Hub Controller

General Description

The SMSC USB251x hub is a family of low-power, OEM

configurable, MTT (multi transaction translator)1 hub

controller IC products for embedded USB solutions. The

“x” in the part number indicates the number of

downstream ports available. The SMSC hub supports

low-speed, full-speed, and hi-speed (if operating as a hi-

speed hub) downstream devices on all of the enabled

downstream ports.

For a summary of the products documented in this

datasheet, please refer to the Chapter 1, "USB251x Hub

Family Differences Overview," on page 7.

Highlights

High performance, low-power, small footprint hub

controller IC with 2, 3, 4, or 7 downstream ports

(indicated by the “x” in the part number)

Fully compliant with the USB 2.0 specification

Enhanced OEM configuration options available

through either a single serial I2C® EEPROM, or

SMBus slave port

MultiTRAKTM

— High-performance multiple transaction translator which

provides one transaction translator per port

PortMap

— Flexible port mapping and disable sequencing

PortSwap

— Programmable USB differential-pair pin locations ease

PCB design by aligning USB signal lines directly to

connectors

PHYBoost

— Programmable USB signal drive strength for recovering

signal integrity using 4-level driving strength resolution

Features

Full power management with individual or ganged

power control of each downstream port

Fully integrated USB termination and pull-up/pull-

down resistors

Supports a single external 3.3 V supply source;

internal regulators provide 1.2 V or 1.8 V internal

core voltage

On-chip driver for 24 MHz crystal resonator or

external 24/48 MHz clock input

Customizable vendor ID, product ID, and device ID

ESD protection up to 4 kilovolts on all USB pins

Supports self- or bus-powered operation

USB251xB2 and USB251xBi products support the

USB Battery Charging specification

Lead-free RoHS compliant packages:

— 36-pin QFN (6x6 mm)

— 48-pin QFN (7x7 mm)

— 64-pin QFN (9x9 mm)

USB251xi, USB2512Ai, and USB251xBi products

support the industrial temperature range of -40ºC

to +85ºC

Applications

LCD monitors and TVs

Multi-function USB peripherals

PC motherboards

Set-top boxes, DVD players, DVR/PVR

Printers and scanners

PC media drive bay

Portable hub boxes

Mobile PC docking

Embedded systems

1.USB2512A/Ai only uses a single transaction translator.

2.USB251xB and USB251xBi products are not yet available.

The information in this datasheet regarding USB251xB/Bi

serves as a preliminary product preview.
