The mass production version of the nRF52832 is certified to the latest Bluetooth v4.2 version of the Bluetooth specification and the Bluetooth software stack includes a new ‘LE secure connection’ capability that supports encrypted wireless communications. Device Firmware Upgrade (DFU) security has also been further enhanced.

In addition, there is a new flexible RAM scheme that allows developers to optimize how much memory is used by the software stack for any given configuration, and also concurrent multi Master-Slave network support. The latter feature allows, for example, a device such as smartwatch to act as both a hub to other wireless sensors and as a wireless peripheral to a smartphone at the same time.

The nRF52832 features a category-first 64MHz ARM Cortex-M4F processor, a best-in-class ultra high performance, low power 2.4GHz multi-protocol radio, and fully automatic power optimization. Achieving a EEMBC 215 CoreMark the nRF52832 delivers up to 60% more generic processing power than competing solutions and thanks to its ARM Cortex-M4F up to an additional 10X the Floating Point and 2X the DSP performance. And at 58 CoreMark/mA the nRF52832 is up to 2X as power efficient as competing solutions as well.

The nRF52832 also includes a full range of on-chip analog and digital peripherals for glueless interfacing to external components such as sensors, displays, touch controllers, LEDs, keypads, motors, digital microphones, and audio Codecs.
