Am29LV160BT/Am29LV160BB
16 Megabit (2 M x 8-Bit/1 M x 16-Bit)
CMOS 3.0 Volt-only Sector Erase 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 0.35 µm process technology
Supports Common Flash Memory Interface
(CFI)
High performance
— Full voltage range: access times as fast as 90 ns
— Regulated voltage range: access times as fast
as 80 ns
Ultra low power consumption (typical values at
5 MHz)
— 200 nA Automatic Sleep mode current
— 200 nA standby mode current
— 10 mA read current
— 20 mA program/erase current
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
thirty-one 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
thirty-one 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
Circuit Descriptions and List of Abbreviations
SACD 900
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 100,000 write cycle guarantee per
sector
Package option
— 48-ball FBGA
— 48-ball µBGA
— 48-pin TSOP
— 44-pin SO
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 (not
available on 44-pin SO)
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
