Description and Introduction

16,384-Bit (2048 x 8) CMOS EPROM The **NMC27C16BQ-200** is a high-performance **EPROM (Erasable Programmable Read-Only Memory)** integrated circuit designed for reliable data storage in embedded systems and legacy computing applications. With a storage capacity of **16 kilobits (2K x 8 bits)**, this component provides non-volatile memory retention, ensuring data persistence even when power is removed.  

Fabricated using **NMOS technology**, the NMC27C16BQ-200 operates at a **200ns access time**, making it suitable for systems requiring moderate-speed memory access. It features a single **5V power supply**, simplifying integration into various digital designs. The device supports **UV erasure**, allowing for reprogramming after exposure to ultraviolet light, which makes it ideal for prototyping and firmware development.  

Key characteristics include a **wide operating temperature range**, robust noise immunity, and compatibility with standard microprocessor interfaces. Its **24-pin DIP (Dual In-line Package)** ensures easy mounting on breadboards or PCBs.  

While newer flash memory technologies have largely replaced EPROMs in modern designs, the NMC27C16BQ-200 remains relevant in industrial control systems, retro computing, and applications requiring long-term stability without frequent updates. Its durability and straightforward interface make it a dependable choice for engineers working with legacy hardware.

Application Scenarios & Design Considerations

16,384-Bit (2048 x 8) CMOS EPROM

Alternative Part Number

  • M27C16-20F1 --: 16K-bit (2K x 8) UV EPROM in a 24-pin CERDIP with 200 ns access time, functionally equivalent to the NMC27C16BQ-200 and pin-compatible.
  • TMS27C16-20JL --: 16K-bit UV EPROM with 200 ns access time in a 24-pin ceramic package, a direct functional replacement for the original device.
  • HN27C16AG-20 --: 2K x 8 UV EPROM rated at 200 ns in a 24-pin package, offering the same density, speed, and interface as the source part.
