General Description
The IT8702F is a Low Pin Count Interface-based highly integrated Super I/O. The IT8702F provides the most commonly used legacy Super I/O functionality plus the Fan Speed Controller and Smart Card Reader Interface. The device’s LPC interface complies with Intel “LPC Interface Specification Rev. 1.0”. The IT8702F is ACPI & LANDesk compliant.
The IT8702F features a PC/SC and ISO 7816 compliant Smart Card Reader. The IT8702F 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.Features
