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
