Winbond W83782D (sensor)

Added by ALMICO on 09 nov 2000


Description: 
W83782D is an evolving version of W83781D, Winbond's most popular hardware status monitoring IC. The W83782D 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. W83782D provides both ISA and I2C serial bus interface. An 8-bit analog-to-digital converter (ADC) was built inside W83782D. The W83782D can simultaneously monitor 9 analog voltage inputs, 2 fan tachometer inputs, 3 remote temperature, one case-open detection signal. The remote temperature sensing can be performed by thermistors, or 2N3904 NPN-type transistors, or directly from IntelTM Deschutes CPU thermal diode output. Also the W83782D provides: 4 PWM (pulse width modulation) outputs for the fan speed control; beep tone output for warning; SMI#, OVT#, GPO# 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. 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 is out of the preset range. Additionally, 5 VID inputs are provided to read the VID of CPU (i.e. Pentium II) if applicable. This is to provide the Vcore voltage correction automatically. Also W83782D uniquely provides an optional feature: early stage (before BIOS was loaded) beep warning. This is to detect if the fatal elements present (Vcore or +3.3V) fail, and the system can not be booted up. Also there are 3 specific pins to provide selectable address setting for application of multiple devices (up to 8 devices) wired through I2C interface.

Hm, only second FCPGA needed :)
