Does STM32H723ZG support High-Speed USB data transfer without using the external PHY?

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.

Higher-end 'U5 (i.e. higher than 'U57x).
