Cyclone IV memory config

In my design I am using an EP4CE10E22 (Cyclone IV) FPGA and a (Micron?) M25P40 chip for memory configuration. I have two questions: 1) Is the memory chip suitable for CycloneIV? 2) How can I under...

Check the following link for Micron's flash compatibility with Intel FPGAs. You will need to choose the Flash with a high enough capacity so that the design configuration data can fit into it.

The Cyclone IV E device has a maximum uncompressed configuration file as stated below : EP4CE10 2,944,088 Mbits

So, the m25P40 with 4Mbits should be more than enough to store uncompressed configuration data easily.
