Product Summary

The m29f400bt-90n1 is a 4 Mbit (512Kb×8 or 256Kb×16) non-volatile memory that can be read, erased and reprogrammed. These operations of the m29f400bt-90n1 can be performed using a single 5V supply. The m29f400bt-90n1 is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased.
