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 PC28F00AP30BF 1-Gb CFI-compliant NOR-type flash
memory device, which stores configuration files for the FPGA. Both the MAX II CPLD
(U59) and FPGA (U38) devices can access the flash. The MAX II access to the flash’s
user space for FPP configuration of the FPGA using the PFL Megafunction. The FPGA
access to the flash’s user space 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.
