nRF52833 System on Chip

105°C qualified Bluetooth 5.4 SoC supporting Bluetooth Low Energy, Bluetooth mesh, NFC, Thread and Zigbee

The nRF52833 is a general-purpose multiprotocol SoC with a Bluetooth Direction Finding capable radio, qualified for operation at an extended temperature range of -40°C to 105°C. It is the 5th addition to the industry leading nRF52 Series and is built around a 64 MHz Arm Cortex-M4 with FPU, and has 512 KB flash and 128 KB RAM memory available for higher value applications. 

The extended 105°C temperature qualification, coupled with 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. A 1:4 RAM to Flash ratio and +8 dBm output power make the nRF52833 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, and has a 1.7 V to 5.5 V supply voltage range, which enables powering the device from rechargeable batteries or over USB. The two-stage LDO regulator and a DC-DC converter, together with the automated power management system help deliver low power numbers even in more advanced applications.
