storage that can be used for configuration as well as software storage. The memory interface can
sustain output synchronous-burst read operations at 40-MHz with zero wait states. The device
defaults to asynchronous page-mode read when power-up is initiated or returned from reset.
This device is also used to store configuration files for the Stratix IV GX FPGA where the MAX II
CPLD (EPM2210) can access flash for FPP configuration of the FPGA using the PFL Megafunction.
Table 2–29
lists the flash pin assignments, signal names, and functions.
