NXP introduces low power wireless microcontrollers

The JN516x family supports JenNet-IP, ZigBee Light Link, ZigBee Smart Energy, ZigBee Home Automation and RF4CE

By CBR Staff Writer

UK based semiconducter firm NXP Semiconductors has introduced JN516x family, new ultra-low-power wireless microcontrollers for JenNet-IP, ZigBee and other IEEE 802.15.4 applications.

The JN516x wireless microcontrollers are single-chip devices that integrates a 2.45-GHz radio and analogue peripherals with microcontroller functionality in a single die.

In addition, the single-chip devices also claims to support JenNet-IP, ZigBee Light Link, ZigBee Smart Energy, ZigBee Home Automation and RF4CE.

The JN516x family offers up to 256 kB of embedded flash, 4 kB of on-chip EEPROM and 32 kB of RAM on the JN5168 to support the new network stacks.

It also includes an in-packet antenna diversity, which allows systems to choose the best antenna on every packet received.

NXP Semiconductors Smart Home and Energy product line general manager Marcel Walgering said the JN5168 is a wireless microcontroller for the ‘Internet of Things’, suitable for applications ranging from smart lighting and home automation to building automation and wireless sensor networks.

"With extensive on-chip memory and RAM, design engineers can do more with a much lower bill of materials, while taking advantage of NXP’s expertise in a wide range of software stacks based on the 802.15.4 standard," Walgering said.

The JN516x wireless microcontroller family will include JN5161 for RF4CE and IEEE 802.15.4 applications with 64 kB flash, 8 kB RAM, 4 kB EEPROM.

Further the family includes JN5164 for JenNet-IP, ZigBee Home Automation and ZigBee Light Link applications with 160 kB flash, 32 kB RAM, 4 kB EEPROM.

It also incorporates JN5168 for ZigBee Smart Energy applications and JenNet-IP gateways with 256 kB flash, 32 kB RAM, 4 kB EEPROM.

Additionally, the JN516x wireless microcontroller family includes a single evaluation kit suitable for all stacks, new 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
