設計說明
Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, place a 4.7uF capacitor on the main VDD rail. The VDDA pin requires a dedicated 1uF capacitor to ground for analog performance. For the VBAT pin, connect a 100nF capacitor if using a backup battery. Ensure the power supply can handle the peak current of the MCU, which can be up to 200mA at 280MHz.
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 the crystal and load capacitors close to the OSC_IN/OSC_OUT pins and avoid routing other signals nearby. Use a solid ground plane under the MCU to reduce noise.
Ensure the BOOT0 pin is correctly configured to boot from flash. If using external memory via FMC, verify the timing parameters in the reference manual. Do not exceed the absolute maximum ratings for supply voltage (3.6V) and I/O pins (VDD+0.3V). When using the ADC, ensure the sampling time is sufficient for the source impedance. For low-power modes, configure the RTC and wakeup sources correctly to avoid unexpected resets.
