nRF52833 Multi-Protocol System-on-Chip (SoC) Nordic Semiconductor nRF52833 Multi-Protocol System-on-Chip (SoC) is optimized for a wide range of commercial and industrial applications, including professional lighting and asset tracking. The ultra-low power device is the fifth addition to the nRF52 Series and is built around a 64MHz Arm® Cortex™-M4 with FPU, and has 512KB flash and 128KB RAM memory available for higher value applications. nRF52833 features a BLUETOOTH® 5.2 Direction Finding capable radio, qualified for up to +105°C ambient temperature. Direction Finding enables positioning solutions to not only rely on the received signal strength indicator (RSSI), but also on the actual direction of a signal. This feature improves accuracy and increases application uses in this segment.
