Clarification: Which UFBGA169 pinout applies to STM32H7R7A8I6 part number?

[Sanjay27]

I need clarification regarding the correct pinout for the specific part number I am designing with: STM32H7R7A8I6.

I've noticed a discrepancy between the datasheet and the STM32CubeMX tool:

1. Datasheet: The document shows two options for the UFBGA169 package: Figure 8 (UFBGA169 SMPS pinout) and Figure 10 (UFBGA169 GFx with SMPS pinout).
2. STM32CubeMX: When I select the exact part number STM32H7R7A8I6 in Cube MX, it only displays the pin configuration that matches Figure 10 (UFBGA169 GFx with SMPS pinout).

Can you please confirm if the ordering code STM32H7R7A8I6 guarantees the GFX pin configuration (Figure 10)? I need this confirmation to ensure my PCB design is correct before finalizing my purchase and manufacturing.

Hello @Sanjay27 

I confirm that. According to the table 2 of the DS14360, All STM32H7R7 are GFx packages:

So, the STM32H7R7A8I6 is UFBGA169 GFx with SMPS.

Best Regards.

If STM32H7R7 only comes in GFx packages, why are there two UFBGA169 pinout tables in the datasheet?

The UFBGA169 SMPS is for the STM32H7R3A8I6 that is not GFx as you can see on the same table.

Best Regards.
