Wireless microcontroller family targets the Internet of Things

November 20, 2012 // By Jean-Pierre Joosting
NXP Semiconductors has unveiled the JN516x family – its next generation of ultra-low-power wireless microcontrollers for JenNet-IP, ZigBee and other IEEE 802.15.4 applications.

Integrating a 2.45-GHz radio and analog peripherals with microcontroller functionality in a single die, the JN516x wireless microcontrollers are the only single-chip devices in the industry to support JenNet-IP, ZigBee Light Link, ZigBee Smart Energy, ZigBee Home Automation and RF4CE. The JN516x family also offers best-in-class memory options, with up to 256 kB of embedded flash, 4 kB of on-chip EEPROM and 32 kB of RAM on the JN5168 to support the latest network stacks.  Another key feature is in-packet antenna diversity, which allows systems to choose the best antenna on every packet received.

Currently sampling with lead customers, JN516x evaluation kits and chips will be available from leading distributors in January 2013.

The JN516x wireless microcontroller family includes JN5161 for RF4CE and IEEE 802.15.4 applications with 64 kB flash, 8 kB RAM, 4 kB EEPROM; JN5164 for JenNet-IP, ZigBee Home Automation and ZigBee Light Link applications with 160 kB flash, 32 kB RAM, 4 kB  EEPROM; JN5168 for ZigBee Smart Energy applications and JenNet-IP gateways with 256 kB flash, 32 kB RAM, 4 kB EEPROM.

There is also a single evaluation kit suitable for all stacks as well as a new range of modules using the JN5168 chip, including variants with printed antenna, uFI connector, ETSI 10-dbm mode PA/LNA, and an FCC 20-dbm PA/LNA for long-range applications.
