Wireless ICs deliver 50% less power consumption

A new series of Ultra-Low Power wireless ICs from Nordic Semiconductor ASA could cut power use by 50 percent.

Nordic Semiconductor's nRF51 Series ULP 2.4GHz wireless SoCs feature higher performance, a lower power 2.4GHz multiprotocol radio and a 32bit ARM Cortex-M0 based processor.

These deliver up to 50 percent lower power consumption, RF link budget improvements of up to 9.5dB and over 10x more processing power compared to Nordic's previous generation of ULP wireless ICs.

The first two ICs to debut in the nRF51 Series are the nRF51822 and the nRF51422.

The nRF51822 is a multiprotocol Bluetooth low energy/2.4GHz proprietary RF SoC. While Nordic claims the nRF51422 is the world's first ANT/ANT+ SoC.

The nRF51 Series is suitable for developing applications employing any of the three main ULP wireless technologies: Bluetooth low energy; ANT / ANT+ and 2.4GHz proprietary RF.

Nordic's software architecture for Bluetooth low energy and ANT SoC solutions allows customers to develop their designs more easily using the familiar ARM Cortex programming environment. This major benefit is achieved by using a unique and powerful separation between protocol stack and user application code.

General availability is scheduled for early September 2012 and mass production is for 4Q12.
