Product Summary

The IT8718F-S is a Low Pin Count Interface-based highly integrated Super I/O. The IT8718F-S provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives. The IT8718F-S LPC interface complies with Intel LPC Interface Specification Rev. 1.0. The IT8718F is ACPI & LANDesk compliant. The IT8718F-S features the enhanced hardware monitor providing 3 thermal inputs from remote thermal resistors, or thermal diode or diode-connected transistor (2N3904). The IT8718F-S also provides the ITE innovative intelligent automatic Fan ON/OFF & speed control functions (SmartGuardian) to protect the system, reducing the system noise and power consumption.
