NRF52832-QFAA-R [Nordic System On Chip] : Versatile BT 5.4 SoC Supporting BT Low Energy

The NRF52832-QFAA-R is a general-purpose multiprotocol SoC. It meets the challenges of a broad range of applications that need advanced BT® 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-QFAA-R is multiprotocol capable with full protocol concurrency. It supports BT Low Energy, including the high-speed 2 Mbps feature. BT mesh can be run concurrently with BT LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT and 2.4 GHz proprietary protocols are also supported.

It is built around an Arm® Cortex™-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag for use in simplified pairing and payment solutions. It has numerous digital peripherals and interfaces such as PDM and I2S for digital microphones and audio.

Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system.
