32 Megabit (4 M x 8-Bit/2 M x 16-Bit)
CMOS 3.0 Volt-only, Boot Sector Flash Memory
This product has been retired and is not available for designs. For new and current designs, S29AL032D supersedes Am29LV320D and is the factory-recommended migration path. Please
refer to the S29AL032D datasheet for specifications and ordering information. Availability of this document is retained for reference and historical purposes only.
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
Minimum 1 million erase cycles guaranteed per
sector
Secured Silicon
20 Year data retention at 125°C
— 64 Kbyte Sector Size; Replacement/substitute
— Reliable operation for the life of the system
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
SOFTWARE FEATURES
Supports Common Flash Memory Interface (CFI)
Erase Suspend/Erase Resume
autoselect function. ExpressFlash option allows
entire sector to be available for factory-secured data
— Suspends erase operations to allow programming in
non-suspended sectors
— Customer lockable: Can be programmed once and
then permanently locked after being shipped from
AMD
Data# Polling and Toggle Bits
— Provides a software method of detecting the status of
program or erase cycles
Zero Power Operation
Unlock Bypass Program command
— Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero.
— Reduces overall programming time when issuing
multiple program command sequences
Package options
— 48-pin TSOP
— 48-ball FBGA
HARDWARE FEATURES
Any combination of sectors can be erased
Ready/Busy# output (RY/BY#)
Sector Architecture
— Hardware method for detecting program or erase
cycle completion
— Eight 8 Kbyte sectors
— Sixty-three 64 Kbyte sectors
Top or bottom boot block
Hardware reset pin (RESET#)
— Hardware method of resetting the internal state
machine to the read mode
Manufactured on 0.23 µm process technology
Compatible with JEDEC standards
WP#/ACC input pin
— Pinout and software compatible with
single-power-supply flash standard
— Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect
status
PERFORMANCE CHARACTERISTICS
— Acceleration (ACC) function provides accelerated
program times
High performance
— Access time as fast 90 ns
Sector protection
— Program time: 7µs/word typical utilizing Accelerate
function
— Hardware method of locking a sector, either
in-system or using programming equipment, to
prevent any program or erase operation within that
sector
Ultra low power consumption (typical values)
— 2 mA active read current at 1 MHz
— Temporary Sector Unprotect allows changing data in
protected sectors in-system
— 10 mA active read current at 5 MHz
— 200 nA in standby or automatic sleep mode
