Key Differentiators

  • Higher clock speed than STM32H743 (vs STM32H743RGV6)
  • More flash memory than STM32H750 (vs STM32H750VBT6)
  • Same performance as GD32H757 with ST ecosystem (vs GD32H757VMT6)

Design Notes

The STM32H735RGV6 requires a clean power supply. Use a 100nF decoupling capacitor on each VDD pin and a 4.7uF bulk capacitor on the main supply. For the analog supply (VDDA), use a ferrite bead and a 1uF capacitor to filter noise. The core voltage (1.2V) can be generated internally via the LDO or externally via SMPS for better efficiency. Ensure the VCAP pin is connected to a 2.2uF capacitor as specified in the datasheet.

The VFQFPN68 package has a thermal resistance (theta_JA) of approximately 45Β°C/W. At 550 MHz with all peripherals active, power dissipation can reach 500mW, resulting in a temperature rise of 22.5Β°C above ambient. For high-power applications, ensure adequate airflow or a heatsink. The exposed pad should be soldered to a large copper area on the PCB to improve heat dissipation.

For the VFQFPN68 package, use a 0.5mm pitch land pattern. Ensure the exposed pad is connected to ground with multiple vias for thermal and electrical performance. Keep high-speed signals (Ethernet, USB) impedance-controlled and routed with proper ground planes. Place the crystal oscillator close to the OSC_IN/OSC_OUT pins with load capacitors as specified.
