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

2. The STM32F405xx and STM32F407xx USB OTG FS functionality is ensured down to 2.7 V but not the full

USB OTG FS 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
