S1R72V27 Evaluation Board Manual EPSON 1
(Rev. 1.0)
1. Overview
This “S1R72V27 Evaluation Board”performs evaluations following connection to a CPU via a CPU I/F
connector. This document describes how to use the board.

2. Jumper Settings
2EPSON S1R72V27 Evaluation Board Manual
(Rev. 1.0)
2. Jumper Settings
Set the jumpers on the board as shown below. Settings marked “*” are default settings.
No. Details Setting (*indicates default)
CN2 +3.3 V supply to CPU board selection *1-2 Supplies +3.3 V (Note 1).
2-3 Does not supply +3.3 V
CN3 +5.0 V supply to CPU board selection *1-2 Supplies +5.0 V.
2-3 Does not supply +5.0 V
JP3 CPU interface voltage setting *1-2 +3.3V (Note2)
1-3 +1.8V
JP8～JP12 *Short Normal setting
S1R72V27 consumption current measuring jumper
(should normally be set to form a short-circuit) Open Setting prohibited
JP15 Short CN5: For both device/host
USB connector (CN5, CN6) function setting
(See section 3 for details.) *Open CN5: Device, CN6: Host
JP16 USB host VBUS output 122 µF location selection *1-2 VBUS switch IC output side
1-3 VBUS switch IC input side
JP17 *1-2 MAX8586-ENRESET pin = High
VBUS switch IC (MAX8586) auto-restart function
selection (See Maxim datasheet for details.) 1-3 MAX8586-ENRESET pin = Low
JP18 *Short With discharge resistor
USB host VBUS output 122 µF capacitor discharge
resistor selection Open Without discharge resistor
Note 1: Due to regulator limitations, avoid using this +3.3 V jumper during normal use.
Note 2: If the CPU I/F level is neither +1.8 V nor +3.3 V, but in between, leave both 1-2 and 1-3 open and apply the
voltage to pin 1.

3. USB Interface Peripheral Circuit
S1R72V27 Evaluation Board Manual EPSON 3
(Rev. 1.0)
3. USB Interface Peripheral Circuit
This board incorporates the following two USB connectors.
•CN5 (USB Mini B): For device functions
•CN6 (USB Standard A): For host functions
DP/DM pins for these connectors are also connected to the DP/DM pins on this IC to facilitate evaluations,
but these circuits are not recommended. This is because mounting components or using wiring patterns like
this may affect impedance matching and reduces signal quality, resulting in communication problems. For
more information, refer to the “S1R72V Series USB 2.0 Hi-Speed PCB Design Guidelines”.
Jumpers are provided on the USB interface peripheral circuit for this reason, and the jumpers should be set
appropriately to suit the evaluation requirements.
Case A: When using CN5 for the device and CN6 for the host
Case B: When using CN5 for both the device and host
Note: CN5 is a Mini B type and can be used only with devices in accordance with USB standards.

(Rev. 1.0)
4. CPU Interface
Connect the CPU to the S1R72V27 via CN4. Refer to “7. Appendix: Circuit Diagrams” for pin assignment
specifics. The CN4 connector and mating connector (provided) are as shown below.
CN4 : NDP100-002-BF / Yamaichi Electronics
Opposite side : NDS100-002-BF / Yamaichi Electronics
5. Power Supply
Connect the board to a power supply with the following characteristics.
CN7
1pin +5V
2pin 0V
3pin N.C.
4pin N.C.
6. Precautions
The following measures are required to input a clock signal to the CLKIN pin.
•Mount CRU1.
•Remove C2, C3, R4, and R18.
•Connect pin XI via a jumper to GND. Leave pin XO open.
The input width to the CLKIN pin must be of the same voltage as CPU I/F Level designated with JP3.
However, for reasons related to the power supply to CRU1, note that this will be 1.8 V for this board.
