M29F040B - 4 Mbit 512Kb x8 / Uniform Block Single Supply Flash Memory

The M29F040B is a 4 Mbit (512Kb x8) non-volatile memory that can be read, erased and reprogrammed.

These operations 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 M29F040B is fully backward compa
