SPC8104
SDU8104B
Rev 1.0 ISA Bus Evaluation Board
0B
Test-point Header Strips
All of the pins on the SPC8104F0A are connected to surrounding header strips for easy signal
debugging and testing. Refer to the pin descriptions in X15-SP-001-xx for further details. These
header strips will be mounted on the Solder-side of the board with an associated silk-screen to
identify the pin numbers.
Prototype Area
An area of plate-thru holes with power and ground connections top and bottom is provided on the
board for prototyping additional logic.
PCB Layout Considerations
To provide low signal noise as well as reduced capacitive loading, the LCD Connector is located
near the SPC8104F0A.
Due to the density of the socket, a 6 layer board was necessary so that all signal traces could be
routed to and from the socket pins. Trace thickness must also be reduced to 7mil with 7mil spac-
ing.
Schematic Notes
The evaluation boards may have been modified and therefore the following schematics may not
reflect the actual implementation. Please request updated information before starting any hard-
ware design.
