New ContributorWill EP3C25F324C8NES work at -20C even though it's rated as Commercial Temperature Grade?
We are using an off-the-shelf board that has the EP3C25F324C8NES FPGA on it. We need to operate this board in temperatures down to -20C. The FPGA is rated for temperatures above 0C only. Since the board is part of a custom unique product not manufactured by us it is hard to redesign or replace the parts. In the past a few manufacturers have told me that regardless of the temp. rating of the part, if the part number is the same it comes from the same wafer. Afterwords select dies are tested to lower temperatures and guaranteed down to those temperatures. Same P/N parts regardless of rating could potentially work across a wider temperature range (at least on the lower end).
We are able to do a cold temperature test on the board but we are trying to estimate the viability of that test.
1) Will EP3C25F324C8NES work with ambient temperatures below 0C (assuming a cold soak and then power on)?
2) How far below 0C will it potentially function?
3) What kind of failures are predicted at low temperatures?
4) If failures are observed, are there any ways to mitigate them, i.e. decreasing or increasing clock speed?
Thank you very much for your support.
Sincerely,
Stan
