Design Notes
Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin, and add a 4.7uF bulk capacitor per supply domain. Connect VDDA to a clean analog supply through a ferrite bead and add a 1uF capacitor to VSSA. Ensure VREF+ is connected to a stable reference voltage (e.g., 3.3V) for accurate ADC readings. The device operates from 1.7V to 3.6V, so verify all peripherals are compatible with the chosen supply voltage.
For the HSE crystal oscillator, place the crystal and load capacitors close to the OSC_IN/OSC_OUT pins (PF0/PF1) and keep the trace lengths short and symmetrical. Use a ground plane around the oscillator area to minimize noise. For the USB interface, route the D+ and D- lines as a differential pair with controlled impedance (90 ohms) and place a 22-ohm series resistor on each line. Keep the SWD interface traces short for reliable debugging.
Do not leave the BOOT0 pin floating; connect it to ground through a 10k resistor for normal boot from Flash. Ensure the NRST pin has a 100nF capacitor to ground for reliable reset. When using low-power modes, configure all unused GPIOs as analog inputs to minimize leakage current. Also, verify that the supply voltage does not exceed 3.6V to avoid damaging the device.
