Hi, What are the revisions of the STM32F411CEU6 chip?

The ERRATA doc from STM mentions only revision "A" . Are there other revisions?

I received board with revision "1" .

ST does not update errata too often, especially not for the lesser-exposed models. Often there are revisions related to migration of production to a different fab, with no impact on functionality.

Please note that this is a primarily user-driven forum with only casual ST presence. You may want to ask your question ST directly, through FAE or the web support form.

Thank you Jan. This is very likely that this revision number is from a new fab . But I will contact ST support to verify.

Thank you Tesla, I don't need ST tech support now...

Can you please share the secret? Where do you get this information? What is a way to identify the fab?

The 9R code is TSMC Fab14, Taiwan, the "A" parts look to be VQ which is Crolles, France

Anyways I received a confirmation from ST support that this version "1" is authentic revision of this chip, functionally the same as release "A" but produced in a different fab. Also they will update the errata doc to show this release.
