nRF51422System on Chip

Bluetooth Low Energy, ANT and 2.4 GHz SoC

The nRF51422 SoC is a general purpose, ultra-low power SoC ideally suited for ANT, Bluetooth® Low Energy and 2.4 GHz proprietary wireless applications. It is built around the 32-bit ARM® Cortex™-M0 CPU with 256/128 KB flash and 32/16 KB RAM. The flexible 2.4 GHz radio supports Bluetooth Low Energy, ANT and 2.4 GHz proprietary protocols, such as Gazell.

It incorporates a rich selection of analog and digital peripherals that can interact directly without CPU intervention through the Programmable Peripheral Interconnect (PPI) system. Flexible GPIOs enables you to connect digital interfaces like SPI Master/slave, TWI Master and UART to any of the 31 GPIOs on the device.
