NRF52810-CAAA-R7
Overview
The nRF52810-CAAA-R7 is a high-performance, ultra-low power Bluetooth 5 SoC featuring a 64MHz ARM Cortex-M4 processor. It is designed as a cost-optimized entry point for the nRF52 series, providing a 2.4GHz radio with 192kB Flash and 24kB RAM in a compact 33-UFBGA WLCSP package. This device is specifically engineered for simple Bluetooth Low Energy applications requiring small physical footprints and minimal power consumption.
Why Choose This Part
This SoC balances cost and performance by integrating a powerful Cortex-M4 core with a versatile radio supporting -96dBm sensitivity. The single-crystal operation and EasyDMA-enabled interfaces like SPI and UART reduce system complexity and CPU overhead. Its wide 1.7V to 3.6V supply range and extremely low sleep currents make it ideal for coin-cell powered designs.
Applications
Key Specifications
Getting Started
Developers should use the nRF5 SDK or the nRF Connect SDK based on the Zephyr RTOS for application development. The nRF52-DK (PCA10040) is the recommended hardware platform for initial prototyping before migrating to the WLCSP-specific layout. Debugging is typically performed using a standard SWD interface with tools like the Segger J-Link.
