W29C042
512K
× 8 CMOS FLASH MEMORY
Publication Release Date: February 18, 2002
- 1 -
Revision A2
GENERAL DESCRIPTION
The W29C042 is a 4-megabit, 5-volt only CMOS page mode Flash Memory organized as 512K
× 8
bits. The device can be written (erased and programmed) in-system with a standard 5V power supply.
A 12-volt VPP is not required. The unique cell architecture of the W29C042 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 erased and programmed by using standard EPROM
programmers.
