The 22-channel 12-bit ADC and 2-channel 12-bit DAC support analog control loops. The 40 KB SRAM is enough for moderate data buffers and RTOS task stacks. ## Connectivity and peripherals — CANbus, USB, and the analog front end On the communication side, the STM32F303RCT6TR includes CANbus (2.0B active), USB (device mode), and multiple SPI/I²C/UART/USART interfaces. The DMA controller offloads data transfers for these peripherals, reducing CPU load. Internal POR and PWM timers are present, along with a watchdog timer. The oscillator is internal, so no external crystal is needed for basic operation, though an external clock can be used for tighter accuracy.","metaTitle":"STM32F303RCT6TR STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F303RCT6TR 32-bit ARM Cortex-M4 MCU, 72 MHz, 256 KB Flash, 40 KB RAM, 52 I/O, 64-LQFP.
