Please see the marking of the EPM3064ATC44-7N, and it's with dual mark. So are they mutually substitutable even the Temperature support range?

You will find that virtually all manufacturers do this dual marking of a Consumer (C) and an Industrial (I) grade device.

You will find that the I grade device will be marked as a slower speed grade (ie, 10ns vs 7ns) over the wider temperature range.

Basically there is only one silicon die design, and it is tested at various temperature and voltage corners to set it speed grade.

Thru their characterization the vendor will have previously determined that a 7ns C device can also be marked as a 10ns I device.

So when you buy the I device you may get a faster C device. Or when you buy the C device you may get a slower I device.
