Nordic nRF52840 SoC brings most advanced multiprotocol IoT solution to market

Nordic Semiconductor today announces that its nRF52840 Bluetooth Low Energy (Bluetooth LE) System-on-Chip (SoC)-the high-end variant of Nordic’s nRF52 Series of class-leading, high-performance Bluetooth 5-certified SoCs-is now available in production volume for customers across the world. The nRF52840 accompanies the mid-range nRF52832 and baseline nRF52810 SoCs in Nordic Semiconductor nRF52 Series. With a wealth of features and peripherals the SoC offers the capabilities and flexibility to support a broad range of networked, connected products for wearables, gaming, VR/AR, and home- and industrial-IoT applications.

The full production volume launch of the nRF52840 SoC is accompanied by the production version of Nordic’s S140 SoftDevice (Nordic’s latest RF Bluetooth 5 (Bluetooth LE)-certified protocol software or ‘stack’), and a new version of Nordic’s nRF5 Software Development Kit (SDK), a production-ready development tool with full peripheral driver support for the nRF52840 SoC. Additionally, for developers building Bluetooth mesh applications, the nRF52840 is supported by the production-grade nRF5 SDK for Mesh.

The high-end nRF52840 SoC, based on Nordic’s proven nRF52 Series architecture, is the first single-chip solution to bring all the benefits of Bluetooth 5 to the market. The key advantages of Bluetooth 5 compared with previous implementations of the Bluetooth LE specification include: 2x on-air raw data bandwidth (2Mbps); 4x range; 8x broadcasting ability with advertising extensions that increase the advertising packet payload size to 251 bytes, and an improved channel coexistence algorithm.

In addition, the nRF52840 SoC is the only multiprotocol device on the market to offer concurrent Bluetooth 5 and Thread support. The capability is enabled by the SoC’s Bluetooth LE and Thread ‘Dynamic Multiprotocol’ feature which allows simultaneous support of the S140 SoftDevice and OpenThread RF protocol stack.

Engineers can commence developing designs with the nRF52840 SoC and S140 SoftDevice using the latest version of Nordic’s nRF5 SDK. The nRF5 SDK v15 is a production-ready development tool with full peripheral driver support for the nRF52840 SoC. In addition, the nRF5 SDK now incorporates the capabilities of the earlier nRF5 SDK for IoT including an IPv6 over Bluetooth LE adaptation layer (6LoWPAN) and a complete Internet Protocol (IP) Suite. The nRF5 SDK also includes SEGGER Microcontroller’s ‘Embedded Studio’, a complete all-in-one solution for managing, building, testing, and deploying embedded applications.

The nRF52840 SoC employs a 64MHz, 32-bit Arm® Cortex™ M4F processor which has ample generic processing power, Floating Point, and DSP performance to meet the demands of even the most challenging wireless applications.

The SoC features a new radio architecture with an +8 dBm on-chip PA; 1MB Flash and 256 kB RAM; full support for Bluetooth 5, 802.15.4 (including Thread), ANT, and proprietary 2.4GHz wireless technologies; a full speed USB 2.0 controller, and a host of peripherals (many with EasyDMA) including a quad-SPI interface. The nRF52840 can also operate from power supplies above 5V, such as re-chargeable battery power sources.

The SoC also incorporates an Arm® CryptoCell-310 cryptographic accelerator for best-in-class security for Cortex-M based SoCs. Extensive crypto ciphers and key generation and storage options are also available.

The S140 SoftDevice is an extensively-tested Bluetooth 5-certified software stack with full support for all the benefits of Bluetooth 5 in concurrent, multi-role operation.
