SMSC USB3803 EVB USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual 1 Introduction This user manual is for the USB3803 Evaluation board. This board can be used to test and evaluate the functionality of the USB3803 and is ideal for early system integration and software development. The USB3803 EVB provides access to the USB upstream and downstream ports, as well as the I2C communication pins. SMSC has evaluation software that can be used with the USB3803 EVB connected to a Total Phase Aardvark adaptor. This software allows the user to configure the USB3803 in different ways before enumeration and access 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 USB3803 EVB includes the basic equipment necessary to evaluate the USB3803. The items included in the kit are: 1. USB3803 EVB 2. 5V DC Power Supply 3. USB A to Mini-B cable 4. Documentation and Software CD The kit does not include any downstream USB devices, I2C master hardware, or other components for board customization. 2.2 Initial Configuration The USB3803 EVB default configuration configures it to operate as a stand alone hub. To begin, plug the evaluation board into the 5V power supply. After the board is powered up, plug the upstream port into a standard PC host. The USB3803 EVB will enumerate as a Generic USB Hub, with the VID and PID equal to the default values found in the USB3803 Datasheet. The default configuration of the USB3803 is to enumerate as a Bus Powered Hub. This means that, according to the USB 2.0 specification, the downstream ports are only allowed to provide 100mA of current to the downsteam device. Although the evaluation board is designed to provide much more current to the downstream ports, the PC host may generate an error. To avoid this condition, only connect self powered USB 2.0 devices to the downstream ports when using the USB3803 EVB in it’s default state. The USB3803 can also be configured as a Self Powered Hub through the I2C Serial Interface Registers. This will eliminate the 100mA limit error reported by the host PC. Refer to the datasheet for more details. Refer to the next chapters to see the customization options associated with the evaluation kit. SMSC USB3803 EVB 2 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual 3 Hardware The USB3803 EVB is a board that shows the capabilities of the USB3803. The board consists of the USB upstream and downstream ports, a INT_N LED for visual confirmation of the interrupts configured, a header exposing the I2C pins, and additional circuitry that is used for I2C communication. Downstream USB Downstream USB USB3803 Digital IO Downstream USB LED Upstream USB Figure 3.1 Block Diagram of the USB3803 EVB 3.1 USB Ports The USB ports are mounted on the edges of the USB3803 EVB. The downstream ports use the standard USB Type A receptacle. The label for the port is located near the receptacle. The USB upstream port is a standard mini-B receptacle. Downstream1 Downstream2 Downstream3 Upstream Figure 3.2 Upstream and Downstream Ports SMSC USB3803 EVB 3 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual 3.2 Test Points, Switches and LEDs There are multiple test points to confirm that the USB3803 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 USB3803 EVB also has three switches to manually control the RESET_N, BYPASS_N and HUB_CONNECT inputs to the part. Figure 3.3 shows the location of the test points (Red) and switches (Yellow). The USB3803 SCL, SDA, RESET_N, BYPASS_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 USB3803 datasheet J1 BYPASS Pin1 LED1 RESET HUB_CONNECT TP2 TP3 TP6 TP1 Figure 3.3 Test points, Switches, Header and LED 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 and I2C_ASEL pins. Because these resistors and pads connect 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, "USB3803 EVB Bill of Materials". SMSC USB3803 EVB 4 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual Note: The Y1 Oscillator will need to be replaced with the proper frequency if the REF_SEL pins are altered. Refer to Section 6, "USB3803 EVB Bill of Materials" for recommended oscillator specifications.

If a higher VBAT voltage is desired, remove R1 and supply the power through TP2. SMSC USB3803 EVB 5 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual 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 USB3803 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 USB3803’s internal 3.3V 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 3.3 VBAT and VDD_CORE_REG source control VBAT SOURCE VDD_CORE_REG SOURCE R1 R8 R9 INSTALL INSTALL EMPTY Onboard Regulator Onboard Regulator EMPTY INSTALL EMPTY External (TP2) Onboard Regulator EMPTY EMPTY EMPTY External (TP2) External (TP3) INSTALL EMPTY INSTALL Onboard Regulator VDD33_BYP EMPTY EMPTY INSTALL External (TP2) VDD33_BYP The USB3803 EVB also has an option to supply the 5V reference from two different voltage sources. The 5V can come from the upstream USB VBUS or from an external 5V supply. To supply the 5V voltage from the upstream USB port, remove R5 and populate R35 with a 0Ohm resistor. The default is to supply the 5V from an external source.

To install the software, run Setup.exe, found on the CD. This will install the USB3803 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 USB3803 Evaluation.exe program on the computer. Connect the Aardvark to the USB3803 EVB with the red wire facing the power port, as in Figure 4.1. Figure 4.1 Aardvark Connection The software allows the user to control the digital input pins RESET_N, CONNECT, and BYPASS_N. It also can monitor the INT_N pin for interrupts. There is a section to communicate with the I2C serial port, as well as some quick configuration and customization options. Figure 4.2 USB3803 Evaluation Screen SMSC USB3803 EVB 8 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual 4.1 Digital Control The RESET_N, HUB_CONNECT and BYPASS_N 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 USB3803 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. Once the USB3803 has enumerated, the serial interface registers should not be modified. To test the bypass switch functionality, and run the USB3803 in another low power state, set the BYPASS_N pin low. For more information refer to the datasheet for a complete description of each pin’s functionality. Notes: To prevent the Aardvark from driving against another voltage, the Aardvark is operates in Open/Drain mode, therefore it is important that all switches on the board are set to the high position, pulling the pins high. Figure 4.3 Digital Control (Green) and I2C (Yellow) sections 4.2 I2C Communication This application also contains a general I2C register read/write section. The Bit and Description display the serial interface register descriptions found in the USB3803 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 SMSC USB3803 EVB 9 USER MANUAL Revision 1.0 (12-07-12) USB3803 WLCSP-EVB Evaluation Board User Manual will update the current value on the part. Refer to the USB3803 datasheet for a detailed description of each register and operation of the device 4.3 Quick Configuration and Customization The USB3803 Evaluation program also contains some quick configuration and customization options that automatically update the registers to match the desired configuration. The USB3803 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 USB3803 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 enumerate with these options either raise the CONNECT pin, or press the Connect button.
