System Configurations
7.2.1
EEPROM
The USB224x can be configured via a 2-wire (I2C) EEPROM (512x8) flash device containing the
options for the USB224x. If an external configuration device does not exist the internal default values
will be used. If one of the external devices is used for configuration, the OEM can update the values
through the USB interface. The device will then “attach” to the upstream USB host.
The USBDM tool set is available in the USB224x/USB225x Card Reader software release package.
To download the software package from SMSC's website, please visit:
https://www2.smsc.com/mkt/CW_SFT_PUB.nsf/Agreements/OBJ+Card+Reader
to go to the OBJ Card Reader Software Download Agreement. Review the license, and if you agree,
check the "I agree" box and then select “Confirm”. You will then be able to download the
USB224x/USB225x Card reader combo release package zip file containing the USBDM tool set.
