Description and Introduction

PC87311A/PC87312 (SuperI/OTM II/III) Floppy Disk Controller with Dual UARTs/ Parallel Port/ and IDE Interface **Introduction to the PC87311AVF Super I/O Controller**  

The PC87311AVF, developed by National Semiconductor, is a highly integrated Super I/O controller designed for embedded and PC-compatible systems. This component combines multiple legacy I/O functions into a single chip, streamlining system design while reducing board space and power consumption.  

Key features of the PC87311AVF include support for floppy disk controllers, parallel ports, serial ports (UARTs), and an infrared (IR) interface. It also integrates a keyboard controller (KBC) and real-time clock (RTC) functionality, making it a versatile solution for industrial, commercial, and consumer applications.  

Built with reliability in mind, the PC87311AVF operates over a wide voltage range and is compatible with industry-standard interfaces. Its low-power design makes it suitable for energy-efficient systems, while its robust architecture ensures stable performance in demanding environments.  

The device is commonly used in legacy PC motherboards, point-of-sale terminals, and embedded control systems where backward compatibility with traditional peripherals is essential. With its comprehensive feature set and proven reliability, the PC87311AVF remains a practical choice for designers seeking a cost-effective Super I/O solution.
