Description and Introduction

4M-BIT [512KX8] CMOS EQUAL SECTOR FLASH MEMORY The **MX29F040PC-90** is a high-performance **4-megabit (512K x 8-bit) flash memory** component designed for applications requiring reliable, non-volatile data storage. Operating at **90ns access time**, it provides fast read operations, making it suitable for embedded systems, industrial controls, and consumer electronics.  

Built with **5V single power supply** compatibility, the MX29F040PC-90 features a **standard parallel interface**, ensuring easy integration with microcontrollers and other digital systems. Its **sector-erasable architecture** allows flexible data management, supporting both byte programming and sector erase operations.  

This flash memory device is organized into **eight 64KB sectors**, enabling efficient memory utilization. It includes built-in **write protection** mechanisms to prevent accidental data corruption and supports **100,000 program/erase cycles**, ensuring long-term durability.  

The **MX29F040PC-90** is housed in a **32-pin plastic DIP (Dual In-line Package)**, offering a compact and robust solution for various electronic designs. With its **low power consumption** and **high-speed performance**, it remains a dependable choice for developers seeking cost-effective, non-volatile memory solutions.  

Engineers and designers favor this component for its **compatibility with industry standards** and consistent performance in demanding environments. Its balance of speed, reliability, and ease of use makes it a practical option for a wide range of applications.

Alternative Part Number

  • AM29F040B-90PC --: Pin-compatible 4Mbit 5V flash with 90ns access time, widely used as a direct substitute for the MX29F040.
  • SST39SF040-70-4C-PHE --: 4Mbit 5V parallel flash in the same 32-pin PDIP package, faster 70ns speed grade, commonly used replacement.
  • W49F040A-90P --: 4Mbit 5V flash with 90ns access time and compatible pinout, suitable drop-in alternative when MXIC parts are unavailable.
  • SST39SF040-70-4C-PH --: 4Mbit 5V parallel flash in a 32-pin PDIP with faster 70ns access, commonly used as a drop-in replacement for MX29F040 designs.
  • W49F040-90P --: 4Mbit 5V flash memory with 90ns speed in a 32-pin DIP, offering comparable pinout and timing for legacy 29F040 sockets.
