The Fintek F8000 is a legacy Super I/O controller chip used on desktop motherboards to manage low-bandwidth system functions. Produced by Fintek, it integrates hardware monitoring, fan speed control, temperature sensing, and voltage detection. The chip also provides interfaces for serial ports, parallel ports, floppy controllers, and PS/2 devices. Connected via the LPC (Low Pin Count) bus, the F8000 helped system builders reduce component count while maintaining essential motherboard management and environmental monitoring features for stable PC operation.
