Device Overview

Summary

The SCH5017 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface. It includes Hardware Monitoring capabilities, enhanced Security features, Power Control logic and Motherboard Glue logic.

Provides support for monitoring two external temperatures via thermal diode inputs and an internal sensor for measuring ambient temperature and allows for a two- or three-piece linear fan function. Complete legacy Super I/O functionality including a floppy disk controller with SMSC's true CMOS (Complementary Metal-Oxide-Semiconductor) 765B core and enhanced digital data separator are incorporated. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures and is software and register compatible with SMSC's proprietary 82077AA core. Additionally, it supports multiple low power-down modes and incorporates sophisticated power control circuitry.
