3 / 4 page LPC Super I/O IrDA Hot Docking Chip with UART SMSC LPC47N207 3 Revision 0.31 (09-21-06) PRODUCT PREVIEW 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 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.
