The Nordic nRF51422 is a powerful, highly flexible multi-protocol SoC ideally suited for ANT/ANT+, Bluetooth low energy and 2.4GHz proprietary ultra low-power wireless applications. The nRF51422 is built around a 32-bit ARM® Cortex™ M0 CPU with 256KB flash + 16KB RAM. The embedded 2.4GHz transceiver supports ANT as well as Bluetooth low energy and proprietary 2.4GHz operation, where the nRF51422 is on-air-compatible with the nRF24L and nRF24AP series products from Nordic Semiconductor. 

    

       

nRF51422 also incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interconnect (PPI) system. A flexible 31-pin GPIO mapping scheme allows I/O such as serial interfaces, PWM and quadrature demodulator to be mapped to any device pin as dictated by PCB requirements. This enables complete design flexibility associated with pin-out location and function.

   

nRF51422 requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8-3.6V, a direct 1.8V mode and a on chip DCDC buck converter giving a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enables nRF51422 to operate at radio peak currents below 10mA @ 3V supply (TX @ 0dBm & RX).

   

The nRF51422 is available in a 48-pin 6x6 QFN package.

nRF51 SDK provides extensive software support for both ANT and Bluetooth low energy applications.
