The nRF52832 is a multi-protocol SoC for Bluetooth and 2.4 GHz ultra low-power wireless applications. It consists of an integrated 32-bit ARM Cortex-M4F CPU with 512kB + 64kB RAM. The embedded 2.4GHz transceiver supports Bluetooth Smart, ANT and proprietary 2.4 GHz protocol stack. It supports a NFC tag on chip. Out-of-Band (OOB) pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link. The nRF52832 is available in a 6x6 mm QFN48 package.
