設計ノート
Ensure proper decoupling of the VDD and VDDA pins with 100 nF capacitors placed as close as possible to the pins. Additionally, use a 4.7 uF capacitor on the main power supply. For the VDDA pin, a dedicated analog supply with a ferrite bead can reduce noise and improve ADC accuracy.
For the 100-pin LQFP package, ensure adequate thermal relief and a solid ground plane. The exposed pad (if present) should be soldered to the ground plane for better thermal performance. Keep high-speed traces short and avoid routing them near the crystal oscillator pins to minimize noise.
Do not exceed the absolute maximum ratings for supply voltage and I/O pins. Ensure the boot pins are configured correctly for the desired boot mode. When using the high-resolution timer, verify that the clock source is stable and meets the required accuracy. Also, be aware of the math accelerator's register configuration to avoid unexpected behavior.
