M29W128GH7AN6F TR

Memory IC Overview

The M29W128GH7AN6F TR is a 128Mb (8M x 16 or 16M x 8) asynchronous parallel NOR Flash memory manufactured by Micron Technology. It operates on a single VCC supply of 2.7V to 3.6V for program, erase, and read operations. The device features a 70ns random access speed and supports page reads with 25ns or 30ns access times. It utilizes a 56-pin TSOP package (N) measuring 14mm x 20mm. The 'A' suffix indicates automotive qualification, while '6' denotes the -40°C to +125°C temperature range. The 'F' suffix specifies tape and reel shipping options.

Memory IC Feature Summary

• Supports asynchronous random and page reads across all blocks with embedded program/erase controllers.
• Features fast buffered programming with 32-word write buffers and enhanced 256-word buffer capabilities in x16 mode.
• Includes hardware protection via VPP/WP# pin and multiple software protection schemes including password and nonvolatile modes.
• Contains an extended memory block for permanent secure identification and supports Common Flash Interface standards.

Memory IC Applications

• Embedded code storage for boot and application execution
• In-system programming for firmware updates
• Automotive electronic control units requiring high reliability

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, temperature grade, and shipping configuration. Confirm automotive qualification status if operating in extreme environments. Ensure voltage levels align with system requirements before integration.

Memory IC Selection Notes

Select this component for applications requiring uniform block architecture and robust data protection mechanisms. Consider the 70ns access time for system timing constraints. Verify compatibility with existing microprocessor interfaces regarding CE#, OE#, and WE# signal controls.

Memory IC Part Context

This part belongs to the M29W series of 3V Embedded Parallel NOR Flash memories. It shares architectural similarities with the M29W128GL variant but differs in block protection defaults. The GH designation indicates the highest block is protected by the VPP/WP# pin.

Memory IC FAQ

What is the function of the VPP/WP# pin?

The VPP/WP# pin provides hardware protection for the first or last block and enables faster programming when connected to a higher voltage source.

How does the device handle program and erase operations?

Operations are controlled via standard command sequences sent to the command interface, managed by an on-chip program/erase controller that handles internal timing and verification.
