DESCRIPTION

The M29F400 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 or Word by-Word basis using only a single 5V VCCsupply. For Program and Erase operations the necessary high voltages are generated internally. The device

can also be programmed in standard program mers.

M29F400T and M29F400B are replaced respectively by the M29F400BT and M29F400BB
