Advanced Super I/O for Desktop

Nuvoton's family of highly integrated WPCD37xx Super I/O devices are pin- and software-compatible, thus providing drop-in interchangeability and enabling a variety of assembly options using only a single motherboard and BIOS. WPCD37xx integration allows for a smaller system board size and saves on total system cost. The WPCD37xx family includes legacy Super I/O functions, system glue functions, commonly used functions such as GPIO, and ACPI-compliant Power Management support. The WPCD37xx family integrates miscellaneous analog and digital system glue functions to reduce the number of discrete components required. The host communicates with the functions integrated in the WPCD37xx devices through an LPC Bus Interface.

Extended wake-up support complements the ACPI controller in the chipset. The System Wake-Up Control (SWC) module, powered by VSB3, supports a flexible wakeup mechanism.
