  • Automotive grade option (vs STM8AF6288TCY)
  • Wide supply voltage range (vs STM8S207C8T6)

Design Notes

Decouple the VDD pins with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10uF bulk capacitor near the power input to handle transient currents. The STM8S208C8T6 operates from 2.95V to 5.5V, so ensure the supply voltage stays within this range under all load conditions.

For the 48-pin LQFP package, ensure proper solder paste stencil design to avoid solder bridging. The exposed pad (if present) should be connected to ground for thermal relief. Follow ST's layout guidelines for the SWIM interface to ensure reliable programming and debugging.

When using the CAN interface, an external CAN transceiver (e.g., TJA1050) is required. Ensure proper termination resistors (120 ohms) at both ends of the CAN bus. Also, the SWIM interface should be reserved for programming and debugging; do not use those pins for other functions in production.
