PRODUCT FEATURES

USB2513i 

Industrial Temperature 
Rated USB 2.0 High-Speed 
3-Port Hub Controller

General Description

The SMSC 3-Port Hub is low power, OEM configurable,
MTT (multi transaction translator) hub controller IC with
3 downstream ports for embedded USB solutions.  The
3-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-/High-Speed Hub. The 3-
Port Hub supports Low-Speed, Full-Speed, and High-
Speed (if operating as a High-Speed Hub) downstream
devices on all of the enabled downstream ports.

General Features

„

Hub Controller IC with 3 downstream ports

„

High-performance multiple transaction translator 

MultiTRAK™ Technology Provides one transaction 
translator per port

„

Enhanced OEM configuration options available 

through either a single serial i2C EEPROM, or 
SMBus Slave Port

„

36-pin (6x6mm) and 48-Pin (7x7mm) QFN lead-free, 

RoHS compliant packages

„

Footprint compatible with USB2514i and USB2512i 

(36-pin QFN) to provide designers with flexibility 
regarding the quantity of USB expansion ports 
utilized without redesign

„

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 24/48MHz clock input

„

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

LED drivers that indicate the speed of USB host and 
device connection - hi-speed (480 Mbps), full-speed 
(12 Mbps), low-speed (1.5 Mbps) (48-pin QFN)

„

Enhanced EMI rejection and ESD protection 

performance

OEM Selectable Features

„

Customize 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/reordered in any order to support 
multiple product SKUs. 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 3-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

„

Configure the polarity of downstream port power 

control signals

„

Indicate the maximum current that the 3-port hub 

consumes from the USB upstream port

„

Indicate the maximum current required for the hub 

controller 

„

Supports Custom String Descriptor up to 31 

characters in length for:

Product String

Manufacturer String

Serial Number String

„

Pin Selectable Options for Default Configuration 

Select Downstream Ports as Non-Removable Ports 

Select Downstream Ports as Disabled Ports 

Select Downstream Port Power Control and Over-
Current Detection on a Ganged or Individual Basis 

Select Downstream Port Power Control Polarity

Select USB Signal Drive Strength

Select USB Differential Pair Pin location

Select on-chip or off-chip voltage regulator mode
