Meet Bluetooth 5 SoC With 4x Range, 2x Bandwidth For IoT & Smart Home


Nordic Semiconductor has launched its Bluetooth 5 ready SoC with support for the longer range and higher throughput features of Bluetooth 5, enhancing its suitability for smart home, industrial wireless sensors, IoT, and advanced wearables for payments and medical sectors.

The new nRF52840 is designed to support the latest Bluetooth wireless technology Core Specification, Bluetooth 5, which delivers 4x range, 2x bandwidth, and security features.

The chip offers increased maximum output power (+8dBm), enabling it to support connectivity with up to 4x the range or 2x the raw data bandwidth (2Mbps) compared with the previous Bluetooth low energy implementation of Bluetooth 4.2, the firm claims.

In addition, the nRF52840 SoC also has support for IEEE 802.15.4 wireless technology capability, which forms the basis of smart home technologies such as ZigBee and Thread.


The nRF52840 SoC leverages the 64MHz, 32-bit ARM Cortex M4F processor employed on Nordic’s existing nRF52832 SoC, plus a CPU with ample generic processing power, Floating Point, and a DSP performance for most demanding wireless applications.

The chip offers more extensive Flash (1MB) and RAM memory (256kB) availability compared to the existing chip. It can also operate from power supplies above 5V such as re-chargeable battery power sources.

Leveraging an ARM CryptoCell-310 co-processor, the chip addresses the inherent security challenges faced in IoT applications. Nordic says extensive crypto ciphers and key generation and storage options are also available.

The firm also plans to release its S140 SoftDevice, a Bluetooth 5 compliant software stack with support for the long range and high throughput features of Bluetooth 5.

Industrial-grade eSIM Enables IoT and M2M

“With ARM Cryptocell hardware on-chip we are equipping developers with the very best-in-class hardware and software security options to build secure products. The Nordic Semiconductor nRF52840 SoC with its hardware enhancements, Bluetooth 5 range and bandwidth improvements, and IEEE 802.15.4 support, is the latest embodiment of that intention”, comments Thomas Bonnerud, Director of Strategy and Investor Relations at Nordic Semiconductor.

Nordic will release the S140 SoftDevice and associated nRF5 SDK upon ratification of the Bluetooth 5 standard by the Bluetooth SIG in early December. Samples and development kits will be available from December 6th.
