nRF52832

Overview

Built around a 32-bit ARM® Cortex™-M4F CPU with 512kB + 64kB RAM, Nordic Semiconductor's nRF52832 multiprotocol SoC offers record breaking performance to the application developer. The nRF52832 incorporates powerful processing with floating point capability, power efficiency through a system of automated and adaptive power management features, a broad suite of analog and digital peripherals, and on-chip NFC™-A tag support.

In collaboration with Nordic Semiconductor, ANT Wireless provides two ANT stacks targeted exclusively for the nRF52 Series SoCs:

  • S212 ANT SoftDevice
  • S332 Concurrent ANT/Bluetooth® Low Energy (BLE) SoftDevice

See the SoftDevices tab below to access the evaluation protocol stacks provided by ANT Wireless. 

SoftDevices Manufacturer's Product Page

The nRF52832 supports programmable SoftDevice protocol stacks for easy access to new features and improvements. ANT Wireless makes ANT available for the nRF52832 with the S212 ANT SoftDevice and the S332 ANT/BLE SoftDevice. 

SoftDevice Configuration Benefits
