TK21685 ? Can't find any info on this IC

...did I open it from the wrong side :shot: ?

[dmka]

Nothing on the back side...

So what is this TK21685 ?

Hi
Is that a qr code on that chip. Scan it who knows. Seems it's the only chip that can possibly hold the data on that board. Nothing under the big capacitor?

[dmka]

Nothing under the cap. The qr code is not etched good on the ic, can't read... I'll try to "enhance" it, maybe I can get my camera to read it

[dmka]

Anyone want's to try ?
