Product Summary
The M29W640GT70NA6E is a 64 Mbit 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 M29W640GT70NA6E is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Program and Erase commands are written to the Command Interface of the memory. The M29W640GT70NA6E is organized into 128 uniform Blocks of 64 Kbytes each (or 32 Kwords each).
