Hi, I've just got the STM32H723ZG Nucleo board and I'm trying to set up a High-Speed 480mbps data transmission. Do I need to buy an external PHY or does the model already support High-Speed USB communication?

As I recollect the USB connection is to the USB_FS side PA12/PA13
The USB_HS side needs an external PHY via ULPI.
The ST-LINK/V3 is implemented with an STM32F723 which doesn't need a PHY

It needs an external PHY such as USB3300 for high-speed USB.
Edit: in addition to what @Tesla DeLorean wrote above, the STM32H7S3x8 STM32H7S7x8 also has an internal high speed PHY.

Are there any other non-H7 models with 2 ADC channels and an embedded High-Speed PHY?

Besides the ones @Tesla DeLorean listed in the F7 series? I don't think so.
