256 KB Flash / 32 KB SRAM — firmware and data buffer sizing
The 256 KB Flash (256K x 8) provides enough code space for a full CANopen or Modbus stack plus application logic, while the 32 KB SRAM supports moderate data buffering and RTOS task stacks. The 2 KB EEPROM allows parameter storage without external serial memory — useful for calibration constants or node address retention across power cycles.
CANbus and USB OTG — network-ready for industrial and automotive buses
With CANbus, USB OTG, and multiple UART/SPI/I²C ports, this MCU can serve as a gateway node between a CAN-based sensor network and a USB-connected host, or as a multi-protocol bridge in a distributed control system. The 69 I/O pins provide ample GPIO for local sensing and actuation.
