Device Overview

Summary

The LPC47M102 (AMI Keyboard BIOS Version of the LPC47M10x) is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. The LPC47M102 provides fan control through two fan speed control output pins and two fan tachometer input pins.The LPC47M102 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 LPC47M102 incorporates sophisticated power control circuitry (PCC) which includes support for keyboard and mouse wake-up events and supports multiple low power-down modes. The LPC47M102 provides the recommended functionality to support Windows '95. The I/O Address, DMA Channel and hardware IRQ of each logical device in the LPC47M102 may be reprogrammed through the internal configuration registers. There are 480 I/O address location options, a Serialized IRQ interface, and three DMA channels.
