1. Overview
S1R72U16 Evaluation Board Manual (Rev1.10) EPSON 1
1. Overview
This board is an evaluation board for the S1R72U16. This manual describes how to use the board.

2. Connector Connections
2 EPSON S1R72U16 Evaluation Board Manual (Rev1.10)
2. Connector Connections
The connectors provided on this board are shown below.
Connector No. Usage
CN1 Connects to main CPU system
CN2 Connects to PORT00 to PORT02 (not included)
CN3 Monitors PORT10 to PORT17 (not included)
CN4 For S1R72U16 maintenance (not included)
CN5 USB connecto
r
CN6 Power supply connecto
r
CN7 RS232 connecto
r
CN1
Use Connector CN1 to connect the board to the main CPU system.
Pin assignment conforms to the IDE bus when connecting in IDE mode, enabling use of a
commercially-available IDE bus 40-pin cable. The cable should support at least ATA100.
The same cable may be used when connecting in CPU mode. Check the pin assignment when connecting.
In either case, avoid using long cables in which the individual signal wires are not guarded by GND, since
degraded signal quality or incorrect operations may result.
CN6
The power supply to the board should be connected to connector CN6 as shown below. Note that the power
should be turned on only after connecting to the main CPU and making the settings described further below.
1pin +5V
2pin 0V
3pin N.C.
4pin N.C.
CN7
Use Connector CN7 for RS-232 connections to a PC. Commercially-available RS-232 cross cables may be
used.

3. Switches

Note:
The pins of CN2 (not mounted) are connected to PORT00 to PORT02. When using these pins, set the
corresponding position on SW1 to Off, and set the input signal level to CN2 to the same as for IOVDD.
SW2 is for resetting the S1R7U16 chip.

4. LEDs
4 EPSON S1R72U16 Evaluation Board Manual (Rev1.10)
4. LEDs
The LEDs provided on the board allow the output status of the S1R72U16’s PORT10 to PORT17 to be
checked. The LEDs illuminate when the PORT output is High (1). The LEDs and PORTs correspond as
shown below.

Note:
The pins of CN3 (not mounted) are connected directly to each PORT of the S1R72U16 as shown in the table
above. These can be probed to monitor the signals for PORT10 to PORT 17. The output level will be the
level supplied to the IOVDD pin.

5. Jumper Pins
S1R72U16 Evaluation Board Manual (Rev1.10) EPSON 5
5. Jumper Pins
The jumpers on the board are set as shown below. Factory default settings are shown shaded.
JP1 must be used as Short (CSEL = Low) when using the LSI in two-device mode
JP3 should be used as 1-2 Short when using the interface settings in IDE mode.
JP4 to JP10 are soldered jumpers and normally do not need to be changed.
No. Details
