M29F200BB General Description
The M29F200B is a 2 Mbit (256Kb x8 or 128Kbx16) non-volatile memory that can be read, erased and reprogrammed. These operations can be per-formed using a single 5V supply. On power-up the memory defaults to its Read mode where it can beread in the same way as a ROM or EPROM. The M29F200B is fully backward compatible with the M29F200.
The memory is divided into blocks that can beerased independently so it is possible to preservevalid data while old data is erased. Each block canbe protected independently to prevent accidental Program or Erase commands from modifying thememory. Program and Erase commands are writ-ten to the Command Interface of the memory. Anon-chip Program/Erase Controller simplifies the process of programming or erasing the memory bytaking 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.
