Product Summary
The M29F040B70N6 is a 4 Mbit (512Kb x8) non-volatile memory that can be read, erased and reprogrammed. The M29F040B70N6 operation 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 M29F040B70N6 is fully backward compatible with the M29F040.
