114 / 202 page  Electrical characteristics STM32F730x8 114/202 DS12536 Rev 2 USB OTG HS and USB OTG HS PHY current consumption The MCU is placed under the following conditions: • STM32 MCU is enumerated as a HID device. • fHCLK = 216 MHz (Scale 1 + over-drive ON), fHCLK = 168 MHz (Scale 2), fHCLK = 144 MHz (Scale 3) The given value is calculated by measuring the difference of current consumption in case: – USB is configured but no transfer is done. – USB is configured and there is a transmission on going. • Ambient operating temperature is 25 °C, VDD = VDDUSB = 3.3 V. 6.3.8 Wakeup time from low-power modes The wakeup times given in Table 37 are measured starting from the wakeup event trigger up to the first instruction executed by the CPU: • For Stop or Sleep modes: the wakeup event is WFE. • WKUP (PA0) pin is used to wakeup from Standby, Stop and Sleep modes. All timings are derived from tests performed under ambient temperature and VDD=3.3 V. Table 36.
