Description and Introduction

200 ns, Vcc=5V+/-5%, 262,144-bit (32k x 8) high speed version UV erasable CMOS PROM **Introduction to the NMC27C256BQ20 EPROM**  

The NMC27C256BQ20 is a high-performance 256K-bit (32K x 8) erasable programmable read-only memory (EPROM) designed for applications requiring non-volatile data storage. This CMOS-based component features a fast access time of 200ns, making it suitable for systems where quick data retrieval is essential.  

Housed in a 28-pin ceramic DIP package, the NMC27C256BQ20 offers reliable operation with a single 5V power supply, ensuring compatibility with a wide range of digital systems. Its UV-erasable design allows for multiple reprogramming cycles, providing flexibility during development and testing phases.  

Key features include a low standby current, TTL-compatible inputs and outputs, and a straightforward interface for easy integration into microprocessor-based designs. The device is commonly used in firmware storage, industrial control systems, and legacy computing applications where durability and reprogrammability are critical.  

With robust performance and industry-standard pinout, the NMC27C256BQ20 remains a dependable choice for engineers working with embedded systems requiring non-volatile memory solutions. Its balance of speed, power efficiency, and reprogrammability ensures continued relevance in specialized electronic applications.
