Am29BL162C
16 Megabit (1 M x 16-Bit) CMOS 3.0 Volt-only Burst Mode Flash Memory
DISTINCTIVE CHARACTERISTICS
32 words sequential with wrap around
20-year data retention
(linear 32), bottom boot
CFI (Common Flash Interface) compliant
One 8 Kword, two 4 Kword, one 112 Kword, and
— Provides device-specific information to the
system, allowing host software to easily
reconfigure for different Flash devices
seven 128 Kword sectors
Single power supply operation
— Regulated voltage range: 3.0 to 3.6 volt read and
write operations and for compatibility with high
performance 3.3 volt microprocessors
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
Read access times
— Superior inadvertent write protection
Burst access times as fast as 17 ns at industrial
temperature range (18 ns at extended
temperature range)
— Backward-compatible with AMD Am29LVxxx
and Am29Fxxx flash memories: powers up in
asynchronous mode for system boot, but can
immediately be placed into burst mode
Initial/random access times as fast as 65 ns
Alterable burst length via BAA# pin
Power dissipation (typical)
Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
— Burst Mode Read: 15 mA @ 25 MHz,
20 mA @ 33 MHz, 25 mA @ 40 MHz
Ready/Busy# pin (RY/BY#)
— Program/Erase: 20 mA
— Provides a hardware method of detecting
program or erase cycle completion
— Standby mode, CMOS: 3 µA
5 V-tolerant data, address, and control signals
Sector Protection
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
— Implemented using 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 for reading
array data
Unlock Bypass Program Command
— Reduces overall programming time when
issuing multiple program command sequences
Package Option
— 56-pin SSOP
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 erase cycle guarantee
per sector
