7 / 97 page  W83792AD/AG/D/G Publication Release Date: April 26, 2006 - 1 - Revision 0.9 1. GENERAL DESCRIPTION W83792AD/AG and W8392D/G are two parts support single and dual CPU application, the former is for single CPU application which provides 1 set thermal trip and 1 set of VID controlling; the latter is for dual CPU application which provides dual CPU VID controlling and 2 sets of thermal trip. Other functions are all the same without difference except thermal trip and VID controlling numbers. W83792D/G is an evolving version of the W83791D --- Winbond's most popular hardware status monitoring IC. Besides the conventional functions of W83791D, W83792D/G uniquely provides several innovative features such as support dual CPU VID controlling, VRM9.0 and VRD10.0 specifications supported, ASF 2.0 specification compliant, SMBus 2.0 ARP command compatible, 2 sets of Thermal trip, 12 VID control, 6 sets of Smart fan TM, VID table selection trapping. Conventionally, W83792D/G 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, such as server, workstation…etc, working very stably and efficiently. A 10-bit analog-to-digital converter (ADC) was built inside W83792D/G. W83792D/G can simultaneously monitor 9 analog voltage inputs (including power VDD/5VSB monitoring), 6 fan tachometer inputs, 3 remote temperatures, and Watch Dog Timer function. The sense of remote temperature can be performed by thermistors, or directly from Intel TM CPU with thermal diode output. W83792D/G provides 6 PWM (pulse width modulation)/DC fan output modes for smart fan control - Thermal Cruise TM mode and Smart Fan TM II mode. Under Thermal Cruise TM mode, temperatures of CPU and the system can be maintained within specific programmable ranges under the hardware control. As Smart Fan TM II, which provides 4 sets of temperatures point each could control fan’s duty cycle, depends on this construction, fan could be operated at the lowest possible speed so that the acoustic noise could be avoided. As for warning mechanism, W83792D/G provides SMI#, OVT#, IRQ signals for system protection events. Additionally, 12 VID inputs are provided to read 2 sets of VID for CPU (i.e. Pentium TM III/4). These VID inputs provide the information of Vcore voltage that CPU expects. W83792D/G also has 2 specific pins to provide selectable address setting for application of multiple devices (up to 4 devices) wired through I 2C interface. W83792D/G can uniquely serve as an ASF sensor to respond to ASF master’s request for the implementation of network management in OS-absent status. Through W83792D/G’s compliance with ASF2.0 sensor specification, network server is able to monitor the environmental status of each client in OS-absent state by PET (Platform Event Trip) frame values returned from W83792D/G, such as temperatures, voltages, fan speed, thermal trip, and case open. Moreover, W83792D/G supports SMBus 2.0 ARP command to solve the problem of address conflicts by dynamically assigning a new unique address for W83792D/G ASF Function after W83792D/G’s UDID is sent. Through the application software or BIOS, the users can read all the monitored parameters of the system from time to time. A pop-up warning can also be activated when the monitored item is out of the proper/preset range. The application software could be Winbond's Hardware DoctorTM, IntelTM LDCM (LanDesk Client Management), or other management application software. Besides, the users can set up the upper and lower limits (alarm thresholds) of these monitored parameters and activate one programmable and maskable interrupts. |
