Which silicon revision code is actually in production for the STM32H7 family?

[mhafn]

Does anybody know which silicon revision code is actually in production for the STM32H7 family?

[Uwe Bonnes]

From the errate sheet I guess 0x2001

​Looks like there are three revisions of this part: Y, X and V with V being the latest.

Application note AN5312 talks about the differences between them:

I'm wondering how we can order a specific revision.

There is also an older Z version.

It will probably be difficult to get older parts as new silicon is available.

You'll want to qualify functionality of all that you use. Probably not going to be a huge issue as the key features will be additive and working.

Most of the stuff I've seen is Y, the X is about a year old.

Rev.V is out.

According to errata, there's no fixed erratum compared to rev.X.

Errata and RM mentions 'H742.

The H747 is mentioned here. https://www.st.com/content/ccc/resource/sales_and_marketing/presentation/technology_presentation/group0/ca/b8/42/c4/e3/9f/40/2e/CES_2019_Amazon_Alexa_Home_Control/files/CES_2019_Amazon_Alexa_Home_Control.pdf/jcr:content/translations/en.CES_2019_Amazon_Alexa_Home_Control.pdf

Now saying 480 MHz

[MikeDB]

Which of course because of their silly off-line MCU selector program not auto-updating and hence still saying 400MHz, nobody (well me anyway) will know about.

Sigh.

The DS has two sets of electrical characteristics - one for rev.Y and one for rev.V; the latter having an extra VOS0 setting of the internal regulator enabling the 480MHz operation, It's subject to a somewhat limited Tj though, so it's sort of an "overclock", temperature to be watched closely in the application.
