Next generation chip for ultra low power wireless solutions

Paul Boughton

The nRF52832 is the first of Nordic Semiconductor's nRF52 Series Systems-on-Chip. It 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 optimisation.

Achieving a 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 90 CoreMark/mA the SoC is up to 2X as power efficient as competing solutions.

The nRF52832 features: A category-first 64MHz ARM Cortex-M4F processor; 512kB Flash and 64kB RAM; a best-in-class ultra high performance, ultra low power multi-protocol Bluetooth Smart, ANT, and proprietary 2.4GHz radio with -96dB RX sensitivity, 5.5mA peak RX/TX currents, and an on-chip RF Balun.A unique fully-automatic power management system also makes achieving optimal power consumption easy for designers. Built on a cutting-edge 55nm process, the nRF52832 includes 6 x 6mm QFN and miniature 3.0 x 3.2mm CSP packaging options.

With a EEMBC 215 CoreMark score the nRF52832 delivers up to 60% more generic processing power - plus thanks to its on-chip ARM Cortex-M4F an additional 10X the Floating Point and 2X the DSP performance - compared to competing ARM Cortex-M0/M3 based Bluetooth Smart SoC solutions. And at 90 CoreMark/mA the SoC is up to 2X as power efficient as competing solutions.

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 ideal single-chip solution for wearables, human interface devices such as remote controllers, toys, smart home devices and appliances, and wireless charging.

The nRF52832's higher processor performance enables developers to make their products more attractive to consumers, including adding new features and improving the user experience.

The single-chip integration supports smaller products and a lower BOM. The increased power efficiency supports greater battery life and/or the use of smaller, lighter batteries, and makes the nRF52832 an ideal solution for applications powered by energy-harvesting. And the best-in-class radio performance supports up to 2X the connection reliability, robustness to interference, range, and data throughput--all minimising packet loss and tech support issues--plus greater network topology and protocol complexity, and advanced security features.
