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. The VDDA pin must be connected to a clean analog supply, and VREF+ should be decoupled with a 1uF capacitor. For best ADC performance, use a low-impedance source and consider adding a small RC filter on analog inputs.

For the LQFP64 package, ensure proper solder paste stencil design to avoid solder bridging. Use a 0.5mm pitch land pattern with a 0.3mm stencil aperture. Provide a solid ground plane under the device to reduce noise and improve thermal performance. Route high-speed signals away from analog inputs to minimize crosstalk.

Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs. Ensure the BOOT0 pin is properly tied to ground for normal boot from flash. When using the ADC, avoid switching digital I/O during conversion to prevent noise coupling. Also, verify that the supply voltage does not exceed 3.6V to prevent damage.
