Configuration Flash Memory For Cyclone IV E - Military Grade?
I'm designing a military application using a Cyclone IV E device (EP4CE55F23A7N - automotive grade), but can't seem to locate an automotive grade configuration flash memory chip. I need one that goes up to at least 125 degrees C, and I want to us Active Serial AS Mode. Do you have, or can you please recommend, a part for the task? This is a requirement by the Military so any help, part number, etc, that you can provide will be greatly appreciated!
Thanks!

Hi,
The connection to the FPGA looks fine for me. I would recommend you to connect the RESET# of the flash to weak-pull up to avoid it entering reset state.

Thanks JohnT, truly appreciate all your help here.
Got, I will add the weak pull-ups on the flash.
So I have the correct flash pins matched up to the correct pins of the fpga?
