Description and Introduction

PC98 and ACPI Compliant SuperI/O with System Wake-up Control The **PC87351IBW/VLA** from National Semiconductor is a versatile **Super I/O controller** designed to manage a variety of input/output functions in embedded systems and desktop computing applications. This integrated circuit combines multiple peripheral interfaces into a single chip, enhancing system efficiency while reducing component count.  

Key features of the PC87351IBW/VLA include support for **floppy disk controllers, parallel ports, serial ports (UARTs), and keyboard/mouse interfaces**. Its flexible architecture allows seamless integration with legacy and modern systems, making it suitable for industrial, commercial, and consumer electronics.  

Built with **low-power CMOS technology**, the device ensures reliable performance while minimizing energy consumption. It also incorporates **programmable power management**, enabling optimized operation in power-sensitive environments. The chip is housed in a **PLCC (Plastic Leaded Chip Carrier) package**, ensuring robust physical connectivity and ease of assembly.  

With its comprehensive I/O capabilities and dependable design, the PC87351IBW/VLA remains a practical solution for system designers seeking a consolidated interface controller. Its compatibility with industry standards ensures broad applicability across diverse computing and embedded platforms.  

For detailed specifications, refer to the official datasheet to ensure proper implementation in target systems.

Application Scenarios & Design Considerations

PC98 and ACPI Compliant SuperI/O with System Wake-up Control

Alternative Part Number

  • FDC37C669 --: Super I/O controller with comparable floppy, serial, parallel and keyboard functions, widely used as a drop-in replacement for legacy National Super I/O parts.
  • W83627HF --: Popular LPC Super I/O chip offering similar legacy I/O integration and often used to replace older National PC873xx devices in embedded designs.
  • IT8712F --: LPC Super I/O controller with comparable feature set for legacy motherboard and embedded applications, serving as a functional substitute.
  • W83L951DG --: Pin-compatible Super I/O controller with similar LPC interface and legacy I/O feature set, commonly used as a drop-in replacement for the PC87351 family.
  • FDC37N972 --: Super I/O device offering comparable LPC-based legacy I/O functions and a similar integration level, suitable for designs originally using the PC87351.
  • IT8728F --: Widely available Super I/O controller with LPC interface and comparable legacy I/O blocks; requires minor configuration changes but is a practical functional alternative.
