Nordic Semiconductor nRF52811 BLUETOOTH® 5.2 Direction Finding SoCs

Nordic Semiconductor nRF52811 BLUETOOTH^® 5.2 Direction Finding SoCs take advantage of the latest and greatest features of Bluetooth 5.2. These features include Direction Finding, taking Bluetooth positioning to new heights. The devices are built around a 64MHz Arm® Cortex™-M4 CPU. A wide range of digital peripherals is available including PDM, PWM, UART, SPI, and TWI. Nordic Semiconductor nRF52811 also has a capable 12-bit ADC, and the exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system.

The radio in the nRF52811 SoC has comprehensive protocol capabilities, including Bluetooth 5.2 Directing Finding, all Bluetooth 5.2 features, 802.15.4, Thread, Zigbee, ANT, and 2.4GHz proprietary. The device has 4dBm TX power and has been optimized to offer the best RX sensitivity of all SoCs in the nRF52 Series:

• Bluetooth LE - Long Range: -104dBm
• Bluetooth LE - 1Mbps: -97dBm
• 802.15.4 (Thread/Zigbee): -101dBm
