DESCRIPTION
The M29W004 is a non-volatile memory that may be erased electrically at the block or chip level and programmed in-system on a Byte-by-Byte basis using only a single 2.7V to 3.6V VCC supply. For Program and Erase operations the necessary high voltages are generated internally. The device can also be programmed in standard programmers.

■ M29W004T and M29W004B are replaced respectively by the M29W004BT and M29W004BB
■ 2.7 to 3.6V SUPPLY VOLTAGE for PROGRAM, ERASE and READ OPERATIONS
