• Ready/Busy# output (RY/BY#)

- Provides a hardware method for detecting

program or erase cycle completion.

• Hardware reset pin (Reset#)

- Resets internal state machine to read mode

GENERAL DESCRIPTION

The EN29F080 is a 8-Megabit, electrically erasable, read/write non-volatile flash memory. Organized

into 1024K words with 8 bits per word, the 8M of memory is arranged in eight uniform sectors of

64Kbytes each.

Any byte can be programmed typically in 10µs.

The EN29F080 features 5.0V

voltage read and write operation, with access times as fast as 45ns to eliminate the need for WAIT

states in high-performance microprocessor systems.

controls, which eliminate bus contention issues. This device is designed to allow either single (or

multiple) 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.
