Description and Introduction

256K-Bit (32K x 8) High Performance CMOS EPROM # Introduction to the NM27C256Q-150  

The **NM27C256Q-150** is a high-performance **256K-bit (32K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring non-volatile data storage. This component operates at a **150ns access time**, making it suitable for systems where reliable and fast data retrieval is essential.  

Built with **CMOS technology**, the NM27C256Q-150 offers low power consumption while maintaining robust performance. It features a **single 5V power supply**, simplifying integration into various digital systems. The device supports **standard EPROM programming methods**, allowing users to erase and reprogram data using ultraviolet light exposure, ensuring flexibility in development and testing phases.  

With a **wide operating temperature range**, this EPROM is well-suited for industrial, automotive, and embedded applications. Its **tri-state output** capability enables efficient bus sharing in multi-device configurations. Additionally, the NM27C256Q-150 is compatible with industry-standard pinouts, ensuring seamless replacement in legacy systems.  

Engineers and designers often utilize this component in firmware storage, microcontroller-based systems, and other applications where long-term data retention is critical. Its combination of speed, reliability, and reprogrammability makes it a dependable choice for demanding electronic designs.

Application Scenarios & Design Considerations

256K-Bit (32K x 8) High Performance CMOS EPROM

Alternative Part Number

  • M27C256B-15F1 --: Same 32K x 8 EPROM density and 150 ns access time, widely available pin-compatible DIP-28 replacement.
  • AT27C256R-15PU --: Equivalent 256Kbit OTP EPROM with 150 ns speed and DIP-28 pinout, good second-source option.
  • TMS27C256-15JL --: Pin-compatible 256Kbit EPROM with 150 ns access time, suitable as a functional substitute.
