The SCH5127 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface, and 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, and can alert the system to out-of-limit conditions and automatically control the speeds of multiple fans.
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 (Complementary Metal-Oxide-Semicond
uctor) 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.
