1. General description
NXP Semiconductors designed the LPC2468 microcontroller around a 16-bit/32-bit
ARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG and
embedded trace. The LPC2468 has 512 kB of on-chip high-speed flash memory. This
flash memory includes a special 128-bit wide memory interface and accelerator
architecture that enables the CPU to execute sequential instructions from flash memory at
the maximum 72 MHz system clock rate. This feature is available only on the LPC2000
ARM microcontroller family of products. The LPC2468 can execute both 32-bit ARM and
16-bit Thumb instructions. Support for the two instruction sets means engineers can
choose to optimize their application for either performance or code size at the sub-routine
level. When the core executes instructions in Thumb state it can reduce code size by
more than 30 % with only a small loss in performance while executing instructions in ARM
state maximizes core performance.
The LPC2468 microcontroller is ideal for multi-purpose communication applications. It
incorporates a 10/100 Ethernet Media Access Controller (MAC), a USB full-speed
Device/Host/OTG Controller with 4 kB of endpoint RAM, four UARTs, two Controller Area
Network (CAN) channels, an SPI interface, two Synchronous Serial Ports (SSP), three I2C
interfaces, and an I2S interface. Supporting this collection of serial communications
interfaces are the following feature components; an on-chip 4 MHz internal precision
oscillator, 98 kB of total RAM consisting of 64 kB of local SRAM, 16 kB SRAM for
Ethernet, 16 kB SRAM for general purpose DMA, 2 kB of battery powered SRAM, and an
External Memory Controller (EMC). These features make this device optimally suited for
communication gateways and protocol converters. Complementing the many serial
communication controllers, versatile clocking capabilities, and memory features are
various 32-bit timers, an improved 10-bit ADC, 10-bit DAC, two PWM units, four external
interrupt pins, and up to 160 fast GPIO lines. The LPC2468 connects 64 of the GPIO pins
to the hardware based Vector Interrupt Controller (VIC) that means these external inputs
can generate edge-triggered interrupts. All of these features make the LPC2468
particularly suitable for industrial control and medical systems.
2. Features and benefits

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
7. Functional description
7.1 Architectural overview
The LPC2468 microcontroller consists of an ARM7TDMI-S CPU with emulation support,
the ARM7 local bus for closely coupled, high-speed access to the majority of on-chip
memory, the AMBA AHB interfacing to high-speed on-chip peripherals and external
memory, and the AMBA APB for connection to other on-chip peripheral functions. The
microcontroller permanently configures the ARM7TDMI-S processor for little-endian byte
order.
The LPC2468 implements two AHBs in order to allow the Ethernet block to operate
without interference caused by other system activity. The primary AHB, referred to as
AHB1, includes the VIC, GPDMA controller, and EMC.
The second AHB, referred to as AHB2, includes only the Ethernet block and an
associated 16 kB SRAM. In addition, a bus bridge is provided that allows the secondary
AHB to be a bus master on AHB1, allowing expansion of Ethernet buffer space into
off-chip memory or unused space in memory residing on AHB1.
In summary, bus masters with access to AHB1 are the ARM7 itself, the GPDMA function,
and the Ethernet block (via the bus bridge from AHB2). Bus masters with access to AHB2
are the ARM7 and the Ethernet block.
AHB peripherals are allocated a 2 MB range of addresses at the very top of the 4 GB
ARM memory space. Each AHB peripheral is allocated a 16 kB address space within the
AHB address space. Lower speed peripheral functions are connected to the APB. The
AHB to APB bridge interfaces the APB to the AHB. APB peripherals are also allocated a
2 MB range of addresses, beginning at the 3.5 GB address point. Each APB peripheral is
allocated a 16 kB address space within the APB address space.
The ARM7TDMI-S processor is a general purpose 32-bit microprocessor, which offers
high performance and very low power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles, and the instruction set and related
decode mechanism are much simpler than those of microprogrammed complex
instruction set computers. This simplicity results in a high instruction throughput and
impressive real-time interrupt response from a small and cost-effective processor core.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM7TDMI-S processor also employs a unique architectural strategy known as
Thumb, which makes it ideally suited to high-volume applications with memory
restrictions, or applications where code density is an issue.
The key idea behind Thumb is that of a super-reduced instruction set. Essentially, the
ARM7TDMI-S processor has two instruction sets:
• the standard 32-bit ARM set
• a 16-bit Thumb set

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
The Thumb set’s 16-bit instruction length allows it to approach higher density compared to
standard ARM code while retaining most of the ARM’s performance.
7.2 On-chip flash programming memory
The LPC2468 incorporates 512 kB flash memory system. This memory may be used for
both code and data storage. Programming of the flash memory may be accomplished in
several ways. It may be programmed In System via the serial port (UART0). The
application program may also erase and/or program the flash while the application is
running, allowing a great degree of flexibility for data storage field and firmware upgrades.
The flash memory is 128 bits wide and includes pre-fetching and buffering techniques to
allow it to operate at speeds of 72 MHz.
7.3 On-chip SRAM
The LPC2468 includes a SRAM memory of 64 kB reserved for the ARM processor
exclusive use. This RAM may be used for code and/or data storage and may be accessed
as 8 bits, 16 bits, and 32 bits.
A 16 kB SRAM block serving as a buffer for the Ethernet controller and a 16 kB SRAM
associated with the second AHB can be used both for data and code storage. The 2 kB
RTC SRAM can be used for data storage only. The RTC SRAM is battery powered and
retains the content in the absence of the main power supply.
7.4 Memory map
The LPC2468 memory map incorporates several distinct regions as shown in Table 5 and
Figure 4.
In addition, the CPU interrupt vectors may be remapped to allow them to reside in either
flash memory (default), boot ROM or SRAM (see Section 7.26.6).

7.5 Interrupt controller
The ARM processor core has two interrupt inputs called Interrupt ReQuest (IRQ) and Fast
Interrupt ReQuest (FIQ). The VIC takes 32 interrupt request inputs which can be
programmed as FIQ or vectored IRQ types. The programmable assignment scheme
means that priorities of interrupts from the various peripherals can be dynamically
assigned and adjusted.
FIQs have the highest priority. If more than one request is assigned to FIQ, the VIC ORs
the requests to produce the FIQ signal to the ARM processor. The fastest possible FIQ
latency is achieved when only one request is classified as FIQ, because then the FIQ

service routine can simply start dealing with that device. But if more than one request is
assigned to the FIQ class, the FIQ service routine can read a word from the VIC that
identifies which FIQ source(s) is (are) requesting an interrupt.
Vectored IRQs, which include all interrupt requests that are not classified as FIQs, have a
programmable interrupt priority. When more than one interrupt is assigned the same
priority and occur simultaneously, the one connected to the lowest numbered VIC channel
will be serviced first.
The VIC ORs the requests from all of the vectored IRQs to produce the IRQ signal to the
ARM processor. The IRQ service routine can start by reading a register from the VIC and
jumping to the address supplied by that register.
7.5.1 Interrupt sources
Each peripheral device has one interrupt line connected to the VIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
Any pin on port 0 and port 2 (total of 64 pins) regardless of the selected function, can be
programmed to generate an interrupt on a rising edge, a falling edge, or both. Such
interrupt request coming from port 0 and/or port 2 will be combined with the EINT3
interrupt requests.
7.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
7.7 External memory controller
The LPC2468 EMC is an ARM PrimeCell MultiPort Memory Controller peripheral offering
support for asynchronous static memory devices such as RAM, ROM, and flash. In
addition, it can be used as an interface with off-chip memory-mapped devices and
peripherals. The EMC is an Advanced Microcontroller Bus Architecture (AMBA) compliant
peripheral.
7.7.1 Features
• Dynamic memory interface support including single data rate SDRAM.
• Asynchronous static memory device support including RAM, ROM, and flash, with or
without asynchronous page mode.
• Low transaction latency.
• Read and write buffers to reduce latency and to improve performance.
• 8/16/32 data and 24 address lines wide static memory support.
• 16 bit and 32 bit wide chip select SDRAM memory support.
• Static memory features include:

Single-chip 16-bit/32-bit micro
– Asynchronous page mode read
– Programmable Wait States
– Bus turnaround delay
– Output enable and write enable delays
– Extended wait
• Four chip selects for synchronous memory and four chip selects for static memory
devices.
• Power-saving modes dynamically control CKE and CLKOUT to SDRAMs
• Dynamic memory self-refresh mode controlled by software.
• Controller supports 2048, 4096, and 8192 row address synchronous memory parts.
That is typical 512 MB, 256 MB, and 128 MB parts, with 4, 8, 16, or 32 data bits per
device.
• Separate reset domains allow the for auto-refresh through a chip reset if desired.
Note: Synchronous static memory devices (synchronous burst mode) are not supported.
7.8 General purpose DMA controller
The GPDMA is an AMBA AHB compliant peripheral allowing selected LPC2468
peripherals to have DMA support.
The GPDMA enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receive. The
source and destination areas can each be either a memory region or a peripheral, and
can be accessed through the AHB master.
7.8.1 Features
• Two DMA channels. Each channel can support a unidirectional transfer.
• The GPDMA can transfer data between the 16 kB SRAM, external memory, and
peripherals such as the SD/MMC, two SSPs, and the I2S interface.
• Single DMA and burst DMA request signals. Each peripheral connected to the
GPDMA can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the GPDMA.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority. Each DMA channel has a specific hardware priority.
DMA channel 0 has the highest priority and channel 1 has the lowest priority. If
requests from two channels become active at the same time, the channel with the
highest priority is serviced first.
• AHB slave DMA programming interface. The GPDMA is programmed by writing to the
DMA control registers over the AHB slave interface.

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
• One AHB master for transferring data. This interface transfers data when a DMA
request goes active.
• 32-bit AHB master bus width.
• Incrementing or non-incrementing addressing for source and destination.
• Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data. Usually the burst size is set to half the size of the FIFO in the
peripheral.
• Internal four-word FIFO per channel.
• Supports 8-bit, 16-bit, and 32-bit wide transactions.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Interrupt masking. The DMA error and DMA terminal count interrupt requests can be
masked.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
7.9 Fast general purpose parallel I/O
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.
LPC2468 use accelerated GPIO functions:
• GPIO registers are relocated to the ARM local bus so that the fastest possible I/O
timing can be achieved.
• Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
• All GPIO registers are byte and half-word addressable.
• Entire port value can be written in one instruction.
Additionally, any pin on port 0 and port 2 (total of 64 pins) that is not configured as an
analog input/output can be programmed to generate an interrupt on a rising edge, a falling
edge, or both. The edge detection is asynchronous, so it may operate when clocks are not
present such as during Power-down mode. Each enabled interrupt can be used to wake
the chip up from Power-down mode.
7.9.1 Features
• Bit level set and clear registers allow a single instruction to set or clear any number of
bits in one port.
• Direction control of individual bits.
• All I/O default to inputs after reset.
• Backward compatibility with other earlier devices is maintained with legacy port 0 and
port 1 registers appearing at the original addresses on the APB.

7.10 Ethernet
The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC
designed to provide optimized performance through the use of DMA hardware
acceleration. Features include a generous suite of control registers, half or full duplex
operation, flow control, control frames, hardware acceleration for transmit retry, receive
packet filtering and wake-up on LAN activity. Automatic frame transmission and reception
with scatter-gather DMA off-loads many operations from the CPU.
The Ethernet block and the CPU share a dedicated AHB subsystem that is used to access
the Ethernet SRAM for Ethernet data, control, and status information. All other AHB traffic
in the LPC2468 takes place on a different AHB subsystem, effectively separating Ethernet
activity from the rest of the system. The Ethernet DMA can also access off-chip memory
via the EMC, as well as the SRAM located on another AHB. However, using memory
other than the Ethernet SRAM, especially off-chip memory, will slow Ethernet access to
memory and increase the loading of its AHB.
The Ethernet block interfaces between an off-chip Ethernet PHY using the Media
Independent Interface (MII) or Reduced MII (RMII) protocol and the on-chip Media
Independent Interface Management (MIIM) serial bus.

7.11 USB interface
The Universal Serial Bus (USB) is a 4-wire bus that supports communication between a
host and one or more (up to 127) peripherals. The host controller allocates the USB
bandwidth to attached devices through a token-based protocol. The bus supports hot
plugging and dynamic configuration of the devices. All transactions are initiated by the
host controller.
The LPC2468 USB interface includes a device, host, and OTG controller. Details on
typical USB interfacing solutions can be found in Section 14.1 “Suggested USB interface
solutions” on page 69.
7.11.1 USB device controller
The device controller enables 12 Mbit/s data exchange with a USB host controller. It
consists of a register interface, serial interface engine, endpoint buffer memory, and a
DMA controller. The serial interface engine decodes the USB data stream and writes data
to the appropriate endpoint buffer. The status of a completed USB transfer or error
condition is indicated via status registers. An interrupt is also generated if enabled. When
enabled, the DMA controller transfers data between the endpoint buffer and the USB
RAM.

7.12 CAN controller and acceptance filters
The Controller Area Network (CAN) is a serial communications protocol which efficiently
supports distributed real-time control with a very high level of security. Its domain of
application ranges from high-speed networks to low cost multiplex wiring.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router between two of CAN buses in industrial
or automotive applications.
Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN
Library block, but the 8-bit registers of those devices have been combined in 32-bit words
to allow simultaneous access in the ARM environment. The main operational difference is
that the recognition of received Identifiers, known in CAN terminology as Acceptance
Filtering, has been removed from the CAN controllers and centralized in a global
Acceptance Filter.
7.12.1 Features
• Two CAN controllers and buses.
• Data rates to 1 Mbit/s on each bus.

The LPC2468 contains one SPI controller. SPI is a full duplex serial interface designed to
handle multiple masters and slaves connected to a given bus. Only a single master and a
single slave can communicate on the interface during a given data transfer. During a data
transfer the master always sends 8 bits to 16 bits of data to the slave, and the slave
always sends 8 bits to 16 bits of data to the master.
7.16.1 Features
• Compliant with SPI specification
• Synchronous, Serial, Full Duplex Communication
• Combined SPI master and slave
• Maximum data bit rate of one eighth of the input clock rate

7.17 SSP serial I/O controller
The LPC2468 contains two SSP controllers. The SSP controller is capable of operation on
a SPI, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the
bus. Only a single master and a single slave can communicate on the bus during a given
data transfer. The SSP supports full duplex transfers, with frames of 4 bits to 16 bits of
data flowing from the master to the slave and from the slave to the master. In practice,
often only one of these data flows carries meaningful data.

7.19 I2C-bus serial I/O controller
The LPC2468 contains three I2C-bus controllers.
The I2C-bus is bidirectional, for inter-IC control using only two wires: a Serial Clock Line
(SCL), and a Serial Data Line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C-bus is a multi-master bus and can
be controlled by more than one bus master connected to it.
The I2C-bus implemented in LPC2468 supports bit rates up to 400 kbit/s (Fast I2C-bus).
7.19.1 Features
• I
2C0 is a standard I2C compliant bus interface with open-drain pins.
• I
2C1 and I2C2 use standard I/O pins and do not support powering off of individual
devices connected to the same bus lines.
• Easy to configure as master, slave, or master/slave.
• Programmable clocks allow versatile rate control.
• Bidirectional data transfer between masters and slaves.
• Multi-master bus (no central master).
• Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
• Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
• Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
• The I2C-bus can be used for test and diagnostic purposes.
7.20 I2S-bus serial I/O controllers
The I2S-bus provides a standard communication interface for digital audio applications.

Product data sheet Rev. 6.2 — 11 January 2013 37 of 85
NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
The I
2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I2S connection has one master, which is always the
master, and one slave. The I2S interface on the LPC2468 provides a separate transmit
and receive channel, each of which can operate as either a master or a slave.
7.20.1 Features
• The interface has separate input/output channels each of which can operate in master
or slave mode.
• Capable of handling 8-bit, 16-bit, and 32-bit word sizes.
• Mono and stereo audio data supported.
• The sampling frequency can range from 16 kHz to 48 kHz (16, 22.05, 32, 44.1,
48) kHz.
• Configurable word select period in master mode (separately for I2S input and output).
• Two 8 word FIFO data buffers are provided, one for transmit and one for receive.

7.21 General purpose 32-bit timers/external event counters
The LPC2468 includes four 32-bit Timer/Counters. The Timer/Counter is designed to
count cycles of the system derived clock or an externally-supplied clock. It can optionally
generate interrupts or perform other actions at specified timer values, based on four
match registers. The Timer/Counter also includes four capture inputs to trap the timer
value when an input signal transitions, optionally generating an interrupt.
7.21.1 Features
• A 32-bit Timer/Counter with a programmable 32-bit prescaler.
• Counter or Timer operation.
• Up to four 32-bit capture channels per timer, that can take a snapshot of the timer
value when an input signal transitions. A capture event may also optionally generate
an interrupt.

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
7.22 Pulse width modulator
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC2468. The Timer is designed to count
cycles of the system derived clock and optionally switch pins, generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is in addition to these features and is based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. A
dedicated match register controls the PWM cycle rate, by resetting the count upon match.
The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, a dedicated match register controls the PWM cycle rate. The other match registers
control the two PWM edge positions. Additional double edge controlled PWM outputs
require only two match registers each, since the repetition rate is the same for all PWM
outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
7.22.1 Features
• LPC2468 has two PWMs with the same operational features. These may be operated
in a synchronized fashion by setting them both up to run at the same rate, then
enabling both simultaneously. PWM0 acts as the master and PWM1 as the slave for
this use.
• Counter or Timer operation (may use the peripheral clock or one of the capture inputs
as the clock source).
• Seven match registers allow up to 6 single edge controlled or 3 double edge
controlled PWM outputs, or a mix of both types. The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go HIGH at the beginning of each cycle unless the
output is a constant LOW. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard timer if the PWM mode is not enabled.
• A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
7.23 Watchdog timer
The purpose of the watchdog is to reset the microcontroller within a reasonable amount of
time if it enters an erroneous state. When enabled, the watchdog will generate a system
reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined
amount of time.
7.23.1 Features
• Internally resets chip if not periodically reloaded.
• Debug mode.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 32-bit timer with internal prescaler.
• Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 232 4) in
multiples of Tcy(WDCLK) 4.
• The Watchdog Clock (WDCLK) source can be selected from the RTC clock, the
Internal RC oscillator (IRC), or the APB peripheral clock. This gives a wide range of
potential timing choices of Watchdog operation under different power reduction
conditions. It also provides the ability to run the WDT from an entirely internal source
that is not dependent on an external crystal and its associated components and
wiring, for increased reliability.
7.24 RTC and battery RAM
The RTC is a set of counters for measuring time when system power is on, and optionally
when power is off. It uses little power in Power-down and Deep power-down modes. On
the LPC2468, the RTC can be clocked by a separate 32.768 kHz oscillator or by a
programmable prescale divider based on the APB clock. The RTC is powered by its own
power supply pin, VBAT, which can be connected to a battery or to the same 3.3 V supply
used by the rest of the device.

Product data sheet Rev. 6.2 — 11 January 2013 40 of 85
NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
The VBAT pin supplies power only to the RTC and the Battery RAM. These two functions
require a minimum of power to operate, which can be supplied by an external battery.
When the CPU and the rest of chip functions are stopped and power is removed, the RTC
can supply an alarm output that can be used by external hardware to restore chip power
and resume operation.
7.24.1 Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra low power design to support battery powered systems.
• Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.
• Dedicated 32 kHz oscillator or programmable prescaler from APB clock.
• Dedicated power supply pin can be connected to a battery or to the main 3.3 V.
• An alarm output pin is included to assist in waking up when the chip has had power
removed to all functions except the RTC and Battery RAM.
• Periodic interrupts can be generated from increments of any field of the time registers,
and selected fractional second values. This enhancement enables the RTC to be
used as a System Timer.
• 2 kB data SRAM powered by VBAT.
• RTC and Battery RAM power supply is isolated from the rest of the chip.
7.25 Clocking and power control
7.25.1 Crystal oscillators
The LPC2468 includes three independent oscillators. These are the Main Oscillator, the
Internal RC oscillator, and the RTC oscillator. Each oscillator can be used for more than
one purpose as required in a particular application. Any of the three clock sources can be
chosen by software to drive the PLL and ultimately the CPU.
Following reset, the LPC2468 will operate from the Internal RC oscillator until switched by
software. This allows systems to operate without any external crystal and the bootloader
code to operate at a known frequency.
7.25.1.1 Internal RC oscillator
The IRC may be used as the clock source for the WDT, and/or as the clock that drives the
PLL and subsequently the CPU. The nominal IRC frequency is 4 MHz. The IRC is
trimmed to 1 % accuracy.
Upon power-up or any chip reset, the LPC2468 uses the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.25.1.2 Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can
be boosted to a higher frequency, up to the maximum CPU operating frequency, by the
PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock
frequency is referred to as CCLK elsewhere in this document. The frequencies of

Product data sheet Rev. 6.2 — 11 January 2013 41 of 85
NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The
clock frequency for each peripheral can be selected individually and is referred to as
PCLK. Refer to Section 7.25.2 for additional information.
7.25.1.3 RTC oscillator
The RTC oscillator can be used as the clock source for the RTC and/or the WDT. Also, the
RTC oscillator can be used to drive the PLL and the CPU.
7.25.2 PLL
The PLL accepts an input clock frequency in the range of 32 kHz to 25 MHz. The input
frequency is multiplied up to a high frequency, then divided down to provide the actual
clock used by the CPU and the USB block.
The PLL input, in the range of 32 kHz to 25 MHz, may initially be divided down by a value
‘N’, which may be in the range of 1 to 256. This input division provides a wide range of
output frequencies from the same input frequency.
Following the PLL input divider is the PLL multiplier. This can multiply the input divider
output through the use of a Current Controlled Oscillator (CCO) by a value ‘M’, in the
range of 1 through 32768. The resulting frequency must be in the range of 275 MHz to
550 MHz. The multiplier works by dividing the CCO output by the value of M, then using a
phase-frequency detector to compare the divided CCO output to the multiplier input. The
error value is used to adjust the CCO frequency.
The PLL is turned off and bypassed following a chip Reset and by entering Power-down
mode. PLL is enabled by software only. The program must configure and activate the PLL,
wait for the PLL to lock, then connect to the PLL as a clock source.
7.25.3 Wake-up timer
The LPC2468 begins operation at power-up and when awakened from Power-down and
Deep power-down modes by using the 4 MHz IRC oscillator as the clock source. This
allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the
application, software will need to enable these features and wait for them to stabilize
before they are used as a clock source.
When the main oscillator is initially activated, the Wake-up Timer allows software to
ensure that the main oscillator is fully functional before the processor uses it as a clock
source and starts to execute instructions. This is important at power on, all types of Reset,
and whenever any of the aforementioned functions are turned off for any reason. Since
the oscillator and other functions are turned off during Power-down and Deep power-down
modes, any wake-up of the processor from Power-down modes makes use of the
Wake-up Timer.
The Wake-up Timer monitors the crystal oscillator to check whether it is safe to begin
code execution. When power is applied to the chip, or when some event caused the chip
to exit Power-down mode, some time is required for the oscillator to produce a signal of
sufficient amplitude to drive the clock logic. The amount of time depends on many factors,
including the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its
electrical characteristics (if a quartz crystal is used), as well as any other external circuitry
(e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
7.25.4 Power control
The LPC2468 supports a variety of power control features. There are four special modes
of processor power reduction: Idle mode, Sleep mode, Power-down mode, and Deep
power-down mode. The CPU clock rate may also be controlled as needed by changing
clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This
allows a trade-off of power versus processing speed based on application requirements.
In addition, Peripheral power control allows shutting down the clocks to individual on-chip
peripherals, allowing fine tuning of power consumption by eliminating all dynamic power
use in any peripherals that are not required for the application. Each of the peripherals
has its own clock divider which provides even better power control.
The LPC2468 also implements a separate power domain in order to allow turning off
power to the bulk of the device while maintaining operation of the RTC and a small SRAM,
referred to as the Battery RAM.
7.25.4.1 Idle mode
In Idle mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Idle mode and may generate
interrupts to cause the processor to resume execution. Idle mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
7.25.4.2 Sleep mode
In Sleep mode, the oscillator is shut down and the chip receives no internal clocks. The
processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Sleep mode and the logic levels of chip pins remain static. The
output of the IRC is disabled but the IRC is not powered down for a fast wake-up later. The
32 kHz RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The CCLK and
USB clock dividers automatically get reset to zero.
The Sleep mode can be terminated and normal operation resumed by either a Reset or
certain specific interrupts that are able to function without clocks. Since all dynamic
operation of the chip is suspended, Sleep mode reduces chip power consumption to a
very low value. The flash memory is left on in Sleep mode, allowing a very quick wake-up.
On the wake-up from Sleep mode, if the IRC was used before entering Sleep mode, the
code execution and peripherals activities will resume after 4 cycles expire. If the main
external oscillator was used, the code execution will resume when 4096 cycles expire.
The customers need to reconfigure the PLL and clock dividers accordingly.
7.25.4.3 Power-down mode
Power-down mode does everything that Sleep mode does, but also turns off the IRC
oscillator and the flash memory. This saves more power, but requires waiting for
resumption of flash operation before execution of code or data access in the flash memory
can be accomplished.
On the wake-up from Power-down mode, if the IRC was used before entering
Power-down mode, it will take IRC 60 s to start-up. After this 4 IRC cycles will expire
before the code execution can then be resumed if the code was running from SRAM. In

Single-chip 16-bit/32-bit micro
the meantime, the flash Wake-up Timer then counts 4 MHz IRC clock cycles to make the
100 s flash start-up time. When it times out, access to the flash will be allowed. The
customers need to reconfigure the PLL and clock dividers accordingly.
7.25.4.4 Deep power-down mode
Deep power-down mode is similar to the Power-down mode, but now the on-chip
regulator that supplies power to the internal logic is also shut off. This produces the lowest
possible power consumption without removing power from the entire chip. Since the Deep
power-down mode shuts down the on-chip logic power supply, there is no register or
memory retention, and resumption of operation involves the same activities as a full chip
reset.
If power is supplied to the LPC2468 during Deep power-down mode, wake-up can be
caused by the RTC Alarm interrupt or by external Reset.
While in Deep power-down mode, external device power may be removed. In this case,
the LPC2468 will start up when external power is restored.
Essential data may be retained through Deep power-down mode (or through complete
powering off of the chip) by storing data in the Battery RAM, as long as the external power
to the VBAT pin is maintained.
7.25.4.5 Power domains
The LPC2468 provides two independent power domains that allow the bulk of the device
to have power removed while maintaining operation of the RTC and the Battery RAM.
On the LPC2468, I/O pads are powered by the 3.3 V (VDD(3V3)) pins, while the
VDD(DCDC)(3V3) pins power the on-chip DC-to-DC converter which in turn provides power to
the CPU and most of the peripherals.
Although both the I/O pad ring and the core require a 3.3 V supply, different powering
schemes can be used depending on the actual application requirements.
The first option assumes that power consumption is not a concern and the design ties the
VDD(3V3) and VDD(DCDC)(3V3) pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and
a dedicated 3.3 V supply for the CPU (VDD(DCDC)(3V3)). Having the on-chip DC-DC
converter powered independently from the I/O pad ring enables shutting down of the I/O
pad power supply “on the fly”, while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC and the Battery RAM. These two functions
require a minimum of power to operate, which can be supplied by an external battery.
When the CPU and the rest of chip functions are stopped and power removed, the RTC
can supply an alarm output that may be used by external hardware to restore chip power
and resume operation.

7.26 System control
7.26.1 Reset
Reset has four sources on the LPC2468: the RESET pin, the Watchdog reset, power-on
reset, and the BrownOut Detection (BOD) circuit. The RESET pin is a Schmitt trigger input
pin. Assertion of chip Reset by any source, once the operating voltage attains a usable
level, starts the Wake-up Timer (see description in Section 7.25.3 “Wake-up timer”),
causing reset to remain asserted until the external Reset is de-asserted, the oscillator is
running, a fixed number of clocks have passed, and the flash controller has completed its
initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the Boot Block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
7.26.2 Brownout detection
The LPC2468 includes 2-stage monitoring of the voltage on the VDD(DCDC)(3V3) pins. If this
voltage falls below 2.95 V, the BOD asserts an interrupt signal to the Vectored Interrupt
Controller. This signal can be enabled for interrupt in the Interrupt Enable Register in the
VIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a
dedicated status register.
The second stage of low-voltage detection asserts Reset to inactivate the LPC2468 when
the voltage on the VDD(DCDC)(3V3) pins falls below 2.65 V. This Reset prevents alteration of
the flash as operation of the various elements of the chip would otherwise become
unreliable due to low voltage. The BOD circuit maintains this reset down below 1 V, at
which point the power-on reset circuitry maintains the overall Reset.
Both the 2.95 V and 2.65 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.95 V detection to reliably interrupt, or a regularly-executed event
loop to sense the condition.
7.26.3 Code security (Code Read Protection - CRP)
This feature of the LPC2468 allows user to enable different levels of security in the system
so that access to the on-chip flash and use of the JTAG and ISP can be restricted. When
needed, CRP is invoked by programming a specific pattern into a dedicated flash location.
IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10]/EINT0
pin, too. It is up to the user’s application to provide (if needed) flash update mechanism
using IAP calls or call reinvoke ISP command to enable flash update via UART0.

7.26.4 AHB
The LPC2468 implements two AHB in order to allow the Ethernet block to operate without
interference caused by other system activity. The primary AHB, referred to as AHB1,
includes the Vectored Interrupt Controller, GPDMA controller, USB interface, and 16 kB
SRAM.
The second AHB, referred to as AHB2, includes only the Ethernet block and an
associated 16 kB SRAM. In addition, a bus bridge is provided that allows the secondary
AHB to be a bus master on AHB1, allowing expansion of Ethernet buffer space into
off-chip memory or unused space in memory residing on AHB1.
In summary, bus masters with access to AHB1 are the ARM7 itself, the USB block, the
GPDMA function, and the Ethernet block (via the bus bridge from AHB2). Bus masters
with access to AHB2 are the ARM7 and the Ethernet block.
7.26.5 External interrupt inputs
The LPC2468 includes up to 68 edge sensitive interrupt inputs combined with up to four
level sensitive external interrupt inputs as selectable pin functions. The external interrupt
inputs can optionally be used to wake up the processor from Power-down mode.
7.26.6 Memory mapping control
The memory mapping control alters the mapping of the interrupt vectors that appear at the
beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the Boot
ROM, the SRAM, or external memory. This allows code running in different memory
spaces to have control of the interrupts.
7.27 Emulation and debugging
The LPC2468 support emulation and debugging via a JTAG serial port. A trace port allows
tracing program execution. Debugging and trace functions are multiplexed only with
GPIOs on P2[0] to P2[9]. This means that all communication, timer, and interface
peripherals residing on other pins are available during the development and debugging
phase as they are when the application is run in the embedded system itself.
7.27.1 EmbeddedICE
The EmbeddedICE logic provides on-chip debug support. The debugging of the target
system requires a host computer running the debugger software and an EmbeddedICE
protocol convertor. The EmbeddedICE protocol convertor converts the Remote Debug
Protocol commands to the JTAG data needed to access the ARM7TDMI-S core present
on the target system.
The ARM core has a Debug Communication Channel (DCC) function built-in. The DCC
allows a program running on the target to communicate with the host debugger or another
separate host without stopping the program flow or even entering the debug state. The
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.

NXP Semiconductors LPC2468
Single-chip 16-bit/32-bit micro
DCC is accessed as a coprocessor 14 by the program running on the ARM7TDMI-S core.
The DCC allows the JTAG port to be used for sending and receiving data without affecting
the normal program flow. The DCC data and control registers are mapped in to addresses
in the EmbeddedICE logic.
The JTAG clock (TCK) must be slower than 1⁄
6 of the CPU clock (CCLK) for the JTAG
interface to operate.
7.27.2 Embedded trace
Since the LPC2468 have significant amounts of on-chip memories, it is not possible to
determine how the processor core is operating simply by observing the external pins. The
ETM provides real-time trace capability for deeply embedded processor cores. It outputs
information about processor execution to a trace port. A software debugger allows
configuration of the ETM using a JTAG interface and displays the trace information that
has been captured.
The ETM is connected directly to the ARM core and not to the main AMBA system bus. It
compresses the trace information and exports it through a narrow trace port. An external
Trace Port Analyzer captures the trace information under software debugger control. The
trace port can broadcast the Instruction trace information. Instruction trace (or PC trace)
shows the flow of execution of the processor and provides a list of all the instructions that
were executed. Instruction trace is significantly compressed by only broadcasting branch
addresses as well as a set of status signals that indicate the pipeline status on a cycle by
cycle basis. Trace information generation can be controlled by selecting the trigger
resource. Trigger resources include address comparators, counters and sequencers.
Since trace information is compressed the software debugger requires a static image of
the code being executed. Self-modifying code can not be traced because of this
restriction.
7.27.3 RealMonitor
RealMonitor is a configurable software module, developed by ARM Inc., which enables
real-time debug. It is a lightweight debug monitor that runs in the background while users
debug their foreground application. It communicates with the host using the DCC, which is
present in the EmbeddedICE logic. The LPC2468 contain a specific configuration of
RealMonitor software programmed into the on-chip ROM memory.

9. Thermal characteristics
The average chip junction temperature, Tj (C), can be calculated using the following
equation:
(1)
• Tamb = ambient temperature (C),
• Rth(j-a) = the package junction-to-ambient thermal resistance (C/W)
• PD = sum of internal and I/O power dissipation
The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of
the I/O pins is often small and many times can be negligible. However it can be significant
in some applications.

1. General description
The LPC2141/42/44/46/48 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S
CPU with real-time emulation and embedded trace support, that combine the
microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB. A
128-bit wide memory interface and a unique accelerator architecture enable 32-bit code
execution at the maximum clock rate. For critical code size applications, the alternative
16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
Due to their tiny size and low power consumption, LPC2141/42/44/46/48 are ideal for
applications where miniaturization is a key requirement, such as access control and
point-of-sale. Serial communications interfaces ranging from a USB 2.0 Full-speed
device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of 8 kB up to 40 kB,
make these devices very well suited for communication gateways and protocol
converters, soft modems, voice recognition and low end imaging, providing both large
buffer size and high processing power. Various 32-bit timers, single or dual 10-bit ADC(s),
10-bit DAC, PWM channels and 45 fast GPIO lines with up to nine edge or level sensitive
external interrupt pins make these microcontrollers suitable for industrial control and
medical systems.

NXP Semiconductors LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
6. Functional description
6.1 Architectural overview
The ARM7TDMI-S is a general purpose 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM architecture is based on
Reduced Instruction Set Computer (RISC) principles, and the instruction set and related
decode mechanism are much simpler than those of microprogrammed Complex
Instruction Set Computers (CISC). This simplicity results in a high instruction throughput
and impressive real-time interrupt response from a small and cost-effective processor
core.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM7TDMI-S processor also employs a unique architectural strategy known as
Thumb, which makes it ideally suited to high-volume applications with memory
restrictions, or applications where code density is an issue.
The key idea behind Thumb is that of a super-reduced instruction set. Essentially, the
ARM7TDMI-S processor has two instruction sets:
• The standard 32-bit ARM set.
• A 16-bit Thumb set.
The Thumb set’s 16-bit instruction length allows it to approach twice the density of
standard ARM code while retaining most of the ARM’s performance advantage over a
traditional 16-bit processor using 16-bit registers. This is possible because Thumb code
operates on the same 32-bit register set as ARM code.
Thumb code is able to provide up to 65 % of the code size of ARM, and 160 % of the
performance of an equivalent ARM processor connected to a 16-bit memory system.
The particular flash implementation in the LPC2141/42/44/46/48 allows for full speed
execution also in ARM mode. It is recommended to program performance critical and
short code sections (such as interrupt service routines and DSP algorithms) in ARM
mode. The impact on the overall code size will be minimal but the speed can be increased
by 30 % over Thumb mode.
6.2 On-chip flash program memory
The LPC2141/42/44/46/48 incorporate a 32 kB, 64 kB, 128 kB, 256 kB and 512 kB flash
memory system respectively. This memory may be used for both code and data storage.
Programming of the flash memory may be accomplished in several ways. It may be
programmed In System via the serial port. The application program may also erase and/or
program the flash while the application is running, allowing a great degree of flexibility for
data storage field firmware upgrades, etc. Due to the architectural solution chosen for an
on-chip boot loader, flash memory available for user’s code on LPC2141/42/44/46/48 is
32 kB, 64 kB, 128 kB, 256 kB and 500 kB respectively.
The LPC2141/42/44/46/48 flash memory provides a minimum of 100000 erase/write
cycles and 20 years of data-retention.

6.3 On-chip static RAM
On-chip static RAM may be used for code and/or data storage. The SRAM may be
accessed as 8-bit, 16-bit, and 32-bit. The LPC2141, LPC2142/44 and LPC2146/48
provide 8 kB, 16 kB and 32 kB of static RAM respectively.
In case of LPC2146/48 only, an 8 kB SRAM block intended to be utilized mainly by the
USB can also be used as a general purpose RAM for data storage and code storage and
execution.
6.4 Memory map
The LPC2141/42/44/46/48 memory map incorporates several distinct regions, as shown
in Figure 5.
In addition, the CPU interrupt vectors may be remapped to allow them to reside in either
flash memory (the default) or on-chip static RAM. This is described in Section 6.19
“System control”.

NXP Semiconductors LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
6.5 Interrupt controller
The Vectored Interrupt Controller (VIC) accepts all of the interrupt request inputs and
categorizes them as Fast Interrupt reQuest (FIQ), vectored Interrupt ReQuest (IRQ), and
non-vectored IRQ as defined by programmable settings. The programmable assignment
scheme means that priorities of interrupts from the various peripherals can be dynamically
assigned and adjusted.
FIQ has the highest priority. If more than one request is assigned to FIQ, the VIC
combines the requests to produce the FIQ signal to the ARM processor. The fastest
possible FIQ latency is achieved when only one request is classified as FIQ, because then
the FIQ service routine does not need to branch into the interrupt service routine but can
run from the interrupt vector location. If more than one request is assigned to the FIQ
class, the FIQ service routine will read a word from the VIC that identifies which FIQ
source(s) is (are) requesting an interrupt.
Vectored IRQs have the middle priority. Sixteen of the interrupt requests can be assigned
to this category. Any of the interrupt requests can be assigned to any of the 16 vectored
IRQ slots, among which slot 0 has the highest priority and slot 15 has the lowest.
Non-vectored IRQs have the lowest priority.
The VIC combines the requests from all the vectored and non-vectored IRQs to produce
the IRQ signal to the ARM processor. The IRQ service routine can start by reading a
register from the VIC and jumping there. If any of the vectored IRQs are pending, the VIC
provides the address of the highest-priority requesting IRQs service routine, otherwise it
provides the address of a default routine that is shared by all the non-vectored IRQs. The
default routine can read another VIC register to see what IRQs are active.
6.5.1 Interrupt sources
Each peripheral device has one interrupt line connected to the Vectored Interrupt
Controller, but may have several internal interrupt flags. Individual interrupt flags may also
represent more than one interrupt source.
6.6 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on chip peripherals. Peripherals should be connected to the appropriate pins
prior to being activated, and prior to any related interrupt(s) being enabled. Activity of any
enabled peripheral function that is not mapped to a related pin should be considered
undefined.
The Pin Control Module with its pin select registers defines the functionality of the
microcontroller in a given hardware environment.
After reset all pins of Port 0 and Port 1 are configured as input with the following
exceptions: If debug is enabled, the JTAG pins will assume their JTAG functionality; if
trace is enabled, the Trace pins will assume their trace functionality. The pins associated
with the I2C0 and I2C1 interface are open drain.

The LPC2141/42 contain one and the LPC2144/46/48 contain two analog to digital
converters. These converters are single 10-bit successive approximation analog to digital
converters. While ADC0 has six channels, ADC1 has eight channels. Therefore, total
number of available ADC inputs for LPC2141/42 is 6 and for LPC2144/46/48 is 14.
6.8.1 Features

NXP Semiconductors LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
• Selectable speed versus power.
6.10 USB 2.0 device controller
The USB is a 4-wire serial bus that supports communication between a host and a
number (127 max) of peripherals. The host controller allocates the USB bandwidth to
attached devices through a token based protocol. The bus supports hot plugging,
unplugging, and dynamic configuration of the devices. All transactions are initiated by the
host controller.
The LPC2141/42/44/46/48 is equipped with a USB device controller that enables
12 Mbit/s data exchange with a USB host controller. It consists of a register interface,
serial interface engine, endpoint buffer memory and DMA controller. The serial interface
engine decodes the USB data stream and writes data to the appropriate end point buffer
memory. The status of a completed USB transfer or error condition is indicated via status
registers. An interrupt is also generated if enabled.
A DMA controller (available in LPC2146/48 only) can transfer data between an endpoint
buffer and the USB RAM.
6.10.1 Features
• Fully compliant with USB 2.0 Full-speed specification.

software at run time.
• RAM message buffer size based on endpoint realization and maximum packet size.
• Supports SoftConnect and GoodLink LED indicator. These two functions are sharing
one pin.
• Supports bus-powered capability with low suspend current.
• Supports DMA transfer on all non-control endpoints (LPC2146/48 only).
• One duplex DMA channel serves all endpoints (LPC2146/48 only).
• Allows dynamic switching between CPU controlled and DMA modes (only in
LPC2146/48).
• Double buffer implementation for bulk and isochronous endpoints.
6.11 UARTs
The LPC2141/42/44/46/48 each contain two UARTs. In addition to standard transmit and
receive data lines, the LPC2144/46/48 UART1 also provides a full modem control
handshake interface.
Compared to previous LPC2000 microcontrollers, UARTs in LPC2141/42/44/46/48
introduce a fractional baud rate generator for both UARTs, enabling these microcontrollers
to achieve standard baud rates such as 115200 with any crystal frequency above 2 MHz.
In addition, auto-CTS/RTS flow-control functions are fully implemented in hardware
(UART1 in LPC2144/46/48 only).

6.12 I2C-bus serial I/O controller
The LPC2141/42/44/46/48 each contain two I2C-bus controllers.
The I2C-bus is bidirectional, for inter-IC control using only two wires: a Serial Clock Line
(SCL), and a Serial DAta line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver or a transmitter with the
capability to both receive and send information (such as memory)). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C-bus is a multi-master bus, it can be
controlled by more than one bus master connected to it.
The I2C-bus implemented in LPC2141/42/44/46/48 supports bit rates up to 400 kbit/s
(Fast I2C-bus).
6.12.1 Features
• Compliant with standard I2C-bus interface.
• Easy to configure as master, slave, or master/slave.
• Programmable clocks allow versatile rate control.
• Bidirectional data transfer between masters and slaves.
• Multi-master bus (no central master).
• Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
• Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
• Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
• The I2C-bus can be used for test and diagnostic purposes.
6.13 SPI serial I/O controller
The LPC2141/42/44/46/48 each contain one SPI controller. The SPI is a full duplex serial
interface, designed to handle multiple masters and slaves connected to a given bus. Only
a single master and a single slave can communicate on the interface during a given data
transfer. During a data transfer the master always sends a byte of data to the slave, and
the slave always sends a byte of data to the master.

6.13.1 Features
• Compliant with SPI specification.
• Synchronous, Serial, Full Duplex, Communication.
• Combined SPI master and slave.
• Maximum data bit rate of one eighth of the input clock rate.
6.14 SSP serial I/O controller
The LPC2141/42/44/46/48 each contain one Serial Synchronous Port controller (SSP).
The SSP controller is capable of operation on a SPI, 4-wire SSI, or Microwire bus. It can
interact with multiple masters and slaves on the bus. However, only a single master and a
single slave can communicate on the bus during a given data transfer. The SSP supports
full duplex transfers, with data frames of 4 bits to 16 bits of data flowing from the master to
the slave and from the slave to the master. Often only one of these data flows carries
meaningful data.
6.14.1 Features
• Compatible with Motorola’s SPI, TI’s 4-wire SSI and National Semiconductor’s
Microwire buses.
• Synchronous serial communication.
• Master or slave operation.
• 8-frame FIFOs for both transmit and receive.
• Four bits to 16 bits per frame.
6.15 General purpose timers/external event counters
The Timer/Counter is designed to count cycles of the peripheral clock (PCLK) or an
externally supplied clock and optionally generate interrupts or perform other actions at
specified timer values, based on four match registers. It also includes four capture inputs
to trap the timer value when an input signal transitions, optionally generating an interrupt.
Multiple pins can be selected to perform a single capture or match function, providing an
application with ‘or’ and ‘and’, as well as ‘broadcast’ functions among them.
The LPC2141/42/44/46/48 can count external events on one of the capture inputs if the
minimum external pulse is equal or longer than a period of the PCLK. In this configuration,
unused capture lines can be selected as regular timer capture inputs, or used as external
interrupts.
6.15.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• External event counter or timer operation.
• Four 32-bit capture channels per timer/counter that can take a snapshot of the timer
value when an input signal transitions. A capture event may also optionally generate
an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.

– Reset timer on match with optional interrupt generation.
• Four external outputs per timer/counter corresponding to match registers, with the
following capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
6.16 Watchdog timer
The purpose of the watchdog is to reset the microcontroller within a reasonable amount of
time if it enters an erroneous state. When enabled, the watchdog will generate a system
reset if the user program fails to ‘feed’ (or reload) the watchdog within a predetermined
amount of time.
6.16.1 Features
• Internally resets chip if not periodically reloaded.
• Debug mode.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect/Incomplete feed sequence causes reset/interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 32-bit timer with internal pre-scaler.
• Selectable time period from (Tcy(PCLK) 256 4) to (Tcy(PCLK) 232 4) in multiples of
Tcy(PCLK) 4.
6.17 Real-time clock
The RTC is designed to provide a set of counters to measure time when normal or idle
operating mode is selected. The RTC has been designed to use little power, making it
suitable for battery powered systems where the CPU is not running continuously (Idle
mode).
6.17.1 Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra-low power design to support battery powered systems.
• Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.
• Can use either the RTC dedicated 32 kHz oscillator input or clock derived from the
external crystal/oscillator input at XTAL1. Programmable reference clock divider
allows fine adjustment of the RTC.
• Dedicated power supply pin can be connected to a battery or the main 3.3 V.

6.18 Pulse width modulator
The PWM is based on the standard timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC2141/42/44/46/48. The timer is designed
to count cycles of the peripheral clock (PCLK) and optionally generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is also based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.
Two match registers can be used to provide a single edge controlled PWM output. One
match register (MR0) controls the PWM cycle rate, by resetting the count upon match.
The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an MR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the MR0 match register controls the PWM cycle rate. The other match registers
control the two PWM edge positions. Additional double edge controlled PWM outputs
require only two match registers each, since the repetition rate is the same for all PWM
outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
6.18.1 Features
• Seven match registers allow up to six single edge controlled or three double edge
controlled PWM outputs, or a mix of both types.
• The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go HIGH at the beginning of each cycle unless the
output is a constant LOW. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.

erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard timer if the PWM mode is not enabled.
• A 32-bit Timer/Counter with a programmable 32-bit Prescaler.
6.19 System control
6.19.1 Crystal oscillator
On-chip integrated oscillator operates with external crystal in range of 1 MHz to 25 MHz.
The oscillator output frequency is called fosc and the ARM processor clock frequency is
referred to as CCLK for purposes of rate equations, etc. fosc and CCLK are the same
value unless the PLL is running and connected. Refer to Section 6.19.2 “PLL” for
additional information.
6.19.2 PLL
The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input
frequency is multiplied up into the range of 10 MHz to 60 MHz with a Current Controlled
Oscillator (CCO). The multiplier can be an integer value from 1 to 32 (in practice, the
multiplier value cannot be higher than 6 on this family of microcontrollers due to the upper
frequency limit of the CPU). The CCO operates in the range of 156 MHz to 320 MHz, so
there is an additional divider in the loop to keep the CCO within its frequency range while
the PLL is providing the desired output frequency. The output divider may be set to divide
by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2,
it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and
bypassed following a chip reset and may be enabled by software. The program must
configure and activate the PLL, wait for the PLL to Lock, then connect to the PLL as a
clock source. The PLL settling time is 100 s.
6.19.3 Reset and wake-up timer
Reset has two sources on the LPC2141/42/44/46/48: the RESET pin and watchdog reset.
The RESET pin is a Schmitt trigger input pin with an additional glitch filter. Assertion of
chip reset by any source starts the Wake-up Timer (see Wake-up Timer description
below), causing the internal chip reset to remain asserted until the external reset is
de-asserted, the oscillator is running, a fixed number of clocks have passed, and the
on-chip flash controller has completed its initialization.
When the internal reset is removed, the processor begins executing at address 0, which is
the reset vector. At that point, all of the processor and peripheral registers have been
initialized to predetermined values.
The Wake-up Timer ensures that the oscillator and other analog functions required for
chip operation are fully functional before the processor is allowed to execute instructions.
This is important at power on, all types of reset, and whenever any of the aforementioned
functions are turned off for any reason. Since the oscillator and other functions are turned
off during Power-down mode, any wake-up of the processor from Power-down mode
makes use of the Wake-up Timer.

NXP Semiconductors LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
The Wake-up Timer monitors the crystal oscillator as the means of checking whether it is
safe to begin code execution. When power is applied to the chip, or some event caused
the chip to exit Power-down mode, some time is required for the oscillator to produce a
signal of sufficient amplitude to drive the clock logic. The amount of time depends on
many factors, including the rate of VDD ramp (in the case of power on), the type of crystal
and its electrical characteristics (if a quartz crystal is used), as well as any other external
circuitry (e.g. capacitors), and the characteristics of the oscillator itself under the existing
ambient conditions.
6.19.4 Brownout detector
The LPC2141/42/44/46/48 include 2-stage monitoring of the voltage on the VDD pins. If
this voltage falls below 2.9 V, the BOD asserts an interrupt signal to the VIC. This signal
can be enabled for interrupt; if not, software can monitor the signal by reading dedicated
register.
The second stage of low voltage detection asserts reset to inactivate the
LPC2141/42/44/46/48 when the voltage on the VDD pins falls below 2.6 V. This reset
prevents alteration of the flash as operation of the various elements of the chip would
otherwise become unreliable due to low voltage. The BOD circuit maintains this reset
down below 1 V, at which point the POR circuitry maintains the overall reset.
Both the 2.9 V and 2.6 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.9 V detection to reliably interrupt, or a regularly-executed event
loop to sense the condition.
6.19.5 Code security
This feature of the LPC2141/42/44/46/48 allow an application to control whether it can be
debugged or protected from observation.
If after reset on-chip boot loader detects a valid checksum in flash and reads 0x8765 4321
from address 0x1FC in flash, debugging will be disabled and thus the code in flash will be
protected from observation. Once debugging is disabled, it can be enabled only by
performing a full chip erase using the ISP.
6.19.6 External interrupt inputs
The LPC2141/42/44/46/48 include up to nine edge or level sensitive External Interrupt
Inputs as selectable pin functions. When the pins are combined, external events can be
processed as four independent interrupt signals. The External Interrupt Inputs can
optionally be used to wake-up the processor from Power-down mode.
Additionally capture input pins can also be used as external interrupts without the option
to wake the device up from Power-down mode.
6.19.7 Memory mapping control
The Memory Mapping Control alters the mapping of the interrupt vectors that appear
beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the on-chip
flash memory, or to the on-chip static RAM. This allows code running in different memory
spaces to have control of the interrupts.

Single-chip 16-bit/32-bit microcontrollers
6.19.8 Power control
The LPC2141/42/44/46/48 supports two reduced power modes: Idle mode and
Power-down mode.
In Idle mode, execution of instructions is suspended until either a reset or interrupt occurs.
Peripheral functions continue operation during Idle mode and may generate interrupts to
cause the processor to resume execution. Idle mode eliminates power used by the
processor itself, memory systems and related controllers, and internal buses.
In Power-down mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Power-down mode and the logic levels of chip output pins remain
static. The Power-down mode can be terminated and normal operation resumed by either
a reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Power-down mode reduces chip power
consumption to nearly zero.
Selecting an external 32 kHz clock instead of the PCLK as a clock-source for the on-chip
RTC will enable the microcontroller to have the RTC active during Power-down mode.
Power-down current is increased with RTC active. However, it is significantly lower than in
Idle mode.
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings during active
and Idle mode.
6.19.9 APB bus
The APB divider determines the relationship between the processor clock (CCLK) and the
clock used by peripheral devices (PCLK). The APB divider serves two purposes. The first
is to provide peripherals with the desired PCLK via APB bus so that they can operate at
the speed chosen for the ARM processor. In order to achieve this, the APB bus may be
slowed down to 12 to 14 of the processor clock rate. Because the APB bus must work
properly at power-up (and its timing cannot be altered if it does not work since the APB
divider control registers reside on the APB bus), the default condition at reset is for the
APB bus to run at 14 of the processor clock rate. The second purpose of the APB divider
is to allow power savings when an application does not require any peripherals to run at
the full processor rate. Because the APB divider is connected to the PLL output, the PLL
remains active (if it was running) during Idle mode.
6.20 Emulation and debugging
The LPC2141/42/44/46/48 support emulation and debugging via a JTAG serial port. A
trace port allows tracing program execution. Debugging and trace functions are
multiplexed only with GPIOs on Port 1. This means that all communication, timer and
interface peripherals residing on Port 0 are available during the development and
debugging phase as they are when the application is run in the embedded system itself.
6.20.1 EmbeddedICE
Standard ARM EmbeddedICE logic provides on-chip debug support. The debugging of
the target system requires a host computer running the debugger software and an
EmbeddedICE protocol convertor. EmbeddedICE protocol convertor converts the remote
debug protocol commands to the JTAG data needed to access the ARM core.

NXP Semiconductors LPC2141/42/44/46/48
Single-chip 16-bit/32-bit microcontrollers
The ARM core has a Debug Communication Channel (DCC) function built-in. The DCC
allows a program running on the target to communicate with the host debugger or another
separate host without stopping the program flow or even entering the debug state. The
DCC is accessed as a co-processor 14 by the program running on the ARM7TDMI-S
core. The DCC allows the JTAG port to be used for sending and receiving data without
affecting the normal program flow. The DCC data and control registers are mapped in to
addresses in the EmbeddedICE logic.
This clock must be slower than 16 of the CPU clock (CCLK) for the JTAG interface to
operate.
6.20.2 Embedded trace
Since the LPC2141/42/44/46/48 have significant amounts of on-chip memory, it is not
possible to determine how the processor core is operating simply by observing the
external pins. The Embedded Trace Macrocell (ETM) provides real-time trace capability
for deeply embedded processor cores. It outputs information about processor execution to
the trace port.
The ETM is connected directly to the ARM core and not to the main AMBA system bus. It
compresses the trace information and exports it through a narrow trace port. An external
trace port analyzer must capture the trace information under software debugger control.
Instruction trace (or PC trace) shows the flow of execution of the processor and provides a
list of all the instructions that were executed. Instruction trace is significantly compressed
by only broadcasting branch addresses as well as a set of status signals that indicate the
pipeline status on a cycle by cycle basis. Trace information generation can be controlled
by selecting the trigger resource. Trigger resources include address comparators,
counters and sequencers. Since trace information is compressed the software debugger
requires a static image of the code being executed. Self-modifying code can not be traced
because of this restriction.
6.20.3 RealMonitor
RealMonitor is a configurable software module, developed by ARM Inc., which enables
real-time debug. It is a lightweight debug monitor that runs in the background while users
debug their foreground application. It communicates with the host using the DCC, which is
present in the EmbeddedICE logic. The LPC2141/42/44/46/48 contain a specific
configuration of RealMonitor software programmed into the on-chip flash memory.

= 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci
/ (Ci
+ Cg). In
slave mode, a minimum of 200 mV (RMS) is needed.
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(Figure 20), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This
corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V.
The XTAL2 pin in this configuration can be left unconnected.
External components and models used in oscillation mode are shown in Figure 21 and in
Table 16 and Table 17. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances CX1 and CX2 need to be connected externally in case of
fundamental mode oscillation (the fundamental frequency is represented by L, CL and
RS). Capacitance CP in Figure 21 represents the parallel package capacitance and should
not be larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal
manufacturer.

14.3 RTC 32 kHz oscillator component selection
The RTC external oscillator circuit is shown in Figure 22. Since the feedback resistance is
integrated on chip, only a crystal, the capacitances CX1 and CX2 need to be connected
externally to the microcontroller.
Table 18 gives the crystal parameters that should be used. CL is the typical load
capacitance of the crystal and is usually specified by the crystal manufacturer. The actual
CL influences oscillation frequency. When using a crystal that is manufactured for a
different load capacitance, the circuit will oscillate at a slightly different frequency
(depending on the quality of the crystal) compared to the specified one. Therefore for an
accurate time reference it is advised to use the load capacitors as specified in Table 18
that belong to a specific CL. The value of external capacitances CX1 and CX2 specified in
this table are calculated from the internal parasitic capacitances and the CL. Parasitics
from PCB and package are not taken into account.
14.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines
The crystal should be connected on the PCB as close as possible to the oscillator input
and output pins of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of
third overtone crystal usage have a common ground plane. The external components
must also be connected to the ground plain. Loops must be made as small as possible in
order to keep the noise coupled in via the PCB as small as possible. Also parasitics
should stay as small as possible. Values of Cx1 and Cx2 should be chosen smaller
accordingly to the increase in parasitics of the PCB layout.

Description
The FSDM0565RB is an integrated Pulse Width Modulator
(PWM) and Sense FET specifically designed for high
performance offline Switch Mode Power Supplies (SMPS)
with minimal external components. This device is an
integrated high voltage power switching regulator which
combine an avalanche rugged Sense FET with a current mode
PWM control block. The PWM controller includes integrated
fixed frequency oscillator, under voltage lockout, leading edge
blanking (LEB), optimized gate driver, internal soft start,
temperature compensated precise current sources for a loop
compensation and self protection circuitry. Compared with
discrete MOSFET and PWM controller solution, it can reduce
total cost, component count, size and weight simultaneously
increasing efficiency, productivity, and system reliability. This
device is a basic platform well suited for cost effective
designs of flyback converters.

Pin Definitions
Pin Configuration
Figure 3. Pin Configuration (Top View)
Pin Number Pin Name Pin Function Description
1 Drain This pin is the high voltage power Sense FET drain. It is designed to drive the
transformer directly.
2 GND This pin is the control ground and the Sense FET source.
3 Vcc
This pin is the positive supply voltage input. During start up, the power is supplied
by an internal high voltage current source that is connected to the Vstr pin.
When Vcc reaches 12V, the internal high voltage current source is disabled and
the power is supplied from the auxiliary transformer winding.
4 Vfb
This pin is internally connected to the inverting input of the PWM comparator.
The collector of an opto-coupler is typically tied to this pin. For stable operation,
a capacitor should be placed between this pin and GND. If the voltage of this pin
reaches 6.0V, the over load protection is activated resulting in shutdown of the
FPSTM.
5 N.C -
6 Vstr
This pin is connected directly to the high voltage DC link. At startup, the internal
high voltage current source supplies internal bias and charges the external capacitor
that is connected to the Vcc pin. Once Vcc reaches 12V, the internal current
source is disabled.

Functional Description
1. Startup : In previous generations of Fairchild Power
Switches (FPSTM) the Vcc pin had an external start-up
resistor to the DC input voltage line. In this generation the
startup resistor is replaced by an internal high voltage current
source. At startup, an internal high voltage current source
supplies the internal bias and charges the external capacitor
(Cvcc) that is connected to the Vcc pin as illustrated in
Figure 4. When Vcc reaches 12V, the FSDM0565RB begins
switching and the internal high voltage current source is
disabled. Then, the FSDM0565RB continues its normal
switching operation and the power is supplied from the
auxiliary transformer winding unless Vcc goes below the
stop voltage of 8V.
Figure 4. Internal startup circuit
2. Feedback Control : FSDM0565RB employs current
mode control, as shown in Figure 5. An opto-coupler (such
as the H11A817A) and shunt regulator (such as the KA431)
are typically used to implement the feedback network.
Comparing the feedback voltage with the voltage across the
Rsense resistor plus an offset voltage makes it possible to
control the switching duty cycle. When the reference pin
voltage of the KA431 exceeds the internal reference voltage
of 2.5V, the H11A817A LED current increases, thus pulling
down the feedback voltage and reducing the duty cycle. This
event typically happens when the input voltage is increased
or the output load is decreased.
2.1 Pulse-by-pulse current limit: Because current mode
control is employed, the peak current through the Sense FET
is limited by the inverting input of PWM comparator (Vfb*)
as shown in Figure 5. Assuming that the 0.9mA current
source flows only through the internal resistor (2.5R +R= 2.8
kΩ), the cathode voltage of diode D2 is about 2.5V. Since D1
is blocked when the feedback voltage (Vfb) exceeds 2.5V,
the maximum voltage of the cathode of D2 is clamped at this
voltage, thus clamping Vfb*. Therefore, the peak value of
the current through the Sense FET is limited.
2.2 Leading edge blanking (LEB) : At the instant the
internal Sense FET is turned on, there usually exists a high
current spike through the Sense FET, caused by primary-side
capacitance and secondary-side rectifier reverse recovery.
Excessive voltage across the Rsense resistor would lead to
incorrect feedback operation in the current mode PWM
control. To counter this effect, the FSDM0565RB employs a
leading edge blanking (LEB) circuit. This circuit inhibits the
PWM comparator for a short time (TLEB) after the Sense
FET is turned on.
Figure 5. Pulse width modulation (PWM) circuit
3. Protection Circuit : The FSDM0565RB has several self
protective functions such as over load protection (OLP), over
voltage protection (OVP) and thermal shutdown (TSD).
Because these protection circuits are fully integrated into the
IC without external components, the reliability can be
improved without increasing cost. Once the fault condition
occurs, switching is terminated and the Sense FET remains
off. This causes Vcc to fall. When Vcc reaches the UVLO
stop voltage, 8V, the protection is reset and the internal high
voltage current source charges the Vcc capacitor via the Vstr
pin. When Vcc reaches the UVLO start voltage,12V, the
FSDM0565RB resumes its normal operation. In this manner,
the auto-restart can alternately enable and disable the
switching of the power Sense FET until the fault condition is
eliminated (see Figure 6).

3.1 Over Load Protection (OLP) : Overload is defined as
the load current exceeding a pre-set level due to an
unexpected event. In this situation, the protection circuit
should be activated in order to protect the SMPS. However,
even when the SMPS is in the normal operation, the over
load protection circuit can be activated during the load
transition. In order to avoid this undesired operation, the over
load protection circuit is designed to be activated after a
specified time to determine whether it is a transient situation
or an overload situation. Because of the pulse-by-pulse
current limit capability, the maximum peak current through
the Sense FET is limited, and therefore the maximum input
power is restricted with a given input voltage. If the output
consumes beyond this maximum power, the output voltage
(Vo) decreases below the set voltage. This reduces the
current through the opto-coupler LED, which also reduces
the opto-coupler transistor current, thus increasing the
feedback voltage (Vfb). If Vfb exceeds 2.5V, D1 is blocked
and the 3.5uA current source starts to charge CB slowly up to
Vcc. In this condition, Vfb continues increasing until it
reaches 6V, when the switching operation is terminated as
shown in Figure 7. The delay time for shutdown is the time
required to charge CB from 2.5V to 6.0V with 3.5uA. In
general, a 10 ~ 50 ms delay time is typical for most
applications.
Figure 7. Over load protection
3.2 Over voltage Protection (OVP) : If the secondary side
feedback circuit were to malfunction or a solder defect
caused an open in the feedback path, the current through the
opto-coupler transistor becomes almost zero. Then, Vfb
climbs up in a similar manner to the over load situation,
forcing the preset maximum current to be supplied to the
SMPS until the over load protection is activated. Because
more energy than required is provided to the output, the
output voltage may exceed the rated voltage before the over
load protection is activated, resulting in the breakdown of the
devices in the secondary side. In order to prevent this
situation, an over voltage protection (OVP) circuit is
employed. In general, Vcc is proportional to the output
voltage and the FSDM0565RB uses Vcc instead of directly
monitoring the output voltage. If VCC exceeds 19V, an OVP
circuit is activated resulting in the termination of the
switching operation. In order to avoid undesired activation of
OVP during normal operation, Vcc should be designed to be
below 19V.
3.3 Thermal Shutdown (TSD) : The Sense FET and the
control IC are built in one package. This makes it easy for
the control IC to detect the heat generation from the Sense
FET. When the temperature exceeds approximately 150°C,
the thermal shutdown is activated.
4. Soft Start : The FSDM0565RB has an internal soft start
circuit that increases PWM comparator inverting input
voltage together with the Sense FET current slowly after it
starts up. The typical soft start time is 10msec, The pulse
width to the power switching device is progressively
increased to establish the correct working conditions for
transformers, inductors, and capacitors. The voltage on the
output capacitors is progressively increased with the
intention of smoothly establishing the required output
voltage. It also helps to prevent transformer saturation and
reduce the stress on the secondary diode during startup.

5. Burst operation : In order to minimize power dissipation
in standby mode, the FSDM0565RB enters burst mode
operation. As the load decreases, the feedback voltage
decreases. As shown in Figure 8, the device automatically
enters burst mode when the feedback voltage drops below
VBURL(500mV). At this point switching stops and the
output voltages start to drop at a rate dependent on standby
current load. This causes the feedback voltage to rise. Once
it passes VBURH(700mV) switching resumes. The feedback
voltage then falls and the process repeats. Burst mode
operation alternately enables and disables switching of the
power Sense FET thereby reducing switching loss in
Standby mode.

Typical application circuit
Features
• High efficiency (>81% at 85Vac input)
• Low zero load power consumption (<300mW at 240Vac input)
• Low standby mode power consumption (<800mW at 240Vac input and 0.3W load)
• Low component count
• Enhanced system reliability through various protection functions
• Internal soft-start (10ms)
Key Design Notes
• Resistors R102 and R105 are employed to prevent start-up at low input voltage. After startup, there is no power loss in these
resistors since the startup pin is internally disconnected after startup.
• The delay time for over load protection is designed to be about 50ms with C106 of 47nF. If a faster triggering of OLP is
required, C106 can be reduced to 10nF.
• Zener diode ZD102 is used for a safety test such as UL. When the drain pin and feedback pin are shorted, the zener diode
fails and remains short, which causes the fuse (F1) blown and prevents explosion of the opto-coupler (IC301). This zener
diode also increases the immunity against line surge.

1 Introduction
The JN5148-001 is an IEEE802.15.4 wireless microcontroller that provides a fully integrated solution for applications
using the IEEE802.15.4 standard in the 2.4 - 2.5GHz ISM frequency band [1], including JenNet and ZigBee PRO. It
includes all of the functionality required to meet the IEEE802.15.4, JenNet and ZigBee PRO specifications and has
additional processor capability to run a wide range of applications including, but not limited to Smart Energy,
Automatic Meter Reading, Remote Control, Home and Building Automation, Toys and Gaming.
Applications that transfer data wirelessly tend to be more complex than wired ones. Wireless protocols make
stringent demands on frequencies, data formats, timing of data transfers, security and other issues. Application
development must consider the requirements of the wireless network in addition to the product functionality and user
interfaces. To minimise this complexity, NXP provides a series of software libraries and interfaces that control the
transceiver and peripherals of the JN5148. These libraries and interfaces remove the need for the developer to
understand wireless protocols and greatly simplifies the programming complexities of power modes, interrupts and
hardware functionality.
In view of the above, the register details of the JN5148 are not provided in the datasheet.
The device includes a Wireless Transceiver, RISC CPU, on chip memory and an extensive range of peripherals.
Hereafter, the JN5148-001 will be referred to as JN5148.
1.1 Wireless Transceiver
The Wireless Transceiver comprises a 2.45GHz radio, a modem, a baseband controller and a security coprocessor.
In addition, the radio also provides an output to control transmit-receive switching of external devices such as power
amplifiers allowing applications that require increased transmit power to be realised very easily. Appendix B.4,
describes a complete reference design including Printed Circuit Board (PCB) design and Bill Of Materials (BOM).
The security coprocessor provides hardware-based 128-bit AES-CCM* modes as specified by the IEEE802.15.4
2006 standard. Specifically this includes encryption and authentication covered by the MIC –32/ -64/ -128, ENC and
ENC-MIC –32/ -64/ -128 modes of operation.
The transceiver elements (radio, modem and baseband) work together to provide IEEE802.15.4 Medium Access
Control (MAC) under the control of a protocol stack. Applications incorporating IEEE802.15.4 functionality can be
rapidly developed by combining user-developed application software with a protocol stack library.
1.2 RISC CPU and Memory
A 32-bit RISC CPU allows software to be run on chip, its processing power being shared between the IEEE802.15.4
MAC protocol, other higher layer protocols and the user application. The JN5148 has a unified memory architecture,
code memory, data memory, peripheral devices and I/O ports are organised within the same linear address space.
The device contains 128kbytes of ROM, 128kbytes of RAM and a 32-byte One Time Programmable (OTP) eFuse
memory. © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 7
1.3 Peripherals

The PCB schematic and layout rules detailed in Appendix B.4
must be followed. Failure to do so will likely result in the
JN5148 failing to meet the performance specification detailed
herein and worst case may result in device not functioning in
the end application.12 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
2.2 Pin Descriptions
2.2.1 Power Supplies
The device is powered from the VDD1 and VDD2 pins, each being decoupled with a 100nF ceramic capacitor. VDD1
is the power supply to the analogue circuitry; it should be decoupled to ground. VDD2 is the power supply for the
digital circuitry; and should also be decoupled to ground. A 10uF tantalum capacitor is required. Decoupling pins for
the internal 1.8V regulators are provided which require a 100nF capacitor located as close to the device as practical.
VB_RF, VB_A and VB_SYNTH should be decoupled with an additional 47pF capacitor, while VB_RAM and VB_DIG
require only 100nF. VB_RF and VB_RF2 should be connected together as close to the device as practical, and only
require one 100nF capacitor and one 47pF capacitor. The pin VB_VCO requires a 10nF capacitor in parallel with a
47pF capacitor. Refer to B.4.1 for schematic diagram.
VSSA, VSSS, VSS1, VSS2, VSS3 are the ground pins.
Users are strongly discouraged from connecting their own circuits to the 1.8v regulated supply pins, as the regulators
have been optimised to supply only enough current for the internal circuits.
2.2.2 Reset
RESETN is a bi-directional active low reset pin that is connected to a 40kΩ internal pull-up resistor. It may be pulled
low by an external circuit, or can be driven low by the JN5148 if an internal reset is generated. Typically, it will be
used to provide a system reset signal. Refer to section 6.2, External Reset, for more details.
2.2.3 32MHz Oscillator
A crystal is connected between XTALIN and XTALOUT to form the reference oscillator, which drives the system
clock. A capacitor to analogue ground is required on each of these pins. Refer to section 5.1 16MHz System Clock
for more details. The 32MHz reference frequency is divided down to 16MHz and this is used as the system clock
throughout the device.
2.2.4 Radio
The radio is a single ended design, requiring a capacitor and just two inductors to match to 50Ω microstrip line to the
RF_IN pin.
An external resistor (43kΩ) is required between IBIAS and analogue ground to set various bias currents and
references within the radio.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 13
2.2.5 Analogue Peripherals
Several of the analogue peripherals require a reference voltage to use as part of their operations. They can use
either an internal reference voltage or an external reference connected to VREF. This voltage is referenced to
analogue ground and the performance of the analogue peripherals is dependant on the quality of this reference.
There are four ADC inputs, two pairs of comparator inputs and two DAC outputs. The analogue I/O pins on the
JN5148 can have signals applied up to 0.3v higher than VDD1. A schematic view of the analogue I/O cell is shown in
Figure 3: Analogue I/O Cell
In reset and deep sleep, the analogue peripherals are all off and the DAC outputs are in a high impedance state.
In sleep, the ADC and DACs are off, with the DAC outputs in high impedance state. The comparators may optionally
be used as a wakeup source.
Unused ADC and comparator inputs should be left unconnected.

2.2.6 Digital Input/Output
Digital I/O pins on the JN5148 can have signals applied up to 2V higher than VDD2 (with the exception of pins DIO9
and DIO10 that are 3V tolerant) and are therefore TTL-compatible with VDD2 > 3V. For other DC properties of these
pins see section 22.2.3 I/O Characteristics.
When used in their primary function all Digital Input/Output pins are bi-directional and are connected to weak internal
pull up resistors (40kΩ nominal) that can be disabled. When used in their secondary function (selected when the
appropriate peripheral block is enabled through software library calls) then their direction is fixed by the function. The
pull up resistor is enabled or disabled independently of the function and direction; the default state from reset is
enabled.

from sleep.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 15
3 CPU
The CPU of the JN5148 is a 32-bit load and store RISC processor. It has been architected for three key
requirements:
• Low power consumption for battery powered applications
• High performance to implement a wireless protocol at the same time as complex applications
• Efficient coding of high-level languages such as C provided with the NXP Software Developer’s Kit
It features a linear 32-bit logical address space with unified memory architecture, accessing both code and data in the
same address space. Registers for peripheral units, such as the timers, UARTs and the baseband processor are
also mapped into this space.
The CPU has access to a block of 15 32-bit General-Purpose (GP) registers together with a small number of special
purpose registers which are used to store processor state and control interrupt handling. The contents of any GP
register can be loaded from or stored to memory, while arithmetic and logical operations, shift and rotate operations,
and signed and unsigned comparisons can be performed either between two registers and stored in a third, or
between registers and a constant carried in the instruction. Operations between general or special-purpose registers
execute in one cycle while those that access memory require a further cycle to allow the memory to respond.
The instruction set manipulates 8, 16 and 32-bit data; this means that programs can use objects of these sizes very
efficiently. Manipulation of 32-bit quantities is particularly useful for protocols and high-end applications allowing
algorithms to be implemented in fewer instructions than on smaller word-size processors, and to execute in fewer
clock cycles. In addition, the CPU supports hardware Multiply that can be used to efficiently implement algorithms
needed by Digital Signal Processing applications.
The instruction set is designed for the efficient implementation of high-level languages such as C. Access to fields in
complex data structures is very efficient due to the provision of several addressing modes, together with the ability to
be able to use any of the GP registers to contain the address of objects. Subroutine parameter passing is also made
more efficient by using GP registers rather than pushing objects onto the stack. The recommended programming
method for the JN5148 is by using C, which is supported by a software developer kit comprising a C compiler, linker
and debugger.
The CPU architecture also contains features that make the processor suitable for embedded, real-time applications.
In some applications, it may be necessary to use a real-time operating system to allow multiple tasks to run on the
processor. To provide protection for device-wide resources being altered by one task and affecting another, the
processor can run in either supervisor or user mode, the former allowing access to all processor registers, while the
latter only allows the GP registers to be manipulated. Supervisor mode is entered on reset or interrupt; tasks starting
up would normally run in user mode in a RTOS environment.
Embedded applications require efficient handling of external hardware events. When using JenOS, prioritised
interrupts are supported, with 15 priority levels, and can be configured as required by the application.
To improve power consumption a number of power-saving modes are implemented in the JN5148, described more
fully in section 21 - Power Management and Sleep Modes. One of these modes is the CPU doze mode; under
software control, the processor can be shut down and on an interrupt it will wake up to service the request.
Additionally, it is possible under software control, to set the speed of the CPU to 4, 8, 16 or 32MHz. This feature can
be used to trade-off processing power against current consumption.16 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

The ROM is 128k bytes in size, and can be accessed by the processor in a single CPU clock cycle. The ROM
contents include bootloader to allow external Flash memory contents to be bootloaded into RAM at runtime, a default
interrupt vector table, an interrupt manager, IEEE802.15.4 MAC and APIs for interfacing on-chip peripherals. The
operation of the boot loader is described in detail in Application Note [7]. The interrupt manager routes interrupt calls
to the application’s soft interrupt vector table contained within RAM. Section 7 contains further information regarding

4.2 RAM
The JN5148 contains 128kBytes of high speed RAM. It can be used for both code and data storage and is accessed
by the CPU in a single clock cycle. At reset, a boot loader controls the loading of segments of code and data from an
external memory connected to the SPI port, into RAM. Software can control the power supply to the RAM allowing
the contents to be maintained during a sleep period when other parts of the device are un-powered. Typical RAM
contents are shown in Figure 7.

4.3 OTP eFuse Memory
The JN5148 contains a total of 32bytes of eFuse memory; this is a One Time Programmable (OTP) memory that can
be used to support on chip 64-bit MAC ID and a 128-bit AES security key. A limited number of bits are available for
customer use for storage of configuration information; configuration of these is made through use of software APIs.
For further information on how to program and use the eFuse memory, please contact technical support via the online
tech-support system.
Alternatively, NXP can provide an eFuse programming service for customers that wish to use the eFuse but do not
wish to undertake this for themselves. For further details of this service, please contact your local NXP sales office.
4.4 External Memory
An external memory with an SPI interface may be used to provide storage for program code and data for the device
when external power is removed. The memory is connected to the SPI interface using select line SPISEL0; this
select line is dedicated to the external memory interface and is not available for use with other external devices. See
Figure 8 for connection details.

At reset, the contents of this memory are copied into RAM by the software boot loader. The Flash memory devices
that are supported as standard through the JN5148 bootloader are given in Table 1. NXP recommends that where
possible one of these devices should be selected.

Applications wishing to use an alternate Flash memory device should refer to application note [2] JN-AN-1038
Programming Flash devices not supported by the JN51xx ROM-based bootloader. This application note provides
guidance on developing an interface to an alternate device.
4.4.1 External Memory Encryption
The contents of the external serial memory may be encrypted. The AES security processor combined with a user
programmable 128-bit encryption key is used to encrypt the contents of the external memory. The encryption key is
stored in eFuse.
When bootloading program code from external serial memory, the JN5148 automatically accesses the encryption key
to execute the decryption process. User program code does not need to handle any of the decryption process; it is
transparent.
With encryption enabled, the time taken to boot code from external flash is increased.
4.5 Peripherals
All peripherals have their registers mapped into the memory space. Access to these registers requires 3 clock
cycles. Applications have access to the peripherals through the software libraries that present a high-level view of
the peripheral’s functions through a series of dedicated software routines. These routines provide both a tested
method for using the peripherals and allow bug-free application code to be developed more rapidly. For details, see
the JN51xx Integrated Peripherals API User Guide (JN-UG-3066)[5].
4.6 Unused Memory Addresses
Any attempt to access an unpopulated memory area will result in a bus error exception (interrupt) being generated.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 19
5 System Clocks
Two system clocks are used to provide timing references into the on-chip subsystems of the JN5148. A 16MHz clock,
generated by a crystal-controlled 32MHz oscillator, is used by the transceiver, processor, memory and digital and
analogue peripherals. A 32kHz clock is used by the sleep timer and during the startup phase of the chip.
5.1 16MHz System Clock
The 16MHz system clock is used by the digital and analogue peripherals and the transceiver. A scaled version
(4,8,16 or 32MHz) of this clock is also used by the processor and memories. For most operations it is necessary to
source this clock from the 32MHz oscillator.
Crystal oscillators are generally slow to start. Hence to provide a faster start-up following a sleep cycle a fast RC
oscillator is provided that can be used as the source for the 16MHz system clock. The oscillator starts very quickly
and is typically 24MHz causing the system clock to run at 12MHz. Using a clock of this speed scales down the speed
of the processor and any peripherals in use. For the SPI interface this causes no functional issues as the generated
SPI clock is slightly slower and is used to clock the external SPI slave. Use of the radio is not possible when using the
24MHz RC oscillator. Additionally, timers and UARTs should not be used as the exact frequency will not be known.
The JN5148 device can be configured to wake up from sleep using the fast RC oscillator and automatically switch
over to use the 32MHz xtal as the clock source, when it has started up. This could allow application code to be
downloaded from the flash before the xtal is ready, typically improving start-up time by 550usec. Alternatively, the
switch over can be controlled by software, or the system could always use the 32MHz oscillator as the clock source.
5.1.1 32MHz Oscillator
The JN5148 contains the necessary on chip components to build a 32MHz reference oscillator with the addition of an
external crystal resonator and two tuning capacitors. The schematic of these components are shown in Figure 9.
The two capacitors, C1 and C2, should typically be 15pF and use a COG dielectric. Due to the small size of these
capacitors, it is important to keep the traces to the external components as short as possible. The on chip
transconductance amplifier is compensated for temperature variation, and is self-biasing by means of the internal
resistor R1. The electrical specification of the oscillator can be found in section 22.3.13. Please refer to Appendix B
for development support with the crystal oscillator circuit.

5.1.2 24MHz RC Oscillator
An on-chip 24MHz RC oscillator is provided. No external components are required for this oscillator. The electrical
specification of the oscillator can be found in section 22.3.14.20 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
5.2 32kHz System Clock
The 32kHz system clock is used for timing the length of a sleep period (see section 21 Power Management and
Sleep Modes) and also to generate the system clock used internally during reset. The clock can be selected from
one of three sources through the application software:
• 32kHz RC Oscillator
• 32kHz Crystal Oscillator
• 32kHz External Clock
Upon a chip reset or power-up the JN5148 defaults to using the internal 32kHz RC Oscillator. If another clock source
is selected then it will remain in use for all 32kHz timing until a chip reset is performed.
5.2.1 32kHz RC Oscillator
The internal 32kHz RC oscillator requires no external components. The internal timing components of the oscillator
have a wide tolerance due to manufacturing process variation and so the oscillator runs nominally at 32kHz ±30%. To
make this useful as a timing source for accurate wakeup from sleep, a frequency calibration factor derived from the
more accurate 16MHz clock may be applied. The calibration factor is derived through software, details can be found
in section 11.3.1. For detailed electrical specifications, see section 22.3.11.
5.2.2 32kHz Crystal Oscillator
In order to obtain more accurate sleep periods, the JN5148 contains the necessary on-chip components to build a
32kHz oscillator with the addition of an external 32.768kHz crystal and two tuning capacitors. The crystal should be
connected between 32KXTALIN and 32KXTALOUT (DIO9 and DIO10), with two equal capacitors to ground, one on
each pin. Due to the small size of the capacitors, it is important to keep the traces to the external components as
short as possible.
The electrical specification of the oscillator can be found in section 22.3.12. The oscillator cell is flexible and can
operate with a range of commonly available 32.768kHz crystals with load capacitances from 6 to 12.5pF. However,
the maximum ESR of the crystal and the supply current are both functions of the actual crystal used, see appendix
B.1 for more details.

Figure 10: 32kHz crystal oscillator connections
5.2.3 32kHz External Clock
An externally supplied 32kHz reference clock on the 32KIN input (DIO9) may be provided to the JN5148. This would
allow the 32kHz system clock to be sourced from a very stable external oscillator module, allowing more accurate
sleep cycle timings compared to the internal RC oscillator. (See section 22.2.3 I/O Characteristics, DIO9 is a 3V
tolerant input)© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 21
6 Reset
A system reset initialises the device to a pre-defined state and forces the CPU to start program execution from the
reset vector. The reset process that the JN5148 goes through is as follows.
When power is applied, the 32kHz RC oscillator starts up and stabilises, which takes approximately 100µsec. At this
point, the 32MHz crystal oscillator is enabled and power is applied to the processor and peripheral logic. The logic
blocks are held in reset until the 32MHz crystal oscillator stabilises, typically this takes 0.75ms. Then the internal
reset is removed from the CPU and peripheral logic and the CPU starts to run code beginning at the reset vector,
consisting of initialisation code and the resident boot loader. [7] Section 22.3.1 provides detailed electrical data and
timing.
The JN5148 has five sources of reset:
• Internal Power-on Reset
• External Reset
• Software Reset
• Watchdog timer
• Brown-out detect
Note: When the device exits a reset condition, device operating
parameters (voltage, frequency, temperature, etc.) must be met to ensure
operation. If these conditions are not met, then the device must be held in
reset until the operating conditions are met. (See section 22.3)
6.1 Internal Power-on Reset
For the majority of applications the internal power-on reset is capable of generating the required reset signal. When
power is applied to the device, the power-on reset circuit monitors the rise of the VDD supply. When the VDD
reaches the specified threshold, the reset signal is generated and can be observed as a rising edge on the RESETN
pin. This signal is held internally until the power supply and oscillator stabilisation time has elapsed, when the internal
reset signal is then removed and the CPU is allowed to run.

When the supply drops below the power on reset ‘falling’ threshold, it will re-trigger the reset. Use of the external

Figure 12: External Reset Generation
The external resistor and capacitor provide a simple reset operation when connected to the RESETN pin.
6.2 External Reset
An external reset is generated by a low level on the RESETN pin. Reset pulses longer than the minimum pulse width
will generate a reset during active or sleep modes. Shorter pulses are not guaranteed to generate a reset. The
JN5148 is held in reset while the RESETN pin is low. When the applied signal reaches the Reset Threshold Voltage
(VRST) on its positive edge, the internal reset process starts.
Multiple devices may connect to the RESETN pin in an open-collector mode. The JN5148 has an internal pull-up
resistor connect to the RESETN pin. The pin is an input for an external reset, an output during the power-on reset
and may optionally be an output during a software reset. No devices should drive the RESETN pin high.

Figure 13: External Reset
6.3 Software Reset
A system reset can be triggered at any time through software control, causing a full chip reset and invalidating the
RAM contents. For example this can be executed within a user’s application upon detection of a system failure. When
performing the reset, the RESETN pin is driven low for 1µsec; depending on the external components this may or
may not be visible on the pin.
In addition, the RESETN line can be driven low by the JN5148 to provide a reset to other devices in the system (e.g.
external sensors) without resetting itself. When the RESETN line is not driven it will pull back high through either the
internal pull-up resistor or any external circuitry. It is essential to ensure that the RESETN line pulls back high within
100µsec after the JN5148 stops driving the line; otherwise a system reset will occur. Due to this, careful consideration
should be taken of any capacitance on this line. For instance, the RC values recommended in section 6.1 may need
to be replaced with a suitable reset IC© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 23
6.4 Brown-out Detect
An internal brown-out detect module is used to monitor the supply voltage to the JN5148; this can be used whilst the
device is awake or is in CPU doze mode. Dips in the supply voltage below a variable threshold can be detected and
can be used to cause the JN5148 to perform a chip reset. Equally, dips in the supply voltage can be detected and
used to cause an interrupt to the processor, when the voltage either drops below the threshold or rises above it.
The brown-out detect is enabled by default from power-up and can extend the reset during power-up. This will keep
the CPU in reset until the voltage exceeds the brown-out threshold voltage. The threshold voltage is configurable to
2.0V, 2.3V, 2.7V and 3.0V and is controllable by software. From power-up the threshold is set by eFuse settings and
the default chip configuration is for the 2.3V threshold. It is recommended that the threshold is set so that, as a
minimum, the chip is held in reset until the voltage reaches the level required by the external memory device on the
SPI interface.
6.5 Watchdog Timer
A watchdog timer is provided to guard against software lockups. It operates by counting cycles of the 32kHz system
clock. A pre-scaler is provided to allow the expiry period to be set between typically 8ms and 16.4 seconds. Failure
to restart the watchdog timer within the pre-configured timer period will cause a chip reset to be performed. A status
bit is set if the watchdog was triggered so that the software can differentiate watchdog initiated resets from other
resets, and can perform any required recovery once it restarts. If the source of the 32kHz system clock is the 32kHz
RC oscillator then the watchdog expiry periods are subject to the variation in period of the RC oscillator.
After power up, reset, start from deep sleep or start from sleep, the watchdog is always enabled with the largest
timeout period and will commence counting as if it had just been restarted. Under software control the watchdog can
be disabled. If it is enabled, the user must regularly restart the watchdog timer to stop it from expiring and causing a
reset. The watchdog runs continuously, even during doze, however the watchdog does not operate during sleep or
deep sleep, or when the hardware debugger has taken control of the CPU. It will recommence automatically if
enabled once the debugger un-stalls the CPU. 24 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
7 Interrupt System
The interrupt system on the JN5148 is a hardware-vectored interrupt system. The JN5148 provides several interrupt
sources, some associated with CPU operations (CPU exceptions) and others which are used by hardware in the
device. When an interrupt occurs, the CPU stops executing the current program and loads its program counter with a
fixed hardware address specific to that interrupt. The interrupt handler or interrupt service routine is stored at this
location and is run on the next CPU cycle. Execution of interrupt service routines is always performed in supervisor
mode. Interrupt sources and their vector locations are listed in Table 2 below:
Interrupt Source Vector Location Interrupt Definition
Bus error 0x08 Typically cause by an attempt to access an invalid address or a
disabled peripheral
Tick timer 0x0e Tick timer interrupt asserted
Alignment error 0x14 Load/store address to non-naturally-aligned location
Illegal instruction 0x1a Attempt to execute an unrecognised instruction
Hardware interrupt 0x20 interrupt asserted
System call 0x26 System call initiated by b.sys instruction
Trap 0x2c caused by the b.trap instruction or the debug unit
Reset 0x38 Caused by software or hardware reset.
Stack Overflow 0x3e Stack overflow
Table 2: Interrupt Vectors
7.1 System Calls
The b.trap and b.sys instructions allow processor exceptions to be generated by software.
A system call exception will be generated when the b.sys instruction is executed. This exception can, for example, be
used to enable a task to switch the processor into supervisor mode when a real time operating system is in use. (See
section 3 for further details.)
The b.trap instruction is commonly used for trapping errors and for debugging.
7.2 Processor Exceptions
7.2.1 Bus Error
A bus error exception is generated when software attempts to access a memory address that does not exist, or is not
populated with memory or peripheral registers or when writing to ROM.
7.2.2 Alignment
Alignment exceptions are generated when software attempts to access objects that are not aligned to natural word
boundaries. 16-bit objects must be stored on even byte boundaries, while 32-bit objects must be stored on quad byte
boundaries. For instance, attempting to read a 16-bit object from address 0xFFF1 will trigger an alignment exception
as will a read of a 32-bit object from 0xFFF1, 0xFFF2 or 0xFFF3. Examples of legal 32-bit object addresses are
0xFFF0, 0xFFF4, 0xFFF8 etc.
7.2.3 Illegal Instruction
If the CPU reads an unrecognised instruction from memory as part of its instruction fetch, it will cause an illegal
instruction exception.
7.2.4 Stack Overflow
When enabled, a stack overflow exception occurs if the stack pointer reaches a programmable location.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 25
7.3 Hardware Interrupts
Hardware interrupts generated from the transceiver, analogue or digital peripherals and DIO pins are individually
masked using the Programmable Interrupt Controller (PIC). Management of interrupts is provided in the peripherals
library [5]. For details of the interrupts generated from each peripheral see the respective section in this datasheet.
Interrupts can be used to wake the JN5148 from sleep. The peripherals, baseband controller, security coprocessor
and PIC are powered down during sleep but the DIO interrupts and optionally the pulse counters, wake-up timers and
analogue comparator interrupts remain powered to bring the JN5148 out of sleep.
Prioritised external interrupt handling (i.e., interrupts from hardware peripherals) is provided to enable an application
to control an events priority to provide for deterministic program execution.
The priority Interrupt controller provides 15 levels of prioritised interrupts. The priority level of all interrupts can be set,
with value 0 being used to indicate that the source can never produce an external interrupt, 1 for the lowest priority
source(s) and 15 for the highest priority source(s). Note that multiple interrupt sources can be assigned the same
priority level if desired.
If while processing an interrupt, a new event occurs at the same or lower priority level, a new external interrupt will
not be triggered. However, if a new higher priority event occurs, the external interrupt will again be asserted,
interrupting the current interrupt service routine.
Once the interrupt service routine is complete, lower priority events can be serviced. 26 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
8 Wireless Transceiver
The wireless transceiver comprises a 2.45GHz radio, modem, a baseband processor, a security coprocessor and
PHY controller. These blocks, with protocol software provided as a library, implement an IEEE802.15.4 standardsbased
wireless transceiver that transmits and receives data over the air in the unlicensed 2.4GHz band.

Figure 14: Radio Architecture
The radio comprises a low-IF receive path and a direct modulation transmit path, which converge at the TX/RX
switch. The switch connects to the external single ended matching network, which consists of two inductors and a
capacitor, this arrangement creates a 50Ω port and removes the need for a balun. A 50Ω single ended antenna can
be connected directly to this port.
The 32MHz crystal oscillator feeds a divider, which provides the frequency synthesiser with a reference frequency.
The synthesiser contains programmable feedback dividers, phase detector, charge pump and internal Voltage
Controlled Oscillator (VCO). The VCO has no external components, and includes calibration circuitry to compensate
for differences in internal component values due to process and temperature variations. The VCO is controlled by a
Phase Locked Loop (PLL) that has an internal loop filter. A programmable charge pump is also used to tune the loop
characteristic.
The receiver chain starts with the low noise amplifier / mixer combination whose outputs are passed to a lowpass
filter, which provides the channel definition. The signal is then passed to a series of amplifier blocks forming a limiting
strip. The signal is converted to a digital signal before being passed to the Modem. The gain control for the RX path
is derived in the automatic gain control (AGC) block within the Modem, which samples the signal level at various
points down the RX chain. To improve the performance and reduce current consumption, automatic calibration is
applied to various blocks in the RX path.
In the transmit direction, the digital stream from the Modem is passed to a digital sigma-delta modulator which
controls the feedback dividers in the synthesiser, (dual point modulation). The VCO frequency now tracks the applied
modulation. The 2.4 GHz signal from the VCO is then passed to the RF Power Amplifier (PA), whose power control
can be selected from one of three settings. The output of the PA drives the antenna via the RX/TX switch© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 27
8.1.1 Radio External Components
In order to realise the full performance of the radio it is essential that the reference PCB layout and BOM are carefully
followed. See Appendix B.4.
The radio is powered from a number of internal 1.8V regulators fed from the analogue supply VDD1, in order to
provide good noise isolation between the digital logic of the JN5148 and the analogue blocks. These regulators are
also controlled by the baseband controller and protocol software to minimise power consumption. Decoupling for
internal regulators is required as described in section 2.2.1, Power Supplies
For single ended antennas or connectors, a balun is not required, however a matching network is needed.
The RF matching network requires three external components and the IBIAS pin requires one external component as
shown in schematic in B.4.1. These components are critical and should be placed close to the JN5148 pins and
analogue ground as defined in Table 8: JN5148 Printed Antenna Reference Module Components and PCB Layout
Constraints. Specifically, the output of the network comprising L2, C1 and L1 is designed to present an accurate
match to a 50 ohm resistive network as well as provide a DC path to the final output stage or antenna. Users wishing
to match to other active devices such as amplifiers should design their networks to match to 50 ohms at the output of

Support is provided for antenna diversity. Antenna diversity is a technique that maximises the performance of an
antenna system. It allows the radio to switch between two antennas that have very low correlation between their
received signals. Typically, this is achieved by spacing two antennas around 0.25 wavelengths apart or by using two
orthogonal polarisations. So, if a packet is transmitted and no acknowledgement is received, the radio system can
switch to the other antenna for the retry, with a different probability of success.
The JN5148 provides an output (ADO) on DIO12 that is asserted on odd numbered retries and optionally its
complement (ADE) on DIO13, that can be used to control an antenna switch; this enables antenna diversity to be
implemented easily (see Figure 16 and Figure 17).28 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

8.2 Modem
The modem performs all the necessary modulation and spreading functions required for digital transmission and
reception of data at 250kbps in the 2450MHz radio frequency band in compliance with the IEEE802.15.4 standard. It
also provides a high data rate modes at 500 and 667kbps.

Features provided to support network channel selection algorithms include Energy Detection (ED), Link Quality
Indication (LQI) and fully programmable Clear Channel Assessment (CCA).
The Modem provides a digital Receive Signal Strength Indication (RSSI) that facilitates the implementation of the
IEEE 802.15.4 ED function and LQI function.
The ED and LQI are both related to receiver power in the same way, as shown in Fig19. LQI is associated with a
received packet, whereas ED is an indication of signal power on air at a particular moment.
The CCA capability of the Modem supports all modes of operation defined in the IEEE 802.15.4 standard, namely
Energy above ED threshold, Carrier Sense and Carrier Sense and/or energy above ED threshold.

8.3 Baseband Processor
The baseband processor provides all time-critical functions of the IEEE802.15.4 MAC layer. Dedicated hardware
guarantees air interface timing is precise. The MAC layer hardware/software partitioning, enables software to
implement the sequencing of events required by the protocol and to schedule timed events with millisecond
resolution, and the hardware to implement specific events with microsecond timing resolution. The protocol software
layer performs the higher-layer aspects of the protocol, sending management and data messages between endpoint
and coordinator nodes, using the services provided by the baseband processor.

8.3.1 Transmit
A transmission is performed by software writing the data to be transferred into the Tx/Rx Frame Buffer, together with
parameters such as the destination address and the number of retries allowed, and programming one of the protocol
timers to indicate the time at which the frame is to be sent. This time will be determined by the software tracking the
higher-layer aspects of the protocol such as superframe timing and slot boundaries. Once the packet is prepared and
protocol timer set, the supervisor block controls the transmission. When the scheduled time arrives, the supervisor
controls the sequencing of the radio and modem to perform the type of transmission required. It can perform all the
algorithms required by IEEE802.15.4 such as CSMA/CA, GTS without processor intervention including retries and
random backoffs.
When the transmission begins, the header of the frame is constructed from the parameters programmed by the
software and sent with the frame data through the serialiser to the Modem. At the same time, the radio is prepared
for transmission. During the passage of the bitstream to the modem, it passes through a CRC checksum generator
that calculates the checksum on-the-fly, and appends it to the end of the frame.
If using slotted access, it is possible for a transmission to overrun the time in its allocated slot; the Baseband
Processor handles this situation autonomously and notifies the protocol software via interrupt, rather than requiring it
to handle the overrun explicitly.
8.3.2 Reception
During reception, the radio is set to receive on a particular channel. On receipt of data from the modem, the frame is
directed into the Tx/Rx Frame Buffer where both header and frame data can be read by the protocol software. An
interrupt may be provided on receipt of the frame header. As the frame data is being received from the modem it is
passed through a checksum generator; at the end of the reception the checksum result is compared with the
checksum at the end of the message to ensure that the data has been received correctly. An interrupt may be © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 31
provided to indicate successful packet reception. During reception, the modem determines the Link Quality, which is
made available at the end of the reception as part of the requirements of IEEE802.15.4.
8.3.3 Auto Acknowledge
Part of the protocol allows for transmitted frames to be acknowledged by the destination sending an acknowledge
packet within a very short window after the transmitted frame has been received. The JN5148 baseband processor
can automatically construct and send the acknowledgement packet without processor intervention and hence avoid
the protocol software being involved in time-critical processing within the acknowledge sequence. The JN5148
baseband processor can also request an acknowledge for packets being transmitted and handle the reception of
acknowledged packets without processor intervention.
8.3.4 Beacon Generation
In beaconing networks, the baseband processor can automatically generate and send beacon frames; the repetition
rate of the beacons is programmed by the CPU, and the baseband then constructs the beacon contents from data
delivered by the CPU. The baseband processor schedules the beacons and transmits them without CPU
intervention.
8.3.5 Security
The transmission and reception of secured frames using the Advanced Encryption Standard (AES) algorithm is
handled by the security coprocessor and the stack software. The application software must provide the appropriate
encrypt/decrypt keys for the transmission or reception. On transmission, the key can be programmed at the same
time as the rest of the frame data and setup information.
8.4 Security Coprocessor
The security coprocessor is available to the application software to perform encryption/decryption operations. A
hardware implementation of the encryption engine significantly speeds up the processing of the encrypted packets
over a pure software implementation. The AES library for the JN5148 provides operations that utilise the encryption
engine in the device and allow the contents of memory buffers to be transformed. Information such as the type of
security operation to be performed and the encrypt/decrypt key to be used must also be provided.

8.5 Location Awareness
The JN5148 provides the ability for an application to obtain the Time Of Flight (TOF) between two network nodes.
The TOF information is an alternative metric to that of the existing Energy Detect value (RSSI) that has been typically
used for calculating the relative inter-nodal separation, for subsequent use in a location awareness system.
For short ranges RSSI will typically give a better accuracy than TOF, however for distances above 5 to 10 meters
TOF will offer significant improvements in accuracy compared to RSSI. In general, the RSSI error scales with
distance, such that if the distance doubles then the error doubles.32 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
8.6 Higher Data Rates
To support the demands of applications that require high data throughputs such as in audio or data streaming
applications, the JN5148 supports higher data rate modes that offer 500kbps or 667kbps on air transmission rates.
The switching between standard and higher data rates is controlled via software, When operating in a higher data
rate mode standard IEEE802.15.4 features, such as clear channel assessment, can still be used. This allows the
JN5148 in a higher data rate mode to co-exist in an IEEE802.15.4 based network (adhering to the correct bit rates
and frame timing etc.) whilst at the same time providing the benefit of the higher data rate where required.
When operating in a higher data rate mode, the receive sensitivity will be degraded by at least 3dB.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 33
9 Digital Input/Output
There are 21 Digital I/O (DIO) pins, which can be configured as either an input or an output, and each has a
selectable internal pull-up resistor. Most DIO pins are multiplexed with alternate peripheral features of the device,
see section 2.1. Once a peripheral is enabled it takes precedence over the device pins. Refer to the individual
module sections for a full description of the alternate peripherals functions. Following a reset (and whilst the reset
input is held low), all peripherals are off and the DIO pins are configured as inputs with the internals pull-ups turned
on.
When a peripheral is not enabled, the DIO pins associated with it can be used as digital inputs or outputs. Each pin
can be controlled individually by setting the direction and then reading or writing to the pin.
The individual pull-up resistors, RPU, can also be enabled or disabled as needed and the setting is held through sleep
cycles. The pull-ups are generally configured once after reset depending on the external components and
functionality. For instance, outputs should generally have the pull-ups disabled. An input that is always driven should
also have the pull-up disabled.
When configured as an input each pin can be used to generate an interrupt upon a change of state (selectable
transition either from low to high or high to low); the interrupt can be enabled or disabled. When the device is
sleeping, these interrupts become events that can be used to wake the device up. Equally the status of the interrupt
may be read. See section 21 Power Management and Sleep Modes for further details on sleep and wakeup.
The state of all DIO pins can be read, irrespective of whether the DIO is configured as an input or an output.
Throughout a sleep cycle the direction of the DIO, and the state of the outputs, is held. This is based on the resultant
of the GPIO Data/ Direction registers and the effect of any enabled peripherals at the point of entering sleep.
Following a wake-up these directions and output values are maintained under control of the GPIO data / direction
registers. Any peripherals enabled before the sleep cycle are not automatically re-enabled, this must be done through
software after the wake-up.
For example, if DIO0 is configured to be SPISEL1 then it becomes an output. The output value is controlled by the
SPI functional block. If the device then enters a sleep cycle, the DIO will remain an output and hold the value being
output when entering sleep. After wake-up the DIO will still be an output with the same value but controlled from the
GPIO Data/Direction registers. It can be altered with the software functions that adjust the DIO, or the application may
re-configure it to be SPISEL1.
Unused DIO pins are recommended to be set as inputs with the pull-up enabled.
Two DIO pins can optionally be used to provide control signals for RF circuitry (eg switches and PA) in high power
range extenders.
DIO3 / RFTX is asserted when the radio is in the transmit state and similarly, DIO2 / RFRX is asserted when the radio
is in the receiver state.34 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

10 Serial Peripheral Interface
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the JN5148 and
peripheral devices. The JN5148 operates as a master on the SPI bus and all other devices connected to the SPI are
expected to be slave devices under the control of the JN5148 CPU. The SPI includes the following features:
• Full-duplex, three-wire synchronous data transfer
• Programmable bit rates (up to 16Mbit/s)
• Programmable transaction size up to 32-bits
• Standard SPI modes 0,1,2 and 3
• Manual or Automatic slave select generation (up to 5 slaves)
• Maskable transaction complete interrupt
• LSB First or MSB First Data Transfer
• Supports delayed read edges

Figure 23: SPI Block Diagram
The SPI bus employs a simple shift register data transfer scheme. Data is clocked out of and into the active devices
in a first-in, first-out fashion allowing SPI devices to transmit and receive data simultaneously.
There are three dedicated pins SPICLK, SPIMOSI, SPIMISO that are shared across all devices on the bus. MasterOut-Slave-In
or Master-In-Slave-Out data transfer is relative to the clock signal SPICLK generated by the JN5148.
The JN5148 provides five slave selects, SPISEL0 to SPISEL4 to allow five SPI peripherals on the bus. SPISEL0 is a
dedicated pin; this is generally connected to a serial Flash/ EEPROM memory holding application code that is
downloaded to internal RAM via software from reset. SPISEL1 to 4, are alternate functions of pins DIO0 to 3
respectively.
The interface can transfer from 1 to 32-bits without software intervention and can keep the slave select lines asserted
between transfers when required, to enable longer transfers to be performed.
When the device reset is active, the three outputs SPISEL, SPICLK and SPI_MOSI are tri-stated and SPI_MISO is
set to be an input. The pull-up resistors associated with all four pins will be active at this time. 36 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 SI

Figure 24: Typical JN5148 SPI Peripheral Connection
The data transfer rate on the SPI bus is determined by the SPICLK signal. The JN5148 supports transfers at
selectable data rates from 16MHz to 125kHz selected by a clock divider. Both SPICLK clock phase and polarity are
configurable. The clock phase determines which edge of SPICLK is used by the JN5148 to present new data on the
SPIMOSI line; the opposite edge will be used to read data from the SPIMISO line. The interface should be configured
appropriately for the SPI slave being accessed.

Table 3 SPI Configurations
If more than one SPISEL line is to be used in a system they must be used in numerical order starting from SPISEL0.
For instance if 3 SPI select lines are to be used, they must be SPISEL0, 1 and 2. A SPISEL line can be automatically
deasserted between transactions if required, or it may stay asserted over a number of transactions. For devices such
as memories where a large amount of data can be received by the master by continually providing SPICLK
transitions, the ability for the select line to stay asserted is an advantage since it keeps the slave enabled over the
whole of the transfer.
A transaction commences with the SPI bus being set to the correct configuration, and then the slave device is
selected. Upon commencement of transmission (1 to 32 bits) data is placed in the FIFO data buffer and clocked out,
at the same time generating the corresponding SPICLK transitions. Since the transfer is full-duplex, the same
number of data bits is being received from the slave as it transmits. The data that is received during this transmission
can be read (1 to 32 bits). If the master simply needs to provide a number of SPICLK transitions to allow data to be © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 37
sent from a slave, it should perform transmit using dummy data. An interrupt can be generated when the transaction
has completed or alternatively the interface can be polled.
If a slave device wishes to signal the JN5148 indicating that it has data to provide, it may be connected to one of the
DIO pins that can be enabled as an interrupt.
Figure 25 shows a complex SPI transfer, reading data from a FLASH device, that can be achieved using the SPI
master interface. The slave select line must stay low for many separate SPI accesses, and therefore manual slave
select mode must be used. The required slave select can then be asserted (active low) at the start of the transfer. A
sequence 8 and 32 bit transfers can be used to issue the command and address to the FLASH device and then to
read data back. Finally, the slave select can be deselected to end the transaction.

11 Timers
11.1 Peripheral Timer/Counters
Three general-purpose timer/counter units are available that can be independently configured to operate in one of
five possible modes. Timer 0 and 1 support all 5 modes of operation and Timer 2 supports PWM and Delta-Sigma
modes only. The timers have the following:
• 5-bit prescaler, divides system clock by 2 prescale value as the clock to the timer (prescaler range is 0 to 16)
• Clocked from internal system clock (16MHz)
• 16-bit counter, 16-bit Rise and Fall (period) registers
• Timer: can generate interrupts off Rise and Fall counts. Can be gated by external signal
• Counter: counts number of transitions on external event signal. Can use low-high, high-low or both
transitions
• PWM/Single pulse: outputs repeating Pulse Width Modulation signal or a single pulse. Can set period and
mark-space ratio
• Capture: measures times between transitions of an applied signal
• Delta-Sigma: Return-To-Zero (RTZ) and Non-Return-to-Zero (NRZ) modes
• Timer usage of external IO can be controlled on a pin by pin basis

The clock source for the timer unit is fed from the 16MHz system clock. This clock passes to a 5-bit prescaler where a
value of 0 leaves the clock unmodified and other values divide it by 2 prescale value. For example, a prescale value of
2 applied to the 16MHz system clock source results in a timer clock of 4MHz.
The counter is optionally gated by a signal on the clock/gate input (TIMxCK_GT). If the gate function is selected,
then the counter is frozen when the clock/gate input is high.
An interrupt can be generated whenever the counter is equal to the value in either of the High or Low registers.
The internal Output Enable (OE) signal enables or disables the timer output.
The Timer 0 signals CK_GT, CAP and OUT are alternate functions of pins DIO8, 9 and 10 respectively and Timer 1
signals CK_GT, CAP and OUT are alternate functions of pins DIO11, 12, and 13 respectively. Timer 2 OUT is an
alternate function of DIO11 If operating in timer mode it is not necessary to use any of the DIO pins, allowing the
standard DIO functionality to be available to the application.
Note, timer 0 may only be used as an internal timer or in counter mode (counting events) if an external 32kHz crystal
is used. If timer 2 is used in PWM or Delta-Sigma mode then timer 1 does not have access to its clock/gate pin.
Therefore, it can not operate in counter mode (counting events) or use the gate function.
11.1.1 Pulse Width Modulation Mode
Pulse Width Modulation (PWM) mode allows the user to specify an overall cycle time and pulse length within the
cycle. The pulse can be generated either as a single shot or as a train of pulses with a repetition rate determined by
the cycle time.
In this mode, the cycle time and low periods of the PWM output signal can be set by the values of two independent
16-bit registers (Fall and Rise). The counter increments and its output is compared to the 16-bit Rise and Fall
registers. When the counter is equal to the Rise register, the PWM output is set to high; when the counter reaches
the Fall value, the output returns to low. In continuous mode, when the counter reaches the Fall value, it will reset
and the cycle repeats. The PWM waveform is available on TIMxOUT when the output driver is enabled.
Rise
Fall
Figure 27: PWM Output Timings
11.1.2 Capture Mode
The capture mode can be used to measure the time between transitions of a signal applied to the capture input
(TIMxCAP). When the capture is started, on the next low-to-high transition of the captured signal, the count value is
stored in the Rise register, and on the following high-to-low transition, the counter value is stored in the Fall register.
The pulse width is the difference in counts in the two registers multiplied by the period of the prescaled clock. Upon
reading the capture registers the counter is stopped. The values in the High and Low registers will be updated
whenever there is a corresponding transition on the capture input, and the value stored will be relative to when the
mode was started. Therefore, if multiple pulses are seen on TIMxCAP before the counter is stopped only the last
pulse width will be stored.40 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

11.1.3 Counter/Timer Mode
The counter/timer can be used to generate interrupts, based on the timers or event counting, for software to use. As
a timer the clock source is from the system clock, prescaled if required. The timer period is programmed into the Fall
register and the Fall register match interrupt enabled. The timer is started as either a single-shot or a repeating timer,
and generates an interrupt when the counter reaches the Fall register value.
When used to count external events on TIMxCK_GT the clock source is selected from the input pin and the number
of events programmed into the Fall register. The Fall register match interrupt is enabled and the counter started,
usually in single shot mode. An interrupt is generated when the programmed number of transitions is seen on the
input pin. The transitions counted can configured to be rising, falling or both rising and falling edges.
Edges on the event signal must be at least 100nsec apart, i.e. pulses must be wider than 100nsec.
11.1.4 Delta-Sigma Mode
A separate delta-sigma mode is available, allowing a low speed delta-sigma DAC to be implemented with up to 16-bit
resolution. This requires that a resistor-capacitor network is placed between the output DIO pin and digital ground. A
stream of pulses with digital voltage levels is generated which is integrated by the RC network to give an analogue
voltage. A conversion time is defined in terms of a number of clock cycles. The width of the pulses generated is the
period of a clock cycle. The number of pulses output in the cycle, together with the integrator RC values, will
determine the resulting analogue voltage. For example, generating approximately half the number of pulses that
make up a complete conversion period will produce a voltage on the RC output of VDD1/2, provided the RC time
constant is chosen correctly. During a conversion, the pulses will be pseudo-randomly dispersed throughout the
cycle in order to produce a steady voltage on the output of the RC network.
The output signal is asserted for the number of clock periods defined in the High register, with the total period being
216 cycles. For the same value in the High register, the pattern of pulses on subsequent cycles is different, due to the
pseudo-random distribution.
The delta-sigma convertor output can operate in a Return-To-Zero (RTZ) or a Non-Return-to-Zero (NRZ) mode. The
NRZ mode will allow several pulses to be output next to each other. The RTZ mode ensures that each pulse is
separated from the next by at least one period. This improves linearity if the rise and fall times of the output are
different to one another. Essentially, the output signal is low on every other output clock period, and the conversion
cycle time is twice the NRZ cycle time ie 217 clocks. The integrated output will only reach half VDD2 in RTZ mode,
since even at full scale only half the cycle contains pulses. Figure 29 and Figure 30 illustrate the difference between
RTZ and NRZ for the same programmed number of pulses.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 41

11.1.5 Example Timer / Counter Application
Figure 31 shows an application of the JN5148 timers to provide closed loop speed control. Timer 0 is configured in
PWM mode to provide a variable mark-space ratio switching waveform to the gate of the NFET. This in turn controls
the power in the DC motor.
Timer 1 is configured to count the rising edge events on the clk/gate pin over a constant period. This converts the
tacho pulse stream output into a count proportional to the motor speed. This value is then used by the application
software executing the control algorithm.
If required for other functionality, then the unused IO associated with the timers could be used as general purpose
DIO.

11.2 Tick Timer
The JN5148 contains a hardware timer that can be used for generating timing interrupts to software. It may be used
to implement regular events such as ticks for software timers or an operating system, as a high-precision timing
reference or can be used to implement system monitor timeouts as used in a watchdog timer. Features include:
• 32-bit counter42 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
• 28-bit match value
• Maskable timer interrupt
• Single-shot, Restartable or Continuous modes of operation

Figure 32: Tick Timer
The Tick Timer is clocked from a continuous 16MHz clock, which is fed to a 32-bit wide resettable up-counter, gated
by a signal from the mode control block. A match register allows comparison between the counter and a
programmed value. The match value, measured in 16MHz clock cycles is programmed through software, in the
range 0 to 0x0FFFFFFF. The output of the comparison can be used to generate an interrupt if the interrupt is
enabled and used in controlling the counter in the different modes. Upon configuring the timer mode, the counter is
also reset.
If the mode is programmed as single shot, the counter begins to count from zero until the match value is reached.
The match signal will be generated which will cause an interrupt if enabled, and the counter will stop counting. The
counter is restarted by reprogramming the mode.
If the mode is programmed as restartable, the operation of the counter is the same as for the single shot mode,
except that when the match value is reached the counter is reset and begins counting from zero. An interrupt will be
generated when the match value is reached if it is enabled.
Continuous mode operation is similar to restartable, except that when the match value is reached, the counter is not
reset but continues to count. An interrupt will be generated when the match value is reached if enabled.
11.3 Wakeup Timers
Two 32-bit wakeup timers are available in the JN5148 driven from the 32kHz internal clock. They may run during
sleep periods when the majority of the rest of the device is powered down, to time sleep periods or other long period
timings that may be required by the application. The wakeup timers do not run during deep sleep and may optionally
be disabled in sleep mode through software control. When a wakeup timer expires it typically generates an interrupt,
if the device is asleep then the interrupt may be used as an event to end the sleep period. See Section 21 for further
details on how they are used during sleep periods. Features include:
• 35-bit down-counter
• Optionally runs during sleep periods
• Clocked by 32kHz system clock; either 32kHz RC oscillator, 32kHz XTAL oscillator or 32kHz clock input© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 43
A wakeup timer consists of a 35-bit down counter clocked from the selected 32 kHz clock. An interrupt or wakeup
event can be generated when the counter reaches zero. On reaching zero the counter will continue to count down
until stopped, which allows the latency in responding to the interrupt to be measured. If an interrupt or wakeup event
is required, the timer interrupt should be enabled before loading the count value for the period. Once the count value
is loaded and counter started, the counter begins to count down; the counter can be stopped at any time through
software control. The counter will remain at the value it contained when the timer was stopped and no interrupt will
be generated. The status of the timers can be read to indicate if the timers are running and/or have expired; this is
useful when the timer interrupts are masked. This operation will reset any expired status flags.
11.3.1 RC Oscillator Calibration
The RC oscillator that can be used to time sleep periods is designed to require very little power to operate and be
self-contained, requiring no external timing components and hence is lower cost. As a consequence of using on-chip
resistors and capacitors, the inherent absolute accuracy and temperature coefficient is lower than that of a crystal
oscillator, but once calibrated the accuracy approaches that of a crystal oscillator. Sleep time periods should be as
close to the desired time as possible in order to allow the device to wake up in time for important events, for example
beacon transmissions in the IEEE802.15.4 protocol. If the sleep time is accurate, the device can be programmed to
wake up very close to the calculated time of the event and so keep current consumption to a minimum. If the sleep
time is less accurate, it will be necessary to wake up earlier in order to be certain the event will be captured. If the
device wakes earlier, it will be awake for longer and so reduce battery life.
In order to allow sleep time periods to be as close to the desired length as possible, the true frequency of the RC
oscillator needs to be determined to better than the initial 30% accuracy. The calibration factor can then be used to
calculate the true number of nominal 32kHz periods needed to make up a particular sleep time. A calibration
reference counter, clocked from the 16MHz system clock, is provided to allow comparisons to be made between the
32kHz RC clock and the 16MHz system clock when the JN5148 is awake.
Wakeup timer0 counts for a set number of 32kHz clock periods during which time the reference counter runs. When
the wakeup timer reaches zero the reference counter is stopped, allowing software to read the number of 16MHz
clock ticks generated during the time represented by the number of 32kHz ticks programmed in the wakeup timer.
The true period of the 32kHz clock can thus be determined and used when programming a wakeup timer to achieve a
better accuracy and hence more accurate sleep periods
For a RC oscillator running at exactly 32,000Hz the value returned by the calibration procedure should be 10000, for
a calibration period of twenty 32,000Hz clock periods. If the oscillator is running faster than 32,000Hz the count will
be less than 10000, if running slower the value will be higher. For a calibration count of 9000, indicating that the RC
oscillator period is running at approximately 35kHz, to time for a period of 2 seconds the timer should be loaded with
71,111 ((10000/9000) x (32000 x 2)) rather than 64000.44 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
12 Pulse Counters
Two 16-bit counters are provided that can increment during all modes of operation (including sleep), based on pulses
received on 2 dedicated DIO inputs; DIO1 and DIO8. The pulses can be de-bounced using the 32kHz clock to guard
against false counting on slow or noisy edges. Increments occur from a configurable rising or falling edge on the
respective DIO input.
Each counter has an associated 16-bit reference that is loaded by the user. An interrupt (and wakeup event if
asleep) may be generated when a counter reaches its pre-configured reference value. The two counters may
optionally be cascaded together to provide a single 32-bit counter, linked to DIO1. The counters do not saturate at
65535, but naturally roll-over to 0. Additionally, the pulse counting continues when the reference value is reached
without software interaction so that pulses are not missed even if there is a long delay before an interrupt is serviced
or during the wakeup process.
The system can work with signals up to 100kHz, with no debounce, or from 5.3kHz to 1.7kHz with debounce. When
using debounce the 32kHz clock must be active, so for minimum sleep currents the debounce mode should not be
used.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 45
13 Serial Communications
The JN5148 has two independent Universal Asynchronous Receiver/Transmitter (UART) serial communication
interfaces. These provide similar operating features to the industry standard 16550A device operating in FIFO mode.
Each interface performs serial-to-parallel conversion on incoming serial data and parallel-to-serial conversion on
outgoing data from the CPU to external devices. In both directions, a 16-byte deep FIFO buffer allows the CPU to
read and write multiple characters on each transaction. This means that the CPU is freed from handling data on a
character-by-character basis, with the associated high processor overhead. The UARTs have the following features:
• Emulates behaviour of industry standard NS16450 and NS16550A UARTs
• 16 byte transmit and receive FIFO buffers reduce interrupts to CPU, with direct access to fill levels of each
• Adds / deletes standard start, stop and parity communication bits to or from the serial data
• Independently controlled transmit, receive, status and data sent interrupts
• Optional modem flow control signals CTS and RTS
• Fully programmable data formats: baud rate, start, stop and parity settings
• False start bit detection, parity, framing and FIFO overrun error detect and break indication
• Internal diagnostic capabilities: loop-back controls for communications link fault isolation
• Flow control by software or automatically by hardware Processor Bus

Figure 33: UART Block Diagram
The serial interface contains programmable fields that can be used to set number of data bits (5, 6,7 or 8), even, odd,
set-at-1, set-at-0 or no-parity detection and generation of single or multiple stop bit, (for 5 bit data, multiple is 1.5 stop
bits; for 6, 7 or 8 data bits, multiple is 2 bits).
The baud rate is programmable up to 1Mbps, standard baud rates such as 4800, 9600, 19.2k, 38.4k etc. can be
configured.
For applications requiring hardware flow control, two control signals are provided: Clear-To-Send (CTS) and RequestTo-Send
(RTS). CTS is an indication sent by an external device to the UART that it is ready to receive data. RTS is
an indication sent by the UART to the external device that it is ready to receive data. RTS is controlled from software,
while the value of CTS can be read. Monitoring and control of CTS and RTS is a software activity, normally
performed as part of interrupt processing. The signals do not control parts of the UART hardware, but simply indicate
to software the state of the UART external interface. Alternatively, the Automatic Flow Control mode can be set 46 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
where the hardware controls the value of the generated RTS (negated if the receive FIFO fill level is greater than a
programmable threshold of 8, 11, 13 or 15 bytes), and only transmits data when the incoming CTS is asserted.
Software can read characters, one byte at a time, from the Receive FIFO and can also write to the Transmit FIFO,
one byte at a time. The Transmit and Receive FIFOs can be cleared and reset independently of each other. The
status of the transmitter can be checked to see if it is empty, and if there is a character being transmitted. The status
of the receiver can also be checked, indicating if conditions such as parity error, framing error or break indication
have occurred. It also shows if an overrun error occurred (receive buffer full and another character arrives) and if
there is data held in the receive FIFO.
UART 0 signals CTS, RTS, TXD and RXD are alternate functions of pins DIO4, 5, 6 and 7 respectively and UART 1
signals CTS, RTS, TXD and RXD are alternate functions of pins DIO17, 18, 19 and 20 respectively. If CTS and RTS
are not required on the devices external pins, then they may be disabled, this allows the DIOx function to be used for
other purposes.
Note: With the automatic flow control threshold set to 15, the hardware flow control within the UART block negates
RTS when the receive FIFO is about to become full. In some instances it has been observed that remote devices that
are transmitting data do not respond quickly enough to the de-asserted CTS and continue to transmit data. In these
instances the data will be lost in a receive FIFO overflow.
13.1 Interrupts
Interrupt generation can be controlled for the UART block, and is divided into four categories:
• Received Data Available: Is set when data in the Rx FIFO queue reaches a particular level (the trigger level can
be configured as 1, 4, 8 or 14) or if no character has been received for 4 character times.
• Transmit FIFO Empty: set when the last character from the Tx FIFO is read and starts to be transmitted.
• Receiver Line Status: set when one of the following occur (1) Parity Error - the character at the head of the
receive FIFO has been received with a parity error, (2) Overrun Error - the Rx FIFO is full and another character
has been received at the Receiver shift register, (3) Framing Error - the character at the head of the receive
FIFO does not have a valid stop bit and (4) Break Interrupt – occurs when the RxD line has been held low for an
entire character.
• Modem Status: Generated when the CTS (Clear To Send) input control line changes.
13.2 UART Application

14 JTAG Debug Interface
The JN5148 includes an IEEE1149.1 compliant JTAG port for the sole purpose of software code debug with NXP's
Software Developer’s Kit. The JTAG interface is disabled by default and is enabled under software control.
Therefore, debugging is only possible if enabled by the application. Once enabled, the application executes as
normal until the external debugger controller initiates debug activity.
The Debugger supports breakpoints and watchpoints based on four comparisons between any of program counter,
load/store effective address and load/store data. There is the ability to chain the comparisons together. There is also
the ability, under debugger control to perform the following commands: go, stop, reset, step over/into/out/next, run to
cursor and breakpoints. In addition, under control of the debugger, it is possible to:
• Read and write registers on the wishbone bus
• Read ROM and RAM, and write to RAM
• Read and write CPU internal registers
The Debugger interface is accessed, depending upon the configuration, through the pins used for UART0 or UART1.
This is enabled under software control and is dealt with in JN-AN-1118 JN5148 Application Debugging [4]. The
following table details which DIO are used for the JTAG interface depending upon the configuration.

Table 4 Hardware Debugger IO
If doze mode is active when debugging is started, the processor will be woken and then respond to debugger
commands. It is not possible to wake the device from sleep using the debug interface and debugging is not available
while the device is sleeping.
When using the debug interface, program execution is halted, and control of the CPU is handed to the debugger. The
watchdog, tick timer and the three timers described in section 11 are stalled while the debugger is in control of the
CPU.
When control is handed from the CPU to the debugger or back a small number of CPU clock cycles are taken
flushing or reloading the CPU pipeline. Because of this, when a program is halted by the debugger and then restarted
again, a small number of tick timer cycles will elapse.
It is possible to prevent all hardware debugging by blowing the relevant Efuse bit.
The JTAG interface does not support boundary scan testing. It is recommended that the JN5148 is not connected as
part of the board scan chain.48 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
15 Two-Wire Serial Interface
The JN5148 includes industry standard two-wire synchronous Serial Interface operates as a Master (MSIF) or Slave
(SSIF) that provides a simple and efficient method of data exchange between devices. The system uses a serial data
line (SIF_D) and a serial clock line (SIF_CLK) to perform bi-directional data transfers and includes the following
features:
Common to both master and slave:
• Compatible with both I2
C and SMbus peripherals
• Support for 7 and 10-bit addressing modes
• Optional pulse suppression on signal inputs
Master only:
• Multi-master operation
• Software programmable clock frequency
• Clock stretching and wait state generation
• Software programmable acknowledge bit
• Interrupt or bit-polling driven byte-by-byte data-transfers
• Bus busy detection
Slave only:
• Programmable slave address
• Simple byte level transfer protocol
• Write data flow control with optional clock stretching or acknowledge mechanism
• Read data preloaded or provided as required
15.1 Connecting Devices
The clock and data lines, SIF_D and SIF_CLK, are alternate functions of DIO15 and DIO14 respectively. The serial
interface function of these pins is selected when the interface is enabled. They are both bi-directional lines,
connected internally to the positive supply voltage via weak (45kΩ) programmable pull-up resistors. However, it is
recommended that external 4.7kΩ pull-ups be used for reliable operation at high bus speeds, as shown in Figure 35.
When the bus is free, both lines are HIGH. The output stages of devices connected to the bus must have an opendrain
or open-collector in order to perform the wired-AND function. The number of devices connected to the bus is
solely dependent on the bus capacitance limit of 400pF.

15.2 Clock Stretching
Slave devices can use clock stretching to slow down the transfer bit rate. After the master has driven SIF_CLK low,
the slave can drive SIF_CLK low for the required period and then release it. If the slave’s SIF_CLK low period is
greater than the master’s low period the resulting SIF_CLK bus signal low period is stretched thus inserting wait
states.

15.3 Master Two-wire Serial Interface
When operating as a master device, it provides the clock signal and a prescale register determines the clock rate,
allowing operation up to 400kbit/s.
Data transfer is controlled from the processor bus interface at a byte level, with the processor responsible for
indicating when start, stop, read, write and acknowledge control should be generated. Write data written into a
transmit buffer will be written out across the two-wire interface when indicated, and read data received on the
interface is made available in a receive buffer. Indication of when a particular transfer has completed may be
indicated by means of an interrupt or by polling a status bit.
The first byte of data transferred by the device after a start bit is the slave address. The JN5148 supports both 7-bit
and 10-bit slave addresses by generating either one or two address transfers. Only the slave with a matching address
will respond by returning an acknowledge bit.
The master interface provides a true multi-master bus including collision detection and arbitration that prevents data
corruption. If two or more masters simultaneously try to control the bus, a clock synchronization procedure
determines the bus clock. Because of the wired-AND connection of the interface, a high-to-low transition on the bus
affects all connected devices. This means a high-to-low transition on the SIF_CLK line causes all concerned devices
to count off their low period. Once the clock input of a device has gone low, it will hold the SIF_CLK line in that state
until the clock high state is reached when it releases the SIF_CLK line. Due to the wired-AND connection, the
SIF_CLK line will therefore be held low by the device with the longest low period, and held high by the device with the
shortest high period.

After each transfer has completed, the status of the device must be checked to ensure that the data has been
acknowledged correctly, and that there has been no loss of arbitration. (N.B. Loss of arbitration may occur at any
point during the transfer, including data cycles). An interrupt will be generated when arbitration has been lost.50 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
15.4 Slave Two-wire Serial Interface
When operating as a slave device, the interface does not provide a clock signal, although it may drive the clock signal
low if it is required to apply clock stretching.
Only transfers whose address matches the value programmed into the interface’s address register are accepted. The
interface allows both 7 and 10 bit addresses to be programmed, but only responds with an acknowledge to a single
address. Addresses defined as “reserved” will not be responded to, and should not be programmed into the address
register. A list of reserved addresses is shown in Table 5.

0000 001 CBUS address Ignored

Table 5 : List of two-wire serial interface reserved addresses
Data transfer is controlled from the processor bus interface at a byte level, with the processor responsible for taking
write data from a receive buffer and providing read data to a transmit buffer when indicated. A series of interrupt
status bits are provided to control the flow of data.
For writes, in to the slave interface, it is important that data is taken from the receive buffer by the processor before
the next byte of data arrives. To enable this, the interface may be configured to work in two possible backoff modes:
• Not Acknowledge mode – where the interface returns a Not Acknowledge (NACK) to the master if more data
is received before the previous data has been taken. This will lead to the termination of the current data
transfer.
• Clock Stretching mode – where the interface holds the clock line low until the previous data has been taken.
This will occur after transfer of the next data but before issuing an acknowledge
For reads, from the slave interface, the data may be preloaded into the transmit buffer when it is empty (i.e. at the
start of day, or when the last data has been read), or fetched each time a read transfer is requested. When using data
preload, read data in the buffer must be replenished following a data write, as the transmit and received data is
contained in a shared buffer. The interface will hold the bus using clock stretching when the transmit buffer is empty.
Interrupts may be triggered when:
• Data Buffer read data is required – a byte of data to be read should be provided to avoid the interface from
clock stretching
• Data Buffer read data has been taken – this indicates when the next data may be preloaded into the data
buffer
• Data Buffer write data is available – a byte of data should be taken from the data buffer to avoid data backoff
as defined above
• The last data in a transfer has completed – i.e. the end of a burst of data, when a Stop or Restart is seen
• A protocol error has been spotted on the interface© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 51
16 Four-Wire Digital Audio Interface
The JN5148 includes a four-wire digital audio interface that can be used for interfacing to audio CODECs. The
following features are supported:
• Compatible with the industry standard I²S interface
• Option to support I²S, left justified and right justified modes
• Optional support for connection to mono sample FIFO with data transferred on the left or right channel
• Master only
• Transmit on falling edge and receive on rising edge
• Up to 8MHz maximum clock range
• Maximum system size of 32-bits, allowing up to 16-bits per channel (left or right channels)
• Option for pad bit insertion, allowing length of transfer per channel to be anything from 16 to 32 bits
• Data Transfer size range of 1 to 16-bits per channel
• Option to invert WS (normally 0 for left, but allow 1 for left instead)
• Continuous clock output option to support CODECs which use it as a clock source
• Separate input and output data lines
• Option to invert idle state of WS (to indicate left or right)
The Word Select (WS), Data In (SDIN), Clock (SCK) and Data Out (SDOUT) lines are alternate functions of DIO
lines 12,13,17 and 18 respectively.
Data transfer is always bidirectional. Data placed in the Data Buffer before a transfer command is issued will be
transmitted on SDOUT whilst the data received on SDIN will be placed in the Data Buffer at the end of the transfer.
Indication that a transfer has completed is by means of an interrupt or by polling a status bit.
Left channel data is always sent first, with MSB first on each channel. The interface will always transfer both left and
right channel data. For mono data transfer, the user should pad out the unused channel with 0’s, and ignore any data
returned on the unused channel.
The length of a data transfer is derived as follows:
• When padding is disabled – Data Transfer Length = 2 x Data Transfer Size
• When padding is enabled – Data Transfer Length = 2 x (16 + Extra Pad Length)
Timing of the 3 main modes is shown in Figure 38, Figure 39 and Figure 40. The Data Buffer shows how the data is
stored and how it will be transferred onto the interface. SD Max Size indicates how the maximum transfer size (16
with no additional padding) will transfer, whilst SD 3-bits indicates how 3 bits of data will be aligned when padding is
enabled. Received data in the Data Buffer will always be padded out with 0’s if the Data Transfer Size is less than 16-
bits, and any bits received beyond 16-bits when extra padding is used, will be discarded. In the examples, the polarity
of WS is shown with Left channel = 0, and the idle state is Right Channel. 52 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

17 Random Number Generator
A random number generator is provided which creates a 16-bit random number each time it is invoked. Consecutive
calls can be made to build up any length of random number required. Each call takes approximately 0.25msec to
complete. Alternatively, continuous generation mode can be used where a new number is generated approximately
every 0.25msec. In either mode of operation an interrupt can be generated to indicate when the number is available,
or a status bit can be polled.
The random bits are generated by sampling the state of the 32MHz clock every 32kHz system clock edge. As these
clocks are asynchronous to each other, each sampled bit is unpredictable and hence random.54 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
18 Sample FIFO
A 10 deep FIFO is provided to buffer data between the CPU and either the four-wire digital audio interface or the
DAC/ ADC. It supports single channel input and output data, up to 16 bits wide. When used it can reduce the rate at
which the processor has to generate/process data, and this may allow more efficient operation. Interrupts can be
generated based on fill levels and also FIFO empty and full conditions. Normal configuration of the digital audio
interface or the DAC/ ADC is still required when accessing the data via the FIFO.
When used with the DAC / ADC functions a timing signal is generated by the DAC/ ADC functions to control the
transfer of data to and from the FIFO and the analogue peripherals. The transfers will occur at the sample rate
configured within the DAC / ADC functions.
When the FIFO is linked to the four-wire digital audio interface, timer 2 must be used to generate an internal timing
signal to control the flow of data across the interface. The timer does not require any external pins to be enabled. The
timer should be set up to produce a PWM output with a rising edge generated every time a digital audio transfer is
required. The transfer rate is typically configured to be the audio sample rate, e.g. 8kHz. If the transfer rate is too fast
or slow data will be transferred correctly between the FIFO and the digital audio block.© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 55
19 Intelligent Peripheral Interface
The Intelligent Peripheral (IP) Interface is provided for systems that are more complex, where there is a processor
that requires a wireless peripheral. As an example, the JN5148 may provide a complete JenNet or ZigBee PRO
wireless network interface to a phone, computer, PDA, set-top box or games console. No resources are required from
the main processor compared to a transceiver as the complete wireless protocol may be run on the internal JN5148
CPU. The wireless peripheral may be controlled via one of the UARTs but the IP interface is intended to provide a
high-speed, low-processor-overhead interface.
The intelligent peripheral interface is a SPI slave interface and uses pins shared with other DIO signals. The
interface is designed to allow message passing and data transfer. Data received and transmitted on the IP interface
is copied directly to and from a dedicated area of memory without intervention from the CPU. This memory area, the
intelligent peripheral memory block, contains 64 32-bit word receive and transmit buffers.

The interface functions as a SPI slave. It is possible to select the clock edge of IP_CLK on which data on the IP_DIN
line of the interface is sampled, and the state of data output IP_DOUT is changed. The order of transmission is MSB
first. The IP_DO data output is tri-stated when the device is inactive, i.e. the device is not selected via IP_SEL. An
interrupt output line IP_INT is available so that the JN5148 can indicate to an external master that it has data to
transfer. The interface can be clocked at up to 8MHz
The IP interface signals IP_CLK, IP_DO, IP_DI, IP_SEL, IP_INT are alternate functions of pins DIO14 to 18
respectively.
19.1 Data Transfer Format
Transfers are started by the remote processor asserting the IP_SEL line and terminated by the remote processor deasserting
IP_SEL.
Data transfers are bi-directional and traffic in both directions has a format of status byte, data length byte (of the
number of 32-bit words to transfer) and data packet (from the receive and transmit buffers), as shown in Figure 42
The first byte transferred into the JN5148 is a status byte with the format shown in Table 6. This is followed by a
padding byte that should be set to zero. The first byte output by the JN5148 is a padding byte, that should be ignored,
followed by a status byte with the format shown in Table 6
Bit Field Description
7:2 RSVD Reserved, set to 0
1 TXQ 1: Data queued for transmission
0 RXRDY 1: Buffer ready to receive data
Table 6: IP Status Byte Format56 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
If data is queued for transmission and the recipient has indicated that they are ready for it (RXRDY in incoming status
byte was 1), the next byte to be transmitted is the data length in words (N). If either the JN5148 or the remote
processor has no data to transfer, then the data length should be set to zero. The transaction can be terminated by
the master after the status and padding bytes have been sent if it is not possible to send data in either direction. This
may be because neither party has data to send or because the receiver does not have a buffer available. If the data
length is non-zero, the data in the JN5148 transmit memory buffer is sent, beginning at the start of the buffer. At the
same time that data bytes are being sent from the transmit buffer, the JN5148 receive buffer is being filled with
incoming data, beginning from the start of the buffer.
The remote processor, acting as the master, must determine the larger of its incoming or outgoing data transfers and
deassert IP_SEL when all of the transmit and receive data has been transferred. The data is transferred into or out of
the buffers starting from the lowest address in the buffer, and each word is assembled with the MSB first on the serial
data lines. Following a transaction, IP_SEL must be high (deasserted) for at least 400nsec before a further
transaction can begin.

Figure 42: Intelligent Peripheral Data Transfer Waveforms
The N words of data transferred on the interface are also formatted. The first three bytes, of the first word, must be
zero. These are followed by a one byte length field that must be one less than the data length shown in the data
length field in Figure 42, i.e. N-1. Following this are the (N-1) words of data.
The application running on the JN5148 has high level software functions for sending and receiving data on this
interface. The function of generating and interpreting the individual bytes on the interface is handled by hardware
within the device. The remote processor must generate, and interpret, the signals in the interface. For instance, this
may be done with a configurable SPI master interface.
19.2 JN5148 (Slave) Initiated Data Transfer
To send data, the data is written into either buffer 0 or 1 of the intelligent peripheral memory area. Then the buffer
number is written together with the data length. If the call is successful, the interrupt line IP_INT will signal to the
remote processor that there is a message ready to be sent from the JN5148. When a remote processor starts a
transfer to the JN5148 by deasserting IP_SEL, then IP_INT is deasserted. If the transfer is unsuccessful and the
data is not output then IP_INT is reasserted after the transfer to indicate that data is still waiting to be sent.
The interface can be configured to generate an internal interrupt whenever a transaction completes (for example
IP_SEL becomes inactive after a transfer starts). It is also possible to mask the interrupt. The end of the
transmission can be signalled by an interrupt, or the interface can be polled.
To receive data the interface must be firstly initialised and when this is done, the bit RXRDY sent in the status byte
from the IP block will show that data can be received by the JN5148. Successful data arrival can be indicated by an
interrupt, or the interface can be polled. IP_INT is asserted if the JN5148 is configured to be able to receive, and the
remote processor has previously attempted to send data but the RXRDY indicated that it could not be sent.
To send and receive at the same time, the transmit and receive buffers must be set to be different.
19.3 Remote (Master) Processor Initiated Data Transfer
The remote processor (master) must initiate a transfer to send data to the JN5148 (slave) by asserting the slave
select pin, IP_SEL, and generating its status byte on IP_DI with TXRDY set. After receiving the status byte from the
JN5148, the master should check that the JN5148 has a buffer ready by reading the RXRDY bit of the received
status byte. If the RXRDY bit is 0 indicating that the JN5148 cannot accept data, it must terminate the transfer by
deasserting IP_SEL unless it is receiving data from the JN5148. If the RXRDY bit is 1, indicating that the JN5148 can
accept data, then the master should generate a further 8 clocks on IP_CLK in order to transfer its own message
length on IP_DI. The master must continue clocking the interface until sufficient clocks have been generated to send © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 57
all the data specified in the length field to the JN5148. The master must then deassert IP_SEL to show the transfer
is complete.
The master may initiate a transfer to read data from the JN5148 by asserting the slave select pin, IP_SEL, and
generating its status byte on IP_DI with RXRDY set. After receiving the status byte from the JN5148, it should check
that the JN5148 has a buffer ready by reading the TXRDY bit of the received status byte. If the TXRDY bit is 0,
indicating that the JN5148 does not have data to send, it must terminate the transfer by deasserting IP_SEL unless it
is transmitting data to the JN5148. If the TXRDY bit is 1, indicating that the JN5148 can send data, then the master
must generate a further 8 clocks on IP_CLK in order to receive the message length on IP_DO. The master must
continue clocking the interface until sufficient clocks have been generated to receive all the data specified in the
length field from the JN5148. The master should then deassert IP_SEL to show the transfer is complete.
Data can be sent in both directions at once and the master must ensure both transfers have completed before

Figure 43: Analogue Peripherals
In order to provide good isolation from digital noise, the analogue peripherals are powered by a separate regulator,
supplied from the analogue supply VDD1 and referenced to analogue ground VSSA.
A common reference Vref for the ADC and DAC can be selected between an internal bandgap reference or an
external voltage reference supplied to the VREF pin. Gain settings for the ADC and DAC are independent of each
other.
The ADC and DAC are clocked from a common clock source derived from the 16MHz clock© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 59
20.1 Analogue to Digital Converter
The 12-bit analogue to digital converter (ADC) uses a successive approximation design to perform high accuracy
conversions as typically required in wireless sensor network applications. It has six multiplexed single-ended input
channels: four available externally, one connected to an internal temperature sensor, and one connected to an
internal supply monitoring circuit.
20.1.1 Operation
The input range of the ADC can be set between 0V to either the reference voltage or twice the reference voltage.
The reference can be either taken from the internal voltage reference or from the external voltage applied to the
VREF pin. For example, an external reference of 1.2V supplied to VREF may be used to set the ADC range between
0V and 2.4V.

Table 7 ADC/DAC Maximum Input Range
The input clock to the ADC is 16MHz and can be divided down to 2MHz, 1MHz, 500kHz and 250kHz. During an ADC
conversion the selected input channel is sampled for a fixed period and then held. This sampling period is defined as
a number of ADC clock periods and can be programmed to 2, 4, 6 or 8. The conversion rate is ((3 x Sample period)
+ 14) clock periods. For example for 500kHz conversion with sample period of 2 will be (3 x 2) + 14 = 20 clock
periods, 40usecs or 25kHz. . The ADC can be operated in either a single conversion mode or alternatively a new
conversion can be started as soon as the previous one has completed, to give continuous conversions.
If the source resistance of the input voltage is 1kΩ or less, then the default sampling time of 2 clocks should be used.
The input to the ADC can be modelled as a resistor of 5kΩ(typ) and 10kΩ (max) to represent the on-resistance of the
switches and the sampling capacitor 8pF. The sampling time required can then be calculated, by adding the sensor
source resistance to the switch resistance, multiplying by the capacitance giving a time constant. Assuming normal
exponential RC charging, the number of time constants required to give an acceptable error can be calculated, 7 time
constants gives an error of 0.1%, so for 12-bit accuracy 10 time constants should be the target. For a source with
zero resistance, 10 time constants is 800 nsecs, hence the smallest sampling window of 2 clock periods can be used.

Figure 44 ADC Input Equivalent Circuit
The ADC sampling period, input range and mode (single shot or continuous) are controlled through software.
When the ADC conversion is complete, an interrupt is generated. Alternatively the conversion status can be polled.
When operating in continuous mode, it is recommended that the interrupt is used to signal the end of a conversion,
since conversion times may range from 10 to 152 µsecs. Polling over this period would be wasteful of processor
bandwidth.
To facilitate averaging of the ADC values, which is a common practice in microcontrollers, a dedicated accumulator
has been added, the user can define the accumulation to occur over 2,4,8 or 16 samples. The end of conversion 60 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
interrupt can be modified to occur at the end of the chosen accumulation period, alternatively polling can still be used.
Software can then be used to apply the appropriate rounding and shifting to generate the average value, as well as
setting up the accumulation function.
For detailed electrical specifications, see section 22.3.8.
20.1.2 Supply Monitor
The internal supply monitor allows the voltage on the analogue supply pin VDD1 to be measured. This is achieved
with a potential divider that reduces the voltage by a factor of 0.666, allowing it to fall inside the input range of the
ADC when set with an input range twice the internal voltage reference. The resistor chain that performs the voltage
reduction is disabled until the measurement is made to avoid a continuous drain on the supply.
20.1.3 Temperature Sensor
The on chip temperature sensor can be used either to provide an absolute measure of the device temperature or to
detect changes in the ambient temperature. In common with most on chip temperature sensors, it is not trimmed and
so the absolute accuracy variation is large; the user may wish to calibrate the sensor prior to use. The sensor forces
a constant current through a forward biased diode to provide a voltage output proportional to the chip die temperature
which can then be measured using the ADC. The measured voltage has a linear relationship to temperature as
described in section 22.3.15.
Because this sensor is on chip, any measurements taken must account for the thermal time constants. For example,
if the device just came out of sleep mode the user application should wait until the temperature has stabilised before
taking a measurement.
20.2 Digital to Analogue Converter
The Digital to Analogue Converter (DAC) provides two output channels and is capable of producing voltages of 0 to
Vref or 0 to 2Vref where Vref is selected between the internal reference and the VREF pin, with a resolution of 12-bits
and a minimum conversion time of 10µsecs (2MHz clock).
20.2.1 Operation
The output range of each DAC can be set independently to swing between 0V to either the reference voltage or twice
the reference voltage. The reference voltage is selected from the internal reference or the VREF pin. For example,
an external reference of 0.8V supplied to VREF may be used to set DAC1 maximum output of 0.8V and DAC2
maximum output of 1.6V.
The DAC output amplifier is capable of driving a capacitive load up to that specified in section 22.3.9
Programmable clock periods allow a trade-off between conversion speed and resolution. The full 12-bit resolution is
achieved with the 250kHz clock rate. See section 22.3.9 electrical characteristics, for more details.
The conversion period of the DACs are given by the same formula as the ADC conversion time and so can vary
between 10 and 152uS. The DAC values may be updated at the same time as the ADC is active.
The clock divider ratio, interrupt enable and reference voltage select are all controlled through software, options
common to both the ADC and DAC. The DAC output range and initial value can be set and the subsequent updates
provided by updating only the DAC value. Polling is available to determine if a DAC channel is busy performing a
conversion. The DAC can be disabled which will power down the DAC cell.
Simultaneous conversions with DAC1 and DAC2 are possible. To use both DACs at the same time it is only
necessary to enable them and supply the digital values via the software. The DACs should not be used in single shot
mode, but continuous conversion mode only, in order to maintain a steady output voltage. © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 61
20.3 Comparators
The JN5148 contains two analogue comparators COMP1 and COMP2 that are designed to have true rail-to-rail
inputs and operate over the full voltage range of the analogue supply VDD1. The hysteresis level (common to both
comparators) can be set to a nominal value of 0mV, 10mV, 20mV or 40mV. In addition, the source of the negative
input signal for each comparator (COMP1M and COMP2M) can be set to the internal voltage reference, the output of
DAC1 or DAC2 (COMP1 or COMP2 respectively) or the appropriate external pin. The comparator outputs are routed
to internal registers and can be polled, or can be used to generate interrupts. The comparators can be disabled to
reduce power consumption.
The comparators have a low power mode where the response time of the comparator is slower than normal and is
specified in section 22.3.10. This mode may be used during non-sleep operation however it is particularly useful in
sleep mode to wake up the JN5148 from sleep where low current consumption is important. The wakeup action and
the configuration for which edge of the comparator output will be active are controlled through software. In sleep
mode the negative input signal source, must be configured to be driven from the external pins.62 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
21 Power Management and Sleep Modes
21.1 Operating Modes
Three operating modes are provided in the JN5148 that enable the system power consumption to be controlled
carefully to maximise battery life.
• Active Processing Mode
• Sleep Mode
• Deep Sleep Mode
The variation in power consumption of the three modes is a result of having a series of power domains within the chip
that may be controllably powered on or off.
21.1.1 Power Domains
The JN5148 has the following power domains:
• VDD Supply Domain: supplies the wake-up timers and controller, DIO blocks, Comparators, 32kHz RC and
crystal oscillators. This domain is driven from the external supply (battery) and is always powered. The wake-up
timers and controller, and the 32kHz RC and crystal oscillators may be powered on or off in sleep mode through
software control.
• Digital Logic Domain: supplies the digital peripherals, CPU, ROM, Baseband controller, Modem and Encryption
processor. It is powered off during sleep mode.
• Analogue Domain: supplies the ADC, DACs and the temperature sensor. It is powered off during sleep mode
and may be powered on or off in active processing mode through software control.
• RAM Domain: supplies the RAM during sleep mode to retain the memory contents. It may be powered on or off
for sleep mode through software control.
• Radio Domain: supplies the radio interface. It is powered during transmit and receive and controlled by the
baseband processor. It is powered off during sleep mode.
The current consumption figures for the different modes of operation of the device is given in section 22.2.2.
21.2 Active Processing Mode
Active processing mode in the JN5148 is where all of the application processing takes place. By default, the CPU will
execute at the selected clock speed executing application firmware. All of the peripherals are available to the
application, as are options to actively enable or disable them to control power consumption; see specific peripheral
sections for details.
Whilst in Active processing mode there is the option to doze the CPU but keep the rest of the chip active; this is
particularly useful for radio transmit and receive operations, where the CPU operation is not required therefore saving
power.
21.2.1 CPU Doze
Whilst in doze mode, CPU operation is stopped but the chip remains powered and the digital peripherals continue to
run. Doze mode is entered through software and is terminated by any interrupt request. Once the interrupt service
routine has been executed, normal program execution resumes. Doze mode uses more power than sleep and deep
sleep modes but requires less time to restart and can therefore be used as a low power alternative to an idle loop.
Whilst in CPU doze the current associated with the CPU is not consumed, therefore the basic device current is
reduced as shown in the figures in section 22.2.2.1.
21.3 Sleep Mode
The JN5148 enters sleep mode through software control. In this mode most of the internal chip functions are
shutdown to save power, however the state of DIO pins are retained, including the output values and pull-up enables, © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 63
and this therefore preserves any interface to the outside world. The DAC outputs are placed into a high impedance
state.
When entering into sleep mode, there is an option to retain the RAM contents throughout the sleep period. If the
wakeup timers are not to be used for a wakeup event and the application does not require them to run continually,
then power can be saved by switching off the 32kHz oscillator if selected as the system clock through software
control. The oscillator will be restarted when a wakeup event occurs.
Whilst in sleep mode one of four possible events can cause a wakeup to occur: transitions on DIO inputs, expiry of
wakeup timers, pulse counters maturing or comparator events. If any of these events occur, and the relevant
interrupt is enabled, then an interrupt is generated that will cause a wakeup from sleep. It is possible for multiple
wakeup sources to trigger an event at the same instant and only one of them will be accountable for the wakeup
period. It is therefore necessary in software to remove all other pending wakeup events prior to requesting entry back
into sleep mode; otherwise, the device will re-awaken immediately.
When wakeup occurs, a similar sequence of events to the reset process described in section 6.1 happens, including
the checking of the supply voltage by the Brown Out Detector 6.4. The 32MHz oscillator is started up, once stable
the power to CPU system is enabled and the reset is removed. Software determines that this is a reset from sleep
and so commences with the wakeup process. If RAM contents were held through sleep, wakeup is quicker as the
application program does not have to be reloaded from Flash memory. See section 22.3.6 for wake-up timings.
21.3.1 Wakeup Timer Event
The JN5148 contains two 35-bit wakeup timers that are counters clocked from the 32kHz oscillator, and can be
programmed to generate a wake-up event. Following a wakeup event, the timers continue to run. These timers are
described in section 11.3.
Timer events can be generated from both of the two timers; one is intended for use by the 802.15.4 protocol, the
other being available for use by the Application running on the CPU. These timers are available to run at any time,
even during sleep mode.
21.3.2 DIO Event
Any DIO pin when used as an input has the capability, by detecting a transition, to generate a wake-up event. Once
this feature has been enabled the type of transition can be specified (rising or falling edge). Even when groups of
DIO lines are configured as alternative functions such as the UARTs or Timers etc, any input line in the group can still
be used to provide a wakeup event. This means that an external device communicating over the UART can wakeup
a sleeping device by asserting its RTS signal pin (which is the CTS input of the JN5148).
21.3.3 Comparator Event
The comparator can generate a wakeup interrupt when a change in the relative levels of the positive and negative
inputs occurs. The ability to wakeup when continuously monitoring analogue signals is useful in ultra-low power
applications. For example, the JN5148 can remain in sleep mode until the voltage drops below a threshold and then
be woken up to deal with the alarm condition.
21.3.4 Pulse Counter
The JN5148 contains two 16 bit pulse counters that can be programmed to generate a wake-up event. Following the
wakeup event the counters will continue to operate and therefore no pulse will be missed during the wake-up
process. These counters are described in section 12.
To minimise sleep current it is possible to disable the 32K RC oscillator and still use the pulse counters to cause a
wake-up event, provided debounce mode is not required.
21.4 Deep Sleep Mode
Deep sleep mode gives the lowest power consumption. All switchable power domains are off and certain functions in
the VDD supply power domain, including the 32kHz oscillator are stopped. This mode can be exited by a power
down, a hardware reset on the RESETN pin, or a DIO event. The DIO event in this mode causes a chip reset to
occur.64 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

The chip is available in three different reel quantities:
• 500 on 180mm reel
• 1000 on 180mm reel
• 2500 on 330mm reel
Where this Data Sheet is denoted as “Advanced” or “Preliminary”, devices will be either Engineering Samples or
Prototypes. Devices of this status are marked with an Rx suffix after the ROM identifier to identify the revision of
silicon during these product phases - for example JN5148-001R1-T.
The Standard Supply Multiple (SSM) for Engineering Samples or Prototypes is 50 units with a maximum of 250 units.
If the quantity of Engineering Samples or Prototypes ordered is less than a reel quantity, then these will be shipped in
tape form only, with no reel and will not be dry packaged in a moisture sensitive environment.
The SSM for Production status devices is one reel, all reels are dry packaged in a moisture sensitive bag see A.5.3.84 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013

B.1 Crystal Oscillators
This section covers some of the general background to crystal oscillators, to help the user make informed decisions
concerning the choice of crystal and the associated capacitors.
B.1.1 Crystal Equivalent Circuit
Cs
Lm Rm Cm
C1 C2
Where Cm is the motional capacitance
Lm is the motional inductance. This together with Cm defines the oscillation frequency (series)
Rm is the equivalent series resistance ( ESR ).
CS is the shunt or package capacitance and this is a parasitic
B.1.2 Crystal Load Capacitance
The crystal load capacitance is the total capacitance seen at the crystal pins, from all sources. As the load
capacitance (CL) affects the oscillation frequency by a process known as ‘pulling’, crystal manufacturers specify the
frequency for a given load capacitance only. A typical pulling coefficient is 15ppm/pF, to put this into context the
maximum frequency error in the IEEE802.15.4 specification is +/-40ppm for the transmitted signal. Therefore, it is
important for resonance at 32MHz exactly, that the specified load capacitance is provided.
The load capacitance can be calculated using:
CL =

Total capacitance CT1 = C1 + C1P + C1in
Where C1 is the capacitor component
C1P is the PCB parasitic capacitance. With the recommended layout this is about 1.6pF
C1in is the on-chip parasitic capacitance and is about 1.4pF typically.
Similarly for CT 2
Hence for a 9pF load capacitance, and a tight layout the external capacitors should be 15pF© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 89
B.1.3 Crystal ESR and Required Transconductance
The resistor in the crystal equivalent circuit represents the energy lost. To maintain oscillation, power must be
supplied by the amplifier, but how much? Firstly, the Pi connected capacitors C1 and C2 with CS from the crystal,
apply an impedance transformation to Rm, when viewed from the amplifier. This new value is given by:
2
ˆ
+ = L
S L m m
C
C C R R
The amplifier is a transconductance amplifier, which takes a voltage and produces an output current. The amplifier
together with the capacitors C1 and C2, form a circuit, which provides a negative resistance, when viewed from the
crystal. The value of which is given by:
2
1× 2 ×ω = T T
m
NEG
C C
g R
Where gm is the transconductance
ω is the frequency in rad/s
Derivations of these formulas can be easily found in textbooks.
In order to give quick and reliable oscillator start-up, a common rule of thumb is to set the amplifier negative
resistance to be a minimum of 4 times the effective crystal resistance. This gives

This can be used to give an equation for the required transconductance.

Example: Using typical 32MHz crystal parameters of Rm =40Ω, CS =1pF and CT1 =CT 2 =18pF ( for a load
capacitance of 9pF), the equation above gives the required transconductance ( gm ) as 2.59mA/V. The JN5148 has a
typical value for transconductance of 4.3mA/V
The example and equation illustrate the trade-off that exists between the load capacitance and crystal ESR. For
example, a crystal with a higher load capacitance can be used, but the value of max. ESR that can be tolerated is
reduced. Also note, that the circuit sensitivity to external capacitance [ C1 , C2 ] is a square law.
Meeting the criteria for start-up is only one aspect of the way these parameters affect performance, they also affect
the time taken during start-up to reach a given, (or full), amplitude. Unfortunately, there is no simple mathematical
model for this, but the trend is the same. Therefore, both a larger load capacitance and larger crystal ESR will give a
longer start-up time, which has the disadvantages of reduced battery life and increased latency. 90 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013
B.2 32MHz Oscillator
The JN5148 contains the necessary on-chip components to build a 32 MHz reference oscillator with the addition of
an external crystal resonator, two tuning capacitors. The schematic of these components are shown in Figure 58.
The two capacitors, C1 and C2, will typically be 15pF ±5% and use a COG dielectric. For a detailed specification of
the crystal required and factors affecting C1 and C2 see Appendix B.1. As with all crystal oscillators the PCB layout is
especially important, both to keep parasitic capacitors to a minimum and to reduce the possibility of PCB noise being
coupled into the oscillator.

As is stated above, not all combinations of crystal load capacitance and ESR are valid, and as explained in Appendix
B.1.3 there is a trade-off that exists between the load capacitance and crystal ESR to achieve reliable performance.
For this reason, we recommend that for a 9pF load capacitance crystals be specified with a maximum ESR of 40
ohms. For lower load capacitances the recommended maximum ESR rises, for example, CL=7pF the max ESR is 61
ohms. For the lower cost crystals in the large HC49 package, a load capacitance of 9 or 10pF is widely available and
the max ESR of 30 ohms specified by many manufacturers is acceptable. Also available in this package style, are
crystals with a load capacitance of 12pF, but in this case the max ESR required is 25 ohms or better.
Below is measurement data showing the variation of the crystal oscillator amplifier transconductance with
temperature and supply voltage, notice how small the variation is. Circuit techniques have been used to apply
compensation, such that the user need only design for nominal conditions.

B.3 32kHz Oscillator
In order to obtain more accurate sleep periods, the JN5148 contains the necessary on-chip components to build an
optional 32kHz oscillator with the addition of an external 32.768kHz crystal and two tuning capacitors. The crystal
should be connected between XTAL32K_IN and XTAL32K_OUT (DIO9 and DIO10), with two equal capacitors to
ground, one on each pin. The schematic of these components are shown in Figure 59. The two capacitors, C1 and
C2, will typically be in the range 10 to 22pF ±5% and use a COG dielectric. As with all crystal oscillators the PCB
layout is especially important, both to keep parasitic capacitors to a minimum and to reduce the possibility of PCB
noise being coupled into the oscillator.
XTAL32K_IN XTAL32K_OUT
JN5148
Figure 59: 32kHz crystal oscillator connections
The electrical specification of the oscillator can be found in 22.3.12. The oscillator cell is flexible and can operate with
a range of commonly available 32kHz crystals with load capacitances from 6 to 12.5p, and ESR up to 80KΩ. It
achieves this by using automatic gain control (AGC), which senses the signal swing. As explained in Appendix B.1.3
there is a trade-off that exists between the load capacitance and crystal ESR to achieve reliable performance. The
use of an AGC function allows a wider range of crystal load capacitors and ESR’s to be accommodated than would
otherwise be possible. However, this benefit does mean the supply current varies with the supply voltage (VDD),
value of the total capacitance at each pin, and the crystal ESR. This is described in the table and graphs below.

B.4.2 PCB Design and Reflow Profile
PCB and land pattern designs are key to the reliability of any electronic circuit design.
The Institute for Interconnecting and Packaging Electronic Circuits (IPC) defines a number of standards for electronic
devices. One of these is the "Surface Mount Design and Land Pattern Standard" IPC-SM-782 [3], commonly referred
to as “IPC782". This specification defines the physical packaging characteristics and land patterns for a range of
surface mounted devices. IPC782 is also a useful reference document for general surface mount design techniques,
containing sections on design requirements, reliability and testability. NXP strongly recommends that this be referred
to when designing the PCB.
The suggested reflow profile is shown in Figure 61. The specific paste manufacturers guidelines on peak flow
temperature, soak times, time above liquidus and ramp rates should also be referenced.

1 Introduction
The JN516x is an IEEE802.15.4 wireless microcontroller that provides a fully integrated solution for applications using
the IEEE802.15.4 standard in the 2.4 - 2.5GHz ISM frequency band [1], including Zigbee PRO, ZigBee Smart Energy,
ZigBee LightLink, RF4CE and JenNet-IP. There are 3 versions in the range, differing only by memory configuration
JN5161-001: 64kB Flash, 8kB RAM, 4 kB EEPROM, suitable for IEEE802.15.4 and RF4CE applications
JN5164-001: 160kB Flash, 32kB RAM, 4 kB EEPROM suitable for Jennet-IP, IEEE802.15.4 and RF4CE applications
JN5168-001: 256kB Flash, 32kB RAM, 4 kB EEPROM suitable for all applications
Applications that transfer data wirelessly tend to be more complex than wired ones. Wireless protocols make
stringent demands on frequencies, data formats, timing of data transfers, security and other issues. Application
development must consider the requirements of the wireless network in addition to the product functionality and user
interfaces. To minimise this complexity, NXP provides a series of software libraries and interfaces that control the
transceiver and peripherals of the JN516x. These libraries and interfaces remove the need for the developer to
understand wireless protocols and greatly simplifies the programming complexities of power modes, interrupts and
hardware functionality.
In view of the above, it is not necessary to provide the register details of the JN516x in the datasheet.
The device includes a Wireless Transceiver, RISC CPU, on chip memory and an extensive range of peripherals.
1.1 Wireless Transceiver
The Wireless Transceiver comprises a 2.45GHz radio, a modem, a baseband controller and a security coprocessor.
In addition, the radio also provides an output to control transmit-receive switching of external devices such as power
amplifiers allowing applications that require increased transmit power to be realised very easily. Appendix B.4,
describes a complete reference design including Printed Circuit Board (PCB) design and Bill Of Materials (BOM).
The security coprocessor provides hardware-based 128-bit AES-CCM* modes as specified by the IEEE802.15.4
2006 standard. Specifically this includes encryption and authentication covered by the MIC –32/-64/-128, ENC and
ENC-MIC –32/-64/-128 modes of operation.
The transceiver elements (radio, modem and baseband) work together to provide IEEE802.15.4 (2006) MAC and
PHY functionality under the control of a protocol stack. Applications incorporating IEEE802.15.4 functionality can be
developed rapidly by combining user-developed application software with a protocol stack library.
1.2 RISC CPU and Memory
A 32-bit RISC CPU allows software to be run on-chip, its processing power being shared between the IEEE802.15.4
MAC protocol, other higher layer protocols and the user application. The JN516x has a unified memory architecture,
code memory, data memory, peripheral devices and I/O ports are organised within the same linear address space.
The device contains up to 256kbytes of Flash, up to 32kbytes of RAM and 4kbytes EEPROM . © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 7

The PCB schematic and layout rules detailed in Appendix B.4
must be followed. Failure to do so will likely result in the
JN516x failing to meet the performance specification detailed
herein and worst case may result in device not functioning in
the end application.12 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
2.2 Pin Descriptions
2.2.1 Power Supplies
The device is powered from the VDD1 and VDD2 pins, each being decoupled with a 100nF ceramic capacitor. VDD1
is the power supply to the analogue circuitry; it should be decoupled to ground. VDD2 is the power supply for the
digital circuitry; and should also be decoupled to ground. In addition, a common 10µF tantalum capacitor is required
for low frequencies. Decoupling pins for the internal 1.8V regulators are provided which each require a100nF
capacitor located as close to the device as practical. VB_SYNTH, VB_RAM and VB_DIG require only a 100nF
capacitor. VB_RF and VB_RF2 should be connected together as close to the device as practical, and require one
100nF capacitor and one 47pF capacitor. The pin VB_VCO requires a 10nF capacitor. Refer to B.4.1 for schematic
diagram.
VSSA (paddle), VSS1, VSS2 are the ground pins.
Users are strongly discouraged from connecting their own circuits to the 1.8v regulated supply pins, as the regulators
have been optimised to supply only enough current for the internal circuits.
2.2.2 Reset
RESETN is an active low reset input pin that is connected to a 500kΩ internal pull-up resistor. It may be pulled low
by an external circuit. Refer to Section 6.2 for more details.
2.2.3 32MHz Oscillator
A crystal is connected between XTAL_IN and XTAL_OUT to form the reference oscillator, which drives the system
clock. A capacitor to analogue ground is required on each of these pins. Refer to Section 5.1 for more details. The
32MHz reference frequency is divided down to 16MHz and this is used as the system clock throughout the device.
2.2.4 Radio
The radio is a single ended design, requiring a capacitor and just two inductors to match to 50Ω microstrip line to the
RF_IN pin.
An external resistor (43kΩ) is required between IBIAS and analogue ground (paddle) to set various bias currents and
references within the radio.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 13
2.2.5 Analogue Peripherals
The ADC requires a reference voltage to use as part of its operation. It can use either an internal reference voltage
or an external reference connected to VREF. This voltage is referenced to analogue ground and the performance of
the analogue peripherals is dependent on the quality of this reference.
There are four ADC inputs and a pair of comparator inputs. ADC1 has a designated input pin but ADC2 uses the
same pin as VREF, invalidating its use as an ADC pin when an external reference voltage is required. The remaining
2 ADC channels are shared with the digital I/Os DIO0 and DIO1 and connect to pins 16 and 17. When these two
ADC channels are selected, the corresponding DIOs must be configured as Inputs with their pull-ups disabled.
Similarly, the comparator shares pins 1 and 2 with DIO16 and DIO17, so when the comparator is selected these pins
must be configured as Inputs with their pull-ups disabled. The analogue I/O pins on the JN516x can have signals
applied up to 0.3v higher than VDD1. A schematic view of the analogue I/O cell is shown in Figure 3. Figure 4
demonstrates a special case, where a digital I/O pin doubles as an input to analogue devices. This applies to ADC3,
ADC4, COMP1P and COMP1M.
In reset, sleep and deep sleep, the analogue peripherals are all off. In sleep, the comparator may optionally be used
as a wakeup source.
Unused ADC and comparator inputs should not be left unconnected, for example connected to analogue ground.

2.2.6 Digital Input/Output
For the DC properties of these pins see Section 19.2.3.
When used in their primary function all Digital Input/Output pins are bi-directional and are connected to weak internal
pull up resistors (50kΩ nominal) that can be disabled. When used in their secondary function (selected when the
appropriate peripheral block is enabled through software library calls), their direction is fixed by the function. The pull
up resistor is enabled or disabled independently of the function and direction; the default state from reset is enabled.
A schematic view of the digital I/O cell is in Figure 4. The dotted lines through resistor RESD represent a path that
exists only on DIO0, DIO1, DIO16 and DIO17 which are also inputs to the ADC (ADC3, ADC4) and Comparator
(COMP1P, COMP1M) respectively. To use these DIO pins for their analogue functions, the DIO must be set as an
Input with its pull-up resistor, RPU, disabled.14 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

Figure 4: DIO Pin Equivalent Schematic
In reset, the digital peripherals are all off and the DIO pins are set as high-impedance inputs. During sleep and deep
sleep, the DIO pins retain both their input/output state and output level that was set as sleep commences. If the DIO
pins were enabled as inputs and the interrupts were enabled then these pins may be used to wake up the JN516x
from sleep.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 15
3 CPU
The CPU of the JN516x is a 32-bit load and store RISC processor. It has been architected for three key
requirements:
• Low power consumption for battery powered applications
• High performance to implement a wireless protocol at the same time as complex applications
• Efficient coding of high-level languages such as C provided with the Software Developers Kit
It features a linear 32-bit logical address space with unified memory architecture, accessing both code and data in the
same address space. Registers for peripheral units, such as the timers, UART and the baseband processor are also
mapped into this space.
The CPU has access to a block of 15 32-bit General-Purpose (GP) registers together with a small number of special
purpose registers which are used to store processor state and control interrupt handling. The contents of any GP
register can be loaded from or stored to memory, while arithmetic and logical operations, shift and rotate operations,
and signed and unsigned comparisons can be performed either between two registers and stored in a third, or
between registers and a constant carried in the instruction. Operations between general or special-purpose registers
execute in one cycle while those that access memory require a further cycle to allow the memory to respond.
The instruction set manipulates 8, 16 and 32-bit data; this means that programs can use objects of these sizes very
efficiently. Manipulation of 32-bit quantities is particularly useful for protocols and high-end applications allowing
algorithms to be implemented in fewer instructions than on smaller word-size processors, and to execute in fewer
clock cycles. In addition, the CPU supports hardware Multiply that can be used to efficiently implement algorithms
needed by Digital Signal Processing applications.
The instruction set is designed for the efficient implementation of high-level languages such as C. Access to fields in
complex data structures is very efficient due to the provision of several addressing modes, together with the ability to
be able to use any of the GP registers to contain the address of objects. Subroutine parameter passing is also made
more efficient by using GP registers rather than pushing objects onto the stack. The recommended programming
method for the JN516x is by using C, which is supported by a software developer kit comprising a C compiler, linker
and debugger.
The CPU architecture also contains features that make the processor suitable for embedded, real-time applications.
In some applications, it may be necessary to use a real-time operating system to allow multiple tasks to run on the
processor. To provide protection for device-wide resources being altered by one task and affecting another, the
processor can run in either supervisor or user mode, the former allowing access to all processor registers, while the
latter only allows the GP registers to be manipulated. Supervisor mode is entered on reset or interrupt; tasks starting
up would normally run in user mode in a RTOS environment.
Embedded applications require efficient handling of external hardware events. Exception processing (including reset
and interrupt handling) is enhanced by the inclusion of a number of special-purpose registers into which the PC and
status register contents are copied as part of the operation of the exception hardware. This means that the essential
registers for exception handling are stored in one cycle, rather than the slower method of pushing them onto the
processor stack. The PC is also loaded with the vector address for the exception that occurred, allowing the handler
to start executing in the next cycle.
To improve power consumption a number of power-saving modes are implemented in the JN516x, described more
fully in Section 18. One of these modes is the CPU doze mode; under software control, the processor can be shut
down and on an interrupt it will wake up to service the request. Additionally, it is possible under software control, to
set the speed of the CPU to 1, 2, 4, 8, 16 or 32MHz. This feature can be used to trade-off processing power against
current consumption.16 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

Figure 5: JN5168 Memory Map
4.1 FLASH
The embedded Flash consists of 2 parts: an 8K region used for holding boot code, and a 256K region (JN5168) used
for application code. The sector size of the application code is always 32K, for any size of Flash memory. The
maximum number of write cycles or endurance is, 10k guaranteed and typically 100k, while the data retention is
guaranteed for at least 10 years. The boot code region is pre-programmed by NXP on supplied parts, and contains
code to handle reset, interrupts and other events (see section 7). It also contains a Flash Programming Interface to
allow interaction with the PC-based Flash Programming Utility which allows user code compiled using the supplied
SDK to be programmed into the Application space. For further information, refer to the Flash Programmer User
Guide.[9]. The memory can be erased by a single or multiple sectors and written to in units of 256 bytes, known as
pagewords.
4.2 RAM
The JN516x devices contain up to 32Kbytes of high speed RAM, which can be accessed by the CPU in a single clock
cycle. It is primarily used to hold the CPU Stack together with program variables and data. If necessary, the CPU can
execute code contained within the RAM (although it would normally just execute code directly from the embedded
Flash). Software can control the power supply to the RAM allowing the contents to be maintained during a sleep
period when other parts of the device are un-powered, allowing a quicker resumption of processing once woken.
4.3 OTP Configuration Memory
The JN516x devices contain a quantity of One Time Programmable (OTP) memory as part of the embedded Flash
(Index Sector). This can be used to securely hold such things as a user 64-bit MAC address and a 128-bit AES
security key. By default the 64-bit MAC address is pre-programmed by NXP on supplied parts; however customers © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 17
can use their own MAC address and override the default one. The user MAC address and other data can be written
to the OTP memory using the Flash programmer [9]. Details on how to obtain and install MAC addresses can be
found in the Flash Programmer User Guide. In addition 384bits are available, organised as three 128bit words, for
customer use for storage of configuration or other information.
4.4 EEPROM
The JN516x devices contain 4Kbytes of EEPROM. The maximum number of write cycles or endurance is, 100k
guaranteed and 1M typically while the data retention is guaranteed for at least 20 years. (The Persistent Data
Manager, includes a wear-levelling algorithm which can help to extend the endurance.) This non-volatile memory is
primarily used to hold persistent data generated from such things as the Network Stack software component (e.g.
network topology, routing tables). As the EEPROM holds its contents through sleep and reset events, this means
more stable operation and faster recovery is possible after outages. Access to the EEPROM is via registers mapped
into the Flash and EEPROM Registers region of the address map. The memory can be erased by a single or multiple
pages of 64 bytes. It can be written to in single or multiple bytes up to 64 bytes. The customer may use part of the
EEPROM to store its own data if desired by interfacing with the Persistent Data Manager. Optionally the PDM can
also store data in an external memory. For further information, please read - JenOS User Guide [12].
4.5 External Memory
An optional external serial non-volatile memory (eg Flash or EEPROM) with a SPI interface may be used to provide
additional storage for program code, such as a new code image or further data for the device when external power is
removed. The memory can be connected to the SPI Master interface using select line SPISEL0 (see fig 6 for details)

Figure 6: Connecting External Serial Memory
The contents of the external serial memory may be encrypted. The AES security processor combined with a user
programmable 128-bit encryption key is used to encrypt the contents of the external memory. The encryption key is
stored in the flash memory index section. When bootloading program code from external serial memory, the JN516x
automatically accesses the encryption key to execute the decryption process, user program code does not need to
handle any of the decryption process; it is transparent. For more details, including the how the program code encrypts
data for the external memory, see the application note Boot Loader Operation. [8]
4.6 Peripherals
All peripherals have their registers mapped into the memory space. Access to these registers requires 3 peripheral
clock cycles. Applications have access to the peripherals through the software libraries that present a high-level view
of the peripheral’s functions through a series of dedicated software routines. These routines provide both a tested
method for using the peripherals and allow bug-free application code to be developed more rapidly. For details, see
Peripherals API User Guide [4].
4.7 Unused Memory Addresses
Any attempt to access an unpopulated memory area will result in a bus error exception (interrupt) being generated.18 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
5 System Clocks
Two system clocks are used to drive the on-chip subsystems of the JN516x. The wake-up timers are driven from a
low frequency clock (notionally 32kHz). All other subsystems (transceiver, processor, memory and digital and
analogue peripherals) are driven by a high-speed clock (notionally 32MHz), or a divided-down version of it.
The high-speed clock is either generated by the accurate crystal-controlled oscillator (32MHz) or the less accurate
high-speed RC oscillator ( 27-32MHz calibrated). The low-speed clock is either generated by the accurate crystalcontrolled
oscillator (32.768kHz), the less accurate RC oscillator (centered on 32kHz) or can be supplied externally
5.1 High-Speed (32MHz) System Clock
The selected high-speed system clock is used directly by the radio subsystem, whereas a divided-by-two version is
used by the remainder of the transceiver and the digital and analogue peripherals. The direct or divided down version
of the clock is used to drive the processor and memories (32, 16, 8, 4, 2 or 1MHz).

Figure 7 System and CPU Clocks
Crystal oscillators are generally slow to start. Hence to provide a fast start-up following a sleep cycle or reset, the fast
RC oscillator is always used as the initial source for the high-speed system clock. The oscillator starts very quickly
and will run at 25-32MHz (uncalibrated) or 32MHz +/-5% (calibrated). Although this means that the system clock will
be running at an undefined frequency (slightly slower or faster than nominal), this does not prevent the CPU and
Memory subsystems operating normally, so the program code can execute. However, it is not possible to use the
radio or UARTs, as even after calibration (initiated by the user software calling an API function) there is still a +/-5%
tolerance in the clock rate over voltage and temperature. Other digital peripherals can be used (eg SPI Master/Slave),
but care must be taken if using Timers due to the clock frequency inaccuracy.
Further details of the High-Speed RC Oscillator can be found in section 19.3.11.
On wake-up from sleep, the JN516x uses the Fast RC oscillator. It can then either:
• Automatically switch over to use the 32MHz clock source when it has started up.
• Continue to use the fast RC oscillator until software triggers the switch-over to the 32MHz clock source, for
example when the radio is required.
• Continue to use the RC oscillator until the device goes back into one of the sleep modes.
The use of the fast RC Oscillator at wake-up means there is no need to wait for the 32MHz crystal oscillator to
stabilise Consequently, the application code will start executing quickly using the clock from the high-speed RC
oscillator.
5.1.1 32MHz Crystal Oscillator
The JN516x contains the necessary on chip components to build a 32MHz reference oscillator with the addition of an
external crystal resonator and two tuning capacitors. The schematic of these components are shown in Figure 8.
The two capacitors, C1 and C2, should typically be 15pF and use a COG dielectric. Due to the small size of these
capacitors, it is important to keep the traces to the external components as short as possible. The on chip
transconductance amplifier is compensated for temperature variation, and is self-biasing by means of the internal
resistor R1. This oscillator provides the frequency reference for the radio and therefore it is essential that the
reference PCB layout and BOM are carefully followed. The electrical specification of the oscillator can be found in © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 19
Section 19.3.11. Please refer to Appendix B for development support with the crystal oscillator circuit. The oscillator
includes a function which flags when the amplitude of oscillation has reached a satisfactory level for full operation,
and this is checked before the source of the high-speed system clock is changed to the 32MHz crystal oscillator

C1 C2
XTALIN R1
JN516x
Figure 8: 32MHz Crystal Oscillator Connections
For operation over the extended temperature range, 85 to 125 deg C, special care is required; this is because the
temperature characteristics of crystal resonators are generally in excess of +/-40ppm frequency tolerance defined by
the IEEE802.15.4 standard. The oscillator cell contains additional circuitry to compensate for the poor performance of
the crystal resonators above 100 deg C. Full details, including the software API function, can be found in the
application note JN516x Temperature-dependent Operating Guidelines [2]
5.1.2 High-Speed RC Oscillator
An on-chip High-Speed RC oscillator is provided in addition to the 32MHz crystal oscillator for two purposes, to allow
a fast start-up from reset or sleep and to provide a lower current alternative to the crystal oscillator for non-timing
critical applications. By default the oscillator will run at 27MHz typically with a wide tolerance. It can be calibrated,
using a software API function, which will result in a nominal frequency of 32MHz with a +/-1.6% tolerance at 3v and
25 deg C. However, it should be noted that over the full operating range of voltage and temperature this will increase
to +/-5%. The calibration information is retained through speed cycles and when the oscillator is disabled, so typically
the calibration function only needs to be called once. No external components are required for this oscillator. The
electrical specification of the oscillator can be found in Section 19.3.12.
5.2 Low-speed (32kHz) System Clock
The 32kHz system clock is used for timing the length of a sleep period (see Section 18). The clock can be selected
from one of three sources through the application software:
• 32kHz RC Oscillator
• 32kHz Crystal Oscillator
• 32kHz External Clock
Upon a chip reset or power-up the JN516x defaults to using the internal 32kHz RC Oscillator. If another clock source
is selected then it will remain in use for all 32kHz timing until a chip reset is performed.
5.2.1 32kHz RC Oscillator
The internal 32kHz RC oscillator requires no external components. The internal timing components of the oscillator
have a wide tolerance due to manufacturing process variation and so the oscillator runs nominally at 32kHz -10%
/+40%. To make this useful as a timing source for accurate wakeup from sleep, a frequency calibration factor derived
from the more accurate 16MHz clock may be applied. The calibration factor is derived through software, details can
be found in Section 11.3.1. Software must check that the 32kHz RC oscillator is running before using it. The oscillator
has a default current consumption of around 0.5uA, optionally this can be reduced to 0.375uA, however, the 20 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
calibrated accuracy and temperature coefficient will be worse as a consequence. For detailed electrical
specifications, see Section 19.3.9.
5.2.2 32kHz Crystal Oscillator
In order to obtain more accurate sleep periods, the JN516x contains the necessary on-chip components to build a
32kHz oscillator with the addition of an external 32.768kHz crystal and two tuning capacitors. The crystal should be
connected between 32KXTALIN and 32KXTALOUT (DIO9 and DIO10), with two equal capacitors to ground, one on
each pin. Due to the small size of the capacitors, it is important to keep the traces to the external components as
short as possible.
The electrical specification of the oscillator can be found in Section 19.3.10. The oscillator cell is flexible and can
operate with a range of commonly available 32.768kHz crystals with load capacitances from 6 to 12.5pF. However,
the maximum ESR of the crystal and the supply current are both functions of the actual crystal used, see Appendix
B.1 for more details.

JN516x
Figure 9: 32kHz Crystal Oscillator Connections
5.2.3 32kHz External Clock
An externally supplied 32kHz reference clock on the 32KXTALIN input (DIO9) may be provided to the JN516x. This
would allow the 32kHz system clock to be sourced from a very stable external oscillator module, allowing more
accurate sleep cycle timings compared to the internal RC oscillator. (See Section 19.2.3)© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 21
6 Reset
A system reset initialises the device to a pre-defined state and forces the CPU to start program execution from the
reset vector. The reset process that the JN516x goes through is as follows.
When power is first applied or when the external reset is released, the High-Speed RC oscillator and 32MHz crystal
oscillator are activated. After a short wait period (13µsec approx) while the High-Speed RC starts up, and so long as
the supply voltage satisfies the default Supply Voltage Monitor (SVM) threshold (2.0V+0.045V hysteresis), the
internal 1.8V regulators are turned on to power the processor and peripheral logic. The regulators are allowed to
stabilise (about 15us) followed by a further wait (150usec approx) to allow the Flash and EEPROM bandgaps to
stabilise and allow their initialisation, including reading the user SVM threshold from the Flash. This is applied to the
SVM and, after a brief pause (approx 2.5usec), the SVM is checked again. If the supply is above the new SVM
threshold, the CPU and peripheral logic is released from reset and the CPU starts to run code beginning at the reset
vector. This runs the bootloader code contained within the flash, which looks for a valid application to run, first from
the internal flash and then from any connected external serial memory over the SPI Master interface. Once found,
required variables are initialised in RAM before the application is called at its AppColdStart entry point. More details
on the bootloader can be found in the application note - Boot Loader Operation. [8]
The JN516x has five sources of reset:
• Internal Power-on / Brown-out Reset (BOR)
• External Reset
• Software Reset
• Watchdog timer
• Supply Voltage detect
Note: When the device exits a reset condition, device operating
parameters (voltage, frequency, temperature, etc.) must be met to ensure
operation. If these conditions are not met, then the device must be held in
reset until the operating conditions are met. (See Section 19.3)
6.1 Internal Power-On / Brown-out Reset (BOR)
For the majority of applications the internal power-on reset is capable of generating the required reset signal. When
power is applied to the device, the power-on reset circuit monitors the rise of the VDD supply. When the VDD
reaches the specified threshold, the reset signal is generated. This signal is held internally until the power supply and
oscillator stabilisation time has elapsed, when the internal reset signal is then removed and the CPU is allowed to
run.
The BOR circuit has the ability to reject spikes on the VDD rail to avoid false triggering of the reset module. Typically
for a negative going square pulse of duration 1uS, the voltage must fall to 1.2v before a reset is generated. Similarly
for a triangular wave pulse of 10us width, the voltage must fall to 1.3v before causing a reset. The exact
characteristics are complex and these are only examples.
Internal RESET
VDD
Figure 10: Internal Power-on Reset
When the supply drops below the power on reset ‘falling’ threshold, it will re-trigger the reset. If necessary, use of the
external reset circuit show in Figure 11 is suggested. 22 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

Figure 11: External Reset Generation
The external resistor and capacitor provide a simple reset operation when connected to the RESETN pin but are not
neccessary.
6.2 External Reset
An external reset is generated by a low level on the RESETN pin. Reset pulses longer than the minimum pulse width
will generate a reset during active or sleep modes. Shorter pulses are not guaranteed to generate a reset. The
JN516x is held in reset while the RESETN pin is low. When the applied signal reaches the Reset Threshold Voltage
(VRST) on its positive edge, the internal reset process starts.
The JN516x has an internal 500kΩ pull-up resistor connect to the RESETN pin. The pin is an input for an external
reset only. By holding the RESETN pin low, the JN516x is held in reset, resulting in a typical current of 6uA.

Figure 12: External Reset
6.3 Software Reset
A system reset can be triggered at any time through software control, causing a full chip reset and invalidating the
RAM contents. For example this can be executed within a user’s application upon detection of a system failure.
6.4 Supply Voltage Monitor (SVM)
An internal Supply Voltage Monitor (SVM) is used to monitor the supply voltage to the JN516x; this can be used
whilst the device is awake or is in CPU doze mode. Dips in the supply voltage below a variable threshold can be
detected and can be used to cause the JN516x to perform a chip reset. Equally, dips in the supply voltage can be © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 23
detected and used to cause an interrupt to the processor, when the voltage either drops below the threshold or rises
above it.
The supply voltage detect is enabled by default from power-up and can extend the reset during power-up. This will
keep the CPU in reset until the voltage exceeds the SVM threshold voltage. The threshold voltage is configurable to
1.95V, 2.0V, 2.1V, 2.2V, 2.3V, 2.4V, 2.7V and 3.0V and is controllable by software. From power-up the threshold is
set by a setting within the flash and the default chip configuration is for the 2.0V threshold. It is expected that the
threshold is set to the minimum needed by the system..
6.5 Watchdog Timer
A watchdog timer is provided to guard against software lockups. It operates by counting cycles of the high-speed RC
system clock. A pre-scaler is provided to allow the expiry period to be set between typically 8ms and 16.4 seconds
(dependent on high-speed RC accuracy: +30%, -15%). Failure to restart the watchdog timer within the pre-configured
timer period will cause a chip reset to be performed. A status bit is set if the watchdog was triggered so that the
software can differentiate watchdog initiated resets from other resets, and can perform any required recovery once it
restarts. Optionally, the watchdog can cause an exception rather than a reset, this preserves the state of the memory
and is useful for debugging.
After power up, reset, start from deep sleep or start from sleep, the watchdog is always enabled with the largest
timeout period and will commence counting as if it had just been restarted. Under software control the watchdog can
be disabled. If it is enabled, the user must regularly restart the watchdog timer to stop it from expiring and causing a
reset. The watchdog runs continuously, even during doze, however the watchdog does not operate during sleep or
deep sleep, or when the hardware debugger has taken control of the CPU. It will recommence automatically if
enabled once the debugger un-stalls the CPU. 24 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
7 Interrupt System
The interrupt system on the JN516x is a hardware-vectored interrupt system. The JN516x provides several interrupt
sources, some associated with CPU operations (CPU exceptions) and others which are used by hardware in the
device. When an interrupt occurs, the CPU stops executing the current program and loads its program counter with a
fixed hardware address specific to that interrupt. The interrupt handler or interrupt service routine is stored at this
location and is run on the next CPU cycle. Execution of interrupt service routines is always performed in supervisor
mode. Interrupt sources and their vector locations are listed in Table 1 below:
Interrupt Source Vector Location Interrupt Definition
Bus error 0x08 Typically cause by an attempt to access an invalid address or a
disabled peripheral
Tick timer 0x0e Tick timer interrupt asserted
Alignment error 0x14 Load/store address to non-naturally-aligned location
Illegal instruction 0x1a Attempt to execute an unrecognised instruction
Hardware interrupt 0x20 interrupt asserted
System call 0x26 System call initiated by b.sys instruction
Trap 0x2c caused by the b.trap instruction or the debug unit
Reset 0x38 Caused by software or hardware reset.
Stack Overflow 0x3e Stack overflow
Table 1: Interrupt Vectors
7.1 System Calls
The b.trap and b.sys instructions allow processor exceptions to be generated by software.
A system call exception will be generated when the b.sys instruction is executed. This exception can, for example, be
used to enable a task to switch the processor into supervisor mode when a real time operating system is in use. (See
Section 3 for further details.)
The b.trap instruction is commonly used for trapping errors and for debugging.
7.2 Processor Exceptions
7.2.1 Bus Error
A bus error exception is generated when software attempts to access a memory address that does not exist, or is not
populated with memory or peripheral registers.
7.2.2 Alignment
Alignment exceptions are generated when software attempts to access objects that are not aligned to natural word
boundaries. 16-bit objects must be stored on even byte boundaries, while 32-bit objects must be stored on quad byte
boundaries. For instance, attempting to read a 16-bit object from address 0xFFF1 will trigger an alignment exception
as will a read of a 32-bit object from 0xFFF1, 0xFFF2 or 0xFFF3. Examples of legal 32-bit object addresses are
0xFFF0, 0xFFF4, 0xFFF8 etc.
7.2.3 Illegal Instruction
If the CPU reads an unrecognised instruction from memory as part of its instruction fetch, it will cause an illegal
instruction exception.
7.2.4 Stack Overflow
When enabled, a stack overflow exception occurs if the stack pointer reaches a programmable location.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 25
7.3 Hardware Interrupts
Hardware interrupts generated from the transceiver, analogue or digital peripherals and DIO pins are individually
masked using the Programmable Interrupt Controller (PIC). Management of interrupts is provided in the Peripherals
API User Guide [4]. For details of the interrupts generated from each peripheral see the respective section in this
datasheet.
Interrupts can be used to wake the JN516x from sleep. The peripherals, baseband controller, security coprocessor
and PIC are powered down during sleep but the DIO interrupts and optionally the pulse counters, wake-up timers and
analogue comparator interrupts remain powered to bring the JN516x out of sleep.
Prioritised external interrupt handling (i.e., interrupts from hardware peripherals) is provided to enable an application
to control an events priority to provide for deterministic program execution.
The priority Interrupt controller provides 15 levels of prioritised interrupts. The priority level of all interrupts can be set,
with value 0 being used to indicate that the source can never produce an external interrupt, 1 for the lowest priority
source(s) and 15 for the highest priority source(s). Note that multiple interrupt sources can be assigned the same
priority level if desired.
If while processing an interrupt, a new event occurs at the same or lower priority level, a new external interrupt will
not be triggered. However, if a new higher priority event occurs, the external interrupt will again be asserted,
interrupting the current interrupt service routine.
Once the interrupt service routine is complete, lower priority events can be serviced. 26 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
8 Wireless Transceiver
The wireless transceiver comprises a 2.45GHz radio, modem, a baseband processor, a security coprocessor and
PHY controller. These blocks, with protocol software provided as a library, implement an IEEE802.15.4 standardsbased
wireless transceiver that transmits and receives data over the air in the unlicensed 2.4GHz band.

Figure 13: Radio Architecture
The radio comprises a low-IF receive path and a direct modulation transmit path, which converge at the TX/RX
switch. The switch connects to the external single ended matching network, which consists of two inductors and a
capacitor, this arrangement creates a 50Ω port and removes the need for a balun. A 50Ω single ended antenna can
be connected directly to this port.
The 32MHz crystal oscillator feeds a divider, which provides the frequency synthesiser with a reference frequency.
The synthesiser contains programmable feedback dividers, phase detector, charge pump and internal Voltage
Controlled Oscillator (VCO). The VCO has no external components, and includes calibration circuitry to compensate
for differences in internal component values due to process and temperature variations. The VCO is controlled by a
Phase Locked Loop (PLL) that has an internal loop filter. A programmable charge pump is also used to tune the loop
characteristic.
The receiver chain starts with the low noise amplifier/mixer combination whose outputs are passed to a low pass
filter, which provides the channel definition. The signal is then passed to a series of amplifier blocks forming a limiting
strip. The signal is converted to a digital signal before being passed to the Modem. The gain control for the RX path
is derived in the automatic gain control (AGC) block within the Modem, which samples the signal level at various
points down the RX chain. To improve the performance and reduce current consumption, automatic calibration is
applied to various blocks in the RX path.
In the transmit direction, the digital stream from the Modem is passed to a digital sigma-delta modulator which
controls the feedback dividers in the synthesiser, (dual point modulation). The VCO frequency now tracks the applied
modulation. The 2.4 GHz signal from the VCO is then passed to the RF Power Amplifier (PA), whose power control
can be selected from one of three settings. The output of the PA drives the antenna via the RX/TX switch© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 27
The JN516x radio when enabled is automatically calibrated for optimum performance. In operating environments with
a significant variation in temperature (e.g. greater than 20 deg C) due to diurnal or ambient temperature variation, it is
recommended to recalibrate the radio to maintain performance. Recalibration is only required on Routers and End
Devices that never sleep. End Devices that sleep when idle are automatically recalibrated when they wake. An
Application Note JN516x Temperature-dependent Operating Guidelines [2] describes this in detail and includes a
software API function which can be used to test the temperature using the on-chip temperature sensor and trigger a
recalibration if there has been a significant temperature change since the previous calibration.
8.1.1 Radio External Components
In order to realise the full performance of the radio it is essential that the reference PCB layout and BOM are carefully
followed. See Appendix B.4.
The radio is powered from a number of internal 1.8V regulators fed from the analogue supply VDD1, in order to
provide good noise isolation between the digital logic of the JN516x and the analogue blocks. These regulators are
also controlled by the baseband controller and protocol software to minimise power consumption. Decoupling for
internal regulators is required as described in Section 2.2.1.
For single ended antennas or connectors, a balun is not required, however a matching network is needed.
The RF matching network requires three external components and the IBIAS pin requires one external component as
shown in schematic in B.4.1. These components are critical and should be placed close to the JN516x pins and
analogue ground as defined in Table 12. Specifically, the output of the network comprising L2, C1 and L1 is
designed to present an accurate match to a 50 ohm resistive network as well as provide a DC path to the final output
stage or antenna. Users wishing to match to other active devices such as amplifiers should design their networks to
match to 50 ohms at the output of L1

8.1.2 Antenna Diversity
Support is provided for antenna diversity. Antenna diversity is a technique that maximises the performance of an
antenna system. It allows the radio to switch between two antennas that have very low correlation between their
received signals. Typically, this is achieved by spacing two antennae around 0.25 wavelengths apart or by using two
orthogonal polarisations. So, if a packet is transmitted and no acknowledgement is received, the radio system can
switch to the other antenna for the retry, with a different probability of success.28 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
Additionally antenna diversity can be enabled whilst in receive mode waiting for a packet. The JN516x measures the
received energy in the relevant radio channel every 40μs and the measured energy level is compared with a pre-set
energy threshold, which can be set by the application program. The JN516x device will automatically switch the
antennae if the measurement is below this threshold, except if waiting for an acknowledgement from a previous
transmission or if the process of receiving a packet, when it will wait until this has finished. Also, it will not switch if a
preamble symbol having a signal quality above a minimum specified threshold has not been detected in the last 40μs
Both modes can be used at once and use the same ADO and ADE outputs to control the switch.
The JN516x provides an output (ADO) on DIO12 that is asserted on odd numbered retries and optionally its
complement (ADE) on DIO13, that can be used to control an antenna switch; this enables antenna diversity to be
implemented easily (see Figure 15 and Figure 16).

Features provided to support network channel selection algorithms include Energy Detection (ED), Link Quality

The Modem provides a digital Receive Signal Strength Indication (RSSI) that facilitates the implementation of the
IEEE 802.15.4 ED function and LQI function.
The ED and LQI are both related to receiver power in the same way, as shown in Figure 18. LQI is associated with a
received packet, whereas ED is an indication of signal power on air at a particular moment.
The CCA capability of the Modem supports all modes of operation defined in the IEEE 802.15.4 standard, namely
Energy above ED threshold, Carrier Sense and Carrier Sense and/or energy above ED threshold.

8.3 Baseband Processor
The baseband processor provides all time-critical functions of the IEEE802.15.4 MAC layer. Dedicated hardware
guarantees air interface timing is precise. The MAC layer hardware/software partitioning, enables software to
implement the sequencing of events required by the protocol and to schedule timed events with millisecond
resolution, and the hardware to implement specific events with microsecond timing resolution. The protocol software
layer performs the higher-layer aspects of the protocol, sending management and data messages between endpoint
and coordinator nodes, using the services provided by the baseband processor.

8.3.1 Transmit
A transmission is performed by software writing the data to be transferred into the Tx Frame Buffer in RAM, together
with parameters such as the destination address and the number of retries allowed, and programming one of the
protocol timers to indicate the time at which the frame is to be sent. This time will be determined by the software
tracking the higher-layer aspects of the protocol such as superframe timing and slot boundaries. Once the packet is
prepared and protocol timer set, the supervisor block controls the transmission. When the scheduled time arrives,
the supervisor controls the sequencing of the radio and modem to perform the type of transmission required, fetching
the packet data directly from RAM. It can perform all the algorithms required by IEEE802.15.4 such as CSMA/CA
without processor intervention including retries and random backoffs.
When the transmission begins, the header of the frame is constructed from the parameters programmed by the
software and sent with the frame data through the serialiser to the Modem. At the same time, the radio is prepared
for transmission. During the passage of the bitstream to the modem, it passes through a CRC checksum generator
that calculates the checksum on-the-fly, and appends it to the end of the frame.
8.3.2 Reception
During reception, the radio is set to receive on a particular channel. On receipt of data from the modem, the frame is
directed into the Rx Frame Buffer in RAM where both header and frame data can be read by the protocol software.
An interrupt may be provided on receipt of the frame header. As the frame data is being received from the modem it
is passed through a checksum generator; at the end of the reception the checksum result is compared with the
checksum at the end of the message to ensure that the data has been received correctly. An interrupt may be
provided to indicate successful packet reception. During reception, the modem determines the Link Quality, which is
made available at the end of the reception as part of the requirements of IEEE802.15.4.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 31
8.3.3 Auto Acknowledge
Part of the protocol allows for transmitted frames to be acknowledged by the destination sending an acknowledge
packet within a very short window after the transmitted frame has been received. The JN516x baseband processor
can automatically construct and send the acknowledgement packet without processor intervention and hence avoid
the protocol software being involved in time-critical processing within the acknowledge sequence. The JN516x
baseband processor can also request an acknowledge for packets being transmitted and handle the reception of
acknowledged packets without processor intervention.
8.3.4 Beacon Generation
In beaconing networks, the baseband processor can automatically generate and send beacon frames; the repetition
rate of the beacons is programmed by the CPU, and the baseband then constructs the beacon contents from data
delivered by the CPU. The baseband processor schedules the beacons and transmits them without CPU
intervention.
8.3.5 Security
The transmission and reception of secured frames using the Advanced Encryption Standard (AES) algorithm is
handled by the security coprocessor and the stack software. The application software must provide the appropriate
encrypt/decrypt keys for the transmission or reception. On transmission, the key can be programmed at the same
time as the rest of the frame data and setup information.
8.4 Security Coprocessor
The security coprocessor is available to the application software to perform encryption/decryption operations. A
hardware implementation of the encryption engine significantly speeds up the processing of the encrypted packets
over a pure software implementation. The AES library for the JN516x provides operations that utilise the encryption
engine in the device and allow the contents of memory buffers to be transformed. Information such as the type of
security operation to be performed and the encrypt/decrypt key to be used must also be provided.

8.5 Time of Flight Engine
The JN516x family includes unique hardware functions to enable measurement of the distance between two nodes
using a “Time of Flight” (ToF) function. This function uses dedicated timers and interpolation of the timing of
correlation peaks in the demodulator to measure the delays introduced by the time taken for the radio signals to travel
between nodes. It is also possible to use the received signal strength (RSSI) to indicate the distance. Due to the
characteristics of the transmitted signal and the baseband circuitry, ToF offers a significant improvement in accuracy
for distance measurements above 10m compared with RSSI, while RSSI provides better ranging results below 10m.
Hence, ToF is best suited to long range distance measurement. The raw timing results are made available through
an API function, but the responsibility for converting these into location information lies with the user.
For more information, see the Time-of-flight API User Guide [10]32 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
9 Digital Input/Output
There are 20 Digital I/O (DIO) pins which when used as general-purpose pins can be configured as either an input or
an output, with each having a selectable internal pull-up resistor. In addition, there are 2 Digital Output (DO) pins.
Most DIO pins are shared with the digital and analogue peripherals of the device. When a peripheral is enabled, it
takes control over the device pins allocated to it. However, note that most peripherals have 2 alternative pin
allocations to alleviate clashes between uses, and many peripherals can disable the use of specific pins if not
required. Refer to Section 2.1 and the individual peripheral descriptions for full details of the available pinout
arrangements.
Following a reset (and whilst the RESETN input is held low), all peripherals are forced off and the DIO pins are
configured as inputs with the internal pull-ups turned on.When a peripheral is not enabled, the DIO pins associated
with it can be used as digital inputs or outputs. Each pin can be controlled individually by setting the direction and
then reading or writing to the pin.
The individual pull-up resistors, RPU, can also be enabled or disabled as needed and the setting is held through sleep
cycles. The pull-ups are generally configured once after reset depending on the external components and
functionality. For instance, outputs should generally have the pull-ups disabled. An input that is always driven should
also have the pull-up disabled.
When configured as an input each pin can be used to generate an interrupt upon a change of state (selectable
transition either from low to high or high to low); the interrupt can be enabled or disabled. When the device is
sleeping, these interrupts become events that can be used to wake the device up. Equally the status of the interrupt
may be read. See Section 18 for further details on sleep and wakeup.
The state of all DIO pins can be read, irrespective of whether the DIO is configured as an input or an output.
Throughout a sleep cycle the direction of the DIO, and the state of the outputs, is held. This is based on the resultant
of the GPIO Data/Direction registers and the effect of any enabled peripherals at the point of entering sleep.
Following a wake-up these directions and output values are maintained under control of the GPIO data/direction
registers. Any peripherals enabled before the sleep cycle are not automatically re-enabled, this must be done through
software after the wake-up.
For example, if DIO0 is configured to be SPISEL1 then it becomes an output. The output value is controlled by the
SPI functional block. If the device then enters a sleep cycle, the DIO will remain an output and hold the value being
output when entering sleep. After wake-up the DIO will still be an output with the same value but controlled from the
GPIO Data/Direction registers. It can be altered with the software functions that adjust the DIO, or the application may
re-configure it to be SPISEL1.
Unused DIO pins are recommended to be set as inputs with the pull-up enabled.
Two DIO pins can optionally be used to provide control signals for RF circuitry (e.g. switches and PA) in high power
range extenders.
DIO3/RFTX is asserted when the radio is in the transmit state and similarly, DIO2/RFRX is asserted when the radio is
in the receiver state.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 33

10.1 Serial Peripheral Interface Master
The Serial Peripheral Interface (SPI) allows high-speed synchronous data transfer between the JN516x and
peripheral devices. The JN516x operates as a master on the SPI bus and all other devices connected to the SPI are
expected to be slave devices under the control of the JN516x CPU. The SPI includes the following features:
• Full-duplex, three-wire synchronous data transfer
• Programmable bit rates (up to 16Mbit/s)
• Programmable transaction size up to 32-bits
• Standard SPI modes 0,1,2 and 3
• Manual or Automatic slave select generation (up to 3 slaves)
• Maskable transaction complete interrupt

The SPI bus employs a simple shift register data transfer scheme. Data is clocked out of and into the active devices
in a first-in, first-out fashion allowing SPI devices to transmit and receive data simultaneously. Master-Out-Slave-In or
Master-In-Slave-Out data transfer is relative to the clock signal SPICLK generated by the JN516x.
The JN516x provides three slave selects, SPISEL0 to SPISEL2 to allow three SPI peripherals on the bus. SPISEL0
is accessed on DI019. SPISEL1 is accessed, depending upon the configuration, on DIO0 or DIO14. SPISEL2 is
accessed on DIO1 or DIO15. This is enabled under software control. The following table details which DIO are used

between transfers when required, to enable longer transfers to be performed.
When the device reset is active, all the SPI Master pins are configured as inputs with their pull-up resistors active.

Figure 23: Typical JN516x SPI Peripheral Connection
The data transfer rate on the SPI bus is determined by the SPICLK signal. The JN516x supports transfers at
selectable data rates from 16MHz to 125kHz selected by a clock divider. Both SPICLK clock phase and polarity are
configurable. The clock phase determines which edge of SPICLK is used by the JN516x to present new data on the
SPIMOSI line; the opposite edge will be used to read data from the SPIMISO line. The interface should be configured
appropriately for the SPI slave being accessed.

Table 3: SPI Configurations36 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
If more than one SPISEL line is to be used in a system they must be used in numerical order starting from SPISEL0.
A SPISEL line can be automatically de-asserted between transactions if required, or it may stay asserted over a
number of transactions. For devices such as memories where a large amount of data can be received by the master
by continually providing SPICLK transitions, the ability for the select line to stay asserted is an advantage since it
keeps the slave enabled over the whole of the transfer.
A transaction commences with the SPI bus being set to the correct configuration, and then the slave device is
selected. Upon commencement of transmission (1 to 32 bits) data is placed in the FIFO data buffer and clocked out,
at the same time generating the corresponding SPICLK transitions. Since the transfer is full-duplex, the same
number of data bits is being received from the slave as it transmits. The data that is received during this transmission
can be read (1 to 32 bits). If the master simply needs to provide a number of SPICLK transitions to allow data to be
sent from a slave, it should perform transmit using dummy data. An interrupt can be generated when the transaction
has completed or alternatively the interface can be polled.
If a slave device wishes to signal the JN516x indicating that it has data to provide, it may be connected to one of the
DIO pins that can be enabled as an interrupt.
Figure 24 shows a complex SPI transfer, reading data from a FLASH device that can be achieved using the SPI
master interface. The slave select line must stay low for many separate SPI accesses, and therefore manual slave
select mode must be used. The required slave select can then be asserted (active low) at the start of the transfer. A
sequence 8 and 32 bit transfers can be used to issue the command and address to the FLASH device and then to
read data back. Finally, the slave select can be deselected to end the transaction.

The Serial Peripheral Interface (SPI) Slave Interface allows high-speed synchronous data transfer between the
JN516x and a peripheral device. The JN516x operates as a slave on the SPI bus and an external device connected
to the SPI bus operates as the master. The pins are different from the SPI master interface and are shown in the

Table 4: SPI Slave IO
The SPI bus employs a simple shift register data transfer scheme, with SPISSEL acting as the active low select
control. Data is clocked out of and into the active devices in a first-in, first-out fashion allowing SPI devices to
transmit and receive data simultaneously. Master-Out-Slave-In or Master-In-Slave-Out data transfer is relative to the
clock signal SPISCLK generated by the external master.
The SPI slave includes the following features:
• Full-duplex synchronous data transfer
• Slaves to external clock up to 8MHz
• Supports 8 bit transfers (MSB or LSB first configurable), with SPISSEL deselected between each transfer
• Internal FIFO up to 255 bytes for transmit and receive
• Standard SPI mode 0, data is sampled on positive clock edge
• Maskable interrupts for receive FIFO not empty, transmit FIFO empty, receive FIFO fill level above
threshold, transmit FIFO fill level below threshold, transmit FIFO overflow, receive FIFO overflow, receive
FIFO underflow, transmit FIFO underflow, receive timeout
• Programmable receive timeout period allows an interrupt to be generated to prompt the receive FIFO to
be read if no further data arrives within the timeout period38 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
11 Timers
11.1 Peripheral Timer/Counters
A general-purpose timer/counter unit, Timer0, is available that can be configured to operate in one of five possible
modes. This has:
• Clocked from internal system clock (16MHz)
• 5-bit prescaler, divides system clock by 2 prescale value as the clock to the timer (prescaler range is 0 to 16)
• 16-bit counter, 16-bit Rise and Fall (period) registers
• Timer: can generate interrupts off Rise and Fall counts. Can be gated by external signal
• Counter: counts number of transitions on external event signal. Can use low-high, high-low or both
transitions
• PWM/Single pulse: outputs repeating Pulse Width Modulation signal or a single pulse. Can set period and
mark-space ratio
• Capture: measures times between transitions of an applied signal
• Delta-Sigma: Return-To-Zero (RTZ) and Non-Return-to-Zero (NRZ) modes
• Timer usage of external IO can be controlled on a pin by pin basis
Four further timers are also available that support the same functionality but have no Counter or Capture mode.
These are referred to as PWM timers. Additionally, is not possible to gate these four timers with an external signal.

The clock source for the Timer0 unit is fed from the 16MHz system clock. This clock passes to a 5-bit prescaler
where a value of 0 leaves the clock unmodified and other values divide it by 2 prescale value. For example, a prescale
value of 2 applied to the 16MHz system clock source results in a timer clock of 4MHz.
The counter is optionally gated by a signal on the clock/gate input (TIM0CK_GT). If the gate function is selected,
then the counter is frozen when the clock/gate input is high.
An interrupt can be generated whenever the counter is equal to the value in either of the High or Low registers.

The alternative pin locations can be configured separately for each counter/timer under software control, without
affecting the operation or location of the others If operating in timer mode, it is not necessary to use any of the DIO
pins, allowing the standard DIO functionality to be available to the application.
11.1.1 Pulse Width Modulation Mode
Pulse Width Modulation (PWM) mode, as used by PWM timers 1,2 3 and 4 and optionally by Timer0, allows the user
to specify an overall cycle time and pulse length within the cycle. The pulse can be generated either as a single shot
or as a train of pulses with a repetition rate determined by the cycle time.
In this mode, the cycle time and low periods of the PWM output signal can be set by the values of two independent
16-bit registers (Fall and Rise). The counter increments and its output is compared to the 16-bit Rise and Fall
registers. When the counter is equal to the Rise register, the PWM output is set to high; when the counter reaches
the Fall value, the output returns to low. In continuous mode, when the counter reaches the Fall value, it will reset
and the cycle repeats. If either the cycle time or low periods are changed while in continuous mode, the new values
are not used until a full cycle has completed. The PWM waveform is available on PWM1,2,3,4 or TIM0OUT when the
output driver is enabled.

Fall
Figure 26 PWM Output Timings
11.1.2 Capture Mode
The capture mode can be used to measure the time between transitions of a signal applied to the capture input
(TIM0CAP). When the capture is started, on the next low-to-high transition of the captured signal, the count value is
stored in the Rise register, and on the following high-to-low transition, the counter value is stored in the Fall register.
The pulse width is the difference in counts in the two registers multiplied by the period of the prescaled clock. Upon
reading the capture registers the counter is stopped. The values in the High and Low registers will be updated
whenever there is a corresponding transition on the capture input, and the value stored will be relative to when the
mode was started. Therefore, if multiple pulses are seen on TIM0CAP before the counter is stopped only the last
pulse width will be stored. 40 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

The counter/timer can be used to generate interrupts, based on the timers or event counting, for software to use. As
a timer the clock source is from the system clock, prescaled if required. The timer period is programmed into the fall
register and the Fall register match interrupt enabled. The timer is started as either a single-shot or a repeating timer,
and generates an interrupt when the counter reaches the Fall register value.
When used to count external events on TIM0CK_GT the clock source is selected from the input pin and the number
of events programmed into the Fall register. The Fall register match interrupt is enabled and the counter started,
usually in single shot mode. An interrupt is generated when the programmed number of transitions is seen on the
input pin. The transitions counted can configured to be rising, falling or both rising and falling edges.
Edges on the event signal must be at least 100nsec apart, i.e. pulses must be wider than 100nsec.
11.1.4 Delta-Sigma Mode
A separate delta-sigma mode is available, allowing a low speed delta-sigma DAC to be implemented with up to 16-bit
resolution. This requires that a resistor-capacitor network is placed between the output DIO pin and digital ground. A
stream of pulses with digital voltage levels is generated which is integrated by the RC network to give an analogue
voltage. A conversion time is defined in terms of a number of clock cycles. The width of the pulses generated is the
period of a clock cycle. The number of pulses output in the cycle, together with the integrator RC values, will
determine the resulting analogue voltage. For example, generating approximately half the number of pulses that
make up a complete conversion period will produce a voltage on the RC output of VDD1/2, provided the RC time
constant is chosen correctly. During a conversion, the pulses will be pseudo-randomly dispersed throughout the
cycle in order to produce a steady voltage on the output of the RC network.
The output signal is asserted for the number of clock periods defined in the High register, with the total period being
216 cycles. For the same value in the High register, the pattern of pulses on subsequent cycles is different, due to the
pseudo-random distribution.
The delta-sigma converter output can operate in a Return-To-Zero (RTZ) or a Non-Return-to-Zero (NRZ) mode. The
NRZ mode will allow several pulses to be output next to each other. The RTZ mode ensures that each pulse is
separated from the next by at least one period. This improves linearity if the rise and fall times of the output are
different to one another. Essentially, the output signal is low on every other output clock period, and the conversion
cycle time is twice the NRZ cycle time i.e. 217 clocks. The integrated output will only reach half VDD2 in RTZ mode,
since even at full scale only half the cycle contains pulses. Figure 28 and Figure 29 illustrate the difference between
RTZ and NRZ for the same programmed number of pulses.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 41

11.1.5 Infra-Red Transmission Mode
Infra-red transmission mode is a special feature of Timer 2 that is used to facilitate the generation of waveforms for
infra-red remote control transmission. Remote control protocols, such as Philips RC-6, apply On-Off Key (OOK)
modulation to a carrier signal using an encoded bit stream. The infra-red transmission mode supports a variety of
remote control protocols that have different carrier frequency, carrier duty-cycle and data bit encoding requirements.
In this mode, Timer 2 is configured to produce a carrier waveform that is OOK modulated by a programmable bit
sequence of up to 4096 bits stored in RAM. The resultant waveform is output to the associated Timer 2 output pin.
The JN516x Integrated Peripherals API User Guide [4] includes some examples.
11.1.6 Example Timer/Counter Application
Figure 30 shows an application of the JN516x timers to provide closed loop speed control. PWM1 is configured in
PWM mode to provide a variable mark-space ratio switching waveform to the gate of the NFET. This in turn controls
the power in the DC motor.
Timer 0 is configured to count the rising edge events on the clk/gate pin over a constant period. This converts the
tacho pulse stream output into a count proportional to the motor speed. This value is then used by the application
software executing the control algorithm.
If required for other functionality, then the unused IO associated with the timers could be used as general purpose
DIO.

11.2 Tick Timer
The JN516x contains a hardware timer that can be used for generating timing interrupts to software. It may be used
to implement regular events such as ticks for software timers or an operating system, as a high-precision timing
reference or can be used to implement system monitor timeouts as used in a watchdog timer. Features include:
• 32-bit counter
• 28-bit match value
• Maskable timer interrupt
• Single-shot, Restartable or Continuous modes of operation

Figure 31 Tick Timer
The Tick Timer is clocked from a continuous 16MHz clock, which is fed to a 32-bit wide resettable up-counter, gated
by a signal from the mode control block. A match register allows comparison between the counter and a
programmed value. The match value, measured in 16MHz clock cycles is programmed through software, in the
range 0 to 0x0FFFFFFF. The output of the comparison can be used to generate an interrupt if the interrupt is
enabled and used in controlling the counter in the different modes. Upon configuring the timer mode, the counter is
also reset.
If the mode is programmed as single shot, the counter begins to count from zero until the match value is reached.
The match signal will be generated which will cause an interrupt if enabled, and the counter will stop counting. The
counter is restarted by reprogramming the mode.
If the mode is programmed as restartable, the operation of the counter is the same as for the single shot mode,
except that when the match value is reached the counter is reset and begins counting from zero. An interrupt will be
generated when the match value is reached if it is enabled.
Continuous mode operation is similar to restartable, except that when the match value is reached, the counter is not
reset but continues to count. An interrupt will be generated when the match value is reached if enabled.
11.3 Wakeup Timers
Two -41 bit wakeup timers are available in the JN516x driven from the 32kHz internal clock. They may run during
sleep periods when the majority of the rest of the device is powered down, to time sleep periods or other long period
timings that may be required by the application. The wakeup timers do not run during deep sleep and may optionally © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 43
be disabled in sleep mode through software control. When a wakeup timer expires it typically generates an interrupt,
if the device is asleep then the interrupt may be used as an event to end the sleep period. See Section 18 for further
details on how they are used during sleep periods. Features include:
• 41-bit down-counter
• Optionally runs during sleep periods
• Clocked by 32kHz system clock; either 32kHz RC oscillator, 32kHz XTAL oscillator or 32kHz clock input
A wakeup timer consists of a 41-bit down counter clocked from the selected 32 kHz clock. An interrupt or wakeup
event can be generated when the counter reaches zero. On reaching zero the counter will continue to count down
until stopped, which allows the latency in responding to the interrupt to be measured. If an interrupt or wakeup event
is required, the timer interrupt should be enabled before loading the count value for the period. Once the count value
is loaded and counter started, the counter begins to count down; the counter can be stopped at any time through
software control. The counter will remain at the value it contained when the timer was stopped and no interrupt will
be generated. The status of the timers can be read to indicate if the timers are running and/or have expired; this is
useful when the timer interrupts are masked. This operation will reset any expired status flags.
11.3.1 32 KHZ RC Oscillator Calibration
The 32 KHZ RC oscillator that can be used to time sleep periods is designed to require very little power to operate
and be self-contained, requiring no external timing components and hence is lower cost. As a consequence of using
on-chip resistors and capacitors, the inherent absolute accuracy and temperature coefficient is lower than that of a
crystal oscillator, but once calibrated the accuracy approaches that of a crystal oscillator. Sleep time periods should
be as close to the desired time as possible in order to allow the device to wake up in time for important events, for
example beacon transmissions in the IEEE802.15.4 protocol. If the sleep time is accurate, the device can be
programmed to wake up very close to the calculated time of the event and so keep current consumption to a
minimum. If the sleep time is less accurate, it will be necessary to wake up earlier in order to be certain the event will
be captured. If the device wakes earlier, it will be awake for longer and so reduce battery life. Please note, that
oscillator has a default current consumption of around 0.5uA, optionally this can be reduced to 0.375uA, which can
improve battery life, however, the calibrated accuracy and temperature coefficient will be worse as a consequence.
For detailed electrical specifications, see Section 19.3.9.
In order to allow sleep time periods to be as close to the desired length as possible, the true frequency of the RC
oscillator needs to be determined to better than the initial 30% accuracy. The calibration factor can then be used to
calculate the true number of nominal 32kHz periods needed to make up a particular sleep time. A calibration
reference counter, clocked from the 16MHz system clock, is provided to allow comparisons to be made between the
32kHz RC clock and the 16MHz system clock when the JN516x is awake and running from the 32MHZ crystal.
Wakeup timer0 counts for a set number of 32kHz clock periods during which time the reference counter runs. When
the wakeup timer reaches zero the reference counter is stopped, allowing software to read the number of 16MHz
clock ticks generated during the time represented by the number of 32kHz ticks programmed in the wakeup timer.
The true period of the 32kHz clock can thus be determined and used when programming a wakeup timer to achieve a
better accuracy and hence more accurate sleep periods
For a RC oscillator running at exactly 32,000Hz the value returned by the calibration procedure should be 10000, for
a calibration period of twenty 32,000Hz clock periods. If the oscillator is running faster than 32,000Hz the count will
be less than 10000, if running slower the value will be higher. For a calibration count of 9000, indicating that the RC
oscillator period is running at approximately 35kHz, to time for a period of 2 seconds the timer should be loaded with
71,111 ((10000/9000) x (32000 x 2)) rather than 64000.44 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
12 Pulse Counters
Two 16-bit counters are provided that can increment during all modes of operation (including sleep). The first, PC0,
increments from pulses received on DIO1 or DIO4. The other pulse counter, PC1 operates from DIO5 or DIO8
depending upon the configuration. This is enabled under software control. The pulses can be de-bounced using the
32kHz clock to guard against false counting on slow or noisy edges. Increments occur from a configurable rising or
falling edge on the respective DIO input.
Each counter has an associated 16-bit reference that is loaded by the user. An interrupt (and wakeup event if
asleep) may be generated when a counter reaches its pre-configured reference value. The two counters may
optionally be cascaded together to provide a single 32-bit counter, linked to any of the four DIO’s. The counters do
not saturate at 65535, but naturally roll-over to 0. Additionally, the pulse counting continues when the reference value
is reached without software interaction so that pulses are not missed even if there is a long delay before an interrupt
is serviced or during the wakeup process.
The system can work with signals up to 100kHz, with no debounce, or from 5.3kHz to 1.7kHz with debounce. When
using debounce the 32kHz clock must be active, so for minimum sleep currents the debounce mode should not be
used.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 45
13 Serial Communications
The JN516x has two Universal Asynchronous Receiver/Transmitter (UART) serial communication interfaces. These
provide similar operating features to the industry standard 16550A device operating in FIFO mode. The interfaces
perform serial-to-parallel conversion on incoming serial data and parallel-to-serial conversion on outgoing data from
the CPU to external devices. In both directions, a configurable FIFO buffer (with a default depth of 16-bytes) allows
the CPU to read and write multiple characters on each transaction. This means that the CPU is freed from handling
data on a character-by-character basis, with the associated high processor overhead. The UARTs have the following
features:
• Emulates behaviour of industry standard NS16450 and NS16550A UARTs
• Configurable transmit and receive FIFO buffers (with default depths of 16-bytes for each), with direct access
to fill levels of each. Adds/deletes standard start, stop and parity bits to or from the serial data
• Independently controlled transmit, receive, status and data sent interrupts
• Optional modem flow control signals CTS and RTS on UART0.
• Fully programmable data formats: baud rate, start, stop and parity settings
• False start bit detection, parity, framing and FIFO overrun error detect and break indication
• Internal diagnostic capabilities: loop-back controls for communications link fault isolation
• Flow control by software or automatically by hardware Processor Bus

Figure 32: UART Block Diagram
The serial interfaces contain programmable fields that can be used to set number of data bits (5, 6,7 or 8), even, odd,
set-at-1, set-at-0 or no-parity detection and generation of single or multiple stop bit, (for 5 bit data, multiple is 1.5 stop
bits; for 6, 7 or 8 data bits, multiple is 2 bits).
The baud rate is programmable up to 1Mbps, standard baud rates such as 4800, 9600, 19.2k, 38.4k etc. can be
configured.
For applications requiring hardware flow control, UART0 provides two control signals: Clear-To-Send (CTS) and
Request-To-Send (RTS). CTS is an indication sent by an external device to the UART that it is ready to receive data.
RTS is an indication sent by the UART to the external device that it is ready to receive data. RTS is controlled from
software, while the value of CTS can be read. Monitoring and control of CTS and RTS is a software activity, normally
performed as part of interrupt processing. The signals do not control parts of the UART hardware, but simply indicate
to software the state of the UART external interfaces. Alternatively, the Automatic Flow Control mode can be set 46 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
where the hardware controls the value of the generated RTS (negated if the receive FIFO fill level is greater than a
programmable threshold of 8, 11, 13 or 15 bytes), and only transmits data when the incoming CTS is asserted.
Software can read characters, one byte at a time, from the Receive FIFO and can also write to the Transmit FIFO,
one byte at a time. The Transmit and Receive FIFOs can be cleared and reset independently of each other. The
status of the Transmit FIFO can be checked to see if it is empty, and if there is a character being transmitted. The
status of the Receive FIFO can also be checked, indicating if conditions such as parity error, framing error or break
indication have occurred. It also shows if an overrun error occurred (receive buffer full and another character arrives)
and if there is data held in the receive FIFO.
UART0 and UART1 can both be configured to use standard or alternative DIO lines, as shown in Table 5.
Additionally, UART0 can be configured to be used in 2-wire mode (where CTS0 and RTS0 are not configured), and
UART1 can be configured in 1-wire mode (where RXD1 is not configured). These freed up DIO pins can then be used
for other purposes.

.
Note: With the automatic flow control threshold set to 15, the hardware flow control within the UART’s block negates
RTS when they receive FIFO that is about to become full. In some instances it has been observed that remote
devices that are transmitting data do not respond quickly enough to the de-asserted CTS and continue to transmit
data. In these instances the data will be lost in a receive FIFO overflow.
13.1 Interrupts
Interrupt generation can be controlled for the UART’s block, and is divided into four categories:
• Received Data Available: Is set when data in the Rx FIFO queue reaches a particular level (the trigger level can
be configured as 1, 4, 8 or 14) or if no character has been received for 4 character times.
• Transmit FIFO Empty: set when the last character from the Tx FIFO is read and starts to be transmitted.
• Receiver Line Status: set when one of the following occur (1) Parity Error - the character at the head of the
receive FIFO has been received with a parity error, (2) Overrun Error - the Rx FIFO is full and another character
has been received at the Receiver shift register, (3) Framing Error - the character at the head of the receive
FIFO does not have a valid stop bit and (4) Break Interrupt – occurs when the RxD line has been held low for an
entire character.
• Modem Status: Generated when the CTS (Clear To Send) input control line changes.

C)
The JN516x includes industry standard I
2
C two-wire synchronous Serial Interface operates as a Master (MSIF) or
Slave (SSIF) that provides a simple and efficient method of data exchange between devices. The system uses a
serial data line (SIF_D) and a serial clock line (SIF_CLK) to perform bi-directional data transfers and includes the
following features:
Common to both master and slave:
• Compatible with both I2
C and SMbus peripherals
• Support for 7 and 10-bit addressing modes
• Optional pulse suppression on signal inputs (60ns guaranteed, 125ns typical)
Master only:
• Multi-master operation
• Software programmable clock frequency
• Supports Slave clock stretching
• Software programmable acknowledge bit
• Interrupt or bit-polling driven byte-by-byte data-transfers
• Bus busy detection
Slave only:
• Programmable slave address
• Simple byte level transfer protocol
• Write data flow control using acknowledge mechanism
• Read data flow control using clock stretching
• Read data preloaded or provided as required
The Serial Interface is accessed, depending upon the configuration, DIO14 and DIO15 or DIO16 and DIO17. This is
enabled under software control. The following table details which DIO are used for the Serial Interface depending

15.1 Connecting Devices
The clock and data lines, SIF_D and SIF_CLK, are alternate functions of DIO15 and DIO14 respectively. The serial
interface function of these pins is selected when the interface is enabled. They are both bi-directional lines,
connected internally to the positive supply voltage via weak (50kΩ) programmable pull-up resistors. However, it is
recommended that external 4.7kΩ pull-ups be used for reliable operation at high bus speeds, as shown in Figure 34.
When the bus is free, both lines are HIGH. The output stages of devices connected to the bus must have an opendrain
or open-collector in order to perform the wired-AND function. The number of devices connected to the bus is
solely dependent on the bus capacitance limit of 400pF.
As this is an optional interface with two alternate positions, the DIO cells have not been customised for I
2
C operation.
In particular, note that there are ESD diodes to the nominal 3 volt supply (VDD2) from the SIF_CLK and SIF_D pins.
Therefore, if the VDD supply is removed from the JN5168 and this then discharges to ground, a path would exist that
could pull down the bus lines (see 2.2.6).50 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

15.2 Clock Stretching
Slave devices can use clock stretching to slow down the read transfer bit rate. After the master has driven SIF_CLK
low, the slave can drive SIF_CLK low for the required period and then release it. If the slave’s SIF_CLK low period is
greater than the master’s low period the resulting SIF_CLK bus signal low period is stretched thus inserting wait
states – see section 15.4 for further details.

15.3 Master Two-wire Serial Interface
When operating as a master device, it provides the clock signal and a prescale register determines the clock rate,
allowing operation up to 400kbit/s.
Data transfer is controlled from the processor bus interface at a byte level, with the processor responsible for
indicating when start, stop, read, write and acknowledge control should be generated. Write data written into a
transmit buffer will be written out across the two-wire interface when indicated, and read data received on the
interface is made available in a receive buffer. Indication of when a particular transfer has completed may be
indicated by means of an interrupt or by polling a status bit.
The first byte of data transferred by the device after a start bit is the slave address. The JN516x supports both 7-bit
and 10-bit slave addresses by generating either one or two address transfers. Only the slave with a matching address
will respond by returning an acknowledge bit.
The master interface provides a true multi-master bus including collision detection and arbitration that prevents data
corruption. If two or more masters simultaneously try to control the bus, a clock synchronization procedure
determines the bus clock. Because of the wired-AND connection of the interface, a high-to-low transition on the bus
affects all connected devices. This means a high-to-low transition on the SIF_CLK line causes all concerned devices
to count off their low period. Once the clock input of a device has gone low, it will hold the SIF_CLK line in that state
until the clock high state is reached when it releases the SIF_CLK line. Due to the wired-AND connection, the
SIF_CLK line will therefore be held low by the device with the longest low period, and held high by the device with the
shortest high period.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 51

After each transfer has completed, the status of the device must be checked to ensure that the data has been
acknowledged correctly, and that there has been no loss of arbitration. (N.B. Loss of arbitration may occur at any
point during the transfer, including data cycles). An interrupt will be generated when arbitration has been lost.52 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
15.4 Slave Two-wire Serial Interface
When operating as a slave device, the interface does not provide a clock signal, although it may drive the clock signal
low if it is required to apply clock stretching during read transfers.
Only transfers whose address matches the value programmed into the interface’s address register are accepted. The
interface allows both 7 and 10 bit addresses to be programmed, but only responds with an acknowledge to a single
address. Addresses defined as “reserved” will not be responded to, and should not be programmed into the address
register. A list of reserved addresses is shown in Table 8.

1111 1XX Reserved Ignored
1111 0XX 10-bit address Only responded to if 10 bit address
set in address register
Table 8 : List of two-wire serial interface reserved addresses
Data transfer is controlled from the processor bus interface at a byte level, with the processor responsible for taking
write data from a receive buffer and providing read data to a transmit buffer when indicated. A series of interrupt
status bits are provided to control the flow of data.
For writes, in to the slave interface, it is important that data is taken from the receive buffer by the processor before
the next byte of data arrives. To enable this, the interface returns a Not Acknowledge (NACK) to the master if more
data is received before the previous data has been taken. This will lead to the termination of the current data transfer.
For reads, from the slave interface, the data may be preloaded into the transmit buffer when it is empty (i.e. at the
start of day, or when the last data has been read), or fetched each time a read transfer is requested. When using data
preload, read data in the buffer must be replenished following a data write, as the transmit and received data is
contained in a shared buffer. The interface will hold the bus using clock stretching when the transmit buffer is empty.
Interrupts may be triggered when:
• Data Buffer read data is required – a byte of data to be read should be provided to avoid the interface from
clock stretching
• Data Buffer read data has been taken – this indicates when the next data may be preloaded into the data
buffer
• Data Buffer write data is available – a byte of data should be taken from the data buffer to avoid data backoff
as defined above
• The last data in a transfer has completed – i.e. the end of a burst of data, when a Stop or Restart is seen
• A protocol error has been spotted on the interface© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 53
16 Random Number Generator
A random number generator is provided which creates a 16-bit random number each time it is invoked. Consecutive
calls can be made to build up any length of random number required. Each call takes approximately 0.25msec to
complete. Alternatively, continuous generation mode can be used where a new number is generated approximately
every 0.25msec. In either mode of operation an interrupt can be generated to indicate when the number is available,
or a status bit can be polled.
The random bits are generated by sampling the state of the 32MHz clock every 32kHz system clock edge. As these
clocks are asynchronous to each other, each sampled bit is unpredictable and hence random.54 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

In order to provide good isolation from digital noise, the analogue peripherals and radio are powered by the radio
regulator, which is supplied from the analogue supply VDD1 and referenced to analogue ground VSSA.
A reference signal Vref for the ADC can be selected between an internal bandgap reference or an external voltage
reference supplied to the VREF pin. ADC input 2 cannot be used if an external reference is required, as this uses the
same pin as VREF. Note also that ADC3 and ADC4 use the same pins as DIO0 and DIO1 respectively. These pins
can only be used for the ADC if they are not required for any of their alternative functions. Similarly, the comparator
inputs are shared with DIO16 and DIO17. If used for their analogue functions, these DIOs must be put into a passive
state by setting them to Inputs with their pull-ups disabled.
The ADC is clocked from a common clock source derived from the 16MHz clock.
17.1 Analogue to Digital Converter
The 10-bit analogue to digital converter (ADC) uses a successive approximation design to perform high accuracy
conversions as typically required in wireless sensor network applications. It has six multiplexed single-ended input
channels: four available externally, one connected to an internal temperature sensor, and one connected to an
internal supply monitoring circuit.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 55
17.1.1 Operation
The input range of the ADC can be set between 0V to either the reference voltage or twice the reference voltage.
The reference can be either taken from the internal voltage reference or from the external voltage applied to the
VREF pin. For example, an external reference of 1.2V supplied to VREF may be used to set the ADC range between
0V and 2.4V.

Table 9: ADC Maximum Input Range
The input clock to the ADC is 16MHz and can be divided down to 2MHz, 1MHz, 500kHz and 250kHz. During an ADC
conversion the selected input channel is sampled for a fixed period and then held. This sampling period is defined as
a number of ADC clock periods and can be programmed to 2, 4, 6 or 8. The conversion rate is ((3 x Sample period)
+ 13) clock periods. For example for 500kHz conversion with sample period of 2 will be (3 x 2) + 13 = 19 clock
periods, 38µsecs or 26.32kHz. The ADC can be operated in either a single conversion mode or alternatively a new
conversion can be started as soon as the previous one has completed, to give continuous conversions.
If the source resistance of the input voltage is 1kΩ or less, then the default sampling time of 2 clocks should be used.
The input to the ADC can be modelled as a resistor of 5kΩ(typ) and 10kΩ (max) to represent the on-resistance of the
switches and the sampling capacitor 8pF. The sampling time required can then be calculated, by adding the sensor
source resistance to the switch resistance, multiplying by the capacitance giving a time constant. Assuming normal
exponential RC charging, the number of time constants required to give an acceptable error can be calculated, 7 time
constants gives an error of 0.091%, so for 10-bit accuracy 7 time constants should be the target. For a source with
zero resistance, 7 time constants is 640 nsecs, hence the smallest sampling window of 2 clock periods can be used.

Figure 38: ADC Input Equivalent Circuit
The ADC sampling period, input range and mode (single shot or continuous) are controlled through software.
When the ADC conversion is complete, an interrupt is generated. Alternatively the conversion status can be polled.
When operating in continuous mode, it is recommended that the interrupt is used to signal the end of a conversion,
since conversion times may range from 9.5 to 148 µsecs. Polling over this period would be wasteful of processor
bandwidth.
To facilitate averaging of the ADC values, which is a common practice in microcontrollers, a dedicated accumulator
has been added, the user can define the accumulation to occur over 2,4,8 or 16 samples. The end of conversion
interrupt can be modified to occur at the end of the chosen accumulation period, alternatively polling can still be used.
Software can then be used to apply the appropriate rounding and shifting to generate the average value, as well as
setting up the accumulation function.

17.1.2 Supply Monitor
The internal supply monitor allows the voltage on the analogue supply pin VDD1 to be measured. This is achieved
with a potential divider that reduces the voltage by a factor of 0.666, allowing it to fall inside the input range of the
ADC when set with an input range twice the internal voltage reference. The resistor chain that performs the voltage
reduction is disabled until the measurement is made to avoid a continuous drain on the supply.
17.1.3 Temperature Sensor
The on chip temperature sensor can be used either to provide an absolute measure of the device temperature or to
detect changes in the ambient temperature. In common with most on chip temperature sensors, it is not trimmed and
so the absolute accuracy variation is large; the user may wish to calibrate the sensor prior to use. The sensor forces
a constant current through a forward biased diode to provide a voltage output proportional to the chip die temperature
which can then be measured using the ADC. The measured voltage has a linear relationship to temperature as
described in Section 19.3.13.
Because this sensor is on chip, any measurements taken must account for the thermal time constants. For example,
if the device just came out of sleep mode the user application should wait until the temperature has stabilised before
taking a measurement.
17.1.4 ADC Sample Buffer Mode
In this mode, the ADC operates in conjunction with a DMA (Direct Memory Access) engine as follows:
• ADC sampling is triggered at a configurable rate using one of the on-chip Timers (Timer 0, 1, 2, 3 or 4)
• ADC samples are automatically stored in a buffer located in RAM using a DMA mechanism
• ADC inputs may be multiplexed between different analogue sources
The 10-bit ADC data samples are transferred into the buffer in RAM as 16-bit words. The maximum number of 16-bit
words that may allocated in RAM for ADC sample storage is 2047.
The buffer may be configured to automatically wrap around to the start when full. Interrupts may be configured to
indicate when the buffer is half-full, full and has overflowed.
The CPU may perform other tasks while the data transfer and storage is being managed independently by the DMA
engine - the CPU only needs to configure the ADC sample buffer mode and deal with the stored samples in the buffer
when an interrupt occurs.
ADC sample buffer mode allows up to six analogue inputs to be multiplexed in combination. These inputs comprise
four external inputs (ADC1-4, corresponding to IO pins), an on-chip temperature sensor and an internal voltage
monitor. Samples from all the selected inputs will be produced on each timer trigger and stored in consecutive RAM
locations.
17.2 Comparator
The JN516x contains one analogue comparator, COMP1, that is designed to have true rail-to-rail inputs and operate
over the full voltage range of the analogue supply VDD1. The hysteresis level can be set to a nominal value of 0mV,
10mV, 20mV or 40mV. The source of the negative input signal for the comparator can be set to the internal voltage
reference, the negative external pin (COMP1M, which uses the same pin as DIO17) or the positive external pin
(COMP1P, on the same pin as DIO16). The source of the positive input signal can be COMP1P or COMP1M.
DIO16 and DIO17 cannot be used if the external comparator inputs are needed. The comparator output is routed to
an internal register and can be polled, or can be used to generate interrupts. The comparator can be disabled to
reduce power consumption. DIO16 and DIO17 should be set to inputs with pull-ups disabled, when using the
comparator.
The comparator also has a low power mode where the response time of the comparator is slower than the normal
mode, but the current required is greatly reduced. These figures are specified in Section 19.3.8. It is the only mode
that may be used during sleep, where a transition of the comparator output will wake the device. The wakeup action
and the configuration for which edge of the comparator output will be active are controlled through software. In sleep
mode the negative input signal source must be configured to be driven from the external pins.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 57
18 Power Management and Sleep Modes
18.1 Operating Modes
Three operating modes are provided in the JN516x that enable the system power consumption to be controlled
carefully to maximise battery life.
• Active Processing Mode
• Sleep Mode
• Deep Sleep Mode
The variation in power consumption of the three modes is a result of having a series of power domains within the chip
that may be controllably powered on or off.
18.1.1 Power Domains
The JN516x has the following power domains:
• VDD Supply Domain: supplies the wake-up timers and controller, DIO blocks, Comparator, SVM and BOR plus
Fast RC, 32kHz RC and crystal oscillators. This domain is driven from the external supply (battery) and is
always powered. The wake-up timers and controller, and the 32kHz RC and crystal oscillators may be powered
on or off in sleep mode through software control.
• Digital Logic Domain: supplies the digital peripherals, CPU, Flash, RAM when in Active Processing Mode,
Baseband controller, Modem and Encryption processor. It is powered off during sleep mode.
• RAM Domain: supplies the RAM when in Active Processing Mode. Also supplies the Ram during sleep mode to
retain the memory contents. It may be powered on or off for sleep mode through software control.
• Radio Domain: supplies the radio interface, ADCs and temperature sensor. It is powered during transmit and
receive and when the analogue peripherals are enabled. It is controlled by the baseband processor and is
powered off during sleep mode.
The current consumption figures for the different modes of operation of the device is given in Section 19.2.2.
18.2 Active Processing Mode
Active processing mode in the JN516x is where all of the application processing takes place. By default, the CPU will
execute at the selected clock speed executing application firmware. All of the peripherals are available to the
application, as are options to actively enable or disable them to control power consumption; see specific peripheral
sections for details.
Whilst in Active processing mode there is the option to doze the CPU but keep the rest of the chip active; this is
particularly useful for radio transmit and receive operations, where the CPU operation is not required therefore saving
power.
18.2.1 CPU Doze
Whilst in doze mode, CPU operation is stopped but the chip remains powered and the digital peripherals continue to
run. Doze mode is entered through software and is terminated by any interrupt request. Once the interrupt service
routine has been executed, normal program execution resumes. Doze mode uses more power than sleep and deep
sleep modes but requires less time to restart and can therefore be used as a low power alternative to an idle loop.
Whilst in CPU doze the current associated with the CPU is not consumed, therefore the basic device current is
reduced as shown in the figures in Section 19.2.2.1.
18.3 Sleep Mode
The JN516x enters sleep mode through software control. In this mode most of the internal chip functions are
shutdown to save power, however the state of DIO pins are retained, including the output values and pull-up enables,
and this therefore preserves any interface to the outside world. 58 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
When entering into sleep mode, there is an option to retain the RAM contents throughout the sleep period. If the
wakeup timers are not to be used for a wakeup event and the application does not require them to run continually,
then power can be saved by switching off the 32kHz oscillator if selected as the 32kHz system clock through software
control. The oscillator will be restarted when a wakeup event occurs.
Whilst in sleep mode one of four possible events can cause a wakeup to occur: transitions on DIO inputs, expiry of
wakeup timers, pulse counters maturing or comparator events. If any of these events occur, and the relevant
interrupt is enabled, then an interrupt is generated that will cause a wakeup from sleep. It is possible for multiple
wakeup sources to trigger an event at the same instant and only one of them will be accountable for the wakeup
period. It is therefore necessary in software to remove all other pending wakeup events prior to requesting entry back
into sleep mode; otherwise, the device will re-awaken immediately.
When wakeup occurs, a similar sequence of events to the reset process described in Section 6.1 happens, including
the checking of the supply voltage by the Supply Voltage Monitor 6.4. The High-Speed RC oscillator is started up,
once stable the power to CPU system is enabled and the reset is removed. Software determines that this is a reset
from sleep and so commences with the wakeup process. If RAM contents were held through sleep, wakeup is quicker
as the software does not have to initialise RAM contents meaning the application can recommence more quickly. See
Section 19.3.5 for wake-up timings.
18.3.1 Wakeup Timer Event
The JN516x contains two 41-bit wakeup timers that are counters clocked from the 32kHz oscillator, and can be
programmed to generate a wake-up event. Following a wakeup event, the timers continue to run. These timers are
described in Section 11.3.
Timer events can be generated from both of the two timers; one is intended for use by the 802.15.4 protocol, the
other being available for use by the Application running on the CPU. These timers are available to run at any time,
even during sleep mode.
18.3.2 DIO Event
Any DIO pin when used as an input has the capability, by detecting a transition, to generate a wake-up event. Once
this feature has been enabled the type of transition can be specified (rising or falling edge). Even when groups of
DIO lines are configured as alternative functions such as the UARTs or Timers etc, any input line in the group can still
be used to provide a wakeup event. This means that an external device communicating over the UART can wakeup
a sleeping device by asserting its RTS signal pin (which is the CTS input of the JN516x).
18.3.3 Comparator Event
The comparator can generate a wakeup interrupt when a change in the relative levels of the positive and negative
inputs occurs. The ability to wakeup when continuously monitoring analogue signals is useful in ultra-low power
applications. For example, the JN516x can remain in sleep mode until the voltage drops below a threshold and then
be woken up to deal with the alarm condition and the comparator has a low current mode to facilitate this.
18.3.4 Pulse Counter
The JN516x contains two 16 bit pulse counters that can be programmed to generate a wake-up event. Following the
wakeup event the counters will continue to operate and therefore no pulse will be missed during the wake-up
process. These counters are described in Section 12.To minimize sleep current it is possible to disable the 32K RC
oscillator and still use the pulse counters to cause a wake-up event, provided debounce mode is not required.
18.4 Deep Sleep Mode
Deep sleep mode gives the lowest power consumption. All switchable power domains are off and most functions in
the VDD supply power domain are stopped, including the 32kHz RC oscillator. However, the Brown-Out Reset
remains active as well as all the DIO cells. This mode can be exited by a hardware reset on the RESETN pin, or an
enabled DIO or comparator wakeup event. In all cases, the wakeup sequence is equivalent to a power-up sequence,
with no knowledge retained from the previous time the device was awake.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 59

Appendix B Development Support
B.1 Crystal Oscillators
This Section covers some of the general background to crystal oscillators, to help the user make informed decisions
concerning the choice of crystal and the associated capacitors.
B.1.1 Crystal Equivalent Circuit
Cs
Lm Rm Cm
C1 C2
Where Cm is the motional capacitance
Lm is the motional inductance. This together with Cm defines the oscillation frequency (series)
Rm is the equivalent series resistance ( ESR ).
CS is the shunt or package capacitance and this is a parasitic
B.1.2 Crystal Load Capacitance
The crystal load capacitance is the total capacitance seen at the crystal pins, from all sources. As the load
capacitance (CL) affects the oscillation frequency by a process known as ‘pulling’, crystal manufacturers specify the
frequency for a given load capacitance only. A typical pulling coefficient is 15ppm/pF, to put this into context the
maximum frequency error in the IEEE802.15.4 specification is +/-40ppm for the transmitted signal. Therefore, it is
important for resonance at 32MHz exactly, that the specified load capacitance is provided.
The load capacitance can be calculated using:
CL =

C C
C C

×
Total capacitance CT1 = C1 + C1P + C1in
Where C1 is the capacitor component
C1P is the PCB parasitic capacitance. With the recommended layout this is about 1.6pF
C1in is the on-chip parasitic capacitance and is about 1.4pF typically.
Similarly for CT 2
Hence for a 9pF load capacitance, and a tight layout the external capacitors should be 15pF84 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013
B.1.3 Crystal ESR and Required Transconductance
The resistor in the crystal equivalent circuit represents the energy lost. To maintain oscillation, power must be
supplied by the amplifier, but how much? Firstly, the Pi connected capacitors C1 and C2 with CS from the crystal,
apply an impedance transformation to Rm, when viewed from the amplifier. This new value is given by:
2
ˆ
+ = L
S L m m
C
C C R R
The amplifier is a transconductance amplifier, which takes a voltage and produces an output current. The amplifier
together with the capacitors C1 and C2, form a circuit, which provides a negative resistance, when viewed from the
crystal. The value of which is given by:
2
1× 2 ×ω = T T
m
NEG
C C
g R
Where gm is the transconductance
ω is the frequency in rad/s
Derivations of these formulas can be easily found in textbooks.
In order to give quick and reliable oscillator start-up, a common rule of thumb is to set the amplifier negative
resistance to be a minimum of 4 times the effective crystal resistance. This gives

This can be used to give an equation for the required transconductance.

× + + × ≥ ω
Example: Using typical 32MHz crystal parameters of Rm =40Ω, CS =1pF and CT1 =CT 2 =18pF ( for a load
capacitance of 9pF), the equation above gives the required transconductance ( gm ) as 2.59mA/V. The JN516x has a
typical value for transconductance of 4.4mA/V
The example and equation illustrate the trade-off that exists between the load capacitance and crystal ESR. For
example, a crystal with a higher load capacitance can be used, but the value of max. ESR that can be tolerated is
reduced. Also note, that the circuit sensitivity to external capacitance [ C1 , C2 ] is a square law.
Meeting the criteria for start-up is only one aspect of the way these parameters affect performance, they also affect
the time taken during start-up to reach a given, (or full), amplitude. Unfortunately, there is no simple mathematical
model for this, but the trend is the same. Therefore, both a larger load capacitance and larger crystal ESR will give a
longer start-up time, which has the disadvantages of reduced battery life and increased latency. © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 85
B.2 32MHz Oscillator
The JN516x contains the necessary on-chip components to build a 32 MHz reference oscillator with the addition of an
external crystal resonator, two tuning capacitors. The schematic of these components are shown in Figure 52. The
two capacitors, C1 and C2, will typically be 15pF ±5% and use a COG dielectric. For a detailed specification of the
crystal required and factors affecting C1 and C2 see Appendix B.1. As with all crystal oscillators the PCB layout is
especially important, both to keep parasitic capacitors to a minimum and to reduce the possibility of PCB noise being
coupled into the oscillator.

As is stated above, not all combinations of crystal load capacitance and ESR are valid, and as explained in Appendix
B.1.3 there is a trade-off that exists between the load capacitance and crystal ESR to achieve reliable performance.
For this reason, we recommend that for a 9pF load capacitance crystals be specified with a maximum ESR of 40
ohms. For lower load capacitances the recommended maximum ESR rises, for example, CL=7pF the max ESR is 61
ohms. For the lower cost crystals in the large HC49 package, a load capacitance of 9 or 10pF is widely available and
the max ESR of 30 ohms specified by many manufacturers is acceptable. Also available in this package style, are
crystals with a load capacitance of 12pF, but in this case the max ESR required is 25 ohms or better.
Below is measurement data showing the variation of the crystal oscillator amplifier transconductance with
temperature and supply voltage, notice how small the variation is. Circuit techniques have been used to apply
compensation, such that the user need only design for nominal conditions.

B.3 32kHz Oscillator
In order to obtain more accurate sleep periods, the JN516x contains the necessary on-chip components to build an
optional 32kHz oscillator with the addition of an external 32.768kHz crystal and two tuning capacitors. The crystal
should be connected between XTAL32K_IN and XTAL32K_OUT (DIO9 and DIO10), with two equal capacitors to
ground, one on each pin. The schematic of these components are shown in Figure 53. The two capacitors, C1 and
C2, will typically be in the range 10 to 22pF ±5% and use a COG dielectric. As with all crystal oscillators the PCB
layout is especially important, both to keep parasitic capacitors to a minimum and to reduce the possibility of PCB
noise being coupled into the oscillator.
32KXTALIN 32KXTALOUT
JN516x
Figure 53: 32kHz Crystal Oscillator Connections
The electrical specification of the oscillator can be found in 19.3.10. The oscillator cell is flexible and can operate with
a range of commonly available 32kHz crystals with load capacitances from 6 to 12.5p, and ESR up to 80KΩ. It
achieves this by using automatic gain control (AGC), which senses the signal swing. As explained in Appendix B.1.3
there is a trade-off that exists between the load capacitance and crystal ESR to achieve reliable performance. The
use of an AGC function allows a wider range of crystal load capacitors and ESR’s to be accommodated than would
otherwise be possible. However, this benefit does mean the supply current varies with the supply voltage (VDD),
value of the total capacitance at each pin, and the crystal ESR. This is described in the table and graphs below.

B.4.2 PCB Design and Reflow Profile
PCB and land pattern designs are key to the reliability of any electronic circuit design.
The Institute for Interconnecting and Packaging Electronic Circuits (IPC) defines a number of standards for electronic
devices. One of these is the "Surface Mount Design and Land Pattern Standard" IPC-SM-782 [3], commonly referred
to as “IPC782". This specification defines the physical packaging characteristics and land patterns for a range of
surface mounted devices. IPC782 is also a useful reference document for general surface mount design techniques,
containing sections on design requirements, reliability and testability. NXP strongly recommends that this be referred
to when designing the PCB.
NXP also provide application note AN10366, “HVQFN application information” [6], which describes the reflow
soldering process. The suggested reflow profile, from that application note, is shown in Figure 55. The specific paste
manufacturers guidelines on peak flow temperature, soak times, time above liquids and ramp rates should also be
referenced.
Figure 55: Recommended Reflow Profile for Lead-free Solder Paste (SNAgCu) or PPF Lead Frame
B.4.3 Moisture Sensitivity Level (MSL)
If there is moisture trapped inside a package, and the package is exposed to a reflow temperature profile, the
moisture may turn into steam, which expands rapidly. This may cause damage to the inside of the package
(delamination), and it may result in a cracked semiconductor package body (the popcorn effect). A package’s MSL
depends on the package characteristics and on the temperature it is exposed to during reflow soldering. This is
explained in more detail in [7].
Depending on the damage after this test, an MSL of 1 (not sensitive to moisture) to 6 (very sensitive to moisture) is
attached to the semiconductor package.92 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013

CAN controller with two channels.
Digital peripherals:
SD/MMC memory card interface.
Up to 165 General Purpose I/O (GPIO) pins depending on the packaging with
configurable pull-up/down resistors, open-drain mode, and repeater mode. All
GPIOs are located on an AHB bus for fast access and support Cortex-M3
bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any
pin of ports 0 and 2 can be used to generate an interrupt.
Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0
and port 2 can be used as edge sensitive interrupt sources.
Four general purpose timers/counters with a total of eight capture inputs and ten
compare outputs. Each timer block has an external count input. Specific timer
events can be selected to generate DMA requests.
Quadrature encoder interface that can monitor one external quadrature encoder.
Two standard PWM/timer blocks with external count input option.

6.2 Pin description
I/O pins on the LPC178x/7x are 5 V tolerant and have input hysteresis unless otherwise
indicated in the table below. Crystal pins, power pins, and reference voltage pins are not
5 V tolerant. In addition, when pins are selected to be ADC inputs, they are no longer 5 V
tolerant and the input voltage must be limited to the voltage at the ADC positive reference
pin (VREFP).
All port pins Pn[m] are multiplexed, and the multiplexed functions appear in Table 3 in the
order defined by the FUNC bits of the corresponding IOCON register up to the highest
used function number. Each port pin can support up to eight multiplexed functions.
IOCON register FUNC values which are reserved are noted as ‘R’ in the pin configuration
table.

7. Functional description
7.1 Architectural overview
The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus. The I-code and D-code core buses are faster than the system bus and
are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for
instruction fetch (I-code) and one bus for data access (D-code). The use of two core
buses allows for simultaneous operations if concurrent operations target different devices.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
The LPC178x/7x use a multi-layer AHB matrix to connect the ARM Cortex-M3 buses and
other bus masters to peripherals in a flexible manner that optimizes performance by
allowing peripherals that are on different slaves ports of the matrix to be accessed
simultaneously by different bus masters.
7.2 ARM Cortex-M3 processor
The ARM Cortex-M3 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption. The ARM Cortex-M3 offers many new
features, including a Thumb-2 instruction set, low interrupt latency, hardware division,
hardware single-cycle multiply, interruptable/continuable multiple load and store
instructions, automatic state save and restore for interrupts, tightly integrated interrupt
controller with wake-up interrupt controller, and multiple core buses capable of
simultaneous accesses.
Pipeline techniques are employed so that all parts of the processing and memory systems
can operate continuously. Typically, while one instruction is being executed, its successor
is being decoded, and a third instruction is being fetched from memory.
The ARM Cortex-M3 processor is described in detail in the Cortex-M3 Technical
Reference Manual that can be found on official ARM website.
7.3 On-chip flash program memory
The LPC178x/7x contain up to 512 kB of on-chip flash program memory. A new two-port
flash accelerator maximizes performance for use with the two fast AHB-Lite buses.
7.4 EEPROM
The LPC178x/7x contains up to 4032 byte of on-chip byte-erasable and
byte-programmable EEPROM data memory.
7.5 On-chip SRAM
The LPC178x/7x contain a total of up to 96 kB on-chip static RAM data memory. This
includes the main 64 kB SRAM, accessible by the CPU and DMA controller on a
higher-speed bus, and up to two additional 16 kB each SRAM blocks situated on a
separate slave port on the AHB multilayer matrix.
This architecture allows CPU and DMA accesses to be spread over three separate RAMs
that can be accessed simultaneously.
7.6 Memory Protection Unit (MPU)
The LPC178x/7x have a Memory Protection Unit (MPU) which can be used to improve the
reliability of an embedded system by protecting critical data within the user application.
The MPU allows separating processing tasks by disallowing access to each other's data,
disabling access to memory regions, allowing memory regions to be defined as read-only
and detecting unexpected memory accesses that could potentially break the system.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 5 — 9 September 2014 42 of 122
NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
The MPU separates the memory into distinct regions and implements protection by
preventing disallowed accesses. The MPU supports up to eight regions each of which can
be divided into eight subregions. Accesses to memory locations that are not defined in the
MPU regions, or not permitted by the region setting, will cause the Memory Management
Fault exception to take place.
7.7 Memory map
The LPC178x/7x incorporate several distinct memory regions, shown in the following
figures. Figure 6 shows the overall map of the entire address space from the user
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 MB in size, and is divided to allow for up to 128 peripherals.
The APB peripheral area is 1 MB in size and is divided to allow for up to 64 peripherals.
Each peripheral of either type is allocated 16 kB of space. This allows simplifying the
address decoding for each peripheral.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
7.8 Nested Vectored Interrupt Controller (NVIC)
The NVIC is an integral part of the Cortex-M3. The tight coupling to the CPU allows for low
interrupt latency and efficient processing of late arriving interrupts.
7.8.1 Features
• Controls system exceptions and peripheral interrupts.
• On the LPC178x/7x, the NVIC supports 40 vectored interrupts.
• 32 programmable interrupt priority levels, with hardware priority level masking.
• Relocatable vector table.
• Non-Maskable Interrupt (NMI).
• Software interrupt generation.
7.8.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags may also represent more than one interrupt
source.
Any pin on port 0 and port 2 regardless of the selected function can be programmed to
generate an interrupt on a rising edge, a falling edge, or both.
7.9 Pin connect block
The pin connect block allows selected pins of the microcontroller to have more than one
function. Configuration registers control the multiplexers to allow connection between the
pin and the on-chip peripherals.
Peripherals should be connected to the appropriate pins prior to being activated and prior
to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is
not mapped to a related pin should be considered undefined.
Most pins can also be configured as open-drain outputs or to have a pull-up, pull-down, or
no resistor enabled.
7.10 External memory controller
Remark: Supported memory size and type and EMC bus width vary for different parts
(see Table 2). The EMC pin configuration for each part is shown in Table 7.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

(SCL) and a Serial Data Line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (e.g., an LCD driver) or a transmitter with the
capability to both receive and send information (such as memory). Transmitters and/or
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I2C is a multi-master bus and can be
controlled by more than one bus master connected to it.
7.22.1 Features
• All I2C-bus controllers can use standard GPIO pins with bit rates of up to 400 kbit/s

7.23 I2S-bus serial I/O controllers
The LPC178x/7x contain one I2S-bus interface. The I2S-bus provides a standard
communication interface for digital audio applications.
The I2S-bus specification defines a 3-wire serial bus using one data line, one clock line,
and one word select signal. The basic I2S connection has one master, which is always the
master, and one slave. The I2S interface on the LPC178x/7x provides a separate transmit
and receive channel, each of which can operate as either a master or a slave.
7.23.1 Features

7.24 CAN controller and acceptance filters
The LPC178x/7x contain one CAN controller with two channels.
The Controller Area Network (CAN) is a serial communications protocol which efficiently
supports distributed real-time control with a very high level of security. Its domain of
application ranges from high-speed networks to low cost multiplex wiring.
The CAN block is intended to support multiple CAN buses simultaneously, allowing the
device to be used as a gateway, switch, or router between two of CAN buses in industrial
or automotive applications.
Each CAN controller has a register structure similar to the NXP SJA1000 and the PeliCAN
Library block, but the 8-bit registers of those devices have been combined in 32-bit words
to allow simultaneous access in the ARM environment. The main operational difference is
that the recognition of received Identifiers, known in CAN terminology as Acceptance
Filtering, has been removed from the CAN controllers and centralized in a global
Acceptance Filter.
7.24.1 Features
• Two CAN controllers and buses.
• Data rates to 1 Mbit/s on each bus.
• 32-bit register and RAM access.
• Compatible with CAN specification 2.0B, ISO 11898-1.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

Standard Identifiers.
• FullCAN messages can generate interrupts.
7.25 General purpose 32-bit timers/external event counters
The LPC178x/7x include four 32-bit timer/counters.
The timer/counter is designed to count cycles of the system derived clock or an
externally-supplied clock. It can optionally generate interrupts, generate timed DMA
requests, or perform other actions at specified timer values, based on four match
registers. Each timer/counter also includes two capture inputs to trap the timer value when
an input signal transitions, optionally generating an interrupt.
7.25.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event may also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
7.26 Pulse Width Modulator (PWM)
The LPC178x/7x contain two standard PWMs.
The PWM is based on the standard Timer block and inherits all of its features, although
only the PWM function is pinned out on the LPC178x/7x. The Timer is designed to count
cycles of the system derived clock and optionally switch pins, generate interrupts or
perform other actions when specified timer values occur, based on seven match registers.
The PWM function is in addition to these features, and is based on match register events.
The ability to separately control rising and falling edge locations allows the PWM to be
used for more applications. For instance, multi-phase motor control typically requires
three non-overlapping PWM outputs with individual control of all three pulse widths and
positions.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

32-bit ARM Cortex-M3 microcontroller
Two match registers can be used to provide a single edge controlled PWM output. One
match register (PWMMR0) controls the PWM cycle rate, by resetting the count upon
match. The other match register controls the PWM edge position. Additional single edge
controlled PWM outputs require only one match register each, since the repetition rate is
the same for all PWM outputs. Multiple single edge controlled PWM outputs will all have a
rising edge at the beginning of each PWM cycle, when an PWMMR0 match occurs.
Three match registers can be used to provide a PWM output with both edges controlled.
Again, the PWMMR0 match register controls the PWM cycle rate. The other match
registers control the two PWM edge positions. Additional double edge controlled PWM
outputs require only two match registers each, since the repetition rate is the same for all
PWM outputs.
With double edge controlled PWM outputs, specific match registers control the rising and
falling edge of the output. This allows both positive going PWM pulses (when the rising
edge occurs prior to the falling edge), and negative going PWM pulses (when the falling
edge occurs prior to the rising edge).
7.26.1 Features
• LPC178x/7x has two PWM blocks with Counter or Timer operation (may use the
peripheral clock or one of the capture inputs as the clock source).
• Seven match registers allow up to 6 single edge controlled or 3 double edge
controlled PWM outputs, or a mix of both types. The match registers also allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Supports single edge controlled and/or double edge controlled PWM outputs. Single
edge controlled PWM outputs all go high at the beginning of each cycle unless the
output is a constant low. Double edge controlled PWM outputs can have either edge
occur at any position within a cycle. This allows for both positive going and negative
going pulses.
• Pulse period and width can be any number of timer counts. This allows complete
flexibility in the trade-off between resolution and repetition rate. All PWM outputs will
occur at the same repetition rate.
• Double edge controlled PWM outputs can be programmed to be either positive going
or negative going pulses.
• Match register updates are synchronized with pulse outputs to prevent generation of
erroneous pulses. Software must ‘release’ new match values before they can become
effective.
• May be used as a standard 32-bit timer/counter with a programmable 32-bit prescaler
if the PWM mode is not enabled.
7.27 Motor control PWM
The LPC178x/7x contain one motor control PWM.
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input is also provided that causes the LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

PWM to immediately release all motor drive outputs. At the same time, the motor control
PWM is highly configurable for other generalized timing, counting, capture, and compare
applications.
The maximum PWM speed is determined by the PWM resolution (n) and the operating
frequency f: PWM speed = f/2n (see Table 8).
7.28 Quadrature Encoder Interface (QEI)
Remark: The QEI is available on parts LPC1788/87/86 and LPC1778/77/76
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user can track the position, direction of rotation, and
velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
7.28.1 Features
• Tracks encoder position.
• Increments/decrements depending on direction.
• Programmable for 2 or 4 position counting.
• Velocity capture using built-in timer.
• Velocity compare function with “less than” interrupt.
• Uses 32-bit registers for position and velocity.
• Three position compare registers with interrupts.
• Index counter for revolution counting.
• Index compare register with interrupts.
• Can combine index and position interrupts to produce an interrupt for whole and
partial revolution displacement.
• Digital filter with programmable delays for encoder input signals.
• Can accept decoded signal inputs (clk and direction).
• Connected to APB.
7.29 ARM Cortex-M3 system tick timer
The ARM Cortex-M3 includes a system tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a 10 ms interval. In the LPC178x/7x, this timer can be
clocked from the internal AHB clock or from a device pin.

7.30 Windowed WatchDog Timer (WWDT)
The purpose of the watchdog is to reset the controller if software fails to periodically
service it within a programmable time window.
7.30.1 Features
• Internally resets chip if not periodically reloaded during the programmable time-out
period.
• Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
• Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect feed sequence causes reset or interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 24-bit timer with internal prescaler.
• Selectable time period from (Tcy(WDCLK) 256 4) to (Tcy(WDCLK) 224 4) in
multiples of Tcy(WDCLK) 4.
• The Watchdog Clock (WDCLK) source is a dedicated watchdog oscillator, which is
always running if the watchdog timer is enabled.
7.31 RTC and backup registers
The RTC is a set of counters for measuring time when system power is on, and optionally
when it is off. The RTC on the LPC178x/7x is designed to have very low power
consumption. The RTC will typically run from the main chip power supply conserving
battery power while the rest of the device is powered up. When operating from a battery,
the RTC will continue working down to 2.1 V. Battery power can be provided from a
standard 3 V lithium button cell.
An ultra-low power 32 kHz oscillator provides a 1 Hz clock to the time counting portion of
the RTC, moving most of the power consumption out of the time counting function.
The RTC includes a calibration mechanism to allow fine-tuning the count rate in a way
that will provide less than 1 second per day error when operated at a constant voltage and
temperature.
The RTC contains a small set of backup registers (20 bytes) for holding data while the
main part of the LPC178x/7x is powered off.
The RTC includes an alarm function that can wake up the LPC178x/7x from all reduced
power modes with a time resolution of 1 s.
7.31.1 Features
• Measures the passage of time to maintain a calendar and clock.
• Ultra low power design to support battery powered systems.
• Provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and
Day of Year.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
• Dedicated power supply pin can be connected to a battery or to the main 3.3 V.
• Periodic interrupts can be generated from increments of any field of the time registers.
• Backup registers (20 bytes) powered by VBAT.
• RTC power supply is isolated from the rest of the chip.
7.32 Event monitor/recorder
The event monitor/recorder allows recording of tampering events in sealed product
enclosures. Sensors report any attempt to open the enclosure, or to tamper with the
device in any other way. The event monitor/recorder stores records of such events when
the device is powered only by the backup battery.
7.32.1 Features
• Supports three digital event inputs in the VBAT power domain.
• An event is defined as a level change at the digital event inputs.
• For each event channel, two timestamps mark the first and the last occurrence of an
event. Each channel also has a dedicated counter tracking the total number of events.
Timestamp values are taken from the RTC.
• Runs in VBAT power domain, independent of system power supply. The
event/recorder/monitor can therefore operate in Deep power-down mode.
• Very low power consumption.
• Interrupt available if system is running.
• A qualified event can be used as a wake-up trigger.
• State of event interrupts accessible by software through GPIO.
7.33 Clocking and power control
7.33.1 Crystal oscillators
The LPC178x/7x include four independent oscillators. These are the main oscillator, the
IRC oscillator, the watchdog oscillator, and the RTC oscillator.
Following reset, the LPC178x/7x will operate from the Internal RC oscillator until switched
by software. This allows systems to operate without any external crystal and the boot
loader code to operate at a known frequency.
See Figure 7 for an overview of the LPC178x/7x clock generation.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
7.33.1.1 Internal RC oscillator
The IRC may be used as the clock that drives the PLL and subsequently the CPU. The
nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire
voltage and temperature range.
Upon power-up or any chip reset, the LPC178x/7x use the IRC as the clock source.
Software may later switch to one of the other available clock sources.
7.33.1.2 Main oscillator
The main oscillator can be used as the clock source for the CPU, with or without using the
PLL. The main oscillator also provides the clock source for the alternate PLL1.
The main oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the main
PLL. The clock selected as the PLL input is PLLCLKIN. The ARM processor clock
frequency is referred to as CCLK elsewhere in this document. The frequencies of
PLLCLKIN and CCLK are the same value unless the PLL is active and connected. The
clock frequency for each peripheral can be selected individually and is referred to as
PCLK. Refer to Section 7.33.2 for additional information.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
7.33.1.3 RTC oscillator
The RTC oscillator provides a 1 Hz clock to the RTC and a 32 kHz clock output that can
be output on the CLKOUT pin in order to allow trimming the RTC oscillator without
interference from a probe.
7.33.1.4 Watchdog oscillator
The Watchdog Timer has a dedicated watchdog oscillator that provides a 500 kHz clock to
the Watchdog Timer. The watchdog oscillator is always running if the Watchdog Timer is
enabled. The Watchdog oscillator clock can be output on the CLKOUT pin in order to
allow observe its frequency.
In order to allow Watchdog Timer operation with minimum power consumption, which can
be important in reduced power modes, the Watchdog oscillator frequency is not tightly
controlled. The Watchdog oscillator frequency will vary over temperature and power
supply within a particular part, and may vary by processing across different parts. This
variation should be taken into account when determining Watchdog reload values.
Within a particular part, temperature and power supply variations can produce up to a
17 % frequency variation. Frequency variation between devices under the same
operating conditions can be up to 30 %.
7.33.2 Main PLL (PLL0) and Alternate PLL (PLL1)
PLL0 (also called the Main PLL) and PLL1 (also called the Alternate PLL) are functionally
identical but have somewhat different input possibilities and output connections. These
possibilities are shown in Figure 7. The Main PLL can receive its input from either the IRC
or the main oscillator and can potentially be used to provide the clocks to nearly
everything on the device. The Alternate PLL receives its input only from the main oscillator
and is intended to be used as an alternate source of clocking to the USB. The USB has
timing needs that may not always be filled by the Main PLL.
Both PLLs are disabled and powered off on reset. If the Alternate PLL is left disabled, the
USB clock can be supplied by PLL0 if everything is set up to provide 48 MHz to the USB
clock through that route. The source for each clock must be selected via the CLKSEL
registers and can be further reduced by clock dividers as needed.
PLL0 accepts an input clock frequency from either the IRC or the main oscillator. If only
the Main PLL is used, then its output frequency must be an integer multiple of all other
clocks needed in the system. PLL1 takes its input only from the main oscillator, requiring
an external crystal in the range of 10 to 25 MHz. In each PLL, the Current Controlled
Oscillator (CCO) operates in the range of 156 MHz to 320 MHz, so there are additional
dividers to bring the output down to the desired frequencies. The minimum output divider
value is 2, insuring that the output of the PLLs have a 50 % duty cycle.
If the USB is used, the possibilities for the CPU clock and other clocks will be limited by
the requirements that the frequency be precise and very low jitter, and that the PLL0
output must be a multiple of 48 MHz. Even multiples of 48 MHz that are within the
operating range of the PLL are 192 MHz and 288 MHz. Also, only the main oscillator in
conjunction with the PLL can meet the precision and jitter specifications for USB. It is due
to these limitations that the Alternate PLL is provided.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 5 — 9 September 2014 63 of 122
NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
The alternate PLL accepts an input clock frequency from the main oscillator in the range
of 10 MHz to 25 MHz only. When used as the USB clock, the input frequency is multiplied
up to a multiple of 48 MHz (192 MHz or 288 MHz as described above).
7.33.3 Wake-up timer
The LPC178x/7x begin operation at power-up and when awakened from Power-down
mode by using the 12 MHz IRC oscillator as the clock source. This allows chip operation
to resume quickly. If the main oscillator or the PLL is needed by the application, software
will need to enable these features and wait for them to stabilize before they are used as a
clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of reset, and
whenever any of the aforementioned functions are turned off for any reason. Since the
oscillator and other functions are turned off during Power-down mode, any wake-up of the
processor from Power-down mode makes use of the wake-up Timer.
The wake-up timer monitors the crystal oscillator to check whether it is safe to begin code
execution. When power is applied to the chip, or when some event caused the chip to exit
Power-down mode, some time is required for the oscillator to produce a signal of sufficient
amplitude to drive the clock logic. The amount of time depends on many factors, including
the rate of VDD(3V3) ramp (in the case of power on), the type of crystal and its electrical
characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g.,
capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.
7.33.4 Power control
The LPC178x/7x support a variety of power control features. There are four special
modes of processor power reduction: Sleep mode, Deep-sleep mode, Power-down mode,
and Deep power-down mode. The CPU clock rate may also be controlled as needed by
changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider
value. This allows a trade-off of power versus processing speed based on application
requirements. In addition, the peripheral power control allows shutting down the clocks to
individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all
dynamic power use in any peripherals that are not required for the application. Each of the
peripherals has its own clock divider which provides even better power control.
The integrated PMU (Power Management Unit) automatically adjusts internal regulators
to minimize power consumption during Sleep, Deep-sleep, Power-down, and Deep
power-down modes.
The LPC178x/7x also implement a separate power domain to allow turning off power to
the bulk of the device while maintaining operation of the RTC and a small set of registers
for storing data during any of the power-down modes.
7.33.4.1 Sleep mode
When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep
mode does not need any special sequence other than re-enabling the clock to the ARM
core.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 5 — 9 September 2014 64 of 122
NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
In Sleep mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Sleep mode and may generate
interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
The DMA controller can continue to work in Sleep mode and has access to the peripheral
RAMs and all peripheral registers. The flash memory and the main SRAM are not
available in Sleep mode, they are disabled in order to save power.
Wake-up from Sleep mode will occur whenever any enabled interrupt occurs.
7.33.4.2 Deep-sleep mode
In Deep-sleep mode, the oscillator is shut down and the chip receives no internal clocks.
The processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Deep-sleep mode and the logic levels of chip pins remain static.
The output of the IRC is disabled but the IRC is not powered down to allow fast wake-up.
The RTC oscillator is not stopped because the RTC interrupts may be used as the
wake-up source. The PLL is automatically turned off and disconnected. The clock divider
registers are automatically reset to zero.
The Deep-sleep mode can be terminated and normal operation resumed by either a
Reset or certain specific interrupts that are able to function without clocks. Since all
dynamic operation of the chip is suspended, Deep-sleep mode reduces chip power
consumption to a very low value. Power to the flash memory is left on in Deep-sleep
mode, allowing a very quick wake-up.
Wake-up from Deep-sleep mode can initiated by the NMI, External Interrupts EINT0
through EINT3, GPIO interrupts, the Ethernet Wake-on-LAN interrupt, Brownout Detect,
an RTC Alarm interrupt, a USB input pin transition (USB activity interrupt), a CAN input
pin transition, or a Watchdog Timer time-out, when the related interrupt is enabled.
Wake-up will occur whenever any enabled interrupt occurs.
On wake-up from Deep-sleep mode, the code execution and peripherals activities will
resume after four cycles expire if the IRC was used before entering Deep-sleep mode. If
the main external oscillator was used, the code execution will resume when 4096 cycles
expire. PLL and clock dividers need to be reconfigured accordingly.
7.33.4.3 Power-down mode
Power-down mode does everything that Deep-sleep mode does but also turns off the
power to the IRC oscillator and the flash memory. This saves more power but requires
waiting for resumption of flash operation before execution of code or data access in the
flash memory can be accomplished.
When the chip enters Power-down mode, the IRC, the main oscillator, and all clocks are
stopped. The RTC remains running if it has been enabled and RTC interrupts may be
used to wake up the CPU. The flash is forced into Power-down mode. The PLLs are
automatically turned off and the clock selection multiplexers are set to use the system
clock sysclk (the reset state). The clock divider control registers are automatically reset to
zero. If the Watchdog timer is running, it will continue running in Power-down mode.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 5 — 9 September 2014 65 of 122
NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
On the wake-up of Power-down mode, if the IRC was used before entering Power-down
mode, it will take IRC 60 s to start-up. After this, four IRC cycles will expire before the
code execution can then be resumed if the code was running from SRAM. In the
meantime, the flash wake-up timer then counts 12 MHz IRC clock cycles to make the
100 s flash start-up time. When it times out, access to the flash will be allowed. Users
need to reconfigure the PLL and clock dividers accordingly.
7.33.4.4 Deep power-down mode
In Deep power-down mode, power is shut off to the entire chip with the exception of the
RTC module and the RESET pin.
To optimize power conservation, the user has the additional option of turning off or
retaining power to the 32 kHz oscillator. It is also possible to use external circuitry to turn
off power to the on-chip regulator via the VDD(REG)(3V3) pins and/or the I/O power via the
VDD(3V3) pins after entering Deep Power-down mode. Power must be restored before
device operation can be restarted.
The LPC178x/7x can wake up from Deep power-down mode via the RESET pin or an
alarm match event of the RTC.
7.33.4.5 Wake-up Interrupt Controller (WIC)
The WIC allows the CPU to automatically wake up from any enabled priority interrupt that
can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep
power-down modes.
The WIC works in connection with the Nested Vectored Interrupt Controller (NVIC). When
the CPU enters Deep-sleep, Power-down, or Deep power-down mode, the NVIC sends a
mask of the current interrupt situation to the WIC.This mask includes all of the interrupts
that are both enabled and of sufficient priority to be serviced immediately. With this
information, the WIC simply notices when one of the interrupts has occurred and then it
wakes up the CPU.
The WIC eliminates the need to periodically wake up the CPU and poll the interrupts
resulting in additional power savings.
7.33.5 Peripheral power control
A power control for peripherals feature allows individual peripherals to be turned off if they
are not needed in the application, resulting in additional power savings.
7.33.6 Power domains
The LPC178x/7x provide two independent power domains that allow the bulk of the
device to have power removed while maintaining operation of the RTC and the backup
registers.
On the LPC178x/7x, I/O pads are powered by VDD(3V3), while VDD(REG)(3V3) powers the
on-chip voltage regulator which in turn provides power to the CPU and most of the
peripherals.
Depending on the LPC178x/7x application, a design can use two power options to
manage power consumption.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 5 — 9 September 2014 66 of 122
NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
The first option assumes that power consumption is not a concern and the design ties the
VDD(3V3) and VDD(REG)(3V3) pins together. This approach requires only one 3.3 V power
supply for both pads, the CPU, and peripherals. While this solution is simple, it does not
support powering down the I/O pad ring “on the fly” while keeping the CPU and
peripherals alive.
The second option uses two power supplies; a 3.3 V supply for the I/O pads (VDD(3V3)) and
a dedicated 3.3 V supply for the CPU (VDD(REG)(3V3)). Having the on-chip voltage regulator
powered independently from the I/O pad ring enables shutting down of the I/O pad power
supply “on the fly” while the CPU and peripherals stay active.
The VBAT pin supplies power only to the RTC domain. The RTC operates at very low
power, which can be supplied by an external battery. The device core power
(VDD(REG)(3V3)) is used to operate the RTC whenever VDD(REG)(3V3) is present. There is no
power drain from the RTC battery when VDD(REG)(3V3) is at nominal levels and
VDD(REG)(3V3) > VBAT.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
7.34 System control
7.34.1 Reset
Reset has four sources on the LPC178x/7x: the RESET pin, the Watchdog reset,
Power-On Reset (POR), and the BrownOut Detection (BOD) circuit. The RESET pin is a
Schmitt trigger input pin. Assertion of chip Reset by any source, once the operating
voltage attains a usable level, starts the Wake-up timer (see description in
Section 7.33.3), causing reset to remain asserted until the external Reset is de-asserted,
the oscillator is running, a fixed number of clocks have passed, and the flash controller
has completed its initialization.
When the internal Reset is removed, the processor begins executing at address 0, which
is initially the Reset vector mapped from the boot block. At that point, all of the processor
and peripheral registers have been initialized to predetermined values.
7.34.2 Brownout detection
The LPC178x/7x include 2-stage monitoring of the voltage on the VDD(REG)(3V3) pins. If this
voltage falls below 2.2 V (typical), the BOD asserts an interrupt signal to the Vectored
Interrupt Controller. This signal can be enabled for interrupt in the Interrupt Enable
Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the
signal by reading a dedicated status register.
The second stage of low-voltage detection asserts a reset to inactivate the LPC178x/7x
when the voltage on the VDD(REG)(3V3) pins falls below 1.85 V (typical). This reset prevents
alteration of the flash as operation of the various elements of the chip would otherwise
become unreliable due to low voltage. The BOD circuit maintains this reset down below
1 V, at which point the power-on reset circuitry maintains the overall reset.
Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event
loop to sense the condition.
7.34.3 Code security (Code Read Protection - CRP)
This feature of the LPC178x/7x allows user to enable different levels of security in the
system so that access to the on-chip flash and use of the JTAG and ISP can be restricted.
When needed, CRP is invoked by programming a specific pattern into a dedicated flash
location. IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too.
It is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
7.34.4 APB interface
The APB peripherals are split into two separate APB buses in order to distribute the bus
bandwidth and thereby reducing stalls caused by contention between the CPU and the
GPDMA controller.
7.34.5 AHB multilayer matrix
The LPC178x/7x use an AHB multilayer matrix. This matrix connects the instruction
(I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the
main (64 kB) SRAM, and the Boot ROM. The GPDMA can also access all of these
memories. Additionally, the matrix connects the CPU system bus and all of the DMA
controllers to the various peripheral functions.
7.34.6 External interrupt inputs
The LPC178x/7x include up to 30 edge sensitive interrupt inputs combined with one level
sensitive external interrupt input as selectable pin function. The external interrupt input
can optionally be used to wake up the processor from Power-down mode.
7.34.7 Memory mapping control
The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table
to alternate locations in the memory map. This is controlled via the Vector Table Offset
Register contained in the NVIC.
The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address
space. The vector table must be located on a 128 word (512 byte) boundary because the
NVIC on the LPC178x/7x is configured for 128 total interrupts.
7.35 Debug control
Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four
watch points.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.LPC178X_7X All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

8. Limiting values
[1] The following applies to the limiting values:
a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated
maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless
otherwise noted.
[2] Including voltage on outputs in 3-state mode.
[3] Not to exceed 4.6 V.
[4] The maximum non-operating storage temperature is different than the temperature for required shelf life which should be determined
based on the required shelf lifetime. Please refer to the JEDEC spec for further details.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7. Functional description
7.1 Architectural overview
The ARM Cortex-M4 includes three AHB-Lite buses: the system bus, the I-CODE bus,
and the D-code bus. The I-CODE and D-code core buses allow for concurrent code and
data accesses from different slave ports.
The LPC4350/30/20/10 use a multi-layer AHB matrix to connect the ARM Cortex-M4
buses and other bus masters to peripherals in a flexible manner that optimizes
performance by allowing peripherals that are on different slaves ports of the matrix to be
accessed simultaneously by different bus masters.
An ARM Cortex-M0 co-processor is included in the LPC4350/30/20/10, capable of
off-loading the main ARM Cortex-M4 application processor. Most peripheral interrupts are
connected to both processors. The processors communicate with each other via an
interprocessor communication protocol.
7.2 ARM Cortex-M4 processor
The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture
with separate local instruction and data buses as well as a third bus for peripherals, and
includes an internal prefetch unit that supports speculative branching. The ARM
Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A
hardware floating-point processor is integrated in the core. The processor includes an
NVIC with up to 53 interrupts.
7.3 ARM Cortex-M0 co-processor
The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high
performance and very low-power consumption. The ARM Cortex-M0 co-processor uses a
3-stage pipeline von-Neumann architecture and a small but powerful instruction set
providing high-end processing hardware. The co-processor incorporates an NVIC with 32
interrupts.
7.4 Interprocessor communication
The ARM Cortex-M4 and ARM Cortex-M0 interprocessor communication is based on
using shared SRAM as mailbox and one processor raising an interrupt on the other
processor's NVIC, for example after it has delivered a new message in the mailbox. The
receiving processor can reply by raising an interrupt on the sending processor's NVIC to
acknowledge the message.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.5 AHB multilayer matrix
7.6 Nested Vectored Interrupt Controller (NVIC)
The NVIC is an integral part of the Cortex-M4. The tight coupling to the CPU allows for low
interrupt latency and efficient processing of late arriving interrupts.
The ARM Cortex-M0 co-processor has its own NVIC with 32 vectored interrupts. Most
peripheral interrupts are shared between the Cortex-M0 and Cortex-M4 NVICs.

32-bit ARM Cortex-M4/M0 microcontroller
7.6.1 Features
• Controls system exceptions and peripheral interrupts.
• The Cortex-M4 NVIC supports up to 53 vectored interrupts.
• Eight programmable interrupt priority levels with hardware priority level masking.
• Relocatable vector table.
• Non-Maskable Interrupt (NMI).
• Software interrupt generation.
7.6.2 Interrupt sources
Each peripheral device has one interrupt line connected to the NVIC but may have several
interrupt flags. Individual interrupt flags can represent more than one interrupt source.
7.7 System Tick timer (SysTick)
The ARM Cortex-M4 includes a system tick timer (SysTick) that is intended to generate a
dedicated SYSTICK exception at a 10 ms interval.
Remark: The SysTick is not included in the ARM Cortex-M0 core.
7.8 Event router
The event router combines various internal signals, interrupts, and the external interrupt
pins (WAKEUP[3:0]) to create an interrupt in the NVIC, if enabled. In addition, the event
router creates a wake-up signal to the ARM core and the CCU for waking up from Sleep,
Deep-sleep, Power-down, and Deep power-down modes. Individual events can be
configured as edge or level sensitive and can be enabled or disabled in the event router.
The event router can be battery powered.
The following events if enabled in the event router can create a wake-up signal from
sleep, deep-sleep, power-down, and deep power-down modes and/or create an interrupt:
• External pins WAKEUP0/1/2/3 and RESET
• Alarm timer, RTC (32 kHz oscillator running)
The following events if enabled in the event router can create a wake-up signal from sleep
mode only and/or create an interrupt:
• WWDT, BOD interrupts
• C_CAN0/1 and QEI interrupts
• Ethernet, USB0, USB1 signals
• Selected outputs of combined timers (SCTimer/PWM and timer0/1/3)
Remark: Any interrupt can wake up the ARM Cortex-M4 from sleep mode if enabled in
the NVIC.
7.9 Global Input Multiplexer Array (GIMA)
The GIMA routes signals to event-driven peripheral targets like the SCTimer/PWM,
timers, event router, or the ADCs.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.9.1 Features
• Single selection of a source.
• Signal inversion.
• Can capture a pulse if the input event source is faster than the target clock.
• Synchronization of input event and target clock.
• Single-cycle pulse generation for target.
7.10 On-chip static RAM
The LPC4350/30/20/10 support up to 200 kB local SRAM and an additional 64 kB AHB
SRAM with separate bus master access for higher throughput and individual power
control for low-power operation.
7.11 In-System Programming (ISP)
In-System Programming (ISP) means programming or reprogramming the on-chip SRAM
memory, using the boot loader software and the USART0 serial port. ISP can be
performed when the part resides in the end-user board. ISP loads data into on-chip SRAM
and execute code from on-chip SRAM.
7.12 Boot ROM
The internal ROM memory is used to store the boot code of the LPC4350/30/20/10. After
a reset, the ARM processor will start its code execution from this memory.
The boot ROM memory includes the following features:
• The ROM memory size is 64 kB.
• Supports booting from UART interfaces and external static memory such as NOR
flash, quad SPI flash, and USB0 and USB1.
• Includes API for OTP programming.
• Includes a flexible USB device stack that supports Human Interface Device (HID),
Mass Storage Class (MSC), and Device Firmware Upgrade (DFU) drivers.
Several boot modes are available depending on the values of the OTP bits BOOT_SRC. If
the OTP memory is not programmed or the BOOT_SRC bits are all zero, the boot mode is
determined by the states of the boot pins P2_9, P2_8, P1_2, and P1_1.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7.14 One-Time Programmable (OTP) memory
The OTP provides 64 bit + 256 bit One-Time Programmable (OTP) memory for
general-purpose use.
7.15 General-Purpose I/O (GPIO)
The LPC4350/30/20/10 provide eight GPIO ports with up to 31 GPIO pins each.
Device pins that are not connected to a specific peripheral function are controlled by the
GPIO registers. Pins may be dynamically configured as inputs or outputs. Separate
registers allow setting or clearing any number of outputs simultaneously. The value of the
output register may be read back as well as the current state of the port pins.
All GPIO pins default to inputs with pull-up resistors enabled and input buffer disabled on
reset. The input buffer must be turned on in the system control block SFS register before
the GPIO input can be read.
7.15.1 Features
• Accelerated GPIO functions:
– GPIO registers are located on the AHB so that the fastest possible I/O timing can
be achieved.
– Mask registers allow treating sets of port bits as a group, leaving other bits
unchanged.
– All GPIO registers are byte and half-word addressable.
– Entire port value can be written in one instruction.
• Bit-level set and clear registers allow a single instruction set or clear of any number of
bits in one port.
• Direction control of individual bits.
• Up to eight GPIO pins can be selected from all GPIO pins to create an edge- or
level-sensitive GPIO interrupt request (GPIO interrupts).
• Two GPIO group interrupts can be triggered by any pin or pins in each port (GPIO
group0 and group1 interrupts).
7.16 Configurable digital peripherals
7.16.1 State Configurable Timer (SCTimer/PWM) subsystem
The SCTimer/PWM allows a wide variety of timing, counting, output modulation, and input
capture operations. The inputs and outputs of the SCTimer/PWM are shared with the
capture and match inputs/outputs of the 32-bit general-purpose counter/timers.
The SCTimer/PWM can be configured as two 16-bit counters or a unified 32-bit counter. In
the two-counter case, in addition to the counter value the following operational elements
are independent for each half:
• State variable
• Limit, halt, stop, and start conditions
• Values of Match/Capture registers, plus reload or capture control valuesLPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 4.2 — 18 August 2014 69 of 155
NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
In the two-counter case, the following operational elements are global to the
SCTimer/PWM, but the last three can use match conditions from either counter:
• Clock selection
• Inputs
• Events
• Outputs
• Interrupts
7.16.1.1 Features
• Two 16-bit counters or one 32-bit counter.
• Counters clocked by bus clock or selected input.
• Counters can be configured as up-counters or up-down counters.
• State variable allows sequencing across multiple counter cycles.
• Event combines input or output condition and/or counter match in a specified state.
• Events control outputs and interrupts.
• Selected events can limit, halt, start, or stop a counter.
• Supports:
– up to 8 inputs
– 16 outputs
– 16 match/capture registers
– 16 events
– 32 states
7.16.2 Serial GPIO (SGPIO)
The Serial GPIOs offer standard GPIO functionality enhanced with features to accelerate
serial stream processing.
7.16.2.1 Features
• Each SGPIO input/output slice can be used to perform a serial to parallel or parallel to
serial data conversion.
• 16 SGPIO input/output slices each with a 32-bit FIFO that can shift the input value
from a pin or an output value to a pin with every cycle of a shift clock.
• Each slice is double-buffered.
• Interrupt is generated on a full FIFO, shift clock, or pattern match.
• Slices can be concatenated to increase buffer size.
• Each slice has a 32-bit pattern match filter.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.17 AHB peripherals
7.17.1 General-Purpose DMA (GPDMA)
The DMA controller allows peripheral-to memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receives. The
source and destination areas can each be either a memory region or a peripheral for
master 1, but only memory for master 0.
7.17.1.1 Features
• Eight DMA channels. Each channel can support a unidirectional transfer.
• 16 DMA request lines.
• Single DMA and burst DMA request signals. Each peripheral connected to the DMA
Controller can assert either a burst DMA request or a single DMA request. The DMA
burst size is set by programming the DMA Controller.
• Memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral transfers are supported.
• Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
• Hardware DMA channel priority.
• AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
• Two AHB bus masters for transferring data. These interfaces transfer data when a
DMA request goes active. Master 1 can access memories and peripherals, master 0
can access memories only.
• 32-bit AHB master bus width.
• Incrementing or non-incrementing addressing for source and destination.
• Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
• Internal four-word FIFO per channel.
• Supports 8, 16, and 32-bit wide transactions.
• Big-endian and little-endian support. The DMA Controller defaults to little-endian
mode on reset.
• An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
• Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
7.17.2 SPI Flash Interface (SPIFI)
The SPI Flash Interface allows low-cost serial flash memories to be connected to the ARM
Cortex-M4 processor with little performance penalty compared to parallel flash devices
with higher pin count. LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
Product data sheet Rev. 4.2 — 18 August 2014 71 of 155
NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
After a few commands configure the interface at startup, the entire flash content is
accessible as normal memory using byte, halfword, and word accesses by the processor
and/or DMA channels. Simple sequences of commands handle erasing and
programming.
Many serial flash devices use a half-duplex command-driven SPI protocol for device setup
and initialization and then move to a half-duplex, command-driven 4-bit protocol for
normal operation. Different serial flash vendors and devices accept or require different
commands and command formats. SPIFI provides sufficient flexibility to be compatible
with common flash devices and includes extensions to help insure compatibility with future
devices.
7.17.2.1 Features
• Interfaces to serial flash memory in the main memory map.
• Supports classic and 4-bit bidirectional serial protocols.
• Half-duplex protocol compatible with various vendors and devices.
• Quad SPI Flash Interface (SPIFI) with 1-, 2-, or 4-bit data at rates of up to
52 MB per second.
• Supports DMA access.
7.17.3 SD/MMC card interface
The SD/MMC card interface supports the following modes to control:
• Secure Digital memory (SD version 3.0)
• Secure Digital I/O (SDIO version 2.0)
• Consumer Electronics Advanced Transport Architecture (CE-ATA version 1.1)
• MultiMedia Cards (MMC version 4.4)
7.17.4 External Memory Controller (EMC)
The LPC4350/30/20/10 EMC is a Memory Controller peripheral offering support for
asynchronous static memory devices such as RAM, ROM, and NOR flash. In addition, it
can be used as an interface with off-chip memory-mapped devices and peripherals.

The I2C-bus is bidirectional for inter-IC control using only two wires: a Serial Clock line
(SCL) and a Serial Data line (SDA). Each device is recognized by a unique address and
can operate as either a receiver-only device (for example an LCD driver) or a transmitter
with the capability to both receive and send information (such as memory). Transmitters
and/or receivers can operate in either master or slave mode, depending on whether the
chip has to initiate a data transfer or is only addressed. The I2C is a multi-master bus and
can be controlled by more than one bus master connected to it.

Remark: The LPC4350/30/20/10 contain two C_CAN controllers.
Controller Area Network (CAN) is the definition of a high performance communication
protocol for serial data communication. The C_CAN controller is designed to provide a full
implementation of the CAN protocol according to the CAN Specification Version 2.0B. The

7.19 Counter/timers and motor control
7.19.1 General purpose 32-bit timers/external event counters
The LPC4350/30/20/10 include four 32-bit timer/counters. The timer/counter is designed
to count cycles of the system derived clock or an externally-supplied clock. It can
optionally generate interrupts, generate timed DMA requests, or perform other actions at
specified timer values, based on four match registers. Each timer/counter also includes
two capture inputs to trap the timer value when an input signal transitions, optionally
generating an interrupt.
7.19.1.1 Features
• A 32-bit timer/counter with a programmable 32-bit prescaler.
• Counter or timer operation.
• Two 32-bit capture channels per timer, that can take a snapshot of the timer value
when an input signal transitions. A capture event can also generate an interrupt.
• Four 32-bit match registers that allow:
– Continuous operation with optional interrupt generation on match.
– Stop timer on match with optional interrupt generation.
– Reset timer on match with optional interrupt generation.
• Up to four external outputs corresponding to match registers, with the following
capabilities:
– Set LOW on match.
– Set HIGH on match.
– Toggle on match.
– Do nothing on match.
• Up to two match registers can be used to generate timed DMA requests.
7.19.2 Motor control PWM
The motor control PWM is a specialized PWM supporting 3-phase motors and other
combinations. Feedback inputs are provided to automatically sense rotor position and use
that information to ramp speed up or down. An abort input causes the PWM to release all
motor drive outputs immediately . At the same time, the motor control PWM is highly
configurable for other generalized timing, counting, capture, and compare applications.
7.19.3 Quadrature Encoder Interface (QEI)
A quadrature encoder, also known as a 2-channel incremental encoder, converts angular
displacement into two pulse signals. By monitoring both the number of pulses and the
relative phase of the two signals, the user code can track the position, direction of rotation,
and velocity. In addition, a third channel, or index signal, can be used to reset the position
counter. The quadrature encoder interface decodes the digital pulses from a quadrature
encoder wheel to integrate position over time and determine direction of rotation. In
addition, the QEI can capture the velocity of the encoder wheel.
7.19.3.1 Features
• Tracks encoder position.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.19.4 Repetitive Interrupt (RI) timer
The repetitive interrupt timer provides a free-running 32-bit counter which is compared to
a selectable value, generating an interrupt when a match occurs. Any bits of the
timer/compare function can be masked such that they do not contribute to the match
detection. The repetitive interrupt timer can be used to create an interrupt that repeats at
predetermined intervals.
7.19.4.1 Features
• 32-bit counter. Counter can be free-running or be reset by a generated interrupt.
• 32-bit compare value.
• 32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This mechanism allows for combinations not possible
with a simple compare.
7.19.5 Windowed WatchDog Timer (WWDT)
The purpose of the watchdog is to reset the controller if software fails to periodically
service it within a programmable time window.
7.19.5.1 Features
• Internally resets chip if not periodically reloaded during the programmable time-out
period.
• Optional windowed operation requires reload to occur between a minimum and
maximum time period, both programmable.
• Optional warning interrupt can be generated at a programmable time prior to
watchdog time-out.
• Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be
disabled.
• Incorrect feed sequence causes reset or interrupt if enabled.
• Flag to indicate watchdog reset.
• Programmable 24-bit timer with internal prescaler.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

7.21 Peripherals in the RTC power domain
7.21.1 RTC
The Real-Time Clock (RTC) is a set of counters for measuring time when system power is
on, and optionally when it is off. It uses little power when the CPU does not access its
registers, especially in the reduced power modes. A separate 32 kHz oscillator clocks the
RTC. The oscillator produces a 1 Hz internal time reference and is powered by its own
power supply pin, VBAT.
7.21.1.1 Features
• Measures the passage of time to maintain a calendar and clock. Provides seconds,
minutes, hours, day of month, month, year, day of week, and day of year.
• Ultra-low power design to support battery powered systems. Uses power from the
CPU power supply when it is present.
• Dedicated battery power supply pin.
• RTC power supply is isolated from the rest of the chip.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

32-bit ARM Cortex-M4/M0 microcontroller
• Calibration counter allows adjustment to better than 1 sec/day with 1 sec resolution.
• Periodic interrupts can be generated from increments of any field of the time registers.
• Alarm interrupt can be generated for a specific date/time.
7.21.2 Alarm timer
The alarm timer is a 16-bit timer and counts down at 1 kHz from a preset value generating
alarms in intervals of up to 1 min. The counter triggers a status bit when it reaches 0x00
and asserts an interrupt if enabled.
The alarm timer is part of the RTC power domain and can be battery powered.
7.22 System control
7.22.1 Configuration registers (CREG)
The following settings are controlled in the configuration register block:
• BOD trip settings
• Oscillator output
• DMA-to-peripheral muxing
• Ethernet mode
• Memory mapping
• Timer/USART inputs
• Enabling the USB controllers
In addition, the CREG block contains the part identification and part configuration
information.
7.22.2 System Control Unit (SCU)
The system control unit determines the function and electrical mode of the digital pins. By
default function 0 is selected for all pins with pull-up enabled. For pins that support a
digital and analog function, the ADC function select registers in the SCU enable the
analog function.
A separate set of analog I/Os for the ADCs and the DAC as well as most USB pins are
located on separate pads and are not controlled through the SCU.
In addition, the clock delay register for the SDRAM EMC_CLK pins and the registers that
select the pin interrupts are located in the SCU.
7.22.3 Clock Generation Unit (CGU)
The Clock Generator Unit (CGU) generates several base clocks. The base clocks can be
unrelated in frequency and phase and can have different clock sources within the CGU.
One CGU base clock is routed to the CLKOUT pins. The base clock that generates the
CPU clock is referred to as CCLK.
Multiple branch clocks are derived from each base clock. The branch clocks offer flexible
control for power-management purposes. All branch clocks are outputs of one of two
Clock Control Units (CCUs) and can be controlled independently. Branch clocks derived
from the same base clock are synchronous in frequency and phase. LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
7.22.4 Internal RC oscillator (IRC)
The IRC is used as the clock source for the WWDT and/or as the clock that drives the
PLLs and the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1.5 %
accuracy over the entire voltage and temperature range.
Upon power-up or any chip reset, the LPC4350/30/20/10 use the IRC as the clock source.
The boot loader then configures the PLL1 to provide a 96 MHz clock for the core and the
PLL0USB or PLL0AUDIO as needed if an external boot source is selected.
7.22.5 PLL0USB (for USB0)
PLL0 is a dedicated PLL for the USB0 High-speed controller.
PLL0 accepts an input clock frequency from an external oscillator in the range of 14 kHz
to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The CCO operates in the range of 4.3 MHz to 550 MHz.
7.22.6 PLL0AUDIO (for audio)
The audio PLL PLL0AUDIO is a general-purpose PLL with a small step size. This PLL
accepts an input clock frequency derived from an external oscillator or internal IRC. The
input frequency is multiplied up to a high frequency with a Current Controlled Oscillator
(CCO). A sigma-delta converter modulates the PLL divider ratios to obtain the desired
output frequency. The output frequency can be set as a multiple of the sampling frequency
fs to 32fs, 64fs, 128 fs, 256 fs, 384 fs, 512 fs and the sampling frequency fs can
range from 16 kHz to 192 kHz (16, 22.05, 32, 44.1, 48, 96,192) kHz. Many other
frequencies are possible as well using the integrated fractional divider.
7.22.7 System PLL1
The PLL1 accepts an input clock frequency from an external oscillator in the range of
1 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current
Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO
operates in the range of 156 MHz to 320 MHz. This range is possible through an
additional divider in the loop to keep the CCO within its frequency range while the PLL is
providing the desired output frequency. The output divider can be set to divide by 2, 4, 8,
or 16 to produce the output clock. Since the minimum output divider value is 2, it is
insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed
following a chip reset. After reset, software can enable the PLL. The program must
configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a
clock source. The PLL settling time is 100 s.
7.22.8 Reset Generation Unit (RGU)
The RGU allows generation of independent reset signals for individual blocks and
peripherals on the LPC4350/30/20/10.
7.22.9 Power control
The LPC4350/30/20/10 feature several independent power domains to control power to
the core and the peripherals (see Figure 9). The RTC and its associated peripherals (the
alarm timer, the CREG block, the OTP controller, the back-up registers, and the event
router) are located in the RTC power-domain. The main regulator or a battery supply can
power the RTC. A power selector switch ensures that the RTC block is always powered
on.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
Active mode and sleep mode apply to the state of the core. In a dual-core system, either
core can be in active or sleep mode independently of the other core.
If the core is in Active mode, it is fully operational and can access peripherals and
memories as configured by software. If the core is in Sleep mode, it receives no clocks,
but peripherals and memories remain running.
Either core can enter sleep mode from active mode independently of the other core and
while the other core remains in active mode or is in sleep mode.
Power-down modes apply to the entire system. In the Power-down modes, both cores and
all peripherals except for peripherals in the always-on power domain are shut down.
Memories can remain powered for retaining memory contents as defined by the individual
power-down mode.
Either core in active mode can put the part into one of the three power down modes if the
core is enabled to do so. If both cores are enabled for putting the system into power-down,
then the system enters power-down only once both cores have received a WFI or WFE
instruction.
Wake-up from sleep mode is caused by an interrupt or event in the core’s NVIC. The
interrupt is captured in the NVIC and an event is captured in the Event router. Both cores
can wake up from sleep mode independently of each other.
Wake-up from the Power-down modes, Deep-sleep, Power-down, and Deep power-down,
is caused by an event on the WAKEUP pins or an event from the RTC or alarm timer.
When waking up from Deep power-down mode, the part resets and attempts to boot.
7.23 Serial Wire Debug/JTAG
Debug and trace functions are integrated into the ARM Cortex-M4. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M4 is configured to support up to eight breakpoints and four
watch points.
Remark: Serial Wire Debug is supported for the ARM Cortex-M4 only,
The ARM Cortex-M0 coprocessor supports JTAG debug. A standard ARM
Cortex-compliant debugger can debug the ARM Cortex-M4 and the ARM Cortex-M0
cores separately or both cores simultaneously.
Remark: In order to debug the ARM Cortex-M0, release the M0 reset by software in the
RGU block.LPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

9. Thermal characteristics
The average chip junction temperature, Tj (C), can be calculated using the following
equation:
(1)
• Tamb = ambient temperature (C),
• Rth(j-a) = the package junction-to-ambient thermal resistance (C/W)
• PD = sum of internal and I/O power dissipation
The internal power dissipation is the product of IDD and VDD. The I/O power dissipation of
the I/O pins is often small and many times can be negligible. However it can be significant
in some applications.

12. ADC/DAC electrical characteristics
[1] The ADC is monotonic, there are no missing codes.
[2] The differential linearity error (ED) is the difference between the actual step width and the ideal step width. See Figure 40.
[3] The integral non-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 40.
[4] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 40.
[5] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See Figure 40.
[6] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
ADC and the ideal transfer curve. See Figure 40.

13.2 Crystal oscillator
The crystal oscillator is controlled by the XTAL_OSC_CTRL register in the CGU (see
LPC43xx user manual).
The crystal oscillator operates at frequencies of 1 MHz to 25 MHz. This frequency can be
boosted to a higher frequency, up to the maximum CPU operating frequency, by the PLL.
The oscillator can operate in one of two modes: slave mode and oscillation mode.
• In slave mode, couple the input clock signal with a capacitor of 100 pF (CC in
Figure 42), with an amplitude of at least 200 mV (RMS). The XTAL2 pin in this
configuration can be left unconnected.
• External components and models used in oscillation mode are shown in Figure 43,
and in Table 39 and Table 40. Since the feedback resistance is integrated on chip,
only a crystal and the capacitances CX1 and CX2 need to be connected externally in
case of fundamental mode oscillation L, CL and RS represent the fundamental
frequency). The capacitance CP in Figure 43 represents the parallel package
capacitance and must not be larger than 7 pF. Parameters FC, CL, RS and CP are
supplied by the crystal manufacturer.

13.3 RTC oscillator
In the RTC oscillator circuit, only the crystal (XTAL) and the capacitances CRTCX1 and
CRTCX2 need to be connected externally. Typical capacitance values for CRTCX1 and
CRTCX2 are CRTCX1/2 = 20 (typical) 4 pF.
An external clock can be connected to RTCX1 if RTCX2 is left open. The recommended
amplitude of the clock signal is Vi(RMS) = 100 mV to 200 mV with a coupling capacitance of
5 pF to 10 pF. Vi(RMS) must be lower than 450 mV. See Figure 42 for a similar slave-mode
set-up that uses the crystal oscillator.
13.4 XTAL and RTCX Printed Circuit Board (PCB) layout guidelines
Connect the crystal on the PCB as close as possible to the oscillator input and output pins
of the chip. Take care that the load capacitors Cx1, Cx2, and Cx3 in case of third overtone
crystal usage have a common ground plane. Also connect the external components to the
ground plain. To keep the noise coupled in via the PCB as small as possible, make loops
and parasitics as small as possible. Choose smaller values of Cx1 and Cx2 if parasitics
increase in the PCB layout.
Ensure that no high-speed or high-drive signals are near the RTCX1/2 signals.
13.5 Standard I/O pin configuration
Figure 45 shows the possible pin modes for standard I/O pins with analog input function:
• Digital output driver enabled/disabled
• Digital input: Pull-up enabled/disabled
• Digital input: Pull-down enabled/disabled
• Digital input: Repeater mode enabled/disabled
• Digital input: Input buffer enabled/disabled
• Analog input
The default configuration for standard I/O pins is input buffer disabled and pull-up
enabled. The weak MOS devices provide a drive capability equivalent to pull-up and
pull-down resistors.

NXP Semiconductors LPC4350/30/20/10
32-bit ARM Cortex-M4/M0 microcontroller
On the LPC4350/30/20/10, USBn_VBUS pins are 5 V tolerant only when VDDIO is
applied and at operating voltage level. Therefore, if the USBn_VBUS function is
connected to the USB connector and the device is self-powered, the USBn_VBUS pins
must be protected for situations when VDDIO = 0 V.
If VDDIO is always at operating level while VBUS = 5 V, the USBn_VBUS pin can be
connected directly to the VBUS pin on the USB connector.
For systems where VDDIO can be 0 V and VBUS is directly applied to the USBn_VBUS
pins, precautions must be taken to reduce the voltage to below 3.6 V, which is the
maximum allowable voltage on the USBn_VBUS pins in this case.
One method is to use a voltage divider to connect the USBn_VBUS pins to VBUS on the
USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be
greater than 0.7VDDIO to indicate a logic HIGH while below the 3.6 V allowable maximum
voltage.
For the following operating conditions
VBUSmax = 5.25 V
VDDIO = 3.6 V,
the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.
For bus-powered devices, a regulator powered by USB can provide 3.3 V to VDDIO
whenever bus power is present and ensure that power to the USBn_VBUS pins is always
present when the 5 V VBUS signal is applied. See Figure 48.
Remark: Applying 5 V to the USBn_VBUS pins for a short time while the regulator ramps
up might compromise the long-term reliability of the part but does not affect its function.

Remark: If the VBUS function of the USB1 interface is not connected, configure the pin
function for GPIO using the function control bits in the SYSCON block.
Remark: In OTG mode, it is important to be able to detect the VBUS level and to charge
and discharge VBUS. This requires adding active devices that disconnect the link when
VDDIO is not present.

1. Introduction
This data sheet describes the functionality of the CLRC632 Integrated Circuit (IC). It
includes the functional and electrical specifications and from a system and hardware
viewpoint gives detailed information on how to design-in the device.
Remark: The CLRC632 supports all variants of the MIFARE Mini, MIFARE 1K,
MIFARE 4K and MIFARE Ultralight RF identification protocols. To aid readability
throughout this data sheet, the MIFARE Mini, MIFARE 1K, MIFARE 4K and
MIFARE Ultralight products and protocols have the generic name MIFARE.
2. General description
The CLRC632 is a highly integrated reader IC for contactless communication at
13.56 MHz. The CLRC632 reader IC provides:
• outstanding modulation and demodulation for passive contactless communication
• a wide range of methods and protocols
• a small, fully integrated package
• pin compatibility with the MFRC500, MFRC530, MFRC531 and SLRC400
All protocol layers of the ISO/IEC 14443 A and ISO/IEC 14443 B communication
standards are supported provided:
• additional components, such as the oscillator, power supply, coil etc. are correctly
applied.
• standardized protocols, such as ISO/IEC 14443-4 and/or ISO/IEC 14443 B
anticollision are correctly implemented
The CLRC632 supports contactless communication using MIFARE higher baud rates (see
Section 9.12 on page 40). The receiver module provides a robust and efficient
demodulation/decoding circuitry implementation for compatible transponder signals (see
Section 9.10 on page 34).
The digital module, manages the complete ISO/IEC 14443 standard framing and error
detection (parity and CRC). In addition, it supports the fast MIFARE security algorithm for
authenticating the MIFARE products (see Section 9.14 on page 42).
All layers of the I-CODE1 and ISO/IEC 15693 protocols are supported by the CLRC632.
The receiver module provides a robust and efficient demodulation/decoding circuitry
implementation for I-CODE1 and ISO/IEC 15693 compatible transponder signals. The
digital module handles I-CODE1 and ISO/IEC 15693 framing and error detection (CRC).

9. Functional description
9.1 Digital interface
9.1.1 Overview of supported microprocessor interfaces
The CLRC632 supports direct interfacing to various 8-bit microprocessors. Alternatively,
the CLRC632 can be connected to a PC’s Enhanced Parallel Port (EPP). Table 4 shows
the parallel interface signals supported by the CLRC632.
9.1.2 Automatic microprocessor interface detection
After a Power-On or Hard reset, the CLRC632 resets parallel microprocessor interface
mode and detects the microprocessor interface type.
The CLRC632 identifies the microprocessor interface using the logic levels on the control
pins. This is performed using a combination of fixed pin connections and the dedicated
Initialization routine (see Section 9.7.4 on page 30).

9.1.3.3 Common read and write strobe: EPP with handshake
Refer to Section 13.4.3 on page 104 for timing specification.
Remark: In the EPP standard a chip select signal is not defined. To cover this situation,
the status of the NCS pin can be used to inhibit the nDStrb signal. If this inhibitor is not
used, it is mandatory that pin NCS is connected to pin DVSS.
Remark: After each Power-On or Hard reset, the nWait signal on pin A0 is
high-impedance. nWait is defined as the first negative edge applied to the nAStrb pin after
the reset phase. The CLRC632 does not support Read Address Cycle.
9.1.4 Serial Peripheral Interface
The CLRC632 provides compatibility with the 5-wire Serial Peripheral Interface (SPI)
standard and acts as a slave during the SPI communication. The SPI clock signal SCK
must be generated by the master. Data communication from the master to the slave uses
the MOSI line. The MISO line sends data from the CLRC632 to the master.

Figure 6 shows the microprocessor connection to the CLRC632 using SPI.
Remark: The SPI implementation for CLRC632 conforms to the SPI standard and
ensures that the CLRC632 can only be addressed as a slave.
9.1.4.1 SPI read data
The structure shown in Table 7 must be used to read data using SPI. It is possible to read
up to n-data bytes. The first byte sent defines both, the mode and the address.
The address byte must meet the following criteria:
• the Most Significant Bit (MSB) of the first byte sets the mode. To read data from the
CLRC632 the MSB is set to logic 1
• bits [6:1] define the address
• the Least Significant Bit (LSB) should be set to logic 0.
As shown in Table 8, all the bits of the last byte sent are set to logic 0.

The source resistance of the p-channel
driver transistors of pin TX1 and TX2 can be
adjusted using the value GsCfgCW[5:0] in
the CwConductance register (see
Section 9.9.3 on page 32). The mean value
of the maximum adjustable source
resistance for pins TX1 and TX2 is stored
as an integer value in in this byte. Typical
values for RsMaxP are between 60 to
140 . This value is denoted as maximum
adjustable source resistance RS(ref)maxP and
is measured by setting the CwConductance
register’s GsCfgCW[5:0] bits to 01h.

9.2.2.3 Register initialization file (read/write)
The EEPROM memory content from block address 3 to 7 can initialize register sub
addresses 10h to 2Fh when the LoadConfig command is executed (see Section 11.5.1 on
page 95). This command requires the EEPROM starting byte address as a two byte
argument for the initialization procedure.
The byte assignment is shown in Table 16.
The register initialization file is large enough to hold values for two initialization sets and
up to one block (16-byte) of user data. The startup configuration could be adapted to the
I-CODE1 StartUp configuration and stored in register block address 3 and 4, providing
additional flexibility.
Remark: The register initialization file can be read/written by users and these bytes can
be used to store other user data.
After each power-up, the default configuration enables the MIFARE and ISO/IEC 14443 A
protocol.

9.2.3 Crypto1 keys (write only)
MIFARE security requires specific cryptographic keys to encrypt data stream
communication on the contactless interface. These keys are called Crypto1 keys.
9.2.3.1 Key format
Keys stored in the EEPROM are written in a specific format. Each key byte must be split
into lower four bits k0 to k3 (lower nibble) and the higher four bits k4 to k7 (higher nibble).
Each nibble is stored twice in one byte and one of the two nibbles is bit-wise inverted. This
format is a precondition for successful execution of the LoadKeyE2 (see Section 11.7.1 on
page 97) and LoadKey commands (see Section 11.7.2 on page 97).
Using this format, 12 bytes of EEPROM memory are needed to store a 6-byte key. This is
shown in Figure 7.
Example: The value for the key must be written to the EEPROM.
• If the key was: A0h A1h A2h A3h A4h A5h then
• 5Ah F0h 5Ah E1h 5Ah D2h 5Ah C3h 5Ah B4h 5Ah A5h would be written.
Remark: It is possible to load data for other key formats into the EEPROM key storage
location. However, it is not possible to validate card authentication with data which will
cause the LoadKeyE2 command (see Section 11.7.1 on page 97) to fail.
9.2.3.2 Storage of keys in the EEPROM
The CLRC632 reserves 384 bytes of memory in the EEPROM for the Crypto1 keys. No
memory segmentation is used to mirror the 12-byte structure of key storage. Thus, every
byte of the dedicated memory area can be the start of a key.
Example: If the key loading cycle starts at the last byte address of an EEPROM block, (for
example, key byte 0 is stored at 12Fh), the next bytes are stored in the next EEPROM
block, for example, key byte 1 is stored at 130h, byte 2 at 131h up to byte 11 at 13Ah.
Based on the 384 bytes of memory and a single key needing 12 bytes, then up to 32
different keys can be stored in the EEPROM.
Remark: It is not possible to load a key exceeding the EEPROM byte location 1FFh.

9.3 FIFO buffer
An 8 64 bit FIFO buffer is used in the CLRC632 to act as a parallel-to-parallel converter.
It buffers both the input and output data streams between the microprocessor and the
internal circuitry of the CLRC632. This makes it possible to manage data streams up to 64
bytes long without needing to take timing constraints into account.
9.3.1 Accessing the FIFO buffer
9.3.1.1 Access rules
The FIFO buffer input and output data bus is connected to the FIFOData register. Writing
to this register stores one byte in the FIFO buffer and increments the FIFO buffer write
pointer. Reading from this register shows the FIFO buffer contents stored at the FIFO
buffer read pointer and increments the FIFO buffer read pointer. The distance between the
write and read pointer can be obtained by reading the FIFOLength register.
When the microprocessor starts a command, the CLRC632 can still access the FIFO
buffer while the command is running. Only one FIFO buffer has been implemented which
is used for input and output. Therefore, the microprocessor must ensure that there are no
inadvertent FIFO buffer accesses. Table 18 gives an overview of FIFO buffer access
during command processing.
9.3.2 Controlling the FIFO buffer
In addition to writing to and reading from the FIFO buffer, the FIFO buffer pointers can be
reset using the FlushFIFO bit. This changes the FIFOLength[6:0] value to zero, bit
FIFOOvfl is cleared and the stored bytes are no longer accessible. This enables the FIFO
buffer to be written with another 64 bytes of data.

9.3.3 FIFO buffer status information
The microprocessor can get the following FIFO buffer status data:
• the number of bytes stored in the FIFO buffer: bits FIFOLength[6:0]
• the FIFO buffer full warning: bit HiAlert
• the FIFO buffer empty warning: bit LoAlert
• the FIFO buffer overflow warning: bit FIFOOvfl.
Remark: Setting the FlushFIFO bit clears the FIFOOvfl bit.
The CLRC632 can generate an interrupt signal when:
• bit LoAlertIRq is set to logic 1 and bit LoAlert = logic 1, pin IRQ is activated.
• bit HiAlertIRq is set to logic 1 and bit HiAlert = logic 1, pin IRQ activated.
The HiAlert flag bit is set to logic 1 only when the WaterLevel[5:0] bits or less can be
stored in the FIFO buffer. The trigger is generated by Equation 1:
(1)
The LoAlert flag bit is set to logic 1 when the FIFOLevel register’s WaterLevel[5:0] bits or
less are stored in the FIFO buffer. The trigger is generated by Equation 2:
(2)
9.3.4 FIFO buffer registers and flags
Table 18 shows the related FIFO buffer flags in alphabetic order.
9.4 Interrupt request system
The CLRC632 indicates interrupt events by setting the PrimaryStatus register bit IRq (see
Section 10.5.1.4 “PrimaryStatus register” on page 51) and activating pin IRQ. The signal
on pin IRQ can be used to interrupt the microprocessor using its interrupt handling
capabilities ensuring efficient microprocessor software.

9.4.1 Interrupt sources overview
Table 20 shows the integrated interrupt flags, related source and setting condition. The
interrupt TimerIRq flag bit indicates an interrupt set by the timer unit. Bit TimerIRq is set
when the timer decrements from one down to zero (bit TAutoRestart disabled) or from one
to the TReLoadValue[7:0] with bit TAutoRestart enabled.
Bit TxIRq indicates interrupts from different sources and is set as follows:
• the transmitter automatically sets the bit TxIRq interrupt when it is active and its state
changes from sending data to transmitting the end of frame pattern
• the CRC coprocessor sets the bit TxIRq after all data from the FIFO buffer has been
processed indicated by bit CRCReady = logic 1
• when EEPROM programming is finished, the bit TxIRq is set and is indicated by bit
E2Ready = logic 1
The RxIRq flag bit indicates an interrupt when the end of the received data is detected.
The IdleIRq flag bit is set when a command finishes and the content of the Command
register changes to Idle.
When the FIFO buffer reaches the HIGH-level indicated by the WaterLevel[5:0] value (see
Section 9.3.3 on page 20) and bit HiAlert = logic 1, then the HiAlertIRq flag bit is set to
logic 1.
When the FIFO buffer reaches the LOW-level indicated by the WaterLevel[5:0] value (see
Section 9.3.3 on page 20) and bit LoAlert = logic 1, then LoAlertIRq flag bit is set to
logic 1.
9.4.2 Interrupt request handling
9.4.2.1 Controlling interrupts and getting their status
The CLRC632 informs the microprocessor about the interrupt request source by setting
the relevant bit in the InterruptRq register. The relevance of each interrupt request bit as
source for an interrupt can be masked by the InterruptEn register interrupt enable bits.

Standard multi-protocol reader solution
If any interrupt request flag is set to logic 1 (showing that an interrupt request is pending)
and the corresponding interrupt enable flag is set, the PrimaryStatus register IRq flag bit is
set to logic 1. Different interrupt sources can activate simultaneously because all interrupt
request bits are OR’ed, coupled to the IRq flag and then forwarded to pin IRQ.
9.4.2.2 Accessing the interrupt registers
The interrupt request bits are automatically set by the CLRC632’s internal state machines.
In addition, the microprocessor can also set or clear the interrupt request bits as required.
A special implementation of the InterruptRq and InterruptEn registers enables changing
an individual bit status without influencing any other bits. If an interrupt register is set to
logic 1, bit SetIxx and the specific bit must both be set to logic 1 at the same time. Vice
versa, if a specific interrupt flag is cleared, zero must be written to the SetIxx and the
interrupt register address must be set to logic 1 at the same time.
If a content bit is not changed during the setting or clearing phase, zero must be written to
the specific bit location.
Example: Writing 3Fh to the InterruptRq register clears all bits. SetIRq is set to logic 0
while all other bits are set to logic 1. Writing 81h to the InterruptRq register sets LoAlertIRq
to logic 1 and leaves all other bits unchanged.
9.4.3 Configuration of pin IRQ
The logic level of the IRq flag bit is visible on pin IRQ. The signal on pin IRQ can also be
controlled using the following IRQPinConfig register bits.
• bit IRQInv: the signal on pin IRQ is equal to the logic level of bit IRq when this bit is set
to logic 0. When set to logic 1, the signal on pin IRQ is inverted with respect to bit IRq.
• bit IRQPushPull: when set to logic 1, pin IRQ has CMOS output characteristics. When
it is set to logic 0, it is an open-drain output which requires an external resistor to
achieve a HIGH-level at pin IRQ.
Remark: During the reset phase (see Section 9.7.2 on page 29) bit IRQInv is set to
logic 1 and bit IRQPushPull is set to logic 0. This results in a high-impedance on pin IRQ.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

9.5 Timer unit
The timer derives its clock from the 13.56 MHz on-board chip clock. The microprocessor
can use this timer to manage timing-relevant tasks.
The timer unit may be used in one of the following configurations:
• Timeout counter
• WatchDog counter
• Stopwatch
• Programmable one shot
• Periodical trigger
The timer unit can be used to measure the time interval between two events or to indicate
that a specific timed event occurred. The timer is triggered by events but does not
influence any event (e.g. a time-out during data receiving does not automatically influence
the receiving process). Several timer related flags can be set and these flags can be used
to generate an interrupt.

9.5.1 Timer unit implementation
9.5.1.1 Timer unit block diagram
Figure 8 shows the block diagram of the timer module.
The timer unit is designed, so that events when combined with enabling flags start or stop
the counter. For example, setting bit TStartTxBegin = logic 1 enables control of received
data with the timer unit. In addition, the first received bit is indicated by the TxBegin event.
This combination starts the counter at the defined TReloadValue[7:0].
The timer stops automatically when the counter value is equal to zero or if a defined stop
event happens.
9.5.1.2 Controlling the timer unit
The main part of the timer unit is a down-counter. As long as the down-counter value is
not zero, it decrements its value with each timer clock cycle.
If the TAutoRestart flag is enabled, the timer does not decrement down to zero. On
reaching value 1, the timer reloads the next clock function with the TReloadValue[7:0].

The timer is started immediately by loading a value from the TimerReload register into the
counter module.
This is activated by one of the following events:
• transmission of the first bit to the card (TxBegin event) with bit TStartTxBegin = logic 1
• transmission of the last bit to the card (TxEnd event) with bit TStartTxEnd = logic 1
• bit TStartNow is set to logic 1 by the microprocessor
Remark: Every start event reloads the timer from the TimerReload register. Thus, the
timer unit is re-triggered.
The timer can be configured to stop on one of the following events:
• receipt of the first valid bit from the card (RxBegin event) with bit
TStopRxBegin = logic 1
• receipt of the last bit from the card (RxEnd event) with bit TStopRxEnd = logic 1
• the counter module has decremented down to zero and bit TAutoRestart = logic 0
• bit TStopNow is set to logic 1 by the microprocessor.
Loading a new value, e.g. zero, into the TimerReload register or changing the timer unit
while it is counting will not immediately influence the counter. In both cases, this is
because this register only affects the counter content after a start event.
If the counter is stopped when bit TStopNow is set, no TimerIRq is flagged.
9.5.1.3 Timer unit clock and period
The timer unit clock is derived from the 13.56 MHz on-board chip clock using the
programmable divider. Clock selection is made using the TimerClock register
TPreScaler[4:0] bits based on Equation 3:
(3)
The values for the TPreScaler[4:0] bits are between 0 and 21 which results in a minimum
periodic time (TTimerClock) of between 74 ns and 150 ms.
The time period elapsed since the last start event is calculated using Equation 4:
(4)
This results in a minimum time period (tTimer) of between 74 ns and 40 s.
9.5.1.4 Timer unit status
The SecondaryStatus register’s TRunning bit shows the timer’s status. Configured start
events start the timer at the TReloadValue[7:0] and changes the status flag TRunning to
logic 1. Conversely, configured stop events stop the timer and sets the TRunning status
flag to logic 0. As long as status flag TRunning is set to logic 1, the TimerValue register
changes on the next timer unit clock cycle.
The TimerValue[7:0] bits can be read directly from the TimerValue register.

9.5.1.5 TimeSlotPeriod
When sending I-CODE1 Quit frames, it is necessary to generate the exact chronological
relationship to the start of the command frame.
If at the end of command execution TimeSlotPeriod > 0, the TimeSlotPeriod starts. If the
FIFO buffer contains data when the end of TimeSlotPeriod is reached, the data is sent. If
the FIFO buffer is empty nothing happens. As long as the TimeSlotPeriod is > 0, the
TimeSlotPeriod counter automatically starts on reaching the end.
This forms the exact time relationship between the start and finish of the command frame
used to generate and send I-CODE1 Quit frames.
When the TimeSlotPeriod > 0, the next Frame starts with exactly the same interval
TimeSlotPeriod/CoderRate delayed after each previous send frame. CoderRate defines
the clock frequency of the encoder. If TimeSlotPeriod[7:0] = 0, the send function is not
automatically triggered.
The content of the TimeSlotPeriod register can be changed while it is running but the
change is only effective after the next TimeSlotPeriod restart.
Example:
• CoderRate = 0 0.5 (~52.97 kHz)
• The interval should be 8.458 ms for I-CODE1 standard mode
Remark: The TimeSlotPeriodMSB bit is contained in the MFOUTSelect register.
Remark: Set bit TxCRCEn to logic 0 before the Quit frame is sent. If TxCRCEn is not set
to logic 0, the Quit frame is sent with a calculated CRC value. Use the CRC8 algorithm to
calculate the Quit value.

9.5.2.1 Time-out and WatchDog counters
After starting the timer using TReloadValue[7:0], the timer unit decrements the TimerValue
register beginning with a given start event. If a given stop event occurs, such as a bit
being received from the card, the timer unit stops without generating an interrupt.
If a stop event does not occur, such as the card not answering within the expected time,
the timer unit decrements down to zero and generates a timer interrupt request. This
signals to the microprocessor the expected event has not occurred within the given time
(tTimer).
9.5.2.2 Stopwatch
The time (tTimer) between a start and stop event is measured by the microprocessor using
the timer unit. Setting the TReloadValue register triggers the timer which in turn, starts to
decrement. If the defined stop event occurs, the timer stops. The time between start and
stop is calculated by the microprocessor using Equation 5, when the timer does not
decrement down to zero.
(5)
9.5.2.3 Programmable one shot timer and periodic trigger
Programmable one shot timer: The microprocessor starts the timer unit and waits for
the timer interrupt. The interrupt occurs after the time specified by tTimer.
Periodic trigger: If the microprocessor sets the TAutoRestart bit, it generates an interrupt
request after every tTimer cycle.

9.6 Power reduction modes
9.6.1 Hard power-down
Hard power-down is enabled when pin RSTPD is HIGH. This turns off all internal current
sinks including the oscillator. All digital input buffers are separated from the input pads and
defined internally (except pin RSTPD itself). The output pins are frozen at a given value.
The status of all pins during a hard power-down is shown in Table 25.
9.6.2 Soft power-down mode
Soft power-down mode is entered immediately using the Control register bit PowerDown.
All internal current sinks, including the oscillator buffer, are switched off. The digital input
buffers are not separated from the input pads and keep their functionality. In addition, the
digital output pins do not change their state.
After resetting the Control register bit PowerDown, the bit indicating Soft power-down
mode is only cleared after 512 clock cycles. Resetting it does not immediately clear it. The
PowerDown bit is automatically cleared when the Soft power-down mode is exited.
Remark: When the internal oscillator is used, time (tosc) is required for the oscillator to
become stable. This is because the internal oscillator is supplied by VDDA and any clock
cycles will not be detected by the internal logic until VDDA is stable.

9.6.3 Standby mode
The Standby mode is immediately entered when the Control register StandBy bit is set. All
internal current sinks, including the internal digital clock buffer are switched off. However,
the oscillator buffer is not switched off.
The digital input buffers are not separated by the input pads, keeping their functionality
and the digital output pins do not change their state. In addition, the oscillator does not
need time to wake-up.
After resetting the Control register StandBy bit, it takes four clock cycles on pin OSCIN for
Standby mode to exit. Resetting bit StandBy does not immediately clear it. It is
automatically cleared when the Standby mode is exited.
9.6.4 Automatic receiver power-down
It is a power saving feature to switch off the receiver circuit when it is not needed. Setting
bit RxAutoPD = logic 1, automatically powers down the receiver when it is not in use.
Setting bit RxAutoPD = logic 0, keeps the receiver continuously powered up.
9.7 StartUp phase
The events executed during the StartUp phase are shown in Figure 10.
9.7.1 Hard power-down phase
The hard power-down phase is active during the following cases:
• a Power-On Reset (POR) caused by power-up on pins DVDD or AVDD activated
when VDDD or VDDA is below the digital reset threshold.
• a HIGH-level on pin RSTPD which is active while pin RSTPD is HIGH. The HIGH level
period on pin RSTPD must be at least 100 s (tPD 100 s). Shorter phases will not
necessarily result in the reset phase (treset). The rising or falling edge slew rate on pin
RSTPD is not critical because pin RSTPD is a Schmitt trigger input.
9.7.2 Reset phase
The reset phase automatically follows the Hard power-down. Once the oscillator is
running stably, the reset phase takes 512 clock cycles. During the reset phase, some
register bits are preset by hardware. The respective reset values are given in the
description of each register (see Section 10.5 on page 50).
Remark: When the internal oscillator is used, time (tosc) is required for the oscillator to
become stable. This is because the internal oscillator is supplied by VDDA and any clock
cycles will not be detected by the internal logic until VDDA is stable.

9.7.3 Initialization phase
The initialization phase automatically follows the reset phase and takes 128 clock cycles.
During the initializing phase the content of the EEPROM blocks 1 and 2 is copied into the
register subaddresses 10h to 2Fh (see Section 9.2.2 on page 13).
Remark: During the production test, the CLRC632 is initialized with default configuration
values. This reduces the microprocessor’s configuration time to a minimum.
9.7.4 Initializing the parallel interface type
A different initialization sequence is used for each microprocessor. This enables detection
of the correct microprocessor interface type and synchronization of the microprocessor’s
and the CLRC632’s start-up. See Section 9.1.3 on page 8 for detailed information on the
different connections for each microprocessor interface type.
During StartUp phase, the command value is set to 3Fh once the oscillator attains clock
frequency stability at an amplitude of > 90 % of the nominal 13.56 MHz clock frequency. At
the end of the initialization phase, the CLRC632 automatically switches to idle and the
command value changes to 00h.
To ensure correct detection of the microprocessor interface, the following sequence is
executed:
• the Command register is read until the 6-bit register value is 00h. On reading the 00h
value, the internal initialization phase is complete and the CLRC632 is ready to be
controlled
• write 80h to the Page register to initialize the microprocessor interface
• read the Command register. If it returns a value of 00h, the microprocessor interface
was successfully initialized
• write 00h to the Page registers to activate linear addressing mode.
9.8 Oscillator circuit
The clock applied to the CLRC632 acts as a time basis for the synchronous system
encoder and decoder. The stability of the clock frequency is an important factor for correct
operation. To obtain highest performance, clock jitter must be as small as possible. This is
best achieved by using the internal oscillator buffer with the recommended circuitry.

If an external clock source is used, the clock signal must be applied to pin OSCIN. In this
case, be very careful in optimizing clock duty cycle and clock jitter. Ensure the clock
quality has been verified. It must meet the specifications described in Section 13.4.5 on
page 106.
Remark: We do not recommend using an external clock source.
9.9 Transmitter pins TX1 and TX2
The signal on pins TX1 and TX2 is the 13.56 MHz energy carrier modulated by an
envelope signal. It can be used to drive an antenna directly, using minimal passive
components for matching and filtering (see Section 15.1 on page 107). To enable this, the
output circuitry is designed with a very low-impedance source resistance. The TxControl
register is used to control the TX1 and TX2 signals.

9.9.2 Antenna operating distance versus power consumption
Using different antenna matching circuits (by varying the supply voltage on the antenna
driver supply pin TVDD), it is possible to find the trade-off between maximum effective
operating distance and power consumption. Different antenna matching circuits are
described in the Application note “MIFARE Design of MFRC500 Matching Circuit and
Antennas”.
9.9.3 Antenna driver output source resistance
The output source conductance of pins TX1 and TX2 can be adjusted between 1 and
100 using the CwConductance register GsCfgCW[5:0] bits.
The output source conductance of pins TX1 and TX2 during the modulation phase can be
adjusted between 1 and 100 using the ModConductance register GsCfgMod[5:0] bits.
The values are relative to the reference resistance (RS(ref)) which is measured during the
production test and stored in the CLRC632 EEPROM. It can be read from the product
information field (see Section 9.2.1 on page 13). The electrical specification can be found

9.9.3.2 Calculating the relative source resistance
The reference source resistance RS(ref) can be calculated using Equation 6.
(6)
The reference source resistance (RS(ref)) during the modulation phase can be calculated
using ModConductance register’s GsCfgMod[5:0].
9.9.3.3 Calculating the effective source resistance
Wiring resistance (RS(wire)): Wiring and bonding add a constant offset to the driver
resistance that is relevant when pins TX1 and TX2 are switched to low-impedance. The
additional resistance for pin TX1 (RS(wire)TX1) can be set approximately as shown in
Equation 7.
(7)
Effective resistance (RSx): The source resistances of the driver transistors (RsMaxP
byte) read from the Product Information Field (see Section 9.2.1 on page 13) are
measured during the production test with CwConductance register’s
GsCfgCW[5:0] = 01h.
To calculate the driver resistance for a specific value set in GsCfgMod[5:0], use
Equation 8.
(8)
9.9.4 Pulse width
The envelope carries the data signal information that is transmitted to the card. It is an
encoded data signal based on the Miller code. In addition, each pause of the Miller
encoded signal is again encoded as a pulse of a fixed width. The width of the pulse is
adjusted using the ModWidth register. The pulse width (tw) is calculated using Equation 9
where the frequency constant (fclk) = 13.56 MHz.

NXP Semiconductors CLRC632
Standard multi-protocol reader solution
The quadrature demodulator uses two different clocks (Q-clock and I-clock) with a
phase-shift of 90 between them. Both resulting subcarrier signals are amplified, filtered
and forwarded to the correlation circuitry. The correlation results are evaluated, digitized
and then passed to the digital circuitry. Various adjustments can be made to obtain
optimum performance for all processing units.
9.10.1 Receiver circuit block diagram
Figure 12 shows the block diagram of the receiver circuit. The receiving process can be
broken down in to several steps. Quadrature demodulation of the 13.56 MHz carrier signal
is performed. To achieve the optimum performance, automatic Q-clock calibration is
recommended (see Section 9.10.2.1 on page 35).
The demodulated signal is amplified by an adjustable amplifier. A correlation circuit
calculates the degree of similarity between the expected and the received signal. The
BitPhase register enables correlation interval position alignment with the received signal’s
bit grid. In the evaluation and digitizer circuitry, the valid bits are detected and the digital
results are sent to the FIFO buffer. Several tuning steps are possible for this circuit.
The signal can be observed on its way through the receiver as shown in Figure 12. One
signal at a time can be routed to pin AUX using the TestAnaSelect register as described in
Section 15.2.2 on page 112.
9.10.2 Receiver operation
In general, the default settings programmed in the StartUp initialization file are suitable for
use with the CLRC632 to MIFARE card data communication. However, in some
environments specific user settings will achieve better performance.
9.10.2.1 Automatic Q-clock calibration
The quadrature demodulation concept of the receiver generates a phase signal (I-clock)
and a 90 phase-shifted quadrature signal (Q-clock). To achieve the optimum
demodulator performance, the Q-clock and the I-clock must be phase-shifted by 90. After
the reset phase, a calibration procedure is automatically performed.

Automatic calibration can be set-up to execute at the end of each Transceive command if
bit ClkQCalib = logic 0. Setting bit ClkQCalib = logic 1 disables all automatic calibrations
except after the reset sequence. Automatic calibration can also be triggered by the
software when bit ClkQCalib has a logic 0 to logic 1 transition.
Remark: The duration of the automatic Q-clock calibration is 65 oscillator periods or
approximately 4.8 s.
The ClockQControl register’s ClkQDelay[4:0] value is proportional to the phase-shift
between the Q-clock and the I-clock. The ClkQ180Deg status flag bit is set when the
phase-shift between the Q-clock and the I-clock is greater than 180.
Remark:
• The StartUp configuration file enables automatic Q-clock calibration after a reset
• If bit ClkQCalib = logic 1, automatic calibration is not performed. Leaving this bit set to
logic 1 can be used to permanently disable automatic calibration.
• It is possible to write data to the ClkQDelay[4:0] bits using the microprocessor. The
aim could be to disable automatic calibration and set the delay using the software.
Configuring the delay value using the software requires bit ClkQCalib to have been
previously set to logic 1 and a time interval of at least 4.8 s has elapsed. Each delay
value must be written with bit ClkQCalib set to logic 1. If bit ClkQCalib is logic 0, the
configured delay value is overwritten by the next automatic calibration interval.
9.10.2.2 Amplifier
The demodulated signal must be amplified by the variable amplifier to achieve the best
performance. The gain of the amplifiers can be adjusted using the RxControl1 register

9.10.2.3 Correlation circuitry
The correlation circuitry calculates the degree of matching between the received and an
expected signal. The output is a measure of the amplitude of the expected signal in the
received signal. This is done for both, the Q and I-channels. The correlator provides two
outputs for each of the two input channels, resulting in a total of four output signals.
The correlation circuitry needs the phase information for the incoming card signal for
optimum performance. This information is defined for the microprocessor using the
BitPhase register. This value defines the phase relationship between the transmitter and
receiver clock in multiples of the BitPhase time (tBitPhase) = 1 / 13.56 MHz.
9.10.2.4 Evaluation and digitizer circuitry
The correlation results are evaluated for each bit-half of the Manchester coded signal. The
evaluation and digitizer circuit decides from the signal strengths of both bit-halves, if the
current bit is valid
• If the bit is valid, its value is identified
• If the bit is not valid, it is checked to identify if it contains a bit-collision
Select the following levels for optimal using RxThreshold register bits:
• MinLevel[3:0]: defines the minimum signal strength of the stronger bit-halve’s signal
which is considered valid.
• CollLevel[3:0]: defines the minimum signal strength relative to the amplitude of the
stronger half-bit that has to be exceeded by the weaker half-bit of the Manchester
coded signal to generate a bit-collision. If the signal’s strength is below this value,
logic 1 and logic 0 can be determined unequivocally.
After data transmission, the card is not allowed to send its response before a preset time
period which is called the frame guard time in the ISO/IEC 14443 standard. The length of
this time period is set using the RxWait register’s RxWait[7:0] bits. The RxWait register
defines when the receiver is switched on after data transmission to the card in multiples of
one bit duration.
If bit RcvClkSelI is set to logic 1, the I-clock is used to clock the correlator and evaluation
circuits. If bit RcvClkSelI is set to logic 0, the Q-clock is used.
Remark: It is recommended to use the Q-clock.
9.11 Serial signal switch
The CLRC632 comprises two main blocks:
• digital circuitry: comprising the state machines, encoder and decoder logic etc.
• analog circuitry: comprising the modulator, antenna drivers, receiver and
amplification circuitry
The interface between these two blocks can be configured so that the interface signals
are routed to pins MFIN and MFOUT. This makes it possible to connect the analog part of
one CLRC632 to the digital part of another device.
The serial signal switch can be used to measure MIFARE and ISO/IEC 14443 A as well as
related I-CODE1 and ISO/IEC 15693 signals.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.

Manchester signal and the Manchester signal with subcarrier can only be accessed on pin
MFOUT at 106 kBd based on ISO/IEC 14443 A.
9.11.1 Serial signal switch block diagram
Figure 14 shows the serial signal switches. Three different switches are implemented in
the serial signal switch enabling the CLRC632 to be used in different configurations.
The serial signal switch can also be used to check the transmitted and received data
during the design-in phase or for test purposes. Section 15.2.1 on page 110 describes the
analog test signals and measurements at the serial signal switch.
Remark: The SLR400 uses pin name SIGOUT for pin MFOUT. The CLRC632
functionality includes the test modes for the SLRC400 using pin MFOUT.
Section 9.11.2, Section 9.11.2.1 and Section 9.11.2.2 describe the relevant registers and
settings used to configure and control the serial signal switch.
9.11.2 Serial signal switch registers
The RxControl2 register DecoderSource[1:0] bits define the input signal for the internal
Manchester decoder and are described in Table 30.

[1] The number column refers to the value in the number column of Table 30, Table 31 and Table 32.
Two CLRC632 devices configured as described in Table 33 can be connected to each
other using pins MFOUT and MFIN.
Remark: The active antenna concept can only be used at 106 kBd based on
ISO/IEC 14443 A.
9.11.2.2 Driving both RF parts
It is possible to connect both passive and active antennas to a single IC. The passive
antenna pins TX1, TX2 and RX are connected using the appropriate filter and matching
circuit. At the same time an active antenna is connected to pins MFOUT and MFIN. In this
configuration, two RF parts can be driven, one after another, by one microprocessor.
9.12 MIFARE higher baud rates
The MIFARE system is specified with a fixed baud rate of 106 kBd for communication on
the RF interface. The current version of ISO/IEC 14443 A also defines 106 kBd for the
initial phase of a communication between Proximity Integrated Circuit Cards (PICC) and
Proximity Coupling Devices (PCD).
To cover requirements of large data transmissions and to speed up terminal to card
communication, the CLRC632 supports communication at MIFARE higher baud rates in
combination with a microcontroller IC such as the MIFARE ProX.
The MIFARE higher baud rates concept is described in the application note: MIFARE
Implementation of Higher Baud rates Ref. 5. This application covers the integration of the
MIFARE higher baud rates communication concept in current applications.

9.14 MIFARE authentication and Crypto1
The security algorithm used in the MIFARE products is called Crypto1. It is based on a
proprietary stream cipher with a 48-bit key length. To access data on MIFARE cards,
knowledge of the key format is needed. The correct key must be available in the
CLRC632 to enable successful card authentication and access to the card’s data stored in
the EEPROM.
After a card is selected as defined in ISO/IEC 14443 A standard, the user can continue
with the MIFARE protocol. It is mandatory that card authentication is performed.
Crypto1 authentication is a 3-pass authentication which is automatically performed when
the Authent1 and Authent2 commands are executed (see Section 11.7.3 on page 98 and
Section 11.7.4 on page 98).
During the card authentication procedure, the security algorithm is initialized. After a
successful authentication, communication with the MIFARE card is encrypted.
9.14.1 Crypto1 key handling
On execution of the authentication command, the CLRC632 reads the key from the key
buffer. The key is always read from the key buffer and ensures Crypto1 authentication
commands do not require addressing of a key. The user must ensure the correct key is
prepared in the key buffer before triggering card authentication.
The key buffer can be loaded from:
• the EEPROM using the LoadKeyE2 command (see Section 11.7.1 on page 97)
• the microprocessor’s FIFO buffer using the LoadKey command (see Section 11.7.2
on page 97). This is shown in Figure 15.

9.14.2 Authentication procedure
The Crypto1 security algorithm enables authentication of MIFARE cards. To obtain valid
authentication, the correct key has to be available in the key buffer of the CLRC632. This
can be ensured as follows:
1. Load the internal key buffer by using the LoadKeyE2 (see Section 11.7.1 on page 97)
or the LoadKey (see Section 11.7.2 on page 97) commands.
2. Start the Authent1 command (see Section 11.7.3 on page 98). When finished, check
the error flags to obtain the command execution status.
3. Start the Authent2 command (see Section 11.7.4 on page 98). When finished, check
the error flags and bit Crypto1On to obtain the command execution status.
10. CLRC632 registers
10.1 Register addressing modes
Three methods can be used to operate the CLRC632:
• initiating functions and controlling data by executing commands
• configuring the functional operation using a set of configuration bits
• monitoring the state of the CLRC632 by reading status flags
The commands, configuration bits and flags are accessed using the microprocessor
interface. The CLRC632 can internally address 64 registers using six address lines.
10.1.1 Page registers
The CLRC632 register set is segmented into eight pages contain eight registers each. A
Page register can always be addressed, irrespective of which page is currently selected.
10.1.2 Dedicated address bus
When using the CLRC632 with the dedicated address bus, the microprocessor defines
three address lines using address pins A0, A1 and A2. This enables addressing within a
page. To switch between registers in different pages a paging mechanism needs to be
used.
Table 36 shows how the register address is assembled.
10.1.3 Multiplexed address bus
The microprocessor may define all six address lines at once using the CLRC632 with a
multiplexed address bus. In this case either the paging mechanism or linear addressing
can be used.
Table 37 shows how the register address is assembled.

10.2 Register bit behavior
Bits and flags for different registers behave differently, depending on their functions. In
principle, bits with same behavior are grouped in common registers. Table 38 describes
the function of the Access column in the register tables.

Table 38. Behavior and designation of register bits
Abbreviation Behavior Description
R/W read and write These bits can be read and written by the microprocessor.
Since they are only used for control, their content is not
influenced by internal state machines.
Example: TimerReload register may be read and written by
the microprocessor. It will also be read by internal state
machines but never changed by them.
D dynamic These bits can be read and written by the microprocessor.
Nevertheless, they may also be written automatically by
internal state machines.
Example: the Command register changes its value
automatically after the execution of the command.
R read only These registers hold flags which have a value determined by
internal states only.
Example: the ErrorFlag register cannot be written externally
but shows internal states.
W write only These registers are used for control only. They may be written
by the microprocessor but cannot be read. Reading these
registers returns an undefined value.
Example: The TestAnaSelect register is used to determine the
signal on pin AUX however, it is not possible to read its
content.CLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014. All rights reserved.
