M50FLW040AK5规格书详情
Summary description
The M50FLW040 is a 4 Mbit (512 Kb 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 in production lines, an optional 12 V power supply can be used to reduce the erasing and programming time.
The memory is divided into 8 Uniform Blocks of 64 KBytes each, three of which are divided into 16 uniform sectors of 4 KBytes each (see Appendix A for details). All blocks and sectors 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 their contents.
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 to control the memory is consistent with the JEDEC standards.
