Am29LV040B  
4 Megabit (512 K x 8-Bit)  
CMOS 3.0 Volt-only, Uniform Sector 32-Pin Flash Memory  
DISTINCTIVE CHARACTERISTICS  
Single power supply operation  
Unlock Bypass Program Command  
— Full voltage range: 2.7 to 3.6 volt read and write  
operations for battery-powered applications  
— Reduces overall programming time when issuing  
multiple program command sequences  
— Regulated voltage range: 3.0 to 3.6 volt read and  
write operations and for compatibility with high  
performance 3.3 volt microprocessors  
Embedded Algorithms  
— Embedded Erase algorithms automatically  
preprogram and erase the entire chip or any  
combination of designated sectors  
Manufactured on 0.32 µm process technology  
High performance  
— Embedded Program algorithms automatically  
writes and verifies data at specified addresses  
— Full voltage range: access times as fast as 70 ns  
— Regulated voltage range: access times as fast as  
60 ns  
Minimum 1,000,000 write/erase cycles  
guaranteed  
20-year data retention at 125°C  
— Reliable operation for the life of the system  
Package option  
Ultra low power consumption (typical values at  
5 MHz)  
— Automatic sleep mode: 1 µA  
— Standby mode: 1 µA  
— 32-pin PLCC  
— Read mode: 7 mA  
— 32-pin TSOP  
— Program/erase mode: 15 mA  
Compatibility with JEDEC standards  
— Pinout and software compatible with single-  
power supply Flash  
Flexible sector architecture  
— Eight 64 Kbyte sectors  
— Superior inadvertent write protection  
— Any combination of sectors can be erased;  
supports full chip erase  
Data# Polling and toggle bits  
— Sector Protection features:  
— Provides a software method of detecting program  
or erase cycle completion  
Hardware method of locking a sector to prevent  
any program or erase operations within that sector  
Erase Suspend/Resume  
Sectors can be locked via programming  
equipment  
— Supports reading data from or programming data  
to a sector not being erased
