Diagram on page 2 shows the HX3 architecture. HX3 consists of two independent hub controllers (SS and USB 2.0), the Cortex-M0 CPU subsystem, an I2C interface, and port controller blocks. SS Hub Controller This block supports the SS hub functionality based on the USB 3.0 specification. The SS hub controller supports the following: ■ SS link power management (U0, U1, U2, U3 states) ■ Full-duplex data transmission USB 2.0 Hub Controller This block supports the LS, FS, and HS hub functionalities. It includes the repeater, frame timer, and four transaction translators. The USB 2.0 hub controller block supports the following: I2C Interface The I2C interface in HX3 supports the following: ■ ■ I2C Slave, Master, and Multi-master configurations 2 2 ❐ Configure HX3 by an external I C master in I C slave mode 2 ❐ Configure HX3 from an I C EEPROM 2 ❐ Multi-master mode to share EEPROM with other I C masters In-System Programming of the I2C EEPROM from HX3’s US port Port Controller The port controller block controls DS port power to comply with the BC v1.2 and USB 3.0 specifications. This block also controls the US port power in the ACA-Dock mode. Control signals for external power switches are implemented within the chip. HX3 controls the external power switches at power-on to reduce in-rush current. The port controller block supports the following: ■ Overcurrent detection ■ USB 2.0 link power management (L0, L1, L2, L3 states) ■ SS and USB 2.0 port indicators for each DS port ■ Suspend, resume, and remote wake-up signaling ■ Ganged and individual power control modes ■ Multi-TT (one TT for each DS port) ■ Automatic port numbering based on active ports CPU Applications The ARM Cortex-M0 CPU subsystem is used for the following functions: ■ Standalone hubs ■ PC and tablet motherboards ■ Docking station ■ Hand-held cradles ■ Monitors ■ Digital TVs ■ Set-top boxes ■ Printers ■ System configuration and initialization ■ Battery charging control ■ Vendor-specific commands for the USB-to-I2C bridge ■ String-descriptor support ■ Suspend status indicator ■ Shared Link support in embedded systems Document Number: 001-73643 Rev. *T Page 4 of 45 CYUSB330x/CYUSB331x CYUSB332x/CYUSB230x HX3 Product Options Table 1.

Application of Shared Link in a Notebook Example: Shared Link Provides Six USB Ports in a Notebook USB 2.0 2 USB 3.0 6 DS4 6 HX3 Internal SS Port USB 3.0 2 D+ D- 4 USB 3.0 SSTX+ SSTX- 6 SS (internal) 6 SSRX+ USB 3.0 6 SSRX- DS3 Standard USB 2.0 Port DS1 4 US PC Chipset USB 3.0 Host SS (internal) USB 3.0 Port Split Into SS Port and Standard USB 2.0 Port USB 2.0 WiFi Module USB 3.0 Camera DS2 Notebook PC Motherboard USB 2.0 HX3 USB 3.0 Port USB 3.0 Card Reader 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. Shared Link enables a maximum of eight DS ports from a four-port USB 3.0 hub. DSx_PWREN is another output signal generated by HX3 and controls VBUS for the removable USB 2.0 device. For example, when an overcurrent condition occurs, DSx_PWREN turns off the port power. For example, if one of the DS ports is connected to an embedded SS device, such as a USB 3.0 camera, HX3 enables the system designer to reuse the USB 2.0 signals of that specific port to connect to a standard USB 2.0 port. Figure 1 shows how Shared Link can be used in an application. Ghost Charge HX3 Ghost Charge is a Cypress-proprietary feature for charging USB devices on the DS port when the US port is not connected to a host. For example, in a docking station with HX3 as shown in Figure 3, when the laptop is undocked, HX3 will emulate a dedicated charging port (DCP) to provide charge to a phone connected on a DS port. USB 3.0 DS Port Figure 3. Ghost Charge Figure 2. DS Port VBUS Control in Shared Link Embedded SuperSpeed Device Power to Smartphone (HX3’s Downstream Port) DSx_PWREN DM USB 2.0 PHY DP SSTXP/M SSRXP/M VBUS DSx_VBUSEN_SL SuperSpeed PHY VBUS Removable USB 2.0 Device The Shared Link mode requires a separate VBUS control for the removable USB 2.0 device and the embedded SS device. Figure 2 shows the VBUS control implementation. USB Cable HX3 Notebook PC Undocked Charge a smartphone without docking the notebook To ensure that the embedded SS device does not fall back to USB 2.0 operation, an external power switch is required. This switch is controlled by HX3, which generates an output signal called DSx_VBUSEN_SL. This signal controls the VBUS for the embedded device. Document Number: 001-73643 Rev. *T Page 6 of 45 CYUSB330x/CYUSB331x CYUSB332x/CYUSB230x When the US port is disconnected from the host, HX3 detects if any of the DS ports are connected to a device requesting charging. It determines the charging method and then switches to the appropriate signaling based on the detected charging specification as shown in Figure 4. The hub either emulates a USB-compliant dedicated charging port by connecting DP and DM (see the BC v1.2 specification) or other supported proprietary charging schemes. Figure 4. Ghost Charge Implementation in HX3 HX3 DS PORT Other Charging Scheme BC v1.2 Scheme Figure 5 shows the ACA-Dock system. If the ACA-Dock feature is enabled, HX3 turns on the external power switch to drive VBUS on the US port. To inform the OTG host that it is connected to an ACA-Dock, the ID pin is tied to ground using a resistor RID_A,3 as shown in Figure 5. The ACA-Dock feature can be disabled using the Configuration Options on page 25. 5V Power Switch VBUS DSx_OVRCURR Figure 5. ACA-Dock Support DSx_PWREN DM In traditional USB topologies, the host provides VBUS to enable and charge the connected devices. For OTG hosts, however, an ACA-Dock provides VBUS and a method to charge the host. HX3 supports the ACA-Dock standard (see BC v1.2 specification) by integrating the functions of the adapter controller. For example, a BC v1.2 compliant phone such as a Sony Xperia (neo V) can be docked to a HX3-based ACA-Dock system. The phone acts as an OTG host and the ACA-Dock charges the phone connected to the US port while also powering the four DS ports. Charging Scheme Detector DP ACA-Dock Support VBUS Power Source 5V Wall Charger Detector Battery Charger Power Switch US_PWREN HX3 USB Battery-Powered Device Ghost Charge is enabled by default and can be disabled through configuration. Refer to Configuration Options on page 25. Vendor-Command Support VBUS To US OTG Enabled Device ID RID_A VBUS Micro A Plug PCB HX3 supports vendor-specific requests and can also enumerate as a vendor-specific device. The vendor-specific request can be used to (a) bridge USB and I2C and (b) configure HX3. This feature can be used for the following applications: ■ Firmware upgrade of an external ASSP connected to HX3 through USB ■ In-System programming (ISP) of an EEPROM connected to HX3 through USB Note 3. 124 k is the recommended RID_A value as per BC v1.2 specification, but some portable devices use custom RID_A values.

Upstream Port (US) This port is compliant with the USB 3.0 specification and includes an integrated 1.5 k pull-up and termination resistors. It also supports ACA-Dock to enable charging an OTG host connected on the US port. Downstream Ports (DS1, 2, 3, 4) DS ports are compliant with the USB 3.0 specification and integrate 15 k pull-down and termination resistors. Ports can be disabled or enabled, and can be set to removable or non-removable options. BC v1.2 charging is enabled by default and can be disabled on each DS port using the configuration options (see Configuration Options). Communication Interfaces (I2C) Reset HX3 operates with two external power supplies, 3.3 V and 1.2 V. There is no power sequencing requirement between these two supplies. However, the RESETN pin should be held LOW until both these supplies become stable. The RESETN pin can be tied to VDD_IO through an external resistor and to ground (GND) through an external capacitor (minimum 5 ms time constant), as shown in Figure 15. This creates a clean reset signal for power-on reset (POR). HX3 does not support internal brown-out detection. If the system requires this feature, an external reset should be provided on the RESETN pin when supplies are below their valid operating ranges. The interface follows the Inter-IC Bus specification, version 3.0, with support for the standard mode (100 kHz) and the fast mode (400 kHz) frequencies. HX3 supports I2C in the slave and master modes. The I2C interface supports the multi-master mode of operation. Both the SCL and SDA signals require external pull-up resistors based on the specification. VDD_IO for HX3 is 3.3 V and it is expected that the I2C pull-up resistors will be connected to the same supply. Figure 15. Reset Connection VDD_IO 10 k RESETN Oscillator 1.5 µF 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-power drive level (
