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.
