Electrical characteristics

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.

1. Guaranteed by design.
2. Measured from 10% to 90% of the data signal. For more detailed informations, please refer to USB
Specification - Chapter 7 (version 2.0).
3. No external termination series resistors are required on DP (D+) and DM (D-) pins since the matching
impedance is included in the embedded driver.
