I'm trying to find a data sheet for the PCF7941 Ic that is in my car key.

All I can find is a block diagram but I want the pin connections.

Any assistance will be appreciated.
 
hi Len,
I believe this is the processor chip.?

Thanks Eric,
I'll study it later. A brief glace shows that it is similar but there are some differences that I need to check. They may be just terminology.
