Advanced Micro Devices 

Am29LV001B

1 Megabit (128 K x 8-Bit)

CMOS 3.0 Volt-only Boot Sector Flash Memory

DISTINCTIVE CHARACTERISTICS

■ Single power supply operation

— Full voltage range: 2.7 to 3.6 volt read and write

operations for battery-powered applications

— Regulated voltage range: 3.0 to 3.6 volt read and

write operations and for compatibility with high

performance 3.3 volt microprocessors

■ Manufactured on 0.32 µm process technology

■ High performance

— Full voltage range: access times as fast as 55 ns

— Regulated voltage range: access times as fast as

45 ns

■ Ultra low power consumption (typical values at 5

MHz)

— 200 nA Automatic Sleep mode current

— 200 nA standby mode current

— 7 mA read current

— 15 mA program/erase current

■ Flexible sector architecture

— One 8 Kbyte, two 4 Kbyte, and seven 16 Kbyte

— Supports full chip erase

— Sector Protection features:

Hardware method of locking a sector to prevent any

program or erase operations within that sector

Sectors can be locked in-system or via

programming equipment

Temporary Sector Unprotect feature allows code

changes in previously locked sectors

■ Unlock Bypass Mode Program Command

— Reduces overall programming time when issuing

multiple program command sequences

■ Top or bottom boot block configurations

available

■ Embedded Algorithms

— Embedded Erase algorithm automatically

preprograms and erases the entire chip or any

combination of designated sectors

— Embedded Program algorithm automatically

writes and verifies data at specified addresses

■ Minimum 1 million erase cycle guarantee per

sector

■ 20 Year data retention at 125°C

— Reliable operation for the life of the system

■ Package option

— 32-pin TSOP

— 32-pin PLCC

■ Compatibility with JEDEC standards

— Pinout and software compatible with single-

power supply Flash

— Superior inadvertent write protection

■ Data# Polling and toggle bits

— Provides a software method of detecting program

or erase operation completion

■ Erase Suspend/Erase Resume

— Supports reading data from or programming data

to a sector that is not being erased

■ Hardware reset pin (RESET#)

— Hardware method for resetting the device to

reading array data
