Design Notes

Decouple each VDD pin with a 100nF ceramic capacitor placed as close to the pin as possible. Additionally, connect a 4.7uF capacitor to the VDDA pin for analog supply filtering. Ensure the VREF+ pin is decoupled with a 1uF capacitor for accurate ADC conversions. The VBAT pin should be connected to a backup battery or tied to VDD if not used.

For the LQFP-64 package, ensure proper solder paste stencil design to avoid bridging between pins. Use a 0.5mm pitch footprint with appropriate pad sizes. Place the crystal oscillator (if used) close to the OSC_IN/OSC_OUT pins and keep the trace lengths short to minimize parasitic capacitance. Provide a solid ground plane under the MCU for EMI reduction.

Do not leave the BOOT0 pin floating; connect it to ground through a 10k resistor for normal boot from Flash. Ensure the NRST pin is pulled up with a 100nF capacitor to ground for reliable reset. When using the USB interface, add a 1.5k pull-up resistor on the USB_DP pin (PA12) for device detection. Also, verify that the supply voltage does not exceed 3.6V to prevent damage.
