• Description: USB97C100 Multi-endpoint Usb Peripheral Controller(not Recommended For Designs)
• Manufacturer: Standard Microsystems Corporation

Applications
The USB97C100 enables entirely new I/O applications, as well as new form factors for existing Legacy I/O
applications. PC98 compliance encourages the elimination ofDMA, IRQ and addressing conflicts via total on-board
ISA elimination. With the USB97C100, the ISA bus can be eliminated from motherboards without sacrificing the
huge infrastructure of Legacy I/O ports. By moving these devices to the flexible USB bus, new form factors such as
monitor peripheral clusters are also possible (mouse, keyboard, serial, parallel ports in a USB connected monitor).
PC system designers are no longer constrained by the physical borders of the motherboard. The USB97C100 is
ideal for USB peripherals which require considerable bandwidth, such as floppy drives, audio, IR, etc. The following
block diagrams illustrate these applications.
