USER MANUAL
1 Overview
The SMSC USB2660 contains an Ultra Fast USB 2.0 Hub, Flash Media Controller, and Protocol Bridge
Combo. The EVB-USB2660/60i Evaluation Board demonstrates a standalone application for
developers of the following applications: Flash Media Card Reader/Writer, printers, desktop and mobile
PCs, consumer A/V, and flat panel displays, among others.
1.1
General Description
The EVB-USB2660/60i is an evaluation and demonstration platform featuring the USB2660/60i Ultra
Fast USB 2.0 Hub, Flash Media Controller, and Protocol Bridge Combo on a 4-layer RoHS compliant
printed circuit board.
The EVB-USB2660/60i is designed to demonstrate the unique features of this device using a low-cost
PCB implementation with individual port power control for the downstream USB 2.0 ports. It is designed
to support internal default configuration settings and either an external I
2
C EEPROM (optional) for
customized configured functionality or SPI flash for customized configured functionality or for external
firmware. A SPI flash device is populated on the evaluation board to provide firmware updates via USB
by using the SMSC provided USBDM utility, as required.
Default configuration can be changed by adding an EEPROM into the provided footprint. However, the
SPI flash device has to first be removed to avoid signaling conflicts.
