EN29SL400
4 Megabit (512K x 8-bit / 256K 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)
- 7 mA typical active read current
- 15 mA typical program/erase current
- 0.2 µA typical standby current
Flexible Sector Architecture:
- One 16 K-byte, two 8 K-byte, one 32 K-byte,
and seven 64 K-byte sectors (byte mode)
- One 8 K-word, two 4 K-word, one 16 K-word
and seven 32 K-word sectors (word mode)
Sector protection:
- Hardware locking of sectors to prevent
program or erase operations within individual
sectors
- Additionally, temporary Sector Unprotect
allows code changes in previously locked
sectors.
High performance program/erase speed
- Byte/Word program time: 5µs/7µs typical
- Sector erase time: 500ms typical

GENERAL DESCRIPTION
The EN29SL400 is an 4-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 524,288 bytes or 262144 words. Any byte can be programmed typically in 5µs. The
EN29SL400 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 EN29SL400 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.
This Data Sheet may be revised by subsequent versions 1
or modifications due to changes in technical specifications.
