Am29LV641G
64 Megabit (4 M x 16-Bit) CMOS 3.0 Volt-only
Uniform Sector Flash Memory with VersatileI/O
Control
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
■
Single power supply operation
— 2.7 to 3.6 volt read, erase, and program operations
■
SecSi
(Secured Silicon) Sector region
— 128-word sector for permanent, secure identification
through an 8-word random Electronic Serial Number
— May be programmed and locked at the factory or by
the customer
— Accessible through a command sequence
■
VersatileI/O
control
— Device generates data output voltages and tolerates
data input voltages as determined by the voltage on
the V
IO
pin
■
Manufactured on 0.18 μm process technology
■
Flexible sector architecture
— One hundred twenty-eight 32 Kword sectors
■
Compatibility with JEDEC standards
— Pinout and software compatible with single-power
supply Flash standard
■
Package options
— 48-pin TSOP and Reverse TSOP (LV641GH/L only)
— 63-ball Fine-Pitch BGA (LV640GU only)
— 64-ball Fortified BGA (LV640GU only)
■
Minimum 1 million erase cycle guarantee per sector
■
20-year data retention at 125
°
C
PERFORMANCE CHARCTERISTICS
■
High performance
— Access time ratings as fast as 55 ns
■
Ultra low power consumption (typical values at 3.0 V,
5 MHz)
— 9 mA typical active read current
— 26 mA typical erase/program current
— 200 nA typical standby mode current
■
Program and erase performance (V
HH
not applied to
the ACC input pin)
— Word program time: 7 μs typical
— Sector erase time: 0.6 s typical for each 32 Kword
sector
SOFTWARE AND HARDWARE FEATURES
■
Hardware features
—
Hardware reset input (RESET#):
resets device for
new operation
—
WP# input:
protects first or last 32 Kword sector
regardless of sector protection settings
(LV641GH/L only)
—
ACC input:
Accelerates programming time for higher
throughput during system production
■
Software features
—
Program Suspend & Resume:
read other sectors
before programming operation is completed
—
Sector Group Protection:
V
CC
-level method of
preventing program or erase operations within a
sector
—
Temporary Sector Group Unprotect:
V
ID
-level method
of changing in previously locked sectors
—
CFI (Common Flash Interface) compliant:
allows host
system to identify and accommodate multiple flash
devices
—
Erase Suspend/Erase Resume:
read/program other
sectors before an erase operation is complete
—
Data# Polling
and
toggle bits
provide erase and
programming operation status
—
Unlock Bypass Program
command reduces overall
multiple-word programming time
