The SCH3106 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliant Super I/O controller with an LPC interface as well as Hardware Monitoring capabilities, enhanced Security features, Power Control logic and Motherboard Glue logic. It incorporates complete legacy Super I/O functionality, including a floppy disk controller with SMSC'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 SMSC's proprietary 82077AA core. The hardware monitoring capability includes temperature, voltage and fan speed monitoring. It can alert the system of out-of-limit conditions and automatically control the speeds of multiple fans and includes support for monitoring two external temperatures via thermal diode inputs and an internal sensor for measuring ambient temperature. The hardware monitoring capability also has programmable automatic FAN control.
