NRF51422-QFAC-R7

NRF51422-QFAC-R7 is a multiprotocol Bluetooth low energy and ANT/ANT+ and 2.4GHz proprietary system-on-chip. It uses the 32-bit ARM Cortex M0 MCU, together with extensive flash availability. Code density and execution speed are considerably greater than for 8/16-bit platforms. The Programmable Peripheral Interconnect (PPI) system provides a 16-channel bus for direct and autonomous system peripheral communication without CPU intervention. The application includes Bluetooth low energy applications, wearables, beacons, accessories, smart home, ANT/ANT+ Sensor networks, wearable sensors, computer peripherals, CE remote controls for TV, STB and media systems, proximity and security alert tags, sports and fitness sensors, healthcare and lifestyle sensors, game controllers and computers, toys and electronic games, domestic/industrial control and data acquisition, intelligent domestic appliances.
