Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM The **NM27C256Q-100** 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 **100ns access time**, this component ensures efficient performance in embedded systems, industrial controls, and legacy computing applications.  

Featuring a **single 5V power supply**, the NM27C256Q-100 simplifies system integration while maintaining low power consumption. Its **UV-erasable** capability allows for multiple reprogramming cycles, making it suitable for development and prototyping. The device supports a **wide operating temperature range**, ensuring stability in varying environmental conditions.  

With a **standard 28-pin DIP (Dual In-line Package)**, the NM27C256Q-100 is compatible with many existing circuit designs. Its **tri-state output** enables easy interfacing with microprocessors and other logic circuits. Additionally, the EPROM includes a **chip enable (CE) and output enable (OE)** function for improved system control.  

Engineers and developers value the NM27C256Q-100 for its **durability, fast access speed, and reprogrammability**, making it a dependable choice for firmware storage and system boot applications. While newer flash memory technologies have emerged, this EPROM remains relevant in legacy and specialized systems requiring proven performance.
