Description

The GM82C803CN is a single 100-pin PC95 compatible Super I/O chip with a Floppy Disk Controller with data separator, two UARTs (GM16C550) and an infrared interface, one Parallel port (IEEE 1284 Compliant). The GM82C803CN is optimized for motherboard applications. The GM82C803CN also includes one game port selection, IDE interface and an address decoder for on-chip function. The Floppy Disk Control part provides all the needed functionality between the host processor peripheral bus and the cable connector to the Floppy Disk Driver. It integrates the selection, clock generation and high current drivers and supports the 4 MB drive as well as the other standard drives. The UARTs on GM82C803CN are compatible with the 16C550. One UART (COM2) includes Serial Infrared Interface, complying with IrDA, HPSIR, and ASKIR streams. The Configuration register is used to allocate the I/O Base Address IRQ or DMA for each corresponding function.
