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. These three Product Families incorporate complete legacy Super I/O, including a floppy disk controller with Microchip's true CMOS 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 SCH3112 family supports multiple low power-down modes, and the ISA Plug-and-Play Standard register set (Version 1.0a).
