CY7C65630

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.

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 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:

Applications

Typical applications for the HX2LP device family are:

■ Standalone hubs

■ 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.

■ Motherboard hubs

■ Monitor hubs

■ Advanced port replicators

■ Docking stations

■ 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.

■ Split-PC designs

■ External personal storage drives

■ Keyboard hubs

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.

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.

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.

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 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 14 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:

After reading the EEPROM, if VBUSPOWER (connected to

upstream 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 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).

■ 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,

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.

CY7C65620

CY7C65630

[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 14.

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 14.

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:

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 14.

■ 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.

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.

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.

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

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.

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.

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

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 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.

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.

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

Byte 0: 0xD2

Needs to be programmed with 0xD2

Byte 1: VID (LSB)

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.

Byte 3: PID (LSB)

Byte 4: PID (MSB)]

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.

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 transac-

tion 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-microf-

rame 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.
