1 Introduction
The JN5139-001 and JN5139-Z01 are IEEE802.15.4 wireless microcontrollers that provide a fully integrated solution
for applications using the IEEE802.15.4 and ZigBee standards in the 2.4 - 2.5GHz ISM frequency band [1]. They
include all of the functionality required to meet the IEEE802.15.4 specification and have additional processor
capability to run a wide range of applications including but not limited to Remote Control, Home and Building
Automation, Toys and Gaming. The following table explains which software stack is compatible with which chip
variant:

The devices include a Wireless Transceiver, RISC CPU, on-chip memory and an extensive range of peripherals.
Hereafter, the JN5139-001 and JN5139-Z01 will be referred to collectively as JN5139.
1.1 Wireless Microcontroller
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, Jennic provides a series of software libraries and interfaces that control the
transceiver and peripherals of the JN5139. 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 JN5139 are not provided in the datasheet.
1.2 Wireless Transceiver
The Wireless Transceiver is highly integrated and, together with the integrated IEEE802.15.4 MAC library contained
in ROM requires little knowledge of RF or wireless design.
The Wireless Transceiver comprises a low-IF 2.45GHz radio, an O-QPSK modem, a baseband controller and a
security coprocessor. The radio has a 200Ω resistive differential antenna port that includes all the required matching
components on-chip, allowing a differential antenna to be connected directly to the port, minimising the system BOM
costs. Connection to a single ported antenna can be achieved using a 200/50Ω 2.45GHz balun. 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.
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 under the control of a protocol stack.
(1) AES-CBC processing is only available off-line for use under software control.
1.3 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 JN5139 has a unified memory architecture,
code memory, data memory, peripheral devices and I/O ports are organized within the same linear address space.
The device contains 192kBytes of ROM, 96kBytes of RAM and a 48-byte OTP eFuse memory.
