Revision A3
1. GENERAL DESCRIPTION
The W39L040A is a 4Mbit, 3V/3.3V 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. 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
W39L040A 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.
