    i also wonder if such PIC PROGRAMMER USB SMD can reprogram it

    This is a ST 93S56 EEPROM. A PIC programmer is imho not suitable for programming this chip. It is, however, easy to program such a chip via its serial interface from most any microcontroller (arduino, raspberry, ...). For most of them you will find ready to use libraries (e.g. for arduino here) to program such a chip.
    You will have to remove the chip from the board - otherwise you risk not being able to program the chip due to interference from other circuit parts on the pcb.

    Where do you get the contents from that you want to program into the chip?

    it's an old car odometer board
    is there any tutorial on how to such thing , and can i do it through old pc with serial port? but how to connect it and what application can i use to reprogram it

    Maybe this article can help you. Or Google "serial eeprom programmer".
    How do you know which contents to program? You are not trying to manipulate the odometer, are you?

    i'm getting it from an old odometer and will install it to another board that's why i need to reprogram it

    what about MiniPRO TL866CS USB Universal Flash EEPROM Programmer

    or what do you think about this way to pc serial port

    although i'm not sure how to manage the +5 voltage input

    The file shows data for M93S46-W M93S56-W and M93S66-W. The difference is in the memory size.

    reprogram it with what? new code? new data? whic code, which data? Where would you get these from?

    not sure yet, i'm taking it step by step, it's for my learning purposes so first i learn how to be connected and what application i use to program it , then i switch to the code part

    the memory of M93S56-W is 2k bit
