    Got little problem with a :D
    PIC16C712

    It is already programmed but I can't seem to read the HEX file and also cannot ID check the chip.

    Will the ID check work if code protection bits are set :confused:

    Hello R!f@@,

    Is the PIC an OTP type?
    Most C (CMOS) types are and can be programmed only once.
    The F (flash) types can be programmed several times.

    Bugger!!!! I shud have known tht. :p

    It is a 16C712.
    Does C means one time programmable

    {ed}
    I did check the data, I think it is OTP

    Yes the 16Cxxxx says the chip is like an EPROM without the window. Sorry to say no point of return. And no reprogramming

    Mostly, this one is OTP.
    I think there was a 16C84 that was reprogrammable.
    Microchip part numbers make no sense.

    Hello,

    In the C (cmos) version you have an EPROM as program memory.
    In the F (Flash) version you have a FLASH memory as program memory.
    See the datasheets to compare.(for the F version I have taken the closest).

    Doggonit... I need to read this chip.
    Is there any way to do this?

    It seems unlikely.

    It is perhaps possible but it will cost you a lot of money. I have heard about dodgy firms in China that can do such jobs. But if you are not the owner of the code inside. It is not legal.

    Yeah... Those shops in China and "legal" dont know each other.

    Rifaa, are you just trying to copy the firmware?

    Just trying to read what's inside the PIC to an ASM. I have a PIC file disassembler tht converts the HEX to as ASM
