    hi, i am trying to program a x24c44p

    pin out is :
    1 - chip enable
    2 - serial clock
    3 - serial data in
    4 - serial data out
    5 - ground
    6 - recall input
    7 - store input
    8 - +5v

    i have a qls2600 which has a icsp out:
    pin out is:

    1 - vpp - programming mode voltage
    2 - vdd - voltage for chip +5
    3 - gnd - ground
    4 - pgd - serial line data ( bi directional )
    5 - pgc - clock line of serial data
    6 - lvp -

    i need to figure out how to interface these too pinouts.

    thanks

    Probably the easiest way to do that is to put a micro controller between them.

    The RAM needs a SPI interface. There may be some way to convince a PICkit 2 to do an I2C interface, but it lacks the 3rd line to do a proper SPI.

    A micro solves this problem.
