SUPPLEMENT
Am29BL802C Known Good Die
8 Megabit (512 K x 16-Bit)
CMOS 3.0 Volt-only, Burst-mode, Boot Sector Flash Memory—Die Revision 1
DISTINCTIVE CHARACTERISTICS
s
32 words sequential with wrap around (linear
32), bottom boot
s
One 8 Kword, two 4 Kword, one 48 Kword, three
64 Kword, and two 128 Kword sectors
s
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
s
Read access times
22 ns burst access at
extended temperature range
80 ns initial/random access
s
Alterable burst length via BAA# pin
s
Power dissipation (typical)
— Burst Mode Read: 15 mA @ 25 MHz,
20 mA @ 33 MHz, 25 mA @ 40 MHz
— Program/Erase: 20 mA
— Standby mode, CMOS: 22 µA
s
5 V-tolerant data, address, and control signals
s
Sector Protection
— Implemented using in-system or via
programming equipment
— Temporary Sector Unprotect feature allows code
changes in previously locked sectors
s
Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
s
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
s
Minimum 100,000 erase cycle guarantee
per sector
s
20-year data retention at 125°C
s
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
— Backward-compatible with AMD Am29LV and
Am29F flash memories: powers up in
asynchronous mode for system boot, but can
immediately be placed into burst mode
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
— 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 for reading
array data
s
Tested to datasheet specifications at
temperature
s
Quality and reliability levels equivalent to
standard packaged components
