The PC8374L Advanced I/O product is a member of the PC873x SuperI/O family.
All PC873x devices are highly integrated and are pin- and software-compatible, thus providing drop-in interchangeability and enabling a variety of assembly options using only a single motherboard and BIOS.
PC8374L integration allows for a smaller system board size and saves on total system cost.
The PC8374L includes legacy SuperI/O functions, system glue functions, health monitoring and control, commonly used functions such as GPIO, and ACPI-compliant Power Management support.
The PC8374L 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 PC8374L device through an LPC Bus Interface.
The PC8374L 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.
The PC8374L supports both I/O and memory mapping of module registers and enables building legacy-free systems.
