51 GPIOs in the 64-LQFP package (10x10 mm). On-chip CAN, USB, SPI, I²C, UART, and IrDA cover most industrial fieldbus and HMI links.
For dual-sourcing resilience, the STM32F303CCT6 (48-pin, 256 KB Flash, -40 to 85 °C) is a lower-density sibling but shares the same core and peripheral set — useful as a second source on a different board variant, not a pin-drop replacement.
