97CFDC Product details

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 (<300µA) during SUSPEND mode operation.
