Description and Introduction

262,144-Bit (32K x 8) High Performance CMOS PROM # Introduction to the NM27C256  

The NM27C256 is a high-performance 256 kilobit (32K x 8) UV-erasable programmable read-only memory (EPROM) chip. Designed for applications requiring non-volatile data storage, it offers reliable performance and ease of reprogramming. The device operates on a single 5V power supply, making it compatible with a wide range of digital systems.  

Featuring a fast access time, the NM27C256 is suitable for embedded systems, industrial controls, and legacy computing applications where firmware or fixed data storage is essential. Its UV-erasable capability allows for multiple reprogramming cycles, providing flexibility during development and testing phases.  

The NM27C256 follows a standard 28-pin DIP (Dual In-line Package) configuration, ensuring compatibility with existing circuit designs. Data retention is robust, with the chip maintaining stored information for extended periods, even without power.  

While modern flash memory has largely replaced EPROMs in many applications, the NM27C256 remains relevant in scenarios requiring proven reliability and straightforward interfacing. Its straightforward programming and erasure process make it a practical choice for engineers working with legacy hardware or specialized systems.  

Overall, the NM27C256 exemplifies the durability and functionality of classic EPROM technology, continuing to serve in niche applications where its characteristics are advantageous.
