General Description
The SMSC LPC47N207 is a 3.3V PC 99 and ACPI 1.0 compliant Super I/O Controller.
The LPC47N207 implements the LPC interface with the LPC PortSwitch™ Interface.
The LPC PortSwitch Interface is a hot-switchable external Docking LPC interface.
The LPC47N207 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 incorporates an eight pin 16C550A compatible
UART. In addition, the LPC47N207 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 incorporates sophisticated power control
circuitry (PCC). The PCC supports multiple low power down modes.
The LPC47N207 also features Software Configurable Logic
(SCL) for ease of use. SCL allows programmable system configuration
of key functions such as the UARTs.
The LPC47N207 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
may be reprogrammed through the internal configuration registers.
There are 192 I/O address location options, a Serialized IRQ
interface, and three DMA channels.
