NORDIC nRF52833-QDAA-R

The nRF52833 is an ultra-low-power multiprotocol SoC qualified for operation at an extended temperature range of -40℃ to 105℃. Its feature set fulfills the requirements of professional lighting, advanced wearables, and higher value IoT applications. It supports Bluetooth LE, Bluetooth mesh, 802.15.4, Thread, Zigbee, and proprietary 2.4 GHz protocols. The nRF52833 is built around a 64 MHz Arm Cortex-M4 with floating-point unit (FPU). It has 512 KB flash and 128 KB RAM memory available for higher-value applications. The extended temperature range up to 105℃, a generous amount of memory, and dynamic multiprotocol support ensures the nRF52833 is an ideal device for a wide range of commercial and industrial applications, including professional lighting and asset tracking. The 1:4 RAM to Flash ratio and +8 dBm output power make the nRF52833 SoC suitable for advanced wearables or smart home applications where robust coverage is important. It includes a range of analog and digital interfaces such as NFC-A, ADC, Full-speed 12 Mbps USB 2.0, High-speed 32 MHz SPI, UART/SPI/TWI, PWM, I2S, and PDM. The 1.7 V to 5.5 V supply voltage range, enables powering the device from rechargeable batteries or over USB.
