Description and Introduction

4 Meg (256K x 16) High Performance CMOS EPROM [Life-time buy] The **NM27C240Q120** is a high-performance **EPROM (Erasable Programmable Read-Only Memory)** integrated circuit designed for applications requiring reliable, non-volatile data storage. With a capacity of **4 megabits (512K x 8)**, this component is well-suited for embedded systems, industrial controls, and legacy computing applications where firmware or critical data must be retained without power.  

Operating at **5V**, the NM27C240Q120 features a **120ns access time**, ensuring efficient data retrieval in time-sensitive environments. Its **one-time programmable (OTP)** nature makes it ideal for finalized code storage, while its **JEDEC-standard pinout** ensures compatibility with industry designs. The device supports **parallel programming**, allowing straightforward integration into development and production workflows.  

Encased in a **32-pin plastic DIP (Dual In-line Package)**, the NM27C240Q120 is robust and easy to handle for prototyping and testing. Its **wide operating temperature range** enhances reliability in demanding conditions.  

Though newer flash memory technologies have largely replaced EPROMs in modern designs, the NM27C240Q120 remains relevant in applications requiring long-term stability, radiation resistance, or legacy system support. Engineers working with older hardware or specialized industrial systems may still find this component a dependable solution.  

For precise specifications, always refer to the manufacturer’s datasheet to ensure compatibility with your design requirements.

Alternative Part Number

  • M27C4001-12F1 --: 4 Mbit UV EPROM in the same 32-pin DIP package with 120 ns access time, a direct functional replacement for the 4 Mbit NM27C240.
  • AM27C400-120DC --: 4 Mbit CMOS EPROM with 120 ns speed and compatible pinout, widely used as a drop-in substitute for Fairchild NM27C series devices.
  • M27C4002-12F1 --: 4 Mbit EPROM with 120 ns access time and matching organization, suitable as an alternative when the exact Fairchild part is unavailable.
  • TMS27C240-12JL --: 4 Mbit EPROM with 120 ns access time in a 40-pin package, matching the original NM27C240Q120 specifications.
