Device Overview

Summary

The SMSC LPC47N267 is a 3.3V PC 99 and ACPI 1.0 compliant Super I/O Controller. This part includes LPC and X- Bus interfaces; the latter may be accessed through the LPC interface for supported I/O cycles (memory cycles are not supported by this device). The X-Bus interface supports as many as four external components and it offers three different modes of operation for interfacing with these components. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures and provides data overflow and underflow protection. The SMSC advanced digital data separator incorporates SMSC’s patented data separator technology allowing for ease of testing and use. The LPC47N267 supports both 1Mbps and 2Mbps data rates and vertical recording operation at 1Mbps Data Rate. The LPC47N267 also features a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI nCLKRUN support and relocatable configuration. One UART includes additional support for a Serial Infrared Interface that complies with IrDA v1.2 (Fast Infrared), HPSIR, and ASKIR formats (used by Sharp and other PDAs), as well as Consumer IR.The parallel port is compatible with IEEE 1284, EPP and ECP.  The LPC47N267 incorporates sophisticated power control circuitry (PCC), which supports multiple low power down modes.
