HX2VL has integrated upstream and downstream transceivers; a USB serial interface engine (SIE); USB hub control and repeater logic; and transaction translator (TT) logic. Cypress has also integrated external components such as voltage regulator and pull-up/pull-down resistors, reducing the overall BOM required to implement a USB hub system. The CY7C65642 is a part of the HX2VL portfolio with four downstream ports and an independent TT dedicated for each downstream port. This device option is for low-power but high-performance applications that require up to four downstream ports. The CY7C65642 is available in 48-pin TQFP and 28-pin QFN package options. All device options are supported by Cypress’s world class reference design kits, which include board schematics, BOM, Gerber files, Orcad files, and thorough design documentation. HX2VL Architecture The Block Diagram on page 1 shows the HX2VL TetraHub™ architecture. USB Serial Interface Engine The SIE allows HX2VL to communicate with the USB host. The SIE handles the following USB activities independently of the Hub Control Block. ■ Bit stuffing and unstuffing ■ Checksum generation and checking ■ TOKEN type identification ■ Address checking. HS USB Control Logic ‘Hub Control’ block co-ordinates enumeration, suspend and resume. It generates status and control signals for host access to the hub. It also includes the frame timer that synchronizes the hub to the host. It has status/control registers which function as the interface to the firmware in the MCU. MCU The HX2VL has MCU with 2 K ROM and 64 byte RAM. The MCU operates with a 12 MHz clock to decode USB commands from host and respond to the host. It can also handle GPIO settings to provide higher flexibility to the customers and control the read interface to the EEPROM which has extended configuration options. Transaction Translator The TT translates data from one speed to another. A TT takes high-speed split transactions and translates them to full or low-speed transactions when the hub is operating at high-speed (the upstream port is connected to a high speed host controller) and has full or low- speed devices attached. The operating speed of a device attached on a downstream port determines whether the routing logic connects a port to the TT or to hub repeater. When the upstream host and downstream device are functioning at different speeds, the data is routed through the TT. In all other cases, the data is routed through the repeater. For example, If a full or low-speed device is connected to the high-speed host upstream through the hub, then the data transfer route includes TT. If a high-speed device is connected to the high-speed host upstream through the hub, the transfer route includes the repeater. When the hub is connected to a full-speed host controller upstream, then high-speed peripheral does not operate at its full capability. These devices only work at full speed. Full and low-speed devices connected to this hub operate at their normal speed. Port Control The downstream ‘Port Control’ block handles the connect/disconnect and over current detection as well as the power enable and LED control. It also generates the control signals for the downstream transceivers. Applications Typical applications for the HX2VL device family are: ■ Docking stations ■ Standalone hubs ■ Monitor hubs Hub Repeater ■ Multi-function printers The hub repeater manages the connectivity between upstream and downstream facing ports that are operating at the same speed. It supports full and high-speed connectivity. According to the USB 2.0 specification, the hub repeater provides the following functions: ■ Digital televisions ■ Advanced port replicators ■ Keyboard hubs ■ Gaming consoles ■ Sets up and tears down connectivity on packet boundaries ■ Ensures orderly entry into and out of ‘Suspend’ state, including proper handling of remote wakeups. Document Number: 001-65659 Rev. *F Page 4 of 26 CY7C65642 Functional Overview The Cypress CY7C65642 USB 2.0 Hubs are low-power hub solutions for USB which provide maximum transfer efficiency with no TT multiplexing between downstream ports. The CY7C65642 USB 2.0 Hubs integrate 1.5 k upstream pull-up resistors for full speed operation and all downstream 15 k pull-down resistors and series termination resistors on all upstream and downstream D+ and D– pins. This results in optimization of system costs by providing built-in support for the USB 2.0 specification. Downstream D+ and D– pull-down resistors are incorporated in CY7C65642 for each port. Before the hubs are configured, the ports are driven Single Ended Zero, ((SE0) where both D+ and D– are driven low) and are set to the unpowered state. When the hub is configured, the ports are not driven and the host may power the ports by sending a SetPortPower command for each port. After a port is powered, any connect or disconnect event is detected by the hub. Any change in the port state is reported by the hubs back to the host through the Status Change Endpoint (endpoint 1). On receipt of SetPortReset request for a port with a device connected, the hub does as follows: System Initialization ■ Performs a USB Reset on the corresponding port On power up, CY7C65642 has an option to enumerate from the default settings in the mask ROM or from reading an external EEPROM for configuration information. At the most basic level, this EEPROM has the Vendor ID (VID) and the Product ID (PID), for the customer's application. For more specialized applications, other configuration options can be specified. See EEPROM Configuration Options on page 14 for more details. CY7C65642 verifies the checksum before loading the EEPROM contents as the descriptors. ■ Puts the port in an enabled state ■ Enables babble detection after the port is enabled. Enumeration CY7C65642 enables the pull-up resistor on D+ to indicate its presence to the upstream hub, after which a USB Bus Reset is expected. After a USB Bus Reset, CY7C65642 is in an unaddressed, unconfigured state (configuration value set to’0’). During the enumeration process, the host sets the hub's address and configuration. After the hub is configured, the full hub functionality is available. Multiple Transaction Translator Support After TetraHub is configured in a high speed system, it is in single TT mode. The host may then set the hub into multiple TT mode by sending a SetInterface command. In multiple TT mode, each full speed port is handled independently and thus has a full 12 Mbps bandwidth available. In Single TT mode, all traffic from the host destined for full or low-speed ports are forwarded to all of those ports. This means that the 12 Mbps bandwidth is shared by all full and low-speed ports. Upstream Port The upstream port includes the transmitter and the receiver state machine. The transmitter and receiver operate in high speed and full speed depending on the current hub configuration. The transmitter state machine monitors the upstream facing port while the Hub Repeater has connectivity in the upstream direction. This machine prevents babble and disconnect events on the downstream facing ports of this hub from propagating and causing the hub to be disabled or disconnected by the hub to which it is attached. Downstream Ports The CY7C65642 supports a maximum of four downstream ports, each of which may be marked as usable or removable in the EEPROM configuration, see EEPROM Configuration Options on page 14. Additionally, it can also be configured by pin strapping, see Pin Configuration Options on page 15. Document Number: 001-65659 Rev. *F Babble consists of a non idle condition on the port after EOF2. If babble is detected on an enabled port, that port is disabled. A ClearPortEnable request from the host also disables the specified port. Downstream ports can be individually suspended by the host with the SetPortSuspend request. If the hub is not suspended, a remote wakeup event on that port is reflected to the host through a port change indication in the Hub Status Change Endpoint. If the hub is suspended, a remote wakeup event on this port is forwarded to the host. The host may resume the port by sending a ClearPortSuspend command. Power Switching The CY7C65642 includes interface signals for external port power switches. Both ganged and individual (per-port) configurations are supported by pin strapping, see Pin Configuration Options on page 15. After enumerating, the host may power each port by sending a SetPortPower request for that port. Power switching and overcurrent detection are managed using respective control signals (PWR#[n] and OVR#[n]) which are connected to an external power switch device. Both High/Low enabled power switches are supported and the polarity is configured through GPIO setting, see Pin Configuration Options on page 15. Overcurrent Detection The OVR#[n] pins of the CY7C65642 series are connected to the respective external power switch’s port overcurrent indication (output) signals. After detecting an overcurrent condition, hub reports overcurrent condition to the host and disables the PWR#[n] output to the external power device. OVR#[n] has a setup time of 20 ns. It takes 3 to 4 ms from overcurrent detection to deassertion of PWR#[n] Port Indicators The USB 2.0 port indicators are also supported directly by CY7C65642. According to the specification, each downstream port of the hub optionally supports a status indicator. The presence of indicators for downstream facing ports is specified by bit 7 of the wHubCharacteristics field of the hub class descriptor. The default CY7C65642 descriptor specifies that the port indicators are supported. The CY7C65642 port indicators has two modes of operation: automatic and manual. Page 5 of 26 CY7C65642 On power up the CY7C65642 defaults to automatic mode, where the color of the Port Indicator (green, amber, off) indicates the functional status of the CY7C65642 port. The LEDs are turned off when the device is suspended. 5 V to 3.3 V Regulator 5 V to 3.3 V Regulator NC NC Port Status Indicator LED VCC VREG NC VREG CY7C65642 48 Pin VCC_A Power Regulator CY7C65642 requires 3.3 V source power for normal operation of internal core logic and USB physical layer (PHY). The integrated low-drop power regulator converts 5 V power input from USB cable (Vbus) to 3.3 V source power. The 3.3 V power output is guaranteed by an internal voltage reference circuit when the input voltage is within the 4 V–5.5 V range. The regulator’s maximum current loading is 150 mA, which provides tolerance margin over CY7C65642’s normal power consumption of below 100 mA. The on chip regulator has a quiescent current of 28 µA. VCC CY7C65642 28 Pin VCC_D VCC_A VCC_D External Regulation Scheme Internal Regulation Scheme When the built-in internal regulator is chosen, then the VCC pin has to be connected to a 5 V, in both 48-pin and 28-pin packages. Internally, the built-in regulator generates a 3.3 V and 1.8 V for the chip’s internal usage. Also a 3.3 V output is available at VREG pin, that has to be connected externally to VCC_A and VCC_D. External Regulation Scheme CY7C65642 supports both external regulation and internal regulation schemes. When an external regulation is chosen, then for the 48-pin package, VCC and VREG are to be left open with no connection. The external regulator output 3.3 V has to be connected to VCC_A and VCC_D pins. This connection has to be done externally, on board. For the 28-Pin package, the 3.3 V output from the external regulator has to be connected to VREG, VCC_A and VCC_D. The VCC pin has to be left open with no connection. From the external input 3.3 V, 1.8 V is internally generated for the chip’s internal usage. 3.3 V VREG 5 V VCC CY7C65642 48 Pin VCC_A 3.3 V VREG 5 V VCC CY7C65642 28 Pin VCC_D VCC_A VCC_D Internal Regulation Scheme Document Number: 001-65659 Rev. *F Page 6 of 26 CY7C65642 Pin Configurations Figure 1. 48-pin TQFP (7 × 7 × 1.4 mm) pinout OVR#[1] PWR#[2] OVR#[2] GANG VCC_D SELFPWR 43 42 41 40 39 38 37 44 45 PWR#[1] / I2C_SDA SEL27 GREEN[1] / SPI_SK / 47 46 VCC 48 FIXED_PORT 1 AMBER[1] / SPI_CS VREG VCC_A 1 36 AMBER[2] / SPI_MOSI / PWR_PIN_POL GND 2 35 GREEN[2] / SPI_MISO / FIXED_PORT2 D- 3 34 VCC_D D+ 4 33 AMBER[3] / SET_PORT_NUM2 DD-[1] 5 32 GREEN[3] / FIXED_PORT3 DD+[1] 5 31 PWR#[3] VCC_A 7 30 OVR#[3] GND 8 29 PWR#[4] DD-[2] 9 28 OVR#[4] DD+[2] 10 27 TEST / I2C_SCL RREF 11 26 RESET# VCC_A 12 25 SEL48 CY7C65642 48-pin TQFP 13 14 15 16 17 18 19 20 21 22 23 24 GND XIN XOUT VCC_A DD-[3] DD+[3] VCC_A GND DD-[4] DD+[4] GREEN[4] / FIXED_PORT 4 AMBER[4] / SET_PORT_NUM1 Document Number: 001-65659 Rev. *F Page 7 of 26 CY7C65642 Pin Configurations (continued) Figure 2. 28-pin QFN (5 × 5 × 0.8 mm) pinout VREG VCC PWR#/ I2C_SDA OVR # [1] O VR # [2] GANG SELFPWR 28 27 26 25 24 23 22 1 21 VC C_ D D+ 2 20 O V R # [3] D D - [1] 3 19 O V R # [4] D D + [1] 4 18 TEST/I2C_SCL V C C_ A 5 17 RESET# DD - [2] 6 CY7C65642 16 D D + [4] DD + [2] 7 28-pin QFN 15 DD - D - 9 10 11 12 13 14 RREF V C C_ A XIN XOUT DD D D + [3] V C C_ A - [3] 8 Document Number: 001-65659 Rev. *F - [4] Page 8 of 26 CY7C65642 Pin Definitions 48-pin TQFP Package Pin Name Power and Clock VCC_A VCC_A VCC_A VCC_A VCC_A VCC_D VCC_D VCC Pin No. Type [1] 1 7 12 16 19 34 38 47 P P P P P P P P VCC_A. 3.3 V analog power to the chip.

Page 13 of 26 CY7C65642 EEPROM Configuration Options Systems using CY7C65642 have the option of using the default descriptors to configure the hub. Otherwise, it must have an external EEPROM for the device to have a unique VID, and PID. The CY7C65642 can communicate with an SPI (microwire) EEPROM like 93C46 or I2C EEPROM like 24C02. Example EEPROM connections are shown as follows: Byte 11h–3Fh 40h 41h–6Fh Value Vendor string (ASCII code) Product string length Product string (ASCII code) 70 h 71h–80h Serial number length Serial number string Byte 0: VID (LSB) S P I E E P R O M C o n n e c tio n Least Significant Byte of Vendor ID VDD Byte 1: VID (MSB) A M B E R [1 ] CS VCC G R E E N [1 ] SK NC1 A M B E R [2 ] DI NC2 G R E E N [2 ] DO GND Most Significant Byte of Vendor ID Byte 2: PID (LSB) Least Significant Byte of Product ID Byte 3: PID (MSB)] AT 93C 46 Most Significant Byte of Product ID I2 C E E P R O M C o n n e c tio n A0 Byte 4: ChkSum VDD CY7C65642 will ignore the EEPROM settings if ChkSum is not equal to VID_LSB + VID_MSB + PID_LSB + PID_MSB +1 VCC A1 WP A2 SCL TEST GND SDA P W R # [1 ] Byte 5: Reserved Set to FEh Byte 6: RemovablePorts AT24C02 I2C Note The 28-pin QFN package includes only support for EEPROM like ATMEL/24C02N_SU27 D, MICROCHIP/4LC028 SN0509, SEIKO/S24CS02AVH9. The 48-pin TQFP package includes both I2C and SPI EEPROM connectivity options. In this case, user can use either SPI or I2C connectivity at a time for communicating to EEPROM. The 48-pin package supports ATMEL/AT93C46DN-SH-T, in addition to the above mentioned families. HX2VL can only read from SPI EEPROM. So field programming of EEPROM will be supported only for I2C EEPROM. The default VID and PID are 0x04B4 and 0x6572. CY7C65642 verifies the check sum after power on reset and if validated loads the configuration from the EEPROM. To prevent this configuration from being overwritten, AMBER[1] is disabled when the SPI EEPROM is present.

Bit 1 corresponds to Port 1, Bit 2 to Port 2 and so on. Default value is 0 (removable). These bit values are reported appropriately in the HubDescriptor:DeviceRemovable field. Bits 0,5,6,7 are set to 0. Byte 7: Port Number Port Number indicates the number of downstream ports. The values must be 1 to 4. Default value is 4. Byte 8: Maximum Power This value is reported in the Configuration Descriptor: bMax-Power field and is the current in 2 mA increments that is required from the upstream hubs. The allowed range is 00h (0mA) to FAh(500mA).

Table 1. Features supported in 48-pin and 28-pin packages Pin Configuration Options Supported Features 48-pin 28-pin Power ON Reset Port number configuration Yes No The power on reset can be triggered by external reset or internal circuitry. The internal reset is initiated, when there is an unstable power event for silicon’s internal core power (3.3 V ± 10%). The internal reset is released 2.7 µs ± 1.2% after supply reaches power good voltage (2.5 V to 2.8 V). The external reset pin, continuously senses the voltage level (5 V) on the upstream VBUS as shown in the figure. In the event of USB plug/unplug or drop in voltage, the external reset is triggered. This reset trigger can be configured using the resistors R1 and R2. Cypress recommends that the reset time applied in external reset circuit should be longer than that of the internal reset time. Non-removable port configuration Yes No Reference clock configuration Yes No Power switch enable polarity Yes No LED Indicator Yes No PCB VBUS (External 5V) Silicon Ext. VBUS power-good detection circuit input (Pin"RESET#") R1 EXT Global Reset# INT R2 Power Switch Enable Pin Polarity The pin polarity is set active-high by pin-strapping the PWR_PIN_POL pin to 1 and Active-Low by pin-strapping the PWR_PIN_POL pin to 0. Thus, both kinds of power switches are supported. This feature is not supported in 28-pin QFN package. Port Number Configuration In addition to the EEPROM configuration, as described above, configuring the hub for 2/3/4 ports is also supported using pin-strapping SET_PORT_NUM1 and SET_PORT_NUM2, as shown in following table.Pin strapping option is not supported in the 28-pin QFN package. SET_PORT_NUM2 SET_PORT_NUM1 1 1 1 (Port 1) 1 0 2 (Port 1/2) Gang/Individual Power Switching Mode 0 1 3 (Port 1/2/3) A single pin is used to set individual / gang mode as well as output the suspend flag. This is done to reduce the pin count. The individual or gang mode is decided within 20 µs after power on reset. It has a setup time of 1ns. 50 to 60ms after reset, this pin is changed to output mode. CY7C65642 outputs the suspend flag, once it is globally suspended. Pull-down resistor of greater than 100K is needed for Individual mode and a pull-up resistor greater than 100K is needed for Gang mode. Figure below shows the suspend LED indicator schematics. The polarity of LED must be followed, otherwise the suspend current will be over the spec limitation (2.5 mA). 0 0 4 (All ports) Int. 3.3V power-good detection circuit input (USB PHY reset) VDD (3.3V) VDD (3.3V) PCB Silicon GANG MODE 100K GANG/SUSPEND SUSPEND OUT SUSPEND INDICATOR 100K INDIVIDUAL MODE Document Number: 001-65659 Rev. *F 0 : INDIVIDUAL MODE 1: GANG MODE # Ports Non Removable Ports Configuration In embedded systems, downstream ports that are always connected inside the system, can be set as non-removable (always connected) ports, by pin-strapping the corresponding FIXED_PORT# pins 1~4 to High, before power on reset. At POR, if the pin is pull high, the corresponding port is set to non-removable. This is not supported in the 28-pin QFN package. Reference Clock Configuration This hub can support, optional 27/48-MHz clock source. When on-board 27/48-MHz clock is present, then using this feature, system integrator can further reduce the BOM cost by eliminating the external crystal. This is available through GPIO pin configuration shown below. This is not supported in the 28-pin QFN package.
