Overview
The JN5139 is a low power, low cost wireless microcontroller suitable for
IEEE802.15.4 and ZigBee applications. The device integrates a 32-bit RISC
processor, with a fully compliant 2.4GHz IEEE802.15.4 transceiver, 192kB of ROM,
96kB of RAM, and a rich mixture of analogue and digital peripherals.
The cost sensitive ROM/RAM architecture supports the storage of system
software, including protocol stacks, routing tables and application code/data. An
external flash memory is used to store application code that is bootloaded into
internal RAM and executed at runtime.
The device integrates hardware MAC and AES encryption accelerators, power
saving and timed sleep modes, and mechanisms for security key and program
code encryption. These features all make for a highly efficient, low power, single
chip wireless microcontroller for battery-powered applications.

Design Flexibility
Battery Optimisation
To maximise battery life, devices support a series of power
management and sleep modes. Used effectively, these will allow a
batteries life expectancy for a typical remote sensing application, to
be of the order of a few years.
Wireless Protocol Stacks in ROM
Two standard ROM configurations are available that integrate IEEE802.15.4b and ZigBee protocol stacks. The JN5139-000
integrates IEEE802.15.4b for development of proprietary systems, and the JN5139-Z01 integrates the ZigBee protocol stack,
this supporting co-ordinator, router and end device configurations. Custom ROM masks will support the integration of user
code into ROM, attractive to higher volume applications.
Application Diagram
The JN5139 device requires a minimum of external
components to support wireless applications; a crystal,
some decoupling components and printed antenna are
all that is required for the lowest cost bill of materials and
smallest size (an external bootloader flash may be used
for optional program code storage).
Evaluation Kits
To assist users with the development of wireless sensor networks, Jennic provide a series of Evaluation Kits. These contain
everything that is needed to carry out complete development and test, and include controller and sensor boards, interface
dongle to connect with a PC and a Software Developer Kit (SDK).
The SDK provides a comprehensive suite of tools to facilitate the development of application code. The kit includes a C
compiler, graphical and text debuggers, assembler, linker and flash programmer. A set of libraries provides a simple
Application Programming Interface (API) to drive the peripherals of the controller and sensor boards.
