DESCRIPTION

The M59DR008 is an 8 Mbit non-volatile Flash memory that may be erased electrically at block level and programmed in-system on a Word-by-Word basis using a 1.65V to 2.2V VDD supply for the circuitry. For Program and Erase operations the necessary high voltages are generated internally. The device supports asynchronous page mode from all the blocks of the memory array.
