Revision A5
GENERAL DESCRIPTION
The W29C040 is a 4-megabit, 5-volt only CMOS page mode EEPROM organized as 512K
×
8 bits.
The device can be written (erased and programmed) in-system with a standard 5V power supply. A
12-volt V
PP
is not required. The unique cell architecture of the W29C040 results in fast write (erase/
program) operations with extremely low current consumption compared to other comparable 5-volt
flash memory products. The device can also be written (erased and programmed) by using standard
EPROM programmers.
