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 bread boarded. Efficient

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

Together with the available libraries for 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 for 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. JN5148 Single Chip Wireless Microcontroller

The JN5148-001-Myy series is constructed around the JN5148-001 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- JN5148 Wireless Microcontroller Datasheet [2].

The module also includes a 4Mbit serial flash memory, which holds the application code that is loaded into the

JN5148 during the boot sequence and provides static data storage, required by the application.
