Description and Introduction

NMOS 32K 4K x 8 UV EPROM The part **M2732A-25F1** is a **UV-erasable 32K (4K x 8) EPROM** manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Memory Size:** 32K (4K x 8 bits)  
- **Access Time:** 250 ns  
- **Supply Voltage (VCC):** 5V ± 5%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** 24-pin ceramic DIP (Dual In-line Package)  
- **Technology:** NMOS  
- **UV Erasable:** Requires exposure to ultraviolet light for erasure (typically 15-20 minutes under a UV lamp).  

### **Features:**  
- **High Reliability:** Designed for industrial and commercial applications.  
- **Single 5V Power Supply:** Compatible with standard TTL logic levels.  
- **Three-State Outputs:** Allows direct connection to a common bus.  
- **Low Power Consumption:** Suitable for power-sensitive designs.  
- **Programmable:** Can be reprogrammed after UV erasure.  

### **Applications:**  
- Microcontroller-based systems  
- Embedded firmware storage  
- Legacy computing and industrial control systems  

This part is now considered obsolete but was widely used in older electronic systems requiring reprogrammable non-volatile memory.
