Device Overview

Summary

The SCH5027 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.

There are four analog inputs for monitoring external voltages, and internal monitoring of the SIO’s VCC (emulated power well), VTR (signal power well), and VBAT power supplies. It can also monitor two external diodes, one internal ambient temperature sensor or retrieving temperatures from external processors that implement the PECI (Platform Environment Control Interface).

Complete legacy Super I/O functionality including a floppy disk controller with SMSC's true CMOS 765B core and enhanced digital data separator are incorporated. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT 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 and allows for a two- or three-piece linear fan function.
