1.2 General Description

The EVB-USB2240-IND is a demonstration and evaluation platform featuring the USB2240 Media
Controller in a 2-layer RoHS compliant PCB. It is designed to support internal de fault settings and an
external EEPROM for customized functionality. The EVB-USB2240-IND can operate in self-powered
mode with an external power supply or in bus-powered mod e getting its +5V source fro m the upstream
connector. Default configuration can be changed by adding an EEPROM into the provided socket.
Footprints are available for optional features such as LED indicators. Figure 1.1 shows the top and
bottom level silk screen and copper layer. The EVB-USB2240-IND is compatible with Microsoft Vista,
Windows XP, Windows ME, Windows 2k SP4, Apple OSx and Linux Mass Storage Class Drivers.
