Description and Introduction

2 Meg (256k x 8) UV Erasable CMOS EPROM [Life-time buy] The **NM27C020Q-150** is a high-performance **2-megabit (256K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile data storage. Operating at a speed of **150 ns**, this component is well-suited for systems where fast access times are critical, such as embedded systems, industrial controls, and legacy computing platforms.  

Featuring a **single 5V power supply**, the NM27C020Q-150 offers low power consumption while maintaining robust performance. Its **UV-erasable** capability allows for repeated reprogramming, making it ideal for development and prototyping environments. The device supports a standard **parallel interface**, ensuring compatibility with a wide range of microprocessors and microcontrollers.  

With a **JEDEC-standard pinout**, the NM27C020Q-150 simplifies integration into existing designs. Its durable **ceramic or plastic package** options provide flexibility for different environmental and reliability requirements. Additionally, the EPROM includes **programming voltage detection**, enhancing data integrity during write operations.  

Engineers value the NM27C020Q-150 for its **long-term data retention** and **high noise immunity**, making it a dependable choice for mission-critical applications. While newer flash memory technologies have largely replaced EPROMs in modern designs, this component remains relevant in systems requiring proven, stable performance.

Application Scenarios & Design Considerations

2 Meg (256k x 8) UV Erasable CMOS EPROM [Life-time buy]

Alternative Part Number

  • M27C2001-15F1 --: 2 Mbit UV EPROM with the same 32-pin DIP pinout and 150 ns access time, a well-known drop-in replacement for the NM27C020Q-150.
  • AM27C020-150DC --: 2 Mbit CMOS EPROM in a 32-pin DIP package with 150 ns speed, functionally equivalent and widely available as a second source.
  • TMS27C020-15JL --: 2 Mbit EPROM with matching 150 ns access time and 32-pin DIP footprint, suitable as an alternative when the original part is unavailable.
  • AT27C020-15PC --: 2 Mbit OTP EPROM, 150 ns, same 32-pin DIP pinout and JEDEC-compatible interface, widely available alternative.
  • M27C2001-15C1 --: Same 2 Mbit EPROM density and 150 ns access time in a PLCC-32 package, suitable when the socket type allows a PLCC alternative to the original DIP device.
