General Description

The SMSC LPC47N217 is a 3.3V PC 99, PC2001, and ACPI 2.0 compliant Super I/O Controller. The LPC47N217 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 LPC47N217 incorporates a 16C550A compatible UART and one Multi-Mode parallel port with ChiProtect™ circuitry plus EPP and ECP support. This device also offers a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI CLKRUN# support, relocatable configuration ports, and three DMA channel options.
