... GENERAL DESCRIPTION The W29C040 is a 4-megabit, 5-volt only CMOS page mode Flash Memory organized as 512K × 8 bits. The device can be written (erased and programmed) in-system with a standard 5V power supply. A 12-volt V is not required. The unique cell architecture of the W29C040 results in fast write (erase/ ...
