USB characteristics

The USB interface is fully compliant with the USB specification version 2.0 and is USB-IF

certified (for Full-speed device operation).

Driving high

and low

Ω

1. TA = -40 to 125 °C unless otherwise specified.

2. The STM32L412xx 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.

3. Guaranteed by design.

4. 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.
