Description
The IT8718F-S is a Low Pin Count Interface-based highly integrated Super I/O. The device provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, such as H/W Monitor, Fan Speed Controller. The device’s LPC interface complies with Intel “LPC Interface Specification Rev. 1.0”. The IT8718F is ACPI & LANDesk compliant.
The IT8718F features the enhanced hardware monitor providing 3 thermal inputs from remote thermal
resistors, or thermal diode or diode-connected transistor (2N3904). The device 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.

(4) 1 chassis open detection input with low power Flip-Flop backed by the battery
(5) Watch Dog comparison of all monitored values
(6) Provides VID0 – VID7 support for the CPU
(7) SST/PECI/AMDSI I/F support.
2. Fan Speed Controller
(1) Provides fan on-off and PWM control
(2) Supports 3 programmable Pulse Width Modulation (PWM) outputs
(3) 128 steps of PWM modes
(4) Monitors 5 fan tachometer inputs
