The particular model used on this board does not have a backlight and therefore the
LCD drive pin is not connected.
Table 2–23 lists the LCD component references and the manufacturing information.
Flash Memory
The board features a Numonyx PC28F00AM29EWL 1-Gb CFI-compliant NOR-type
flash memory device, which stores configuration files for the FPGA. Both MAX II
CPLD (U72) and FPGA (U44) devices can access the flash. The MAX II accesses are for
FPP configuration of the FPGA using the PFL Megafunction. The FPGA access to the
flash’s user space is provided for embedded NIOS applications.
Table 2–24 provides the pin-out information of the flash memory interface to the
FPGA. The signal direction is with respect to the FPGA device.
