SPC8104
SDU8104B
Rev 1.0 ISA Bus Evaluation Board

1.3
Technical Description
16-Bit ISA-Bus Support
This board directly supports the 16-bit ISA-Bus and is intended to be used as a ISA-Bus Target
add-in-board. All SPC8104F0A related electrical connections come from the standard in-line
ISA-Bus connectors. Note that all Bus related signals are separated from the ISA-Bus and the
SPC8104F0A by voltage translations circuits. The nature of this design is such that the bus inter-
face I/O pins of the SPC8104F0A are 3.3v only. 8-Bit ISA is supported through JP1-3 and
requires an 8-bit only BIOS.
512K DRAM Support
A one chip 3.3v, 512K solution is supported using a 256K x 16 DRAM. Symmetrical DRAM in an
TSOP package is supported. As the specific DRAM used are 3.3v, there are no voltage transla-
tors in between the 8104 and the memory.
Monochrome LCD Support
The SPC8104F0A supports 4- and 8-bit Dual and Single monochrome STN LCD panels. All the
necessary signals are provided on the 40-pin ribbon cable header (J5) and pass through a 3 V to
5V voltage translation circuitry. The interface signals are alternated with grounds on the cable to
prevent cross talk and noise related problems.
Refer to LCD Panel Configuration and LCD Signal Connector Pinouts above for your specific set-
tings.
MIM Support
The SPC8104F0A also supports 4-bit MIM panels. All the necessary signals are provided on the
40-pin ribbon cable header (J5) and pass through a 3 V to 5V voltage translation circuitry. The
interface signals are alternated with grounds on the cable to prevent cross talk and noise related
problems.
