EN29LV400
4 Megabit (512K x 8-bit / 256K x 16-bit) Flash Memory
Boot Sector Flash Memory, CMOS 3.0 Volt-only
FEATURES
•
3V, single power supply operation
- Full voltage range: 2.7-3.6 volt read and write
operations for battery-powered applications.
- Regulated voltage range: 3.0-3.6 volt read
and write operations and for compatibility with
high performance 3.3 volt microprocessors.
•
High performance
- Access times as fast as 45 ns
•
Low power consumption (typical values at 5
MHz)
- 7 mA typical active read current
- 15 mA typical program/erase current
- 1
µA
typical standby current (standard access
time to active mode)
•
Flexible Sector Architecture:
- One 16 Kbyte, two 8 Kbyte, one 32 Kbyte,
and seven 64 Kbyte sectors (byte mode)
- One 8 Kword, two 4 Kword, one 16 Kword
and seven 32 Kword sectors (word mode)
- Supports full chip erase
- Individual sector erase supported
- Sector protection:
Hardware locking of sectors to prevent
program or erase operations within individual
sectors
Additionally, temporary Sector Group
Unprotect allows code changes in previously
locked sectors.
•

GENERAL DESCRIPTION
The EN29LV400 is a 4-Megabit, electrically erasable, read/write non-volatile flash memory,
organized as 524,288 bytes or 256,144 words. Any byte can be programmed typically in 8µs. The
EN29LV400 features 3.0V voltage read and write operation, with access times as fast as 45ns to
eliminate the need for WAIT states in high-performance microprocessor systems.
The EN29LV400 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.
