SMSC DS – USB97CFDC
Page 3
Rev. 12/15/2000
GENERAL DESCRIPTION
The USB97CFDC is an integration of the USB97C102 Enhanced Multi-Endpoint USB Peripheral Controller, without
its integrated hub functions, and the SMSC Floppy Disk Controller used in many of its Super IO products, such as
the FDC37C869. Special care in the interconnection of the two devices has been taken to assure the lowest possible
system current draw (<300A) during SUSPEND mode operation.
Provisions for external Flash Memory up to 32K bytes for program storage is provided.
Although not required for standard floppy operation, provisions for 16K bytes of external buffer SRAM, in addition to
that included in the USB97C102 core, is also provided for extended applications, such as tape drives and for other
special applications.
Several pins are provided for controlling external power control elements and sensing specialized drive functions.
Note:
SMSC has developed and supplies firmware and drivers for this device to implement a standard three mode
or dual mode Floppy Disk Drive system with drive power control. If the customer desires to develop his own
firmware and/or drivers for this system, he may contact SMSC to obtain a complete engineering
specification which details all the internal block functions and register maps of the USB97CFDC to allow
custom programs to be written for this device.
