PRELIMINARY
Am29LV002
2 Megabit (256 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 High performance
— Full voltage range: access times as fast as 100
ns
— Regulated voltage range: access times as fast
as 90 ns
s Ultra low power consumption (typical values at
5 MHz)
— Automatic Sleep Mode: 200 nA
— Standby mode: 200 nA
— Read mode: 10 mA
— Program/erase mode: 20 mA
s Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors
— Supports control code and data storage on a
single device
— Sector Protection features:
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
s Top or bottom boot block configurations
available
s Embedded Algorithms
— Embedded Erase algorithms automatically
preprogram and erase the entire chip or any
combination of designated sectors
— Embedded Program algorithms automatically
write and verify bytes or words at specified
addresses
s Typical 1,000,000 write cycles per sector
(100,000 cycles minimum guaranteed)
s Package option
— 40-pin TSOP
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 Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
s Erase Suspend/Erase Resume feature
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
s Hardware reset pin (RESET#)
— Hardware method to reset the device to the read
mode
