General Description

The SMSC LPC47N217N is a 3.3V PC 99, PC2001, and ACPI 2.0 compliant Super I/O Controller. The LPC47N217N implements the LPC interface, a pin reduced ISA interface which provides the same or better performance as the ISA/X-bus with a substantial savings in pins used. The part also includes 14 GPIO pins.

The LPC47N217N incorporates a 16C550A compatible UART and one Multi-Mode parallel port with

ChiProtect? circuitry plus EPP and ECP support. The LPC47N217N is easy to use and offers lower

system cost and reduced board area.
