Hi,
Do you recognize this puppy or it's manufacturer?

tooki:
And why would you present us with this without explaining what the gadget is? It’s a lot easier to identify a part if you have some idea what it’s doing.

Searching "QFN28 3320" was enough to find this one...

Microchip, previously SMSC, USB3320.

Yes, but the datasheet there clearly shows that’s a QFN32 package, so it can’t be that.
