Problemd with finding datasheet

[J.Tax]

Dear all,

I'm currently bissy with a little projecy, and for that project I use a philils rc 0150 / 01 remote control.

For some minor changes I'm looking for the datasheet of the chip on the pcb, and cant find it any were. The chip on the pcb is a; 'MALAYSIA D6133520' (see picture down below). Does somebody knows where I can find the datasheet or has the datasheet?

I hope you guys/girls can help me.

Greetings,
J.Tax

Thank you very much.
