Overview

The nRF52820 is a high-performance Bluetooth 5.3 SoC designed as a cost-optimized solution for multi-protocol wireless applications. Based on a 64 MHz Arm Cortex-M4 processor, it integrates 256 kB Flash and 32 kB RAM with a Full Speed USB 2.0 interface and support for Thread and Zigbee protocols. This device provides a balanced feature set for connected peripherals and ultra-low power wireless sensors.

Why Choose This Part

The nRF52820 offers a high link budget with -95 dBm sensitivity and up to +8 dBm output power, ensuring robust wireless range. Its wide supply voltage range from 1.7V to 5.5V allows for direct operation from USB power or Li-ion batteries without external regulators. The SoC achieves industry-leading power efficiency with a peak RX current of only 4.7 mA and a deep sleep mode consuming just 0.3 uA.

Applications

USB Dongles and Bridges
Utilizes the integrated Full Speed USB controller to bridge 802.15.4 or Bluetooth LE traffic to a host computer.
HID Peripherals

Getting Started

Development is best started with the nRF52833 DK, which can emulate the nRF52820 hardware. Use the Nordic nRF Connect SDK based on the Zephyr RTOS for software development. Debugging is performed via the standard SWD interface using a Segger J-Link or the onboard debugger of a Nordic development kit.
