Jennic launch 3rd generation Zigbee PRO Wireless Microcontroller and Module

Reading, UK 20th May 2009: Sequoia Technology, the technology solutions provider specialising in wireless communications announces a new platform of IEEE802.15.4 and Zigbee PRO single chip MicroController and Modular products based on the new Jennic JN5148 32 bit RISC processor.

The combination of the lowest operating current consumption and highest memory density of any single chip wireless microcontroller, plus an innovative Time of Flight ranging engine, will enable the development of next generation wireless mesh networks for battery powered and data rich applications.

The JN5148 32 bit wireless microcontroller achieves a system operation current consumption of 18mA when receiving and 15mA in transmit at +3dBm, which is typically 35% lower than current solutions. With 128kB ROM and 128kB RAM and advanced coding efficiency giving better code compression, the JN5148 has sufficient space for developers to integrate their embedded application softare and the ZigBee PRO protocol stack into a single chip. It can also be used as a co-processor, enabling ZigBee PRO to be added easily and quickly to existing systems.

Programmable CPU clock speeds from 4 to 32MHz and the use of five seperate power domains provides the ability to select low power or high performance up to 32 MIPS CPU operation enabling the JN5148 to be used across the full range of applications - from low power battery backed networks to high I/O, processor intensive systems. A unique patent pending Time of Flight ranging engine integrated into the device revolutionises location based services for sensor networks by providing improved accuracy over conventional signal strength based systems with little incremental cost.

The first version of the JN5148 is offered with Jennic's Zigbee PRO stack and is supported by a comprehensive range of evaluation and development kits as well as reference designs, code examples and an online developer forum. In addition to the the standalone wireless controller, the JN5148 is available in a fully integrated uFL module optimised for standard power, or a +20dBm high power, providing a rapid and easy to implement route to product introduction.

David Taylor, Sequoia Product Manager for Jennic explains; "Jennic products are designed to provide a fast route to high performance wireless network development by combining field proven stacks with innovative silicon features. A responsive support environment enables developers with little or no experience of mesh networks the ability to realise their ambitious designs quickly and easily.
