Note:

When VBUS sensing feature is enabled, PA9 should be left at their default state (floating

input), not as alternate function. A typical 200 µA current consumption of the embedded

sensing block (current to voltage conversion to determine the different sessions) can be

observed on PA9 when the feature is enabled.

CAN (controller area network) interface

Refer to Section 6.3.16: I/O port characteristics for more details on the input/output alternate

function characteristics (CANx_TX and CANx_RX).

2. The USB OTG FS 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, not tested in production.

4. RL is the load connected on the USB OTG FS drivers.
