Description and Introduction

8K x 8 BIT CMOS ELECTRICALLY ERASABLE PROM The **KM28C65A** is a 64K x 8-bit CMOS EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **Samsung**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 64K x 8-bit (65,536 bytes)  
- **Technology:** CMOS EEPROM  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 150 ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Package Type:** 28-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Write Cycle Time:** 10 ms (maximum)  
- **Data Retention:** 10 years minimum  
- **Endurance:** 10,000 write/erase cycles per byte  

### **Descriptions:**
- The **KM28C65A** is a byte-erasable EEPROM, allowing individual byte modification without requiring a full chip erase.  
- It supports both **read** and **write** operations with standard microprocessor interfaces.  
- Features a **page write mode** for faster programming (up to 64 bytes per page).  
- Includes **automatic erase-before-write** functionality, simplifying software control.  

### **Features:**
- **Low Power Consumption:**  
  - Active current: 30 mA (typical)  
  - Standby current: 100 µA (typical)  
- **Hardware & Software Data Protection:**  
  - Prevents accidental writes via VCC detection and write-lock circuitry.  
- **TTL-Compatible Inputs & Outputs:**  
  - Ensures compatibility with standard logic levels.  
- **Self-Timed Write Cycle:**  
  - Eliminates the need for external timing components.  
- **Industry-Standard Pinout:**  
  - Compatible with other 28-pin EEPROMs like the **28C64**.  

This EEPROM is commonly used in embedded systems, industrial controls, and consumer electronics requiring non-volatile memory storage.
