CPLD programmable logic / Re: XC9572XL CPLD Board Questions
Thanks for all the useful info, Guys!

Looks like I am limited to <= 10 MHz clock if I use a generic plastic breadboard:

Areas where the common breadboard does poorly:

High voltage
High frequency (above 10MHz)
Where the additional breadboard capacitance would present problems (oscillators, etc)
Where glitches due to poor wire connections would result in poor operation
Where most of the parts are not through hole 0.1" (2.54mm) centers
For anything but on-the-bench prototyping (ie, don't take it out of the lab and expect it to work)
Sensitive analog electronics, such as sensor usage

CPLD programmable logic / XC9572XL CPLD Board Questions
Can I drive old 5 volt TTL input logic with the 3.3 volt outputs of the XC9572XL?

What is the size of your board? Will it fit onto a generic plastic breadboard?

If I use your board on a generic plastic breadboard what maximum clock rate do you recommend?
