Nordic's nRF52840 brings Bluetooth 5, Bluetooth mesh, multiprotocol wireless support to IoT developers
March 29, 2018
In addition to being Bluetooth 5-certified, the multi-protocol SoC supports Bluetooth mesh, Thread, 802.15.4, ANT, and 2.4GHz proprietary protocols.
OSLO, NORWAY. Nordic Semiconductor has announced availability of its nRF52840 Bluetooth Low Energy (BLE) system on chip. In addition to being Bluetooth 5-certified, the multi-protocol SoC supports Bluetooth mesh, Thread, 802.15.4, ANT, and 2.4GHz proprietary protocols. The chips are also outfitted with a 32-bit Arm Cortex-M4F processor running at 64 MHz for general processing tasks, as well as an Arm CryptoCell-310 cryptographic accelerator.
The nRF52840 delivers the full benefits of Bluetooth 5, including 2 Mbps on-air raw data bandwidth, 4x range, 8x broadcasting capability with packet payloads of up to 251 bytes, and improved channel coexistence. It also supports concurrent Bluetooth 5 and Thread operation through a “Dynamic Multiprotocol” feature that enables simultaneous execution of Nordic’s S140 SoftDevice software stack and the OpenThread RF protocol stack.
The SoC is based on a radio architecture consisting of an on-chip +8 dBm power amplifier (PA), 1 MB Flash, 256 kB RAM, a full-speed USB 2.0 controller, and other peripherals such as a quad-SPI interface with EasyDMA. The chip can also operate from power supplies above 5V.
The nRF52840 release is accompanied by a new version of Nordic’s nRF5 software development kit (SDK), which includes full peripheral driver support for the SoC, an IPv6-over-Bluetooth LE adaptation layer (6LoWPAN), a complete Internet Protocol (IP) suite, and SEGGER’s Embedded Studio development software. A production-grade nRF5 SDK for Mesh tool is also available for Bluetooth mesh developers working with the nRF52840.
