Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM The **NM27C256QE--250** is a high-performance **256K-bit (32K x 8) 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 fast read operations are essential, such as embedded computing, industrial control, and legacy hardware upgrades.  

Featuring a **single 5V power supply**, the NM27C256QE--250 ensures compatibility with standard TTL logic levels, simplifying integration into existing designs. Its **UV-erasable** capability allows for multiple reprogramming cycles, making it ideal for prototyping and development environments. The chip's **28-pin DIP (Dual In-line Package)** provides a robust and widely supported form factor for both breadboard and PCB applications.  

With a **wide operating temperature range**, the NM27C256QE--250 maintains stable performance in demanding conditions. Its **low power consumption** in standby mode enhances energy efficiency, while the **tri-state output** enables seamless bus sharing in multi-device configurations.  

Engineers and designers continue to rely on this EPROM for its durability, speed, and versatility in preserving critical firmware and system data. Its proven architecture ensures backward compatibility with earlier EPROM models, making it a dependable choice for legacy and modern systems alike.
