Nordic’s nRF52840 multiprotocol SoC is Nordic’s most advanced ultra low power wireless solution. The SoC supports complex Bluetooth LE and other low-power wireless applications that were previously not possible with a single-chip solution. The nRF52840 is Bluetooth 5-, Thread 1.1-, and Zigbee PRO (R21) and Green Power proxy specification-certified and its Dynamic Multiprotocol feature uniquely supports concurrent wireless connectivity of the protocols. The SoC combines the Arm processor with a 2.4GHz multiprotocol radio. The chip supports all the features of Bluetooth 5 (including 4x the range or 2x the raw data bandwidth (2Mbps) compared with Bluetooth 4.2). Designed to address the inherent security challenges brought by the IoT, the nRF52840 SoC incorporates the Arm CryptoCell-310 cryptographic accelerator, offering best-in-class security.
The SoC is supplied with Nordic’s S140 SoftDevice, a Bluetooth 5-certified software protocol stack for building long range and high data Bluetooth LE applications. The S140 SoftDevice offers concurrent Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, and supports high throughput and long range modes as well as advertising extensions. OpenThread and Zigbee stacks are available through Nordic’s nRF5 Software Development Kit (SDK) for Thread and Zigbee.
“We selected the nRF52840 SoC for the MDBT50Q-RX dongle for its multiprotocol support and also Nordic’s nRF5 SDK for Mesh which together enable the widest possible application support for developers,” says Lyon Liu, Raytac Director. “On top of its powerful specifications, the addition of a USB interface provides developers with the most flexible and convenient interface for M2M IoT implementations.
“Nordic’s product roadmap is always one step ahead of the market. The company has foreseen the future of multiprotocol wireless applications and with the nRF52840 SoC has provided the best solution for IoT application development.”
