Description and Introduction

512K-BIT [64Kx8] CMOS EPROM **Introduction to the MX27C512QC-90 EPROM**  

The MX27C512QC-90 is a high-performance 512K-bit (64K x 8) erasable programmable read-only memory (EPROM) designed for applications requiring reliable non-volatile data storage. Operating at a 90ns access time, this component ensures efficient performance in systems where fast data retrieval is essential.  

Featuring a single 5V power supply, the MX27C512QC-90 is compatible with standard microprocessor interfaces, making it suitable for embedded systems, industrial controls, and legacy computing applications. Its UV-erasable design allows for multiple reprogramming cycles, offering flexibility during development and testing phases.  

The device includes a standby mode to reduce power consumption when inactive, enhancing energy efficiency. With a robust architecture and industrial-grade reliability, it meets stringent operational requirements in demanding environments.  

Packaged in a 32-pin plastic leaded chip carrier (PLCC), the MX27C512QC-90 provides a compact and durable solution for circuit integration. Its compatibility with industry-standard pinouts ensures seamless replacement in existing designs.  

For engineers and developers working with legacy or specialized systems, the MX27C512QC-90 remains a dependable choice for non-volatile memory storage, balancing speed, power efficiency, and reprogrammability.

Application Scenarios & Design Considerations

512K-BIT [64Kx8] CMOS EPROM

Alternative Part Number

  • AM29F512B-90JC --: 512Kbit flash memory in a similar PLCC package with 90ns access time, a common drop-in replacement for the MX27C512.
  • SST39SF512-70-4C-NH --: 512Kbit flash memory with compatible pinout and faster 70ns access, widely used as a substitute for MX27C512 devices.
  • AT29C512-90JC --: 512Kbit CMOS flash memory in PLCC with 90ns speed, functionally equivalent and readily available as an alternative.
  • AM27C512-90DC --: Same 512Kbit (64K x 8) UV EPROM with 90 ns access time in a 28-pin DIP package; pin-compatible and widely available as a direct functional replacement.
  • M27C512-90B6 --: 512Kbit EPROM with 90 ns speed grade and matching pinout; a well-established second-source equivalent for the MX27C512 series.
  • TMS27C512-90JL --: Equivalent 512Kbit CMOS EPROM at 90 ns in a 28-pin package; drop-in compatible for most read-only memory applications.
