Desktop and Super I/O

System Management Simplified

Super I/O chips combine the functionality of many low-bandwidth device controllers into a single product. Our super I/O devices have additional integrated features for total system management.

Full Legacy I/O Management

Serial ports
Parallel ports
Flexible GPIOs
Floppy disk companion
Keyboard/mouse

Microchip Advantages

Best-in-class product lifecycles
Most accurate system monitoring in an I/O controller
~70% smaller footprint compared to similar three-chip solution
Industrial-grade operating range

Applications

Desktops and all-in-ones
Industrial PCs
Set-top boxes
Kiosks and Automated Teller Machines (ATMs)
Point-of-Sale (POS) terminals

Our portfolio of Super I/O controllers offer solutions for all types of embedded solutions. We offer simplified I/Os to fit your budget while delivering long-lasting performance. We also offer feature-rich Super I/Os, like the SCH3227, which incorporate flexible I/O control and accurate system monitoring in miniscule packages. This integration eliminates the need for other chips, saving space and reducing operating expenses.
