Hello,
Does the STM32U575CG/I (48-pin package) support USB communication, or is USB functionality only available on higher pin-count variants?
Thank you.

Hi @joaorego
All packages for this family support USB!
575 = STM32U575xx with OTG

But what about the USB supply voltage? Will it be sourced directly from VDD? Can I still supply VDD with a voltage lower than 3V?

USB requires 3.3 V power.

Hi @joaorego
As explained in the footnote of Table 150. OTG_FS characteristics (continued) in page 304,
USB functionality is ensured down to 2.7V, but some USB electrical characteristics are degraded in 2.7 to 3.0 V range.
