using commercial FPGA on industrial temp range

[buenos]

hi

is it possible to use a commercial temperature range FPGA on industrial temp range, if we limit the clock frequencies?

for example to 1MHz. Industrial is more expensive, and my application could run on lower freq too. I want to use Actel Fusion FPGA.

It is possible.

But, You oneself must test commerical chip at -40 .. +85C temperature range.

One product line is pass temperature range test.
Chip with stable characteristic in -40 .. +85C temperature range become industrial chip product line.

I.e. industrial chip is -40 .. +85C stable rejection result from common product line.

Usually the component has no problems, but on the long time the plastic body can make some troubles due the different dilatation factor between plastic and metal.
This is more evident on the chip taht dissipate high power.

thats the point, what if i use it at low frequency?
for example a big logic system can run on 40MHz on a given FPGA, then it has to run on 40MHz at 85deg.
what if i use it on 1MHz?

usually FPGA that have an extended temperature range works slower than commercial.
i think that is not a speed problem.
Also if a single device works at low temperature may be that not all future devices works fine.
