28 / 226 page  Functional overview STM32F732xx STM32F733xx 28/226 DS11854 Rev 6 Figure 7. VDDUSB connected to VDD power supply Figure 8. VDDUSB connected to external power supply On the STM32F7x3xx devices, the USB OTG HS subsystem uses one or two additional power supply pins depending on the package: • The VDD12OTGHS pin is the output of PHY HS regulator (1.2 V). An external capacitor of 2.2 µF must be connected on the VDD12OTGHS pin. • On the LQFP100 only, a second power pin VDDPHYHS is used to supply the USB OTG PHY HS and associated GPIOs.The VDDPHYHS follows the same rules provided for the VDDUSB power pin.
