Controller Interface 128-VTQFP (14x14)

Inquiry Add To Bom

SCH3106-NU General Description

TheSCH3106 is a 3.3V (Super I/O Block is 5V tolerant) PC99/PC2001 compliantSuper I/O controller with an LPC interface as well as Hardware Monitoringcapabilities, enhanced Security features, Power Control logic andMotherboard Glue logic.

Itincorporates complete legacy Super I/O functionality, including a floppydisk controller with SMSC's true CMOS 765B core and enhanced digitaldata separator. The true CMOS 765B core provides 100% compatibility withIBM PC/XTTM and PC/ATTM architectures and is softwareand register compatible with SMSC's proprietary 82077AA core.

Thehardware monitoring capability includes temperature, voltage and fan speedmonitoring. It can alert the system of out-of-limit conditions andautomatically control the speeds of multiple fans and includes support formonitoring two external temperatures via thermal diode inputs and aninternal sensor for measuring ambient temperature. The hardware monitoringcapability also has programmable automatic FAN control.
