IEEE802.15.4 Wireless Microcontroller
Overview
The JN516x series is a range of ultra low power, high performance wireless
microcontrollers supporting JenNet-IP, ZigBee PRO or RF4CE networking
stacks to facilitate the development of Home Automation, Smart Energy,
Light Link and Remote control applications. They feature an enhanced 32-
bit RISC processor with embedded Flash and EEPROM memory, offering
high coding efficiency through variable width instructions, a multi-stage
instruction pipeline and low power operation with programmable clock
speeds. They also include a 2.4GHz IEEE802.15.4 compliant transceiver
and a comprehensive mix of analogue and digital peripherals. Three
memory configurations are available to suit different applications. The best
in class operating current of 15mA, with a 0.6uA sleep timer mode, gives
excellent battery life allowing operation direct from a coin cell.
The peripherals support a wide range of applications. They include a 2-wire
I2C, and SPI ports which can operate as either master or slave, a four
channel ADC with battery and a temperature sensor. It can support a large
switch matrix of up to 100 elements, or alternatively a 20 key capacitive
touch pad.

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 .

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.
