Description and Introduction

256K-BIT [32K x 8] CMOS EPROM The **MX27C256PC-70** is a high-performance **256Kbit (32K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile data storage. Operating at a fast **70ns access time**, this component is well-suited for embedded systems, industrial controls, and legacy computing applications where speed and durability are critical.  

Featuring a single **5V power supply**, the MX27C256PC-70 offers low power consumption while maintaining robust performance. Its **UV-erasable** capability allows for multiple reprogramming cycles, making it ideal for development and prototyping environments. The device supports a standard **28-pin DIP (Dual In-line Package)**, ensuring compatibility with a wide range of circuit designs.  

With a **wide operating temperature range**, this EPROM is suitable for demanding conditions. Its **TTL-compatible inputs and outputs** simplify integration into existing digital systems. Additionally, the MX27C256PC-70 includes a **chip enable (CE) and output enable (OE) function**, providing efficient control over data retrieval.  

Engineers and designers favor this component for its **reliability, ease of use, and cost-effectiveness** in applications where firmware or fixed data storage is required. While newer flash memory technologies have largely replaced EPROMs in modern designs, the MX27C256PC-70 remains a viable choice for legacy systems and specialized use cases.
