Description and Introduction

CMOS Programmable Peripheral Interface The **82C55A** is a CMOS Programmable Peripheral Interface (PPI) manufactured by **Intersil**. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Intersil  
- **Type:** CMOS Programmable Peripheral Interface (PPI)  
- **Operating Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** Commercial (0°C to +70°C) and Industrial (-40°C to +85°C)  
- **Package Options:** 40-pin DIP (Dual In-line Package) and 44-pin PLCC (Plastic Leaded Chip Carrier)  
- **Technology:** High-speed CMOS  
- **Power Consumption:** Low power consumption due to CMOS technology  

### **Descriptions:**  
- The **82C55A** is a general-purpose programmable I/O device designed for use with microprocessors.  
- It provides **three 8-bit ports (Port A, Port B, Port C)** that can be independently configured for input or output operations.  
- Port C can also be split into two 4-bit ports for bit-wise control.  
- It supports multiple operating modes, including **Mode 0 (Basic Input/Output), Mode 1 (Strobed Input/Output), and Mode 2 (Bidirectional Bus).**  

### **Features:**  
- **Three 8-bit I/O ports** (24 I/O lines total).  
- **Fully TTL-compatible** for easy interfacing with TTL logic.  
- **Bit Set/Reset capability** for individual port bits.  
- **Programmable modes** for flexible I/O configurations.  
- **Low standby power consumption** (typical CMOS power-saving features).  
- **Compatible with Intel 8080, 8085, 8086, and other microprocessors.**  
- **Direct bit manipulation** for control applications.  

This information is based on the manufacturer's datasheet and technical documentation.
