N51422 datasheet pinout


The nRF51422 is a powerful, highly flexible multi-protocol SoC ideally suited for ANT and Bluetooth® low energy (previously called Bluetooth Smart) ultra low-power wireless applications. The nRF51422 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB/128kB flash + 32kB/16kB RAM. The embedded 2.4 GHz transceiver supports both Bluetooth low energy as well as the Nordic Gazell protocol stack which is on air compatible with the nRF24L series products from Nordic Semiconductor.

nRF51422 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 like 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 pinout location and function.
