PRODUCT FEATURES

General Description

Features

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

configurable, MTT (multi transaction translator)¹hub

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.

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

USB251xB²and USB251xBi products support the

USB Battery Charging specification

For a summary of the products documented in this

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

Family Differences Overview," on page 7.

Lead-free RoHS compliant packages:

Highlights

—

36-pin QFN (6x6 mm)

48-pin QFN (7x7 mm)

64-pin QFN (9x9 mm)

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

USB251xi, USB2512Ai, and USB251xBi products
