Design Notes
The STM32H747XIH6 requires a stable power supply with proper decoupling. Use a 100 nF capacitor on each VDD pin and a 4.7 uF bulk capacitor on the main supply. For high-speed operation, consider using a dedicated power plane and place decoupling capacitors close to the pins. The device supports multiple power domains (VDD, VDDA, VDDUSB), each requiring separate filtering.
For the TFBGA-240 package, ensure proper PCB layout with adequate via placement for thermal and electrical performance. Use a 4-layer or more PCB with dedicated ground and power planes. Route high-speed signals (Ethernet, USB) with controlled impedance and keep trace lengths matched. Place the crystal oscillator close to the OSC pins and provide a ground guard ring.
Avoid exceeding the absolute maximum ratings, especially on supply voltage (3.6V max). Ensure the boot configuration pins are set correctly to avoid unintended boot modes. When using the dual-core architecture, properly configure the interrupt priorities and shared peripherals to prevent conflicts. Also, note that the TFBGA-240 package requires careful soldering; use a reflow profile recommended by ST.
