Description and Introduction

CMOS Static Clock Controller/Generator The **Intersil 82C85** is a CMOS version of the **Intel 82C85** Peripheral Controller, designed for use in microprocessor-based systems. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Intersil  
- **Technology:** CMOS  
- **Function:** Programmable Peripheral Interface (PPI)  
- **Compatibility:** Pin-compatible with NMOS 82C85  
- **Operating Voltage:** Typically **5V**  
- **Power Consumption:** Low power due to CMOS technology  
- **Package Type:** Likely **DIP (Dual In-line Package)** or other standard IC packaging  

### **Descriptions:**
- The **82C85** is a **programmable I/O controller** used to interface peripheral devices with microprocessors.  
- It provides **three 8-bit I/O ports** (Port A, Port B, Port C) that can be configured for input or output operations.  
- Supports **handshaking and interrupt-driven data transfer** for efficient communication.  
- Used in systems requiring **parallel I/O expansion**, such as industrial control, instrumentation, and embedded applications.  

### **Features:**
1. **Three Programmable 8-bit Ports** (Port A, B, C)  
2. **Bit Set/Reset Capability** (for Port C)  
3. **Modes of Operation:**  
   - **Mode 0 (Basic Input/Output)**  
   - **Mode 1 (Strobed Input/Output)**  
   - **Mode 2 (Bidirectional Bus)**  
4. **CMOS Technology Advantages:**  
   - Lower power consumption  
   - Higher noise immunity  
   - Wider operating temperature range  
5. **Compatible with Intel 8080/8085, Z80, and other microprocessors**  
6. **TTL-Compatible Inputs/Outputs**  

This information is based on the general specifications of the **Intersil 82C85** as a CMOS variant of the Intel 82C85 peripheral controller. For exact datasheet details, refer to official Intersil documentation.
