Description and Introduction

4M-BIT [512K x8] CMOS EPROM # Introduction to the MX27C4000MC-12 EPROM  

The **MX27C4000MC-12** is a high-performance **4 Megabit (512K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring non-volatile data storage. Manufactured with advanced CMOS technology, this component offers reliable performance with a fast access time of **120 ns**, making it suitable for embedded systems, industrial controls, and legacy computing applications.  

Featuring a **single 5V power supply**, the MX27C4000MC-12 ensures low power consumption while maintaining robust operation. Its **UV-erasable** capability allows for multiple reprogramming cycles, providing flexibility during development and testing phases. The device supports a standard **parallel interface**, ensuring compatibility with a wide range of microprocessors and microcontrollers.  

With a **28-pin plastic DIP (Dual In-line Package)**, the MX27C4000MC-12 is designed for easy integration into existing circuit designs. It includes a **chip enable (CE) and output enable (OE) control** for efficient power management and bus contention prevention.  

Engineers and developers working with legacy systems or requiring dependable EPROM solutions will find the MX27C4000MC-12 a reliable choice for firmware storage and system boot applications. Its durability and reprogrammability make it a practical component for long-term deployment in demanding environments.
