DESCRIPTION
The M29W800 is a non-volatile memory that may be erased electrically at the block or chip level and programmedin-system ona Byte-by-Byteor Wordby-Word basisusing only a single2.7V 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.

■ M29W800T and M29W800B are replaced respectively by the M29W800AT and M29W800AB
■ 2.7V to 3.6V SUPPLY VOLTAGE for PROGRAM, ERASE and READ OPERATIONS
■ FASTACCESS TIME: 90ns
■ FAST PROGRAMMING TIME
   – 10µs by Byte / 20µs by Word typical
■ PROGRAM/ERASE CONTROLLER (P/E.C.)
   – Program Byte-by-Byte or Word-by-Word
   – Status Register bits and Ready/Busy Output
■ MEMORY BLOCKS
