cy7c65620/cy7c65630 document number: 38-08037 rev. *t page 4 of 29 introduction ez-usb hx2lp? is cypress?s next generation family of high-performance, low-power usb 2.0 hub controllers. hx2lp is an ultra low power single chip usb 2.0 hub controller with integrated upstream and downstrea m transceivers, a usb serial interface engine (sie), usb hub co ntrol and repeater logic, and tt logic. cypress has also in tegrated many of the external passive components, such as pu ll-up and pull-down resistors, reducing the overall bill of materials required to implement a hub design. the hx2lp portfolio consists of: cy7c65630: 4-port/single transaction translator 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. 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. bit stuffing and unstuffing checksum generation and checking token type identification address checking. hub repeater the hub repeater manages the connectivity between upstream and downstream facing ports t hat 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 connec ts 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, 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 upstre am 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 motherboard hubs monitor hubs advanced port replicators docking stations split-pc designs external personal storage drives keyboard hubs
cy7c65620/cy7c65630 document number: 38-08037 rev. *t page 5 of 29 functional overview the cypress cy7c65620/cy7c65630 usb 2.0 hubs are high performance, low system co st 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. system initialization on power-up, the cy7c65620/cy7c65630 reads an external spi eeprom for configuration information. at the most basic level, this eeprom has the vendo r 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 14 for more details. after reading the eeprom, if vbuspower (connected to up-stream v bus ) 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 chir p to indicate that it is a high-speed peripheral. in a usb 2.0 system, the upstream hub responds with a chirp sequenc e, 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 (c onfiguration 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. 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 co nfiguration (0xd2 eeprom load or 0xd4 eeprom load, see configuration options on page 14 . downstream d+ and d? pull-dow n 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 configur ed, 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 co ndition 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 tr ansmitter 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 th is 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 supp orted, with individual switching being the default. initially a ll 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 dow nstream ports is managed by control pins connected to an exte rnal power switch device. pwr [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 specif ication. these capacitors supply the inrush currents, which occur during downstream device hot-attach event s. the polarity of this pin is configured through the eeprom; see configuration options on page 14 . 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
cy7c65620/cy7c65630 document number: 38-08037 rev. *t page 6 of 29 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 14 .
cy7c65620/cy7c65630 document number: 38-08037 rev. *t page 7 of 29 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 por t indicators are supported (whubcharacteristics, bit 7 is se t). 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 wh ich 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. ta b l e 1 identifies the mapping of color to port state in automatic mode. 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 14 . in manual mode, the indicators are under the control of the host, which can turn on the leds, or leav e 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. ta b l e 2 displays the color definition of the indicators when cy7c65620/cy7c65630 is in manual mode.
