Device Overview

Summary

The SCH5407 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 five analog inputs for monitoring external voltages, as well as internal monitoring of the SIO’s VCC (emulated power well), VTR (signal power well), and VBAT power supplies. The Motherboard Glue logic includes various power management and system logic including generation of nRSMRST, SMBus isolation buffers, and buffered PCI (Peripheral Component Interconnect) reset outputs. 

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/XTTM and PC/ATTM architectures and is software and register compatible with SMSC's proprietary 82077AA core.
