PRODUCT FEATURES

USB2514i

Industrial Temperature

Rated USB 2.0 High-Speed

4-Port Hub Controller

General Description

The SMSC 4-Port Hub is low power, OEM configurable,

MTT (multi transaction translator) hub controller IC with

4 downstream ports for embedded USB solutions. The

4-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 4-

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 4 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 USB2513i 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 4-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 4-port hub

consumes from the USB upstream port

Indicate the maximum current required for the hub

controller
