Design Notes
The STM32H750IBT6 requires a stable power supply. Connect a 100 nF decoupling capacitor to each VDD pin and a 4.7 uF capacitor to the VCAP1 pin for the internal voltage regulator. Ensure the power supply can handle the peak current of up to 280 mA at 480 MHz. Use a low-impedance ground plane to minimize noise.
For high-speed operation at 480 MHz, pay careful attention to PCB layout. Keep traces short and use controlled impedance for high-speed interfaces like Ethernet and USB. Place the crystal oscillator close to the MCU and ensure proper grounding. Use a multi-layer PCB with dedicated power and ground planes to reduce EMI.
Do not forget to configure the boot pins correctly. The STM32H750IBT6 can boot from flash, SRAM, or system memory. Also, ensure the VCAP1 pin is connected to a capacitor as specified in the datasheet; otherwise, the internal voltage regulator may not start. Avoid exceeding the absolute maximum ratings for supply voltage (3.6V) and I/O pins.
