Uniform Sector Flash Memory
FEATURES
•
Single power supply operation
- Full voltage range: 2.7 to 3.6 volts for read,
erase and program operations
•
Low power cons
umption (typical values at 5
MHz)

(CFI).
Hardware features:
•
RESET# hardware reset pin
- Hardware method to reset the device to read
mode.
•
WP# input pin
- Write Protect (WP#) function allows
protection of first or last 32K-word sector,
regardless of previous sector protect status
•
ACC input pin
- Acceleration (ACC) function provides
accelerated program times for higher
throughput for manufacturing.
•
JEDEC standards compatible
- Pinout and software compatible with single-
power supply Flash standard
•
Manufactured on 0.18μm process
technology

GENERAL DESCRIPTION
The EN29LV641H/L / EN29LV640U is a 64-Megabit (4,194,304x16), electrically erasable, read/write
non-volatile flash memory. Any word can be programmed typically in 8µs. This device is entirely
command set compatible with the JEDEC single-power-supply Flash standard.
The EN29LV641H/L / EN29LV640U is designed to allow either single Sector or full Chip erase
operation, where each Sector Group can be 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.
