The nRF52820 Bluetooth 5.2, multiprotocol SoC is the sixth addition to Nordic’s nRF52 Series and is intended to provide an ultra-low-power Bluetooth LE, Bluetooth mesh, Thread, Zigbee, and 2.4-GHz proprietary lower-end wireless connectivity solution. nRF52820 supports all the features of Bluetooth 5, 5.1, and 5.2 including Long Range and high-throughput 2 Mbps, Direction Finding, LE Power Control, and LE Isochronous Channels. The SoC also includes a Full Speed (12 Mbps) USB 2.0 interface.
The SoC has a 64-MHz 32-bit Arm Cortex-M4 processor with 256 KB Flash and 32 KB RAM. When paired with an application MCU, the nRF52820's fully-featured multiprotocol radio and +8 dBm output power allows it to act as a network processor for gateways and smart home applications. The nRF52820 is qualified for operation from -40 to 105 °C.
In addition to the main supply regulators, the USB peripheral in the nRF52820 has a dedicated regulator for converting the 5-V VBUS signal to the 3.3 V required for the USB signalling interface, negating a need for an external regulator.
The nRF52820 features up to 18 GPIOs, as well as a range of analog and digital interfaces including an analog comparator, SPI, UART, TWI, and QDEC. The supply voltage ranges from 1.7 to 5.5-V, allowing the nRF52820 to be powered by coin-cells and rechargeable batteries.
