I am going to design a schematic with STM32H723. I need the STM32h723 reference schematic for the eMMC. There is no eMMC schematic for the STM32h723 on the website. Can I get a reference schematic for this?

They wire up like an SDMMC, should use series resistors.

Look at STM32H745I-DISCO schematic ​

Thank you very much.

I would be grateful if you could tell me one more thing.

Does USB HS connection need to use PHY IC with ULPI interface?

USB HS peripheral in STM32 contains a built-in FS PHY, so if you are OK with communicating at FS (12MBit/s raw data rate), you don't need an external PHY.

Hello @DHRyu​,

You can check the schematic of the Nucleo-H723, sheet 5 you can find out the SDMMC wiring and schematic of STM32H745I-DISCO for the eMMC.

It would be better to enter a new post for a new question to adhere to ST Community guidelines.

As referenced in Datasheet, section 3.43 Universal serial bus on-the-go high-speed (OTG_HS) 

When using the USB OTG_HS interface in HS mode, an external PHY device connected to the ULPI is required.
