USB 2.0 High-Speed 3-Port
Hub Controller
Datasheet
PRODUCT FEATURES
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 3-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
General Description
The SMSC 3-Port Hub is low power, OEM configurable,
MTT (multi transaction translator) hub controller IC with
3 downstream ports for embedded USB solutions. The
3-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 3-
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 3 downstream ports
High-performance multiple transaction translator
MultiTRAK™ Technology Provides one transaction
translator per port
Configure the delay time for turning on downstream
port power
Enhanced OEM configuration options available
through either a single serial i2C EEPROM, or
SMBus Slave Port
Configure the polarity of downstream port power
control signals
Indicate the maximum current that the 3-port hub
consumes from the USB upstream port
Indicate the maximum current required for the hub
controller
36-pin (6x6mm) and 48-Pin (7x7mm) QFN lead-free,
RoHS compliant packages
Footprint compatible with USB2514 and USB2512
(36-pin QFN) to provide designers with flexibility
regarding the quantity of USB expansion ports
utilized without redesign
Supports Custom String Descriptor up to 31
characters in length for:
