W29EE012
128K Ã 8 CMOS FLASH MEMORY
GENERAL DESCRIPTION
The W29EE012 is a 1-megabit, 5-volt only CMOS flash memory organized as 128K Ã 8 bits. The
device can be programmed and erased in-system with a standard 5V power supply. A 12-volt VPP is
not required. The unique cell architecture of the W29EE012 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.
