hi there
welcome to the forums

have you done any searching for schematics etc yet ?
what happens when you type CASIO CA - 110 keyboard service manual or schematic into google ?
maybe contact casio directly from their www site and see if they can help with info

Dont know for sure yet but i bet its the OKI M6387-13 and it cant be found anymoreso there is not much to do with it if this ic is dead,maybe turn it into a new keyboard by building her another electronic block but how .... ?
