Quartus II 13.0.1 and EPM7256AQC208-7

I have a design idea in which the EPM7256AQC208-7 would be a good fit with regards to number of I/O's, logic capacity, voltage levels and speed/delay. However, as I understand this device is only su...

You might check on the MicroChip/Atmel ATF15nn series parts. They offer 32/64/128 macrocells, are functionally compatible to the obsolete Altera EPM7K/3K series parts, and are still in active production. You can even use QuartusII 13.0sp1 for development.

    My next project is actually a more advanced version of a previous project where I have used the ATF1508. I kind of like them as they work nicely in a 5V environment.

    The problem is I have already used up 99% of the logic cells of the chip. I also need a lot more I/O lines, so the ATF1508 series unfortunately falls short for this one. Splitting the logic to several chips is also not a solution in this case.
