Revision 0.9 (09-28-06) SECURITY LEVEL SMSC EVB-USB2524

1 Overview

The SMSC USB2524 MultiSwitchTM is an USB2.0 compliant switching hub with two up-stream ports

and four down-stream ports. The EVB-USB2524 Evaluation Board demonstrates a stand alone

application for the switching hub with all the features listed below. Each of the down stream ports can

individually be assigned to up-stream port 1 or up-stream port 2. The port assignment can be

dynamically changed with user accessible switches individually for each port.

1.1 Features

Single Onboard +3.3V Regulator

LED status modes supported: USB, BASIC, and DUAL LED

Single Crystal Clock Source

Individual port over-current sensing

Individual port power control

High-speed, Full-speed, and Low-speed capable

Port Assignment interface

Port OCS/Port Power Control interface

Optional ESD and EMI footprints are provided

1.2 General Description

The EVB-USB2524 is a demonstration and evaluation platform featuring the USB2524 MultiSwitch

TM 4-port USB2.0

Switching Hub. It is designed to robustly demonstrate this unique device's features using a low-cost PCB

implementation.

The EVB-USB2524 features an on-board EEPROM for VID/PID/DID and configuration strings, such as switching

options, LED status options, and non-removable or disabled configuration for each port. The manufacturer, product

and serial strings for the hub can be changed in the EEPROM as well.

The EVB-USB2524 can also be configured through changing population of resistors to access internal “strapping

options”, without using the EEPROM.

The schematic for the EVB-USB2524 indicates which components are required for each configuration option.

2 Getting Started

2.1 Port Assignment

The EVB-USB2524 port assignments are selected by four level switches SW1 to SW4 located in the

upper right-hand corner. When only one up-stream port, “US 1” or “US 2” is connected to an

operational host, all down-stream ports will be assigned to that host. In this case the switches do not

have any effect. When both up-stream ports are connected to operational hosts “US 2” is selected with

switch in the bottom position and “US 1” with the switch in the top position. Figure 2.1 shows the

switches in detail.

Down-stream ports are numbered 1 through 4. The switches are labeled accordingly with the left-most

switch controlling down-stream port 1 and the right-most switch close to the supply connector

controlling down-stream port 4.
