Second-generation wireless microcontrollers cheaper and better

7 February 2007 DSP, Micros & Memory

Jennic claims its new second generation wireless microcontrollers, the JN513x family, achieve new industry performance and price points for IEEE802.15.4 and ZigBee wireless technology products. According to the company the JN513x family realises a number of improvements over the existing solution: extended range is achieved with a new modem architecture that provides 97 dB receive sensitivity, and is more robust in noisier environments with greater tolerance to carrier offset and EVM. Deep sleep current consumption is lowered to 400 nA; The memory available has been increased to 192 KB ROM and 96 KB RAM, allowing full exploitation of the on-chip 32-bit RISC processor for complex applications and algorithms coupled with ZigBee or other mesh protocol stacks; The on-chip ROM includes the world's first IEEE802.15.4 version B media access protocol layer, provision for a range of external serial EEPROM devices, over-the-air download, hardware abstraction layers and a simple serial interface; Each device shipped has a unique MAC address identifier allowing the saving of external FLASH devices; Package and pin-out of the JN513x remains the same as the first generation JN5121 (56-pin QFN package), allowing easy upgrades of current designs.
