30 / 193 page  Functional overview STM32WB55xx STM32WB35xx 30/193 DS11929 Rev 11 Figure 8. STM32WB35xx - Power supply overview 1. The USB transceiver is powered by VDDUSB, and the GPIOs associated with USB are powered by VDDUSB when USB alternate function (PA11 and PA12) is selected. When USB alternate function is not selected the GPIOs associated with USB are powered as standard GPIOs.
