disappear. The following conditions VDDUSB must be respected:

â During the power-on phase (VDD < VDD_MIN), VDDUSB should be always lower

than VDD

â During the power-down phase (VDD < VDD_MIN), VDDUSB should be always lower

than VDD

â The VDDUSB rising and falling time rate specifications must be respected (see

Table 20 and Table 21)

â In operating mode phase, VDDUSB could be lower or higher than VDD:

- If USB (USB OTG_HS/OTG_FS) is used, the associated GPIOs powered by

VDDUSB are operating between VDDUSB_MIN and VDDUSB_MAX.

- The VDDUSB supply both USB transceiver (USB OTG_HS and USB OTG_FS). If

only one USB transceiver is used in the application, the GPIOs associated to the

other USB transceiver are still supplied by VDDUSB.

- If USB (USB OTG_HS/OTG_FS) is not used, the associated GPIOs powered by

VDDUSB are operating between VDD_MIN and VDD_MAX.
