Design Notes

Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the pin. Add a 4.7 uF bulk capacitor for the digital supply. For VDDA, use a dedicated 1 uF capacitor to ground to ensure analog performance. The supply voltage range is 1.62V to 3.6V, so ensure the power supply is stable and within this range.

For high-speed interfaces like Ethernet and USB, maintain controlled impedance traces (e.g., 90 ohms differential for USB). Keep traces short and avoid vias where possible. Use a solid ground plane to minimize noise. For the crystal oscillator pins, place the crystal and load capacitors close to the MCU and keep the traces short to reduce parasitic capacitance.

Ensure the BOOT0 pin is correctly configured for the desired boot mode. For debugging, connect SWDIO and SWCLK pins with pull-up resistors. Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs. Also, verify that the VDDA pin is connected to a clean analog supply, as noise on VDDA can degrade ADC performance.
