Product data sheet
1. General description
The JN517x series is a range of ultra low power, high performance wireless
microcontrollers suitable for Thread and ZigBee applications to facilitate the development
of Smart Home and Smart Lighting applications. It features a high-performance and
low-power ARM Cortex-M3 processor with debug with programmable clock speeds. The
JN517x devices are available in JN5174, JN5178 and JN5179 variants, respectively
having 160 kB, 256 kB and 512 kB of embedded Flash memory as well as 32 kB of RAM
and 4 kB of EEPROM. The embedded Flash can support “Over-The-Air” code download
of software stacks. Radio transmit power is configurable up to +10 dBm output. The
very-low receive operating current (down to 12.7 mA and with a 0.6
A
sleep timer mode)
gives excellent battery life allowing operation direct from a coin cell. The JN517x also
includes a 2.4 GHz “IEEE802.15.4 compliant” transceiver and a comprehensive mix of
analog and digital peripherals.
The JN517x is ideal for battery-operated applications supported through the
comprehensive power-saving modes available in the device. The on-chip peripherals,
which include a fail-safe I
2
C-bus, SPI-bus ports (both master and slave), and a
six-channel analog-digital converter with internal temperature sensor support a wide
range of applications directly without extra hardware.

4. Overview
The JN517x 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 GHz to 2.5 GHz ISM
frequency band, including ZigBee PRO and Thread.
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 minimize this complexity, NXP provides a series of software libraries and
interfaces that control the transceiver and peripherals of the JN517x. 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 JN517x in the
data sheet.
The device includes a wireless transceiver, ARM Cortex-M3 CPU, “on-chip memory” and
an extensive range of peripherals.
4.1 Wireless transceiver
The wireless transceiver comprises a 2.45 GHz 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 realized very easily.
Section 15.1
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.
The transmitter is equipped with a power amplifier with 3 options for transmit power (major
steps, fine steps and attenuator) see
Figure 51.

functionality can be developed rapidly by combining user-developed application software
with a protocol stack library.
4.2 CPU and memory
An ARM Cortex-M3 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 JN517x has a unified memory architecture, where code memory,
data memory, peripheral devices and IO ports are organized within the same linear
address space. The device contains 160 kB or 256 kB or 512 kB of Flash and 32 kB of
RAM and 4 kB EEPROM.

The following peripherals are available on chip:
•
Master SPI-bus port with 2 simultaneous select outputs

User applications access the peripherals using the Integrated Peripherals API. For further
details, refer to the JN517x Integrated Peripherals API User Guide, JN-UG-3118 on the
Wireless Connectivity area of the NXP web site
Ref. 2.
This allows applications to use a
tested and easily understood view of the peripherals allowing rapid system development.
