What is the ST Part Number for SO-8 with marking "MZ209"

[jonsiebott]

Can anyone tell me what ST part number in SO-8 Package has the marking "MZ209" ?  Is there a cross reference of all markings available?

That reads like a production site / date code.

Attach a PICTURE, in context, in focus, and large

Here's a pic of the part.  As can be seen there is another number "9321".  I'm grateful for your help.
