PEEL/GAL Programming

[Luhan Monat]

Hi,

It seems that the manufacurers of PEEL/GAL chips don't like to provide
information on programming them. Does anybody have access to specs on
programming 18CV8 or such devices?

I think that's because it used to change quite often when they were
current chips- I stopped using 18CV8s after ICT changed the algorithm,
my programmer wouldn't program them any more, there was no update
available from the manufacturer, and I was faced with a 400 pound bill
for a new one. I just bought them in programmed until I changed the
design to use isp CPLDs.

But I'm sure that if you ask ICT nicely they'll tell you what the
current timings are.

Thanks for the info, its about what I suspected. Too bad, I found these
devices very handy in some applications.
