Based on Nordic’s proven nRF52 Series architecture, the nRF52840 SoC is a single-chip solution for Bluetooth 5. The SoC offers bandwidth doubled to 2 Mbps, quadruples the range, an increased 251 byte advertising packet size and an improved channel coexistence algorithm. Nordic also claims that the nRF52840 SoC is the only on the market to offer concurrent Bluetooth 5 and Thread support through its BLE and Thread ‘Dynamic Multiprotocol’ feature.
The latest version of Nordic’s nRF5 SDK allows developers to immediately start on designs using the nRF52840 SoC and S140 SoftDevice stack. nRF5 SDK v15 is a production-ready with full peripheral driver support for the nRF52840. The SDK now supports features including IPv6 over BLE adaptation layer (6LoWPAN) and a complete IP Suite. Software development support is included through SEGGER Microcontroller’s ‘Embedded Studio’.
The nRF52840 is powered by a 64 MHz, 32-bit Arm Cortex M4F processor with floating point capability and DSP performance. It also has a new radio architecture with an +8 dBm on-chip PA, 1MB Flash and 256 kB RAM, 802.15.4 support (including Thread), ANT, and proprietary 2.4 GHz wireless technologies, full speed USB 2.0 controller and additional peripherals including a quad-SPI interface. The SoC also has an Arm CryptoCell-310 cryptographic accelerator for best-in-class security for Cortex-M based SoCs.
