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.

Am29LV320D
32 Megabit (4 M x 8-Bit/2 M x 16-Bit)
CMOS 3.0 Volt-only, Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
Secured Silicon (SecSiTM Sector)
— 64 Kbyte Sector Size; Replacement/substitute
devices (such as Mirrorbit) have 256 bytes.
Factory locked and identifiable: 16 bytes (8
words) available for secure, random factory
Electronic Serial Number; verifiable as factory
locked through autoselect function.
ExpressFlash option allows entire sector to be
available for factory-secured data
Customer lockable: Can be programmed once
and then permanently locked after being
shipped from AMD
Zero Power Operation
— Sophisticated power management circuits
reduce power consumed during inactive
periods to nearly zero.
Package options
— 48-pin TSOP
— 48-ball FBGA
Sector Architecture
— Eight 8 Kbyte sectors
— Sixty-three 64 Kbyte sectors
Top or bottom boot block
Manufactured on 0.23 µm process
technology
Compatible with JEDEC standards
— Pinout and software compatible with
single-power-supply flash standard
PERFORMANCE CHARACTERISTICS
High performance
— Access time as fast 90 ns
— Program time: 7µs/word typical utilizing
Accelerate function
Ultra low power consumption (typical
values)
— 2 mA active read current at 1 MHz
— 10 mA active read current at 5 MHz
— 200 nA in standby or automatic sleep mode
Minimum 1 million erase cycles guaranteed
per sector
20 Year data retention at 125°C
— Reliable operation for the life of the system
SOFTWARE FEATURES
Supports Common Flash Memory Interface
(CFI)
Erase Suspend/Erase Resume
— Suspends erase operations to allow
programming in non-suspended sectors
Data# Polling and Toggle Bits
— Provides a software method of detecting the
status of program or erase cycles
Unlock Bypass Program command
— Reduces overall programming time when
issuing multiple program command sequences
HARDWARE FEATURES
Any combination of sectors can be erased
Ready/Busy# output (RY/BY#)
— Hardware method for detecting program or
erase cycle completion
Hardware reset pin (RESET#)
— Hardware method of resetting the internal
state machine to the read mode
WP#/ACC input pin
— Write protect (WP#) function allows protection
of two outermost boot sectors, regardless of
sector protect status
— Acceleration (ACC) function provides
accelerated program times
Sector protection
— Hardware method of locking a sector, either
in-system or using programming equipment,
to prevent any program or erase operation
within that sector
— Temporary Sector Unprotect allows changing
data in protected sectors in-system
