September 2010 Altera Corporation 100G Development Kit, Stratix IV GT Edition Reference Manual

1 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.
