Multi-protocol Bluetooth SoC supports Thread

March 14, 2017 // By Julien Happich
Nordic Semiconductor has launched its first Thread networking solution with the release of its nRF5 SDK for Thread that is designed to utilize the IEEE 802.15.4 PHY support introduced on Nordic's latest nRF52840 multi-protocol Bluetooth low energy SoC.

In addition, the Nordic nRF5 SDK for Thread also adds a unique Device-Firmware-Update (DFU)-over-Thread network feature like the Over-The-Air (OTA) DFU feature employed in other existing Nordic SDKs and chips.

With 256kB of RAM and 1MB of Flash memory, the nRF52840 not only runs both the Thread and Bluetooth low energy protocol stacks from a single chip, it is able to run the Thread protocol at accelerated processing speeds by using its built-in ARM CryptoCell-310 cryptographic accelerator to run the Thread security algorithms.

Other features of the Nordic nRF5 SDK for Thread include a pre-built OpenThread stack for the Nordic nRF52840 SoC; examples of all the different Thread roles; support for an OpenThread network co-processor; a CoAP application layer example; border router and cloud connectivity example; and a range of PC tools including a Thread topology monitor.

The Nordic nRF5 SDK for Thread is now available in Alpha release with full production scheduled for Q4 2017, aligning with the full production of the Nordic nRF52840 SoC.
