Cyclone V - VCCBAT voltage if not using volatile key (3.3V?)

Hello ,

I would like to give you some information about absolute maximum rating before answer your question .

The section is absolute maximum rating means " the device can tolerate not operate at". Stress above the absolute maximum rating can cause the permanent damage to the device. Hence this is stress rating only not the operating rating of the devices. .

Now answer to your question : NO ...I agree with Anand completely.

" Intel cannot guarantee on the performance and reliability of the device if you operate the devices above the maximum recommenced operating rating"

Thank you ,

Regards.,
