Hello everyone,

I de-soldered a 24-pin IC from an old Uninterrupted Power Supply's board.
However, I haven't been able to find a datasheet or even information about the manufacturer on the almighty internet so far.

Here's what I've been able to find out from looking at it closely:

What I assume is the model of the IC: UW-524 PBF
And a serial code of sorts: 1465ATB11

On top of the IC, there was an old label (which unfortunately I didn't take a picture of) with the following information on it:
IPS2.0E1
IC 370-2402010


Below you'll find some reference images from the IC and the board it was located on.

If any of you have any ideas on the pinout or the manufacturer, I'd really appreciate it!

Probably a custom microprocessor, or a programmable logic device. The markings on the label are typical of programable parts that I had used for over 5 decades.
