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
PortSwitch™ Interface is a hot-switchable external Docking LPC interface.
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 one 8-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.
