The nRF52840 multi-protocol system-on-chip (SoC) from Nordic Semiconductor is in stock at Mouser Electronics. Based on Nordic’s nRF52 Series architecture and compatible with Nordic’s existing nRF52 Series, nRF51 Series, and nRF24 Series products, the ultra-low power SoC is one of the only single-chip solutions on the market to offer simultaneous Bluetooth 5 and Thread support, with Zigbee support coming soon.

The SoC supports complex Bluetooth low energy and other low-power wireless applications. It employs a 64MHz, 32-bit Arm Cortex-M4F processor, plus a CPU with 1Mbyte of flash and 256Kbytes of RAM, floating point unit, and digital signal processor (DSP) performance.

The SoC also incorporates Arm TrustZone CryptoCell-310 cryptographic accelerator for security.

The device complies with the Bluetooth 5 specification, which, coupled with increased maximum output power, enables the device to deliver Bluetooth low energy wireless connectivity with up to four times the range or up to twice the raw data bandwidth (2Mbps) compared with the Bluetooth low energy implementation of Bluetooth 4.2.

In addition to Bluetooth 5 support, the SoC includes NFC-A tag support plus IEEE 802.15.4 capabilities for Zigbee- and Thread-based smart home technologies or as a Network Adaptation Layer with 6LoWPAN and standard internet protocols.

The SoC is supported by the Nordic nRF52840 Preview Development Kit, which includes an onboard nRF52840 SoC and four user-programmable buttons and LEDs, is hardware compatible with the Arduino Uno R3-based shields, and features connector pins for all inputs and outputs (I/O) and interfaces, including a dedicated connector for the included external NFC antenna.

Applications cover wireless Internet of Things (IoT), including advanced wearables, virtual reality (VR) and augmented reality (AR), high-performance HID controllers, smart home products, and connected industrial devices.
