General Description

The IT8712F is a Low Pin Count Interface-based highly integrated Super I/O. The IT8712F provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, such as H/W Monitor, Fan Speed Controller, ITE’s “SmartGuardian” function and Smart Card Reader Interface. The device’s LPC interface complies with Intel “LPC Interface Specification Rev. 1.0”. The IT8712F is ACPI & LANDesk compliant.
