Description and Introduction

256K-BIT [32K x 8] CMOS EPROM The **MX27C256QC-45** is a high-performance **256Kbit (32K x 8) UV-erasable programmable read-only memory (EPROM)** designed for applications requiring reliable non-volatile storage. Operating at a **45ns access time**, this component ensures fast data retrieval, making it suitable for embedded systems, industrial controls, and legacy computing applications.  

Featuring a **single 5V power supply**, the MX27C256QC-45 simplifies system integration while maintaining low power consumption. Its **UV-erasable** capability allows for repeated reprogramming, offering flexibility during development and testing phases. The device is organized in a **32K x 8 configuration**, providing straightforward interfacing with 8-bit microprocessors.  

The **DIP-28 package** ensures compatibility with standard sockets and prototyping boards, facilitating easy replacement or upgrades. With a **wide operating temperature range**, this EPROM is robust enough for demanding environments.  

Key features include:  
- **256Kbit capacity (32K x 8)**  
- **45ns access time**  
- **UV-erasable and reprogrammable**  
- **Single 5V power supply**  
- **DIP-28 package for broad compatibility**  

The MX27C256QC-45 remains a dependable choice for engineers seeking a durable, high-speed EPROM solution for legacy or specialized applications. Its balance of performance and reliability makes it a valuable component in various electronic systems.

Application Scenarios & Design Considerations

256K-BIT [32K x 8] CMOS EPROM

Alternative Part Number

  • AT27C256R-45JU --: 256Kbit OTP EPROM with 45ns access time in PLCC package, pin-compatible and functionally equivalent to the MX27C256.
  • SST27SF256-70-4C-NH --: 256Kbit CMOS EPROM with similar organization and PLCC footprint, suitable drop-in replacement with adequate speed for most designs.
  • M27C256B-45XF1 --: 256Kbit UV EPROM with 45ns access time, same density and pinout, widely available alternative for legacy designs.
  • W27C512-45Z --: 512Kb EPROM with 45 ns access time that is backward-compatible for 256Kb sockets when upper address is tied off; useful when the exact 256Kb part is scarce.
