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.

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, whi...
