NRF52832-QFAA-R

NRF52832-QFAA-R is a general-purpose multiprotocol SOC. It meets the challenges of a broad range of applications that need advanced Bluetooth® LE features, protocol concurrency and a rich and varied set of peripherals and features. In addition, it offers generous memory availability for both flash and RAM. The nRF52832 is multiprotocol capable with full protocol concurrency. It supports Bluetooth Low Energy, including the high-speed 2Mbps feature. Bluetooth mesh can be run concurrently with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT and 2.4GHz proprietary protocols are also supported. It is built around an Arm® Cortex™-M4 CPU with floating point unit running at 64MHz. Applications include internet of things (IoT), personal area networks, interactive entertainment devices, A4WP wireless chargers and devices, remote control toys, computer peripherals and I/O devices.
