NRF52820-QDAA-R7
Overview
The NRF52820-QDAA-R7 is a high-performance multiprotocol SoC designed for ultra-low power wireless applications. Built on an Arm Cortex-M4 core running at 64 MHz, it supports Bluetooth 5.3, Thread, and Zigbee, while featuring a full-speed USB 2.0 interface and a wide supply voltage range up to 5.5V.
Why Choose This Part
This SoC offers a unique balance of high-end features like USB and 8dBm output power in a cost-optimized package with 256kB Flash and 32kB RAM. It enables single-crystal operation and includes an on-chip DC/DC regulator to minimize the external BOM for space-constrained designs.
Applications
