M29F800FT55M3E2

Memory IC Overview

The M29F800FT55M3E2 is a Micron Parallel NOR Flash memory device with an 8Mb density. It features a top boot block configuration and supports asynchronous access times of 55ns. The component operates on a single 5V supply (4.5–5.5V) and offers independent block erase capabilities with protection against accidental programming. It includes an embedded program/erase controller, supports erase suspend/resume modes, and provides electronic signatures for identification.

Memory IC Feature Summary

• Supports READ, ERASE, and PROGRAM operations using a single low-voltage supply
• Features an embedded program/erase controller for simplified update management
• Provides independent block protection to prevent accidental data modification
• Includes erase suspend and resume modes for flexible operation

Memory IC Applications

• Microprocessor initialization code storage
• Parameter storage in embedded systems
• Application code storage in nonvolatile memory environments

Memory IC Procurement Notes

Verify the specific ordering suffix 'M' indicates the SO 44 package variant rather than the TSOP 48 option. Confirm that the temperature range corresponds to Automotive Grade 3 (-40°C to +125°C). Ensure compatibility with JEDEC standard command sets for your controller interface. Check current availability as this series may have limited production status.

Memory IC Selection Notes

Select this part when a top boot architecture is required for reliable system startup code execution. The 55ns speed suits applications needing moderate access times without complex timing constraints. Consider the 8Mb capacity relative to available address lines. Verify that the 5V supply requirement aligns with the system power rails.

Memory IC Part Context

This component belongs to the Micron M29F family of 5V Parallel NOR Flash memories. It shares architectural similarities with the M29F200, M29F400, and M29F160 variants, differing primarily in density and block organization. The 'FT' designation specifically denotes the Top Boot Block layout, distinguishing it from the Bottom Boot 'FB' versions within the same speed and package specifications.

Memory IC Replacement Considerations

Direct substitutes include other M29F800FT variants with different package options such as N (TSOP 48). Cross-referencing with Alliance Memory equivalents like the AM29F800 series may be possible if pinouts and electrical characteristics match exactly.
