GENERAL DESCRIPTION
The EN39SL801 is an 8-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 524,288 words. Any word can be programmed typically in 8µs.The EN39SL801 features 1.8V
voltage read and write operation, with access time as fast as 70ns to eliminate the need for WAIT
statements in high-performance microprocessor systems.
The EN39SL801 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/Block or full
chip erase operation, where each block can be individually protected against program/erase operations or
chip unprotected to erase or program. The device can sustain a minimum of 100K program/erase cycles on
each sector or block.
