S5U13742P00C100 Evaluation Board User Manual
[attachment=41127]
Introduction
This manual describes the setup and operation of the S5U13742P00C100 Evaluation
Board. The evaluation board is designed as an evaluation platform for the S1D13742
Mobile Graphics Engine.
The S5U13742P00C100 evaluation board can be used with many native platforms via the
host connector which provides the appropriate signals to support a variety of CPUs. The
S5U13742P00C100 evaluation board can also connect to the S5U13U00P00C100 USB
Adapter board so that it can be used with a laptop or desktop computer, via USB 2.0.
This user manual is updated as appropriate. Please check the Epson Research and Development
Website at www.erd.epson.com for the latest revision of this document before
beginning any development.
We appreciate your comments on our documentation.
JP6 - SIOVDD Source
JP6 is used to select the source for the PIOVDD supply voltage.
When the jumper is at position 1-2, the PIOVDD voltage must be provided to the H4
connector, pin 8.
When the jumper is at position 2-3, the PIOVDD voltage is provided by the 3.3V power
supply of the board.
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.
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 regulator to generate adjustable 6~24V, which can be used to power the
LED backlight on some LCD panels.
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 different voltage is required for IOVDD, set JP4 to the 1-2 position
and connect the external power supply to pin 32 of connector H1.
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 oscillator must be 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.
Connecting to the Epson S5U13U00P00C100 USB Adapter Board
The S5U13742P00C100 evaluation board is designed to connect to a S5U13U00P00C100
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 required by the S5U13742P00C100.
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 S5U13742P00C100 which provide a quick visual status of the
USB adapter. LED1 blinks to indicate that the USB adapter board is active. LED2 turns on
to indicate that the USB has been enumerated by the PC.
