General Description

The SMSC LPC47N207-JN is a 3.3V PC 99 and ACPI 1.0 compliant Super I/O Controller. The
LPC47N207-JN implements the LPC interface with the

LPC PortSwitch

Interface. T

LPC

PortSwitch

Interface is a hot-switchable external Docking LPC interface.

The LPC47N207-JN

also features a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI nCLKRUN
support, relocatable configuration ports and three DMA channel options. The part also includes 16 GPIO
pins.

The LPC47N207-JN incorporates an eight pin 16C550A compatible UART. In addition, the LPC47N207-
JN provides a second UART to support a Serial Infrared Interface that complies with IrDA v1.2 (Fast IR),
HPSIR, and ASKIR formats (used by Sharp and other PDAs), as well as Consumer IR.

The LPC47N207-JN incorporates sophisticated power control circuitry (PCC). The PCC supports multiple
low power down modes. The LPC47N207-JN also features Software Configurable Logic (SCL) for ease of
use. SCL allows programmable system configuration of key functions such as the UARTs.

The LPC47N207-JN supports the ISA Plug-and-Play Standard register set (Version 1.0a) and provides the
recommended functionality to support Windows `9x, 2K, ME, XP and PC99. The I/O Address, DMA
Channel and Hardware IRQ of each device in the LPC47N207-JN may be reprogrammed through the
internal configuration registers. There are 192 I/O address location options, a Serialized IRQ interface,
and three DMA channels.
