SMSC USB2514 DATASHEET Revision 1.98 (11-19-07)
Datasheet
PRODUCT FEATURES
USB2514
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 USB2513 and USB2512
(36-pin QFN) to provide designers with flexibility
regarding the quantity of USB expansion ports
utilized without redesign
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
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
Applications
LCD monitors and TVs
Multi-function USB peripherals
PC mother boards
Set-top boxes, DVD players, DVR/PVR
Printers and scanners
PC media drive bay
Portable hub boxes
Mobile PC docking
Embedded systems
