56-Pin Super I/O with LPC Interface
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
13 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.
The LPC47N217N 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.
The parallel port is compatible with IBM PC/AT architectures, as well as IEEE 1284 EPP and ECP. The
parallel port ChiProtect™ circuitry prevents damage caused by an attached powered printer when the
LPC47N217N is not powered.
The LPC47N217N features Software Configurable Logic (SCL) for ease of use. SCL allows
programmable system configuration of key functions such as the parallel port and UART.
The LPC47N217N supports the ISA Plug-and-Play Standard register set (Version 1.0a) and provides
the recommended functionality to support Windows operating systems, PC99, and PC2001. The I/O
Address, DMA Channel, and Hardware IRQ of each device in the LPC47N217N may be reprogrammed
through the internal configuration registers. There are multiple I/O address location options, a
Serialized IRQ interface, and three DMA channels.
