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

• 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

General Features

• Programmable USB differential-pair pin location

• Hub Controller IC with 7 downstream ports

- Eases PCB layout by aligning USB signal

lines directly to connectors

• High-performance multiple transaction translator

MultiTRAK™ Technology provides one transac-

tion translator per port

• Programmable USB signal drive strength.

Recover USB signal integrity due to compromised

system environments using 4-level driving

strength resolution

• Enhanced OEM configuration options available

through either a single serial I²C EEPROM, or

SMBus Slave Port

• Select the presence of a permanently hardwired

USB peripheral device on a port by port basis

• 64-Pin (9x9 mm) QFN, RoHS compliant package

• Supports commercial (0ºC to +70ºC) and indus-

trial (-40ºC to +85ºC) temperature ranges

• Configure the delay time for filtering the over-cur-

rent sense inputs

• Configure the delay time for turning on down-

stream port power

Hardware Features

• Low power operation

• Indicate the maximum current that the 347-port

hub consumes from the USB upstream port

• Full Power Management with individual or ganged

power control of each downstream port

• Indicate the maximum current required for the hub

controller

• On-chip Power On Reset (POR)

• Internal 1.8V Voltage Regulator

• Support Custom String Descriptor up to 31 char-

acters in length for:

• Fully integrated USB termination and Pull-up/Pull-

down resistors

- Product String

• On Board 24MHz Crystal Driver, Resonator, or

External 24/MHz clock input

- Manufacturer String

- Serial Number String

• USB host/device speed indicator. Per-port 3-color

LED drivers indicate the speed of USB host and

device connection - hi-speed (480 Mbps), full-

speed (12 Mbps), low-speed (1.5 Mbps)

• Pin Selectable Options for Default Configuration

- Select Downstream Ports as Non-Removable

Ports

- Select Downstream Ports as Disabled Ports

• Enhanced EMI rejection and ESD protection per-

formance

- Select Downstream Port Power Control and

Over-Current Detection on a Ganged or Indi-

vidual Basis

- Select USB Signal Drive Strength

- Select USB Differential Pair Pin location
