PRODUCT FEATURES
General Description
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.
Datasheet
Features
USB251xB/xBi products are fully footprint compatible
with USB251x/xi/xA/xAi products as direct drop-in
replacements
— Cost savings include using the same PCB components
and application of USB-IF Compliance by Similarity
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 I
2
C
®
EEPROM, or
SMBus slave port
MultiTRAK
TM
PortMap
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
Onboard 24 MHz crystal driver, ceramic resonator, or
external 24/48 MHz clock input
Customizable vendor ID, product ID, and device ID
4 kilovolts of HBM JESD22-A114F ESD protection
(powered and unpowered)
Supports self- or bus-powered operation
USB251xB and USB251xBi products support the
USB Battery Charging specification Rev. 1.1 for
Charging Downstream Ports (CDP)
Lead-free RoHS compliant packages:
— 36-pin QFN (6x6 mm)
— 48-pin QFN (7x7 mm)
— 64-pin QFN (9x9 mm)
— High-performance multiple transaction translator which
provides one transaction translator per port
— Flexible port mapping and disable sequencing
— Programmable USB differential-pair pin locations ease
PCB design by aligning USB signal lines directly to
connectors
— Programmable USB signal drive strength for recovering
signal integrity using 4-level driving strength resolution
PortSwap
USB251xi, USB2512Ai, and USB251xBi products
