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. The IT8712F features the enhanced hardware monitor providing 3 thermal inputs from remote thermal resistors, or thermal diode or diode-connected transistor (2N3094). 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. It also features a PC/SC and ISO 7816 compliant Smart Card Reader. The IT8712F contains one game port which supports 2 joysticks, 1 MIDI port, and 1 Fan Speed Controller. The fan speed controller is responsible to control 5 fan speeds through three 128 steps of Pulse Width Modulation (PWM) output pins and to monitor five FANs’ Tachometer inputs. It also features two 16C550 UARTs, one IEEE 1284 Parallel Port, one Floppy Disk Controller and one 8042 Keyboard Controller.
