6 / 109 page  July, 2007 V0.26P 4 F71806 1 General Description The F71806 is the featured IO chip without KBC function specifically for clone chipset PC system. Equipped with one IEEE 1284 parallel port , two UART port and FDC. The F71806 provides SIR, integrated with hardware monitor, supports 11 sets of voltage sensor and 4 voltage fault signal outputs, 3 sets of creative auto-controlling fans and 3 temperature sensor pins for the accurate current type temp. Measurement for CPU thermal diode or external transistors 2N3906. The F71806 provides flexible features for multi-directional application. For instance, supports 12 pins CPU VID controlling for VRM9.0/10.0 and CPU VID OTF (On The Fly), provides 24 GPIO pins which include pulse/level mode selection, IRQ sharing function also designed in UART feature for particular usage and accurate current mode H/W monitor will be worth in measurement of temperature, provides 3 modes fan speed control mechanism included Manual Mode/Speed Mode/Temperature Mode for users’ selection. The F71806 is powered by 3.3V voltage, with the LPC interface in the package of 128-QFP. 2 Features General Functions Comply with LPC Spec. 1.0 Support DPM (Device Power Management), ACPI Support 12 pins CPU VID controlling and comply with VRM9.0/10.0 Vcore monitoring supports dynamic VID 24 GPIO Pins for flexible application 24/48 MHz clock input FDC Compatible with IBM PC AT disk drive systems Variable write pre-compensation with track selectable capability Support vertical recording format DMA enable logic 16-byte data FIFOs Support floppy disk drives and tape drives Detects all overrun and under run conditions Built-in address mark detection circuit to simplify the read electronics Completely compatible with industry standard 82077 360K/720K/1.2M/1.44M/2.88M format; 250K, 300K, 500K, 1M, 2M bps data transfer rate |
