How do I find the datasheet of this device "TIOPA 690 3BZL9"?

It has three rows of text printed on the back, and they are "TIOPA 690

3BZL9". I have this chip, but it was fixed to my board by some other people.

Datasheet or any description that can help me is welcome.

What happened to the text on the front of the chip.. if its been "erased" then you are trying to reverse engineer a design.. that will void the warrantee :-)

And it may void all your "get out of jail free" cards, too. Most people consider that the more serious danger.
