Regulatory Compliance The CY4603, CY4609, and CY4613 kits are intended for use as a development platform for hardware or software in a laboratory environment. The board is designed as an open system, which does not include a shielded enclosure. This may cause interference to other electrical or electronic devices in close proximity. In a domestic environment, these products may cause radio interference. In such cases, you may be required to take adequate preventive measures. In addition, these boards should not be used near any medical equipment or RF devices. Attaching additional wiring to these products or modifying the product operation from the factory default may affect their performance and cause interference with other apparatus in the immediate vicinity. If such interference is detected, suitable mitigating measures should be taken. The CY4603, CY4609, and CY4613 kits as shipped from the factory have been verified to meet with the requirements of CE as a Class A product.

The CY4603, CY4609, and CY4613 kits contain electrostatic discharge (ESD) sensitive devices. Electrostatic charges readily accumulate on the human body and any equipment, and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused boards in the protective shipping package.

End-of-Life/Product Recycling These kits have an end-of life five years from the date of manufacture mentioned on the back of the box. Contact your nearest recycler for discarding the kit.

HX3 Kits User Guide, Doc. #: 001-91203 Rev. *F 5 General Safety Instructions

ESD Protection ESD can damage boards and associated components. Cypress recommends that you perform procedures only at an ESD workstation. If such a workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal surface) on your board when handling parts.

Handling Boards CY4603, CY4609, and CY4613 boards are sensitive to ESD. Hold the board only by its edges. After removing the board from its box, place it on a grounded, static-free surface. Use a conductive foam pad if available. Do not slide board over any surface.

Thank you for your interest in the CY4609, CY4603, and CY4613 HX3 kits. HX3 is a family of USB 3.0 hub controller parts compliant to USB 3.0 specification revision 1.0. These parts support Low-Speed (LS), Full-Speed (FS), Hi-Speed (HS), and SuperSpeed (SS) peripherals. The CY4609 Reference Design Kit (RDK) is a small form-factor, ready-to-use hub reference design. The CY4603 Development Kit (DVK) provides the flexibility to configure and evaluate all HX3 features. The CY4613 DVK implements advanced features, such as Shared Link™ and ACA-Dock. This document is the common user guide for the three HX3 kits, which are based on three different HX3 USB 3.0 hub controller parts. Table 1-1 compares the features of these kits.

Feature Comparison of HX3 Kits Feature CY4609 CY4603 CY4613 Status LEDs Power Yes Yes Yes Hub Suspend Status Yes Yes Yes Downstream Port Status Indicators No Yes Yes Shared Link™ No No Yes ACA-Dockd No No Yes a. Shared Link is a Cypress-proprietary feature that enables a USB 3.0 port to be split into an embedded SS port and a standard USB 2.0 port. b. Battery Charging is supported on standard USB 3.0 and Shared Link USB 2.0 ports only. c. Ghost Charging is a unique feature with which a downstream port emulates a dedicated charging port (DCP) to support charging even when the upstream port is not connected to a USB host. d. In traditional USB topologies, the host DS port provides VBUS to enable and charge the connected devices. With OTG devices, however, the ACA-Dock provides VBUS and a method to charge the host. HX3 supports the ACA-Dock standard (see section 6 of the BC v1.2 specification for more details) by integrating the functions of the adaptor controller.

The GPIOs used to implement the port status indicator LEDs (except D10, D11, and D12) are also used for implementing the pin strap feature. For example, the DS1_GRN port status indicator LED on the CY4603 board is shared with the PORT_DIS[0] pin strap feature, as shown in Figure 3-18. The PORT_DIS[0] pin strap feature is implemented using a three-pin jumper. When the jumper is placed between pin 1 and 2, the shared GPIO used for the PORT_DIS[0] feature is pulled HIGH. When the jumper is placed between pins 2 and 3, it is pulled LOW. To support the port status indicator LED functionality in both the pull-up and pull-down settings, one LED is used for each setting.

Refer to Table 1-4 on page 12 for more details about the abbreviations listed in this table. b. Green status LEDs (DS1_GRN and DS2_GRN) on the Shared Link ports DS1 and DS2 are disabled as the two GPIOs used for these LEDs are reassigned to enable power to DS1 SS and DS2 SS ports. Therefore, these LEDs will not turn on when the USB 2.0 devices are connected to the DS1 or DS2 USB 2.0 downstream port. Note that pin strap features are not supported on the current CY4613 board configuration. This is due to settings related to Shared Link, which are stored in the CY4613 board's EEPROM by default for the CYUSB3328 part. The settings in the EEPROM enable configuring the CYUSBS3328 to support Shared Link on DS1 and DS2 ports to match with the CY4613 board design. When the settings are stored in the EEPROM, they take precedence over the pin strap features. On the CY4613 board, a USB 3.0 data transfer and USB 2.0 data transfer can be simultaneously done on Shared Link ports as shown in Figure 3-19 on page 31.

Connect a USB 2.0-certified flash drive to a standard USB 2.0 downstream port (DS1). Note: The board must be in the powered-off state while connecting a device on any Shared Link SS downstream port. This is because the Shared Link SS ports are configured as embedded ports (nonremovable device); the devices are expected to be permanently connected to the DS ports even before being powered on. Copy a 2-GB file from the PC to both the flash drives. SS and USB 2.0 data transfers happen simultaneously on the Shared Link downstream ports.

3.4.5 Ghost Charging Disconnect the USB cable from the upstream port to detach the board from the PC, as shown in Figure 3-21. The board continues to charge the device connected to the downstream port using the Ghost Charging feature. Notes: ■ While the board is switching to the Ghost Charging mode, it stops charging the device connected to the downstream port momentarily and resumes charging within 1 to 2 seconds. ■ The current drawn by the device in Ghost Charging mode may vary compared to the current drawn in normal Battery Charging mode. Figure 3-21. Ghost Charging

Disconnect the USB cable f from the upstream port

According to the USB-IF Battery Charging specification v1.2, charging downstream ports (CDPs) are expected to provide 1.5-A current (typical) per port. The power adapter shipped with CY4609 and CY4603 supports up to 4 A of load current. After calculating the power consumed by HX3 and other parts of the board, 3.6 A is available to support charging on the downstream ports. When the board is used with the 5-V/4-A power adapter, ensure that no more than two downstream ports are used as CDP. If the current consumed by the downstream ports exceeds 3.6 A, the CY4609 board detects an overcurrent condition and interrupts HX3, which disables power to all the downstream ports until the overcurrent condition is removed and the board is reset.

3.4.6 Configuring HX3 Using Pin Straps on CY4603 You can configure HX3 using pin strap GPIOs. The “Configuration Options” section of the HX3 datasheet gives more details about the use of pin strap GPIOs. A pin strap GPIO can be strapped to logic '1' by shorting pins 1 and 2 using a jumper. It can be strapped to logic '0' by shorting pins 2 and 3. Figure 3-22 illustrates the pin strap jumpers on the CY4603 board. Figure 3-22. Pin Strap Jumpers on CY4603 Board

3.4.7 ACA-Dock Feature on CY4613 The ACA-Dock feature helps to demonstrate the USB host functionality while charging. Normally when a host-capable handheld device such as a phone is connected to a device on the DS port, the VBUS is provided by the USB host. When the battery is drained and the host-capable phone needs to be charged, the host functionality cannot be exercised until the phone is charged. To enable the USB host functionality while charging, USB-IF has implemented the ACA-Dock feature (BC v1.2 specification). This allows the host-capable battery devices to be charged and at the same time exhibit the host functionality. Refer to ACA- Dock Implementation on page 75 for more details. This section describes the procedure to set up and use the ACA-Dock feature on the CY4613 board. Figure 3-23. Configuring CY4613 Board for ACA-Dock

ACA-Dock configuration jumpers J26, J27, and J28)

Note that the ACA-Dock feature is disabled by default on the CY4613 board. Following is the procedure to enable and use the ACA-Dock feature. 1. Power off the HX3 board by disconnecting the AC-DC power adapter from the DC jack and remove the USB 3.0 standard-A to micro-B cable. Remove the devices on the downstream ports. 2. Install a jumper between pins 2 and 3 of J28. Install jumpers on pin 1 and 2 of J26 (PWR_HOST) and J27(RID). Installing a jumper on J26 enables 5-V VBUS on the US connector. Installing a jumper on J27 enables the ID termination resistor required for the ACA-Dock feature according to the BC v1.2 specification. Note: To use ACA-Dock feature with Samsung Galaxy Note 3, S3 and S4 devices, install jumper on pins 2 and 3 of J27. 3. Get a BC v1.2-compliant phone with the OTG host capability such as Sony Xperia (S / P / neo V). Connect one end of the micro-B to micro-B cable to the USB 2.0 portion of the HX3 board's upstream port as shown in Figure 3-24. Connect the other end of the cable to the phone. CAUTION: Make sure the phone is compliant with the BC v1.2 specification before using with the HX3 board. Using the board with a non-BC v 1.2-compliant host can damage or affect the phone functionality.

3.4.8 I2C Slave Mode Operation

The CY4603 and CY4613 DVKs support I2C slave mode operation which enables configuration of HX3 from an external I2C master. Following is the procedure to use the HX3 DVKs in I2C slave mode: 1. Generate the 'HX3 I2C Slave Mode file' using the required configuration parameters together with the firmware by following the instructions specified in Generating 'HX3 I2C Slave Mode file' for CY4603 and CY4613 DVKs on page 55. 2. Configure the HX3 DVK for I2C slave mode operation by setting the configuration mode selection jumpers as mentioned in Table 3-9. Table 3-9. Configuration Mode selection DVK Configuration Mode Jumper Setting J17: Short pins 2 and 3 CY4603 J18: Short pins 1 and 2 J5: Short pins 2 and 3 CY4613 J6: Short pins 1 and 2

3. Connect the HX3 DVK to I2C master device by connecting wires to GND, SCL and SDA pins of I2C header.

4. Power on HX3 DVK and the I2C master device. Connect HX3 to a PC / laptop. Send the 'HX3 I2C Slave Mode file' content from the I2C master device. HX3 kit enumerates on the PC / laptop using the firmware and configuration settings sent from the I2C master. Note: The HX3 kit will not enumerate until it receives the firmware and configuration settings from the I2C master device. 5. Once the I2C slave mode usage is completed, detach the I2C master device and restore the kits to custom firmware state by setting the configuration mode selection jumpers as mentioned in Table 3-9. Note: The firmware and configuration settings sent from the I2C master are stored in HX3’s RAM memory. Hence the I2C master needs to send the firmware and configuration settings every time HX3 is reset or powered on.

The CY4609 RDK is based on the CYUSB3304-68LTXC hub controller. It is a small form-factor hardware supporting four USB 3.0 downstream ports that conform to USB 3.0 and BC v1.2 specifications. The ports also support Ghost Charging and emulate Apple charging. The upstream port is implemented using a USB 3.0 micro-B connector. The RDK is shipped with a 5-V AC-DC adapter with a current rating of 4 A. However, the hardware is designed to support operation with an AC-DC adapter with up to a 6-A current rating. The CYUSB3304-68LTXC hub controller is clocked using a 26-MHz crystal on the board. The HX3 hub controller supports an I2C communication interface; it can support both slave and master modes. On the RDK, an EEPROM is connected to the hub controller on this interface to store the configuration data and firmware.

5.1.3 Functional Description

5.1.3.1 Power Supply This section describes the hardware circuit implemented on the CY4609 RDK hardware to supply the required 5-V, 3.3-V, and 1.2-V power supplies, as shown in Figure 5-2. It also describes the circuit implemented to monitor and control overcurrent conditions on downstream ports. Figure 5-2. Power Regulators for 3.3-V and 1.2-V Power Domains

HX3 (CYUSB3304-68LTXC) requires four power domains, as detailed in Table 5-1.

Table 5-1. HX3 Power Domains Parameter Description Min Typical Max Unit AVDD12 1.2-V Analog supply 1.14 1.2 1.26 V DVDD12 1.2-V Core supply 1.14 1.2 1.26 V AVDD33 3.3-V Analog supply 3 3.3 3.6 V VDDIO 3.3-V I/O supply 3 3.3 3.6 V

These power domains can be served using two power supplies (3.3 V and 1.2 V). The CY4609 RDK is designed to support these power supplies using two independent DC-DC regulators. The 5-V supply from the AC-DC adapter is fed to a 5-V-to-3.3-V DC-DC regulator (AOZ1021AI) to create a 3.3-V supply. The output from this regulator is fed to a 3.3-V-to-1.2-V DC-DC regulator (SC189CSKTRT) to create a 1.2-V supply. The DC jack used on the RDK supports the AC-DC adapter with a center-positive configuration. If an AC-DC adapter with a center-negative configuration is connected to the RDK, the blocking diode of the MOSFET (Q1) provides reverse-polarity protection and avoids damage to the hardware. The power LED (PWR) is connected on the input 5-V line and glows continuously when a 5-V supply is provided to the hardware.

HX3 Kits User Guide, Doc. #: 001-91203 Rev. *F 61 Hardware

The power (5-V VBUS) to downstream ports is controlled using a power switch (U5, TPS2556DRBT) as shown in Figure 5-3. This switch gets input from the 5-V AC-DC adapter connected to the hardware. The output of the power switch can be enabled and disabled by the HX3 using the Power Enable (PWR_EN_DS) GPIO. After the output of the power switch is enabled, it monitors the current consumed by all the devices attached to the downstream ports in ganged mode. When the total current consumed exceeds 4.85 A, the power switch interrupts the HX3. The HX3 in turn immediately disables the output of the power switch by pulling the Power Enable (PWR_EN_DS) GPIO HIGH. This disables the power (5-V VBUS) to all four downstream ports; the hub controller notifies the PC that all the downstream ports are shut down. Figure 5-3.

HX3 requires an external crystal with a frequency of 26 MHz and an accuracy of ±150 ppm in parallel resonant, fundamental mode. The crystal drive circuit is capable of a low-drive level (<200 µW). The crystal circuit implemented using the NX3225SA-26.000000MHZ-G4 part meets these requirements. HX3 undergoes a hardware reset when the RESETN pin is pulled LOW. The RESETN pin is tied to the power supply (V3p3) through an external resistor and to ground (GND) through an external capacitor as shown in Figure 5-5. This RC circuit implements a 15-ms reset timing at power on, which guarantees the stable operation for HX3. There is also an external reset button to reset the HX3 hub controller manually whenever needed. Figure 5-5. Reset Design

HX3 supports the I2C communication interface, which can be configured in the master or slave mode. On the CY4609 RDK, an onboard I2C-based EEPROM (24LC128-I/SM) with an address of 10100010b is connected, with HX3 acting as the I2C master. The storage capacity of this EEPROM is 16 KB. Test points are provided on the I2C data (I2C_SDA) and clock (I2C_SCL) lines to connect any external device over the I2C interface. Note that the current CY4609 hardware design provides the flexibility to enable or disable Write Pro- tect (WP) for the I2C EEPROM during assembly time. WP can be disabled by assembling a 0- resistor between WP and GND; it can be enabled by assembling a 0- resistor between WP and V3p3. WP is disabled by default on the CY4609 hardware to enable configuration data to be stored on the EEPROM using the HX3 Blaster Plus tool.

5.1.3.6 Test Points Table 5-4 lists the test points available on the CY4609 hardware and the associated signal names.

The CY4603 DVK supports four downstream ports, which are terminated as USB 3.0 type-A connectors. All these downstream ports conform to the USB 3.0 and BC v1.2 specifications. They also support Ghost Charging and emulate Apple charging. Each downstream port is controlled using a power switch, which allows monitoring an overcurrent situation on each downstream port and the shutdown of the ports with an overcurrent condition selectively. The CYUSB3314-88LTXC hub controller is clocked using a 26-MHz crystal. More details about the crystal specification are available in the HX3 datasheet. The DVK is powered using a 5-V AC-DC adapter. The DVK is shipped with a 5-V AC-DC adapter with a current rating of 4 A. However, the power supply tracks on the DVK hardware are designed to support up to 8 A of input current. The

HX3 Kits User Guide, Doc. #: 001-91203 Rev. *F 67 Hardware

DVK contains two onboard DC-DC regulators to provide 3.3-V and 1.2-V power supplies to the HX3 hub controller. A 5-V input from the AC-DC adapter is directly passed to the downstream ports via power switches. The HX3 hub controller supports the I2C communication interface; it can support both slave and master modes. On the DVK, an I2C EEPROM is interfaced to the hub controller to store the configuration data and firmware, with the hub controller acting as the I2C master.

5.2.3 Functional Description

5.2.3.1 Power Supply CY4603 uses the same power supply circuit as CY4609 to generate 3.3-V and 1.2-V power supplies. The design of CY4603 differs from that of CY4609 with respect to the implementation of power control. CY4603 implementation supports monitoring an overcurrent condition at each downstream port using a power switch. To reduce the number of power switches, CY4603 uses two dual-channel power switches (TPS2560DRC) as shown in Figure 5-12. Each switch can control two downstream ports. These power switches are configured to interrupt the HX3 hub controller when the current drawn by the connected downstream device exceeds 2.1 A. In response, HX3 immediately shuts down the power supply (VBUS) to that downstream port by disabling power enable on the corresponding channel (for example, DS1_PWREN) of the power switch.

5.2.3.2 LEDs and Jumpers CY4603 uses the same circuit as CY4609 for the boot mode selection jumper and for the Power (PWR) and Suspend (SUSP) LEDs. However, CY4603 implements three LEDs per downstream port to indicate SuperSpeed (blue), USB 2.0 (green), and exception (amber) status. Figure 5-13 illustrates the circuit implementing this functionality. This diagram also captures the pin strap configuration circuit that is implemented by sharing GPIOs used for status LEDs.

5.3.3 Functional Description

5.3.3.1 Power Supply This section describes the hardware circuit implemented on the CY4613 DVK hardware to provide the required 5-V, 3.3-V, and 1.2-V supplies. A 12-V DC-DC regulator is used to generate the 5-V supply. The output of the 12-V to 5-V regulator is fed to a power switch, which limits the maximum current to 5 A to prevent excess heating of the 12-V to 5-V DC-DC regulator. CY4613 uses the same power circuit as the CY4609 to generate the 3.3-V and 1.2-V supplies. A Ferrite Bead (L12) is used at the input of the 3.3-V regulator to remove excess ripple from the 12-V to 5-V DC-DC regulator. Figure 5-15.

5.3.3.6 ACA- Dock Implementation In traditional USB topologies, the host DS port provides VBUS to enable and charge the connected devices. With OTG devices, however, the ACA-Dock provides VBUS and a method to charge the host. HX3 supports the ACA-Dock standard by integrating the functions of the adaptor controller. Figure 5-17 shows the ACA-Dock system. If ACA-Dock is enabled, HX3 turns on the external power switch to drive VBUS on the US port. To inform the device connected on the US port that it should act as a host and draw current, the ID pin is connected to ground using RID_A as shown in Figure 5-17. Figure 5-17.
