General Description

IT8716F is a Low Pin Count Interface-based highly integrated Super I/O. The IT8716F 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 IT8716F is ACPI & LANDesk compliant. The IT8716F support Serial Flash I/F for BIOS firmware.

The  IT8716F 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. It also features a PC/SC and ISO 7816 compliant Smart Card Reader.

The IT8716F is available in 128-pin QFP (Quad Flat Package).
