Am29LV256M
256 Megabit (16 M x 16-Bit/32 M x 8-Bit) MirrorBit
TM 3.0 Volt-only
Uniform Sector Flash Memory with VersatileI/O
TM Control
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
Single power supply operation
— 3 volt read, erase, and program operations
VersatileI/O
TM control
— Device generates data output voltages and tolerates
data input voltages on the CE# and DQ inputs/outputs
as determined by the voltage on the V
IO pin; operates
from 1.65 to 3.6 V
Manufactured on 0.23 µm MirrorBit process
technology
SecSi
TM (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
— Five hundred twelve 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
— 100 ns access time
— 30 ns page read times
— 0.5 s typical sector erase time
— 15 µs typical effective write buffer word programming
time: 16-word/32-byte write buffer reduces overall
programming time for multiple-word 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)
— 13 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 & 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 Group Unprotect: V
ID-level method
of changing code in locked sector groups
— 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
