PRELIMINARY
Am29LV001B
1 Megabit (128 K x 8-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
s 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
s Manufactured on 0.35 µm process technology
s High performance
— Full voltage range: access times as fast as 55 ns
— Regulated voltage range: access times as fast
as 45 ns
s 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
s 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
s Unlock Bypass Mode Program Command
— Reduces overall programming time when
issuing multiple program command sequences
s Top or bottom boot block configurations
available
s 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
s Minimum 1,000,000 write cycle guarantee per
sector
s Package option
— 32-pin TSOP
— 32-pin PLCC
s Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
s Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
s Erase Suspend/Erase Resume
— Supports reading data from or programming
data to a sector that is not being erased
s Hardware reset pin (RESET#)
— Hardware method for resetting the device to
reading array data
