USB 2.0 Hi-Speed 7-Port Hub Controller

General Description

OEM Selectable Features

The 7-Port Hub is a low power, OEM configurable, MTT

(multi transaction translator) hub controller IC with 7

downstream ports for embedded USB solutions. The 7-

port hub is fully compliant with the USB 2.0 Specifica-

tion and will attach to an upstream port as a Full-Speed

Hub or as a Full-/Hi-Speed Hub. The 7-Port Hub sup-

ports Low-Speed, Full-Speed, and Hi-Speed (if operat-

ing as a Hi-Speed Hub) downstream devices on all of

the enabled downstream ports.

• Customizable Vendor ID, Product ID, and Device

ID

• Select whether the hub is part of a compound

device (When any downstream port is perma-

nently hardwired to a USB peripheral device, the

hub is part of a compound device.)

• Flexible port mapping and disable sequence.

Ports can be disabled/reordered in any order to

support multiple product SKUs. Hub will automati-

cally reorder the remaining ports to match the

Host controller's numbering scheme

PIN DESCRIPTIONS AND BUFFER TYPE DESCRIPTIONS

Pin Descriptions

This section provides a detailed description of each signal. The signals are arranged in functional groups according to

their associated interface.

The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage

level. When “N” is not present before the signal name, the signal is asserted when at the high voltage level.

The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of

“active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of

whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inac-

tive.

LED USAGE DESCRIPTION

LED Functionality

The hub supports 2 different (mutually exclusive) LED modes. The USB Mode provides 14 LED’s that conform to the

USB 2.0 specification functional requirements for Green and Amber LED’s. The LED Mode “Speed indicator” provides

the downstream device connection speed.

6.1.1

USB MODE 14-WIRE

The LED_A[7:1]_N pins are used to provide Green LED support as defined in the USB 2.0 specification. The

LED_B[7:1]_N pins are used to provide Amber LED support as defined in the USB 2.0 specification. The USB Specifi-

cation defines the LED’s as port status indicators for the downstream ports. Please note that no indication of port speed

is possible in this mode. The pins are utilized as follows:

• LED_A1_N = Port 1 green LED

• LED_A2_N = Port 2 green LED

• LED_A3_N = Port 3 green LED

• LED_A4_N = Port 4 green LED

• LED_A5_N = Port 5 green LED

• LED_A6_N = Port 6 green LED

• LED_A7_N = Port 7 green LED

• LED_B1_N = Port 1 amber LED

• LED_B2_N = Port 2 amber LED

• LED_B3_N = Port 3 amber LED

• LED_B4_N = Port 4 amber LED

• LED_B5_N = Port 5 amber LED

• LED_B6_N = Port 6 amber LED

• LED_B7_N = Port 7 amber LED

6.1.2

LED MODE SPEED INDICATION

The LED_A[7:1]_N pins are used to provide connection status as well as port speed by using dual color LED's. This

scheme requires that the LED's be in the same package, and that a third color is produced so that the user perceives

both LED's as being driven "simultaneously".

The LED_A[7:1] pins used in this mode are connected to 7 dual color LED’s (each LED pair in a single package). These

pins indicate the USB speed of each attached downstream device.

Each dual color LED provides two separate colors (commonly Green and Red). If each of these separate colors are

pulsed on and off at a rapid rate, a user will see a third color (in this example, Orange). Using this method, 4 different

"color" states are possible (Green, Red, Orange, and Off).

Figure 6-1 shows a simple example of how this LED circuit will be implemented. The circuit should be replicated for each

of the 7 LED pins on the HUB. In this circuit, when the LED pin is driven to a logic low state, the Green LED will light up.

When the LED pin is driven to a Logic High state the Red LED will light up. When a 1 KHz square wave is driven out on

the LED pin, the Green and Red LED's will both alternately light up giving the effect of the color Orange. When nothing

is driven out on the LED pin (i.e. the pin floats to a "tri-state" condition), neither the Green nor Red LED will light up, this

is the "Off" state.

The assignment is as follows:

• LED_A1_N = LED D1 (Downstream Port 1)

• LED_A2_N = LED D2 (Downstream Port 2)

• LED_A3_N = LED D3 (Downstream Port 3)

• LED_A4_N = LED D4 (Downstream Port 4)

• LED_A5_N = LED D5 (Downstream Port 5)

• LED_A6_N = LED D6 (Downstream Port 6)

• LED_A7_N = LED D7 (Downstream Port 7)

The usage is as follows:

• LED_Ax_N Driven to Logic Low = LS device attached (Green LED)

• LED_Ax_N Driven to Logic High = FS device attached (Red LED)

• LED_Ax_N Pulsed @ 1 KHz= HS device attached (Orange color by pulsing Red & Green).

• LED_Ax_N is tri-state= No devices are attached, or the hub is in suspend, LED's are off.

CONFIGURATION OPTIONS

7-Port Hub

The USB 2.0 7-Port Hub is fully compliant to the Universal Serial Bus Specification Revision 2.0 from April 27, 2000 (12/

7/2000 and 5/28/2002 Errata). Please reference Chapter 11 (Hub Specification) for general details regarding Hub oper-

ation and functionality.

For performance reasons, the 7-Port Hub provides 1 Transaction Translator (TT) per port (defined as Multi-TT configu-

ration), divided into 4 non-periodic buffers per TT.

7.1.1

HUB CONFIGURATION OPTIONS

The MCHP Hub supports a large number of features (some are mutually exclusive), and must be configured in order to

correctly function when attached to a USB host controller. There are three principal ways to configure the Hub: SMBus,

EEPROM, or by internal default settings (with or without pin strapping option overrides). In all cases, the configuration

method will be determined by the CFG_SEL2, CFG_SEL1 and CFG_SEL0 pins immediately after RESET_N negation.

7.1.1.1

Power Switching Polarity

Note:

The hub will support active high power controllers only!

7.1.2

VBUS DETECT

According to Section 7.2.1 of the USB 2.0 Specification, a downstream port can never provide power to its D+ or D- pull

up resistors unless the upstream port’s VBUS is in the asserted (powered) state. The VBUS_DET pin on the Hub mon-

itors the state of the upstream VBUS signal and will not pull up the D+ resistor if VBUS is not active. If VBUS goes from

an active to an inactive state (not powered), the Hub will remove power from the D+ pull up resistor within 10 seconds.

7.2

EEPROM Interface

The MCHP Hub can be configured via a 2-wire (I²C) EEPROM (256x8). (Please see Table 5-2, "USB2517I SMBUS or

EEPROM Interface Behavior" for specific details on how to enable configuration via an I²C EEPROM).

The internal state machine will (when configured for EEPROM support) read the external EEPROM for configuration

data. The Hub will then “attach” to the upstream USB host.

Note:

The Hub does not have the capacity to write, or “Program,” an external EEPROM. The Hub only has the

capability to read external EEPROMs. The external EEPROM will be read (even if it is blank or non-popu-

lated), and the Hub will be “configured” with the values that are read.

Please see Internal Register Set (Common to EEPROM and SMBus) for a list of data fields available.

SELF_BUS_PWR

Self or Bus Power: Selects between Self- and Bus-Powered operation.

The Hub is either Self-Powered (draws less than 2mA of upstream bus

power) or Bus-Powered (limited to a 100mA maximum of upstream power

prior to being configured by the host controller).

When configured as a Bus-Powered device, the MCHP Hub consumes less

than 100mA of current prior to being configured. After configuration, the Bus-

Powered MCHP Hub (along with all associated hub circuitry, any embedded

devices if part of a compound device, and 100mA per externally available

downstream port) must consume no more than 500mA of upstream VBUS

current. The current consumption is system dependent, and the OEM must

ensure that the USB 2.0 specifications are not violated.

When configured as a Self-Powered device, <1mA of upstream VBUS current

is consumed and all ports are available, with each port being capable of

sourcing 500mA of current.

This field is set by the OEM using either the SMBus or EEPROM interface

options.

Please see the description under Dynamic Power for the self/bus power func-

tionality when dynamic power switching is enabled.

0 = Bus-Powered operation

1 = Self-Powered operation

Note:

If Dynamic Power Switching is enabled, this bit is ignored and the

LOCAL_PWR pin is used to determine if the hub is operating from

self or bus power.

MTT_ENABLE

Multi-TT enable: Enables one transaction translator per port operation.

Selects between a mode where only one transaction translator is available for

all ports (Single-TT), or each port gets a dedicated transaction translator

(Multi-TT) {Note: The host may force single-TT mode only}.

0 = single TT for all ports

1 = one TT per port (multiple TT’s supported)

EOP_DISABLE

EOP Disable: Disables EOP generation of EOF1 when in Full-Speed mode.

During FS operation only, this permits the Hub to send EOP if no downstream

traffic is detected at EOF1. See Section 11.3.1 of the USB 2.0 Specification

for additional details. Note: generation of an EOP at the EOF1 point may pre-

vent a Host controller (operating in FS mode) from placing the USB bus in

suspend.

0 = EOP generation is normal

source is available, the Hub will always switch to Self-Powered operation.}

When Dynamic Power switching is enabled, the Hub detects the availability of

a local power source by monitoring the external LOCAL_PWR pin. If the Hub

detects a change in power source availability, the Hub immediately discon-

nects and removes power from all downstream devices and disconnects the

upstream port. The Hub will then re-attach to the upstream port as either a

7.2.2

I C EEPROM

The I²C EEPROM interface implements a subset of the I²C Master Specification (Please refer to the Philips Semicon-

ductor Standard I²C-Bus Specification for details on I²C bus protocols). The Hub’s I²C EEPROM interface is designed

to attach to a single “dedicated” I²C EEPROM, and conforms to the Standard-mode I²C Specification (100kbit/s transfer

rate and 7-bit addressing) for protocol and electrical compatibility.

Note:

Extensions to the I²C Specification are not supported.

The Hub acts as the master and generates the serial clock SCL, controls the bus access (determines which device acts

as the transmitter and which device acts as the receiver), and generates the START and STOP conditions.

7.2.2.1

Implementation Characteristics

The Hub will only access an EEPROM using the Sequential Read Protocol.

7.2.2.2

Pull-Up Resistor

The Circuit board designer is required to place external pull-up resistors (10K recommended) on the SDA/SMBDATA

& SCL/SMBCLK/CFG_SELO lines (per SMBus 1.0 Specification, and EEPROM manufacturer guidelines) to Vcc in

order to assure proper operation.

7.2.2.3

I C EEPROM Slave Address

Slave address is 1010000.

Note: 10-bit addressing is NOT supported.

7.2.3

IN-CIRCUIT EEPROM PROGRAMMING

The EEPROM can be programmed via ATE by pulling RESET_N low (which tri-states the Hub’s EEPROM interface and

allows an external source to program the EEPROM).

DS00001598C-page 38

 2013-2018 Microchip Technology Inc.

USB2517/USB2517I

7.3

SMBus Slave Interface

Instead of loading User-Defined Descriptor data from an external EEPROM, the MCHP Hub can be configured to

receive a code load from an external processor via an SMBus interface. The SMBus interface shares the same pins as

the EEPROM interface; if CFG_SEL1 & CFG_SEL0 activates the SMBus interface, external EEPROM support is no

longer available (and the user-defined descriptor data must be downloaded via the SMBus). Due to system issues, the

MCHP Hub waits indefinitely for the SMBus code load to complete and only “appears” as a newly connected device on

USB after the code load is complete.

The Hub’s SMBus implementation is a subset of the SMBus interface to the host. The device is a slave-only SMBus

device. The implementation in the device is a subset of SMBus since it only supports two protocols.

The Write Block and Read Block protocols are the only valid SMBus protocols for the Hub. The Hub responds to other

protocols as described in Section 7.3.2, "Invalid Protocol Response Behavior," on page 40. Reference the System Man-

agement Bus Specification, Rev 1.0.

The SMBus interface is used to read and write the registers in the device. The register set is shown in Section 7.2.1,

"Internal Register Set (Common to EEPROM and SMBus)," on page 19.

7.3.1

BUS PROTOCOLS

Typical Write Block and Read Block protocols are shown below. Register accesses are performed using 7-bit slave

addressing, an 8-bit register address field, and an 8-bit data field. The shading indicates the Hub driving data on the

SMBDATA line; otherwise, host data is on the SDA/SMBDATA line.

The slave address is the unique SMBus Interface Address for the Hub that identifies it on SMBus. The register address

field is the internal address of the register to be accessed. The register data field is the data that the host is attempting

to write to the register or the contents of the register that the host is attempting to read.

Note:

Data bytes are transferred MSB first (msb first).

7.3.1.1

Block Read/Write

The Block Write begins with a slave address and a write condition. After the command code, the host issues a byte

count which describes how many more bytes will follow in the message. If a slave had 20 bytes to send, the first byte

would be the number 20 (14h), followed by the 20 bytes of data. The byte count may not be 0. A Block Read or Write is

allowed to transfer a maximum of 32 data bytes.

INVALID PROTOCOL RESPONSE BEHAVIOR

Registers accessed with an invalid protocol are not updated. A register is only updated following a valid protocol. The

only valid protocols are Write Block and Read Block, which are described above.

The Hub only responds to the hardware selected Slave Address.

Attempting to communicate with the Hub over SMBus with an invalid slave address or invalid protocol results in no

response, and the SMBus Slave Interface returns to the idle state.

The only valid registers that are accessible by the SMBus slave address are the registers defined in the Registers Sec-

tion. See Section 7.3.3 for the response to undefined registers.

7.3.3

GENERAL CALL ADDRESS RESPONSE

The Hub does not respond to a general call address of 0000_000b.

DS00001598C-page 40

 2013-2018 Microchip Technology Inc.

USB2517/USB2517I

7.3.4

SLAVE DEVICE TIME-OUT

According to the SMBus Specification, V1.0 devices in a transfer can abort the transfer in progress and release the bus

when any single clock low interval exceeds 25ms (T_{TIMEOUT, MIN}). Devices that have detected this condition must reset

their communication and be able to receive a new START condition no later than 35ms (T_{TIMEOUT, MAX}).

Note:

Some simple devices do not contain a clock low drive circuit; this simple kind of device typically resets its

communications port after a start or stop condition. The Slave Device Time-Out must be implemented.

7.3.5

STRETCHING THE SCLK SIGNAL

The Hub supports stretching of the SCLK by other devices on the SMBus. The Hub does not stretch the SCLK.

7.3.6 SMBUS TIMING

The SMBus Slave Interface complies with the SMBus AC Timing Specification. See the SMBus timing in the “Timing

Diagram” section.

7.3.7

BUS RESET SEQUENCE

The SMBus Slave Interface resets and returns to the idle state upon a START field followed immediately by a STOP

field.

7.3.8

SMBUS ALERT RESPONSE ADDRESS

The SMBALERT# signal is not supported by the Hub.

7.3.8.1

Undefined Registers

The registers shown in Table 7-1 are the defined registers in the Hub. Reads to undefined registers return to 00h. Writes

to undefined registers have no effect and do not return an error.

7.3.8.2

Reserved Registers

Unless otherwise instructed, only a ‘0’ may be written to all reserved registers or bits.

7.4

Default Configuration Option

The MCHP Hub can be configured via its internal default configuration. (Please see Section 7.2.1, "Internal Register Set

(Common to EEPROM and SMBus)" for specific details on how to enable default configuration.)

Please refer to Table 7-1 for the internal default values that are loaded when this option is selected.

7.5

Default Strapping Options:

The USB2517/USB2517I can be configured via a combination of internal default values and pin strap options. Please

see Table 5-1, "USB2517/USB2517I Pin Descriptions" and Table 5-2, "USB2517I SMBUS or EEPROM Interface

Behavior" for specific details on how to enable the default/pin-strap configuration option.

The strapping option pins only cover a limited sub-set of the configuration options. The internal default values will be

used for the bits & registers that are not controlled by a strapping option pin. Please refer to Table 7-1 for the internal

default values that are loaded when this option is selected.

The Amber and Green LED pins are sampled after RESET_N negation, and the logic values are used to configure the

hub if the internal default configuration mode is selected. The implementation shown below (see Section 7.6, "Reset")

shows a recommended passive scheme. When a pin is configured with a “Strap High” configuration, the LED functions

with active low signalling, and the PAD will “sink” the current from the external supply. When a pin is configured with a

“Strap Low” configuration, the LED functions with active high signalling, and the PAD will “source” the current to the

external LED.

A valid hardware reset is defined as assertion of RESET_N for a minimum of 1us after all power supplies are within

operating range. While reset is asserted, the Hub (and its associated external circuitry) consumes less than 500A of

current from the upstream USB power source.

Assertion of RESET_N (external pin) causes the following:

1. All downstream ports are disabled, and PRTPWR power to downstream devices is removed.

2. The PHYs are disabled, and the differential pairs will be in a high-impedance state.

3. All transactions immediately terminate; no states are saved.

4. All internal registers return to the default state (in most cases, 00(h)).

5. The external crystal oscillator is halted.

6. The PLL is halted.

7. LED indicators are disabled.

The Hub is “operational” 500s after RESET_N is negated.

Once operational, the Hub immediately reads OEM-specific data from the external EEPROM (if the SMBus option is not

disabled).

USB BUS RESET

In response to the upstream port signaling a reset to the Hub, the Hub does the following:

Note:

The Hub does not propagate the upstream USB reset to downstream devices.

1. Sets default address to 0.

2. Sets configuration to: Unconfigured.

1. Negates PRTPWR[7:1] to all downstream ports.

2. Clears all TT buffers.

3. Moves device from suspended to active (if suspended).

4. Complies with Section 11.10 of the USB 2.0 Specification for behavior after completion of the reset

sequence.

The Host then configures the Hub and the Hub’s downstream port devices in accordance with the USB Specification.

Note:

Stresses above the specified parameters could cause permanent damage to the device. This is a stress

rating only and functional operation of the device at any condition above those indicated in the operation

sections of this specification is not implied.

When powering this device from laboratory or system power supplies, it is important that the Absolute Max-

imum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on

their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line

may appear on the DC output. When this possibility exists, it is suggested that a clamp circuit be used.

Note the following details of the code protection feature on Microchip devices:

•

Microchip products meet the specification contained in their particular Microchip Data Sheet.

•

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

•

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

•

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be

superseded by updates. It is your responsibility to ensure that your application meets with your specifications. MICROCHIP MAKES NO
