Nordic Semiconductor has released the nRF52832, the first member of its latest nRF52 Series Systems-on-Chip (SoCs). The nRF52832 is a BluetoothSmart single-chip that is now entering mass production and includes a range of new, previously unannounced features.
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 low power 2.4 GHz multi-protocol radio, and fully automatic power optimization. Achieving a EEMBC 215 CoreMark the nRF52832 delivers up to 60 percent 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. This makes it an single-chip solution for wearables, human interface devices such as remote controllers, toys, smart home devices and appliances, and wireless charging.
