STM32G473 I2C2 pinout mistake in Datasheet

[thomas23]

Hi,

I would like to make a new electronic design with the STM32G473, using I2C2.

But it seems there is a mistake in the datasheet regarding the pinout.

On pin description it says:

PA8 = I2C2 SDA

PA9 = I2C2 CLK

PA10 = I2C2 SMBA

Whereas on Alternate function it says:

PA8 = I2C2 SMBA

PA9 = I2C2 CLK

PA10 = I2C2 SDA

Which one is correct?

If I look on other similar MCUs, I think the second version (Alternate function) is correct, but if I check on CubeMX, it says the same as on pin description.

Thanks for your help!

​ Hello @thomas23​ ,

The pin description is the correct one:

PA8 = I2C2 SDA

PA10 = I2C2 SMBA

I will report the error to our team for correction.

Thanks for your contribution

This is still an issue even on the latest DS12712 rev4 datasheet available to download. Please be aware!

Just got bitten by this; request User Manual update please.

Hello,

This issue is fixed and the new Datasheet revision is published in the ST website: DS12712 Rev 5.

Thank you.
