Inconsistent pin numbering

Hi,

We are working on a board with the STM32H7S7Z8J6 in a BG144 package.

We use cubemx to create the correct pinout for this part, but we see the datasheet has different pinout then the CubeMX tool. Is this a bug in CubeMX?

Hello @leddel32

There is not any issue. The Figure 7 of the DS14359 refer to the STM32H7S3Z8J6. The figure of the STM32H7S7Z8J6 is the figure 9 (same package but the STM32H7S7Z8J6 is clasified as GFx MCU. You can see this in table 2 of the datasheet).

Best Regards.

You are right. We were looking at figure 7 instead of figure 9.

Thank you for your answer.
