1. All the voltages are measured from the local ground potential.

2. To be compliant with the USB 2.0 full-speed electrical specification, the USB_DP (D+) pin should be pulled

up with a 1.5 kΩ resistor to a 3.0-to-3.6 V voltage range.

3. The STM32F3xxx 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 VDD voltage range.

4. Guaranteed by design, not tested in production.

5. RL is the load connected on the USB drivers
