Description and Introduction

2 Meg (256k x 8) UV Erasable CMOS EPROM [Life-time buy] **Introduction to the NM27C020Q120 Electronic Component**  

The NM27C020Q120 is a high-performance, 2-megabit (256K x 8) ultraviolet-erasable programmable read-only memory (UV-EPROM) designed for applications requiring reliable non-volatile data storage. Operating at a speed of 120ns, this component is well-suited for embedded systems, industrial controls, and legacy computing applications where firmware or critical data must be retained without power.  

Featuring a single 5V power supply, the NM27C020Q120 offers low power consumption while maintaining robust performance. Its UV-erasable functionality allows for multiple reprogramming cycles, making it a flexible solution for development and prototyping. The device is housed in a 32-pin ceramic or plastic DIP package, ensuring compatibility with standard PCB designs.  

With a wide operating temperature range and strong noise immunity, the NM27C020Q120 is built to endure demanding environments. Its straightforward interface and industry-standard pinout simplify integration into existing systems. While newer flash memory technologies have largely replaced EPROMs in modern designs, the NM27C020Q120 remains a dependable choice for applications requiring long-term stability and proven reliability.  

This component exemplifies the durability and precision of legacy memory solutions, making it a valuable option for specialized or maintenance-critical systems.

Alternative Part Number

  • M27C2001-12F1 --: 2 Mbit UV EPROM with the same 32-pin DIP pinout and 120 ns access time, a direct functional replacement from a different manufacturer and series.
  • AM27C020-120DC --: 2 Mbit CMOS EPROM in a 32-pin DIP with 120 ns speed, pin-compatible with the NM27C020Q120 and widely available.
  • TMS27C020-12JL --: 2 Mbit EPROM with matching 32-pin DIP footprint and 120 ns timing, suitable as a drop-in substitute from a different series.
