Am29DL322D/323D/324D
32 Megabit (4 M x 8-Bit/2 M x 16-Bit)
CMOS 3.0 Volt-only, Simultaneous Operation Flash Memory
DISTINCTIVE CHARACTERISTICS
ARCHITECTURAL ADVANTAGES
โ–  Simultaneous Read/Write operations
โ€” Data can be continuously read from one bank while
executing erase/program functions in other bank.
โ€” Zero latency between read and write operations
โ–  Multiple bank architectures
โ€” Three devices available with different bank sizes
(refer to Table 3)
โ–  SecSiTM (Secured Silicon) Sector
โ€” Current version of device has 64 Kbytes; future
versions will have 256 bytes
โ€” Factory locked and identifiable: 16 bytes 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
โ€” Customer lockable: Can be read, programmed, or
erased just like other sectors. Once locked, data
cannot be changed
โ–  Zero Power Operation
โ€” Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero.
โ–  Package options
โ€”63-ball FBGA
โ€” 48-pin TSOP
โ–  Top or bottom boot block
โ–  Manufactured on 0.23 ยตm process technology
โ–  Compatible with JEDEC standards
โ€” Pinout and software compatible with
single-power-supply flash standard
PERFORMANCE CHARACTERISTICS
โ–  High performance
โ€” Access time as fast 70 ns
โ€” Program time: 7 ยตs/word typical utilizing Accelerate
function
โ–  Ultra low power consumption (typical values)
โ€” 2 mA active read current at 1 MHz
โ€” 10 mA active read current at 5 MHz
โ€” 200 nA in standby or automatic sleep mode
โ–  Minimum 1 million write cycles guaranteed per
sector
โ–  20 year data retention at 125ยฐC
โ€” Reliable operation for the life of the system
SOFTWARE FEATURES
โ–  Data Management Software (DMS)
โ€” AMD-supplied software manages data programming,
enabling EEPROM emulation
โ€” Eases historical sector erase flash limitations
โ–  Supports Common Flash Memory Interface (CFI)
โ–  Erase Suspend/Erase Resume
โ€” Suspends erase operations to allow programming in
same bank
โ–  Data# Polling and Toggle Bits
โ€” Provides a software method of detecting the status of
program or erase cycles
โ–  Unlock Bypass Program command
โ€” Reduces overall programming time when issuing
multiple program command sequences
HARDWARE FEATURES
โ–  Any combination of sectors can be erased
โ–  Ready/Busy# output (RY/BY#)
โ€” Hardware method for detecting program or erase
cycle completion
โ–  Hardware reset pin (RESET#)
โ€” Hardware method of resetting the internal state
machine to the read mode
โ–  WP#/ACC input pin
โ€” Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect
status
โ€” Acceleration (ACC) function accelerates program
timing
โ–  Sector protection
โ€” Hardware method of locking a sector, either
in-system or using programming equipment, to
prevent any program or erase operation within that
sector
โ€” Temporary Sector Unprotect allows changing data in
protected sectors in-system
This product has been retired and is not available for designs. For new and current designs involving TSOP packages, S29JL032H supersedes Am29DL32xD and is the factory-recom-
mended migration path. Please refer to the S29JL032H Datasheet for specifications and ordering information.
For new and current designs involving Fine-pitch BGA (FBGA) packages, S29PL032J supersedes Am29DL32xD and is the factory-recommended migration path. Please refer to the
S29PL032J Datasheet for specifications and ordering information. Availability of this document is retained for reference and historical purposes only.
