GENERAL DESCRIPTION

The W29EE011 is a 1-megabit, 5-volt only CMOS flash memory organized as 128K ×8 bits. The device can be programmed and erased in-system with a standard 5V power supply. A 12-volt VPPis not required. The unique cell architecture of the W29EE011 results in fast program/erase operations with extremely low current consumption (compared toother comparable 5-volt flash memory products).
