Introduction

The nRF52810 SoC uses the same 100dBmlink budget 2.4GHz multi-protocol radio as the nRF52832 SoC and is equippedwith a 64MHzh 32-bit ARM Cortex-M4 MCU to meet demanding performance requirements;it uses the same hardware and software as other nRF52 series SoCs.Architecture, which means that migration between nRF52 series isstraightforward. At the same time, although the nRF52810 is a basic Bluetooth 5SoC, there are still many common peripherals available - compared to thenRF52832's 512kB flash and 64kB RAM, it integrates 196kB flash and 24kB RAM,enough to run typical high throughput, low-Cost application code and supportfor device firmware update (OTA-DFU) for target applications via over-the-airtechnology. In addition, the nRF52810 is compatible with the nRF52 DevelopmentKit (DK), and the application code compiled for the device is portable to allSoCs in the nRF52 family. Users can use the parallel multi-role S132 protocol stacksupporting 20 links and the nRF5 SDK when developing application software.
