Description and Introduction

4 MBIT (256KB X16) UV EPROM AND OTP ROM The **M27C4002-12C1** is an EPROM (Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics (ST)**. Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Memory Size:** 4 Mbit (512K x 8)  
- **Organization:** 512K x 8 bits  
- **Access Time:** 120 ns  
- **Supply Voltage (VCC):** 5V ±10%  
- **Operating Temperature Range:**  
  - Commercial (0°C to +70°C)  
  - Industrial (-40°C to +85°C)  
- **Package Type:** 32-pin DIP (Dual In-line Package) or PLCC (Plastic Leaded Chip Carrier)  
- **Technology:** UV-erasable EPROM  
- **Programming Voltage (VPP):** 12.5V  

### **Descriptions:**  
- The **M27C4002-12C1** is a high-performance **4 Mbit EPROM** with a fast access time of **120 ns**.  
- It is designed for applications requiring non-volatile memory storage, such as firmware, BIOS, and embedded systems.  
- The device is **UV-erasable**, meaning data can be erased by exposing the chip to ultraviolet light before reprogramming.  
- It supports **standard microprocessor interfaces** and is compatible with industry-standard EPROM programmers.  

### **Features:**  
- **High-speed performance** (120 ns access time)  
- **Low power consumption** in standby mode  
- **Single 5V power supply** for read operations  
- **12.5V programming voltage**  
- **JEDEC-approved pinout** for compatibility  
- **Reliable data retention** (typically 10 years)  
- **Industrial-grade temperature range** available  

This information is based on STMicroelectronics' official datasheet for the **M27C4002-12C1** EPROM.
