EN29SL800
8 Megabit (1024K x 8-bit / 512K x 16-bit) Flash Memory
Boot Sector Flash Memory, CMOS 1.8 Volt-only
FEATURES
•
Single power supply operation
- Full voltage range:1.65-2.2 volt for read and
write operations.
- Ideal for battery-powered applications.
•
High performance
- Access times as fast as 70 ns
•
Low power consumption (typical values at 5
MHz)
- 15 mA typical active read current
- 15 mA typical program/erase current
- 0.2
μA
typical standby current
•
Flexible Sector Architecture:
- One 16-Kbyte, two 8-Kbyte, one 32-Kbyte,
and fifteen 64-Kbyte sectors (byte mode)
- One 8-Kword, two 4-Kword, one 16-Kword
and fifteen 32-Kword sectors (word mode)

GENERAL DESCRIPTION
The EN29SL800 is an 8-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 1,048,576 bytes or 524,288 words. Any byte can be programmed typically in 5µs. The
EN29SL800 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 EN29SL800 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.
