2 USB0 Evaluation Board Manual Introduction Operation This user manual is for the USB0 Evaluation board. This board can be used to test and evaluate the functionality of the USB0 and is ideal for early system integration and software development. The USB0 EVB provides access to the HSIC upstream and USB downstream ports, as well as the I C communication pins. SMSC also has evaluation software that can be used with the USB0 EVB connected to a Total Phase Aardvark adaptor. This software allows the user to configure the USB0 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.. Contents of the Kit The USB0 EVB includes the basic equipment necessary to evaluate the USB0. The items included in the kit are:. USB0 EVB. V DC Power Supply. Documentation and Software CD The kit does not include any downstream USB devices, I C master hardware, or other components for board customization.. Initial Bring Up Hardware The USB0 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 V power supply. The USB0 EVB will enumerate as a Generic USB Hub, with the VID and PID equal to the default values found in the USB0 Datasheet. The default configuration of the USB0 is to enumerate as a Self Powered Hub. This means that, according to the USB.0 specification, the downstream ports are only allowed to provide 00mA of current to the downsteam device. Refer to the next chapters to see the customization options associated with the evaluation kit. The USB0 EVB is a board that demonstrates the capabilities of the USB0. The board consists of the HSIC upstream and USB downstream ports, a INT_N LED for visual confirmation of the SMSC USB0 EVB Revision.0 (08--)

Downstream USB Digital IO LED USB0 Downstream USB Downstream USB Upstream HSIC. HSIC and USB Ports Figure. Block Diagram of the USB0 EVB The downstream USB ports are mounted on the edges of the USB0 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. Downstream Downstream Downstream J: Strobe J: Data Figure. Upstream and Downstream Ports. Test Points, Switches and LEDs There are multiple test points to confirm that the USB0 EVB is powered properly. TP and TP connect to GND, TP connects to the VBAT pin, and TP connects to the VDD_CORE_REG pin. SMSC USB0 EVB Revision.0 (08--)

4 USB0 Evaluation Board Manual The USB0 EVB also has three switches to manually control the RESET_N and HUB_CONNECT inputs to the part. Figure. shows the location of the test points (Red) and switches (Yellow). The USB0 SCL, SDA, RESET_N, HUB_CONNECT and INT_B pins are also exposed on the J header. These pins are compatible with the Total Phase Aardvark pinout, where pin of the Aardvark connector connects to pin of header J (Refer to Figure. for the proper way to connect the Aardvark). The INT_N pin is also connected to LED to indicate that an interrupt has occurred. The LED remains lit until the interrupt is cleared, as described in the USB0 datasheet. TP TP RESET TP TP HUB_CONNECT LED NOT USED Pin J. Configuration Resistors Figure. Test points, Switches, Header and LED There are eight different resistors used to configure the part when the RESET_N pin transitions from Low (0V) to High(>.V). These resistors are used for the REF_SEL pins. Because these resistors and pads pull up to the.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.. The following tables show the proper configuration resistor population requirements for the desired results, the resistor values should match those found in Section, "USB0 EVB Bill of Materials". Note: The Y Oscillator will need to be replaced with the proper frequency if the REF_SEL pins are altered. Refer to Section, "USB0 EVB Bill of Materials" for recommended oscillator specifications.

Configuration Resistors The U Regulator provides.v to the VBAT pin, and also supplies power to the MHz clock oscillator. If a higher VBAT voltage is desired, remove R and supply the power through TP. The U Regulator provides.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 TP. The USB0 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 VDD_BYP pin allowing the USB0 s internal.v regulator to supply the VDD_CORE_REG voltage. Below is a summary of the different power options and what resistors need to be populated to support these options: Table.

7 USB0 Evaluation Board Manual Software The USB0 EVB comes with a CD that contains evaluation software that can be used with the Total Phase Aardvark USB-IC adaptor (not included with the Evaluation Kit). To install the software, run Setup.exe, found on the CD. This will install the USB0 Evaluation Software, the LabVIEW Runtime 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 USB0 Evaluation.exe program on the computer. Connect the Aardvark to the USB0 EVB with the red wire facing the power port, as in Figure.. Figure. Aardvark Connection 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 IC serial port, as well as some quick configuration and customization options. Figure. USB0 Evaluation Screen SMSC USB0 EVB 7 Revision.0 (08--)

8 USB0 Evaluation Board Manual. 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. 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 USB0 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 USB0 has enumerated, the serial interface registers should not be modified. 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.. I C Communication Figure. Digital Control (Green) and I C (Yellow) sections The application also contains a general I C register read/write section. The Bit and Description display the serial interface register descriptions found in the USB0 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 USB0 datasheet for a detailed description of each register and operation of the device SMSC USB0 EVB 8 Revision.0 (08--)

9 USB0 Evaluation Board Manual. Quick Configuration and Customization The USB0 Evaluation program also contains some quick configuration and customization options that automatically update the registers to match the desired configuration. The USB0 can enumerate as a Self Powered or Bus Powered Hub with, or downstream ports. The VID, PID, DID and enumeration strings can also be customized to allow the USB0 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. Figure.
