Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM The **NM27C256N90** is a high-performance **32K x 8-bit (256Kb) UV-erasable programmable read-only memory (EPROM)** designed for reliable data storage in embedded systems and industrial applications. Featuring a fast access time of **90ns**, this component ensures efficient operation in demanding environments where speed and data integrity are critical.  

Built with **CMOS technology**, the NM27C256N90 offers low power consumption while maintaining robust performance. Its **single 5V power supply** simplifies integration into various circuit designs, making it a versatile choice for legacy and modern systems alike. The EPROM is organized in a **byte-wide format**, allowing straightforward interfacing with microprocessors and microcontrollers.  

A key feature of this device is its **UV-erasable** capability, enabling users to reprogram the memory after exposure to ultraviolet light. This makes it suitable for prototyping and development phases where firmware updates are frequent. The NM27C256N90 also includes a **programming voltage (VPP) of 12.5V**, ensuring reliable write operations.  

With a durable **ceramic or plastic DIP package**, the NM27C256N90 provides excellent thermal and electrical stability. Its compatibility with industry-standard pinouts ensures seamless replacement in existing designs. Ideal for applications requiring non-volatile storage, this EPROM remains a dependable solution for embedded control systems, telecommunications, and industrial automation.
