NRF52840-QIAA-R7

NRF52840-QIAA-R7 is a multiprotocol Bluetooth 5.4 SoC supporting Bluetooth low energy. It meets the challenges of sophisticated applications that need protocol concurrency and a rich and varied set of peripherals and features. It offers generous memory availability for both flash and RAM, which are prerequisites for such demanding applications. It is fully multiprotocol capable with full protocol concurrency. It has protocol support for Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4GHz proprietary stacks. It is built around the 32-bit ARM® Cortex™-M4 CPU with floating point unit running at 64MHz. It has NFC-A Tag for use in simplified pairing and payment solutions. The ARM TrustZone® CryptoCell cryptographic unit is included on-chip and brings an extensive range of cryptographic options that execute highly efficiently independent of the CPU.
