Notas de projeto
Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin. Additionally, connect a 4.7uF capacitor to the main VDD rail. For VDDA, use a 1uF capacitor and a 10nF capacitor in parallel to filter high-frequency noise. Ensure the ground connections are low-impedance to minimize voltage drops.
For the LQFP-48 package, use a 0.5mm pitch land pattern. Provide a solid ground plane under the MCU to reduce EMI and improve thermal performance. Route the crystal oscillator (if used) with short traces and keep them away from high-speed digital lines. Add a series resistor (e.g., 33 ohms) on the SWD clock line to reduce ringing.
Do not leave unused GPIO pins floating; configure them as analog inputs or outputs to reduce leakage current. Ensure the BOOT0 pin is properly pulled low for normal boot mode. When using the ADC, connect VDDA to a clean analog supply and add a ferrite bead to isolate it from digital noise. Also, verify that the NRST pin has a 100nF capacitor to ground for reliable reset.
