Revision 1.0 (05-06-13) 2 SMSC USB3503 EVB
USER MANUAL
1 Introduction
This user manual is for the USB3503 Evaluation board. This board can be used to test and evaluate
the functionality of the USB3503 and is ideal for early system integration and software development.
The USB3503 EVB provides access to the HSIC upstream and USB downstream ports, as well as the
I
2
C communication pins.
SMSC also has evaluation software that can be used with the USB3503 EVB connected to a Total
Phase Aardvark adaptor. This software allows the user to configure the USB3503 in different ways
before enumeration as well as monitor and manipulate select status registers during enumeration. The
software can be used to prototype microprocessor software, evaluate the different configurations, and
test how the desired configuration fits into the entire system.
2 Operation
2.1 Contents of the Kit
The USB3503 EVB includes the basic equipment necessary to evaluate the USB3503. The items
included in the kit are:
1. USB3503 EVB
2. 5V DC Power Supply
3. Documentation and Software CD
The kit does not include any downstream USB devices, I
2
C master hardware, or other components
for board customization.
2.2 Initial Bring Up
The USB3503 EVB has a default configuration that allows it to operate as a stand alone hub. To begin,
connect the U.FL connectors to the HSIC host. Then, plug the evaluation board into the 5V power
supply. The USB3503 EVB will enumerate as a Generic USB Hub, with the VID and PID equal to the
default values found in the USB3503 Datasheet.
The default configuration of the USB3503 is to enumerate as a Self Powered Hub. This means that,
according to the USB 2.0 specification, the downstream ports are only allowed to provide 500mA of
current to the downsteam device.
Refer to the next chapters to see the customization options associated with the evaluation kit.
3 Hardware
The USB3503 EVB is a board that demonstrates the capabilities of the USB3503. The board consists
of the HSIC upstream and USB downstream ports, a INT_N LED for visual confirmation of the
USB3503 EVB - Evaluation Board User Manual

USER MANUAL
interrupts configured, a header exposing the I
2
C pins, and additional circuitry that is used for I
2
C
communication.
3.1 HSIC and USB Ports
The downstream USB ports are mounted on the edges of the USB3503 EVB. The downstream ports
use the standard USB Type A receptacle. The label for the port is located near the receptacle. The
HSIC upstream port uses U.FL connectors for Data and Strobe.

USER MANUAL
3.2 Test Points, Switches and LEDs
There are multiple test points to confirm that the USB3503 EVB is powered properly. TP1 and TP6
connect to GND, TP2 connects to the VBAT pin, and TP3 connects to the VDD_CORE_REG pin.
The USB3503 EVB also has three switches to manually control the RESET_N and HUB_CONNECT
inputs to the part. Figure 3.3 shows the location of the test points (Red) and switches (Yellow).
The USB3503 SCL, SDA, RESET_N, HUB_CONNECT and INT_B pins are also exposed on the J1
header. These pins are compatible with the Total Phase Aardvark pinout, where pin 1 of the Aardvark
connector connects to pin 1 of header J1 (Refer to Figure 4.1 for the proper way to connect the
Aardvark). The INT_N pin is also connected to LED1 to indicate that an interrupt has occurred. The
LED remains lit until the interrupt is cleared, as described in the USB3503 datasheet.
3.3 Configuration Resistors
There are eight different resistors used to configure the part when the RESET_N pin transitions from
Low (0V) to High(>1.25V). These resistors are used for the REF_SEL pins. Because these resistors
and pads pull up to the 1.8V regulator, any changes to these resistors will need to be done with the
board unpowered. The resistor pads are laid out in a manner that prevents the pull-up resistors from
being populated at the same time as the pull-down resistors, as shown in Figure 3.4. The following
tables show the proper configuration resistor population requirements for the desired results, the
resistor values should match those found in Section 6, "USB3503 EVB Bill of Materials".

Note: The Y1 Oscillator will need to be replaced with the proper frequency if the REF_SEL pins are
altered. Refer to Section 6, "USB3503 EVB Bill of Materials" for recommended oscillator
specifications.
3.4 Additional Circuitry
The U1 Regulator provides 3.3V to the VBAT pin, and also supplies power to the 26MHz clock
oscillator. If a higher VBAT voltage is desired, remove R1 and supply the power through TP2.
The U2 Regulator provides 1.8V to the VDD_CORE_REG pin as well as providing the pull up voltage
for the digital control pins. To provide external power to the VDD_CORE_REG pin remove R8 and
supply the power through TP3.
The USB3503 can function with a single power supply; to do this remove R8 and place a 0Ohm
resistor on R9. This connects the VDD_CORE_REG pin to the VDD33_BYP pin allowing the
USB3503’s internal 3.3V regulator to supply the VDD_CORE_REG voltage.

4 Software
The USB3503 EVB comes with a CD that contains evaluation software that can be used with the Total
Phase Aardvark USB-I
2
C adaptor (not included with the Evaluation Kit). To install the software, run
Setup.exe, found on the CD. This will install the USB3503 Evaluation Software, the LabVIEW Run-
time engine (to run the executable), and the Total Phase drivers to communicate with the Aardvark.
Once the software has been installed, locate and run the USB3503 Evaluation.exe program on the
computer. Connect the Aardvark to the USB3503 EVB with the red wire facing the power port, as in
Figure 4.1.
Figure 4.1 Aardvark Connection
USB3503 EVB - Evaluation Board User Manual
SMSC USB3503 EVB 9 Revision 1.0 (05-06-13)
USER MANUAL
The software allows the user to control the digital input pins RESET_N and CONNECT. It also can
monitor the INT_N pin for interrupts. There is a section to communicate with the I
2
C serial port, as well
as some quick configuration and customization options.
4.1 Digital Control
The RESET_N and HUB_CONNECT pins can be controlled in real time with the Digital Control array.
Each button in the array corresponds to the pin with the matching name. When the button is orange,
the pin is at logic level High. When the button is black the voltage is a logic level Low. Refer to the
green box in Figure 4.3 for the digital control array location.
Set the RESET_N pin low to reset the part and place it into the lowest power state. If the CONNECT
pin is low when the RESET pin transitions from low to high, the USB3503 will remain in a state that
allows the serial interface registers to be manipulated. To enumerate the hub, either write 00h to
register E7h, or drive the CONNECT pin high by pressing the CONNECT button in the Digital Control.
Once the USB3503 has enumerated, the serial interface registers should not be modified.
Figure 4.2 USB3503 Evaluation Screen
USB3503 EVB - Evaluation Board User Manual
Revision 1.0 (05-06-13) 10 SMSC USB3503 EVB
USER MANUAL
Notes: To prevent the Aardvark from driving against another voltage, the Aardvark is running in an
Open/Drain mode, therefore it is important that all switches on the board pull the pins up to
the Vcc value.
4.2 I
2
C Communication
The application also contains a general I
2
C register read/write section. The Bit and Description
display the serial interface register descriptions found in the USB3503 datasheet. The Register display
can be used to select the proper serial interface register to manipulate. Click on the Value or Bit box
above to change the value of the register. Once the desired value and register are selected, press the
Write button to change the value on the part. Click on the Read button and the Value and Bit boxes
will update the current value on the part. Refer to the USB3503 datasheet for a detailed description of
each register and operation of the device
4.3 Quick Configuration and Customization
The USB3503 Evaluation program also contains some quick configuration and customization options
that automatically update the registers to match the desired configuration. The USB3503 can
enumerate as a Self Powered or Bus Powered Hub with 1, 2 or 3 downstream ports. The VID, PID,
DID and enumeration strings can also be customized to allow the USB3503 to enumerate with
whatever identification is desired.

To change these values; update the configuration section to the desired options, then press the
Configure button. The part will then reset, pull the CONNECT pin low and update the registers as
specified. To go with these options either raise the CONNECT pin, or press the Connect button.
