Description and Introduction

CMOS Priority Interrupt Controller The **82C59A-12** is a programmable interrupt controller (PIC) manufactured by **HAR (Harris Semiconductor)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Harris Semiconductor (HAR)  
- **Part Number:** 82C59A-12  
- **Type:** CMOS Programmable Interrupt Controller  
- **Speed Grade:** -12 (12 MHz operation)  
- **Package:** 28-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Operating Voltage:** 5V  
- **Technology:** CMOS  

### **Descriptions:**
- The **82C59A-12** is an enhanced version of the Intel 8259A PIC, designed for managing hardware interrupts in microprocessor-based systems.  
- It supports **8 priority levels** of interrupts and can be cascaded to handle up to **64 interrupts** using multiple chips.  
- It is widely used in **x86-based systems** (e.g., IBM PC/AT compatibles) for interrupt handling.  

### **Features:**
- **Fully Programmable:** Interrupt modes and priorities can be configured via software.  
- **Cascadable:** Supports master-slave configurations for expanding interrupt handling.  
- **Edge and Level Triggered Modes:** Can be configured for edge-sensitive or level-sensitive interrupts.  
- **Automatic EOI (End of Interrupt):** Supports both manual and automatic interrupt acknowledgment.  
- **Compatibility:** Fully compatible with Intel 8259A and other industry-standard PICs.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  

This information is based solely on the factual details of the **82C59A-12** from Harris Semiconductor.
