W29D040C
512K x 8 CMOS FLASH MEMORY
Publication Release Date: January 1999

Revision A1
GENERAL DESCRIPTION
The W29D040C is an 4Mbit, 5-volt only CMOS flash memory organized as 512K
×
8 bits. For flexible
erase capability, the 4 Mbits 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 5V
power supply. A 12-volt V
PP
is not required. The unique cell architecture of the W29D040C 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 by using standard EPROM
programmers.
