PRODUCT FEATURES

USB2512Ai

Industrial Temperature Rated

USB 2.0 Hi-Speed 2-Port Hub

Controller

General Description

The SMSC 2-Port Hub is a low power, OEM

configurable, STT (single transaction translator) Hub

controller IC with 2 downstream ports for embedded

USB solutions. The 2-port Hub is fully compliant with

the USB 2.0 Specification and will attach to an upstream

port as a Full-Speed Hub or as a Full-/Hi-Speed Hub.

The 2-Port 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.

General Features

 Hub Controller IC with 2 downstream ports

 Enhanced OEM configuration options available

through either a single serial I

C EEPROM, or

SMBus Slave Port

 36-pin (6x6mm) QFN lead-free RoHS compliant

package

 Supports industrial temperature range of -40ºC to

85ºC

Hardware Features

 Low power operation

 Full power management with individual or ganged

power control of each downstream port

 On-chip Power-On Reset (POR)

 Internal 1.8V Voltage Regulator

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

down resistors

 On Board 24MHz Crystal Driver, Resonator, or

External 24MHz clock input

 Enhanced EMI rejection and ESD protection

performance

OEM Selectable Features

 Customizable Vendor ID, Product ID, and Device ID

 Select whether the Hub is part of a compound device:

When any downstream port is permanently hardwired

to a USB peripheral device, the Hub is part of a

compound device

 Flexible port mapping and disable sequence: Ports

can be disabled or reordered in any order to support

multiple product SKUs. The Hub will automatically

reorder the remaining ports to match the Host

controller's numbering scheme.

 Programmable USB differential-pair pin location:

Ease PCB layout by aligning USB signal lines directly

to connectors

 Programmable USB signal drive strength: Recover

USB signal integrity due to compromised system

environment using 2-level driving strength resolution

 Select the presence of a permanently hardwired USB

peripheral device on a port-by-port basis

 Configure the delay time for filtering the over-current

sense inputs

 Configure the delay time for turning on downstream

port power

 Indicate the maximum current that the 2-port Hub

consumes from the USB upstream port

 Indicate the maximum current required for the Hub

controller

 Pin Selectable Option for Default Configuration:

Select Downstream Ports as Non-Removable Ports

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
