Am29LV6402M

128 Megabit (4 M x 32-Bit/8 M x 16-Bit)

MirrorBit

™ 3.0 Volt-only

Uniform Sector Flash Memory with Versatile I/O™ Control

DISTINCTIVE CHARACTERISTICS

ARCHITECTURAL ADVANTAGES

■ Single power supply operation

— 3 volt read, erase, and program operations

— Device generates data output voltages and tolerates

data input voltages on the CE# and DQ inputs/outputs

from 1.65 to 3.6 V

technology

■ SecSi™ (Secured Silicon) Sector region

— 128-doubleword/256-word sector for permanent,

secure identification through an

8-doubleword/16-word 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 Kdoubleword (64

Kword) sectors

■ Compatibility with JEDEC standards

— Provides pinout and software compatibility for

single-power supply flash, and superior inadvertent

write protection

■ 100,000 erase cycles per sector

■ 20-year data retention at 125°C

PERFORMANCE CHARACTERISTICS

■ High performance

— 100 ns access time

— 30 ns page read times

— 0.5 s typical sector erase time

— 22 µs typical write buffer doubleword programming

time: 16-doubleword/32-word write buffer reduces

overall programming time for multiple-word updates

— 4-doubleword/8-word page read buffer

— 16-doubleword/32-word write buffer

■ Low power consumption (typical values at 3.0 V, 5

MHz)

— 26 mA typical active read current

— 100 mA typical erase/program current

— 2 µA typical standby mode current

■ Package options

— 80-ball Fortified BGA

SOFTWARE & HARDWARE FEATURES

■ 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 or byte 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 accelerates programming time

(when high voltage 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
