GENERAL DESCRIPTION
W83L785R is a condensed product of W83L785R --- Winbond's most popular hardware monitoring IC for notebook. Specifically designed for the graphic cards and notebook systems, W83L785R can be used to monitor several critical hardware parameters of the system, including voltages, fan speeds, and temperatures, which are very important for the system to work stably and properly. An 8-bit analog-to-digital converter (ADC) was built inside W83L785R. The W83L785R provides 2 PWM (pulse width modulation) outputs for the fan speed control. Also the W83L785R provides: SMI#, OVT#, Temp fault, GPIO signals for system protection events; I2CTM serial bus interface. W83L785R also provides 4 pure GPIO and 7 multifunctional GPIO pins, and powered by 3.3V. 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.
