3. Product Development

Jennic supplies all the development tools and networking stacks needed to enable end product development to occur

quickly and efficiently. These are all freely available from Jennic’s support website: http://www.jennic.com/support/ .

A range of evaluation/developer kits is also available, allowing products to be quickly breadboarded. Efficient

development of software applications is enabled by the provision of a complete, unlimited, software developer kit.

Together with the available libraries for the JenNet networking stack, the IEEE802.15.4 MAC and the ZigBee network

stack, this package provides everything required to develop application code and to trial it with hardware

representative of the final module.

The modules can be user programmed both in development and in production using software supplied by Jennic.

They can also be supplied ready loaded with customer defined software if required. Access to the on-chip

peripherals, MAC and network stack software is provided through specific APIs. This information is available on the

Jennic support website, together with many example applications, user guides, reference manuals and application

notes.

3.1. JN5139 Single Chip Wireless Microcontroller

The JN5139-xxx-Myy series is constructed around the JN5139 single chip wireless microcontroller, which includes

the radio system, a 32-bit RISC CPU, ROM and RAM memory and a range of analogue and digital peripherals.

The chip is described fully in JN-DS- JN513x Wireless Microcontroller Datasheet [2].

The module also includes a 1Mbit serial flash memory which holds the application code that is loaded into the

JN5139 during the boot sequence.
