Am29LV008B
8 Megabit (1 M x 8-Bit)
CMOS 3.0 Volt-only Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
■ Top or bottom boot block configurations
available
— Full voltage range: 2.7 to 3.6 volt read and write
operations for battery-powered applications
■ Embedded Algorithms
— Regulated voltage range: 3.0 to 3.6 volt read and
write operations and for compatibility with high
performance 3.3 volt microprocessors
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
■ Manufactured on 0.32 µm process technology
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
— Compatible with 0.5 µm Am29LV008 device
■ Minimum 1,000,000 write cycle guarantee per sector
■ 20-year data retention at 125°C
— Reliable operation for the life of the system
■ Package option
■ High performance
— Full voltage range: access times as fast as 80 ns
— Regulated voltage range: access times as fast as
70 ns
— 40-pin TSOP
■ Ultra low power consumption (typical values at 5
MHz)
■ Compatibility with JEDEC standards
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 7 mA read current
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
— 15 mA program/erase current
■ Data# Polling and toggle bits
■ Flexible sector architecture
— Provides a software method of detecting program
or erase operation completion
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
fifteen 64 Kbyte sectors
■ Ready/Busy# pin (RY/BY#)
— Supports full chip erase
— Provides a hardware method of detecting
program or erase cycle completion
— Sector Protection features:
A hardware method of locking a sector to prevent
any program or erase operations within that
sector
■ Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
Sectors can be locked in-system or via
programming equipment
■ Hardware reset pin (RESET#)
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
— Hardware method to reset the device to reading
array data
■ Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
