Catatan Desain

Ensure proper decoupling of VDD and VDDA pins. Place a 100nF ceramic capacitor as close as possible to each VDD pin, and a 1uF capacitor on VDDA. The VDDA pin must be connected to a clean analog supply to achieve the specified ADC performance. Use a ferrite bead between VDD and VDDA if the digital supply is noisy.

For the LQFP-48 package, use a 4-layer PCB with a solid ground plane. Route the crystal oscillator (OSC_IN/OSC_OUT) with short traces and keep them away from high-speed digital signals. Place the boot configuration resistors (BOOT0) with proper pull-up/pull-down to avoid unintended boot modes. Follow ST's layout guidelines in AN4666 for best EMC performance.

Do not leave unused I/O pins floating; configure them as outputs or enable internal pull-ups/pull-downs to reduce power consumption and avoid noise. Ensure the NRST pin has a 100nF capacitor to ground for reliable reset. 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.
