GENERAL DESCRIPTION
The EN29LV160A is a 16-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 2,097,152 bytes or 1,048,576 words. Any byte can be programmed typically in 8µs.
The EN29LV160A features 3.0V voltage read and write operation, with access times as fast as
70ns to eliminate the need for WAIT states in high-performance microprocessor systems.
The EN29LV160A 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.
