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.
