M29W004BT 4 Mbit 512Kb x8 / Boot Block Low Voltage Single Supply Flash Memory

The M29W004B is a 4 Mbit (512Kb x8) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) 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 M29W004B is fully backward compatible with the M29W004. The memory is.
