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. 6.Vstr 5.N.C. 4.Vfb 3.Vcc 2.GND 1.Drain TO-220F-6L 6.Vstr 5.N.C. 4.Vfb 3.Vcc 2.GND 1.Drain I2-PAK-6L FSDM0565RB 4 Absolute Maximum Ratings (Ta=25°C, unless otherwise specified) Notes: 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). 8V/12V 3 Vref Internal Bias Vcc 6 Vstr Istart Vcc good VDC CVcc 4 OSC Vcc Vref Idelay IFB VSD R 2.5R Gate driver OLP D1 D2 + Vfb* - Vfb KA431 CB Vo H11A817A Rsense SenseFET FSDM0565RB 12 Figure 6. Auto restart operation 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.

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. Figure 8.

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.

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 following peripherals are available on chip: • Master SPI port with five select outputs • Two UARTs with support for hardware or software flow control • Three programmable Timer/Counters – all three support Pulse Width Modulation (PWM) capability, two have capture/compare facility • Two programmable Sleep Timers and a Tick Timer • Two-wire serial interface (compatible with SMbus and I2 C) supporting master and slave operation • Four-wire digital audio interface (compatible with I²S) • Slave SPI port for Intelligent peripheral mode (shared with digital I/O) • Twenty-one digital I/O lines (multiplexed with peripherals such as timers and UARTs) • Four channel, 12-bit, Analogue to Digital converter • Two 12-bit Digital to Analogue converters • Two programmable analogue comparators • Internal temperature sensor and battery monitor • Time Of Flight ranging engine • Two low power pulse counters • Random number generator • Watchdog Timer and Voltage Brown-out • Sample FIFO for digital audio interface or ADC/DAC • JTAG hardware debug port User applications access the peripherals using the Integrated Peripherals API. This allows applications to use a tested and easily understood view of the peripherals allowing rapid system development. 8 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 1.4 Block Diagram 32-bit RISC CPU Reset SPI Master MUX UART0 UART1 Wakeup Timer1 Wakeup Timer0 Security Coprocessor DIO6/TXD0/JTAG_TDO DIO7/RXD0/JTAG_TDI DIO4/CTS0/JTAG_TCK DIO5/RTS0/JTAG_TMS DIO19/TXD1/JTAG_TDO DIO17/CTS1/IP_SEL/DAI_SCK/ JTAG_TCK DIO18/RTS1/IP_INT/DAI_SDOUT/ JTAG_TMS Digital Baseband Radio Programmable Interrupt Controller Timer0 2-wire Interf ace Timer1 SPICLK DIO10/TIM0OUT/32KXTALOUT SPIMOSI SPIMISO SPISEL0 DIO0/SPISEL1 DIO3/SPISEL4/RFTX DIO2/SPISEL3/RFRX DIO1/SPISEL2/PC0 DIO9/TIM0CAP/32KXTALIN/32KIN DIO8/TIM0CK_GT/PC1 DIO13/TIM1OUT/ADE/DAI_SDIN DIO11/TIM1CK_GT/TIM2OUT DIO12/TIM1CAP/ADO/DAI_WS DIO14/SIF_CLK/IP_CLK DIO15/SIF_D/IP_DO DIO16/RXD1/IP_DI/JTAG_TDI From Peripherals RESETN Wireless Transceiv er 32MHz Clock Generator XTAL_IN XTAL_OUT RF_IN VCOTUNE Tick Timer Voltage Regulators 1.8V VDD1 VDD2 Intelligent Peripheral IBAIS VB_XX Clock Divider Multiplier Timer2 SPISEL1 SPISEL2 SPISEL3 SPISEL4 TXD0 RXD0 RTS0 CTS0 TXD1 RXD1 RTS1 CTS1 TIM0CK_GT TIM0CAP TIM0OUT TIM1CK_GT TIM1CAP TIM1OUT TIM2OUT SIF_D SIF_CLK IP_DO IP_DI IP_INT IP_CLK IP_SEL 4-wire Digital Audio Interf ace I2S_OUT I2S_DIN I2S_CLK I2S_SYNC Pulse Counters PC0 PC1 JTAG Debug JTAG_TDI JTAG_TMS JTAG_TCK JTAG_TDO RAM 128kB ROM 128kB OTP eFuse 32kHz RC Osc 32kHz Clock Select 32KIN 32kHz Clock Gen 32KXTALIN 32KXTALOUT Antenna Div ersity ADO ADE Time Of Flight Sample FIFO DIO20/RXD1/JTAG_TDI 24MHz RC Osc Comparator2 COMP2P COMP2M COMP1P/ Comparator1 EXT_PA_C COMP1M/ EXT_PA_B DAC1 DAC2 DAC1 DAC2 ADC M U ADC4 X ADC1 ADC2 ADC3 Temperature Sensor Supply Monitor CPU and 16MHz System Clock Watchdog Timer Brown-out Detect Figure 1: JN5148 Block Diagram DIO 16/IP_DI© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 9 2 Pin Configurations DIO16/RXD 1/IP_DI/JTAG_TDI DIO17/CTS1/IP_SEL/DAI_SC K/JTAG_TCK VSS3 DIO18/RTS1/IP_INT/DAI_SDOUT/JTAG_TMS DIO19/TXD1/JTAG_TDO VSS2 VSSS XTAL_OUT XTAL_IN VB_SYNTH VCOTUNE VB_VCO VDD1 IBIAS VREF VB_RF2 RF_IN VB_RF COMP1M COMP1P ADC1 ADC2 ADC3 ADC4 COMP2M COMP2P VB_A NC DAC1 DAC2 DIO20/RXD 1/JTAG_TDI VSS1 SPICLK SPIMISO VB_RAM SPIMOSI SPISEL0 DIO0/SPISEL1 RESETN VB_DIG DIO1/SPISEL2/PC0 DIO2/SPISEL3/RFRX DIO15/SIF_D/IP_DO DIO14/SIF_C LK/IP_CLK DIO13/T IM1OUT/ADE/DAI_SDIN DIO12/T IM1CAP/ADO/DAI_WS DIO11/T IM1CK_GT /TIM2OUT DIO10/T IM0OUT/32KXT ALOUT DIO9/TIM0CAP/32KXT ALIN/32KIN VDD2 DIO8/TIM0CK_GT/PC 1 DIO7/RXD0/JT AG_TDI DIO6/TXD0/JTAG_TDO DIO5/RTS0/JTAG_TMS DIO4/CTS0/JTAG_TCK DIO3/SPISEL4/RFTX VSSA (Paddl e) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 56 55 54 53 52 51 50 49 48 47 46 45 44 43 Figure 2: 56-pin QFN Configuration (top view)  Note: Please refer to Appendix B.4 JN5148 Module Reference Design for important applications information regarding the connection of the PADDLE to the PCB.

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. VDD1 Analogue I/O Pin VSSA Analogue Peripheral Figure 3: Analogue I/O Cell 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. A schematic view of the digital I/O cell is in Figure 4: DIO Pin Equivalent Schematic.14 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 I O IE VDD2 VSS Pu RPU RPROT OE DIO[x] Pin 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 JN5148 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 4 Memory Organisation This section describes the different memories found within the JN5148. The device contains ROM, RAM, OTP eFuse memory, the wireless transceiver and peripherals all within the same linear address space. 0x00000000 0x00020000 RAM (128kB) 0xF0000000 0xFFFFFFFF Unpopulated ROM (128kB) 0xF0020000 RAM Echo 0x04000000 Peripherals 0x02000000 Figure 5: JN5148 Memory Map 4.1 ROM 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 the handling of interrupts. ROM contents are shown in Figure 6.

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. MAC Data Interrupt Vector Table Application CPU Stack (Grows Down) 0x04000000 0x04020000 MAC Address Figure 7: Typical RAM Contents 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. JN5148 Serial Memory SPISEL0 SPIMISO SPIMOSI SPICLK SS SDO SDI CLK Figure 8: Connecting External Serial Memory18 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 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. Manufacturer Device Number SST (Silicon Storage Technology) 25VF010A (1Mbit device) Numonyx M25P10-A (1Mbit device), M25P40 (4Mbit device) Table 1: Supported Flash Memories 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. XTALOUT C1 C2 R1 XTALIN JN5148 Figure 9: 32MHz Crystal Oscillator Connections 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. 32KXTALIN 32KXTALOUT JN5148 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. RESETN Pin Internal RESET VDD Figure 11: Internal Power-on Reset When the supply drops below the power on reset ‘falling’ threshold, it will re-trigger the reset. Use of the external reset circuit show in Figure 12 is suggested. 22 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 RESETN C1 R1 JN5148 VDD 18k 470nF 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. Internal Reset RESETN pin Reset 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. 8.1 Radio Figure 14 shows the single ended radio architecture. LNA synth PA ADC Reference & Bias Switch Radio Calibration Lim1 Lim2 Lim3 Lim4 sigma delta D-Type 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 L1 R1 43K IBIAS C20 100nF L2 2.7nH VB_RF VREF VB_RF2 RF_IN C12 47pF C3 100nF VB_RF1 C1 47pF L1 5.6nH To Coaxial Socket or Integrated Antenna VB_RF Figure 15 External Radio Components 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 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 Antenna A Antenna B A B COM SEL SELB ADO (DIO[12]) ADE (DIO[13]) Device RF Port RF Switch: Single-Pole, Double-Throw (SPDT) Figure 16 Simple Antenna Diversity Implementation using External RF Switch ADO (DIO[12]) TX Active RX Active ADE (DIO[13]) 1st TX-RX Cycle 2nd TX-RX Cycle (1st Retry) Figure 17 Antenna Diversity ADO Signal for TX with Acknowledgement If two DIO pins cannot be spared, DIO13 can be configured to be a normal DIO pin, and the inverse of ADO generated with an inverter on the PCB. © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 29 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. AGC Demodulation Symbol Detection (Despreading) Modulation Spreading TX RX TX Data Interface RX Data Interface VCO Sigma-Delta Modulator IF Signal Gain Figure 18 Modem Architecture 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. Figure 19 Energy Detect Value vs Receive Power Level30 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 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. Append Checksum Verify Checksum CSMA CCA Backoff Control Deserialiser Serialiser Tx/Rx Frame Buffer Tx Bitstream Rx Bitstream Protocol Timing Engine Supervisor Radio Status Control Processor Bus Protocol Timers Security Coprocessor Decrypt Port Encrypt Port AES Codec Figure 20: 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. Processor Interface AES Block Encrpytion Controller AES Encoder Key Generation Figure 21: Security Coprocessor Architecture 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 4-wire Digital Audio Interface Antenna Diversity JTAG Debug Pulse Counters Intelligent Peripheral MUX 2-wire Interface Timer2 Timer1 Timer0 UART1 UART0 SPI Master SPISEL1 SPISEL2 SPISEL3 SPISEL4 TXD0 RXD0 RTS0 CTS0 TXD1 RXD1 RTS1 CTS1 TIM0CK_GT TIM0OUT TIM0CAP TIM1CK_GT TIM1OUT TIM1CAP TIM2OUT SIF_D SIF_CLK IP_DO IP_DI IP_INT IP_CLK IP_SEL PC0 PC1 JTAG_TDI JTAG_TMS JTAG_TCK JTAG_TDO ADO ADE I2S_OUT I2S_DIN I2S_CLK I2S_SYNC SPICLK SPIMOSI SPIMISO SPISEL0 DIO0/SPISEL1 DIO1/SPISEL2/PC0 DIO2/SPISEL3/RFRX DIO3/SPISEL4/RFTX DIO4/CTS0/JTAG_TCK DIO5/RTS0/JTAG_TMS DIO6/TXD0/JTAG_TDO DIO7/RXD0/JTAG_TDI DIO8/TIM0CK_GT/PC1 DIO9/TIM0CAP/32KXTALIN/32KIN DIO10/TIM0OUT/32KXTALOUT DIO11/TIM1CK_GT/TIM2OUT DIO12/TIM1CAP/ADO/DAI_WS DIO13/TIM1OUT/ADE/DAI_SDN DIO14/SIF_CLK/IP_CLK DIO15/SIF_D/IP_DO DIO16/IP_DI DIO17/CTS1/IP_SEL/DAI_SCK/ JTAG_TCK DIO18/RTS1/IP_INT/DAI_SDOUT/ JTAG_TMS DIO19/TXD1/JTAG_TDO DIO20/RXD1/JTAG_TDI Figure 22 DIO Block Diagram© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 35 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 Clock Divider SPI Bus Cycle Controller Data Buffer DIV Clock Edge Select Data CHAR_LEN LSB SPIMISO SPIMOSI SPICLK Select Latch SPISEL [4..0] 16 MHz 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 C SO SS Slave 0 Flash/ EEPROM Memory JN5148 37 38 41 42 43 36 33 34 SI C SO SS Slave 1 User Defined SI C SO SS Slave 2 User Defined SI C SO SS Slave 3 User Defined SI C SO SS Slave 4 User Defined SPIMISO SPIMOSI SPICLK SPISEL4 SPISEL2 SPISEL3 SPISEL1 SPISEL0 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. SPICLK Mode Description Polarity (CPOL) Phase (CPHA) 0 0 0 SPICLK is low when idle – the first edge is positive. Valid data is output on SPIMOSI before the first clock and changes every negative edge. SPIMISO is sampled every positive edge. 0 1 1 SPICLK is low when idle – the first edge is positive. Valid data is output on SPIMOSI every positive edge. SPIMISO is sampled every negative edge. 1 0 2 SPICLK is high when idle – the first edge is negative. Valid data is output on SPIMOSI before the first clock edge and is changed every positive edge. SPIMISO is sampled every negative edge. 1 1 3 SPICLK is high when idle – the first edge is negative. Valid data is output on SPIMOSI every negative edge. SPIMISO is sampled every positive edge. 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. 0 1 2 3 4 5 6 7 Instruction (0x03) 23 22 21 3 2 1 0 8 9 10 28 29 30 31 24-bit Address MSB Instruction Transaction 7 6 5 4 3 2 1 0 MSB 0 1 2 3 4 5 7 8N-1 3 2 1 0 LSB Read Data Bytes Transaction(s) 1-N SPISEL SPICLK SPIMOSI SPIMISO SPISEL SPICLK SPIMOSI SPIMISO 8 9 10 7 6 5 MSB Byte 1 Byte 2 Byte N value unused by peripherals 6 Figure 25: Example SPI Waveforms – Reading from FLASH device using Mode 038 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 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 Interrupt Generator Rise Fall Delta-Sigma Counter Reset Generator = Prescaler INT Int Enable SYSCLK S/w Reset System Reset Single Shot = S R OE Gate Gate Edge Select Reset PWM/DeltaSigma Capture Generator Capture Enable PWM/∆−Σ PWM/∆−Σ TIMxCK_GT TIMxOUT TIMxCAP Figure 26: Timer Unit Block Diagram© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 39 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 CLK CAPT x 9 3 x 14 t RISE t RISE t FALL t FALL Rise Fall 9 5 3 4 7 Capture Mode Enabled Figure 28: Capture Mode 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 1 2 3 1 2 N Conversion cycle 1 217 N Conversion cycle 2 3 Figure 29: Return To Zero Mode in Operation 1 2 3 1 2 N Conversion cycle 1 N 3 216 Conversion cycle 2 Figure 30: Non-Return to Zero Mode 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.

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 Match Value Counter = Mode Control & & SysClk Run Match Int Enable Tick Timer Interrupt Reset Mode 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 Divisor Latch Registers Line Status Register Line Control Register FIFO Control Register Receiver FIFO Transmitter FIFO Baud Generator Logic Transmitter Shift Register Receiver Shift Register Transmitter Logic Receiver Logic RXD TXD Modem Control Register Modem Status Register Modem Signals Logic RTS CTS Interrupt ID Register Interrupt Enable Register Interrupt Logic Internal Interrupt 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 The following example shows the UART connected to a 9-pin connector compatible with a PC.

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.

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.

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. SIF_CLK SIF_CLK SIF_CLK Master SIF_CLK Slave SIF_CLK Wired-AND SIF_CLK Clock held low by Slave Figure 36: Clock Stretching 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. SIF_CLK1 SIF_CLK2 SIF_CLK Master1 SIF_CLK Master2 SIF_CLK Wired-AND SIF_CLK Start counting low period Start counting high period Wait State Figure 37: Multi-Master Clock Synchronisation 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. Address Name Behaviour 0000 000 General Call/Start Byte Ignored 0000 001 CBUS address Ignored 0000 010 Reserved Ignored 0000 011 Reserved Ignored 0000 1XX Hs-mode master code Ignored 1111 1XX Reserved Ignored 1111 0XX 10-bit address Only responded to if 10 bit address set in address register 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 Data Buffer Right R2 R1 R0 Left L2 L1 L0 SCK WS SD Max Size SD 3-bits MSB LSB MSB LSB Left Right L2 L1 L0 0 R2 R1 R0 MSB-1 MSB-2 MSB-1 MSB-2 0 0 0 Figure 38: I²S Mode Data Buffer Right R2 R1 R0 Left L2 L1 L0 SCK WS SD Max Size SD 3-bits MSB LSB MSB LSB Left Right L2 L1 L0 0 R2 R1 R0 MSB-1 MSB-2 MSB-1 MSB-2 0 0 0 Figure 39: Left Justified Mode Data Buffer Right R2 R1 R0 Left L2 L1 L0 SCK WS SD Max Size SD 3-bits MSB LSB MSB LSB Left Right 0 L2 L1 L0 R2 R1 R0 MSB-1 MSB-1 0 0 0 Figure 40: Right Justified Mode© NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 53 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. JN5148 Intelligent Peripheral Interface SPI MASTER System Processor (e.g. in cellphone, computer) CPU IP_DO SPIMISO IP_INT SPIINT IP_DI SPIMOSI IP_SEL SPISEL IP_CLK SPICLK Figure 41: Intelligent Peripheral Connection 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. IP_SEL IP_CLK IP_DI Status (8-bit) N words of data IP_DO data length or 0s (8-bit) padding (8-bit) Status (8-bit) data length or 0s (8-bit) N words of data padding (8-bit) 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 deasserting IP_SEL.58 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 20 Analogue Peripherals The JN5148 contains a number of analogue peripherals allowing the direct connection of a wide range of external sensors, switches and actuators. ADC DAC1 DAC2 VREF Chip Boundary Internal Reference Processor Bus Supply Voltage (VDD1) Vref select Temp Sensor Comparator 2 Comparator 1 COMP2M COMP1M COMP1P COMP2P DAC1 DAC2 ADC1 ADC2 ADC3 ADC4 Vref 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. VREF Gain Setting Maximum Input Range Supply Voltage Range (VDD) 1.2V 1.6V 1.2V 1.6V 0 0 1 1 1.2V 1.6V 2.4V 3.2V 2.2V - 3.6V 2.2V - 3.6V 2.6V - 3.6V 3.4V - 3.6V 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. ADC pin 5 K 8 pF Sample Switch ADC front end 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 22 Electrical Characteristics 22.1 Maximum Ratings Exceeding these conditions may result in damage to the device.

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 = 1 2 1 2 T T T T 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 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 2 T1× T 2 ×ω m C C g ≥ 2 4         + L S L m C C C R This can be used to give an equation for the required transconductance. 1 2 2 1 2 1 2 2 4 [ ( ) ] T T m S T T T T m C C R C C C C C g × × + + × ≥ 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 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. XTALOUT C1 C2 XTALIN R1 JN5148 Figure 58: Crystal oscillator connections The clock generated by this oscillator provides the reference for most of the JN5148 subsystems, including the transceiver, processor, memory and digital and analogue peripherals. 32MHz Crystal Requirements Parameter Min Typ Max Notes Crystal Frequency 32MHz Crystal Tolerance 40ppm Including temperature and ageing Crystal ESR Range (Rm) 10Ω 60Ω See below for more details Crystal Load Capacitance Range (CL) 6pF 9pF 12pF See below for more details Not all Combinations of Crystal Load Capacitance and ESR are Valid Recommended Crystal Load Capacitance 9pF and max ESR 40 Ω External Capacitors (C1 & C2) For recommended Crystal 15pF CL = 9pF, total external capacitance needs to be 2*CL. , allowing for stray capacitance from chip, package and PCB © NXP Laboratories UK 2013 JN-DS-JN5148-001 1v9 91 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. 32MHz Crystal Oscillator 4.1 4.15 4.2 4.25 4.3 4.35 -40 -20 0 20 40 60 80 100 Temperature (C) Transconductance (mA/V) 32MHz Crystal Oscillator 4.28 4.29 4.3 4.31 2 2.2 2.4 2.6 2.8 3 3.2 3.4 3.6 Supply Voltage (VDD) Transconductance (mA/V)92 JN-DS-JN5148-001 1v9 © NXP Laboratories UK 2013 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. 32kHz Crystal Requirements Parameter Min Typ Max Notes Crystal Frequency 32kHz Supply Current 1.6uA Vdd=3v, temp=25 C, load cap =9pF, Rm=25K Supply Current Temp.

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.

Laboratories UK 2013 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 1.3 Peripherals The following peripherals are available on chip: • Master SPI port with three select outputs • Slave SPI port • Two UART’s, one capable of hardware flow control (4-wire, includes RTS/CTS), and the other just 2-wire (RX/TX) • One programmable Timer/Counter which supports Pulse Width Modulation (PWM) and capture/compare, plus four PWM timers which support PWM and Timer modes only. • Two programmable Sleep Timers and a Tick Timer • Two-wire serial interface (compatible with SMbus and I2 C) supporting master and slave operation • Twenty digital I/O lines (multiplexed with peripherals such as timers, SPI and UARTs) • Two digital outputs (multiplexed with SPI port) • 10-bit, Analogue to Digital converter with up to four input channels.

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. VDD1 Analogue I/O Pin VSSA Analogue Peripheral Figure 3: Analogue I/O Cell 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 O VDD2 Pu RPU OE DIO[x] Pin RESD ADC or COMP1 Input I IE RPROT VSS VSS 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 4 Memory Organisation This section describes the different memories found within the JN516x. The device contains Flash, RAM, and EEPROM memory, the wireless transceiver and peripherals all within the same linear address space. 0xFFFFFFFF Unpopulated 0xF0008000 RAM 0x04000000 0x02000000 FLASH Boot Code 8K 0x000C0000 0x00000000 0x00080000 Flash & EEPROM Registers 0x01000000 Peripherals FLASH Applications Code (256KB) 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) JN516x Serial Memory SPISEL0 SPIMISO SPIMOSI SPICLK SS SDO SDI CLK 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). High Speed RC Oscillator 32MHz Crystal Oscillator Div by 1,2,4,8,16 or 32 Div by 2 PERIPHERAL SYSTEM CLOCK CPU CLOCK 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 XTALOUT 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. 32KXTALIN 32KXTALOUT 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 RESETN C1 R1 JN516x VDD 18k 470nF 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. Internal Reset RESETN pin Reset 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. 8.1 Radio Figure 13 shows the single ended radio architecture. LNA synth PA ADC Reference & Bias Switch Radio Calibration Lim1 Lim2 Lim3 Lim4 sigma delta D-Type 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 R1 43K IBIAS C20 100nF L2 3.9nH VB_RF VREF VB_RF2 RF_IN C3 100nF C12 47pF VB_RF1 C1 47pF L1 5.1nH To Coaxial Socket or Integrated Antenna VB_RF Figure 14: External Radio Components 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).

AGC Demodulation Symbol Detection (Despreading) Modulation Spreading TX RX TX Data Interface RX Data Interface VCO Sigma-Delta Modulator IF Signal Gain Figure 17: Modem Architecture 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 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. Figure 18: Energy Detect Value vs Receive Power Level30 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013 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. Supervisor Append Checksum Serialiser DMA Engine TX Stream Radio Protocol Timing Engine CSMA CCA Backoff Control Control RX Stream Verify Checksum Deserialiser Protocol Timers Security Coprocessor AES Codec Encrypt Port Decrypt Port Status Processor Bus Figure 19: 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. Processor Interface AES Block Encryption Controller AES Encoder Key Generation Figure 20: Security Coprocessor Architecture 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 MUX SPI Slave DIO0/SPISEL1/ADC3 DIO1/SPISEL2/ADC4/PC0 DIO2/RFRX/TIM0CK_GT DIO3/RFTX/TIM0CAP DIO4/CTS0/TIM0OUT/PC0 DIO5/RTS0/PWM1/PC1 DIO6/TXD0/PWM2 DIO7/RXD0/PWM3 DIO8/TIM0CK_GT/PC1/PWM4 DIO9/TIM0CAP/32KXTALIN/RXD1/32KIN DIO10/TIM0OUT/32KXTALOUT DIO11/PWM1/TXD1 DIO12/PWM2/CTS0/ADO/SPISMOSI DIO13/PWM3/RTS0/ADE/SPISMISO DIO14/SIF_CLK/TXD0/TXD1/SPISEL1/SPISSEL DIO15/SIF_D/RXD0/RXD1/SPISEL2/SPISCLK DIO16/COMP1P/SIF_CLK/SPISMOSI DIO17/COMP1M/SIF_D/SPISMISO DIO18/SPIMOSI DIO19/SPISEL0 DO0/SPICLK/PWM2 DO1/SPIMISO/PWM3 TXD0 SPI Master UART0 UART1 RXD0 RTS0 CTS0 TxD1 RxD1 TIM0CK_GT TIM0OUT TIM0CAP PWM1 PWM2 PWM3 PWM4 SIF_D SIF_CLK PC0 PC1 JTAG_TDI JTAG_TMS JTAG_TCK JTAG_TDO ADO ADE Timer0 PWMs 2-wire Interface Pulse Counters JTAG Debug Antenna Diversity SPICLK SPIMOSI SPIMISO SPISEL0 SPICLK SPIMOSI SPIMISO SPISEL0 SPISEL1 SPISEL2 Figure 21 DIO Block Diagram34 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013 10 Serial Peripheral Interface 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 • LSB First or MSB First Data Transfer • Supports delayed read edges Clock Divider SPI Bus Cycle Controller Data Buffer DIV Clock Edge Select Data CHAR_LEN LSB SPIMISO SPIMOSI SPICLK Select Latch SPISEL [2..0] 16 MHz Figure 22: SPI Master 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. 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 for the SPISEL signals depending upon the configuration.

When the device reset is active, all the SPI Master pins are configured as inputs with their pull-up resistors active. The pins stay in this state until the SPI Master block is enabled, or the pins are configured for some other use.

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. SPICLK Polarity Mode Description (CPOL) Phase (CPHA) 0 0 0 SPICLK is low when idle – the first edge is positive. Valid data is output on SPIMOSI before the first clock and changes every negative edge. SPIMISO is sampled every positive edge. 0 1 1 SPICLK is low when idle – the first edge is positive. Valid data is output on SPIMOSI every positive edge. SPIMISO is sampled every negative edge. 1 0 2 SPICLK is high when idle – the first edge is negative.

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. 0 1 2 3 4 5 6 7 Instruction (0x03) 23 22 21 3 2 1 0 8 9 10 28 29 30 31 24-bit Address MSB Instruction Transaction 7 6 5 4 3 2 1 0 MSB 0 1 2 3 4 5 7 8N-1 3 2 1 0 LSB Read Data Bytes Transaction(s) 1-N SPISEL SPICLK SPIMOSI SPIMISO SPISEL SPICLK SPIMOSI SPIMISO 8 9 10 7 6 5 MSB Byte 1 Byte 2 Byte N value unused by peripherals 6 Figure 24: Example SPI Waveforms – Reading from FLASH Device using Mode 0© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 37 10.2 Serial Peripheral Interface Slave 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 following table. Signal DIO Assignment Standard pins Alternative pins SPISCLK DIO15 SPISMISO DIO13 DIO17 SPISMOSI DIO12 DIO16 SPISSEL DIO14 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. >= D Q Rise = < Fall Delta Sigma Interrupt Generator Counter Interrupt Enable Capture Generator Prescaler SYSCLK TIMxCK_GT TIMxCAP Interrupt PWM/∆Σ PWM/∆Σ PWM/∆Σ Reset Generator Edge Select EN EN TIMxOut Sw Reset System Reset Single Shot -1 Figure 25: Timer Unit Block Diagram© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 39 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 following table details which DIO are used for timer0 and the PWM depending upon the configuration. Signal DIO Assignment Standard pins Alternative pins TIM0CK_GT DIO8 DIO2 TIM0CAP DIO9 DIO3 TIM0OUT DIO10 DIO4 PWM1 DIO11 DIO5 PWM2 DIO12 DIO6 PWM3 DIO13 DIO7 PWM4 DIO17 DIO8 Table 5: Timer and PWM IO 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. Rise 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 CLK CAPT x 9 3 x 14 t RISE t RISE t FALL t FALL Rise Fall 9 5 3 4 7 Capture Mode Enabled Figure 27: Capture Mode 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 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 1 2 3 1 2 N Conversion cycle 1 217 N Conversion cycle 2 3 Figure 28: Return To Zero Mode in Operation 1 2 3 1 2 N Conversion cycle 1 N 3 216 Conversion cycle 2 Figure 29: Non-Return to Zero Mode 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.

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 Match Value Counter = Mode Control & & SysClk Run Match Int Enable Tick Timer Interrupt Reset Mode 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 Divisor Latch Registers Line Status Register Line Control Register FIFO Control Register Receiver FIFO Transmitter FIFO Baud Generator Logic Transmitter Shift Register Receiver Shift Register Transmitter Logic Receiver Logic RXD TXD Modem Control Register Modem Status Register Modem Signals Logic RTS CTS Interrupt ID Register Interrupt Enable Register Interrupt Logic Internal Interrupt 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. Signal DIO Assignment Standard pins Alternative pins CTS0 DIO4 DIO12 RTS0 DIO5 DIO13 TXD0 DIO6 DIO14 RXD0 DIO7 DIO15 TXD1 DIO14 DIO11 RXD1 DIO15 DIO9 Table 6: UART IO . 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. 13.2 UART Application The following example shows the UART0 connected to a 9-pin connector compatible with a PC. As the JN516x device pins do not provide the RS232 line voltage, a level shifter is used.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 47 JN516x RTS CTS TXD RXD UART0 RS232 Level Shifter 1 2 3 4 5 6 7 8 9 CD RD TD DTR SG DSR RTS CTS RI PC COM Port 1 5 Pin Signal 6 9 Figure 33: JN516x Serial Communication Link48 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013 14 JTAG Test Interface The JN516x includes an IEEE1149.1 compliant JTAG port for the purpose of manufacturing test. The software debugger is not supported with this product. The JTAG interface does not support boundary scan testing. It is recommended that the JN516x is not connected as part of the board scan chain.© NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 49 15 Two-Wire Serial Interface (I2 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 upon the configuration. Signal DIO Assignment Standard pins Alternative pins SIF_CLK DIO14 DIO16 SIF_D DIO15 DIO17 Table 7: Two-Wire Serial Interface IO 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 SIF_CLK SIF_D VDD D1_OUT D1_I N CLK1_I N CLK1_OUT D2_I N CLK2_I N CLK2_OUT DEVICE 1 DEVICE 2 RP RP Pullup Resistors D2_OUT JN516x SI F DIO14 DIO15 Figure 34: Connection Details 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. SIF_CLK SIF_CLK SIF_CLK Master SIF_CLK Slave SIF_CLK Wired-AND SIF_CLK Clock held low by Slave Figure 35: Clock Stretching 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 SIF_CLK1 SIF_CLK2 SIF_CLK Master1 SIF_CLK Master2 SIF_CLK Wired-AND SIF_CLK Start counting low period Start counting high period Wait State Figure 36: Multi-Master Clock Synchronisation 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. Address Name Behaviour 0000 000 General Call/Start Byte Ignored 0000 001 CBUS address Ignored 0000 010 Reserved Ignored 0000 011 Reserved Ignored 0000 1XX Hs-mode master code Ignored 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 17 Analogue Peripherals The JN516x contains a number of analogue peripherals allowing the direct connection of a wide range of external sensors and switches. ADC Supply Voltage (VDD1) COMP1M (DIO17) Comparator 1 COMP1P (DIO16) ADC1 VREF/ADC2 ADC3 (DIO0) ADC4 (DIO1) Vref Internal Reference Vref Select Chip Boundary Temp Sensor Figure 37: Analogue Peripherals 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. VREF Gain Setting Maximum Input Range Supply Voltage Range (VDD) 1.2V 1.6V 1.2V 1.6V 0 0 1 1 1.2V 1.6V 2.4V 3.2V 2.2V - 3.6V 2.2V - 3.6V 2.6V - 3.6V 3.4V - 3.6V 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. ADC pin 5 K 8 pF Sample Switch ADC front end 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. For detailed electrical specifications, see Section 19.3.7.56 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013 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 19 Electrical Characteristics 19.1 Maximum Ratings Exceeding these conditions may result in damage to the device.

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 = 1 2 1 2 T T T T 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 2 T1× T 2 ×ω m C C g ≥ 2 4         + L S L m C C C R This can be used to give an equation for the required transconductance. 1 2 2 1 2 1 2 2 4 [ ( ) ] T T m S T T T T m C C R C C C C C g × × + + × ≥ 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. XTALOUT C1 C2 XTALIN R1 JN516x Figure 52: Crystal Oscillator Connections The clock generated by this oscillator provides the reference for most of the JN516x subsystems, including the transceiver, processor, memory and digital and analogue peripherals. 32MHz Crystal Requirements Parameter Min Typ Max Notes Crystal Frequency 32MHz Crystal Tolerance 40ppm Including temperature and ageing Crystal ESR Range (Rm) 10Ω 60Ω See below for more details Crystal Load Capacitance Range (CL) 6pF 9pF 12pF See below for more details Not all Combinations of Crystal Load Capacitance and ESR are Valid Recommended Crystal Load Capacitance 9pF and max ESR 40 Ω External Capacitors (C1 & C2) For recommended Crystal 15pF CL = 9pF, total external capacitance needs to be 2*CL. , allowing for stray capacitance from chip, package and PCB 86 JN-DS-JN516x v1.3 Production © NXP Laboratories UK 2013 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. 4.15 4.20 4.25 4.30 4.35 -40 -20 0 20 40 60 80 100 120 Transconductance (mA/V) Temperature (C) 32MHz Crystal Oscillator 4.27 4.28 4.29 4.3 4.31 4.32 4.33 4.34 4.35 2 2.2 2.4 2.6 2.8 3 3.2 3.4 3.6 Transconductance (mA/V) Supply Voltage (VDD) 32MHz Crystal Oscillator © NXP Laboratories UK 2013 JN-DS-JN516x v1.3 Production 87 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. 32kHz Crystal Requirements Parameter Min Typ Max Notes Crystal Frequency 32kHz Supply Current 1.4µA Vdd=3v, temp=25 C, load cap =9pF, Rm=25K Supply Current Temp.

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 Related Documents [1] IEEE Std 802.15.4-2006 IEEE Standard for Information Technology – Part 15.4 Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Low-Rate Wireless Personal Area Networks (LR-WPANs).

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.

Product data sheet Rev. 5 — 9 September 2014 41 of 122 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. Table 6.

Product data sheet Rev. 5 — 9 September 2014 44 of 122 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 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. Product data sheet Rev. 5 — 9 September 2014 57 of 122 NXP Semiconductors LPC178x/7x 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.

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. Table 8.

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.

Product data sheet Rev. 5 — 9 September 2014 60 of 122 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.

Product data sheet Rev. 5 — 9 September 2014 61 of 122 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. Fig 7.

Product data sheet Rev. 5 — 9 September 2014 62 of 122 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. Fig 8.

Product data sheet Rev. 5 — 9 September 2014 67 of 122 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.

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.

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.

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.

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. Table 4.

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.

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.

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. 7.17.4.1 Features • Dynamic memory interface support including single data rate SDRAM. • Asynchronous static memory device support including RAM, ROM, and NOR 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: – Asynchronous page mode read – Programmable Wait States – Bus turnaround delayLPC4350_30_20_10 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

Product data sheet Rev. 4.2 — 18 August 2014 77 of 155 NXP Semiconductors LPC4350/30/20/10 32-bit ARM Cortex-M4/M0 microcontroller The I2S-bus provides a standard communication interface for digital audio applications. 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-bus connection has one master, which is always the master, and one slave. The I2S-bus interface provides a separate transmit and receive channel, each of which can operate as either a master or a slave. 7.18.6.1 Features • The I2S 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 192 kHz (16, 22.05, 32, 44.1, 48, 96, 192) kHz. • Support for an audio master clock. • Configurable word select period in master mode (separately for I2S-bus input and output). • Two 8-word FIFO data buffers are provided, one for transmit and one for receive. • Generates interrupt requests when buffer levels cross a programmable boundary. • Two DMA requests controlled by programmable buffer levels.

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.

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.

Product data sheet Rev. 4.2 — 18 August 2014 81 of 155 NXP Semiconductors LPC4350/30/20/10 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.

Product data sheet Rev. 4.2 — 18 August 2014 82 of 155 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 32fs, 64fs, 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.

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.

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. Tj Tamb PD Rth j a   – +=    Table 7.

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. [7] Tamb = 25 C. [8] Input resistance Ri depends on the sampling frequency fs: Ri = 2 k + 1 / (fs  Cia). Table 34.

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.

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. Fig 44.

Product data sheet Rev. 4.2 — 18 August 2014 137 of 155 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: 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.

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). Table 4.

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. Fig 4.

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. Table 6.

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. Fig 7.

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.

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.

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. Table 20.

All rights reserved. Product data sheet COMPANY PUBLIC Rev. 3.7 — 27 February 2014 073937 22 of 127 NXP Semiconductors CLRC632 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.

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. Table 22.

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]. Fig 8.

All rights reserved. Product data sheet COMPANY PUBLIC Rev. 3.7 — 27 February 2014 073937 25 of 127 NXP Semiconductors CLRC632 Standard multi-protocol reader solution 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. fTimerClock 1 TTimerClock --------------------------- 2 TPreScaler 13.56 = = -------------------------- MHz tTimer TReLoadValue TimerValue – fTimerClock = ----------------------------------------------------------------------------- sCLRC632 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2014.

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. Fig 9. TimeSlotPeriod Table 23.

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. 9.5.3 Timer unit registers Table 24 shows the related flags of the timer unit in alphabetical order. t TReLoadvalue   – TimerValue tTimer =  Table 24.

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. Table 25.

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. Fig 10.

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. Fig 11.

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. 9.9.1 Configuring pins TX1 and TX2 TX1 pin configurations are described in Table 26.

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.

(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.

Product data sheet COMPANY PUBLIC Rev. 3.7 — 27 February 2014 073937 35 of 127 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. Fig 12.

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 Gain[1:0] bits; see Table 29. Fig 13.

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.

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.

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. Fig 15.

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. Table 36.

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.
