Nordic Semiconductor nRF52833-QIAA-R7, System-On-Chip for Industrial, 42-Pin QFN73

The nRF52833 is a general-purpose multiprotocol SoC with a Bluetooth 5.1 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.
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.
