General Description
Features
The SMSC USB251x hub is a family of low-power, OEM
configurable, MTT (multi transaction translator)1 hub
controller IC products for embedded USB solutions. The
“x” in the part number indicates the number of
downstream ports available. The SMSC 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.
For a summary of the products documented in this
datasheet, please refer to the Chapter 1, "USB251x Hub
Family Differences Overview," on page 7.
Highlights
High performance, low-power, small footprint hub
controller IC with 2, 3, 4, or 7 downstream ports
(indicated by the “x” in the part number)
Fully compliant with the USB 2.0 specification
Enhanced OEM configuration options available
through either a single serial I2C® EEPROM, or
SMBus slave port
MultiTRAKTM
— High-performance multiple transaction translator which
provides one transaction translator per port
PortMap
— Flexible port mapping and disable sequencing
PortSwap
— Programmable USB differential-pair pin locations ease
PCB design by aligning USB signal lines directly to
connectors
PHYBoost
— Programmable USB signal drive strength for recovering
signal integrity using 4-level driving strength resolution
Full power management with individual or ganged
power control of each downstream port
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 or 1.8 V internal
core voltage
On-chip driver for 24 MHz crystal resonator or
external 24/48 MHz clock input
Customizable vendor ID, product ID, and device ID
ESD protection up to 4 kilovolts on all USB pins
Supports self- or bus-powered operation
USB251xB2 and USB251xBi products support the
USB Battery Charging specification
Lead-free RoHS compliant packages:
— 36-pin QFN (6x6 mm)
— 48-pin QFN (7x7 mm)
— 64-pin QFN (9x9 mm)
USB251xi, USB2512Ai, and USB251xBi products
support the industrial temperature range of -40ºC
to +85ºC
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
1.USB2512A/Ai only uses a single transaction translator.
2.USB251xB and USB251xBi products are not yet available.
The information in this datasheet regarding USB251xB/Bi
serves as a preliminary product preview.
