8 CMOS FLASH MEMORY
Publication Release Date: February 10, 2003

Revision A3
1. GENERAL DESCRIPTION
The W39L040 is a 4Mbit, 3.3-volt only CMOS flash memory organized as 512K
×
8 bits. For flexible
erase capability, the 4Mbits of data are divided into 8 uniform sectors of 64 Kbytes, which are
composed of 16 smaller even pages with 4 Kbytes. The byte-wide (
×
8) data appears on DQ7
DQ0.
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 of the W39L040 results in fast program/erase
operations with extremely low current consumption (compared to other comparable 3.3-volt flash
memory products). The device can also be programmed and erased by using standard EPROM
programmers.
