GENERAL DESCRIPTION
The EN29LV040A is a 4-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 524,288 bytes. Any byte can be programmed typically in 8µs. The EN29LV040A
features 3.0V voltage read and write operation, with access times as fast as 45ns to eliminate the
need for WAIT states in high-performance microprocessor systems.
The EN29LV040A has separate Output Enable ( OE ), Chip Enable ( CE ), and Write Enable (WE)
controls, which eliminate bus contention issues. This device is designed to allow either single
Sector or full chip erase operation, where each Sector can be individually protected against
program/erase operations or temporarily unprotected to erase or program. The device can sustain a
minimum of 100K program/erase cycles on each Sector.
This Data Sheet may be revised by subsequent versions 1
or modifications due to changes in technical specifications.
