Description and Introduction

256K-BIT [32K x 8] CMOS EPROM The **MX27C256QC-12** is a high-performance **256K-bit (32K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile data storage. Operating at a **120ns access time**, this component is well-suited for embedded systems, industrial controls, and legacy computing applications where fast and dependable memory access is essential.  

Featuring a **single 5V power supply**, the MX27C256QC-12 ensures compatibility with standard TTL logic levels, simplifying integration into existing circuit designs. Its **UV-erasable** capability allows for multiple reprogramming cycles, making it a flexible choice for development and prototyping. The chip is housed in a **32-pin ceramic quad flat package (CQFP)**, providing durability and efficient thermal dissipation.  

With a **wide operating temperature range** and robust noise immunity, the MX27C256QC-12 delivers stable performance in demanding environments. Its **low power consumption** further enhances its suitability for power-sensitive applications.  

As an industry-standard EPROM, the MX27C256QC-12 remains a dependable solution for systems requiring long-term data retention without the need for frequent updates. Its combination of speed, reliability, and reprogrammability ensures continued relevance in specialized and legacy electronic designs.
