nRF52811 System on Chip

Bluetooth 5.4 SoC supporting Bluetooth Low Energy, Bluetooth Direction Finding and Thread

The nRF52811 is built around a 64 MHz Arm® Cortex™-M4 CPU, and has a range of digital peripherals and interfaces such as PDM, PWM, UART, SPI and TWI. It also has a capable 12-bit ADC. Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system. 

The nRF52811 SoC supports Bluetooth Low Energy, and is capable of Bluetooth Direction Finding in addition Long Range and 2 Mbps. Thread, and 2.4 GHz proprietary protocols are also supported. It has 4 dBm TX power and has been optimized to offer the best RX sensitivity of all SoCs in the nRF52 Series:

  • Bluetooth LE - Long Range: -104 dBm
  • Bluetooth LE - 1 Mbps: -97 dBm
  • Thread:       -101 dBm

The nRF52840 DK is the recommend development kit, emulating the nRF52811 SoC, and can be used as a starting point for development before moving over to a custom board. Please note that this development kit does not support Bluetooth Direction Finding.

The nRF52811 SoC comes in our smallest package, a 2.48x2.46 mm WLCSP package, together with two QFN packages. It is drop-in compatible with the nRF52810 SoC in all package variants:

  • 6x6 mm QFN48 with 32 GPIOs
  • 5x5 mm QFN32 with 17 GPIOs
  • 2.48x2.46 mm WLCSP32 with 15 GPIOs
