Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM The **NM27C256V120** 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. This component operates at a **120ns access time**, making it suitable for systems where speed and data integrity are critical.  

Featuring a **single 5V power supply**, the NM27C256V120 ensures compatibility with standard TTL logic levels, simplifying integration into various digital circuits. Its **UV-erasable** capability allows for multiple reprogramming cycles, offering flexibility during development and testing phases. The chip utilizes a **28-pin DIP (Dual In-line Package)**, a widely adopted form factor that facilitates straightforward PCB mounting.  

Key applications include **firmware storage, embedded systems, and legacy computing devices** where long-term data retention is essential. The NM27C256V120 is known for its **low power consumption** in standby mode, enhancing energy efficiency in power-sensitive designs.  

With robust performance characteristics and a proven architecture, this EPROM remains a dependable choice for engineers working with older or specialized electronic systems that require reprogrammable memory solutions. Its balance of speed, reliability, and ease of use makes it a practical component in both industrial and consumer electronics.
