W83697HF arduino
W83697HF
The W83697HF provides Flash ROM interface. That can support up to 4M legacy flash ROM.
The W83697HF support hardware status monitoring for personal computers. It 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 stably and properly.
Moreover, W83697HF support the Smart Fan control system, including the “Thermal CruiseTM” and “Speed
CruiseTM” functions. Smart Fan can make system more stable and user friendly.
