ADVANCE INFORMATION
Am29DL322C/Am29DL323C
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
s Simultaneous Read/Write operations
â Data can be continuously read from one bank while
executing erase/program functions in other bank.
â Zero latency between read and write operations
s Multiple bank architectures
â Two devices available with different bank sizes (refer
to Table 3)
s SecSi (Secured Silicon) Sector: Extra 64 KByte
sector
â 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
â Customer lockable: Can be read, programmed, or
erased just like other sectors. Once locked, data
cannot be changed
s Zero Power Operation
â Sophisticated power management circuits reduce
power consumed during inactive periods to nearly
zero.
s Package options
â 63-ball FBGA
â 56-pin SSOP
â 48-pin TSOP
s Top or bottom boot block
s Manufactured on 0.32 µm process technology
s Compatible with JEDEC standards
â Pinout and software compatible with
single-power-supply flash standard
PERFORMANCE CHARACTERISTICS
s High performance
â Access time as fast 90 ns
â Program time: 7 µs/word typical utilizing Accelerate
function
s Ultra low power consumption (typical values)
â 2 mA active read current at 1 MHz
â 10 mA active read current at 5 MHz
â 200 nA in standby or automatic sleep mode
s Minimum 1 million write cycles guaranteed per
sector
s 20 year data retention at 125°C
â Reliable operation for the life of the system
SOFTWARE FEATURES
s Data Management Software (DMS)
â AMD-supplied software manages data programming,
enabling EEPROM emulation
â Eases historical sector erase flash limitations
s Supports Common Flash Memory Interface (CFI)
s Erase Suspend/Erase Resume
â Suspends erase operations to allow programming in
same bank
s Data# Polling and Toggle Bits
â Provides a software method of detecting the status of
program or erase cycles
s Unlock Bypass Program command
â Reduces overall programming time when issuing
multiple program command sequences
HARDWARE FEATURES
s Any combination of sectors can be erased
s Ready/Busy# output (RY/BY#)
â Hardware method for detecting program or erase
cycle completion
s Hardware reset pin (RESET#)
â Hardware method of resetting the internal state
machine to the read mode
s WP#/ACC input pin
â Write protect (WP#) function allows protection of two
outermost boot sectors, regardless of sector protect
status
â Acceleration (ACC) function provides accelerated
program times
s Sector protection
â Hardware method of locking a sector, either
in-system or using programming equipment, to
prevent any program or erase operation within that
sector
â Temporary Sector Unprotect allows changing data in
protected sectors in-system
