DATA SHEET
Am29DL32xG
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
■
 Simultaneous Read/Write operations
— Data can be continuously read from one bank while 
executing erase/program functions in other bank
— Zero latency between read and write operations
■
 Multiple bank architectures
— Three devices available with different bank sizes (refer 
to Table 3)
■
 256-byte Secured Silicon Sector
—
 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
—
 Customer lockable:
 One time programmable. Once 
locked, data cannot be changed.
■
 Zero Power Operation
— Sophisticated power management circuits reduce 
power consumed during inactive periods to nearly 
zero
■
 Package options
— 63-ball FBGA
— 48-ball FBGA
— 48-pin TSOP
— 64-ball Fortified BGA
■
 Top or bottom boot block 
■
 Manufactured on 0.17 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 70 ns 
— Program time: 4 μs/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
■
 Data Management Software (DMS)
— AMD-supplied software manages data programming, 
enabling EEPROM emulation
— Eases historical sector erase flash limitations
■
 Supports Common Flash Memory Interface (CFI)
■
 Erase Suspend/Erase Resume
— Suspends erase operations to allow programming in 
same bank
■
 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 accelerates program 
timing
■
 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
