SCH5617C is a 3.3V PC 2001 compliant Super I/O controller with an LPC interface. All legacy drivers used for Super I/O components are supported, making this interface transparent to the supporting software. The LPC bus also supports power management, such as wake-up and sleep modes. This device provides temperature monitoring with auto fan control, and is capable of monitoring two external diodes, one internal ambient temperature sensor or retrieving temperatures from external processors that implement the PECI interface. Programmable automatic fan control based on one or more measured temperatures offered and has support for a PROCHOT_IN# pin and a separate PROCHOT_OUT pin. The GLUE Logic includes various power management logic including generation of RSMRST# and Power OK signal generation. Two floppy controllers use the true CMOS (Complementary Metal-Oxide-Semicond
uctor) 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures and is software and register compatible with SMSC's proprietary 82077AA core. The part also provides a low battery warning circuit.
