Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM The **NM27C256Q-250** is a high-performance **32K x 8-bit (256Kbit) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile data storage. Operating at a **250ns access time**, this component is well-suited for systems where speed and data integrity are critical.  

Featuring a **single 5V power supply**, the NM27C256Q-250 simplifies system design while maintaining low power consumption. Its **UV-erasable** capability allows for multiple reprogramming cycles, making it ideal for development and prototyping environments. The device supports a standard **28-pin DIP (Dual In-line Package)**, ensuring compatibility with a wide range of legacy and modern systems.  

With a robust **CMOS technology** foundation, the NM27C256Q-250 offers improved noise immunity and reduced power dissipation compared to older EPROM variants. It includes a **chip enable (CE) and output enable (OE)** control for efficient memory management, enabling seamless integration into microprocessor-based designs.  

Engineers and developers often utilize this EPROM in embedded systems, industrial controls, and firmware storage applications where long-term data retention is essential. Its durability, reprogrammability, and performance make it a dependable choice for demanding electronic designs.
