The ITE IT8728F is a Super I/O controller commonly used on desktop motherboards, integrating multiple legacy and monitoring functions into a single chip. It supports hardware monitoring, including system voltages, fan speeds, and temperature sensors, enabling system stability and thermal control. The IT8728F also provides traditional I/O functions such as serial ports, parallel ports, and keyboard/mouse interfaces. With LPC (Low Pin Count) bus connectivity, it reduces motherboard complexity while maintaining compatibility with essential PC hardware management features.
