Description and Introduction

131,072-Bit (16K x 8) High Performance CMOS EPROM The **NM27C128Q-250** is a high-performance **128K-bit (16K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile data storage. Operating at a fast **250 ns access time**, this component is well-suited for systems demanding quick data retrieval, such as embedded computing, industrial controls, and legacy computing platforms.  

Fabricated using advanced CMOS technology, the NM27C128Q-250 offers **low power consumption** while maintaining robust performance. It features a **single 5V power supply**, simplifying integration into various circuit designs. The device supports **standard EPROM functionality**, including UV erasure for reprogramming, making it a flexible solution for firmware and code storage in development environments.  

With a **wide operating temperature range**, the NM27C128Q-250 ensures stability in diverse conditions, enhancing its suitability for industrial and automotive applications. Its **JEDEC-standard pinout** ensures compatibility with existing EPROM sockets, facilitating straightforward upgrades or replacements in legacy systems.  

Engineers and developers value this component for its **durability, speed, and ease of use**, making it a reliable choice for applications where long-term data retention and reprogrammability are critical. The NM27C128Q-250 remains a practical solution in scenarios requiring dependable non-volatile memory with proven performance.
