The IT8705F is a LPC Interface based highly integrated Super I/O. The IT8705F provides the most commonly used legacy Super I/O functionality plus the latest Environment Control initiatives, such as Hardware Monitor, Fan Speed Controller and ITE's "SmartGuardian" function. The device's LPC interface complies with Intel "LPC Interface Specification Rev. 1.0" (Sept. 29, 1997). The IT8705F meets the "Microsoft PC98 & PC99 System Design Guide" requirements and is ACPI compliant.
The IT8705F features the enhanced hardware monitor providing 3 thermal inputs from remote thermistors, thermal diode or diode-connected transistor (2N3904). The device also provides the ITE innovative intelligent automatic Fan ON/OFF & speed control functions (SmartGuardian) to reduce overall system noise and power consumption. It also features a PC/SC and ISO 7816 compliant Smart Card Reader.
The IT8705F has integrated nine logical devices, featuring an Environment Controller (controls three Fans). The Environment Controller has temperature, voltage and Fan Speed monitors. One Fan Speed Controller is responsible to control three fan speeds through three 128 steps of Pulse Width Modulation (PWM) output pins and to monitor three fans' tachometer inputs.
Other features include one high-performance 2.88MB floppy disk controller, with digital data separator, supporting two 360K/ 720K/ 1.2M/ 1.44M/ 2.88M floppy disk drives. One multi-mode high-performance parallel port features the bi-directional Standard Parallel Port (SPP), the Enhanced Parallel Port (EPP V. 1.7 and EPP V. 1.9 are supported), and the IEEE 1284 compliant Extended Capabilities Port (ECP). Two 16C550 standard compatible enhanced UARTs perform asynchronous communication, and support SIR and one consumer remote control (TV remote) IR, one MPU-401 UART mode compatible MIDI port, one game port with built-in 558 quad timers and buffer chips to support direct connection of 2 joysticks, and six ports (44 GPIO pins). There is also a flash ROM interface with Address (FA[0:19]), Data (FD[0:7]), and supporting three control signals FCS#, FWE# and FRD#. In addition, a SmartGuardian engine is provided to monitor the system condition and reacts to the detected condition accordingly.
These nine logical devices can be individually enabled or disabled via software configuration registers. The IT8705F utilizes power-efficient circuitry to reduce power consumption. Once a logical device is disabled, the inputs are gated inhibit, the outputs are TRI-STATE and the input clock is disabled. The IT8705F requires a single 48/24 MHz clock input and operates with a single +5V power supply.
The IT8705F is available in 128-pin PQFP (Plastic Quad Flat Package).
