The National Semiconductor PC8374T Advanced I/O product is a member of the PC837x SuperI/O family. All PC837x 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. PC8374T integration allows for a reduced system board size and saves on total system cost.
The PC8374T includes legacy SuperI/O functions, Trusted Platform Module (TPM), system glue functions, health monitoring and control, commonly used functions such as GPIO, and ACPI-compliant Power Management support. The Trusted Platform Module provides a solution for PC security, based on the TCG standard. The complete security solution includes hardware, software, and firmware.
The PC8374T 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 PC8374T through an LPC Bus Interface.
The PC8374T supports both I/O and memory mapping of module registers and enables building legacy-free systems.
