Product Details
M29F200FT55M3E2 - Micron 2Mbit Parallel 5V Non-Volatile Flash Memory
The M29F200FT55M3E2 is a high-reliability, 2Mbit (256K x 8 or 128K x 16) parallel boot block Flash memory device. Operating on a 5.0V supply with a high-speed access time of 55ns, it is specifically designed for legacy system maintenance and embedded applications requiring secure firmware storage and robust data retention.
Architecture: Features a Top Boot block configuration, providing specialized sector protection for critical system startup code.
Overview & Technology
The M29F200FT55M3E2 belongs to the trusted M29F family of 5V parallel Flash. It utilizes x8/x16 selectable organization, allowing it to interface seamlessly with a wide range of 8-bit and 16-bit microprocessors via the BYTE# pin.
This device is a preferred solution for long-lifecycle industrial and automotive projects. Its ability to perform In-System Programming (ISP) without requiring additional high-voltage rails simplifies circuit design while maintaining the high endurance needed for mission-critical firmware updates.
About Micron Technology
Micron Technology, Inc. is a global leader in innovative memory and storage solutions. As one of the world's largest semiconductor manufacturers, Micron provides a broad portfolio of high-performance DRAM, NAND, and NOR Flash memory.
The M29F200 series was integrated into Micron's portfolio following the acquisition of Numonyx (a joint venture of STMicroelectronics and Intel). Micron continues to support these legacy parallel interfaces, ensuring that long-term industrial and automotive systems have access to reliable, high-quality non-volatile storage.
Package & Physical Dimensions
The M29F200FT55M3E2 is housed in the standard SO-44 (also known as PSOP44) package, designed for reliable through-hole or surface mount assembly in legacy PCB layouts.
- Package Type: Plastic Small Outline (SO)
- Pin Count: 44-Pin
- Pitch: 1.27 mm standard lead spacing
- Thermal Resistance: Optimized for industrial temperature ranges (-40°C to +125°C).
Key Advantages
Native support for 5V logic systems, eliminating the need for voltage level shifters.
Min. 20-year data retention and 100,000 program/erase cycles per block.
55ns access time (tACC) ensures zero-wait-state performance for many microcontrollers.
Uses JEDEC standard software commands for easy integration and firmware porting.
