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

■ 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

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

preventing program or erase operations within a

sector

— Temporary Sector Group Unprotect: V

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
