W29C040T-90B Product details

GENERAL DESCRIPTION

The W29C040 is a 4-megabit, 5-volt only CMOS page modes Flah 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 VPPis 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 erased and programmed by using standard EPROM programmers.
