IEEE802.15.4/ZigBee module speeds wireless sensor design


LONDON — Jennic has developed a range of IEEE802.15.4/ZigBee modules to speed the development of wireless sensor based products.

The JN5121MOxxx range of modules, based on the Jennic JN5121 single chip wireless microcontroller, is to enable developers of sensor network products avoid the effort involved in designing RF circuitry and test solutions.

The modules also provide a production proven reference design and manufacturing package for other module suppliers developing their own wireless sensor modules for the end-market.

The modules provide developers with access to the full digital and analog IO capability of the JN5121 chip, including ADC, DAC, comparators, timers, UART, serial interfaces as well as GPIO. The JN5121MOxxx's IO access ensures the module can be used without having to add additional circuitry to implement all of the functionality required in many low power wireless systems.

The JN5121MOxxx family includes versions with integrated ceramic antennas or with an SMA connector for ranges of up to about 200m, in a surface mount form factor of 18 x 30mm. There is also a version with an integrated power amplifier and low noise amplifier for extended range (over 1km) applications, measuring 18x40mm. Each module is supplied with IEEE802.15.4 MAC layer software, or with ZigBee network stack.

Jennic recently said it is working with Taiwan's Institute for Information Industry (III) to provide a ZigBee stack on its JN5121 microcontroller for Asia-Pacific market.
