Overview
The M29W128GL70ZS3E is a 128Mb 3V Embedded Parallel NOR Flash memory device manufactured by Micron Technology Inc. This device is built on 90nm single-level cell (SLC) technology and is designed for applications requiring high performance and reliability. The M29W128GL70ZS3E supports asynchronous random and page read operations, and it features a uniform block memory organization that allows for independent erasure of blocks, preserving valid data while old data is purged.
The device operates with a single low-voltage supply and includes an on-chip program/erase controller that simplifies the programming and erasing process. It also supports various protection mechanisms, including hardware and software protection, to secure blocks from unwanted modifications.
