SIO10N268

The SIO10N268 is a single chip I/O device that can be used on the ISA or LPC bus. It is a 3.3V operational (5.0V tolerant), PC 99/2001, and ACPI 1.0 compliant Super I/O Controller.

This device includes SMSC’s true CMOS 765B floppy disk controller with advanced digital data separator and Multi-Mode parallel port with ChiProtectTM circuitry plus EPP and ECP support.

Implements the LPC bus interface when in LPC Mode. In this mode, the X-Bus Interface is enabled to interface to external I/O devices that have an 8-bit data bus and to standard ISA memory devices, up to 2MB, which can serve as BIOS flash. The I/O Address, DMA Channel and Hardware IRQ of each device in the part may be reprogrammed through the internal configuration registers.The SIO10N268 is a single chip I/O device that can be used on the ISA or LPC bus.
