Product Summary

The M29F400BB-70N6E is a 4 Mbit (512 Kb x8 or 256 Kb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single 5V supply. On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM. The M29F400BB-70N6E is fully backward compatible with the M29F400. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Each block of the M29F400BB-70N6E can be protected independently to prevent accidental Program or Erase commands from modifying the memory.
