low-power USB 2.0 hub controllers. HX2LP is an ultra low power single chip USB 2.0 hub controller with integrated upstream and downstream transceivers, a USB serial interface engine (SIE), USB hub control and repeater logic, and TT logic. Cypress has also integrated many of the external passive components, such as pull-up and pull-down resistors, reducing the overall bill of materials required to implement a hub design. The HX2LP portfolio consists of: the route only includes the repeater and no TT, because the device and the hub are operating at the same speed. When the hub is operating at full-speed (the upstream port is connected to a full-speed host controller), a 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. Applications Typical applications for the HX2LP device family are: ■ Standalone hubs This device option is for ultra low-power applications that require four downstream ports. All four ports share a single transaction translator. The CY7C65630 is available in 56 QFN and is also pin-for-pin compatible with the CY7C65640. ■ Motherboard hubs ■ Monitor hubs ■ Advanced port replicators ■ ■ Docking stations ■ Split-PC designs ■ External personal storage drives ■ Keyboard hubs ■ CY7C65630: 4-port/single transaction translator CY7C65620: 2-port/single transaction translator This device option is for a 2-port bus powered application. Both ports share a single transaction translator. The CY7C65620 is available in a 56 QFN. All device options are supported by Cypress’s world class reference design kits, which include board schematics, bill of materials, Gerber files, Orcad files, and thorough design documentation. USB Serial Interface Engine The serial interface engine (SIE) allows the CY7C65620/CY7C65630 to communicate with the USB host. The SIE handles the following USB activities independently of the Hub Control Block. Functional Overview The Cypress CY7C65620/CY7C65630 USB 2.0 Hubs are high-performance, low system cost solutions for USB. The CY7C65620/CY7C65630 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. ■ Bit stuffing and unstuffing ■ Checksum generation and checking System Initialization ■ TOKEN type identification ■ Address checking. On power-up, the CY7C65620/CY7C65630 reads an external SPI EEPROM for configuration information. At the most basic level, this EEPROM has the vendor ID (VID), product ID (PID), and device ID (DID) for the customer’s application. For more specialized applications, other configuration options can be specified. See Configuration Options on page 13 for more details. Hub Repeater The hub repeater manages the connectivity between upstream and downstream facing ports that are operating at the same speed. It supports full- or low-speed connectivity and high-speed connectivity. According to the USB 2.0 specification, the HUB Repeater provides the following functions: ■ Sets up and tears down connectivity on packet boundaries ■ Ensures orderly entry into and out of the suspend state, including proper handling of remote wakeups. 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 facing port determines whether the routing logic connects a port to the TT or hub repeater. If a full- or low-speed device is connected to the hub operating at high-speed, the data transfer route includes the TT. If a high-speed device is connected to this high-speed hub, Document Number: 38-08037 Rev. *Z After reading the EEPROM, if VBUSPOWER (connected to upstream VBUS) is high, CY7C65620/CY7C65630 enables the pull-up resistor on D+ to indicate its presence to the upstream hub, after which a USB bus reset is expected. During this reset, CY7C65620/CY7C65630 initiates a chirp to indicate that it is a high-speed peripheral. In a USB 2.0 system, the upstream hub responds with a chirp sequence, and CY7C65620/CY7C65630 is in a high-speed mode, with the upstream D+ pull-up resistor turned off. In USB 1.x systems, no such chirp sequence from the upstream hub is seen, and CY7C65620/CY7C65630 operates as a normal 1.x hub (operating at full-speed). Enumeration After a USB bus reset, CY7C65620/CY7C65630 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. Page 4 of 30 CY7C65620 CY7C65630 Downstream Ports The CY7C65620/CY7C65630 supports a maximum of four downstream ports, each of which may be marked as usable or removable in the extended configuration (0xD2 EEPROM load or 0xD4 EEPROM load, see Configuration Options on page 13. Downstream D+ and D– pull-down resistors are incorporated in CY7C65620/CY7C65630 for each port. Before the hubs are configured, the ports are driven SE0 (single ended zero, 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: ■ Performs a USB reset on the corresponding port ■ Puts the port in an enabled state ■ Enables the green port indicator for that port (if not previously overridden by the host) ■ Enables babble detection after the port is enabled. 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. 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. Power Switching The CY7C65620/CY7C65630 includes interface signals for external port power switches. Both ganged and individual (per-port) configurations are supported, with individual switching being the default. Initially all ports are unpowered. After enumerating, the host may power each port by sending a SetPortPower request for that port. The power switching and overcurrent detection of downstream ports is managed by control pins connected to an external power switch device. PWR Document Number: 38-08037 Rev. *Z [n]# output pins of the CY7C65620/CY7C65630 series are connected to the respective external power switch's port power enable signals. Note that each port power output pin of the external power switch must be bypassed with an electrolytic or tantalum capacitor as required by the USB specification. These capacitors supply the inrush currents, which occur during downstream device hot-attach events. The polarity of this pin is configured through the EEPROM; see Configuration Options on page 13. Overcurrent Detection Overcurrent detection includes 8 ms of timed filtering by default. This parameter is configured from the external EEPROM in a range of 0 ms to 15 ms for both enabled ports and disabled ports individually. Detection of overcurrent on downstream ports is managed by control pins connected to an external power switch device. The OVR[n]# pins of the CY7C65620/CY7C65630 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# output to the external power device. The polarity of the OVR pins can be configured through the EEPROM; see Configuration Options on page 13. Port Indicators The USB 2.0 port indicators are also supported directly by CY7C65620/CY7C65630. 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 CY7C65620/CY7C65630 descriptor specifies that port indicators are supported (wHubCharacteristics, bit 7 is set). If port indicators are not included in the hub, disable this bit through EEPROM settings. Each port indicator pin is strategically located directly on the opposite edge of the port with which it is associated. A port indicator provides two colors: green and amber. This is usually implemented as two separate LEDs, one amber and the other green. A combination of hardware and software control is used to inform the user of the current status of the port or the device attached to the port and to guide the user through problem resolution. Colors and blinking provide information to the user. The significance of the color of the LED depends on the operational mode of CY7C65620/CY7C65630. The CY7C65620/CY7C65630 port indicators has two modes of operation: automatic and manual. On power up the CY7C65620/CY7C65630 defaults to automatic mode, where the color of the Port Indicator (green, amber, off) indicates the functional status of the CY7C65620/CY7C65630 port. In automatic mode, the CY7C65620/CY7C65630 turns on the green LED whenever the port is enabled and the amber LED when an overcurrent condition is detected. The color of the port indicator is set by the port state machine. Blinking of the LEDs is not supported in automatic mode. Table 1 identifies the mapping of color to port state in automatic mode. Page 5 of 30 CY7C65620 CY7C65630 Table 1. Automatic Port State to Port Indicator Color Mapping Downstream Facing Hub Port State Color Definition Port State Off or Amber, if due to an overcurrent condition Powered Off Off Disconnected, Disabled, Not Configured, Resetting, Testing Green Off Enabled, Transmit, or TransmitR Suspended, Resuming, SendEOR, Restart_E/S The LED control lines can also be modulated with a square wave for power conservation. The polarity of these pins is programmable, see Configuration Options on page 13. In manual mode, the indicators are under the control of the host, which can turn on the LEDs, or leave them off. This is done by a USB Hub class request. Blinking of the LEDs is supported in manual mode. The port indicators enable the user to intervene in any error detection. For example, when babble is detected while plugging in a defective device, or when an overcurrent condition occurs, the port indicators corresponding to the downstream port blink green or only light the amber LED, respectively. Table 2 displays the color definition of the indicators when CY7C65620/CY7C65630 is in manual mode.[1] Table 2.

Page 9 of 30 CY7C65620 CY7C65630 Default Descriptors This section presents the different descriptors that are available. The following tables list the functionality of each descriptor. Device Descriptor The standard device descriptor for CY7C65620/CY7C65630 is based on the information found in the SPI EEPROM. The information in the EEPROM overrides the default descriptor values. If no EEPROM is used, the CY7C65620/CY7C65630 enumerates with the default descriptor values as shown in the following table. If a blank EEPROM is connected, the hub enumerates as vendor defined class instead of a hub class. This is for the purpose of programming the EEPROM with the Cypress driver.

Document Number: 38-08037 Rev. *Z Page 12 of 30 CY7C65620 CY7C65630 Configuration Options Systems using CY7C65620/CY7C65630 have the option of using a fuse ROM, which is preset at the factory to configure the hub. Otherwise, it must have an external EEPROM for the device to have a unique VID, PID, and DID. The CY7C65620/CY7C65630 can communicate with SPI EEPROM that are either double byte addressed or single byte with the ninth bit within the instruction byte, such as the 24LC040 parts use. The 25LC080 EEPROM uses the double byte address format. Therefore, the CY7C65620/CY7C65630 can communicate with these parts. The '010s and '020s use the same command format that is used to interface with the ‘040 and hence these can also be used to interface with the CY7C65620/CY7C65630. If the attached EEPROM is blank (0xFF) the hub enumerates as a vendor class device. In this configuration, the hub connects to the Cypress driver to allow programming of the EEPROM. When the EEPROM is programmed, a power cycle configures the chip as a hub class device. With this EEPROM format, only a unique VID, PID, and DID must be present in the external SPI EEPROM. The contents of the EEPROM must contain this information in the following format: Byte Value 0xD0 1 VID (LSB) 2 VID (MSB) 3 PID (LSB) 4 PID (MSB) 5 reserved 6 DID (MSB) Least significant byte of vendor ID Byte 2: VID (MSB) Most significant byte of vendor ID Byte 3: PID (LSB) Least significant byte of product ID Byte 4: PID (MSB)] Most significant byte of product ID Byte 5: Reserved Reserved Byte 6: DID (MSB)] Most significant byte of device ID Count time in ms for filtering overcurrent detection. Bits 7–4 are for an enabled port, and bits 3–0 are for a disabled port. Both range from 0 ms to 15 ms. See Port Indicators on page 5. Default: 8 ms = 0x88. Byte 8: ActivePorts[3:0], RemovablePorts[3:0] Bits 7–4 are the ActivePorts[3:0] bits that indicates if the corresponding port is usable. For example, a two-port hub that uses ports 1 and 4 would set this field to 0x09. The total number of ports reported in the Hub Descriptor: bNbrPorts field is calculated from this. Bits 3–0 are the RemovablePorts[3:0] bits that indicates whether the corresponding logical port is removable (set to high). Logical port numbers are from 1 to n where n is the total number of active ports. If port 2 is disabled then physical ports 1, 3, and 4 map to logical ports 1, 2, and 3. These bit values are reported appropriately in the HubDescriptor:DeviceRemovable field.

Part Numbers Affected Part Number Device Characteristics CY7C65620 All Packages CY7C65630 All Packages HX2LP Qualification Status Product status: Production HX2LP Errata Summary 1. Non-periodic and Isochronous OUT transfers in the same microframe ■ Description With the operating in High-Speed mode with a Full-Speed device connected to a downstream port, Sometimes, an Isochronous OUT packet gets corrupted on the downstream port. ■ Implication The main cause of this phenomenon is in the way the hub's Transaction Translator downstream handler state machine schedules transactions if non-periodic (Control or Bulk) transactions are found in the non-periodic buffer while an Isochronous OUT transaction is active on the port. If the downstream handler state machine sees an Isochronous OUT packet in the Transaction translation buffer and if it is scheduled in the same micro-frame by the host then it will skip the Isochronous OUT transaction and resume a non-periodic transaction. ■ Workaround The workaround for this issue is for the host controller to avoid scheduling non-periodic traffic such that it will run while an Isochronous OUT transaction is active. Non-periodic traffic can be scheduled to run in the micro-frame before the Isochronous OUT transaction begins, or after the Isochronous OUT transaction completes. ■ Status No plan to fix currently - recommend using workaround. 2. Last data not received in multi-microframe Isochronous IN transfers ■ Description With the hub operating in High-Speed mode with a Full-Speed device connected to a downstream port, Sometimes a multi-microframe Isochronous IN transaction resulted in the last two Complete Split transactions that should have returned data but instead returned NYET handshakes. ■ Implication The main cause of this phenomenon is in the hub's Transaction Translator logic which tracks data stored in the periodic transaction buffer. If the Full-Speed transaction completes before the Complete-Split token is received from the host, there is a chance that buffer will be over-written if the requested Isochronous IN payload is greater than 440 bytes (USB 2.0 specification on buffer size). ■ Workaround The workaround for this issue is for the host controller to avoid scheduling the Complete Split token for the microframe where the Full-Speed packet ends too late in the frame. The TT is guaranteed to work correctly if the Complete Split is received in the first quarter of the microframe. ■ Status No plan to fix currently - recommend using workaround.
