Migrate to new Spansion SPI NOR Flash for AS configuration

Sorry, I misread your package requirements. I don't think Micron offer that package in that density.

As for compatibility, the Quartus programmer isn't particularly fussy. I've used a number of 3rd party parts, all with success, with the Quartus programmer. Providing it's basic capacity is one the programmer supports (64Mb/EPCS64 is) you should be OK.

However, if you're intending to use the NiosII flash programmer you are very likely to have to add the particular part details to a file the programmer considers when programming device. This thread: nios2-flash-override.txt (http://www.alteraforum.com/forum/showthread.php?t=44094&highlight=%22nios2-flash-override.txt%22) discusses how to do this. The Nios flash programmer supports a number of devices by default and it needs to be told how to support others.

Cheers,

Alex
