DESCRIPTION

The M29W008A 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.
