GENERAL DESCRIPTION
The USB97CFDC2-01 is an integration of an Enhanced Multi-Endpoint USB 1.1 Peripheral Controller, a 32K Byte
Program ROM, and the SMSC Floppy Disk Controller used in many of its Super IO products, such as the
FDC37C869. Special care in the design has been taken to assure the lowest possible system current draw (<250µA)
during SUSPEND mode operation.
Provisions for external program Flash Memory up to 32K bytes for program storage is provided for customized
applications.
Several pins are provided for controlling external power control elements and sensing specialized drive functions.
Individual manufacturers may provide their unique USB vendor and product IDs and descriptor strings via an external
3 wire serial EEPROM. Up to 16 different configuration options for various drive related parameters are provided by 4
external configuration input pins which can be read at power-on reset.
