Oh, yes, definitely discontinued. There is stock of either

But, if you REALLY need a 5V-powered CPLD, there are only a
few choices.
The Xilinx 9500 series of CPLDs are not
low-power, by any means.
They have a formula in the data sheet and a power calculator program,
that are both WRONG! They underestimate power by a factor of 3!! I
reported this to them, and they said I was right, but they were not
going to fix the documentation! Sheesh!
I don't believe that Xilinx has
produced the 9500 series for at least a
couple of years. I believe that Atmel still makes some 5V CPLDs
(ATF1500 seies).
I wonder for how long those will remain available. The big
problem is the foundries are shutting down those 5 V processes.
