The W83627UHG is a super I/O chip with an LPC interface produced by Winbond, mainly used in x86 – architecture computer systems to provide rich I/O functions. Here is a detailed introduction to its functions:
– Integrated I/O Controller: It integrates various I/O controllers, including serial ports, keyboard/mouse controllers, parallel ports, etc., meeting the basic I/O needs of computer systems.
– Hardware Monitoring: The chip can monitor system hardware, such as temperature, voltage, and fan speed. It supports high – precision temperature sensors like thermal diodes and thermistors, and can also control fan speed through SMART FAN™ technology to achieve the best balance between fan noise and heat dissipation. In addition, it monitors the voltage of computer hardware to ensure the normal operation of the computer in harsh environments.
– Power Management: The W83627UHG has enhanced power management capabilities and can more precisely control the power status of the system. For example, it supports more energy – efficient management in the S5 state.
– Additional Functions: This chip also provides an 8 – bit digital – to – analog converter, two 5 – bit digital – to – analog converters, four system status indicators, and eight power management control bits. These functions can be used to maintain appropriate temperatures, voltages, and fan speeds, and can also be used for system monitoring, testing, and diagnostics.
