hello all,
I've made a prototype board with an XC9572XL CPLD (3.3V). I'm currently building a parallel programming cable version II (?)
I wonder wether I can set Vcc to 3.3V or not since parallel port I/O are 5V (but logic levels migth be tolerant).
If not, is the XC9572XL device programmable with a 5V powered cable?
Does anyone have the schematics of a parallel cable version III or IV?
Thanks for your help.
I program XC95144XL with its own 3.3V power supply. I didn't know that I could program it with the power supplied by the cable.

thank you for your experience sharing. Do you know which version this cable is? (II, III, IV ?) Does it make some difference in IMPACT?
I don't know. But it works with XC95144XL. There should not be problem with XC9572XL. I use the latest Xilinx free webpack software (version 6.2?).
