PRODUCT FEATURES

USB2412

2-Port USB 2.0 Hi-Speed

Hub Controller

General Description

The SMSC USB2412 hub is a low-power, single

transaction translator (STT) hub controller IC with two

downstream ports for embedded USB applications. The

SMSC hub controller supports low-speed, full-speed,

and hi-speed (if operating as a hi-speed hub)

downstream devices on all of the enabled downstream

ports.

Features

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 internal core voltage

On-chip 24 MHz crystal and ceramic resonator driver

or external 24 MHz clock input

ESD protection up to 4 kilovolts on all USB pins

Supports self-powered operation

Contains a built-in default configuration; no external

configuration options or components are required

Downstream ports as optional non-removable ports

Supports compound devices on a port-by-port basis

28-pin QFN (5 x 5 mm) lead-free RoHS compliant

package

Supports the commercial temperature range:

0ºC to +70ºC

Highlights

High performance, low-power, small footprint hub

controller IC with two downstream ports
