Description and Introduction

NMOS 64K 8K x 8 UV EPROM The part **M27256-3F1** is a **256K (32K x 8) UV Erasable PROM** manufactured by **SGS (now STMicroelectronics)**.  

### **Specifications:**  
- **Memory Size:** 256Kbit (32K x 8)  
- **Technology:** UV Erasable PROM  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 250ns  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** 28-pin DIP (Dual In-line Package)  
- **Programming Voltage (VPP):** 12.5V  

### **Descriptions & Features:**  
- **UV Erasable:** Can be erased via exposure to ultraviolet light for reprogramming.  
- **Single 5V Power Supply:** Operates on standard 5V logic levels.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic circuits.  
- **Tri-State Outputs:** Allows for bus-oriented applications.  
- **High Reliability:** Designed for industrial and commercial applications.  

This part is commonly used in legacy computing, embedded systems, and industrial control applications requiring reprogrammable non-volatile memory.
