设计说明
Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, place a 4.7uF capacitor at the main power input. For the VDDA pin, use a 1uF capacitor and a ferrite bead to isolate analog noise. Ensure the VDD and VDDA supplies are clean to avoid ADC and DAC performance degradation.
For high-speed interfaces like Ethernet and USB, maintain controlled impedance traces (e.g., 90 ohms differential for USB). Keep traces short and use ground planes to minimize EMI. For the crystal oscillator, place it close to the MCU and keep the load capacitors within 5mm. Use a solid ground plane under the MCU to reduce noise.
Ensure the BOOT0 pin is properly configured to boot from Flash. Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs to reduce power consumption. When using the ADC, ensure the sampling time is sufficient for the source impedance. Also, verify that the power supply can handle the peak current during Flash programming.
