Design Notes
The STM32H747BGT6 requires a stable power supply. Use a 100nF decoupling capacitor on each VDD pin and a 4.7uF capacitor on the VCAP pins. The internal voltage regulator needs an external capacitor (typically 2.2uF) on VCAP1 and VCAP2. Ensure the power supply can handle the peak current of up to 300 mA during high-speed operation.
For the LQFP-144 package, ensure proper grounding and thermal vias under the exposed pad (if present). Keep high-speed signal traces short and use impedance-controlled routing for Ethernet and USB lines. Place the crystal oscillator close to the OSC pins and add load capacitors as specified in the datasheet.
Avoid exceeding the absolute maximum ratings, especially on the power supply pins. Ensure the boot pins are configured correctly to avoid unexpected boot modes. When using the dual-core architecture, properly configure the memory protection unit (MPU) to prevent core interference. Also, note that the STM32H747BGT6 requires a specific power-up sequence; refer to the datasheet for details.
Compliance Information
