The EVB-USB3503 QFN is designed to demonstrate the unique features of this device using a low-cost PCB implementation with ganged port power control for the three downstream USB 2.0 ports. The EVB-USB3503 QFN is designed to support internal default configuration settings or external configuration through I2C via the SDA and SCL header pins. Figure 2-6 details the top and bottom level silk screen and copper layers. A block diagram of the evaluation board can be seen in Figure 2-7. 2014 Microchip Technology Inc. DS50002252A-page 9 EVB-USB3503 QFN EVALUATION BOARD USER’S GUIDE Chapter 2. Hardware Configuration 2.1 HARDWARE DESCRIPTION 2.1.1 Port Assignment The USB 2.0 downstream ports are numbered 1 through 3. All downstream ports have USB 2.0 connectors with USB 2.0 compliant decoupling and separate shield grounds. Power to all downstream ports is controlled through the MIC2026-1B device U4. When port power is enabled via the PRTPWR pin on the USB3503, port power is delivered to all 3 downstream USB ports. Note: Do not exceed 4 A total current consumption from the + 5 VDC power supply. The EVB-USB3503 QFN must be connected to an HSIC upstream host via the DATA (J5) and STROBE (J4) connectors using the provided U.FL coaxial cables. When removing these cables from the EVB for any reason, the provided HSIC Extraction tool must be used. Figure 2-1shows the recommended usage of the HSIC extraction tool per the Hirose U.FL data sheet on proper use of the plugs. 2014 Microchip Technology Inc. DS50002252A-page 10 Hardware Configuration FIGURE 2-1: RECOMMENDED USAGE OF THE HSIC EXTRACTION TOOL Usage Precautions 1. Plugs (1) Mating/Unmating 1) To disconnect the connectors, insert the end portion of U.FL-LP-N-2 under the connector flanges and pull off vertically, in the direction of the connector mating axis. 2) To mate the connectors, the mating axes of both connectors must be aligned. The “click” confirms a fully-mated connection. Do not attempt to insert on an extreme angle. (2) Pull forces on the cable after the connectors are mated. Do not apply a load to the cable in excess of the values indicated in the diagram below. (3) Precautions Do NOT forcefully twist or deform wires. 2.1.2 USB3503 Configuration 2 Default: I C configuration is bypassed by default on the EVB-USB3503 QFN evaluation board. The hub will use the internal default configuration and automatically transition to the hub communication stage when it is powered on. I2C Option: SW3 must be switched to the 1-2 (see Figure 2-2) position before powering on the hub. SW3 in position 1-2 pulls HUB_CONNECT to ground and will hold the hub in its configuration stage. The hub will not transition to the hub communication stage until CONNECT_N bit of SP_ILOCK register is negated or until SW3 is switched back to position 2-3. Additional hardware capable of two-wire I2C communication is required for I2C operation. For additional information regarding I2C communication protocol on the USB3503, see the USB3503 data sheet. 2014 Microchip Technology Inc. DS50002252A-page 11 EVB-USB3503 QFN Evaluation Board User’s Guide FIGURE 2-2: HUB_CONNECT SWITCH POSITIONS 2.1.3 Clock Source – 26 MHz Oscillator By default, a 26 MHz oscillator (Y1) is populated on the evaluation board as the clock source for the USB3503. The REFSEL[1:0] pins are used to select the frequency of the clock. The board is configured by default to select a 26 MHz clock source by both pulling the REF_SEL0 pin high to +3.3 VDC and pulling the REF_SEL1 pin low to ground. The USB3503 can accept several clock frequencies. If the clock source on the EVB is changed, the resistors connected to the REF_SEL[1:0] pins must be reconfigured to select the appropriate frequency. Table 2-1 shows the resistors that are required in order to select the compatible frequency. The location of the resistors on the EVB can be seen in Figure 2.1.4.

Hardware Configuration FIGURE 2-3: CLOCK FREQUENCY SELECTION REGISTERS 2.1.4 Power Source – Self-Powered The EVB-USB3503 QFN only supports self-powered operation and is powered by one +5 VDC regulated external power supply. The +5 VDC, 4 A power supply plugs into the board via a 2.1 mm connector (J3). The external power supply controls the on board +3.3 VDC voltage regulator and on board +1.8 VDC voltage regulator. The on board +3.3 VDC voltage regulator feeds VBAT on the USB3503. The on board +1.8 VDC voltage regulator feeds VDD_CORE_REG on the USB3503. The USB3503 also has an internal on-chip1.2 V regulator to power the digital logic core. To supply 3.3 VDC externally, remove resistor R1 and connect a 3.3 VDC voltage supply to test point TP2. To supply 1.8 VDC externally, remove resistor R8 and connect a 1.8 VDC voltage supply to test point TP3. The USB3503 can also function with a single power supply; to do this remove R8 and place a 0 Ohm 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. Table 2-2 summarizes the different power options and defines what resistors must be populated for each configuration. Figure 2.1.5 shows the locations of the back-side resistors that are used to configure the different power options.

EVB-USB3503 QFN EVALUATION BOARD USER’S GUIDE Chapter 3. Operation 3.1 CONTENTS OF THE KIT The USB3503 EVB includes the basic equipment necessary for evaluation. The items included in the kit are: 1. 2. 3. 4. USB3503 QFN EVB 5V DC Power Supply U.FL Extraction Tool Documentation The kit does not include an HSIC host device, U.FL cables, any downstream USB devices, I2C master hardware, or other components for board customization. 3.2 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 an 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 data sheet. 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 downstream device. Refer to the next section for customization options associated with the evaluation kit. 3.3 EVALUATION SOFTWARE The USB3503 EVB supports evaluation software available online that can be used to configure the USB3503. This software requires the use of a Total Phase Aardvark USB-I2C adapter (not included with the Evaluation Kit). To install the software, run Setup.exe. This will install the USB3503 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 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 . 2014 Microchip Technology Inc. DS50002252A-page 17 EVB-USB3503 QFN Evaluation Board User’s Guide FIGURE 3-1: 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 I2C serial port, as well as some additional quick configuration and customization options. FIGURE 3-2: USB3503 EVALUATION SCREEN 3.3.1 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 3.3.2 for the Digital Con- DS50002252A-page 18 2014 Microchip Technology Inc. Operation trol 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. Note: FIGURE 3-3: 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. DIGITAL CONTROL (GREEN) AND REGISTERS (YELLOW) 3.3.2 I2C Communication The application also contains a general I2C register read/write section. The Bit and Description display the serial interface register descriptions found in the USB3503 data sheet. 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 data sheet for a detailed description of each register and operation of the device. 3.3.3 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. 2014 Microchip Technology Inc. DS50002252A-page 19 EVB-USB3503 QFN Evaluation Board User’s Guide 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 run with these options, either raise the CONNECT pin, or press the Connect button.
