Design Notes

The STM32H753BGT6 requires a stable power supply. Use a 100 nF decoupling capacitor on each VDD pin and a 4.7 uF bulk capacitor on the main supply. The VCAP pins require a 2.2 uF capacitor to ground for the internal voltage regulator. Ensure the supply voltage is within 1.62V to 3.6V.

For the LQFP-144 package, ensure proper grounding and thermal relief. Use a solid ground plane and place vias near the ground pins to minimize inductance. The exposed pad (if present) should be soldered to the ground plane for better thermal performance.

Do not leave unused pins floating; configure them as analog inputs or outputs to avoid excessive current consumption. Ensure the boot pins (BOOT0, BOOT1) are set correctly for the desired boot mode. The NRST pin should have a 100 nF capacitor to ground for reliable reset.
