Data Sheet
July 2003
The following document specifies Spansion memory products that are now offered by both Advanced
Micro Devices and Fujitsu. Although the document is marked with the name of the company that orig-
inally developed the specification, these products will be offered to customers of both AMD and
Fujitsu.
Continuity of Specifications
There is no change to this datasheet as a result of offering the device as a Spansion product. Any
changes that have been made are the result of normal datasheet improvement and are noted in the
document revision summary, where supported. Future routine revisions will occur when appropriate,
and changes will be noted in a revision summary.
Continuity of Ordering Part Numbers
AMD and Fujitsu continue to support existing part numbers beginning with “Am” and “MBM”. To order
these products, please use only the Ordering Part Numbers listed in this document.
For More Information
Please contact your local AMD or Fujitsu sales office for additional information about Spansion
memory solutions.

PRELIMINARY
Am29LV642D
128 Megabit (8 M x 16-Bit) CMOS 3.0 Volt-only
Uniform Sector Flash Memory with VersatileI/O Control
DISTINCTIVE CHARACTERISTICS
s Two 64 Megabit (Am29LV640D) in a single 64-ball 13
x 11 mm Fortified BGA package (Note: Features will
be described for each internal Am29LV640D)
s Two Chip Enable pins
— Two CE# pins to control selection of each internal
Am29LV640D devices
s Single power supply operation
— 3.0 to 3.6 volt read, erase, and program operations
s VersatileI/O control
— Device generates data output voltages and tolerates
data input voltages as determined by the voltage on
the VIO pin
s High performance
— Access times as fast as 90 ns
s Manufactured on 0.23 µm process technology
s CFI (Common Flash Interface) compliant
— Provides device-specific information to the system,
allowing host software to easily reconfigure for
different Flash devices
s Ultra low power consumption (typical values at 3.0 V,
5 MHz) for the part
— 9 mA typical active read current
— 26 mA typical erase/program current
— 400 nA typical standby mode current
s Flexible sector architecture
— Two hundred fifty-six 32 Kword sectors
s Sector Protection
— A hardware method to lock a sector to prevent
program or erase operations within that sector
— Sectors can be locked in-system or via programming
equipment
— Temporary Sector Unprotect feature allows code
changes in previously locked sectors
s Embedded Algorithms
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically writes
and verifies data at specified addresses
s Compatibility with JEDEC standards
— Except for the additional CE2# pin, the Fortified BGA
is pinout and software compatible with single-power
supply Flash
— Superior inadvertent write protection
s Minimum 1 million erase cycle guarantee per sector
s 64-ball Fortified BGA Package
s Erase Suspend/Erase Resume
— Suspends an erase operation to read data from, or
program data to, a sector that is not being erased,
then resumes the erase operation
s Data# Polling and toggle bits
— Provides a software method of detecting program or
erase operation completion
s Unlock Bypass Program command
— Reduces overall programming time when issuing
multiple program command sequences
s Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting program or
erase cycle completion
s Hardware reset pin (RESET#)
— Hardware method to reset the device for reading array
data
s ACC pin
— Accelerates programming time for higher throughput
during system production
s Program and Erase Performance (VHH not applied to
the ACC input pin)
— Word program time: 11 µs typical
— Sector erase time: 1.6 s typical for each 32 Kword
sector
s 20-year data retention at 125°C
— Reliable operation for the life of the system
