WPCD374L integration allows for a smaller system board size and saves on total system cost. The WPCD374L includes legacy Super I/O functions, system glue functions, health monitoring and control, commonly used functions such as GPIO, and ACPI-compliant Power Management support. The WPCD374L 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 WPCD374L device through an LPC Bus Interface. The WPCD374L extended wake-up support complements the ACPI controller in the chipset. The System Wake-Up Control (SWC) module, powered by VSB3, supports a flexible wake-up mechanism. The WPCD374L supports both I/O and memory mapping of module registers and enables building legacy-free systems.
