Jennic's 32-bit ZigBee PRO wireless microcontroller

When operating as an embedded single chip the software stack and processor provide a high performance, feature-rich implementation that supports both the ZigBee PRO protocol and the user’s application. As a co-processor, it allows ZigBee PRO networking functionality to be easily added to existing designs and applications. To accelerate time to market ZigBee PRO is also offered with Jennic’s comprehensive range of FCC and ETSI certified modules, removing RF design complexity.

Jim Lindop, Jennic’s CEO explained; “The ZigBee PRO stack is a natural extension to the Jennic product portfolio. This gives customers the flexibility they need to design wireless networks by combining the best-fit protocol for each application with a cost-effective, 32-bit single chip or co-processor implementations. Designers can confidently decide to use Jennic’s own proprietary JenNet stack, 6LoWPAN IP stack or ZigBee PRO, with the knowledge that they will have the tools and support to ensure a fast route to market.”

Jennic’s JN5139 32-bit wireless microcontroller combines the ZigBee PRO stack with significant internal memory resources and power management for minimising energy consumption. The microcontroller features 192kBytes of on-chip ROM for the IEEE802.15.4 MAC and 96kBytes of RAM for application software. It also integrates on-chip UARTs, SPI and 2-wire serial (I2C) interfaces, general purpose I/O (GPIO), timers, a 12-bit ADC, DAC and comparators, whilst power consumption is maintained below 5uA in low-power sleep mode. The integrated 2.4GHz, IEEE802.15.4-based transceiver supports a 100dB link for indoor communication over 30-50m, as well as secure 128-bit AES encryption.
