Description and Introduction

CMOS Priority Interrupt Controller The IP82C59A is a CMOS Priority Interrupt Controller manufactured by Intersil. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Intersil  
- **Part Number:** IP82C59A  
- **Technology:** CMOS  
- **Operating Voltage:** 5V  
- **Package Type:** 28-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Interrupt Levels:** 8 levels, expandable to 64 levels via cascading  
- **Compatibility:** Fully compatible with Intel 8259A  

### **Descriptions:**
- The IP82C59A is a programmable interrupt controller designed to manage multiple interrupt requests from peripheral devices in microprocessor-based systems.  
- It prioritizes interrupts and provides the processor with the highest-priority interrupt vector.  
- It supports both edge-triggered and level-triggered interrupt modes.  

### **Features:**
- **Fully Programmable:** Allows flexible interrupt handling configurations.  
- **Cascading Capability:** Can be cascaded to support up to 64 interrupt levels.  
- **Automatic EOI (End of Interrupt) Mode:** Simplifies interrupt handling in software.  
- **Buffered Mode Support:** Enables direct connection to system data buses.  
- **Polled or Vectored Interrupt Modes:** Provides flexibility in interrupt handling.  
- **Low Power Consumption:** Due to CMOS technology.  
- **Compatibility:** Pin and function compatible with the Intel 8259A.  

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