PC8374T Datasheet | National Semiconductor

Description The National Semiconductor PC8374T Advanced I/O product is a member of the PC837x Super I/O family. All PC837x devices are highly integrated and are pin and software patible, 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 Super I/O functions, Trusted Platform Module (TPM), system glue functions, health monitoring and control, monly used functions such as GPIO, and ACPI-pliant Power Management support. The Trusted Platform Module provides a solution for PC security, based on the TCG standard. The plete security solution includes hardware, software, and firmware. The PC8374T integrates miscellaneous analog and digital system glue functions to reduce the number of discrete ponents required. The host municates 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.
