Please tell me, why do the two models 5M1270ZF256I5N and 5M1270ZF256C4N appear on the same chip?

Hi,
you are crossposting the question a third time today, but it's still not clear. I'm answering to the old question because the title allows at least a guess of what you are asking.

As far as I understand the question, the answer is quite simple. You have a chip that achieves fastest speed grade 4 in consumer temperature range (0 to 85 °C). It can also be used in industrial temperature range (-40 to 100 °C) but is only achieving slower speed grade 5. This is most likely due to the fact that the FPGA becomes slower at high temperatures.

Hi,

Thank you for contacting Intel Community.

Please note that dual part markings on MAX® V devices are intended to show -4 commercial specifications also meet the -5 industrial specifications.

Refer to our KDB: https://www.intel.com/content/www/us/en/support/programmable/articles/000079006.html
