GENERAL DESCRIPTION\nThe W83627HF and W83627F are evolving product fromWinbond's most popular I/O family. They\nfeature a whole new interface, namely LPC（Low Pin Count）interface, which will be supported in the next generation Intel chip-set. This interface as its name suggests is to provide an economical implementation of I/O's interface with lower pin countand still maintains equivalent performance as its ISA interface counterpart. Approximately 40 pin counts are saved in LPC I/O comparing to ISA implementation. With this additional freedom, we can implement more devices on a single chip as demonstrated in W83627F/HF's integration of Game Port and MIDI Port.It is fully transparentin terms of software which means no BIOS or device driver update is needed except chip-specific configuration.FEATURES\nGeneral\n• Meet LPC Spec. 1.0\n•Support LDRQ#（LPC DMA）, SERIRQ （serial IRQ）\n• Include all the features of Winbond I/O W83977TF and W83977EF\n• Integrate Hardware Monitor functions\n• Compliant with Microsoft PC98/PC99 Hardware Design Guide\n•Support DPM （Device Power Management）, ACPI\n• Programmable configuration settings\n• Single 24 or 48 MHz clock input\n\nFDC\n• Compatible with IBM PC AT disk drive systems\n• Variable write pre-compensation with track selectable capability\n• Support vertical recording format\n• DMA enable logic\n• 16-byte data FIFOs\n• Support floppy disk drives and tape drives\n• Detects all overrun and underrun conditions\n• Built-in address mark detection circuit to simplify the read electronics\n• FDD anti-virus functions with software write protect and FDD write enable signal （write data\nsignal was forced to be inactive）\n• Support up to four 3.5-inch or 5.25-inch floppy disk drives\n• Completely compatible with industry standard 82077\n• 360K/720K/1.2M/1.44M/2.88M format; 250K, 300K, 500K, 1M, 2M bps data transfer rate\n• Support 3-mode FDD, and its Win95/98 driver\n\nUART\n• Two high-speed 16550 compatible UARTs with 16-byte send/receive FIFOs\n•MIDI compatible\n• Fully programmable serial-interface characteristics：\n─5, 6, 7 or 8-bit characters\n─Even, odd or no parity bit generation/detection\n─1, 1.5 or 2 stop bits generation\n• Internal diagnostic capabilities：\n─Loop-back controls for communications link fault isolation\n─Break, parity, overrun, framing error simulation\n• Programmable baud generator allows division of 1.8461 MHz and 24 MHz by 1 to （216-1）\n• Maximum baud rate up to 921k bps for 14.769 MHz and 1.5M bps for 24 MHz\n\nInfrared\n• Support IrDA version 1.0 SIR protocol with maximum baud rate up to 115.2K bps\n\nParallel Port\n• Compatible with IBM parallel port\n• Support PS/2 compatible bi-directional parallel port\n• Support Enhanced Parallel Port（EPP）−Compatible with IEEE 1284 specification\n• Support Extended Capabilities Port（ECP）−Compatible with IEEE 1284 specification\n• Extension FDD mode supports disk drive B; and Extension 2FDD mode supports disk drives A\nand B through parallel port\n• Enhanced printer port back-drive current protection\n\nKeyboard Controller\n• 8042 based with optional F/W from AMIKKEYTM -2,or customer code with 2K bytes of program\nmable ROM, and 256 bytes of RAM\n• Asynchronous Access to Two Data Registers and One status Register\n• Software compatibility with the 8042\n• Support PS/2 mouse\n• Support port 92\n• Support both interrupt and polling modes\n• Fast Gate A20 and Hardware Keyboard Reset\n• 8 Bit Timer/ Counter\n• Support binary and BCD arithmetic\n• 6 MHz, 8 MHz, 12 MHz, or 16 MHz operating frequency\n\nGame Port\n• Support two separate Joysticks\n• Support every Joystick two axis （X,Y）and two button （A,B）controllersMIDI Port\n• The baud rate is 31.25 Kbaud\n• 16-byte input FIFO\n• 16-byte output FIFO\n\nGeneral Purpose I/O Ports\n• 22 programmable general purpose I/O ports\n• General purpose I/O ports can serve as simple I/O ports, interrupt steering inputs, watch dog\ntimer output, power LED output, infrared I/O pins, KBC control I/O pins, suspend LED output,\nRSMRST# signal, PWROK signal, Beep output\n• Functional in power down mode （GP1 only） OnNow Functions\n• Keyboard Wake-Up by programmable keys\n• Mouse Wake-Up by programmable buttons\n• CIR Wake-Up by programmable keys\n• On Now Wake-Up from all of the ACPI sleeping states （S1-S5）\n\nHardware Monitor Functions （Only for W83627HF）\n• 5 VID input pins for CPU Vcore identification\n• 3 thermal inputs from optionally remote thermistors or 2N3904 transistors or PentiumTM II\n（Deschutes）thermal diode output\n• 7 positive voltage inputs （typical for +12V, -12V, +5V, -5V, +3.3V, VcoreA, VcoreB）\n• 2 intrinsic voltage monitoring （typical for Vbat, +5VSB）\n• 3 fan speed monitoring inputs\n• 2 fan speed control\n• Build in Case open detection circuit\n• WATCHDOG comparison of all monitored values\n• Programmable hysteresis and setting points for all monitored items\n• Over temperature indicate output\n• Automatic Power On voltage detection Beep\n• Issue SMI#, IRQ, OVT# to activate system protection\n•Intel LDCMTM / Acer ADMTM compatible\n\nPackage\n• 128-pin PQFP
