Controller IC Chip - IT8720F HXS IT8720F-HXS chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0562)
The IT8720F is a highly integrated Super I/O using the Low Pin Count Interface. The IT8720F 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. 1.0â€. The IT8720F is ACPI & LANDesk compliant. The IT8720F features the enhanced hardware monitor providing 3 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 IT8720F contains one Fan Speed Controller. The fan speed controller can control up to five fan speeds through three separate 128 steps of Pulse Width Modulation (PWM) output pins and monitor up to five FANs’ Tachometer inputs. It also features two 16C550 UARTs, one IEEE 1284 Parallel Port, one Floppy Disk Controller and one Keyboard Controller. Integrated in the IT8720F are eight logical devices. One high-performance 2.88MB floppy disk controller, with digital data separator, supporting two drives in 360K/720K/1.2M/1.44M/2.88M format. One multi-mode high-performance parallel port supporting bi-directional Standard Parallel Port (SPP), Enhanced Parallel Port (EPP V. 1.7 and EPP V. 1.9), and IEEE 1284 compliant Extended Capabilities Port (ECP). Two 16C550 standard compatible enhanced UARTs perform asynchronous communication, and also support IR interface. The device also features one fan speed controller which controls and monitors five fans, and eight GPIO ports controlling up to 63 GPIO pins. The IT8720F also has an integrated Keyboard Controller. These eight logical devices can be individually enabled or disabled via software configuration registers. The IT8720F utilizes power-saving circuitry to reduce power consumption, and once a logical device is disabled, the inputs are inhibited with the clock disabled and the outputs are tri-stated. The device requires a single 24/48 MHz clock input and operates with +5V power supply. The IT8720F is available in 128-pin QFP (Quad Flat Package)
