The SCH3112/SCH3114/SCH3
116 Product Family is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface that also includes Hardware Monitoring capabilities, enhanced Security features, Power Control logic and Motherboard Glue logic. The system’s hardware monitoring capability includes temperature, voltage and fan speed monitoring. The Motherboard Glue logic includes various power management and system logic including generation of nRSMRST, a programmable Clock output, and reset generation, which include a watchdog timer. The SCH3112/SCH3114/SCH3
116 Product Family incorporates complete legacy Super I/O, including a floppy disk controller with Microchip's true CMOS (Complimentary Metal-Oxide-Semicond
uctor) 765B core and enhanced digital data separator. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures and is software and register compatible with Microchip's proprietary 82077AA core. The family supports multiple low power-down modes, and also supports the ISA Plug-and-Play Standard register set (Version 1.0a).
