Honored ContributorI'd 'simply' choose one that's big enough. I have a standard 16Mbit EPCS (equivalent) connected up to the MAX 10 on my eval board. However, Altera are pushing QSPI devices which offer increased capacity and speed for little cost (2 extra wires) & cost (it'll continue to get cheaper).
Look at this max 10 fpga development kit (https://www.altera.com/products/boards_and_kits/dev-kits/altera/max-10-fpga-development-kit.html). It has a Micron N25Q512A83GSF40F QSPI FLASH connected up. I suggest you consider that a suitable reference design. Cheers, Alex
