USB251xB/xBi  
USB 2.0 Hi-Speed Hub Controller  
Datasheet  
PRODUCT FEATURES  
General Description  
Features  
The SMSC USB251xB/xBi hub is a family of low-power,  
configurable, MTT (multi transaction translator) hub  
controller IC products for embedded USB solutions. The  
x in the part number indicates the number of  
downstream ports available, while the B indicates  
battery charging support. 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 internal core voltage  
Onboard 24 MHz crystal driver or external 24 MHz  
clock input  
Highlights  
„
High performance, low-power, small footprint hub  
controller IC with 2, 3, or 4 downstream ports  
Fully compliant with the USB 2.0 Specification [1]  
Enhanced OEM configuration options available  
through either a single serial I2C® EEPROM, or  
SMBus slave port  
„
„
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  
Supports the USB Battery Charging specification  
Rev. 1.1 for Charging Downstream Ports (CDP)  
The USB251xB/xBi offers the following package:  
„
MultiTRAKTM  
—
High-performance multiple transaction translator which  
provides one transaction translator per port  
„
—
36-pin QFN (6x6 mm) lead-free RoHS compliant  
package  
„
„
PortMap  
—
Flexible port mapping and disable sequencing  
„
„
USB251xBi products support the industrial  
temperature range of -40ºC to +85ºC  
USB251xB products support the extended  
commercial temperature range of 0ºC to +85ºC  
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
