NRF52820 in nRF52 Family
The nRF52820, developed by Nordic Semiconductor, is a high-performance multiprotocol SoC belonging to the nRF52 series. It is designed to provide a mid-range solution that bridges the gap between basic Bluetooth LE chips and high-end wireless processors. Built around an Arm Cortex-M4 processor, it supports Bluetooth 5.3, Direction Finding, High Throughput 2 Mbps, and Long Range, alongside Thread, Zigbee, and proprietary 2.4 GHz protocols, making it a versatile choice for cost-sensitive yet feature-rich wireless designs.
Variants in This Sub-Family
The nRF52820 family is primarily distinguished by its packaging and temperature grading. While the core architecture remains consistent with 256 KB Flash and 32 KB RAM, variants like the QDAA-R specify the 40-pin 5x5 mm QFN package. Some variants may be qualified for extended industrial temperature ranges up to 105°C, suitable for demanding environments such as industrial lighting and outdoor sensors.
