The STM32F303RET6TR is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics' STM32F3 series, clocked at 72 MHz with 512 KB Flash and 80 KB RAM. The CANbus and LINbus interfaces let it sit on an automotive or industrial fieldbus backbone; USB is available for local data logging or firmware update via DFU.
The STM32F303RET6TR has an Active product status from STMicroelectronics.
The core runs at 72 MHz, based on the ARM Cortex-M4 with single-cycle multiply and hardware divide — enough for real-time control loops and moderate DSP.
