GENERAL DESCRIPTION

The EN29F002A / EN29F002AN is a 2-Megabit, electrically erasable, read/write non-volatile flash memory.

Organized into 256K words with 8 bits per word, the 2M of memory is arranged in seven sectors (with

top/bottom configuration), including one 16K Byte Boot Sector, two 8K Byte Parameter sectors, and four main

sectors (one 32K Byte and three 64K Byte). Any byte can be programmed typically at 10µs. The EN29F002A /

EN29F002AN features 5.0V voltage read and write operation. The access times are as fast as 45ns to

eliminate the need for WAIT states in high-performance microprocessor systems.

The EN29F002A / EN29F002AN has separate Output Enable (

), Chip Enable (

), and Write

Enable (

W E

) 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

minimum

100K

program/erase

cycles

each

sector.

This Data Sheet may be revised by subsequent versions

or modifications due to changes in technical specifications.
