I have a H735 on a retired board slated for decap so we'll find out once I open it up.

Do you know if it's fabbed in house, TSMC, or Samsung? I've seen ST silicon from all 3 foundries but the only thing I've seen stated publicly is 40nm. When I get it opened up it should be easy to tell, TSMC and Samsung processes have distinctive features on them that I recognize by sight.

No idea - I'm reading the die IDs out of the STM32Cube DB. I haven't looked at the silicon, but I have no reason to doubt what the DB says, especially since it confirms that a lot of allegedly different parts use the same dies.

Now this would be a cool blog post!
