Datasheet  
PRODUCT FEATURES  
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.  
„
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  
„
„
„
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)  
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  
„
„
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)  
„
MultiTRAKTM  
—
High-performance multiple transaction translator which  
provides one transaction translator per port  
„
„
USB251xi, USB2512Ai, and USB251xBi products  
support the industrial temperature range of -40ºC  
to +85ºC  
USB251xB products support the extended  
commercial temperature range of 0ºC to +85ºC  
„
„
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  
Applications  
„
PHYBoost  
—
Programmable USB signal drive strength for recovering  
signal integrity using 4-level driving strength resolution
