The nRF52810-CAAA-R7 is a Bluetooth Low Energy 5.0 SoC from Nordic Semiconductor with ARM Cortex-M4 at 64MHz, 192KB Flash, and 24KB RAM in QFN-48. The Cortex-M4 core with FPU executes BLE stack and application code. The 2.4GHz radio transceiver supports BLE 5.0 features including 2Mbps PHY and long-range (125kbps coded PHY). The radio uses a direct-conversion receiver with integrated LNA and a polar transmitter with +4dBm output power. The on-chip balun simplifies antenna matching. Power management includes a DC-DC converter that steps 1.8-3.6V VDD down to the 1.3V core voltage, reducing current consumption to 5.3mA in TX and 5.4mA in RX mode. EasyDMA peripherals allow SPI, TWI, and UART to transfer data without CPU intervention. The device enters system-off mode at 300nA with RAM retention.
