the MAX® CPLD EPM7064 configuration controller

niosIIuser,

You are correct about the CPLD's purpose on the eval board, but actually the 1c12 eval kits have an EPCS serial flash that can be used to store hardware and software.. the boards power-up with a factory design that boots uClinux (and the linux software/file system resides in parallel flash).

SUN2004,

I believe the only reason for one device being larger than the other was because our config controller design was a tight fit on the 7064, and when Stratix came along (larger configuration size, more address pins to drive), we opted to upgrade to the next larger device to avoid any no-fit issues. I may be incorrect on this but that is what I remember.
