New Bluetooth 5-Ready SoC Offers Increased Range, Bandwidth, & Security

Nordic Semiconductor’s new Bluetooth 5-ready nRF52840 SoC is well suited for smart home, advanced wearables, and industrial IoT applications. In addition to supporting 802.15.4, it’s capable of delivering Bluetooth low energy (BLE) wireless connectivity with up to 4× the range or 2× the raw data bandwidth (2 Mbps) compared with the BLE implementation of Bluetooth 4.2Nordic nRF52840

The nRF52840 SoC’s features, specs, and benefits:

  • Features a 64-MHz, 32-bit ARM Cortex M4F processor employed on Nordic’s nRF52832 SoC
  • A new radio architecture with on-chip PA boosting output power considerably, and extending the link budget for “whole house” applications, a doubling of flash memory to 1 MB, and a quadrupling of RAM memory to 256 KB
  • Support for Bluetooth 5, 802.15.4, ANT, and proprietary 2.4-GHz wireless technologies
  • A full-speed USB 2.0 controller
  • A host of new peripherals (many with EasyDMA) including a quad-SPI
  • Operates from power supplies above 5 V  (e.g., rechargeable battery power sources)
  • Incorporates the ARM CryptoCell-310 cryptographic accelerator offering best-in-class security for Cortex-M based SoCs. Extensive crypto ciphers and key generation and storage options are also available.

Nordic released the S140 SoftDevice and associated nRF5 SDK with support for Bluetooth 5 longer range and high throughput modes in December 2016. Engineering samples and development kits are now available. Production variants of the nRF52840 will be available in Q4 2017.
