Design Notes

The STM32H743BIT6 requires a stable power supply. Use a 100nF decoupling capacitor on each VDD pin and a 4.7uF bulk capacitor on the main supply. For the internal LDO, connect the VCAP pins to ground with a 2.2uF capacitor. Ensure the supply voltage is within 1.62V to 3.6V.

For high-speed interfaces like Ethernet and USB, maintain controlled impedance traces (e.g., 90 ohms differential for USB). Keep traces short and use ground planes to minimize noise. Place the crystal oscillator close to the OSC pins and add load capacitors as specified in the datasheet.

The STM32H743BIT6 can dissipate significant power at 480 MHz. Ensure adequate thermal management by providing a copper pour on the PCB and, if necessary, a heatsink. The maximum junction temperature is 125C, so calculate the thermal budget based on the application's power consumption.
