About the pins and pin descriptions of the STM32H7S3A8I6

[Woongi]

 Hello, I have a question about STM32H7S3A8I6 MCU.

https://www.st.com/resource/en/application_note/an5935-getting-started-with-stm32h7rx7sx-mcus-hardware-development-stmicroelectronics.pdf

Looking at Table 2 of the description in the PDF above, for graphics, STM32H7S3xx specifies GPU2D as N and GFXMMU as Y.

https://www.st.com/resource/en/datasheet/stm32h7s3a8.pdf

Looking at Table 21 in the following PDF, there are UFBGA 169 SMPS GFx and UFBGA 169SMPS GP. Can I look at the pin number with GFx?

and Is the library in the photo for the STM32H7S3A8I6 MCU?

The correct pinout for STM32H7S3A8I6 is Figure 8. UFBGA169 SMPS which lines up with UFBGA169 SMPS GP in Table 21.

@TDK  Thank you. Could you explain why? Or share some detailed documentation.

The package has two dies, "GP" and "GFx", as do several other packages for that family. These have nothing to do directly with GPU2D or GFXMMU.

From the picture I showed in my previous reply, one can see that STM32H73S is a GP die, so that's what it lines up with.
