DATA SHEET
Am29LV400B
4 Megabit (512 K x 8-Bit/256 K x 16-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 for compatibility with high
performance 3.3 volt microprocessors
■ Manufactured on 0.32 µm process technology
— Compatible with 0.5 µm Am29LV400 device
■ High performance
— Full voltage range: access times as fast as 70 ns
— Regulated voltage range: access times as fast as
55 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 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
seven 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
seven 32 Kword sectors (word mode)
— Supports full chip erase
— Sector Protection features:
— A 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 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 1,000,000 write cycle guarantee per sector
■ 20-year data retention at 125°C
— Reliable operation for the life of the system
■ Package option
— 48-ball FBGA
— 48-pin TSOP
— 44-pin SO
— Lead (Pb) - Free Packaging Available
■ 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
■ Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
■ 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
■ Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
