W29C011A

128K x 8 CMOS FLASH MEMORY

Winbond 

Preliminary W29C011A

128K × 8 CMOS FLASH MEMORY

GENERAL DESCRIPTION

The W29C011A 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 VPP is

not required. The unique cell architecture of the W29C011A 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.
