SUMMARY DESCRIPTION
The M50FW016 is a 16 Mbit (2Mb x8) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (3.0 to 3.6V) supply. For fast programming and fast erasing, an optional 12V power supply can be used to reduce the programming and the erasing times.
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 individually 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.
