Had picked up an XC9572 coolrunner devkit some years back. Never got round to it. Wanted to get to using it for a Burgertime crack. Can't find the manual. Do you know if Xilinx has the manual out for the kit?

Is this the one you mean?

It happens to be the first kit I bought as well. It has a Coolrunner XC2C256 in a TQ144 package and an XC9572 in a VQ44 package...

It seems it is the same kit I got some years back: CoolRunner-II. But at that time I had no use for it because I wasn't able to use it with 5V IC's. And because of that I still haven't. Unless I can make a simple interface. Could you, or anyone else, give me some ideas to make good use of it?

One of the nice features of SPI interfaces is that all signals are unidirectional. Thus, the interface is very easy to use with level-shifters, even home-brew circuits.

Towards that end, you could couple your CoolRunner with other logic circuits though high-speed SPI interfaces. It might not be the ideal solution, but it'd at least allow you to get your money's worth.

At the time (last year) I decided to buy it because my curiosity on Xilinx CPLD's was piqued. Honestly, the only things I took away from the board was the JTAG cable and the ISE software. Still well worth it!

Eye: That's the one!. Still hoping to get my #$@#%^ into it one way or another...\

Tony,
Did you see the online manuals? Am I correct in suspecting you need 5v I/O compatibility? What does your design consist of HDL, schematics?

Electric eye: I am going for 5 volts for it. It is the Pinball Mind project as a revision 2, using a 65C02, 32k rom, 32k ram, a 9572 gating CPLD and a sound sample CPLD and possibly an AVR for usb and ethernet communications to the outside world.

Saw the onlines, thanks there. It didnt have the entire huge manual that came with the kit. I think if I keep tearing into the living room, I will find it eventually.

The design is schematics as I work well with logic. The sound unit will be a little trickier but will be based on the Ensoniq DOC5503 to strobe through a sound sample eprom.





Another side CPLD project is cracking the L7 CPU used by a game company. it uses a 6502 internal with gating logic for encryption. I cracked it to a point and it will be a 6502 with a cpld as well.


so it is time to get my (biblical beast of burden) into cpld gear

A reverse engineer you are! Good luck m8!

Came across this app note regarding 5V tolerance techniques using Coolrunner II, while cleaning my desktop...

you betcha. some of my most fun reverse engineering of hardware included a Taito custom coin chip for Arkanoid and the NEC7004 where I have a 3 chip board using an ADC0804....

am getting help for a software revere from good people on here. Thanks kindly, Lee!
