GENERAL DESCRIPTION
The W49F002U is a 2-megabit, 5-volt only CMOS flash memory organized as 256K
device can be programmed and erased in-system with a standard 5V power supply. A 12-volt V
not required. The unique cell architecture of the W49F002U results in fast program/erase operations
with extremely low current consumption (compared to other comparable 5-volt flash memory
products). The device can also be programmed and erased using standard EPROM programmers.
