7/3/2009 - Jennic unveils 32-bit wireless microcontroller

Jennic has announced a single-chip 32-bit wireless microcontroller for networking communications based on the Zigbee Pro and IEEE802.15.4 standards.

The JN5148 32-bit wireless microcontroller achieves a system operating current consumption of 18mA when receiving, and 15mA when transmitting at +3dBm.

With 128KB ROM, 128KB RAM and enhanced coding efficiency, the JN5148 has sufficient space for developers to integrate 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 quickly added to existing systems.

Programmable CPU clock speeds from 4MHz 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 to be used across the full 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 useful for location-based services for sensor networks.

The engine provides improved accuracy over conventional signal-strength-based systems with little incremental cost, said Jennic.
