The M29W640FT70N6E is a 64MB non-volatile Flash 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 memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Blocks can be protected in units of 256Kb, to prevent accidental program or erase commands from modifying the memory. Program and erase commands are written to the command Interface of the memory. 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. The end of a program or erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards.
Asynchronous random/page read
Random access - 70ns
Programming time - 10μs per byte/word typical
Program/erase controller - embedded byte/word program algorithms
Program/erase suspend and resume - read from any block during program suspend
Read and program another block during erase suspend
Unlock bypass program command - Faster production/batch programming
VPP/WP Pin for fast program and write protect
Temporary block unprotection mode
Common flash interface - 64-bit security code
Extended memory block
Extra block used as security block or to store additional information
Low power consumption - standby and automatic standby
