Nordic Semiconductor has launched the first two devices in its nRF51 series of ultra low power rf ics. The devices are said by the company to include a multiprotocol 2.4GHz radio and a 32bit ARM Cortex-M0 based processor.
The nRF51822 is a multiprotocol Bluetooth proprietary SoC operating at 2.4GHz, while the nRF51422 is billed as the first SoC to support ANT/ANT+. According to the company, the new parts feature power consumption of up to 50% less than similar devices, while offering rf link budget improvements of up to 9.5dB. Meanwhile, processing power is increased by an order of magnitude.
"We have worked closely with our most trusted customers for several years on the nRF51 series and are confident this latest product range
sets a new benchmark for Bluetooth low energy, ANT, and 2.4GHz rf proprietary ultra low power applications," said Thomas Embla Bonnerud, Nordic's director of product management.
Key features and benefits of the radio include: -92.5dB rx sensitivity in Bluetooth low energy mode; up to +4dBm output power in all modes; and peak currents of less than 10mA.
