Based on the nRF52 Series architecture and compatible with the existing nRF52, nRF51, and nRF24 products, the ultra-low power nRF52840 SoC is one of the only single-chip SoCs on the market to offer simultaneous Bluetooth® 5 and Thread support, with Zigbee® support coming soon.
The nRF52840 SoC builds on the architecture of the existing nRF52 Series of SoCs to support complex Bluetooth low energy and other low-power wireless applications. The nRF52840 SoC employs a 64 MHz, 32-bit Arm® Cortex®-M4F processor, plus a CPU with 1 Mbyte of flash and 256 Kbytes of RAM, floating point unit, and digital signal processor (DSP) performance. The SoC also incorporates Arm TrustZone CryptoCell-310 cryptographic accelerator for best-in-class security.
The nRF52840 SoC 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 (2 Mbps) compared with the Bluetooth low energy implementation of Bluetooth 4.2. In addition to Bluetooth 5 support, the nRF52840 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.
The SoC is ideal for wireless Internet of Things (IoT) applications, including advanced wearables, virtual reality (VR) and augmented reality (AR), high-performance HID controllers, smart home products, and connected industrial devices.
