Hi,allI design a digital image precessing board using the Cyclone V 5CEBA4U15I7N. It works well at normal temperature. It don't work under -15℃ when there is no FPGA work current. But it's OK for the power voltage,power sequence and oscillator frequence under -15℃. what's the reason? Thank you for your reply. Best regards. Jimmy
This part is rated to work even at temperatures under -15oC, so it should work.Are you sure that all the other ICs assembled on this board are really specified to work under such temperature ?
