This appendix is extracted from the XLVDSPRO Demonstration Boards User Guide (UG037).
It describes the LCD interface for the XLVDSPRO demonstration boards, which is identical
to that used in the ML550 Development Board. The documentation is reproduced here for
convenience.
The XlvdsPro_PwrIo board has a full graphical LCD display. This display has been chosen
because of its possible use in embedded systems. A character-type display also can be
connected because the graphical LCD used has the same interface as all character-type
LCD panels.
A hardware character generator must be designed in order to display characters on the
screen.
The FPGA (I/O functioning at 2.5V) is connected to the graphic LCD display through a set
of voltage-level converting devices. These switches translate the 2.5 I/O voltage to a 3.3V
voltage for the LCD display.
To use the display, DIP switch 4 of the switch array DIP1 must be closed. When this switch
is open, the I/O used for the LCD can be used for other applications through the SamArray
connectors.
A graphics-based LCD panel from DisplayTech (64128EFCBC-XLP) is used on the
Virtex-II Pro FPGA board. The control for this LCD panel is based on the KS0713 controller
from Samsung. The KS0713 is a 65-column, 132-segment driver-controller device for
graphic dot matrix LCD display systems. The chip accepts serial or parallel display data.
The 8-bit parallel interface is compatible with most LCD panel manufacturers. The serial
connection mode is write only.
Extra features added to the interface in addition to the normal parallel signals are:
The interface also contains the following built-in options for the display and controller:
Intel or Motorola compatible interface
External reset of the chip
External chip select
On-chip oscillator circuitry
On-chip voltage converter (x2, x3, x4, and x5)
A 64-step electronic contrast control function
