Rev. 3.1
3 Installation and Configuration
The S5U13A04B00C is designed to support as many platforms as possible. The
S5U13A04B00C incorporates a DIP switch and five jumpers which allow both the evalu-
ation board and the S1D13A04 LCD controller to be configured for a specified evaluation
platform.
3.1 Configuration DIP Switches
The S1D13A04 has configuration inputs (CNF[6:0]) which are read on the rising edge of
RESET#. In order to configure the S1D13A04 for multiple Host Bus Interfaces an eight-
position DIP switch (SW1) is required. The following figure shows the location of DIP
switch SW1 on the S5U13A04B00C.

Rev. 3.1
The S1D13A04 has seven configuration inputs (CONF[6:0]) which are read on the rising
edge of RESET#. All S1D13A04 configuration inputs are fully configurable using an eight
position DIP switch as described below.

3.2 Configuration Jumpers
The S5U13A04B00C has five jumper blocks which configure various setting on the board.
The jumper positions for each function are shown below.
JP1 - CLKI Source
JP1 selects the source for the CLKI input pin.
Position 1-2 sets the CLKI source to VCLKOUT from the Cypress clock synthesizer
(default setting).
Position 2-3 sets the CLKI source to the external oscillator at U7.
When no jumper is installed, the CLKI source is set to the BUSCLK signal from Header
H4.

JP3 - LCD Panel Voltage
JP3 selects the voltage level to the LCD panel.
Position 1-2 sets the voltage level to 5.0V (default setting).
Position 2-3 sets the voltage level to 3.3V.
Note
When configured for Sharp HR-TFT or Epson D-TFD panels, JP3 and JP5 must be set
to position 2-3.

Note
1 A0 for these busses is not used internally by the S1D13A04 and should be connected
to VSS.
2 If the target MC68K bus is 32-bit, then these signals should be connected to D[31:16].
3 These pins are not used in their corresponding host interface mode. Systems are
responsible for externally connecting them to Host Interface IO VDD.

1 These pin mappings use signal names commonly used for each panel type, however
signal names may differ between panel manufacturers. The values shown in brackets
represent the color components as mapped to the corresponding FPDATxx signals at
the first valid edge of FPSHIFT. For further FPDATxx to LCD interface mapping, see

The S1D13A04 does not have on-chip PCI bus interface support. The S1D13A04B00C
uses the PCI Bridge FPGA to support the PCI bus.
6.2 Direct Host Bus Interface Support
The S5U13A04B00C is specifically designed to work using the PCI Bridge FPGA in a
standard PCI bus environment. However, the S1D13A04 directly supports many other host
bus interfaces. Connectors H3 and H4 provide the necessary IO pins to interface to these
host buses. For further information on the host bus interfaces supported, see “CPU
Interface” on page 12.
Note
The PCI Bridge FPGA must be disabled using SW1-8 in order for direct host bus inter-
face to operate properly.
6.3 S1D13A04 Embedded Memory
The S1D13A04 has 160K bytes of embedded SRAM. The 160K byte display buffer address
space is directly and contiguously available through the 18-bit address bus.
6.4 Adjustable LCD Panel Negative Power Supply
Most monochrome passive LCD panels require a negative power supply to provide
between -14V and -24V (Iout=45mA). Such a power supply (VLCD) has been provided on
the S5U13A04B00C board. VLCD can be adjusted using potentiometer R39 to provide an
output voltage from -14V to -24V, and is enabled/disabled using the S1D13A04 general
purpose signal, GPIO0 (active high).
Note
When manually adjusting the voltage, set the potentiometer according to the panel’s
specific power requirements before connecting the panel.

6.5 Adjustable LCD Panel Positive Power Supply
Most color passive LCD panels and most single monochrome 640x480 passive LCD panels
require a positive power supply to provide between +23V and +40V (Iout=45mA). Such a
power supply (VDDH) has been provided on the S5U13A04B00C board. VDDH can be
adjusted using R22 to provide an output voltage from +23V to +40V, and is
enabled/disabled using the S1D13A04 general purpose signal, GPIO0 (active high).
Note
When manually adjusting the voltage, set the potentiometer according to the panel’s
specific power requirements before connecting the panel.
6.6 Software Adjustable LCD Backlight Intensity Support Using PWM
The S1D13A04 provides Pulse Width Modulation output on PWMOUT. PWMOUT can be
used to control LCD panels which support PWM control of the backlight inverter. The
PWMOUT signal is provided on the LCD connector, H1.
6.7 LCD Panel Support
The S1D13A04 directly supports:
• Single-panel, single drive passive displays.
• 4/8-bit monochrome interface.
• 4/8/16-bit color interface.
• Active Matrix TFT interface.
• 9/12/18-bit interface.
• ’Direct’ support for 18-bit Sharp HR-TFT LCD or compatible interface.
All the necessary signals are provided on the 40-pin LCD connector H1 and the 16-pin LCD
connector H2. For connection information, refer to Table 5-1: “LCD Signal Connector
(H1)” on page 15 and Table 5-2: “Extended LCD Signal Connector (H2)” on page 17.
6.7.1 Direct LCD Connector
The direct LCD Connector (H1) provides all LCD panel signals required for Active Matrix
TFT and Passive LCD panels. These signals are buffered to either a 3.3V level or a 5.0V
level depending on the setting of JP3. See Table 3-2: “Jumper Summary” on page 9.

6.7.2 Extended LCD Connector
The S1D13A04 directly supports Sharp 18-bit HR-TFT and compatible panels. The
extended LCD connector (H2) provides the extra signals required to support these panels.
The signals on this connector are provided directly from the S1D13A04 without any
buffering and are 3.3V signals.
6.8 USB Support
The S1D13A04 USB controller provides a Revision 1.1 compliant USB client. The
S1D13A04 acts as a USB device and connects to an upstream hub or USB host through
connector J1 on the S5U13A04B00C evaluation board. Clamping diodes have been added
to protect the USB bus from ESD and shorting.
6.8.1 USB IRQ Support
The S1D13A04 supports interrupts through output pin, IRQ. This interrupt can be used to
support interrupts from the USB client of the S1D13A04. The S5U13A04B00C evaluation
board supports this capability by connecting IRQ to the PCI interrupt INTA# of the PCI slot
that the S5U13A04B00C evaluation board is connected to.
