Description
AI
The SCH5627 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 can monitor up to three external diodes, one
internal ambient temperature sensor or retrieving temperatures from
external processors that
implement the PECI (Platform Environmental
Control Interface).
The Glue Logic includes various power management logic,
including generation of RSMRST# and Power OK signal generation. The part
also provides a low battery warning circuit, as well as 60 General Purpose
I/O control pins, which offer flexibility to the system designer. A high-performance embedded
microcontroller incorporated and communication-capable with the system host
using the Intel® Low Pin Count bus.
