evaluation board user manual revision 1.0 (11-20-09) 2 smsc usb82640 user manual 1 overview the smsc usb82640 evaluation board revision a cont ains an ultra fast usb 2.0 multi-format flash media controller and a usb hub combo. the usb82640 evaluation board (EVB-USB82640) demonstrates a standalone application platform for developers of the following applications: flash media card reader/writer, printers, desktop and mobi le pcs, consumer a/v, and flat panel displays. the usb82640 is compatible with the following: ? microsoft vista ? ? windows ? xp ? windows me ? windows 2000 sp4 ? apple ? os x ? linux ? mass storage class drivers 1.1 features ? 48-pin qfn (rohs compliant) package. ? supports these media types: ? secure digital (sd?) ? memory stick ? (ms) 4-bit/8-bit interfaces ? memory stick pro? ? memory stick pro-hg? ? multimediacard? (mmc) 4-bit/8-bit interfaces ? two usb 2.0 downstream hub ports with indi vidual port power and over-current sense. ? supports external configuration ? external spi flash for usb downloadable firmware. ? external i 2 c eeprom for configuration options. ? low cost 4-layer space saving design ? operates from a single voltage (+5.0 vdc, regulated) 'wall wart' external power supply. ? internal fet power switch for all media types. ? multiple led indicators ? activity led indicator ? card power led indicator ? optional +3.3 vdc power led indicator ? port power led ? test header for firmware development and debug. ? single crystal clock source ? single onboard +3.3 vdc regulator. 1.2 general description the EVB-USB82640 is a demonstration and evaluation plat form featuring the usb82640 ultra fast usb 2.0 multi- format flash media controller and the usb hub combo on a 4-layer rohs compliant printed circuit board. it is designed to support internal default settings and either an external i 2 c eeprom for customized functionality or spi flash for external firmware. an 8-mbit spi flash device is populated on the evaluat ion board to provide firmware updates via usb by using the smsc provided usbdm utility. default configuration can be changed by adding an eepr om into the provided footprint. however, the spi flash device has to first be removed to avoid signaling conflicts. figure 1.1, "top and bottom level silk screen and copper layers" shows the top and bottom level silk screen and copper layer.

evaluation board user manual smsc usb82640 5 revision 1.0 (11-20-09) user manual 2 getting started the EVB-USB82640 is configured by inte rnal default registers. in this configuration it operates as a usb 2.0 combo device with a three port usb hub (t wo external ports) and a flash media controller with smsc standard vid/pid/did settings. 2.1 configuration the EVB-USB82640 is designed for flexible configurat ion solutions. it demonstrates functionality with default internal register settings, usb host downloadable configuration eeprom, or usb host downloadable external firmware to a spi flash. 2.1.1 configuration s ource - internal default when the EVB-USB82640 does not detect an eeprom or a valid spi flash image upon power-up, the EVB-USB82640 uses inter nal default register settings; it sets the vend or id, product id, language id, and device id, and a few other choices from internal rom code. 2.1.2 configuration s ource - external eeprom upon power-up the evb-u sb82640 looks for an at tached eeprom on its i 2 c interface. the evb- usb82640 provides a footprint wh ere an external eeprom (embedded in a dfn8 package of type 24c04) can be soldered to customize the media c ontroller?s settings. the eeprom contains 512 bytes of user customizable settings. among the settings are vendor id, product id, and device id numbers. for details on the fiel ds please see the usb82640 softwa re release notes. to use the eeprom the spi flash chip u9 must first be removed. 2.1.3 configuration s ource - external spi flash the installed spi flash is initially blank. in this scenario the internal firmware will execute. external firmware updates can be downloaded via usb using the smsc utility usbdm to the spi flash. after downloading the EVB-USB82640 will execute out of the spi flash. 2.1.4 power source - self/bus powered the EVB-USB82640 supports both self- and bus-pow ered operation. by def ault the EVB-USB82640 is populated for bus-powered operation. refer to the table below for resistor population options to change the power source. 2.1.5 configuration source - usb upstream the eeprom supporting the usb82640 is configur ed via a usb cable connected to the upstream connector with a smsc configuration tool named usbdm, see usb82640 software release notes for details. usbdm allows for modification of vendor id, product id, language id, device id, and configuration settings see figure 2.1, "usbdm configuration interface" . table 2.1 population options for self- or bus-powered operation power source r63 bus-powered populate self-powered (default) do not populate
