U suffix in part number?

[TwelveSquared]

Datasheet does not say what U suffix means in part number.

I.e., what is the difference between STM32H7xxVIT6 and STM32H7xxVIT6U?

[TDK]

It's not super clear, but generally those are parts meant for ST boards, possible preprogrammed, rather than end user applications. I don't think there is any difference in functionality.

That's strange. Digikey and Mouser are showing listings for part numbers with the U suffix (but there's no stock).

In any event, thanks for your reply.

Thanks for pointing that out.
