the supply be turned on with a slow ramp to minimize current in-rush. To meet
this requirement, designers feed the power through a MOSFET and the ramp-rate is controlled through
the gate of the MOSFET.
Turning Unused Power Domains Off to Save Power During Inactive Periods
In order to reduce overall board power dissipation, designers turn off sections of the board when they are
not in use. This means that when a power domain is turned on, the supplies in that domain need to be
turned on in a sequence. Sometimes, to avoid disruption to the operation of the rest of the board, a shut
down sequence may be required to minimize current glitches in the system.
4.2 Flexible N-Supply Sequencing Using Power Manager II
II Devices
Power Manager II devices offer an ideal set of features, such as a PLD, multiple programmable threshold
comparators, multiple programmable duration timers and multiple charge pumps, that can be used to turn
MOSFETs on/off with programmable ramp-rate control. The resulting power management algorithm is
very flexible because all features of the device, as well as the sequencing algorithm, can be controlled by
the LogiBuilder utility in the PAC-Designer software tool. The sequencing algorithm also can be simulated to ensure that the algorithm is able to handle all of the faulty conditions.
Figure 4-2 shows a typical power supply sequencing implementation using the ispPAC-POWR1014A
device. In this circuit, the DC-DC converters are controlled by the ispPAC-POWR1014A device. While it
is possible to interface with the active-low enable signals directly with the ispPAC-POWR1014A device
outputs, an external transistor may be necessary to interface with active high enable signals.
Voltages are Monitored During/After Sequencing
All DC-DC converter voltages are monitored by the programmable threshold comparators of the ispPACPOWR1014A device. In this circuit, the ispPAC-POWR1014A device uses a programmable algorithm
designed using the PAC-Designer software tool to turn the DC-DC converters on/off through the DC-DC Power 2 You: A Guide to Power Supply Management and Control
4-4 Power Supply Sequencing
converter’s enable pins. During supply sequencing, the ispPAC-POWR1014A device will monitor the
output voltage of each of the DC-DC converters using the on-chip programmable threshold precision
comparators.
The power supply sequencing is controlled by the open drain output pins of the ispPAC-POWR1014A.
These output pins are controlled by the on-chip PLD. The sequencing algorithm is implemented using the
LogiBuilder utility in the PAC-Designer software. Using the LogiBuilder utility, one can implement the
following sequencing methods:
1. No sequencing – Here all the supplies are turned on at the same time and no sequencing is necessary.
2. The ispPAC-POWR1014A device waits for all the supplies to reach their operating levels and then
generates a power good signal for the board to begin the initialization process. Operating voltage levels are higher than the lower voltage limit and less than the over-voltage limit.
3. Closed loop sequencing – This is a sequence where one supply is turned on only after the previous
supply has reached its operating levels.
4. Time-based sequencing – The power sequencer inserts a time delay between each of the supplies without first checking if the first supply reached its normal operating level.
5. Closed loop sequencing with time delay – The second supply is turned on a fixed time after the first
supply is on and is within its normal operating voltage level.
6. The supply reaches its normal operating condition within a period of time. Often, supplies fail during
turn on. To prevent the locking up of sequencing while waiting for this failed supply, the algorithm
turns the supply on and, if the supply does not reach its normal operating voltage levels within a specified time, then the supply is considered faulty and action for incomplete sequencing is initiated.
7. Turn on multiple supplies with a watchdog timer – In this case, supplies are turned on using any of the
previous methods. After all the supplies are turned on, the power sequencing algorithm ensures that all
supplies are on within the total watchdog timer period. If the watchdog timer expires, the faulty
sequence action is initiated.
Any or all of these sequencing methods can be implemented easily using the LogiBuilder utility within
the PAC-Designer software. LogiBuilder enables implementation of a power management program using
six types of intuitive, user friendly and powerful instructions. The user has the flexibility to apply these
turn-on rules to each supply, or for groups of supplies, simply by using the appropriate LogiBuilder
instructions to manage that supply.Power 2 You: A Guide to Power Supply Management and Control

Power Supply Sequencing 4-5
N-Supply Closed Loop Sequencing Algorithm
This section describes a closed loop N-supply sequencing algorithm implemented in the ispPACPOWR1014A device, as shown in Figure 4-2. Table 4-1 provides a detailed explanation of LogiBuilder
instructions, along with the associated sequencing method.
Figure 4-2. Flexible N- Supply Sequencing using the ispPAC-POWR1014A Device
The power management algorithm is implemented in LogiBuilder in a sequence of steps using the LogiBuilder instructions. The Power Manager II device then executes these steps to sequence the supplies on
the board. In this example there are N supplies.
During each of the first N steps, the LogiBuilder instruction turns on a power supply and waits for the
voltage to reach its operating limit.
1. Turn on DC-DC/LDO #1, enable the converter and wait for its output voltage to reach the operating
range. The ispPAC-POWR1014A device uses two precision programmable threshold comparators to
monitor a given voltage rail. One comparator threshold is set to the lower voltage limit of that voltage
rail and the second comparator threshold is set to the over-voltage limit. A DC-DC converter is in its
operating limit when its voltage is between the over and the under-voltage limits.
2. Turn on the DC-DC/LDO #2 enable signal and wait for its voltage to reach operating range.
3. Turn on the DC-DC/LDO #3 enable signal and wait for its voltage to reach its operating range (Same
function as step 2).
4. Continue turning on supply #4 (Same function as step 2).
5. Continue turning on supply #5 (Same function as step 2).

Q. Shut-Down Signal Interrupt Routine – When the shut down signal becomes active, jump to step O.
N-supply Closed Loop Sequencing with Failure Monitor Algorithm
In the N-supply closed loop sequencing algorithm shown above, a supply failure would hold up the
sequence forever. While this phenomenon may be acceptable for most applications, some ICs may be
sensitive to being in a partially powered state for extended periods. In that case, the algorithm can be
modified to include turn on with monitor mode. For example, if a device is sensitive to the duration of a
partial power condition at step 2 of the algorithm above, it can be changed to the following:
1. Turn on DC-DC #1, enable converter and wait for its output voltage to reach operating range.
2. Turn on DC-DC#2 enable signal and wait for its voltage to reach operating range within 5ms. If the
supply does not reach operating range within 5ms jump to step O or else proceed to turn off the rest of
the supplies.
3. Turn on DC-DC #3 enable converter and wait for its output voltage to reach operating range.
4. Continue turning on supply #4, similar to step 3.
5. Continue turning on supply #5 with fault monitor, similar to step 2.
N. Continue turning on supply #N, similar to step 3.
O. If all the supplies are within the operating range, activate the power good signal. If any of the supplies
are faulty, turn all the supplies off and activate the Sequence_Fail signal.
P. Wait for Recycle_Power to become active and then jump to step 1.
Applying LogiBuilder Instructions to Sequencing Methods
As stated earlier, the LogiBuilder utility in the PAC-Designer software tool provides instructions to
directly support different types of sequencing. Figure 4-3 shows the block diagram of a power sequencing
circuit. Table 4-1 lists different LogiBuilder instruction sequences to implement the different sequencing
methods used to enable the power to Device #1.Power 2 You: A Guide to Power Supply Management and Control

Any of these sequencing methods can be used for any supply or group of supplies. The timer values can
be set to any value between 32s and 2 seconds.
Advantages of Power Manager II-based Supply Sequencing
The sequencing of supplies is completely programmable. Designers can adjust the turn on or turn off
sequence and the associated timing to provide reliable board start up after the board is assembled. No
board re-spin is needed. Once the supplies are sequenced the ispPAC-POWR1014A device monitors all
of the supplies for faults.
Additional Power Management Functions that can be Integrated into Power
Manager II
In this circuit, the ispPAC-POWR1014A device provides flexible sequencing. The other functions that
can be integrated into an ispPAC-POWR1014A device are:
1. Voltage supervision – Monitor all supplies after sequencing for fault and generate an interrupt signal
such as a low voltage detect.
2. Reset generation – After the sequence is complete, the ispPAC-POWR1014A device can be used to
release Reset for the CPU.
3. Hot-swap controller – If power supply sequencing is required in a positive voltage hot-swappable
board, the hot-swap function can also be integrated.
4. Voltage measurement – In addition to all of the supplies being monitored for faults, an external
microcontroller can measure individual voltages through the I2
C interface.
5. Fault logging – In case of a fault, the ispPAC-POWR1014A device can output the status of all comparators to an external PLD for logging into a non-volatile memory to aid debug.
Applicable Power Manager II Devices
Power Manager II devices that can be used for implementing sequencing are the ispPACPOWR1220AT8, ispPAC-POWR1014/A, ispPAC-POWR607 and ProcessorPM-POWR605.

4.3 Sequencing With MOSFETs and DC-DC Converter
Enables
In some cases, to meet the device’s sequencing needs without using additional DC-DC converters, MOSFETs are required. Figure 4-4 shows one such circuit, where a ispPAC-POWR1014A device controls the
DC-DC converter’s enable signals as well as an N-Channel MOSFET. In this circuit the MOSFET is used
to enable 3.3V to Device 1 after all of its other supplies are turned on.
To turn-on an N-Channel MOSFET on a 3.3V rail, its gate potential should be at least 8V. Designers
either use the 12V supply (if available on the board) or a charge pump IC to generate 8V or higher. The
ispPAC-POWR1014A device integrates two MOSFET gate drivers based on integrated charge pumps
that can generate up to 12V. The charge pump voltage can be programmed to 6V, 8V, 10V or 12V. In addition, the MOSFET turn on ramp-rate also can be controlled using the programmable current source feature of the MOSFET driver. The gate drive source current can be set to 12.5A, 25A, 50A and 100A.
The higher the current setting, the faster the MOSFET turn-on time.
Circuit Operation
In the circuit shown in Table 4-4, the ispPAC-POWR1014A device is controlling the enable signals of
1.8V, 2.5V and 1.2V DC-DC converters. The MOSFET driver of the ispPAC-POWR1014 device is used
to turn the MOSFET Q1
on/off. The sequencing logic is implemented in the PLD using the LogiBuilder
utility in the PAC-Designer software tool.
After sequencing is complete, the ispPAC-POWR1014A activates the Power_Good signal. If the
sequencing fails to complete, the algorithm activates the failed (to complete the sequence) signal.
The Shut_Dn signal is used to turn the supplies off in reverse sequence.

Hot-Swap Controllers
5.1 What is a Hot-Swap Controller?
Hot-swap controllers limit the inrush current when a circuit board is plugged into a live backplane. In addition, these devices offer over-current, over-voltage and under-voltage protection
to the circuit board. Figure 5-1 shows the block diagram of a typical hot-swap controller implementation for a positive backplane power supply rail. RS
is the current sense resistor. The
MOSFET Q1
is used to control the current through the circuit. The resistors R1
, R2 and R3
are
used to monitor the backplane voltage. The hold-off capacitor, Ch
, is used to provide power to
the board when the backplane voltage briefly drops below the low operating voltage (undervoltage) threshold (say, for less than 10ms).
Figure 5-1. Positive Rail Hot-Swap Controller
When the card is plugged into the live backplane, the hold-off capacitor, Ch
, begins to draw a
large amount of current from the backplane. The hot-swap controller limits the current in-rush
by controlling the voltage applied to the MOSFET gate using the voltage across RS
as feedback. The MOSFET will operate in this current limit mode until the capacitor Ch
is fully
charged.
During the brief capacitor charging period, the inrush current drawn from the backplane often
can be significantly higher than the normal board operating current. As a result, the backplane
voltage can dip below the under-voltage threshold momentarily for the other cards attached to

the backplane. The charge stored in the capacitor, Ch
, keeps the card operating during this brief voltage
dip period.
Hot-swap controllers are also required to isolate the board from the backplane in case it develops a fault
during operation. For this purpose, the hot-swap controller will monitor the current through the sense
resistor RS
. When the voltage across the resistor RS
increases beyond its threshold value, the hot-swap
controller turns the MOSFET off.
If the backplane voltage drops below the under-voltage threshold or goes above the over-voltage threshold, the power supply to the load is shut off by turning the MOSFET off.
Figure 5-2. Negative Supply Hot-Swap Controller
One of the popular backplane voltages in the telecom industry is -48V. Hot-swap controllers for negative
supplies use the current limiting MOSFET on the negative supply limb, as shown in Figure 5-2. Functions of negative rail hot-swap controllers are similar to the positive voltage hot-swap controllers
described above.
Hot-Swap Circuit Design Considerations
In a hot-swap controller circuit the MOSFET will be required to withstand high levels of power dissipation while the hold-off capacitor is being charged. The suitability of the MOSFET for this purpose is
determined by its Safe Operating Area (SOA) curves.
When a circuit board fault occurs, the current through the MOSFET can increase significantly. If the
MOSFET is not quickly turned off, the peak power dissipated on the MOSFET can damage it. hot-swap
controllers are also required to monitor over-current conditions and initiate either a fold-back current limiting mechanism or turn the MOSFETs off. Usually under high current conditions, the MOSFET should
be turned off within approximately 1s. Some hot-swap controllers implement “retry” to turn the board
on if the fault subsequently clears on its own accord. hot-swap controllers are also required to monitor for
low voltage conditions and shut the board off when such a condition occurs.
5.2 Implementing a Positive Supply Hot-Swap Controller
Using Power Manager II Devices
There are many types of hot-swap controllers with different current control and other monitoring mechanisms. Usually, the complexity of a hot-swap controller depends on the power dissipation requirement of
a circuit board. This section shows how Lattice Power Manager II devices can be used to implement hotswap controllers that range from the simple to the sophisticated.

Hot-Swap Controller Using Soft-start
Figure 5-3 shows the ispPAC-POWR1014A device implementing a simple hot-swap controller. The principle of operation of this circuit is also called a ‘soft-start’ mechanism.
Figure 5-3. Hot-Swap Control Implemented Through MOSFET Ramp Rate Control
Circuit Operation
In this design, the backplane supply is 5V. The card with the ispPAC-POWR1014A device is plugged into
the live 5V backplane. The ispPAC-POWR1014A device first waits for the 5V backplane voltage to stabilize from the initial contact bounce. After the contact bounce period is complete, the ispPACPOWR1014A turns the MOSFET Q1
on through the Soft_start pin (HVOUT pin). The HVOUT pin
source current is set to a minimum (12.5A). This current charges the MOSFET gate capacitance slowly.
As a result, the MOSFET on-resistance also drops slowly to its final RDS-on value (usually in a few tens
to hundreds of mΩ range). This gradual reduction in MOSFET on-resistance reduces the current in-rush.
This circuit can only be used in low power and low voltage boards. It also requires that the instantaneous
power dissipated by the MOSFET does not violate its safe operating area specification.
Soft-start algorithm:
1. Wait for 5V to be continuously on for 100ms and ensure it is within tolerance by monitoring Inp_5V
signal.
2. Turn on Q1
by setting soft-start signal to logic 1.
3. Wait until supply at 5V load is within tolerance by monitoring the Out_5V signal.
4. Enable the 5V load through the Start_5V_Load signal.
Programmable Features
The following parameters can be changed to make this circuit meet a wide range of application needs:
• Comparator thresholds can be changed to suit difference backplane voltages, e.g., 5V or 3.3V. The softstart function for 12V can be implemented using a P-Channel MOSFET and driven by one of the logic
outputs. Negative rail soft-start can be implemented using N-channel MOSFETs.
• Contact de-bounce period can be changed from 50ms to 2 seconds.

• MOSFET turn on ramp rate can be set using the four current settings available for each HVOUT pin.
• Design can be used to implement a dual hot-swap controller for dual supply backplanes using two
MOSFET drivers in the ispPAC-POWR1014 device.
Integrate Other Board Power Management Functions into a ispPAC-POWR1014A Device
This design consumes a very small portion of the ispPAC-POWR1014A device. The remaining resources
can be used to implement board power management functions such as power sequencing, voltage supervision, reset generation and watchdog timer.
In addition, one may also include faulty board identification and protection. If the board is healthy, the
voltage at the hold-off capacitor should stabilize within a short period of time (say, 5ms). If the board is
faulty (drawing more current than expected), the voltage at the capacitor will drop to a value less than the
lower voltage threshold. When such a condition arises, the MOSFET is turned off immediately. This prevents continuous overloading of the backplane.
One can also monitor the backplane voltage to generate early warning to the load circuit for safe turn off.
Backplane voltage and other on board rail voltages can be measured using the ispPAC-POWR1014A
device’s ADC via the integrated I2
C interface.
Applicable Power Manager II Devices
In this example, a ispPAC-POWR1014A device was used to implement the soft-start function. However,
the soft-start control application can also be implemented in ispPAC-POWR1220AT8, ispPACPOWR1014 and ispPAC-POWR607 devices. The ispPAC-POWR607 devices, however, do not support
the programmable ramp-rate control feature.
Hot-Swap Controller with Hysteretic Current Limit Mechanism
When designing hot-swap controllers for boards with higher power dissipation, or when one is not able to
guarantee the MOSFET safe operating area limits are not violated during the hot-swap operation, or when
the backplane inrush current is to be limited to prevent disruption to other boards plugged into the same
backplane, the following circuit (Figure 5-4) should be used. This circuit begins to operate with the
MOSFET Q1
turned on. The current starts to increase to charge the capacitor Ch
. When the current
exceeds the preset value, the logic in the hot-swap controller turns the MOSFET off. At that time, the current starts to decrease. When the current drops below the preset value, the logic turns the MOSFET on
and the current starts to increase again. This method of limiting the current to a preset value by turning
the MOSFET on/off is called hysteretic mode of operation. Power 2 You: A Guide to Power Supply Management and Control
Hot Swap Controllers
Hot-Swap Controllers 5-5
Figure 5-4. Hot-Swap Controller with Hysteretic Current Limit
There are two additional blocks in comparison to the soft-start control circuit shown in Figure 5-3: current monitoring and quick shut-off control. The name of ispPAC-POWR1014A device’s high voltage
MOSFET gate drive pin has been changed from Soft_start to Hyst_Ctrl.
Principle of Operation of the Hysteretic Control Mechanism
Figure 5-5 shows plots of the gate drive of the MOSFET Q1
, current through the MOSFET and the voltage across the capacitor Ch
. When Hyst_Ctrl signal is turned on, Q1
’s gate capacitance starts to charge. At
the same time, the current through the MOSFET also begins to increase. The current through the MOSFET passes through the sense resistor RS
. The current sense amplifier (CSA) outputs a current proportional to the voltage dropped across RS
into series resistors R1
and R2
. The voltage drop across R1
and R2
is monitored by the ispPAC-POWR1014A device through the signal I_In (one of the VMON pins). The
comparator output of this VMON pin toggles when the current through RS
exceeds the maximum allowable limit (IH). As a result, the logic equation in the PLD turns the Hyst_Ctrl pin off. When the Hyst_Ctrl
pin is at logic 0, the MOSFET gate starts to discharge, throttling the current through the MOSFET channel, and the current through the MOSFET begins to drop. The voltage at the I_In pin reduces. When the
voltage drops below the I_In pin threshold (IL), the logic equation in the ispPAC-POWR1014A device
turns the MOSFET back on.
This cyclic throttling action maintains the average current to a value determined by the current threshold
settings. This technique provides many of the advantages of linear current control while sidestepping
many of the potential stability issues.

Figure 5-5. Hysteretic Current Control Through the Capacitor
Turning MOSFET Off Under Short Circuit Conditions
To prevent excessive current drain from the backplane and to protect the MOSFET against damage due to
excessive power dissipation during a short circuit event, the MOSFET should be turned off within 1s
from the time the current reaches a dangerous level. In Figure 5-4, the ispPAC-POWR1014A device’s
digital input pin IN1 is driven to Logic 0 by the transistor Q2
when the current through the 5V supply rail
exceeds short circuit current limit. The voltage across R2
is 0.7V when the current through RS
reaches the
short circuit current level. The logic equation in the ispPAC-POWR1014A device turns the MOSFET off
immediately within 200ns.
Hysteretic Hot-Swap Control Algorithm
The algorithm is divided into two sections:
• Logic equations for hysteretic control and fast-acting MOSFET shut down during a short circuit event
• Sequence control for overall hot-swap event control
Equation 1 implements the hysteretic control. The signal En_Hot_Swap turns the hot-swap controller on
or off. This signal is turned on by the sequence control algorithm after the contact-de-bounce period. The
Hyst_Ctrl (D-type flip-flop) is turned off when the I_In signal voltage exceeds the over-current limit level
and turns back on when the I_In signal drops below the threshold. The comparator hysteresis provides the
delay between turn-on and turn-off.
Equation 2 is a combinatorial equation that turns the MOSFET off as soon as the Short_Ckt signal is
equal to logic 0.

Sequence control:

2. Turn on the hysteric hot-swap action by turning on En_Hot_swap signal.
3. Wait for supply at 5V load is within tolerance limits by monitoring the Out_5V signal.
4. Enable the 5V load through the Start_5V_Load signal.
5. During normal operation, if an over current or under-/over-voltage supply fault occurs for a period
greater than the hold-off period (5ms to 10ms), then shut the MOSFET off and retry.
Programmable Features
This circuit offers many programmable features that make it suitable for a wide range of applications.
• Comparator thresholds can be changed to suit different backplane voltages, e.g., 5V or 3.3V.
• Contact de-bounce period can be changed from 50ms to 2 seconds.
• Over-current and short circuit current levels can be set independently.
• The design can be used to implement dual hot-swap controllers for dual supply rail backplanes.
• Hold-off time is programmable from 2 to 100ms (time during which the MOSFET should be left on
under supply fault). After this period expires, the MOSFET is turned off.
The ispPAC-POWR1014A Device Can Integrate Other Board Power Management
Functions
The difference between the soft-start method and hysteretic control in the algorithm is the addition of two
logic equations. As a result, the remaining resources can be used to implement power sequencing, voltage
supervision, reset generation and watchdog timer functions for the board.
For faulty board identification and protection, add a watchdog timer when monitoring the load voltage
immediately after the hysteretic control loop is turned on (after step 4). If this timer expires before the 5V
reaches the operating threshold level (implying a fault that is preventing the charge build up in the capacitor Ch
), turn the MOSFET off and turn an LED on, indicating the supply fault.
Add backplane voltage monitoring logic to provide early warning to the load circuit for safe turn off.
Applicable Power Manager II Devices
This example used the ispPAC-POWR1014A device to implement the hysteretic control hot-swap function. However, the hysteretic control can also be implemented in ispPAC-POWR1220AT8, ispPACPOWR1014 and ispPAC-POWR607 devices.
Advantages of Using Power Manager II Devices for Hot-Swap Controller
There are many hot-swap controllers in the market. Designers have to use these hot-swap controller
devices in addition to the board management function. The Power Manager II device reduces the cost of
implementation by integrating the hot-swap controller function along with overall board management
into a single chip.
In addition, the design can be used across a wide range of applications.Power 2 You: A Guide to Power Supply Management and Control
5-8 Hot-Swap Controllers
12V/24V Hot-Swap Controller
The operating principle of this circuit is the same as that of the 5V hot-swap controller with hysteretic
control mechanism. Two additional features are added to make it compatible with the 12V hot-swap function. These features are an external charge pump and limiting operation of the MOSFET within its safe
operating range.
The maximum MOSFET gate drive voltage of ispPAC-POWR1014/A and ispPAC-POWR1220AT8
devices is 12V. However, to turn the N-Channel MOSFET on the 12V or 24V rail, one has to drive its
gate voltage to 22V or 34V, respectively (about 10V above the rail voltage). To achieve this high voltage,
the following circuit (Figure 5-6) implements an external charge pump using diodes, capacitors and a
transistor.
The operating principle of the external charge pump is as follows (Figure 5-6). The C_Pmp signal (ispPAC-POWR1014A HVOUT pin) toggles between 12V (for 32s) and 0V (for 8s) cyclically. When the
C_Pmp signal is at 0V, the capacitor C1
gets charged to backplane voltage of 12V through the diode D1
.
At this time the transistor Q2
is off. When the C-Pmp signal toggles up to 12V, the C1
voltage gets added
to the C_Pmp pin voltage, resulting in the generation of approximately 24V at the junction of C1
and D1
.
This voltage turns Q2
on and charges the capacitor C2
to about 22V through the diode D2
. This voltage is
sufficient to turn the MOSFET Q1
on.
The transistor Q3
, driven by the S_Dn signal, is used to shut the MOSFET Q1
off by discharging the
MOSFET Q1
gate and C2
when there is a fault.

In the oscilloscope plot shown in Figure 5-8, the green trace is the current through the MOSFET and the
pink trace is the voltage across the capacitor. As can be seen, the current is limited to 2A until the voltage

When the circuit is turned on to a short circuit, the power feed begins as usual. If the capacitor voltage
does not reach 9V within 10ms, the MOSFETs are turned off and the circuit waits for a retry command.

• Logic equations for the external charge pump operation
• Logic equations for hysteretic control and fast-acting MOSFET shut down during a short circuit event
• Sequence control for overall hot-swap event control
Toggle_C_Pump is an internal variable used to generate 8 s wide pulses.

count-down is complete. When the timer gate signal is connected to the inverted Timer_TC (Figure 5-

Equation 5 controls the MOSFET drive circuit. The Toggle_C_Pump signal is used to drive the external

• En_Hot_Swap – Controlled by the sequence control
• (NOT I_IN_2_A AND NOT OUT_12V_GT_6V) – Hysteretic control that limits the current to less

the voltage across the MOSFET are monitored using two potential dividers of 43K and 3.3K. The 6V
zener diode is used to protect the ispPAC-POWR607’s input section.
When the blade is plugged into the backplane, the ispPAC-POWR607 waits for the contact bounce to settle and then begins to charge the hold-off capacitor, using current pulses instead of a continuous current
feed. The rate of current pulses is programmable to meet the MOSFET's power dissipation characteristics. Once the voltage reaches a preset threshold, the rate of current pulses is increased to hasten the
charging of the hold- off capacitor. After the hold-off capacitor is completely charged, the MOSFET is
fully turned on and the Power_Good Signal is activated. This signal is used to enable the DC-DC converter. The voltage across the MOSFET is monitored by the two voltage monitoring inputs of the ispPAC-POWR607. The programmable threshold set for the first voltage monitoring (Fast Charge Duty
Cycle Threshold) input determines the changeover from slow charging to faster charging of the hold-off
capacitor. The second threshold (End of Soft Start) indicates the completion of the charging of the holdoff capacitor and to fully turn on the MOSFET.
The ispPAC-POWR607 waits for a preset period (determined by the short circuit watchdog timer) for the
voltage across the MOSFET to drop below the fast charge threshold. If the voltage across the MOSFET
does not drop below the fast charge threshold, the MOSFET is turned off, indicating a fault such as a
short circuit. With this implementation, the MOSFET continues to operate within its Safe Operating
Area, even if a short circuit is present.
During normal operation, the ispPAC-POWR607 senses the beginning of a brownout period when the
backplane voltage drops below a preset threshold and initiates an internal programmable timer of 10ms.
If the power supply recovers within that time, the circuit continues to function normally. If the 10ms
timer expires, the hot-swap controller classifies it as an under-voltage event and jumps to the power recycle routine, waiting for the supply to stabilize before initiating a recharge of the hold-off capacitor.
During normal operation, when a card is plugged into the backplane, the backplane supply dips momentarily. During the voltage dip period, all cards use the hold-off capacitor to remain functional. Consequently, the hold-off capacitor loses some charge. When the backplane recovers, the charge in these
capacitors is replenished. This results in a brief current spike, usually less than 100s. This should be
ignored by the hot-swap controller. However, if there is a catastrophic current fault on the board, the hotswap controller should respond to this high current and shut the MOSFET down in less than 1s to prevent fault propagation and to prevent damages to the MOSFET. The transistor Q2
is used to protect the
card when the current fault results in very high current. When the voltage across the current sense resistor
exceeds 0.7V, the transistor Q2
turns on and applies a logical 0 to the digital input of the ispPACPOWR607. The logic equation within the ispPAC-POWR607 then turns on the transistor Q3
. Q3
discharges the MOSFET gate charge, resulting in turning the MOSFET off within 1s.
Controlling Current Inrush While Operating the MOSFET in its Safe Operating Area
The top trace of the oscilloscope in Figure 5-14 shows 10ms wide, 1.5A current pulses charging the holdoff capacitor. The bottom trace is the voltage across the MOSFET while charging a 4700F hold-off
capacitor.Power 2 You: A Guide to Power Supply Management and Control

Figure 5-14. Hold-off Capacitor Charging Current and Voltage Across the MOSFET
Two of the ispPAC-POWR607’s MOSFET drivers drive the MOSFET gate. One MOSFET driver maintains the current amplitude at 1.5A, and the second MOSFET driver controls the modulation rate. In this
circuit, the duty cycle was limited deliberately to one 10ms pulse every 260ms. This limits the worst-case
(during short circuit) average power dissipated by the MOSFET to 1.5A * 48V * 5ms / 260ms = 1.4W.
Hot-Swap Controller Algorithm
• The hot-swap controller algorithm is mainly implemented in an ispPAC-POWR607 device using
sequence control. However, the short circuit over current is monitored using a combinatorial logic
equation because of speed.
Sequence control:
1. Turn-off MOSFET and wait for contact bounce to settle.
2. Until the voltage across the MOSFET drops below 25V, charge the capacitor using 10ms wide 1.5A
pulses repeated once every 260ms. If the voltage does not drop below 25V within 512ms, stop hotswap.
3. After the voltage across the MOSFET drops below 25V, increase the duty cycle to 10ms wide 1.5A
pulses repeated at a rate of 65ms.
4. Wait for the voltage across the MOSFET to drop below 1V and turn the MOSFET on fully.
5. If an over-current condition occurs, turn the MOSFET off and retry once in two seconds.
Customizing the -48V Hot-Swap Controller
The entire hot-swap algorithm can be implemented within the 16-macrocell PLD of the programmable
hot-swap controller. Designers can customize this algorithm to suit their blade requirements. The following parameters of the programmable hot-swap controller can be customized:
• Short circuit watchdog duration: If the hold-off capacitor does not charge in the specified time
period, the MOSFET is shut off.

Applicable Power Manager II Devices
This design is implemented using an ispPAC-POWR607 device. However, the ispPAC-POWR1014A
device can also be used to implement the hot-swap controller if the design requires voltage measurement
through the I2
C interface.
5.4 CompactPCI Board Management
Applications such as CompactPCI or CompactPCI Express use a backplane with multiple power supply
rails.
Figure 5-15 shows the requirements of the hot-swap controller for CompactPCI standard backplane with
voltages of +12V, +5V, +3.3V & -12V. In this design, the +5V and +3.3V rails carry the bulk of the
power.Power 2 You: A Guide to Power Supply Management and Control

Figure 5-15. CompactPCI Board Power Management Including Hot-Swap
The Power Manager II ispPAC-POWR1220AT8 device has been used to implement not only the hotswap controller but also the entire circuit board’s power management, as shown in Figure 5-15. In this
design, the 5V and 3.3V hot-swap controllers use the hysteretic current control mechanism (as described
in the section “Hot-Swap Controller with Hysteretic Current Limit Mechanism” on page 5-4) and the +12
and -12V use the soft-start control mechanism (described under “Hot-Swap Controller Using Soft-start”
on page 5-3). The +12V rail uses a P-Channel MOSFET.
CompactPCI Board Management Algorithm
The hot-swap controller, after initiating the hysteretic and soft-start functions, waits for the board supplies to reach normal operating levels within the watchdog time period and then activates the Healthy#
signal.

If the hot-swap function fails, the Healthy# signal is not activated and the main system does not activate
the PCI card. One can then re-initiate the hot-swap function by extracting and re-inserting the board into
the backplane. After all hot-swapped rails reach normal operating value, the ispPAC-POWR1220AT8
device initiates the sequencing of 2.5V and 1.8V supplies. After all supplies are stable (including the onboard sequenced supplies), the CPU reset signal (CPU_RSTb) is activated. If any supply fails, the
brown_out signal is activated.
Programmable Features
The circuit shown in Figure 5-16 can be customized for the following:
• Over-current for 5V and 3.3V
• Sequencing of board mounted voltage
• Protecting against board faults – Turn off all hot-swap MOSFETs
• Generating other board specific power management signals
• Measuring voltage and current
• Trimming and margining of supplies

This example shows CompactPCI Express board power management functions implemented using an
ispPAC-POWR1220AT8 device. If the CompactPCI Express board required the hot-swap function and

CompactPCI Express backplanes are similar to CompactPCI backplanes. However, the 12V supply is
also required to carry the bulk of the power in addition to +5V and 3.3V rails.
Figure 5-17. Complete CompactPCI Express Board Power Management
The difference between the CompactPCI and CompactPCI Express board power management implementation (Figure 5-17) is that in this circuit the 12V hot-swap uses a hysteretic current control mechanism.
The +5V and +3.3V hot-swap implementation is the same as the one described in “Hot-Swap Controller
with Hysteretic Current Limit Mechanism” on page 5-4. The 12V hot-swap mechanism is described in
“12V/24V Hot-Swap Controller” on page 5-8.
Programmable Features
• The secondary board power management section can be completely customized to meet board management needs.
• Power rail voltage and current can be measured through I2
C.
• 12V hot-swap behavior can be adjusted to meet the characteristics of any MOSFET.

Power Supply OR’ing Controllers
6.1 What is Power Rail OR'ing?
One method used to increase the reliability of high availability systems is through the use of
systems that are powered by two or more (redundant) power supplies. These supplies are generated either by multiple sources or the system is connected to the main supply by the use of
multiple paths. Boards connected to these redundant supplies derive a single high availability
rail through the use of diodes, as shown in Figure 6-1. This arrangement is called a power rail
OR’ing.
Figure 6-1. N-supply OR’ing Control Using Diodes
This is a simple arrangement. Only the supply that has the highest voltage drives the main
board voltage. Also, if the supply voltages are roughly equal, the load power is shared between
each source. If a supply fails, the load is transferred to other supplies automatically without any
interruption.
Although this is the simplest and most reliable way of OR’ing supplies, this circuit has a disadvantage: it wastes power. Diodes usually drop about 700mV. If the load current is, say, 2A, the
power dissipated by the diode is 1.4W. If there are ten boards in a shelf, the power dissipated is
14W, which stresses the cooling system. In addition, diodes that can dissipate more than 2W
must be used. These diodes are not only expensive but also are large, requiring more circuit
board area.

6-2 Power Supply OR’ing Controllers
To minimize the power dissipation, some designs use Schottky diodes. These diodes drop about 400mV,
resulting in approximately half the power dissipation. Nonetheless, the dissipated power is still too high,
and Schottky diodes are usually more expensive.
Modern power OR’ing circuits use MOSFETS (Figure 6-2) to reduce the power dissipation significantly.
Typical turn-on resistance of an N-channel MOSFET is about 25mΩ, so the power dissipated by this
MOSFET at 2A is 100mW (2*2*25 E-3). In other words, the power dissipation is reduced by 93%.
Figure 6-2. Power Supply OR’ing Control Using MOSFETs to Reduce Power Dissipation
6.2 Challenges of Designing a MOSFET OR’ing Circuit
When turned on, MOSFETs allow current to flow in both directions. Consequently, a voltage difference
between any two rails results in a reverse current flow into the lower voltage supply rail. For example, a
1V difference between VinA and VinB can result in 20A (1V / (0.025 +0.025)) flowing from the higher
voltage supply into a lower supply rail. This causes overloading of supplies and, in some cases, damage
to the supplies.
To prevent reverse currents, a power supply OR’ing control circuit is required. There are two methods
used for preventing the reverse current:
• Monitor current through the MOSFET and turn off the MOSFET, which has less current than the
threshold. Current dropping below the threshold can indicate reverse current build up in that limb. If the
current in all the limbs is greater than the minimum threshold, all the MOSFETs are left turned on in
order to enable load current sharing.
• Monitor the voltage difference between the rails of the input supplies and turn off the MOSFET that is
connected to the lower voltage rail. When the voltage difference between the two rails is less than a
diode voltage drop, then both MOSFETs are left on, the current to be shared.
The following section discusses positive voltage and negative voltage OR’ing circuits implemented using
Lattice Power Manager II devices.

6.3 +5v Power Supply OR’ing (Using MOSFETs) Circuit
The circuit in Figure 6-3 shows OR’ing of two 5V supply rails, 5V_a and 5V_b. The OR’ing control
algorithm is implemented in a ispPAC-POWR1014A device. The current through each limb is monitored
by the ispPAC-POWR1014A device through current sense amplifiers CSA_a and CSA_b. MOSFETs Q1
and Q2
implement the OR’ing function. The common 5V supply rail is derived by combining the drain
terminals of Q1
and Q2
. When both MOSFETs are off, their body diodes provide an inefficient OR’ing
mechanism. In Figure 6-3 the OR’d supply feeds a hot-swap controller.
Figure 6-3. An ispPAC-POWR1014A Device Implementing Two-Rail 5V OR’ing Control
The circuit starts with both MOSFETs turned off. The load is turned on by enabling the hot-swap controller. When the load starts drawing power, it automatically draws power from one of the MOSFET body
diodes. If both voltages are very close, the load pulls current from both the MOSFET body diodes, and
both are sensed by the respective current sense amplifiers.
The ispPAC-POWR1014A device turns on the MOSFET on a limb only if the current through that limb is
above a threshold value. If the current in both rails is above their thresholds, then both MOSFETs are
turned on.
The ispPAC-POWR1014A device continues to monitor the current level in both limbs. During operation,
if the current through one of the MOSFETs drops below its low current threshold (due to a sudden drop of

that power rail’s voltage), then that MOSFET is instantly turned off. When the MOSFET is turned off its
body diode blocks the reverse current. Because the MOSFET is turned off when the current drops below
the positive threshold, the reverse current that would be driven back into the power supply is avoided. In
effect, this circuit implements OR’ing of supply rails through a proactive reverse current avoidance
method.
Algorithm for Implementing OR’ing through MOSFETs
Step 1 – Wait for at least one of the rails to reach operating voltage value.
Step 2 – Enable the load or the hot-swap controller.
Step 3 – Wait for the load to turn on.
Step 4 – If the current in Limb A is greater than its turn-off threshold, turn on the MOSFET.
Step 5 – If the current in Limb B is greater than its turn-off threshold, turn on the MOSFET.
Step 6 – Wait for either of the currents in the MOSFETS that are turned on in a limb to drop below its
turn-off threshold. If the current drops below the turn-off threshold, turn it off and wait for the current to
increase above the turn-off threshold, then turn the MOSFET back on. Continue executing step 6.
Programmable Features
The following programmable features enable the design described above to meet the needs of a wide
variety of OR’ing circuits.
• Individually program thresholds of two comparators to implement hysteresis using a logic equation for
MOSFET turn on current and MOSFET turn-off current levels.
• Programmable thresholds for determining the valid input operating voltage range.
Additional Functions That Can be Integrated into the ispPAC-POWR1014A Device
• Hot-swap controller – Either soft start or hysteretic current controller.
– One of the MOSFET drivers can be freed to implement the hot-swap controller by using the transistor circuit shown in Figure 6-4 on page 6-6.
• Integrate sequencing.
• Integrate voltage supervision, reset generation and watchdog timer functions.

6.4 Power Supply OR’ing of Three or More 5V Supply Rails
Using MOSFETS
A ispPAC-POWR1014 device supports two MOSFET drive circuits; however, each MOSFET drive can
drive gates of multiple MOSFETs simultaneously. The circuit in Figure 6-4 makes use of this feature to
implement N-supply rail OR’ing through a MOSFET using one HVOUT signal from the Power Manager
II device.
The operating principle of this circuit is the same as above. The only difference here is that a four-transistor circuit is used to drive the MOSFET gate, as shown in the inset block as OR MOSFET Control.
The P1
PNP transistor is turned on to enable the voltage and current from HVOUT to the gate of the
MOSFET. P1
is turned on when N2
turns on, which is when the OUT pin of the ispPAC-POWR1014 is at
Logic 0 (N1
is off). At that time N3
is also off. To turn the OR MOSFET off, digital output is set to Logic
0. At that time N2
turns off and N3
turns on, draining the charge stored in the MOSFET gate, which turns
it off immediately.
The diode D1 is introduced in the base circuit of the N3
to delay turning on N3
compared to N1
, and to
turn the N3
off before N1
. This avoids the condition where P1
and N3
are both on at the same time, preventing turning off the other MOSFETS in the OR circuit.Power 2 You: A Guide to Power Supply Management and Control

The operating principle of the N Rail 12V OR’ing with MOSFET is the same as that of the N-Rail 5V

Operating Principle of the C-Pump Block
The HVOUT pin of the ispPAC-POWR1014A device toggles, outputting 12V for 32s and 0V for 8s.
When the HVOUT pin is at 0V, the capacitor C1
gets charged to a voltage that is highest of all 12V rails
through the diode D2. When the HVOUT pin is at 12V, this voltage is then added to the capacitor (C1
)
voltage and that turns the transistor P2
on and charges C2
through diode D3
to approximately 20V. This
voltage is then routed to the MOSFET gates through the OR MOSFET control block.
The ispPAC-POWR1014 device, like the N-rail (5V) OR’ing circuit operation, then monitors the currents
through the rails and turns on the corresponding MOSFET if its current is higher than the turn-on threshold.
Algorithm Implementing N-Channel OR’ing Through MOSFETS
Step 1 – Wait for at least one of the rails to reach operating voltage value.
Step 2 – Enable the load or the hot-swap controller.
Step 3 – Wait for the load to turn on.
Step 4 – If the current in Limb A is greater than the minimum threshold, turn on the MOSFET through the
corresponding digital control.
Step N – If the current in Limb N is greater than its minimum threshold, turn the MOSFET on.
Step N+1 – Wait for either the current through the limb, whose MOSFET is turned on, to drop below the
threshold and then turn it off, or wait for the current in the limb whose MOSFET is turned off to go above
threshold and then turn that MOSFET on. Continue executing step N+1.
(Steps N+1 is implemented using logic equations for all N-MOSFETs such that the circuit monitors and
controls all MOSFETS in parallel)

6.6 -48V Supply OR’ing Through MOSFETS
The circuit shown in Figure 6-6 monitors the voltage difference between the two -48V voltage rails using
a simple resistive voltage divider. In the following circuit there are two rails, -48VA and -48VB. Initially
the MOSFET is off and the OR’ing function is performed by the body diodes. The voltage difference
between the two rails is monitored by the resistors R1
through R4
. The values are selected such that when
the voltage difference is greater than 0.4V, a Schottky turn-on voltage, the corresponding node A_Hi or
B_Hi goes above 0.75V. The logic equation within the ispPAC-POWR607 device turns the MOSFET on
and the less negative rail is turned off, preventing reverse current. If the voltage difference between the
two rails is less than 0.4V, both MOSFETS will be turned on.
Figure 6-6. Dual -48V MOSFET OR’ing Circuit Using an ispPAC-POWR607 Device

The values of R1
, R2
, R3
and R4
are selected such that there is a dead band of 0.4V about the common -
48V rail. That is, if the -48VA and -48VB are within 0.4V of each other, both the MOSFETS are turned
on. This dead band voltage value can be changed by selecting a different potential divider setting.
Additional Functions That Can Be Integrated Into the ispPAC-POWR607 Device
One of the useful functions that can be added to the circuit shown in Figure 6-6 is monitoring of -48VA

Figure 6-7 shows the -48V voltage sensing circuit that uses two 50kΩ resistors (R1

the voltage. The voltage at the junction of R1

The second ispPAC-POWR607 device performs the hot-swap function in hot-swappable boards. The
voltage monitoring, fuse fault monitoring, MOSFET OR'ing, and hot-swap control functions can be integrated into an ispPAC-POWR1014 device. In addition, if power measurement is required, one can use an
ispPAC-POWR1014A device instead of the ispPAC-POWR1014 device and use a opamp circuit to
amplify the current through the circuit.

Power Feed Controllers
7.1 What are Power Feed Controllers?
In many systems, including base stations, microwave add-drop multiplexers and MicroTCA
shelves, a circuit board is required to feed power to an external system. In base stations, the
power is for a remote radio head; in the case of a microwave system, an external modem and an
antenna on a tower require power to be sourced from the system on the ground; and in the case
of MicroTCA, the power module is needed to feed power to multiple Advanced Mezzanine
cards plugged into the same shelf.
In most of these cases, the power feed is required to monitor for faults such as over current and
under current, as well as to provide short circuit protection. This chapter discusses -48V and
12V power feed arrangements because they are the most common. These designs can be modified to support other voltages as well.
7.2 Dual Rail -48V Supply Feed
The circuit shown in Figure 7-1 uses MOSFETs to control the power feed to two -48V rails. To
prevent damage to the MOSFETs during the power feed event, the current through the MOSFET is limited using a hysteretic current control mechanism for a fixed period. After that
period, the MOSFET is fully turned on and the circuit goes on to monitor the currents for over
current and under current faults. There are three types of current faults that can occur in power
feed circuits:
1. No current fault – If the external cable is broken
2. Over current fault- External system draws more current than normal (not dangerously high
current)
3. Short circuit current fault – Dangerously high current due to a short circuit in the power feed
cable
If a no-current or over-current fault is detected, the fault flag becomes active for that channel. If
a short circuit is detected, the MOSFET is shut down in less than 500ns. After a fault is Power 2 You: A Guide to Power Supply Management and Control
7-2 Power Feed Controllers
detected, the circuit tries continuously to restart the power feed as long as the enable signal is active for
that channel.
Figure 7-1. The ispPAC-POWR607 Device Implements a Dual-Channel -48V Power Feed Circuit
Circuit Operation
The circuit generates two channels of power, -48V_1 and -48V_2, through the MOSFETs Q1
and Q2
. The
open circuit current limit (the value below which the circuit is assumed to be open) is set by the resistors
RS
1 and RS
2. The monitoring threshold voltage of VMON1, VMON2, VMON3 and VMON4 pins of the
ispPAC-POWR607 device are set to 0.075V. The values of series resistors RS
1 and RS
2 are selected such
that at the lower current limit the voltage dropped across the RS
1 and RS
2 is 0.075V. The over current
limit is set by the resistors R1
and R2
for the power feed 1, and R3
and R4
set the over current limit for
power feed circuit 2. R1
and R2
are selected such that R1
/ (R1
+R2
) = 0.075V when maximum current is
flowing through the RS
1 resistor. In other words, Imax * RS
1 * R1
/ (R1
+R2
) = 0.075V. The values of R4
and R5
are also selected using the same equation.
When the enable signal is activated, the circuit turns on the MOSFET with the current limited to a value
determined by the programmed over current limit for a period determined by the Timer 1 for power feed
1 and Timer 2 for the circuit 2. After Timer 1 or Timer 2 expires, the corresponding MOSFET is fully
turned on and the circuit starts to monitor for over and under current. Note: The selected MOSFET should
be able to handle the maximum current for the duration determined by Timer 1.
After the MOSFET is fully turned on, if an over or under current condition is detected, the MOSFET is
turned off through the transistor N1/ N2, and Timer 3 and Timer 4 (retry timers) are started. When the
retry timer expires, the MOSFET is turned back on with an initial hysteretic control, as before.
If the circuit detects a very high current (as detected by 0.7V across the series resistors RS
1, RS
2) the
transistors N3, N4 pull down signal SC1 and SC2. These signals are connected to the digital inputs of the
ispPAC-POWR607 device. The logic equations within the ispPAC-POWR607 device shut the MOSFET

(in less than 500ns) and the retry timer is started. After the
retry timer expires, the transistor N1
, N2
that shuts down the MOSFET is turned off.
The Fault 1 and Fault 2 signals are controlled by a routine that monitors over and under current conditions in each of the circuits. When an over current fault occurs, the corresponding flag is set to high.
Along with that, the UC_OCb (under current and over current flag) will be set to logic 0. If an under current event is detected, the UC_OCb signal will be set to Logic 1. If the fault exists in both circuits 1 and
2, then the status flag toggles between the conditions once every 8ms.
Algorithm
The design is implemented using logic equations to provide independent operation on each of the channels. The following algorithm makes use of simple logic equations. There are five equations that control
the power feed for one of the circuits. All equations are active in parallel. For example, the short circuit
monitoring section is always active and shuts the MOSFET down if a short circuit occurs when any one
of the other four equations are operational. This algorithm (set of five equations) is repeated for the second channel power feed.
The fault indication flags are controlled by the algorithm implemented in the sequence controller section
of the algorithm.
1. Equation 1 circuit 1 – Waits for the enable signal to become active to begin the hysteretic controlled
power feed. The Power feed is expected to be complete within a preset period set by the hysteretic
control timer. The hysteretic control timer is also started when the enable signal gets activated and
starts the hysteretic control timer. After the initial hysteretic control timer expires, the MOSFET is
turned on fully. If a fault is detected, this equation waits for the retry timer to expire before initiating
the hysteretic power feed.
2. Equation 2 circuit 1 – Waits for a short circuit condition detection. When a short circuit is detected,
this equation turns the MOSFET off through a fast asynchronous reset signal.
3. Equation 3 circuit 1 – Monitors for over or under current conditions. When such a condition is
detected, the MOSFET is turned off and a retry timer (2 seconds) is started.
4. Equation 4 circuit 1 – Monitors for the retry signal and the enable signal to begin the 5ms hysteretic
control timer. This hysteretic control timer is used by equation 1.
5. Equation 5 circuit 1 – The fault flag is cleared to recapture the fault condition when the normal operation begins.
The fault conditions are reported by the sequence controller.
1. When the circuit 1 is operating normally and a fault has not already been reported, check on circuit 1
for over or under current fault on circuit 1 and, if a fault is detected, activate the Fault_1 output.
2. If it is an over current condition or short circuit condition, turn the UC_UCb flag off.
3. When the circuit 2 is operating normally and a fault has not already been reported, check on circuit 2
for over or under current fault on circuit 2 and, if a fault is detected, activate the Fault_2 output.Power 2 You: A Guide to Power Supply Management and Control

4. If it is an over current condition or short circuit condition, turn the UC_UCb flag off or else turn it
back on.

7.3 Three Channels of a +12V Power Feed System
In some applications, two or more channels of 12V power feed are required. For such applications, the
following three-channel power feed circuit is used. More than three channels of power feed requires multiple implementations of the following circuit. This design is modular in order to address implementations requiring less than three channels of power feed so that free resources can be used for other payload
power management functions.Power 2 You: A Guide to Power Supply Management and Control
Power Feed Controllers
Power Feed Controllers 7-5
Figure 7-2. Three-Channel 12V Power Feed Circuit
Figure 7-2 shows a ispPAC-POWR1014A device used to feed 12V to three channels. Each of the channels can be controlled independently. For each channel this circuit offers under current, over current and
short circuit current protection, along with fault indication. After the fault is detected, the circuit retries
continuously with a programmable delay between retries. The power is controlled through a MOSFET
and the circuit ensures operation of the MOSFET in its safe operating area. All voltage and current during
the operation can be measured using the on-chip ADC through I2
C.
Circuit Operation
The ispPAC-POWR1014A device derives its power from the input 12V supply. The operating principle
of the external charge pump is as follows (Figure 7-2):
The ispPAC-POWR1014A HVOUT pin toggles between 12V (for 32s) and 0V (for 8s) cyclically.
When the HVOUT1 pin is at 0V, the capacitor C1
gets charged to backplane voltage of 12V through the
diode D2
. At this time the transistor P2
is off. When the HVOUT1 toggles up to 12V, the C1
voltage is
added to the HVOUT1 pin voltage, resulting in the generation of approximately 24V at the junction of C1
and D2
. This voltage turns P2
on and charges the capacitor C2
to about 22V through the diode D3
. This
voltage is sufficient to turn on the MOSFETs Q1
through Q3
.

Once on, the device begins toggling the HVOUT1 pin to generate about 22V at the CPOUT pin and waits
for a high on any of the 3 EN signals. After receiving the En signal, the corresponding MOSFET is turned
on using the dual current level hysteretic control mechanism while monitoring for the output voltage.
When, say, the EN_1 signal is turned on, the OUT3 pin is set to logic 0. This turns off the transistor N1
,
which in turn turns on the transistor N2
. The transistor N2
provides the gate drive for the transistor P1
,
turning it on. The transistor P1
then applies 22V from the CPOUT pin to the gate of the MOSFET Q1
through a resistor, turning it on.
If a supply fault is detected, the OUT3 and the OUT4 pins are set to Logic 1. This turns off the transistor
P2
and turns on the transistor N4
. The N4
then discharges the MOSFET gate to turn it off immediately.
When power feed operation begins the MOSFET Q1
is turned on. As a result, the current through the
MOSFET starts to increase significantly. This results in the MOSFET operating outside its safe operation
area (SOA), resulting in damage to the transistor. To avoid that damage, the MOSFET is turned on with a
hysteretic current control. The following section describes the MOSFET current control operation.
Dual Current Level Hysteretic Control
Figure 7-3 shows the safe operating area for a MOSFET. This is a Log-Log graph with voltage across the
MOSFET (VDS) on the X-axis and current through the MOSFET on the Y-axis. The dotted lines represent the safe operation envelopes for different pulse width durations. When the power is applied to the
MOSFET and begins to turn on, the point of operation is at the right bottom side of the graph. The red
line indicates the current limit controlled by the hysteretic controller implemented in the ispPACPOWR1014A device. The current through the MOSFET is limited initially to the lower level. This current charges the capacitor on the load, reducing the voltage across the MOSFET. When the voltage across
the MOSFET drops to approximately its mid point (for example, 6V), the current is doubled while operating completely within the safe operation area. The first set point current and the second set point values
are determined by the safe operation area of the MOSFET as shown by the red line in Figure 7-3.

After the voltage at the load reaches the minimum operating value, the MOSFET is turned on fully. The
circuit then begins to monitor for over current and no current faults. When a fault is detected, the corresponding fault output is activated and the circuit waits for the retry delay. During the retry waiting period,
the fault indication is maintained. After the retry period, the circuit begins to restart the MOSFET current.
If the output voltage does not reach its minimum operating value within 10ms, the fault flag is turned on
and the circuit waits for another retry period.
Algorithm for Each Power Feed Channel
1. Wait for enable signal.
2. Start power feed and wait for output voltage to reach its minimum operating level within 10ms. This
step turns on the MOSFET with two current settings.
3. If the output voltage is within its safe operating level, turn the MOSFET on fully and begin monitoring
the output current for over and under current faults. If a fault is observed, flag the fault, then turn the
MOSFET off and jump to retry timer.
4. Wait for the retry timer to expire, then jump to step 1 to begin the power feed process.
5. During the four step sequence above, the following operations are performed in parallel:
– 12V Power feed control with two-step current feed.
– Monitor for short circuit current and turn the MOSFET off within 500ns when a fault is detected.
– Monitor for the enable signal and turn off the MOSFET.
Programmable Features of Power Feed
The following section outlines all the programmable features of this design:
1. Customize the design to meet any MOSFET characteristics: two current levels can be programmed. If
the design requires only one current level, the corresponding equation can be changed easily.
2. If faster turn-on times are required, the circuit can be modified to pump larger currents during start up.
These new currents can be independent of the min and max operating current limits.
3. The timer used to monitor the initial supply turn-on period is programmable. This design used 10ms. It
can be increased or decreased, depending on the design’s requirement.
4. Retry period – this design used a two second timer. It can be programmed from 32s to two seconds in
122 steps.
5. Over current and under current setting – this can be changed simply by altering the threshold of the
comparator.
Integrating Other Payload Power Management Functions into the ispPACPOWR1014A Device
This circuit uses the ispPAC-POWR1014A device to implement three channel 12V power feed functions.
Each channel uses three VMON signals, one digital input signal and four output signals. If the circuit
requires fewer power feed channels, that portion of the design can be removed and the free resources can
be used to integrate other payload power management functions, such as sequencing, monitoring and Power 2 You: A Guide to Power Supply Management and Control

watchdog timers. This design can also be exported to a ispPAC-POWR1220AT8 device to implement the
three channel power feed functions along with other payload power management functions.
Applicable Power Manager II Devices
This design used the ispPAC-POWR1014 device. However, the power feed algorithm can be integrated
into a ispPAC-POWR1220AT8 device, or an ispPAC-POWR607 device can be used to implement the
power feed algorithm for each channel.
7.4 2-Channel +12V & 3.3V Power Feed With MOSFET
OR’ing
In applications such as MicroTCA, the power module is required to implement 16 channels of 12V power
feed circuits. Each channel provides power to an Advanced Mezzanine Card (AMC) slot. When an AMC
is plugged into the back plane, the power module turns on the 3.3V to power the AMC’s management
module. The management module then communicates with a shelf manager, which then orders the power
module to turn-on 12V. In some cases, the 12V supply is turned on along with the 3.3V supply and the
circuit does not wait for an independent payload power enable signal. The power module then begins to
monitor for over current and, if an over current condition is detected, the MOSFET is turned off. During
system operation, if the AMC card is extracted the Power Module is required to turn the power off within
100s.
For reliability purposes, the 12V and 3.3V supplies are sourced from two different power module cards.
Both of these supplies are OR’d on the backplane. At any given time only one of the power modules supplies power to the backplane. The standby power module sets its voltage to a value lower than the online
module. To avoid wasting power, MOSFETs are used to provide OR’ing functionality. A detailed
description of the MicroTCA power feed standard is beyond the scope of this document.
The circuit in Figure 7-4 shows how a ispPAC-POWR1014A device can be used to implement a twochannel power feed.Power 2 You: A Guide to Power Supply Management and Control
Power Feed Controllers
Power Feed Controllers 7-9
Figure 7-4. One-Channel uTCA Power Feed Using Half of an ispPAC-POWR104A Device
Circuit Operation
Figure 7-4 shows the circuit required to implement one channel of 12V and 3.3V power feed. The 12V
power feed is controlled through two MOSFETs, the Pass device (Q1
) and the OR’ing (Q2
) device, shown
at the top right section of the circuit. The 3.3V power feed is controlled through a P-Channel MOSFET
Q3
using the transistor N3
. When the Enable# signal is active, the 3.3V supply is turned on through the
MOSFET Q3
. Subsequently, when the Payload_On signal becomes active, the 12V power is fed to the
circuit through the Pass MOSFET Q1
. The pass MOSFET Q1
is turned on using the two-current hysteretic control mechanism. Because Q1
is on the 12V rail, its gate voltage should be at about 20V when it is
turned on. The 20V gate drive is generated through the external charge pump implemented using C1
, D1
,
P2
, D2
and C2
(the circuit operation described in “Dual Current Level Hysteretic Control” on page 7-6),
to ensure that the MOSFET is operated within its SOA. Once the output power is above its minimum
operating level, Q1
is fully turned on and the OR’ing MOSFET Q2
is turned on or off depending on the
EMMC primary or redundant status. This ensures that only the primary supply wins the OR’ing arbitration. When an over current event is detected, the ispPAC-POWR1014A device shuts Q1
and Q2
down

During Operation
1. If the output supply drops below the minimum threshold (probably because the on-line supply has
failed), the standby device turns on the OR’ing MOSFET Q2
and the primary device turns the OR’ing
MOSFET off and flags the EMMC Alert signal. This ensures that the AMC does not see its 12V supply voltage dip below its operating level.
2. The current in the 12V supply is also monitored for fault. If the current exceeds the maximum operating level, the Pass MOSFET is turned off, activating the EMMC Alert signal.
3. Before the extraction of the AMC from its slot, the AMC usually sends a signal to the shelf manager.
The shelf manager then deactivates its payload power supply by disabling the Payload_On signal.
When the payload signal is turned off, the user can extract the AMC from its backplane. Subsequently,
when the AMC is extracted, the enable signal gets deactivated and the 3.3V supply feed to the AMC is
turned off within 100s. In some cases, the enable payload voltage signal does not exist. In such cases,
the design can be modified to support only Step 4.
4. In the case of an accidental AMC card extraction process, both 12V and the 3.3V supplies are turned
off at the same time within 100s from the time the enable signal becomes inactive.
ispPAC-POWR1014A (MicroTCA) Power Feed Algorithm
1. Wait for the enable signal, and when it becomes active turn the 3.3V supply on.
2. Wait for the Payload_On signal and turn 12V on. This can be modified easily to turn 12V on when the
enable signal is activated. If the 12V does not turn on within 10ms, turn 12V off and report the fault.
3. Turn OR’MOSFET on if the card is primary; otherwise, turn the OR’ing MOSFET off.
4. Start to monitor the following and take action:
a. Current – Should be lower than the over current limit. If the current is more than the over current limit, shut the Pass MOSFET off and flag the error to EMMC.
b. Output voltage – If the voltage is not higher than the lower threshold for primary, then turn the
OR’ing MOSFET off and report the error. If the payload voltage is higher than the over-voltage
limit, turn the Pass and OR’ing MOSFETs off and report the error to the EMMC.
c. If the card is configured as secondary or redundant, and if the voltage is lower than the minimum primary voltage, turn the OR’ing MOSFET on and report the error back to EMMC.
d. If the enable signal becomes inactive, turn the Pass and OR’ing MOSFETs off immediately.
e. If the primary becomes secondary during operation, turn the OR’ing MOSFET off and monitor
for lower than allowed voltage to turn the MOSFET on.
f. If the secondary becomes primary, turn the OR’ing MOSFET on and start monitoring for a
higher than allowed voltage range.Power 2 You: A Guide to Power Supply Management and Control

• The voltage and current values can be measured through I2

• Not all MicroTCA implementations use all of the features specified in the standard. In such cases, one
can keep the OR’ing MOSFET off when the current is below a lower threshold limit. This protects
against reverse current flow from the secondary when its voltage is higher than the primary.

Margining and Trimming
8.1 What is Voltage Margining?
Margining is a test step that ensures a board is operational across the input variable range. A
voltage margining test ensures that the board is functional across the operating range of its
onboard and input supplies. Circuit boards are also subject to other margining tests such as
temperature, timing and noise.
For example, if the allowed tolerance of input supply is ±10%, the voltage margining test
ensures that the board is functional when the input supply is at its margin-high (nominal voltage + 10%) value and when its supply is at margin-low (nominal voltage -10%) value. If the
board has a number of board-mounted supplies, then the margining test should also cover the
variation of individual board-mounted supplies.
Semiconductor devices typically operate slowest when their operating temperature is at its
highest value and applied voltages are at their lowest. Similarly, these devices are fastest when
the operating temperature is at its lowest and the voltages are at their highest. To ensure that the
design is stable across temperature and voltage, designers subject their circuit boards to high
temperature in an environmental chamber with the operating voltages dialed down, and then
check the operation at colder temperatures with their voltages dialed up. This is called 4-corner
testing.
Margining tests typically are conducted during board debug. In some cases, Quality and Reliability departments will require margining before they will approve manufactured boards.
8.2 Voltage Margining Implementation
Figure 8-1 shows a DC-DC converter with a resistor connected to its Trim/ Feedback Node.
The value of this resistor typically determines the nominal output voltage value of the DC-DC
converter.Power 2 You: A Guide to Power Supply Management and Control
8-2 Margining and Trimming
Figure 8-1. Supplies are Margined by Changing the Resistor Connected to the Trim/FB Node
DC-DC converters usually require standard resistor values to set their output voltage to a standard value –
e.g., 3.3V, 2.5V, 1.5V. To change the output voltage by ±5% of their nominal operating voltage, designers
use either a potentiometer for each of the DC-DC converters or a series parallel combination of standard
resistor values. One has to manually implement the resistor change to all the boards that will be subject to
testing in an environmental chamber.
Some disadvantages of manually altering resistor values for margining:
• Increased Delay - finding resistor values that accurately alter the output voltage often require a series
and/or parallel combination of standard resistors that must be manually soldered. Different resistor
combinations for each of the supplies must be found. Sometimes the board failures in the environmental chamber could be due to bad solder joints caused by manual soldering. Even if a potentiometer is
used, the moisture in the environmental chamber creates contact problems that delay the margin test.
• Manually soldering a resistor for margining cannot be used for automated reliability testing.
• Due to accuracy requirements, manual methods cannot be used for margining the low core supply voltages of modern VLSIs and CPUs.
8.3 What is Trimming?
Modern circuit boards require multiple DC-DC converters with low voltages (1.2V or less) with high current capacity. A specification of 10A to 20A at such low voltages is not uncommon. In addition, ICs
require very tight output voltage regulation of approximately 1.5% or less to ensure that there is enough
headroom to meet the dynamic current requirements of the CPU/ASIC without violating the input voltage
specs.
Trimming is the process of accurately setting and maintaining the output voltage of a DC-DC converter
close to a pre-determined value across voltage and temperature. Margining is a special case of trimming.
Trimming also uses the same mechanism shown in Figure 8-1 to set a given voltage. However, to meet
accuracy requirements of 1.5% or better, DC-DC converters use very high accuracy (0.1% or better) trim
resistors to set the output voltage. In some cases, laser trimmed resistors and compensating resistors are
used to allow for converter to converter output voltage accuracy differences.
As can be seen, when the DC-DC converter is required to meet high accuracy demands, cost increases
significantly. In some cases, digital power converters are used to meet these high power and high current
demands. These DC-DC converters are more expensive, as they require ADCs, DACs and accurate voltage references.

Margining and Trimming
Margining and Trimming 8-3
Typical Applications That Require Power Supply Trimming
Trimming is required for circuit boards using ICs that require low supply voltages (1.2V or lower) with
high current ratings (5A or more).
For example, a 1.2V DC-DC converter should guarantee a maximum of ±5% (±60mV) variation under all
of the following conditions:
• No-load to full-load average current variation
• Output voltage ripple
• Dynamic power demands by the IC during different average current levels
• Component tolerances during manufacturing
In general, to meet the voltage device spec under all of the above conditions safely, the DC-DC converter
requires an initial operating voltage accuracy of 2% or better. These high accuracy, low voltage supplies
are usually more expensive and require high precision resistors to set the voltage.
Alternatively, the accuracy of a conventional lower cost DC-DC converter can be improved by using an
external trimming mechanism. The next section describes trimming using the Lattice Power Manager II

8.4 Trimming and Margining – Principle of Operation
Figure 8-2 below shows a Lattice Power Manager II device implementing trimming and margining functions for an analog DC-DC converter.
Figure 8-2. Supplies are Margined by Changing the Resistor Connected to the Trim/FB Node
On the top portion of Figure 8-2 is a DC-DC converter supplying power to its load. The output voltage is
determined by the components used in its feedback circuitry. The Power Manager II device at the bottom
measures the voltage using the on-chip ADC though differential sense inputs. The Power Manager II can
increase or decrease the output voltage of the DC-DC converter by increasing or decreasing the voltage
or current applied to the DC-DC converter’s feedback node, using its on-chip DAC. For some DC-DC
converters, increasing the feedback node current or voltage reduces its output voltage.

8-4 Margining and Trimming
A set point register in the Power Manager II holds the required voltage value at the load. Once every
580s the Power Manager II device measures the voltage at the load using its on-chip ADC. The digital
output of the ADC is compared against the set-point register contents. If the load voltage is higher, the
DAC contents are decremented, which in turn reduces the voltage applied to the feedback node of the
DC-DC converter. If the load voltage is lower, the DAC contents are incremented, applying higher voltage to the node. This is called the closed loop trim mechanism.
It is possible to break the closed loop trim and load the DAC register directly through the I2
C bus. This
method is used to implement margining. An external microprocessor directly loads a pre-selected DAC
value into the Power Manager II, which will result in changing the output voltage by, for example, ±5%.
The microprocessor can also measure the output voltage of the DC-DC converter using the Power Manager II’s ADC, and tweak the output voltage up and down as needed to implement closed loop margining.
In a circuit board, there typically are multiple types of supplies providing different supply voltages. These
individual supplies require different current levels to be injected into their feedback nodes. This in turn
requires a unique resistor network for each type of DC-DC converter to be connected between the Power
Manager II and the DC-DC converter feedback node.
The next section briefly describes the Power Manager II’s architecture blocks and then explains the
details of designing a resistor network connected between the DC-DC converter feedback node and the
Power Manager II DAC output.
Power Manager II TrimCell Architecture
The DAC in Figure 8-2 stores the DAC codes for nominal output voltage, as well as for margining up and
down. For example, to support margining (for example ±5%) and trimming of a low voltage set-point (for
example 1.2V 10mV), the three individual DAC values must be stored in different DAC registers. The
Power Manager II device supports six registers for each DAC. The block that includes the DAC and its
associated registers is called a TrimCell. Figure 8-3 is a TrimCell block diagram.Power 2 You: A Guide to Power Supply Management and Control
Margining and Trimming
Margining and Trimming 8-5
Figure 8-3. TrimCell Architecture in a Power Manager II Device
Six DAC registers are divided into four hardware addressable groups called Voltage Profiles. Of these six
DAC codes, four are stored in on-chip EEPROM memory. The two remaining registers are volatile. One
of the volatile registers can be loaded directly via the I2
C interface. The second register is controlled by
the closed loop trim circuit. Voltage Profiles 3, 2 and 1, when selected by either the external hardware
pins or internally by the PLD, load the corresponding codes stored in the EEPROM memory into the
DAC. With this feature one can margin each supply high or low using the on-chip PLD, or through the
hardware pins of the Power Manager II device. While operating in these profiles, the Power Manager II is
said to be operating in an open-loop; that is, the DAC register contents are static and are not adjusted during operation, depending on the actual DC-DC converter output voltage.
To support the controlling of output voltage to a very high degree of accuracy (Set-point voltage ±10mV),
the Profile 0 should be used. There are three modes of operation in Profile 0:
1. Open Loop operation with the DAC code stored in the E2
CMOS®
configuration memory. Operation in
this mode is similar to that of the profiles 1, 2 and 3.
2. Open Loop/ External Closed Loop operation – Load the I2
C DAC register via the I2
C bus. This mode
of operation is used by an external microcontroller to fine tune the output voltage, depending on the
DC-DC converter’s actual output voltage. This is called an external closed loop mode of operation.
3. Closed Loop Trim – This mode of operation is used to trim a given DC-DC converter output voltage
accurately. Tight control of the output voltage is maintained by the on-chip closed loop control circuitry. Closed loop circuitry gets activated once every 580s. It can also be programmed to be activated at a slower rate: 1.15ms, 9.2ms or 18.5ms. When activated, the on-chip closed loop control
circuitry measures the DC-DC converter output voltage and compares it to the value stored in the set
point register. Depending on the DC-DC converter’s output voltage excursion, the closed loop circuitry increments or decrements the DAC contents in a way that counters the output voltage excursion

Figure 8-4.
Power Manager II Integrates Multiple TrimCells
The ispPAC-POWR1220AT8 device supports eight TrimCells in its TrimBlock, as shown in Figure 8-4.
Each of the TrimCells can be programmed independently to control a DC-DC converter. The Voltage profile selection is common to all TrimCells and is controlled by either the hardware control pins (VPS [0:1])
or through the on-chip PLD.
Figure 8-4. The ispPAC-POWR1220AT8 Device Provides Eight TrimCells in its Trim Block
When the Voltage proPOWR file is set to, for example, 3 in Figure 8-4 shown above, the DC-DC1 converter outputs 0.95V (5% below the normal operating voltage of 1V), while the DC-DC 2 converter outputs 1.14V (5% below the 1.2V nominal), and so on.
When the voltage profile is set to, for example, 1, the DC-DC1 converter outputs 1V+5%. The DC-DC2
converter outputs 1.2V + 5%. This method is used to implement margining.

When VPS [0:1] = 0 the DC-DC 1 converter outputs 1V and the DC-DC2 converter outputs 1.2V. However, TrimCell 0 maintains the DC-DC converter output voltage using the on-chip closed loop control
mechanism, while TrimCell1 uses an external microcontroller to maintain the voltage at 1.2V.
Closed Loop Trim - Mode Operation of TrimCell
Figure 8-5 shows the connection between the TrimCell and the DC-DC converter when configured to
operate in closed loop trim mode. The resistor between the Trim pin and the DC-DC converter Trim_in
pin converts the voltage applied by the DAC into a current added to the Trim summing node of the DCDC converter. The ADC is used to measure the DC-DC converter voltage. The three-state comparator
compares the ADC measured value with the set-point and the output increments, decrements or holds the
content of the closed loop trim register as is.
Figure 8-5. The ispPAC-POWR1220AT8 Device Closed Loop Trimming Mechanism
When the Power Manager II device is powered on, the DAC output voltage starts at the bi-polar zero
value. The bipolar zero voltage is determined by its offset voltage setting 0.6V, 0.8V, 1V and 1.25V. This
results in starting the DC-DC converter output voltage very close to its nominal value. Using this value,
all supplies are sequenced. Once the supply sequencing is complete, the closed loop trimming process is
activated.
The closed loop trimming circuitry operates on each of the TrimCells in a cycle. The closed loop trimming cycle can be activated using a programmable timer and can be set to 580s, 1.15ms, 9.2ms or
18.5ms. The closed loop trim circuitry consists of the ADC, three state comparator, set point register,
channel polarity controller, the control loop register increment/ decrement control and the DAC. During a
trim cycle, the closed loop trim circuitry performs the following functions for each of the TrimCells:
1. Measures the voltage of the DC-DC converter differentially through the ADC.
2. Compares the output of the ADC with the set point register. If the polarity is set as positive, the following are the effects of the comparison:
a. If the DC-DC converter voltage is higher than set point, decrement the contents of the closed loop
trim register.

8-8 Margining and Trimming
b. If the DC-DC converter voltage value is less than the set point register value, the closed loop trim
register contents are incremented.
c. If the ADC value is the same as that of the set point register, maintain the closed loop trim register
value.
If the polarity set is negative, the incrementing and decrementing register in steps a. and b. above are
reversed.
Closed loop trimming ensures that the voltage at the load is accurate within ±10mV from the set-point
value This error includes the maximum ADC measurement steady state error and the DAC quantization
error. According to the datasheet, the maximum ADC error (including its gain, offset, INL and DNL
across process, voltage and temperature) is 8mV.
The error from the DAC is due to its step size. This error is calculated as follows:
Usually the resistors between the DAC and the DC-DC converters are calculated such that the full scale
(128) swing of DAC results in swinging the output voltage of the DC-DC converter by 5%. This means
that each step of the DAC code results in an output voltage step of 5% / 128 ~ 0.05%. For a 3.3V supply,
the voltage variation due to a single step of DAC code results in changing the output voltage by
3.3*0.05/100*128 = 130V (approximately). In effect the major error component is the ADC error.
Errors due to DC-DC converter components, DC-DC converter accuracy, etc. are compensated for by the
closed loop trim mechanism, which maintains the output voltage accurately.
Closed Loop Trim and Closed Loop Margining Using a Microcontroller
Figure 8-6 shows the configuration used for closed loop trimming with a microcontroller. Here the microcontroller measures the DC-DC converter output voltage periodically, using the on-chip ADC through the
I
2
C bus. The microcontroller then algorithmically calculates the new DAC value depending on the DCDC converter voltage and loads the new DAC code through the I2
C interface.
The microcontroller-based margining is implemented entirely through the I2
C bus and uses profile 0 in
the Power Manager II. To implement closed loop margining, the microcontroller loads the starting DAC
code into the DAC register via I2
C and waits for the ADC voltage to stabilize. Depending on the stabilized voltage value, the microcontroller increments or decrements the DAC code. This method enables
setting and controlling the margined voltage accurately.Power 2 You: A Guide to Power Supply Management and Control
Margining and Trimming
Margining and Trimming 8-9
Figure 8-6. Closed Loop Trimming and Margining Using a Microcontroller
Interfacing Power Manager II with a DC-DC converter
Interfacing a DC-DC converter with the DAC requires that the DC-DC converter output voltage is at its
nominal value when the DAC register value is at its bipolar-zero voltage in Profile 0. It also requires that
the DAC maximum or minimum code results in swinging the DC-DC converter voltage to its margin
voltage value through appropriate current injection into the feedback node.
The resistor values also should take into consideration the type of feedback node arrangements used in
DC-DC converters, their internal reference type (current/ voltage), and type of feedback. To map all types
of DC-DC converter variables to the DAC output voltage swing, a number of resistor network topologies,
shown in Figure 8-7 through Figure 8-11 are required.
Figure 8-7 shows a typical resistor network between a Power Manager II device and a DC-DC converter.
As discussed earlier, the ispPAC-POWR1220AT8 device can monitor and trim up to eight DC-DC converters individually. The trim circuit of the Power Manager interfaces to different types of DC-DC converters through a resistor network, as shown in Figure 8-7.
The resistors R1
and , R2
and R3
determine the starting voltage of the DC-DC converter. This is equivalent to connecting a resistor to ground from the trim pin. The values of these resistors are selected such
that the voltage at the node between R1
and R3
, is equal to the DAC voltage at power up.
The values of these three resistors are calculated by the PAC-Designer software using the following
inputs:
1. Type of DC-DC Converter. There are four types of DC-DC converters:
a. Fixed voltage
b. Output voltage programmable through a resistor to ground connected to its trim input

Designing Trimming and Margining Networks using PAC-Designer Software
Determining the required resistor topology involves finding a solution for a number of nodal equations
and an understanding of the error amplifier architecture of the DC-DC converter. In addition, the design
can be iterated until the solution yields standard resistor values.
The PAC-Designer software automates the process of determining the resistor topology while using standard resistors in the resistor network. Calculating the resistor values shown in Figure 8-7 through
Figure 8-11 using the PAC-Designer software is a two-step process:
1. Create a DC-DC Converter Library using the DC-DC converter’s feedback and trim section characteristics – This uses a few parameters commonly specified in a DC-DC converter datasheet.
2. Associate a DC-DC converter to a TrimCell and calculate the resistors for a given output trim and
margin voltage specification for that DC-DC converter.

to GND or to VOUT
b. DC-DC Converter with Programmable Output Voltage – The output voltage of these DC-DC

down by 5-10%.

is open. This is its normal operating state.
Next, there are two fields under the headings “Example 1 R to GND”, “Example 2 R to GND” and
“Example 3 R to Vout.” Examples 1 and 2 are conditions used to generate a margin voltage that is different than the nominal voltage. Different target voltages will require different resistor values. These values
are provided in the DC-DC converter datasheet, usually in a table format. Some datasheets provide a formula to calculate these resistors. Enter the values of the target output voltage and the values of the target

The third column requires the value of the resistor to be connected between the trim pin and the Vout pin

EIA resistor standard – limits the resistor selection to EIA 12, EIA24, EIA48, EIA96, EIA192. It also
provides a method to calculate the exact resistor values. The selection of this option depends on design
requirements
Maximum DAC code range – used to provide additional headroom in the DAC code for maximum voltage variation. This is to account for the errors in resistor values and the DC-DC converter inaccuracies.
Maximum supply adjustment range – this is the maximum margin voltage range with respect to the
nominal value that is specified on profile 0. If the design requires margining of 10%, this value is set to
10%.
Attenuation crossover voltage – the maximum input voltage for the ADC is 2.048V. If this ADC is used
for measuring voltage higher than the Attenuation Crossover Voltage, the on-chip 1:3 attenuator should
be turned on. This allows the maximum voltage input to the ADC to increase to 6.144V. This entry sets
the voltage at which the attenuator should be switched on.

as an open circuit - The trim and margin routine calculates up to three resistors and the associated topology as shown in Figure 8-7, Figure 8-8, Figure 8-9, Figure 8-10 and Figure 8-11. This field can be used
to force the algorithm to minimize the number of resistors to the equivalent circuit shown by Figure 8-11.
To do that, first calculate the resistors using the default values. Change the Open External Resistor(s)
Threshold field to a value slightly higher than the series resistor value and click on the button. The
software automatically calculates the new resistors and the associated DAC values.
Vbpz Selection – usually it is best left as auto. In some cases, by forcing the Vbpz values to one of the
other voltages (0.6V, 0.8V, 1V or 1.25V), the number of resistors can be reduced.Power 2 You: A Guide to Power Supply Management and Control

Design Tools for Power Manager II
9.1 PAC-Designer: Power Management Design Tool
One major reason for the popularity among system engineers of programmable devices like the
Power Manager II family is the flexibility of the hardware solution. One silicon device can serve
in a variety of applications or integrate multiple board power management functions. While the
term “programmable” usually conjures images of a software engineer writing ‘C’ or assembly
language for an embedded microcontroller, programmable devices like the Power Manager II are
designed using a class of Electronic Design Automation (EDA) software that is easy to learn for
a hardware engineer with expertise in the analog, system or digital electronics disciplines. Rather
than a software engineer writing firmware, the hardware designer will model the design using a
hardware design language (HDL) or graphical tools like a schematic or waveform editor.
To make designing with the Power Manager II device as easy as possible for the engineer with a
power circuit design background, Lattice provides a free EDA tool called PAC-Designer*. In the
PAC-Designer tool, circuit designs are entered graphically and then verified, all within the software environment. In the example below, the PAC-Designer schematic window provides access
to all configurable elements of an ispPAC-POWR1014A device via its graphical user interface.
All analog input and output pins are represented. Static or non-configurable pins such as power,
ground and the serial digital interface are omitted for clarity. Any element in the schematic window can be accessed via mouse operations as well as menu commands. When completed, configurations can be saved, simulated and downloaded to devices.
Programmable hardware with a software design tool provides a more flexible solution for engineering and a cost-cutting measure for component procurement departments. Programmability is
attractive from an economic standpoint to component engineers and procurement personnel who
wish to reduce the number of discrete solutions and vendors that they must qualify, inventory,
and manage. It’s for these economic benefits that procurement departments will heavily influence the preferred part inventory of electronic components.
This chapter describes how PAC-Designer software and development kits are applied to solve
the power management and control scenarios described in earlier chapters of Power 2 You.
* This document refers to PAC-Designer version 5.3 or later.Power 2 You: A Guide to Power Supply Management and Control
9-2 Design Tools for Power Manager
Benefits of Software-Driven Programmable Hardware Design
Power management and control solutions traditionally have been implemented with discrete analog and
mixed-signal ICs. Browse the component catalog of any popular vendor of voltage supervisor or watchdog timer ICs and you’ll quickly see the hundreds of variations available to satisfy a range of accuracy,
operating conditions and capacity. Further, depending on the degree of functional integration required,
even more product variations are available. The Power Manager II technology is disruptive due to it’s
versatility, enabled through programmability. In the same way the TTL discrete logic ICs of the 1970s
have been almost entirely integrated by modern CPLDs and FPGAs, Power Manager II integrates multiple discrete analog ICs and is flexible enough to be applied across most power management configurations.
Benefits of software-driven programmable hardware design include:
• Reduce cost by reducing the number of Power Manager II components – Multiple power management
functions can be integrated into a single power management device. The integrated solution can also be
customized to meet board-specific sense and control interface requirements.
• Reduced risk of board re-spins and faster time to market – New designs or changing board requirements can be handled by an updated program for the Power Manager II. HDL-based designs are flexible to meet changing functional requirements.
• Increased likelihood of first-time success and reduced time to market - Functions and performance can
be modeled by a software program and the model can be tested fully using simulation methods
Advantages of Power Manager II over Microcontroller Firmware-Based Solutions
One of the alternative approaches to a flexible power management solution is a microcontroller with
firmware. Some of the major drawbacks of this approach are:
• Reduced reliability due to slow response to power faults: Power monitoring is controlled by hardwaregenerated interrupts, which occur once in 5 to 10ms. This determines the response time of the power
management function, which is too slow to prevent faults such as Flash memory corruption.
• Increased time to market due to limited fault coverage of the power management algorithm: A major
advantage of HDL-based designs over firmware-based designs is that the HDL-based designs can be
simulated fully on a computer rather than a testing circuit board with limited fault coverage. The types
of faults that can be created on a circuit board are limited because of secondary fault conditions due to
other components on the circuit board that can interfere with the power management algorithm.
• As a result, any changes to software require extensive board-level regression tests that are costly and
time consuming. Consequently, changes to firmware are avoided, reducing its flexibility.Power 2 You: A Guide to Power Supply Management and Control

9.2 PAC-Designer Overview
Table 9-1 provides an overview of the major features of PAC-Designer software.
Selecting the Power Manager II Device from a Design Specification
The first step in a power management and control design is to determine how many functions can be integrated into a Power Manager II device. Here are some of the key considerations (Refer to Figure 9-
1“PAC-Designer Software - ispPAC-POWR1014A” on page 9-7 for a brief description of these functions):
• Primary Power Management
– Hot-swap, redundant power feed management, external power feed
– Input voltage – Positive/ negative, need for isolation
• Secondary power management functions
– Main secondary rail(s)
– Number of DC/DC converters that will be sequenced, supervised.
– Number of DC/DC converters that will be margined/trimmed
Table 9-1. Design Tools Overview
Design Entry Tools Purpose
Power Manager II Schematic Navigate and access the configuration of Power Manager II functional blocks such as:
• Digital I/O buffer configuration
• Analog input comparators
• High-voltage output drivers
• Timer/oscillator settings
• Margin and trim cell settings
• Sequence control and supervisory logic
LogiBuilder LogiBuilder is used to design the embedded digital functions of the
Power Manager II. Logic can be captured as a sequence of events
described in a high-level state machine like language or as traditional Boolean equations.
LogiBuilder provides a Sequence Controller window that allows
you to create control sequences and define logic functions and a
Supervisory Equation window to enter combinatorial or registered
logic independent of sequence controller logic.
DC-DC Library Builder The Library Builder is used to define the voltage adjustment characteristics of DC-DC converters and voltage regulators. A detailed
description of trimming and margining software GUI is provided in
the ‘Margining and Trimming,’ Chapter 7.
Simulation Tools Purpose
HDL Export The HDL writer included with PAC-Designer exports an industry
standard Verilog HDL or VHDL model of the digital logic and
timer/counter of the Power Manager II design. HDL models can be
executed with any popular third party simulator such as Aldec’s
Active-HDL program.
Waveform Editor The Waveform Editor is a graphical application used to create and
edit waveforms for logic stimulus. Each waveform is given a userdefined name, and then edited to show transitions. The stimulus is
applied to the LogiBuilder - generated model and waveform results
are produced much like those of a traditional logic analyzer.
Lattice Logic Simulator PAC-Designer includes a logic simulator to verify logic produced
by the LogiBuilder tool.Power 2 You: A Guide to Power Supply Management and Control

The next step is to identify the smallest Power Manager II device using the number of secondary power
supply rails as well as the functions in Table 9-3.
Power Manager II Design Example
The example considered in this section is a PCI-Express add-on card application. This example is used to
describe the procedure for integrating the power management design into a Power Manager II device.
The first step is to collect the power management design specifications for the PCI Express add-on card.
Table 9-4 summarizes the power management functions implemented in a PCI-Express add-on card:
Table 9-2 shows that these functions can be integrated into a ispPAC-POWR1014A or a ispPACPOWR1220AT8 device. However, using Table 9-3, the smallest Power Manager II device that can integrate all these functions is an ispPAC-POWR1014A. The next step is to start designing the Power Management algorithm using the information given in earlier chapters.

Double click on the sequence control block of the main schematic to open the LogiBuilder screen, as
shown in Figure 9-8.
To facilitate understanding of the PCI-Express add-on card algorithm, the next section explains the LogiBuilder screen sections.
The LogiBuilder screen is divided into three sections:
The sequential execution sections – Enter a list of instructions listed in Table 9-5 to implement the
sequential execution part of the algorithm.
The exception conditions section – Enables a set of Boolean expressions which, when they become true,
interrupt the sequential execution flow. These exception conditions can only interrupt the steps which are
marked as interruptible. All other steps are not affected by the exception conditions.
The supervisory logic section – Enables the Boolean expressions direct control of some of the outputs
that are not controlled by the sequential execution portion of the algorithm.
The Boolean expressions in the exception condition as well as supervisory logic section operate in parallel to the instructions executed in the sequential execution section.Power 2 You: A Guide to Power Supply Management and Control
9-14 Design Tools for Power Manager
In the sequential execution section each step is divided into five columns:
• Step – This indicates the step number of a given instruction. This step number is used to branch to a
given step from a different location.
• Sequencer instruction – This is the instruction that is being executed by that step. Each step can take
one to several clock cycles. For example, a start timer instruction takes one clock cycle. A wait for
timer instruction stays in that step until the timer expires.
• Outputs – This lists all the outputs whose output values are changed at that step. The output state
changes after the first clock pulse while in that step.
• Interruptible – This flag enables the exception condition to interrupt the flow of execution. If the
interruptible flag is set to ‘no,’ the exception condition cannot alter the flow at that step.
• Comment – This column is used to enter the comment for that instruction.
Sequencer Instructions
There are six types of instructions used to implement the sequential execution portion of the power management algorithm. These instructions are listed in Table 9-5.
Table 9-5. Sequencer Instructions and Description

Exception conditions section
Each of the exception condition is divided into five columns:
Exception ID – The number of the exception condition: used by the compiler to point errors in that line
Boolean expression – this is the Boolean expression which, when it becomes true, will force the
sequence execution to jump to the step indicated by the exception handler step.
Outputs – Forces the outputs to the value set by the exception condition. Setting or resetting an output
results in the Boolean expression always controlling that output, and is independent of the sequence
instruction execution
Exception handler – This is the step number in the sequential execution section to which the control
jumps when the exception condition becomes true and the sequential execution section is executing a step
that has been flagged as an interruptible step.
Comments – This section is used for providing useful comments about that exception condition.
Supervisory equation section
The supervisory equation window is used to control outputs that are not controlled by the sequential execution section. The supervisory equation is divided into four columns.
Equation – This field indicates the supervisory equation number and is used by the compiler to flag
errors.
Supervisory Logic Equation – this column is where the Boolean logic condition and the associated output that is controlled by the equation is specified.
Macrocell Configuration – This column indicates the type of assignment in the supervisory logic equation for that output. It can be combinational, D-type, T-type, Asynchronous Reset or Asynchronous Preset.
Comment – provides additional information about the step for better understanding of that equation.

Figure 9-8 shows the implementation of the PCI-Express add-on card algorithm implemented using the
instructions shown above.
Start/ Stop Timer
Start Timer Selected Timer
Starts a given timer, does NOT wait for it to expire but simply
jumps to the next sequential step. The timer is reset in the prior
step. Instruction used along with the if-then-else with Timer
instruction.
Stop Timer Selected Timer Reset the selected timer.
NOP None None
No action taken during that step. Usually used in conjunction
with the wait for timer or start timer instructions. This enables the
code to jump to those instructions.

3. Turn-off 12V MOSFET when over current condition is detected.
The programmable features, shown below, of this design can be used to adapt the design across different
PCI-express add-on card configurations.
• SOA and over current levels.
• Customize the design to suit most MOSFETs.
• Initial contact de-bounce period programmable from 32s to 2 seconds.
• Short circuit timeout during start up programmable from 32s to 2 seconds.
• Reset pulse can be stretch duration programmable from 32s to 2 seconds.
• Each of the voltage monitoring thresholds are programmable from 0.67V to 5.8V.
This algorithm can be imported easily into an ispPAC-POWR1220AT8 device if the number of supplies
in the PCI-Express add-on card increases beyond five or other control functions need to be added.
10. Compiling the Design
After the design is entered, the next step is to compile the program. To compile the program click on
Tools> Compile the LogiBuilder Design
The program converts the code into ABEL (Advanced Boolean Expression Language) language and
compiles the ABEL language into a highly optimized equations netlist. These equations are then sent to
the Fitter program that fits the design into the CPLD of the Power Manager II.
11. Simulating Control and Supervisory Logic
When the primary supply rails for a circuit board are energized how will the Power Manager II respond
and sequence the various DC-DC converters and distribute the reset signals? If the firmware of a microcontroller hangs and fails to reset the watchdog timers you have defined, will the WDT assert an interrupt
the way you expect? These are the types of scenarios you’d like to model before you commit your design Power 2 You: A Guide to Power Supply Management and Control

to hardware. To help, PAC-Designer software can extract a model of your digital and timer logic to any
popular HDL simulator.
From PAC-Designer, the optimized equations produced by LogiBuilder can also be exported into VHDL
or VerilogHDL languages. These files can then be used for simulation. To export an HDL file, choose
File > Export. The Export dialog, shown in Figure 9-9, appears. From the Export What list, choose
VHDL File or Verilog File.

Description
The GAL20V8C, at 5ns maximum propagation delay time, combines a high performance CMOS process with Electrically Erasable (E2
) floating gate technology to provide the highest speed
performance available in the PLD market. High speed erase times
(<100ms) allow the devices to be reprogrammed quickly and efficiently.
The generic architecture provides maximum design flexibility by
allowing the Output Logic Macrocell (OLMC) to be configured by
the user. An important subset of the many architecture configurations possible with the GAL20V8 are the PAL architectures listed
in the table of the macrocell description section. GAL20V8 devices
are capable of emulating any of these PAL architectures with full
function/fuse map/parametric compatibility.
Unique test circuitry and reprogrammable cells allow complete AC,
DC, and functional testing during manufacture. As a result, Lattice
Semiconductor delivers 100% field programmability and functionality of all GAL products. In addition, 100 erase/write cycles and
data retention in excess of 20 years are specified.

Specifications GAL20V8
The following discussion pertains to configuring the output logic
macrocell. It should be noted that actual implementation is accomplished by development software/hardware and is completely transparent to the user.
There are three global OLMC configuration modes possible:
simple, complex, and registered. Details of each of these modes
is illustrated in the following pages. Two global bits, SYN and AC0,
control the mode configuration for all macrocells. The XOR bit of
each macrocell controls the polarity of the output in any of the three
modes, while the AC1 bit of each of the macrocells controls the input/output configuration. These two global and 16 individual architecture bits define all possible configurations in a GAL20V8 . The
information given on these architecture bits is only to give a better understanding of the device. Compiler software will transparently set these architecture bits from the pin definitions, so the user
should not need to directly manipulate these architecture bits.
The following is a list of the PAL architectures that the GAL20V8
can emulate. It also shows the OLMC mode under which the
devices emulate the PAL architecture.
Software compilers support the three different global OLMC modes
as different device types. These device types are listed in the table
below. Most compilers have the ability to automatically select the
device type, generally based on the register usage and output
enable (OE) usage. Register usage on the device forces the software to choose the registered mode. All combinatorial outputs with
OE controlled by the product term will force the software to choose
the complex mode. The software will choose the simple mode only
when all outputs are dedicated combinatorial without OE control.
The different device types listed in the table can be used to override
the automatic device selection by the software. For further details,
refer to the compiler software manuals.
When using compiler software to configure the device, the user
must pay special attention to the following restrictions in each mode.
In registered mode pin 1 and pin 13 (DIP pinout) are permanently
configured as clock and output enable, respectively. These pins
cannot be configured as dedicated inputs in the registered mode.
In complex mode pin 1 and pin 13 become dedicated inputs and
use the feedback paths of pin 22 and pin 15 respectively. Because
of this feedback path usage, pin 22 and pin 15 do not have the
feedback option in this mode.
In simple mode all feedback paths of the output pins are routed
via the adjacent pins. In doing so, the two inner most pins ( pins
18 and 19) will not have the feedback option as these pins are
always configured as dedicated combinatorial output.

In the Registered mode, macrocells are configured as dedicated
registered outputs or as I/O functions.
Architecture configurations available in this mode are similar to the
common 20R8 and 20RP4 devices with various permutations of
polarity, I/O and register placement.
All registered macrocells share common clock and output enable
control pins. Any macrocell can be configured as registered or I/
O. Up to eight registers or up to eight I/Os are possible in this mode.
Dedicated input or output functions can be implemented as subsets of the I/O function.
Registered outputs have eight product terms per output. I/Os have
seven product terms per output.
The JEDEC fuse numbers, including the User Electronic Signature
(UES) fuses and the Product Term Disable (PTD) fuses, are shown
on the logic diagram on the following page.

In the Complex mode, macrocells are configured as output only or
I/O functions.
Architecture configurations available in this mode are similar to the
common 20L8 and 20P8 devices with programmable polarity in
each macrocell.
Up to six I/Os are possible in this mode. Dedicated inputs or outputs
can be implemented as subsets of the I/O function. The two outer
most macrocells (pins 15 & 22) do not have input capability. Designs requiring eight I/Os can be implemented in the Registered
mode.
All macrocells have seven product terms per output. One product
term is used for programmable output enable control. Pins 1 and
13 are always available as data inputs into the AND array.
The JEDEC fuse numbers including the UES fuses and PTD fuses
are shown on the logic diagram on the following page.
Note: The development software configures all of the architecture control bits and checks for proper pin usage automatically.

fmax with Internal Feedback 1/(tsu+tcf)
Note: tcf is a calculated value, derived by subtracting tsu from
the period of fmax w/internal feedback (tcf = 1/fmax - tsu). The
value of tcf is used primarily when calculating the delay from
clocking a register to a combinatorial output (through registered
feedback), as shown above. For example, the timing from clock
to a combinatorial output is equal to tcf + tpd.
fmax with No Feedback
Note:fmax with no feedback may be less than 1/(twh + twl). This
is to allow for a clock duty cycle of other than 50%.

Electronic Signature
An electronic signature is provided in every GAL20V8 device. It
contains 64 bits of reprogrammable memory that can contain user
defined data. Some uses include user ID codes, revision numbers,
or inventory control. The signature data is always available to the
user independent of the state of the security cell.
NOTE: The electronic signature is included in checksum calculations. Changing the electronic signature will alter the checksum.
Security Cell
A security cell is provided in the GAL20V8 devices to prevent unauthorized copying of the array patterns. Once programmed, this
cell prevents further read access to the functional bits in the device.
This cell can only be erased by re-programming the device, so the
original configuration can never be examined once this cell is programmed. The Electronic Signature is always available to the user,
regardless of the state of this control cell.
Latch-Up Protection
GAL20V8 devices are designed with an on-board charge pump
to negatively bias the substrate. The negative bias minimizes the
potential of latch-up caused by negative input undershoots. Additionally, outputs are designed with n-channel pull-ups instead of
the traditional p-channel pull-ups in order to eliminate latch-up due
to output overshoots.
Device Programming
GAL devices are programmed using a Lattice Semiconductorapproved Logic Programmer, available from a number of manufacturers. Complete programming of the device takes only a few
seconds. Erasing of the device is transparent to the user, and is
done automatically as part of the programming cycle.
Typical Input Pull-up Characteristic
Output Register Preload
When testing state machine designs, all possible states and state
transitions must be verified in the design, not just those required
in the normal machine operations. This is because, in system
operation, certain events occur that may throw the logic into an
illegal state (power-up, line voltage glitches, brown-outs, etc.). To
test a design for proper treatment of these conditions, a way must
be provided to break the feedback paths, and force any desired (i.e.,
illegal) state into the registers. Then the machine can be sequenced
and the outputs tested for correct next state conditions.
GAL20V8 devices include circuitry that allows each registered
output to be synchronously set either high or low. Thus, any present
state condition can be forced for test sequencing. If necessary,
approved GAL programmers capable of executing text vectors
perform output register preload automatically.
Input Buffers
GAL20V8 devices are designed with TTL level compatible input
buffers. These buffers have a characteristically high impedance,
and present a much lighter load to the driving logic than bipolar TTL
devices.
The GAL20V8 input and I/O pins have built-in active pull-ups. As
a result, unused inputs and I/O's will float to a TTL "high" (logical
"1"). Lattice Semiconductor recommends that all unused inputs
and tri-stated I/O pins be connected to another active input, VCC,
or Ground. Doing this will tend to improve noise immunity and reduce ICC for the device.18

Output
Circuitry within the GAL20V8 provides a reset signal to all registers
during power-up. All internal registers will have their Q outputs set
low after a specified time (tpr, 1μs MAX). As a result, the state on
the registered output pins (if they are enabled) will always be high
on power-up, regardless of the programmed polarity of the output
pins. This feature can greatly simplify state machine design by providing a known state on power-up. Because of the asynchronous
nature of system power-up, some conditions must be met to provide

a valid power-up reset of the device. First, the VCC rise must be
monotonic. Second, the clock input must be at static TTL level as
shown in the diagram during power up. The registers will reset
within a maximum of tpr time. As in normal system operation, avoid
clocking the device until all input and feedback path setup times
have been met. The clock must also meet the minimum pulse width
requirements.

3-to-8 line decoder/demultiplexer with
address latches 74HC/HCT237
FEATURES
• Combines 3-to-8 decoder with 3-bit latch
• Multiple input enable for easy expansion or independent
controls
• Active HIGH mutually exclusive outputs
• Output capability: standard
• I
CC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT237 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT237 are 3-to-8 line decoder/demultiplexers
with latches at the three address inputs (An). The “237”
essentially combines the 3-to-8 decoder function with a
3-bit storage latch. When the latch is enabled (LE = LOW),
the “237” acts as a 3-to-8 active LOW decoder. When the
latch enable (LE) goes from LOW-to-HIGH, the last data
present at the inputs before this transition, is stored in the
latches. Further address changes are ignored as long as
LE remains HIGH.
The output enable input (E1 and E2) controls the state of
the outputs independent of the address inputs or latch
operation. All outputs are HIGH unless E1 is LOW and E2
is HIGH.
The “237” is ideally suited for implementing
non-overlapping decoders in 3-state systems and strobed
(stored address) applications in bus oriented systems.

DS10CP154A
1.5 Gbps 4x4 LVDS Crosspoint Switch
General Description
The DS10CP154A is a 1.5 Gbps 4x4 LVDS crosspoint switch
optimized for high-speed signal routing and switching over
FR-4 printed circuit board backplanes and balanced cables.
Fully differential signal paths ensure exceptional signal integrity and noise immunity. The non-blocking architecture
allows connections of any input to any output or outputs. The
switch configuration can be accomplished via external pins or
the System Management Bus (SMBus) interface. In addition,
the SMBus circuitry enables the loss of signal (LOS) monitors
that can inform a system of the presence of an open inputs
condition (e.g. disconnected cable).
Wide input common mode range allows the switch to accept
signals with LVDS, CML and LVPECL levels; the output levels
are LVDS. A very small package footprint requires a minimal
space on the board while the flow-through pinout allows easy
board layout. Each differential input and output is internally
terminated with a 100Ω resistor to lower return losses, reduce
component count and further minimize board space.
Features
■ DC - 1.5 Gbps low jitter, low skew, low power operation
■ Pin and SMBus configurable, fully differential, nonblocking architecture
■ Wide input common mode range enables DC coupled
interface to CML or LVPECL drivers
■ LOS circuitry detects open inputs fault condition
■ On-chip 100 Ω input and output termination minimizes
insertion and return losses, reduces component count and
minimizes board space
■ 8 kV ESD on LVDS I/O pins protects adjoining
components
■ Small 6 mm x 6 mm LLP-40 space saving package
Applications
■ High-speed channel select applications
■ Clock and data buffering and muxing
■ SD / HD SDI Routers

DS10CP154AFunctional Description
The DS10CP154A is a 1.5 Gbps 4x4 LVDS digital crosspoint
switch optimized for high-speed signal routing and switching
over lossy FR-4 printed circuit board backplanes and balanced cables. The DS10CP154A operates in two modes: Pin
Mode (EN_smb = 0) and SMBus Mode (EN_smb = 1).
When in the Pin Mode, the switch is fully configurable with
external pins. This is possible with two input select pins per
output (e.g. S00 and S01 pins for OUT0).
In the Pin Mode, feedback from the LOS (Loss Of Signal)
monitor circuitry is not available (there is not an LOS output
pin).
When in the SMBus Mode, the full switch configuration and
SoftPWDN can be programmed via the SMBus interface. In
addition, by using the SMBus interface, a user can obtain the
feedback from the built-in LOS circuitry which detects an open
inputs fault condition.
In the SMBus Mode, the S00 and S01 pins become SMBus
clock (SCL) input and data (SDA) input pins respectively; the
S10, S11, S21 and S21 pins become the User-Set SMBus
Slave Address input pins (ADDR0, 1, 2 and 3) while the S30
and S31 pins become non-functional (tieing these two pins to
either H or L is recommended if the device will function only
in the SMBus mode).
In the SMBus Mode, the PWDN pin remains functional. How
this pin functions in each mode is detailed in the following
sections.
DS10CP154A OPERATION IN THE PIN MODE
Power Up
In the Pin Mode, when the power is applied to the device
power suppy pins, the DS10CP154A enters the Power Up
mode when the PWDN pin is set to logic H. When in the Power
Down mode (PWDN pin is set to logic L), all circuitry is shut
down except the minimum required circuitry for the LOS and
SMBus Slave operation.
Switch Configuration
In the Pin Mode, the DS10CP154A operates as a fully pinconfigurable crosspoint switch. The following truth tables illustrate how the swich can be configured with external pins.

DS10CP154A OPERATION IN THE SMBUS MODE
The DS10CP154A operates as a slave on the System Management Bus (SMBus) when the EN_smb pin is set to a high
(1). Under these conditions, the SCL pin is a clock input while
the SDA pin is a serial data input pin.
Device Address
Based on the SMBus 2.0 specification, the DS10CP154A has
a 7-bit slave address. The three most significant bits of the
slave address are hard wired inside the DS10CP154A and
are “101”. The four least significant bits of the address are
assigned to pins ADDR3-ADDR0 and are set by connecting
these pins to GND for a low (0) or to VCC for a high (1). The
complete slave address is shown in the following table:
TABLE 5. DS10CP154A Slave Address
1 0 1 ADDR3 ADDR2 ADDR1 ADDR0
MSB LSB
This slave address configuration allows up to sixteen
DS10CP154A devices on a single SMBus bus.
Transfer of Data via the SMBus
During normal operation the data on SDA must be stable during the time when SCK is high.
There are three unique states for the SMBus:
START: A HIGH to LOW transition on SDA while SCK is high
indicates a message START condition.
STOP: A LOW to HIGH transition on SDA while SCK is high
indicates a message STOP condition.
IDLE: If SCK and SDA are both high for a time exceeding
tBUF from the last detected STOP condition or if they are high
for a total exceeding the maximum specification for tHIGH
then the bus will transfer to the IDLE state.
SMBus Transactions
A transaction begins with the host placing the DS10CP154A
SMBus into the START condition, then a byte (8 bits) is transferred, MSB first, followed by a ninth ACK bit. ACK bits are ‘0’
to signify an ACK, or ‘1’ to signify NACK, after this the host
holds the SCL line low, and waits for the receiver to raise the
SDA line as an ACKnowledge that the byte has been received.
Writing to a Register
To write a register, the following protocol is used (see SMBus
2.0 specification):
1) The Host drives a START condition, the 7-bit SMBus address, and a “0” indicating a WRITE.
2) The Device (Slave) drives an ACK bit (“0”).
3) The Host drives the 8-bit Register Address.
4) The Device drives an ACK bit (“0”).
5) The Host drives the 8-bit data byte.
6) The Device drives an ACK bit “0”.
7) The Host drives a STOP condition.
The WRITE transaction is completed, the bus goes Idle and
communication with other SMBus devices may now occur.
Reading From a Register
To read a register, the following protocol is used (see SMBus
2.0 specification):
1) The Host drives a START condition, the 7-bit SMBus address, and a “0” indicating a WRITE.
2) The Device (Slave) drives an ACK bit (“0”).
3) The Host drives the 8-bit Register Address.
4) The Device drives an ACK bit (“0”).
5) The Host drives a START condition.
6) The Host drives the 7-bit SMBus Address, and a “1” indicating a READ.
7) The Device drives an ACK bit “0”.
8) The Device drives the 8-bit data value (register contents).
9) The Host drives a NACK bit “1” indicating end of READ
transfer.
10) The Host drives a STOP condition.
The READ transaction is completed, the bus goes Idle and
communication with other SMBus devices may now occur.

DS10CP154A
1.5 Gbps 4x4 LVDS Crosspoint Switch
General Description
The DS10CP154A is a 1.5 Gbps 4x4 LVDS crosspoint switch
optimized for high-speed signal routing and switching over
FR-4 printed circuit board backplanes and balanced cables.
Fully differential signal paths ensure exceptional signal integrity and noise immunity. The non-blocking architecture
allows connections of any input to any output or outputs. The
switch configuration can be accomplished via external pins or
the System Management Bus (SMBus) interface. In addition,
the SMBus circuitry enables the loss of signal (LOS) monitors
that can inform a system of the presence of an open inputs
condition (e.g. disconnected cable).
Wide input common mode range allows the switch to accept
signals with LVDS, CML and LVPECL levels; the output levels
are LVDS. A very small package footprint requires a minimal
space on the board while the flow-through pinout allows easy
board layout. Each differential input and output is internally
terminated with a 100Ω resistor to lower return losses, reduce
component count and further minimize board space.
Features
■ DC - 1.5 Gbps low jitter, low skew, low power operation
■ Pin and SMBus configurable, fully differential, nonblocking architecture
■ Wide input common mode range enables DC coupled
interface to CML or LVPECL drivers
■ LOS circuitry detects open inputs fault condition
■ On-chip 100 Ω input and output termination minimizes
insertion and return losses, reduces component count and
minimizes board space
■ 8 kV ESD on LVDS I/O pins protects adjoining
components
■ Small 6 mm x 6 mm LLP-40 space saving package
Applications
■ High-speed channel select applications
■ Clock and data buffering and muxing
■ SD / HD SDI Routers

DS10CP154AFunctional Description
The DS10CP154A is a 1.5 Gbps 4x4 LVDS digital crosspoint
switch optimized for high-speed signal routing and switching
over lossy FR-4 printed circuit board backplanes and balanced cables. The DS10CP154A operates in two modes: Pin
Mode (EN_smb = 0) and SMBus Mode (EN_smb = 1).
When in the Pin Mode, the switch is fully configurable with
external pins. This is possible with two input select pins per
output (e.g. S00 and S01 pins for OUT0).
In the Pin Mode, feedback from the LOS (Loss Of Signal)
monitor circuitry is not available (there is not an LOS output
pin).
When in the SMBus Mode, the full switch configuration and
SoftPWDN can be programmed via the SMBus interface. In
addition, by using the SMBus interface, a user can obtain the
feedback from the built-in LOS circuitry which detects an open
inputs fault condition.
In the SMBus Mode, the S00 and S01 pins become SMBus
clock (SCL) input and data (SDA) input pins respectively; the
S10, S11, S21 and S21 pins become the User-Set SMBus
Slave Address input pins (ADDR0, 1, 2 and 3) while the S30
and S31 pins become non-functional (tieing these two pins to
either H or L is recommended if the device will function only
in the SMBus mode).
In the SMBus Mode, the PWDN pin remains functional. How
this pin functions in each mode is detailed in the following
sections.
DS10CP154A OPERATION IN THE PIN MODE
Power Up
In the Pin Mode, when the power is applied to the device
power suppy pins, the DS10CP154A enters the Power Up
mode when the PWDN pin is set to logic H. When in the Power
Down mode (PWDN pin is set to logic L), all circuitry is shut
down except the minimum required circuitry for the LOS and
SMBus Slave operation.
Switch Configuration
In the Pin Mode, the DS10CP154A operates as a fully pinconfigurable crosspoint switch. The following truth tables illustrate how the swich can be configured with external pins.

DS10CP154A OPERATION IN THE SMBUS MODE
The DS10CP154A operates as a slave on the System Management Bus (SMBus) when the EN_smb pin is set to a high
(1). Under these conditions, the SCL pin is a clock input while
the SDA pin is a serial data input pin.
Device Address
Based on the SMBus 2.0 specification, the DS10CP154A has
a 7-bit slave address. The three most significant bits of the
slave address are hard wired inside the DS10CP154A and
are “101”. The four least significant bits of the address are
assigned to pins ADDR3-ADDR0 and are set by connecting
these pins to GND for a low (0) or to VCC for a high (1). The
complete slave address is shown in the following table:
TABLE 5. DS10CP154A Slave Address
1 0 1 ADDR3 ADDR2 ADDR1 ADDR0
MSB LSB
This slave address configuration allows up to sixteen
DS10CP154A devices on a single SMBus bus.
Transfer of Data via the SMBus
During normal operation the data on SDA must be stable during the time when SCK is high.
There are three unique states for the SMBus:
START: A HIGH to LOW transition on SDA while SCK is high
indicates a message START condition.
STOP: A LOW to HIGH transition on SDA while SCK is high
indicates a message STOP condition.
IDLE: If SCK and SDA are both high for a time exceeding
tBUF from the last detected STOP condition or if they are high
for a total exceeding the maximum specification for tHIGH
then the bus will transfer to the IDLE state.
SMBus Transactions
A transaction begins with the host placing the DS10CP154A
SMBus into the START condition, then a byte (8 bits) is transferred, MSB first, followed by a ninth ACK bit. ACK bits are ‘0’
to signify an ACK, or ‘1’ to signify NACK, after this the host
holds the SCL line low, and waits for the receiver to raise the
SDA line as an ACKnowledge that the byte has been received.
Writing to a Register
To write a register, the following protocol is used (see SMBus
2.0 specification):
1) The Host drives a START condition, the 7-bit SMBus address, and a “0” indicating a WRITE.
2) The Device (Slave) drives an ACK bit (“0”).
3) The Host drives the 8-bit Register Address.
4) The Device drives an ACK bit (“0”).
5) The Host drives the 8-bit data byte.
6) The Device drives an ACK bit “0”.
7) The Host drives a STOP condition.
The WRITE transaction is completed, the bus goes Idle and
communication with other SMBus devices may now occur.
Reading From a Register
To read a register, the following protocol is used (see SMBus
2.0 specification):
1) The Host drives a START condition, the 7-bit SMBus address, and a “0” indicating a WRITE.
2) The Device (Slave) drives an ACK bit (“0”).
3) The Host drives the 8-bit Register Address.
4) The Device drives an ACK bit (“0”).
5) The Host drives a START condition.
6) The Host drives the 7-bit SMBus Address, and a “1” indicating a READ.
7) The Device drives an ACK bit “0”.
8) The Device drives the 8-bit data value (register contents).
9) The Host drives a NACK bit “1” indicating end of READ
transfer.
10) The Host drives a STOP condition.
The READ transaction is completed, the bus goes Idle and
communication with other SMBus devices may now occur.
