Description and Introduction

CMOS Priority Interrupt Controller The **IP82C59A-5** is a **Programmable Interrupt Controller (PIC)** manufactured by **Harris Semiconductor**. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Harris Semiconductor  
- **Part Number:** IP82C59A-5  
- **Type:** CMOS Programmable Interrupt Controller  
- **Operating Voltage:** 5V  
- **Speed Grade:** -5 (5 MHz operation)  
- **Package:** 28-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Technology:** CMOS  
- **Compatibility:** Fully compatible with Intel’s 8259A  

### **Descriptions:**
- The **IP82C59A-5** is a high-performance, low-power CMOS version of the industry-standard 8259A Programmable Interrupt Controller.  
- It manages up to **8 interrupt request (IRQ) inputs** and can be cascaded to handle **64 interrupts** in a master-slave configuration.  
- It is designed for use in microprocessor-based systems to prioritize and manage interrupt requests efficiently.  

### **Features:**
- **8-Level Priority Interrupt Control**  
- **Expandable to 64 Levels via Cascading**  
- **Programmable Interrupt Modes:**  
  - Fully Nested Mode  
  - Rotating Priority Mode  
  - Polled Mode  
- **Individual Interrupt Masking**  
- **Edge and Level Triggered Interrupt Inputs**  
- **Compatible with 8085, 8086, 8088, and other x86 Microprocessors**  
- **Low Power Consumption (CMOS Technology)**  
- **5V Single Supply Operation**  
- **28-Pin DIP or PLCC Packaging Options**  

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

Application Scenarios & Design Considerations

CMOS Priority Interrupt Controller

Alternative Part Number

  • 8259A-5 --: Original Intel programmable interrupt controller in the same 5 MHz speed grade, pin and function compatible with the Harris IP82C59A-5.
  • W82C59A-5 --: CMOS 8259A-compatible interrupt controller rated at 5 MHz, a direct functional replacement for the Harris part.
  • M82C59A-5 --: CMOS 8259A-compatible PIC with 5 MHz operation, offering equivalent functionality and pinout as an alternative source.
