I/O Controller LPC Controller 0.015A 100-Pin PQFP

The LPC47M112 is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. The LPC47M112 implements the LPC interface, provides fan control through two fan speed control output pins and two fan tachometer input pins. The LPC47M112 incorporates a keyboard interface, SMSC"s true CMOS 765B floppy disk controller, and Intelligent Power Management including PME support. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures in addition to providing data overflow and underflow protection. The parallel port is compatible with IEEE 1284, EPP, and ECP. The LPC47M112 incorporates sophisticated power control circuitry (PCC) which includes support for keyboard and mouse wake-up events and supports multiple low power-down modes. The LPC47M112 provides the recommended functionality to support Windows "95, Windows 98, Windows 2000 and Windows ME.
