Table 44.
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 USBDP (D+) pin should be pulled
3. The STM32F103xx USB functionality is ensured down to 2.7 V but not the full USB electrical
4. Guaranteed by design, not tested in production.
5. R
