Ghi chú thiết kế

Decouple every required MCU supply rail close to its associated pins, using the capacitor values and placement guidance in the official STM32F103xE datasheet. Keep analog and digital return paths controlled, provide a clean reset and clock path, and account for the transient current required by USB and CAN transceiver operation. The verified data confirms USB and CAN support but does not provide the complete power-tree values, so do not infer those values from this summary.

Route USB and CAN interfaces with short, controlled traces and provide the external transceivers specified by the selected interface architecture. Keep switching-regulator loops and high-current motor traces away from ADC inputs and communication lines. The 100-pin LQFP package requires careful fanout and decoupling placement; confirm the land pattern, pin numbering, and exposed thermal or electrical requirements from the official mechanical documentation before release.

Do not treat a related STM32F103 or cross-brand MCU as an automatic drop-in replacement. Check exact suffix, package, memory size, temperature grade, clock tree, peripheral multiplexing, USB and CAN electrical requirements, startup behavior, and firmware dependencies. The supplied cross-reference sources describe candidates such as GD32F103 and AT32F403A, but the data does not provide enough verified detail to approve production substitution without engineering validation.
