A 512-MB Spansion flash memory device is used to store configuration

files for the FPGA as well as any other necessary data. The target device

does support CFI flash commands. The flash device is used to store

configurations for the Stratix II GX device. Upon power-on one of these

configurations is written into the Stratix II GX device by the MAX II

configuration controller.

f For more information about the flash configuration operation, refer to

“Configuration Schemes and Status LEDs” on page 2–12.
