Name :
nRF51822-QFAA Multiprotocol Bluetooth® 4.0 low energy/2.4 GHz RF SoC
Introduction
nRF51822 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.


Description

        nRF51822 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.

         nRF51822 is available in different package and memory variants. When data in this product specification does not apply to all variants, those variants it does apply to will be clearly stated. An example of a variant name is nRF51822-QFAA. If no variant name is stated, or if just nRF51822 is used, the data will apply to all versions of nRF51822.
