Electrical characteristics
STM32L4P5xx
246/311
DS12903 Rev 2
Note:
When VBUS sensing feature is enabled, PA9 should be left at its default state (floating
input), not as alternate function. A typical 200 μA current consumption of the sensing block
(current to voltage conversion to determine the different sessions) can be observed on PA9
when the feature is enabled.
Figure 47. USB OTG timings – definition of data signal rise and fall time
2. The STM32L45xx USB OTG full speed transceiver functionality is ensured down to 2.7 V but not the full
USB full speed electrical characteristics which are degraded in the 2.7-to-3.0 V VDD voltage range.
3. Guaranteed by design.
4. RL is the load connected on the USB OTG full speed drivers.
