Winbond Lpc I/o

  The W83627THF can be used to monitor several critical hardware parameters of the system, including power supply voltages, fan speeds, and temperatures, which are very important for a high-end computer system to work stable and properly. W83627THF provides LPC Interface to access hardware . An 8-bit analog-to-digital converter (ADC) was built inside W83627THF. The W83627THF can simultaneously monitor 3 analog voltage inputs (addition monitor VBAT, 5VSB & 5VCC power), 3 fan tachometer inputs, 3 remote temperature inputs and one case-open detection signal. The remote temperature sensing can be performed by thermistors, 2N3904 NPN-type Transistors or directly from IntelTM CPU thermal Diode output. Also the W83627THF provides: 3 analog outputs for fan speed control. Beep Tone output for warning; SMI#(can through SERIRQ pin), OVT# signals for system protection events. Through the application software or BIOS, the users can read all the monitored parameters of system from time to time. And a pop-up warning can be also activated when the monitored item was out of the proper/preset range. The application software could be Winbond's Hardware DoctorTM, or IntelTM LDCM (LanDesk Client Management), or other management application software. Also the users can set up the upper and lower limits (alarm thresholds) of these monitored parameters and to activate one programmable and maskable interrupts. An optional beep Tone could be used as warning signal when the monitored parameters are out of the preset range.W83627THG's datasheet is the same as W83627THG
