The STM32L475RET6: The 51 I/O lines in the 64-LQFP package give enough pins for parallel sensor interfaces, display control, and actuator drive. The integrated CANbus and USB OTG support industrial and automotive communication stacks directly, while the QSPI interface can map external Flash or RAM into the memory space for firmware updates or data logging.
