Product Summary

The M29W640GB70NA6E is a 64 Mbit (8Mb×8 or 4Mb×16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode. The M29W640GB70NA6E is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. An on-chip Program/Erase Controller simplifies the process of programming or erasing the memory by taking care of all of the special operations that are required to update the memory contents.
