GENERAL DESCRIPTION
The W49V002A is a 2 -megabit, 3.3-volt only CMOS flash memory organized as 256K x  8 bits. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt V PP is not required. The unique cell architecture ofthe W49V002A results in fast program/erase operations with extremely low current consumption.
