Jennic’s new single-chip wireless microcontroller is suitable for ZigBee PRO and IEEE802.15.4 wireless mesh networking. Jennic’s new single-chip wireless microcontroller, available from Glyn High-Tech Distribution has the following benefits:

  • Low system operating current of any single-chip wireless microcontroller
  • Integrates more memory and has ample space for ZigBee PRO, either embedded together with an application, or as a co-processor
  • Provides location-based services for sensor networks with a time of flight ranging engine
  • Available as a standalone wireless controller chip or fully integrated module family for easy design-in and fast time to market

Jennic, available from GLYN High-Tech Distribution, have announced a new single-chip 32-bit wireless microcontroller, which is suitable for wireless networking communications based on the ZigBee PRO and IEEE802.15.4 standards. The combination of the low operating current consumption and high memory density of any single-chip wireless microcontroller, plus a time of flight ranging engine enables the development of next-generation wireless mesh networks for battery-powered and data-rich applications.

The JN5148 32-bit wireless microcontroller has a system operating current consumption of 18mA when receiving, and 15mA transmitting at +3dBm. With 128kB ROM, 128kB RAM and enhanced coding efficiency, the JN5148 32-bit wireless microcontroller has sufficient space for developers to integrate their embedded application software 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 to existing systems.

Programmable CPU clock speeds from 4 to 32MHz and the use of five separate power domains provide the ability to select low power or high performance up to 32 MIPS CPU operation for the JN5148 wireless microcontroller to be used across the range of applications from low-power battery-backed networks to high I/O, processor intensive systems.

A time of flight ranging engine integrated into the device is suitable for location-based services such as sensor networks by providing improved accuracy. According to Jennic, their products are designed to provide a fast route to high-performance wireless network development by combining stacks with silicon features. A responsive support environment brings high-performance network development to designers.

The JN5148 wireless microcontroller integrates a high-performance 32-bit RISC CPU core with mixed-signal peripherals and an IEEE802.15.4, 2.4GHz transceiver. The 98dB link budget and selectable high data-rate modes support indoor communication over distances of up to 50 meters, while 128-bit AES encryption ensures a high level of security.

The implementation of the JN5148 wireless microcontroller requires the following additional devices:

  • A crystal
  • Discrete passives
  • A serial Flash memory
  • External components under 50°C

The first version of the JN5148 wireless microcontroller is offered with Jennic’s ZigBee PRO stack and is supported by a range of evaluation and development kits as well as reference designs, code examples and an online developer forum. In addition to the standalone wireless controller, the JN5148 wireless microcontroller is available in a fully integrated uFI module optimised for +2.5dBm standard power, or +20dBm high-power, providing an easy to implement route to product introduction.
