information.
Flash Memory
A 512-Mbit Intel P30 flash memory device is used to store configuration files for the
FPGA as well as any other necessary data for the development board operation. The
target device is a PC48F4400P0VB00 in a BGA package and it supports the common
flash interface (CFI) commands. The flash, SSRAM, and the MAX II CPLD all support
1.8-V I/O, and all three devices share a common address and data bus. The default
addressing mode is a 16-bit word mode. Byte mode requires driving BYTEn low.
Table 2–55 lists the required flash memory signals.
