Revision 1.0
4 Technical Description
4.1 Host interface
4.1.1 Epson PC Card Extender Support
The evaluation board is designed to connect to the Epson PC Card Extender
(S5UPCMCIAB00C). The extender provides an easy connection to any computer with an
available PC Card slot. The S5U13700B00C directly connects to the extender via
connectors P1 and P2 (see Section 8, “Connecting the S5U13700B00C to the PC Card
Adapter” on page 28).
Note
When using this evaluation board with the Epson PC Card Extender, the maximum cur-
rent draw of 750mA provided by the PC Card slot may be exceeded. If the combination
of module and LCD panel exceeds this limit, an external 5V power supply may be re-
quired. The 5V regulated power supply may be connected to the 5V test point (TP5V1)
and the GND test point (TPGND1) to power the on-board regulator. In this case, the 0
Ohm resistor R2 must be removed from the board.
4.1.2 Host Bus Interface Support
The S1D13700 supports several host bus interfaces. All S1D13700 host interface pins are
available on connectors P1 and P2 allowing the S5U13700B00C to be used for interfacing
to other platforms.
All host interface signals must match HIOVDD of the S1D13700. The default value for
HIOVDD on the board is +3.3V, so it will work with the Epson PC Card Extender
(S5UPCMCIAB00C). HIOVDD can be selected b3.3V and +5V using jumper
JP7.
