The IT8728F is a highly integrated Super I/O using the LowPin Count Interface. It provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, including H/W Monitor and Fan Speed Controller. The device’s LPC interface complies with Intel “LPC Interface Specification Rev. 1.1”. The IT8728F is ACPI & LANDesk compliant.
The IT8728F features an enhanced hardware monitor providing three thermal inputs from remote thermal resistors, or thermal diode or diode-connected transistor (2N3904/2N3906). The device employs ITE’s innovative intelligent automatic Fan ON/OFF & speed control functions (SmartGuardian)to protect the system while reducing the system noise and power consumption.The Fan Speed Controller can control up to five fan speeds through five separate 256 steps of Pulse Width Modulation (PWM) output pins and monitor up to five FANs’ Tachometer inputs.
