Description and Introduction

170 ns, Vcc=5V+/-5%, 262,144-bit (32k x 8) UV erasable CMOS PROM The **NMC27C256Q-17** is a high-performance **256Kbit (32K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable, non-volatile data storage. This component operates at a **170ns access time**, making it suitable for systems where speed and efficiency are critical.  

Featuring a **single 5V power supply**, the NMC27C256Q-17 simplifies integration into various digital circuits while maintaining low power consumption. Its **JEDEC-standard pinout** ensures compatibility with industry-standard EPROMs, facilitating easy upgrades or replacements in existing designs.  

The device supports **UV erasure**, allowing multiple reprogramming cycles, which is ideal for development and prototyping environments. Data retention is robust, with the EPROM maintaining stored information for extended periods under normal operating conditions.  

With a **wide operating temperature range**, the NMC27C256Q-17 is suitable for industrial and commercial applications where environmental resilience is essential. Its **tri-state output** capability enables seamless interfacing with microprocessors and other logic circuits.  

Engineers and designers value this EPROM for its **reliability, speed, and versatility**, making it a practical choice for firmware storage, embedded systems, and legacy hardware support. Its enduring design ensures continued relevance in both modern and legacy electronic systems.
