A. Board Revision History
This appendix catalogs revisions to the Stratix IV E FPGA development board.
Table A–1 lists the versions of all releases of the Stratix IV E FPGA development
board.
Graphics LCD Version Differences
The original graphics LCD part number F-51852GNFQJ-LB-AIN which uses negative
bias voltages connected to nets V1, V2, V3, V4, and V5 has become obsolete. The
replacement module uses positive bias voltages connected to these same nets. This
requires a modification to the power supply on the circuit board.

You should not use the original graphics LCD on a newer, positive bias voltage circuit
board, and conversely, not use the newer graphics LCD on an earlier, negative bias
voltage circuit board.
To determine which graphics LCD model your board is using, refer to the back of the
module itself (J27) for the printed part number. This may require un-snapping the
module from the board.
To determine which type of power supply your board is using, check if your board
has inductors L5 and L6 installed. These inductors are located on the bottom of the
board underneath the graphics LCD.
Single-Die Flash Version Differences
The single-die flash version of the Stratix IV E FPGA development board is created to
replace the obsolete dual-die flash device with a single-die flash device. The two flash
devices are considered equivalent except for some software routines used to access
them because the single-die device has only one CFI table whereas the duel-die
device has two CFI tables.
To determine which flash your board is using, refer to the device part number
installed at U2. The single-die package is smaller than the dual-die version.

E FPGA Development Kit User Guide .
