Page mode Flash Memory, CMOS 3.0 Volt-only
FEATURES
•
Single power supply operation
- Full voltage range: 2.7 to 3.6 volts read and
write operations
•
High performance
- Access times as fast as 70 ns
•
8-word/16-byte page read buffer
•
16-word/32-byte write buffer reduces overall
programming time for multiple-word updates
•
Secured Silicon Sector region
- 128-word/256-byte sector for permanent,
secure identification through an 8-word/16-
byte random Electronic Serial Number
- Can be programmed and locked at the factory
or by the customer
•
Flexible Sector Architecture:
- Uniform sector models:
One hundred and twenty-eight uniform
32Kword/64Kbyte sectors
- Boot sector models:
Eight 8-Kbyte boot sectors on Top or Bottom
and one hundred twenty-seven 32Kword /
64Kbyte sectors.
•
Suspend and Resume commands for
Program and Erase operations
•
Write operation status bits indicate program
and erase operation completion
•
Support for CFI (Common Flash Interface)
•
Persistent methods of Advanced Sector
Protection
•
WP#/ACC input
- Accelerates programming time (when V
HH
is
applied) for greater throughput during system
production
- Protects first or last sector regardless of
sector protection settings
•
Hardware reset input (RESET#) resets
device
•
Ready/Busy# output (RY/BY#) detects
program or erase cycle completion
•
Minimum 100K program/erase endurance
cycles.
•

GENERAL DESCRIPTION
The EN29GL064 offers a fast page access time of 25 ns with a corresponding random access time as
fast as 70 ns. It features a Write Buffer that allows a maximum of 16 words/32 bytes to be programmed
in one operation, resulting in faster effective programming time than standard programming algorithms.
This makes the device ideal for today’s embedded applications that require higher density, better
performance and lower power consumption.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
