Description and Introduction

128-Pin LPC SuperI/O with MIDI and Game Ports, Extended Wake-Up and Protection The **PC87363-IBW/VLA** from National Semiconductor is a highly integrated **Super I/O controller** designed to manage multiple peripheral interfaces in embedded and computing systems. This component combines essential functions such as **floppy disk control, parallel and serial port management, and keyboard/mouse interfacing**, making it a versatile solution for system designers.  

Built with reliability and efficiency in mind, the PC87363-IBW/VLA supports **LPC (Low Pin Count) bus architecture**, ensuring seamless communication with host processors while minimizing power consumption. Its **programmable features** allow customization for various applications, including industrial automation, point-of-sale systems, and legacy computing platforms.  

Key features include **dual UARTs for serial communication, a flexible parallel port with multiple modes (SPP, EPP, ECP), and integrated floppy disk controller support**. Additionally, it provides **PS/2 keyboard and mouse interfaces**, reducing the need for external components.  

The PC87363-IBW/VLA is housed in a **128-pin PQFP package**, offering robust thermal and electrical performance. Its compatibility with industry standards and low-power operation makes it a preferred choice for legacy and modern embedded systems requiring reliable I/O management.  

Engineers value this component for its **integration, flexibility, and cost-effectiveness**, making it a practical solution for diverse system designs.
