Design Notes
The STM32H735RGV6 requires a clean power supply. Use a 100 nF decoupling capacitor on each VDD pin and a 4.7 uF capacitor on the VDDA pin. For the core voltage (VDDCORE), use the internal LDO or an external SMPS to generate 1.2V. Ensure the power supply can handle the peak current during flash programming and high-speed operation.
For the LQFP64 package, use a 4-layer PCB with a solid ground plane. Place the decoupling capacitors as close to the power pins as possible. Route high-speed signals (Ethernet, USB) with controlled impedance and keep them away from noisy traces. Use a crystal oscillator with load capacitors as specified in the datasheet.
The LQFP64 package has a thermal resistance (theta_JA) of approximately 45Β°C/W. For high-power applications, ensure adequate airflow or a heatsink. Monitor the junction temperature to stay within the operating range. Use the internal temperature sensor to measure the die temperature in real-time.
