Wireless microcontroller supports ZigBee Pro

Edited by the Electronicstalk editorial team Jun 24, 2008

Software stack and processor combine to provide a high-performance feature-rich implementation that supports both the ZigBee Pro protocol and the user's application.

Jennic has come up with a ZigBee Pro software stack to run on its JN5139 32bit single-chip wireless microcontroller.

Both embedded single chip and coprocessor configurations are supported, allowing designers of industrial automation, energy metering and home or building control applications to create highly integrated cost-effective products.

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 coprocessor, 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 explains: "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, 32bit single chip or coprocessor 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 32bit wireless microcontroller combines the ZigBee Pro stack with significant internal memory resources and power management for minimising energy consumption.

The microcontroller features 192Kbyte of on-chip ROM for the IEEE802.15.4 MAC and 96Kbyte of RAM for application software.

It also integrates on-chip UARTs, SPI and two-wire serial (I2C) interfaces, general purpose I/O (GPIO), timers, a 12bit ADC, DAC and comparators, and 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 128bit AES encryption.
