Winbond at 2005, which already had a competing super I/O controller business. In 2008, Winbond then spun off its logic businesses to a wholly owned subsidiary, Nuvoton. SMSC made super I/O chips and then got acquired by Microchip

By combining many functions in a single chip, the number of parts needed on a motherboard is reduced, thus reducing the cost of production.
