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!
Solved! Go to Solution.

​ 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.

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