ADVANCE INFORMATION
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
— 4-word/8-byte page read buffer
— 16-word/32-byte write buffer
■ Single power supply operation
— 3 V for read, erase, and program operations
■ Low power consumption (typical values at 3.0 V, 5
MHz)
■ VersatileI/O control
— 30 mA typical active read current
— 50 mA typical erase/program current
— 1 µA typical standby mode current
— Device generates data output voltages and tolerates
data input voltages on the DQ inputs/outputs as
determined by the voltage on the VIO pin; operates
from 1.65 to 3.6 V
■ Package options
— 56-pin TSOP
■ Manufactured on 0.23 µm MirrorBit process
technology
— 64-ball Fortified BGA
■ SecSi (Secured Silicon) Sector region
SOFTWARE & HARDWARE FEATURES
— 128-word/256-byte sector for permanent, secure
identification through an 8-word/16-byte random
Electronic Serial Number, accessible through a
command sequence
■ Software features
— Program Suspend & Resume: read other sectors
before programming operation is completed
— May be programmed and locked at the factory or by
— Erase Suspend & Resume: read/program other
the customer
sectors before an erase operation is completed
— Data# polling & toggle bits provide status
■ Flexible sector architecture
— Unlock Bypass Program command reduces overall
— One hundred twenty-eight 32 Kword/64-Kbyte sectors
multiple-word programming time
■ Compatibility with JEDEC standards
— CFI (Common Flash Interface) compliant: allows host
system to identify and accommodate multiple flash
devices
— Provides pinout and software compatibility for
single-power supply flash, and superior inadvertent
write protection
■ Hardware features
■ Minimum 100,000 erase cycle guarantee per sector
■ 20-year data retention at 125°C
— Sector Group Protection: hardware-level method of
preventing write operations within a sector group
— Temporary Sector Unprotect: VID-level method of
PERFORMANCE CHARACTERISTICS
■ High performance
changing code in locked sectors
— ACC (high voltage) input accelerates programming
— 90 ns access time
time for higher throughput during system production
— 25 ns page read times
— Hardware reset input (RESET#) resets device
— 0.4 s typical sector erase time
— Ready/Busy# output (RY/BY#) indicates program or
— 5.9 µs typical write buffer word programming time:
16-word/32-byte write buffer reduces overall
erase cycle completion
programming time for multiple-word/byte updates
