nRF51822 Product Specification v3.3

Introduction

The nRF51822 chip is an ultra-low power 2.4 GHz wireless System on Chip (SoC) integrating the nRF51 Series

2.4 GHz transceiver, a 32 bit ARM® Cortex™-M0 CPU, flash memory, and analog and digital peripherals.

nRF51822 can support Bluetooth® low energy and a range of proprietary 2.4 GHz protocols, such as Gazell

from Nordic Semiconductor.

Fully qualified Bluetooth low energy stacks for nRF51822 are implemented in the S100 series of SoftDevices.

The S100 series of SoftDevices are available for free and can be downloaded and installed on nRF51822

independent of your own application code.
