72 MHz Cortex-M4 with rich analog — field integration note
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. It carries a 22-channel 12-bit ADC and a 2-channel 12-bit DAC — enough analog front-end for a multi-sensor motor drive or a three-phase inverter feedback loop without an external ADC. 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 -40°C to 85°C rating covers outdoor telecom cabinets and factory-floor enclosures without a heater.
