USB characteristics

The STM32L475xx USB interface is fully compliant with the USB specification version 2.0

and is USB-IF certified (for Full-speed device operation).

CAN (controller area network) interface

Refer to Section 6.3.14: I/O port characteristics for more details on the input/output alternate

function characteristics (CAN_TX and CAN_RX).

1. The STM32L475xx USB functionality is ensured down to 2.7 V but not the full USB electrical characteristics

which are degraded in the 2.7-to-3.0 V voltage range.

2. Guaranteed by design.

3. No external termination series resistors are required on USB_DP (D+) and USB_DM (D-); the matching

impedance is already included in the embedded driver.
