Am29LV640MH/L

64 Megabit (4 M x 16-Bit/8 M x 8-Bit) MirrorBit

™

3.0 Volt-only Uniform Sector Flash Memory

with VersatileI/O

™ Control

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

Single power supply operation

— 3 V for read, erase, and program operations

VersatileI/O

™ control

— Device generates data output voltages and tolerates

data input voltages on the DQ inputs/outputs as

determined by the voltage on the V

from 1.65 to 3.6 V

Manufactured on 0.23 µm MirrorBit process

technology

SecSi

™ (Secured Silicon) Sector region

— 128-word/256-byte sector for permanent, secure

identification through an 8-word/16-byte random

Electronic Serial Number, accessible through a

command sequence

— May be programmed and locked at the factory or by

the customer

Flexible sector architecture

— One hundred twenty-eight 32 Kword/64-Kbyte sectors

Compatibility with JEDEC standards

— Provides pinout and software compatibility for

single-power supply flash, and superior inadvertent

write protection

Minimum 100,000 erase cycle guarantee per sector

20-year data retention at 125

°C

PERFORMANCE CHARACTERISTICS

High performance

— 90 ns access time

— 25 ns page read times

— 0.5 s typical sector erase time

— 22 µs typical effective write buffer word programming

time: 16-word/32-byte write buffer reduces overall

programming time for multiple-word/byte updates

— 4-word/8-byte page read buffer

— 16-word/32-byte write buffer

Low power consumption (typical values at 3.0 V, 5

MHz)

— 30 mA typical active read current

— 50 mA typical erase/program current

— 1 µA typical standby mode current

Package options

— 56-pin TSOP

— 64-ball Fortified BGA

SOFTWARE FEATURES

— Program Suspend & Resume: read other sectors

before programming operation is completed

— Erase Suspend & Resume: read/program other

sectors before an erase operation is completed

— Data# polling & toggle bits provide status

— Unlock Bypass Program command reduces overall

multiple-word programming time

— CFI (Common Flash Interface) compliant: allows host

system to identify and accommodate multiple flash

devices

HARDWARE FEATURES

— Sector Group Protection: hardware-level method of

preventing write operations within a sector group

— Temporary Sector Unprotect: V

changing code in locked sectors

— WP#/ACC input:

Write Protect input (WP#) protects first or last sector

regardless of sector protection settings

ACC (high voltage) accelerates programming time for

higher throughput during system production

— Hardware reset input (RESET#) resets device

— Ready/Busy# output (RY/BY#) indicates program or

erase cycle completion
