STM32G4 series - I2C2 SDA and SMBA in datasheet switched?

[Loebl]

I just noticed the following:

In the datasheets for the G473 and G483 the pin table and alternate function table disagree which pin has the I2C2_SMBA and I2C2_SDA function.

The pin table claims PA10 is I2C2_SMBA and PA8 is I2C2_SDA. The alternate function table claims PA8 is I2C2_SMBA and PA10 is I2C2_SDA.

From experiments it seems the pin table is correct.

Can someone confirm which is the correct alternate function?

Now that I was comparing both columns: it also seems I2C3_SCL is placed differently in both tables: the pin table has it on PA8, the alternate function table on PA10.

EDIT 2023-09-04: for completeness, because I initially forgot:

• STM32G483xE DS12997 Rev 4 Nov 2021
• STM32G473xE DS12712 Rev 4 Nov 2021

Hello @Loebl 

I confirm the problem of  I2C2_SDA and I2C2_SMBA in the G483. But  G473, this problem doesn't exist.

For the I2C3_SCL problem, I can confirm it for both G4 models.

Best regards.
