USB251xB/xBi

USB 2.0 Hi-Speed Hub Controller

PRODUCT FEATURES

General Description

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

in the part number indicates the number of

downstream ports available, while the

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.

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, or 4 downstream ports

Fully compliant with the

USB 2.0 Specification

[1]

Enhanced OEM configuration options available

through either a single serial I

EEPROM, or

SMBus slave port

MultiTRAK

PortMap

— 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

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

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)
