7. HARDWARE MONITOR
7.1
The W83627UHG monitors several critical parameters in PC hardware, including power supply voltages, fan
speeds, and temperatures, all of which are very important for a high-end computer system to work stably and
properly. In addition, proprietary hardware reduces the amount of programming and processor intervention to
control cooling fan speeds, minimizing ambient noise and maximizing system temperature and reliability.
The W83627UHG can simultaneously monitor all of the following inputs:
These inputs are converted to digital values using the integrated, eight-bit analog-to-digital converter (ADC).
In response to these inputs, the W83627UHG can generate the following outputs:
The W83627UHG provides hardware access to all monitored parameters through the LPC or I
software access through application software, such as Nuvoton’s Hardware Doctor
W83627UHG can generate pop-up warnings or beep tones when a parameter goes outside of a user-specified
range.
The rest of this section introduces the various features of the W83627UHG hardware-monitor capability. These
