M29W004BB Datasheet (ST Microelectronics) - 4 Mbit 512Kb x8 / Boot Block Low Voltage Single Supply Flash Memory

M29W004BB, 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.
