SCH5627P-NS

The SCH5627 is a 3.3V PC 2001 compliant SuperI/O controller with an LPC interface. All legacy drivers used for SuperI/O components are supported, making this interface transparent to thesupporting software. The LPC bus also supports power management, such aswake-up and sleep modes.

This device can monitor up to three external diodes, oneinternal ambient temperature sensor or retrieving temperatures fromexternal processors that
implement the PECI (Platform EnvironmentalControl Interface).

The Glue Logic includes various power management logic,including generation of RSMRST# and Power OK signal generation. The partalso provides a low battery warning circuit, as well as 60 General PurposeI/O control pins, which offer flexibility to the system designer. A high-performance embeddedmicrocontroller incorporated and communication-capable with the system hostusing the Intel® Low Pin Count bus.
