The Nordic nRF52811 SoC includes a multiprotocol 2.4GHz radio (featuring 4dBm output power with -97dBm sensitivity (at 1Mbps in Bluetooth 5 mode)), 64MHz, 32-bit Arm® Cortex™ M4 processor, and 192kB Flash and 24kB RAM memory. The nRF52811 SoC also includes a wide range of analog and digital interfaces.

The nRF52811 SoC is an ideal connectivity chip for applications that feature a companion microprocessor. Examples include home and industry gateways that demand low power wireless support for Bluetooth 5, Thread, and Zigbee smart applications such as those used with smart light networks, HVAC, and security systems. The SoC is also a good choice for cost-constrained Bluetooth beacon applications requiring Bluetooth 5 technology’s extended range or employed as part of a Direction Finding system.
