The single-chip Bluetooth low energy nRF52840 System-on-Chip (SoC) from Nordic Semiconductor includes support for new long range and high throughput features of the soon-to-be-released Bluetooth 5 specification, plus radio support for IEEE 802.15.4, more extensive Flash and RAM memory availability, and a new radio hardware architecture with increased output power and link budget.

Compliance with the Bluetooth 5 specification, coupled with increased maximum output power, enables the nRF52840 SoC to deliver Bluetooth low energy wireless connectivity with up to 4x the range or 2x the raw data bandwidth (2Mbps) compared with the Bluetooth low energy implementation of Bluetooth 4.2.

The nRF52840 SoC’s support for 802.15.4 wireless technology extends the product’s capability as an interoperable foundation technology for IoT, smart home, or industrial sensor wireless networks using several different wireless technologies including ZigBee and Thread.

The nRF52840 SoC employs the proven 64MHz, 32-bit ARM Cortex M4F processor employed on Nordic’s nRF52832 SoC, plus a CPU with ample generic processing power, Floating Point, and DSP performance, to meet the demands of even the most demanding wireless applications.

Designed to address the inherent security challenges that are faced in IoT, the nRF52840 SoC 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.

The introduction of the nRF52840 SoC will be accompanied by the release of the S140 SoftDevice, Nordic’s latest addition to its family of RF protocol software ‘stacks’.
