1 / 239 page  www.national.com Preliminary May 2004 Revision 1.1 PC8374L SensorPathTM SuperI/O with Glue Functions General Description The National Semiconductor PC8374L Advanced I/O prod- uct is a member of the PC837x SuperI/O family. All PC837x devices are highly integrated and are pin and software com- patible, 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 wake- up mechanism. The PC8374L supports both I/O and memory mapping of module registers and enables building legacy-free systems. Outstanding Features ■ SensorPath interface to LMxx sensor devices for system health support ■ Fan monitor and control ■ Heceta6-compatible register set, accessible via the LPC interface and SMBus ■ Glue functions to complement the South Bridge func- tionality ■ VSB3-powered Power Management with 19 wake-up sources ■ Controls three LED indicators ■ 16 GPIO ports with a variety of wake-up options ■ I/O-mapped and memory-mapped registers ■ Legacy modules: Parallel Port, Floppy Disk Controller (FDC), two Serial Ports, Slow InfraRed Port and a Key- board and Mouse Controller (KBC) ■ LPC interface, based on Intel’s LPC Interface Specifica- tion Revision 1.1, August 2002 ■ PC01 Revision 1.0 and Advanced Configuration and Power Interface (ACPI) Specification Revision 2.0 compliant ■ 128-pin PQFP package Block Diagram LMxx Sensors SensorPathTM I/F Drv Drv LPC Bus South Bridge Serial Interfaces Parallel Port Interfaces Floppy Drive Interface PS/2 Interfaces KBC Ports Infrared Interface GPIO Ports PC8374L Drv Tacho PWM LEDs Power Supply Reset Logic Power Management VBAT SMBus I/F System BIOS National Semiconductor and TRI-STATE are registered trademarks of National Semiconductor Corporation.
