JP1, JP2, JP3, JP5 - Power Supplies for the S1D13742
JP1, JP2, JP3, JP5 can be used to measure the current consumption of each S1D13742
power supply.
When the jumper is at position 1-2, normal operation is selected.
When no jumper is installed, the current consumption for each power supply can be
measured by connecting an ammeter to pin 1 and 2 of the jumper.
The jumper associated with each power supply is as follows:
JP1 for COREVDD
JP2 for PLLVDD
JP3 for IOVDD
JP5 for PIOVDD

4 Technical Description
4.1 Power
4.1.1 Power Requirements
The S5U13742P00C100 evaluation board requires an external regulated power supply
(3.3V / 0.5A). The power is supplied to the evaluation board through pin 34 of the H1
header, or pin 5 of the P2 header.
The green LED ‘3.3V Power’ is turned on when 3.3V power is applied to the board.
4.1.2 Voltage Regulators
The S5U13742P00C100 evaluation board has an on-board linear regulator to provide the
1.5V power required by the S1D13742 Mobile Graphics Engine. It also has a step-up
switching voltage regul ator t o genera te ad justa ble 6~24 V, which can be us ed to power the
LED backlight on some LCD panels.
4.1.3 S1D13742 Power
The S1D13742 Mobile Graphics Engine requires 1.5V and 1.65~3.6V power supplies.
1.5V power for COREVDD and PLLVDD is provided by an on-board linear voltage
regulator.
IOVDD can be in the range of 1.65~3.6V. When JP4 is set to the 2-3 position, IOVDD is
connected to 3.3V. If a di fferent voltage is required f or IOVDD, set JP4 to the 1-2 p osition
and connect the external power supply to pin 32 of connector H1.
Note
If the IOVDD voltage is less than 3.0V, an oscillator working at the selected IOVDD
voltage must be used.
PIOVDD is the power used by the LCD interface and can be in the range of 1.65~3.6V.
When JP6 is set to the 2-3 posit ion, PIOVDD is con nected to 3.3 V. If a diffe rent volt age is
needed for PIOVDD because of the LCD panel requirements, set JP6 to the 1-2 position
and connect the external power supply to pin 8 of connector H4.

4.2 Clocks
The clock for the S1D13742 Mobile Graphics Engine is provided by a 4MHz oscillator.
The S5U13742P00C100 evaluation board has a DIP14 footprint for an optional second
oscillator, Y2. This is provided for cases requiring a different clock frequency for the
S1D13742 Mobile Graphics Engine. To use Y2, an oscillat or must b e populated in the Y2
footprint and the following board modifications must be made.
1. Remove R10 (33 ohm resistor, size 0402) to cut the output of Y1.
2. Populate R13 with a 33 ohm resistor, size 0402, to connect the output of Y2 to the
CLKI input of the S1D13742 Mobile Graphics Engine.
Note
If the board is configured for an IOVDD voltage below 3.0V, an oscillator working at
the selected IOVDD voltage must be used at Y2. The on-board 4MHz oscillator is not
specified to work below a 3.0V supply voltage.
The S1D13742 MGE can output the input cl ock on the CLKOUT pin depending on the state
of the CLKOUTEN input. Both these signals ar e available on the H4 connec tor: CLKOUT
on pin 1 and CLKOUTEN on pin 4. On the board the CLKOUTEN pin is pulled down
which disables the CLKOUT signal. Note that connector H4 is not populated on the
S5U13742P00C100 evaluation board.
4.3 Reset
4.4 Power Save
The S1D13742 Mobile Graphics Engine on the S5U13742P00C100 evaluation board can
be reset using a push-button (SW2), or via an active low reset signal from the host development platform (pin 33 on the H1 connector).
The S1D13742 chip has an input called PWRSVE that will enable (when high) or disable
(when low) the power save mode. This signal is avail able on pin 5 of the H4 connector. On
the board the PWRSVE pin is pulled down which means power save mode is controlled
only by the S1D13742 register setting. Note that connector H4 is not populated on the
S5U13742P00C100 evaluation board.

4.5 Host Interface
4.5.1 Direct Host Bus Interface Support
All S1D13742 host interface pins are available on connector H1 which allows the
S5U13742P00C100 evaluation board to be connected to a variety of development
platforms. For detailed S1D13742 pin mapping, refer to the S1D13742 Hardware Functional Specification, document number X63A-A-001-xx.
The following figure shows the location of host bus connector H1. H1 is a 0.1x0.1”

4.5.2 Connecting to the Epson S5U13U00P00C100 USB Adapter Board
The S5U13742P00C100 evaluatio n bo ard i s designed to connec t to a S 5U13U00P00 C100
USB Adapter Board. The USB adapter board provides a simple connection to any computer
via a USB 2.0 connection. The S5U13742P00C100 directly connects to the USB adapter
board through connectors P1 and P2.
The USB adapter board also supplies the 3.3V power requir ed by the S5U13742P00C1 00.
IOVDD should be selected for 3.3V and JP4 should be set to the 2-3 position.
When the S5U13742P00C100 is connected to the S5U13U00P00C100 USB Adapter
board, there are 2 LEDs on S5U1374 2P00C100 which provide a quick visual status of the
USB adapter. LED1 blinks to i ndicate that the USB adapter board is active. LED2 turns on
to indicate that the USB has been enumerated by the PC.
The following diagram shows the location of connectors P1 and P2. P1 and P2 are 40-pin
headers (20x2).

Note
A windows driver must be installed on the PC when the S5U13742P00C100 is used
with the S5U13U00P00C100 USB Adapter Board. The S1D13xxxUSB driver is available at www.erd.epson.com.

4.6 LCD Panel Interface
The LCD interface signals are available on connectors H2 and H3. For S1D13742 LCD
interface pin mapping, refer to the S1D13742 Hardware Functional Specification,
document number X63A-A-001-xx.
Connector H2 is 0.1x0.1” 2 0-pin header (10x2) and con nector H3 is 0.1x0.1” 40-pi n header
(20x2). For the pinout of connectors H2 and H3, see “Schematic Diagrams” on page 21.
On the evaluation board there is an adjustable 6~24V, 40mA max. power supply. This
voltage is provided only on connector H3 (it is not used elsewhere on the board). It is
intended for use to power t he LED backlig ht on some LCD panels . The voltage is adjust ed
by the R24 pot.
Note
For LCD panels that use a CCFL backlight, an external power supply must be used to
provide power to the inverter for the CCFL backlight. Usually, the inverter current consumption is higher than the maximum 40mA current available from the on-board voltage regulator.
H2
The following diagram shows the location of the LCD panel connectors H2 and H3.
For the pinout of connectors H2 and H3, see “Schematic Diagrams” on page 21.
