is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. It implements
the LPC interface, provides fan control through two fan speed control
output pins and two fan tachometer input pins. The product incorporates a
keyboard interface, SMSC's true CMOS 765B floppy disk controller, and
Intelligent Power Management including PME support.
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. LPC47M112 incorporates sophisticated power control
circuitry (PCC) which includes support for keyboard and mouse wake-up
events and supports multiple low power-down modes.
recommended functionality to support Windows '95, Windows 98, Windows 2000
and Windows ME is provided.
