یادداشت‌های طراحی
The STM32H745VGT6 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 VDDA pin, use a 1uF capacitor and a ferrite bead to isolate analog noise. Ensure the VDD and VDDA supplies are within the 1.62V to 3.6V range.
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 EMI. For the crystal oscillator, place it close to the OSC pins and keep the load capacitors within 5mm to reduce stray capacitance.
The STM32H745VGT6 can dissipate significant power when running 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 125°C, so calculate the power dissipation and thermal resistance to ensure safe operation.
