M29W022BT Datasheet (ST Microelectronics) - 2 Mbit 256Kb x8 / Boot Block Low Voltage Single Supply Flash Memory

M29W022BT, 2 Mbit 256Kb x8 / Boot Block Low Voltage Single Supply Flash Memory

The M29W022B is a 2 Mbit (256Kb 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.
