GENERAL DESCRIPTION
A82DL32x4T(U) Features
The A82DL32x4T(U) family consists of 32 megabit, 3.0 volt-
only flash memory devices, organized as 2,097,152 words of
16 bits each or 4,194,304 bytes of 8 bits each. Word mode
data appears on I/O0–I/O15; byte mode data appears on I/O0–
I/O7. The device is designed to be programmed in-system
with the standard 3.0 volt VCC supply, and can also be
programmed in standard EPROM programmers.
The device offers complete compatibility with the JEDEC
single-power-supply Flash command set standard.
Commands are written to the command register using
standard microprocessor write timings. Reading data out of
the device is similar to reading from other Flash or EPROM
devices.
The device is available with an access time of 70ns. The
devices are offered in 69-ball Fine-pitch BGA. Standard
The host system can detect whether a program or erase
operation is complete by using the device status bits:

After a program or erase cycle has been completed, the
device automatically returns to reading array data.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data
contents of other sectors. The device is fully erased when
shipped from the factory.

operations, and avoid bus contention issues.
The device requires only a single 3.0 volt power supply for
both read and write functions. Internally generated and
regulated voltages are provided for the program and erase
operations.
Hardware data protection measures include a low VCC
detector that automatically inhibits write operations during
power transitions. The hardware sector protection feature
disables both program and erase operations in any
combination of the sectors of memory. This can be achieved
Simultaneous Read/Write Operations with Zero
Latency
The Simultaneous Read/Write architecture provides
simultaneous operation by dividing the memory space into
two banks. The device can improve overall system
in-s y s t e m or via programming equipment.
The device offers two power-saving features. When
addresses have been stable for a specified amount of time,
the device enters the automatic sleep mode. The system
can also place the device into the standby mode. Power
consumption is greatly reduced in both modes.
performance by allowing a host system to program or erase
in one bank, then immediately and simultaneously read from
the other bank, with zero latency. This releases the system
from waiting for the completion of program or erase
operations.
The A82DL32x4T(U) devices uses multiple bank archi-
tectures to provide flexibility for different applications. Three
devices are available with these bank sizes:

DEVICE BUS OPERATIONS
This section describes the requirements and use of the
device bus operations, which are initiated through the
internal command register. The command register itself does
not occupy any addressable memory location. The register is
composed of latches that store the commands, along with
the address and data information needed to execute the
command. The contents of the register serve as inputs to the
internal state machine. The state machine outputs dictate the
function of the device. The appropriate device bus operations
table lists the inputs and control levels required, and the
resulting output. The following subsections describe each of
these operations in further detail.

Autoselect Functions
The internal state machine is set for reading array data upon
device power-up, or after a hardware reset. This ensures that
no spurious alteration of the memory content occurs during
the power transition. No command is necessary in this mode
to obtain array data. Standard microprocessor read cycles
that assert valid addresses on the device address inputs
produce valid data on the device data outputs. Each bank
remains enabled for read access until the command register
contents are altered.
See "Requirements for Reading Array Data" for more
information. Refer to the AC Read-Only Operations table for
timing specifications and to Figure 11 for the timing
waveform, lCC1_F in the DC Characteristics table represents
the active current specification for reading array data.
If the system writes the autoselect command sequence, the
device enters the autoselect mode. The system can then
read autoselect codes from the internal register (which is
separate from the memory array) on I/O7-I/O0. Standard read
cycle timings apply in this mode. Refer to the Autoselect
Mode and Autoselect Command Sequence sections for more
information.
Simultaneous Read/Write Operations with Zero
Latency
This device is capable of reading data from one bank of
memory while programming or erasing in the other bank of
memory. An erase operation may also be suspended to read
from or program to another location within the same bank
(except the sector being erased). Figure 18 shows how read
and write cycles may be initiated for simultaneous operation
with zero latency. ICC6_F and ICC7_F in the DC Characteristics
table represent the current specifications for read-while-pro-
gram and read-while-erase, respectively.
Writing Commands/Command Sequences
To write a command or command sequence (which includes
programming data to the device and erasing sectors of
memory), the system must drive

The device features an Unlock Bypass mode to facilitate
faster programming. Once a bank enters the Unlock Bypass

An erase operation can erase one sector, multiple sectors, or
the entire device. The Sector Address Tables 3-4 indicate the
address range that each sector occupies. The device
address space is divided into two banks: Bank 1 contains the
boot/parameter sectors, and Bank 2 contains the larger, code
sectors of uniform size. A “bank address” is the address bits
required to uniquely select a bank. Similarly, a “sector
address” is the address bits required to uniquely select a

Temporary Sector/Sector Block Unprotect
The hardware sector protection feature disables both
program and erase operations in any sector. The hardware
sector unprotection feature re-enables both program and
erase operations in previously protected sectors. Sector
protection and unprotection can be implemented via two
methods.
(Note: For the following discussion, the term “sector” applies
to both sectors and sector blocks. A sector block consists of
two or more adjacent sectors that are protected or
unprotected at the same time (see Tables 6 and 7).
This feature allows temporary unprotection of previously
protected sectors to change data in-system. The Sector
The primary method requires VID on the

Unprotect mode is activated by setting the
pin to VID
RESET
and can be implemented either in-system or via
programming equipment. Figure 2 shows the algorithms and
Figure 23 shows the timing diagram. This method uses
standard microprocessor bus cycle timing. For sector
unprotect, all unprotected sectors must first be protected
prior to the first sector unprotect write cycle.
The sector unprotect algorithm unprotects all sectors in
parallel. All previously protected sectors must be individually
re-protected. To change data in protected sectors efficiently,
the temporary sector unprotect function is available. See
“Temporary Sector/Sector Block Unprotect”.
(8.5V-12.5V). During this mode, formerly protected sectors
can be programmed or erased by selecting the sector
addresses. Once VID is removed from the
pin, all the
RESET
previously protected sectors are protected again. Figure 1
shows the algorithm, and Figure 22 shows the timing
diagrams, for this feature.
The alternate method for protection and unprotection is by
software temporary sector /sector block unprotect command.
See Figure 2 for Command Flow.
The device is shipped with all sectors unprotected.
It is possible to determine whether a sector is protected or
unprotected. See the Autoselect Mode section for details.
Write Protect (

The Write Protect function provides a hardware method of
protecting certain boot sectors without using VID. This
function is one of two provided by the
/ACC pin.

/ACC pin, the device
WP
disables program and erase functions in the two “outermost”
8 Kbyte boot sectors independently of whether those sectors
were protected or unprotected using the method described in
“Sector/Sector Block Protection and Unprotection”. The two
outermost 8 Kbyte boot sectors are the two sectors
containing the lowest addresses in a bottom-boot-configured
device, or the two sectors containing the highest addresses
in a top-boot-configured device.
If the system asserts VIH on the
/ACC pin, the device
WP
reverts to whether the two outermost 8 Kbyte boot sectors
were last set to be protected or unprotected. That is, sector
protection or unprotection for these two sectors depends on
whether they were last protected or unprotected using the
method described in “Sector/Sector Block Protection and
Unprotection”.
Note that the
/ACC pin must not be left floating or
WP
unconnected; inconsistent behavior of the device may result.

The Common Flash Interface (CFI) specification outlines

which allows specific vendor-specified software algorithms to
be used for entire families of devices. Software support can
then be device-independent, JEDEC ID-independent, and
forward- and backward-compatible for the specified flash
device families. Flash vendors can standardize their existing
interfaces for long-term compatibility.
This device enters the CFI Query mode when the system
writes the CFI Query command, 98h, to address 55h in word

ready to read array data. The system can read CFI

When VCC_F is less than VLKO, the device does not accept
any write cycles. This protects data during VCC_F power-up

program/erase circuits are disabled, and the device resets to
reading array data. Subsequent writes are ignored until
VCC_F is greater than VLKO. The system must provide the

COMMAND DEFINITIONS
Writing specific address and data commands or sequences
into the command register initiates device operations. Table
12 defines the valid register command sequences. Writing
incorrect address and data values or writing them in the
improper sequence may place the device in an unknown
state. A reset command is then required to return the device
to reading array data.
Autoselect Command Sequence
The autoselect command sequence allows the host system
to access the manufacturer and device codes, and determine
whether or not a sector is protected. Table 12 shows the
address and data requirements. This method is an
alternative to that shown in Table 5, which is intended for
PROM programmers and requires VID on address pin A9.
The autoselect command sequence may be written to an
address wit h in a bank that is either in t he read or erase-
suspend-read mode. The autoselect command may not be
written while the device is actively programming or erasing in
the other bank.
All addresses are latched on the falling edge of
or

, whichever happens later. All data is latched on the
CE_F
rising edge of
or
, whichever happens first. Refer
WE
CE_F
to the AC Characteristics section for timing diagrams.
Reading Array Data
The autoselect command sequence is initiated by first writing
two unlock cycles. This is followed by a third write cycle that
contains the bank address and the autoselect command. T he
bank then enter s the autoselect mode. The system may read
at any address within the same bank any number of times
without initiating another autoselect command sequence:
ꢀA read cycle at address (BA)XX00h (where BA is the bank
address) returns the manufacturer code.
The device is automatically set to reading array data after
device power-up. No commands are required to retrieve
data. The device is also ready to read array data after
completing an Embedded Program or Embedded Erase
algorithm.
After the device accepts an Erase Suspend command, the
corresponding bank enters the erase-suspend-read mode,
after which the system can read data from any non-erase-
suspended sector within the same bank. After completing a
programming operation in the Erase Suspend mode, the
system may once again read array data with the same
exception. See the Erase Suspend/Erase Resume
Commands section for more information.
ꢀA read cycle at address (BA)XX01h in word mode (or
(BA)XX02h in byte mode) returns the device code.
ꢀA read cycle to an address containing a sector address
(SA) within the same bank, and the address 02h on A7-A0
in word mode (or the address 04h on A6-A-1 in byte mode)
returns 01h if the sector is protected, or 00h if it is
unprotected. (Refer to Tables 3-4 for valid sector
addresses).
The system must write the reset command to return to
reading array data (or erase-suspend-read mode if the bank
was previously in Erase Suspend).
The system must issue the reset command to return a bank
to the read (or erase-suspend-read) mode if I/O5 goes high
during an active program or erase operation, or if the bank is
in the autoselect mode. See the next section, Reset
Command, for more information.
See also Requirements for Reading Array Data in the Device
Bus Operations section for more information. The Read-Only
Operations table provides the read parameters, and Figure
11 shows the timing diagram.
Byte/Word Program Command Sequence
The system may program the device by word or byte,
depending on the state of the
pin. Programming is

a four-bus-cycle operation. The program command sequence
is initiated by writing two unlock write cycles, followed by the
program set-up command. The program address and data
are written next, which in turn initiate the Embedded Program
algorithm. The system is not required to provide further
controls or timings. The device automatically provides
internally generated program pulses and verifies the
programmed cell margin. Table 12 shows the address and
data requirements for the byte program command sequence.
When the Embedded Program algorithm is complete, that
bank then returns to reading array data and addresses are
no longer latched. The system can determine the status of
Writing the reset command resets the banks to the read or

this command.
The reset command may be written between the sequence

to reading array data. Once erasure begins, however, the
device ignores reset commands until the operation is
complete.

programming begins. This resets the bank to which the
system was writing to reading array data. If the program
command sequence is written to a bank that is in the Erase
Suspend mode, writing the reset command returns that bank
to the erase-suspend-read mode. Once programming begins,
however, the device ignores reset commands until the
operation is complete.
The reset command may be written between the sequence
cycles in an autoselect command sequence. Once in the
autoselect mode, the reset command must be written to
return to reading array data. If a bank entered the autoselect
mode while in the Erase Suspend mode, writing the reset
command returns that bank to the erase-suspend-read mode.
If I/O5 goes high during a program or erase operation, writing
the reset command returns the banks to reading array data
Any commands written to the device during the Embedded
Program Algorithm are ignored. Note that a hardware reset
immediately terminates the program operation. The program
command sequence should be reinitiated once that bank has
returned to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across sector
boundaries. A bit cannot be programmed from “0” back to a
“1.” Attempting to do so may cause that bank to set I/O5 = 1,
or cause the I/O7 and I/O6 status bits to indicate the operation
was successful. However, a succeeding read will show that
the data is still “0.” Only erase operations can convert a “0” to
a “1.”

Unlock Bypass Command Sequence
The unlock bypass feature allows the system to program
bytes or words to a bank faster than using the standard
program command sequence. The unlock bypass command
sequence is initiated by first writing two unlock cycles. This is
followed by a third write cycle containing the unlock bypass
command, 20h. The device then enters the unlock bypass

A two-cycle unlock bypass program command
sequence is all that is required to program in this mode. The
first cycle in this sequence contains the unlock bypass pro-
gram command, A0h; the second cycle contains the program
address and data. Additional data is programmed in the
same manner. This mode dispenses with the initial two
unlock cycles required in the standard program command
sequence, resulting in faster total programming time. Table
12 shows the requirements for the command sequence.
During the unlock bypass mode, only the Unlock Bypass
Program and Unlock Bypass Reset commands are valid. To
exit the unlock bypass mode, the system must issue the two-
cycle unlock bypass reset command sequence. The device
then returns to reading array data.

Chip erase is a six bus cycle operation. The chip erase

cycles are then followed by the chip erase command, which

Refer to the Erase and Program Operations tables in the AC
Characteristics section for parameters, and Figure 17 section

Erase Suspend/Erase Resume Commands
The Erase Suspend command, B0h, allows the system to
interrupt a sector erase operation and then read data from, or
program data to, any sector not selected for erasure. This
command is valid only during the sector erase operation,
including the 50 µs time-out period during the sector erase
command sequence. The Erase Suspend command is
ignored if written during the chip erase operation or
Embedded Program algorithm.
Sector Erase Command Sequence
When the Erase Suspend command is written during the
sector erase operation, the device requires a maximum of 20
µs to suspend the erase operation. However, when the Erase
Suspend command is written during the sector erase time-
out, the device immediately terminates the time-out period
and suspends the erase operation.
After the erase operation has been suspended, the bank
enters the erase-suspend-read mode. The system can read
data from or program data to any sector not selected for
erasure. (The device “erase suspends” all sectors selected
for erasure.) Reading at any address within erase-suspended
sectors produces status information on I/O7–I/O0. The system
can use I/O7, or I/O6 and I/O2 together, to determine if a
sector is actively erasing or is erase-suspended. Refer to the
Write Operation Status section for information on these
status bits.
After an erase-suspended program operation is complete,
the bank returns to the erase-suspend-read mode. The
system can determine the status of the program operation
using the I/O7 or I/O6 status bits, just as in the standard Byte
Program operation. Refer to the Write Operation Status
section for more information.
In the erase-suspend-read mode, the system can also issue
the autoselect command sequence. Refer to the Autoselect
Mode and Autoselect Command Sequence sections for
details.
Sector erase is a six bus cycle operation. The sector erase
command sequence is initiated by writing two unlock cycles,
followed by a set-up command. Two additional unlock cycles
are written, and are then followed by the address of the
sector to be erased, and the sector erase command. Table
12 shows the address and data requirements for the sector
erase command sequence.
The device does not require the system to preprogram prior
to erase. The Embedded Erase algorithm automatically
programs and verifies the entire memory for an all zero data
pattern prior to electrical erase. The system is not required to
provide any controls or timings during these operations.
After the command sequence is written, a sector erase time-
out of 50 µs occurs. During the time-out period, additional
sector addresses and sector erase commands within the
bank may be written. Loading the sector erase buffer may be
done in any sequence, and the number of sectors may be
from one sector to all sectors. The time between these
additional cycles must be less than 50µs, otherwise erasure
may begin. Any sector erase address and command
following the exceeded time-out may or may not be accepted.
It is recommended that processor interrupts be disabled
during this time to ensure all commands are accepted. The
interrupts can be re-enabled after the last Sector Erase
command is written. Any command other than Sector Erase
or Erase Suspend during the time-out period resets that bank
to reading array data. The system must rewrite the command
sequence and any additional addresses and commands.
The system can monitor I/O3 to determine if the sector erase
timer has timed out (See the section on I/O3: Sector Erase
Timer.). The time-out begins from the rising edge of the final
To resume the sector erase operation, the system must write
the Erase Resume command. The bank address of the
erase-suspended bank is ignored when writing this command.
Further writes of the Resume command are ignored. Another

program or erase operation), and during the sector erase
time-out.
During an Embedded Program or Erase algorithm operation,
successive read cycles to any address cause I/O6 to toggle.

cycles. When the operation is complete, I/O6 stops toggling.
After an erase command sequence is written, if all sectors
selected for erasing are protected, I/O6 toggles for
approximately 100µs, then returns to reading array data. If not
all selected sectors are protected, the Embedded Erase
algorithm erases the unprotected sectors, and ignores the
selected sectors that are protected.
The system can use I/O6 and I/O2 together to determine
whether a sector is actively erasing or is erase-suspended.
When the device is actively erasing (that is, the Embedded
Erase algorithm is in progress), I/O6 toggles. When the device
enters the Erase Suspend mode, I/O6 stops toggling.
However, the system must also use I/O2 to determine which
sectors are erasing or erase-suspended. Alternatively, the

system can use I/O7 (see the subsection on " I/O7:
Polling").
Data
If a program address falls within a protected sector, I/O6
toggles for approximately 1µs after the program command
sequence is written, then returns to reading array data.
I/O6 also toggles during the erase-suspend-program mode,
and stops toggling once the Embedded Program algorithm is
complete.
Table 13 shows the outputs for Toggle Bit I on I/O6. Figure 6
shows the toggle bit algorithm. Figure 20 in the “AC
Characteristics” section shows the toggle bit timing diagrams.
Figure 23 shows the differences between I/O2 and I/O6 in
graphical form. See also the subsection on I/O2: Toggle Bit II.
Note:
The system should recheck the toggle bit even if I/O5=”1"
because the toggle bit may stop toggling as I/O5 changes to
“1”. See the subsections on I/O6 and I/O2 for more information.

I/O2: Toggle Bit II
I/O5: Exceeded Timing Limits
The "Toggle Bit II" on I/O2, when used with I/O6, indicates
whether a particular sector is actively erasing (that is, the
Embedded Erase algorithm is in progress), or whether that
sector is erase-suspended. Toggle Bit II is valid after the
I/O5 indicates whether the program or erase time has
exceeded a specified internal pulse count limit. Under these
conditions I/O5 produces a "1." This is a failure condition that
indicates the program or erase cycle was not successfully
completed.
The device may output a “1” on I/O5 if the system tries to
program a “1” to a location that was previously programmed
to “0.” Only an erase operation can change a “0” back to a
“1.” Under this condition, the device halts the operation, and
when the timing limit has been exceeded, I/O5 produces a
“1.” .

pulse in the command sequence.
WE
I/O2 toggles when the system reads at addresses within those
sectors that have been selected for erasure. (The system may
use either
or

CE_F
OE
cannot distinguish whether the sector is actively erasing or is
erase-suspended. I/O6, by comparison, indicates whether the
device is actively erasing, or is in Erase Suspend, but cannot
distinguish which sectors are selected for erasure. Thus, both
status bits are required for sector and mode information.
Refer to Table 8 to compare outputs for I/O2 and I/O6.
Under both these conditions, the system must write the reset
command to return to reading array data (or to the erase-
suspend-read mode if a bank was previously in the erase-
suspend-program mode).
Figure 6 shows the toggle bit algorithm in flowchart form, and
the section " I/O2: Toggle Bit II" explains the algorithm. See
also the " I/O6: Toggle Bit I" subsection. Figure 20 shows the
toggle bit timing diagram. Figure 21 shows the differences
between I/O2 and I/O6 in graphical form.
I/O3: Sector Erase Timer
After writing a sector erase command sequence, the system
may read I/O3 to determine whether or not an erase
operation has begun. (The sector erase timer does not apply
to the chip erase command.) If additional sectors are
selected for erasure, the entire time-out also applies after
each additional sector erase command. When the time-out is
complete, I/O3 switches from "0" to "1." The system may
ignore I/O3 if the system can guarantee that the time
between additional sector erase commands will always be
less than 50µs. See also the "Sector Erase Command
Sequence" section.
Reading Toggle Bits I/O6, I/O2
Refer to Figure 6 for the following discussion. Whenever the
system initially begins reading toggle bit status, it must read
I/O7-I/O0 at least twice in a row to determine whether a toggle
bit is toggling. Typically, a system would note and store the
value of the toggle bit after the first read. After the second
read, the system would compare the new value of the toggle
bit with the first. If the toggle bit is not toggling, the device has
completed the program or erase operation. The system can
read array data on I/O7-I/O0 on the following read cycle.
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the system also
should note whether the value of I/O5 is high (see the section
on I/O5). If it is, the system should then determine again
whether the toggle bit is toggling, since the toggle bit may
have stopped toggling just as I/O5 went high. If the toggle bit
is no longer toggling, the device has successfully completed
the program or erase operation. If it is still toggling, the device
did not complete the operation successfully, and the system
must write the reset command to return to reading array data.
The remaining scenario is that the system initially determines
that the toggle bit is toggling and I/O5 has not gone high. The
system may continue to monitor the toggle bit and I/O5
through successive read cycles, determining the status as
described in the previous paragraph. Alternatively, it may
choose to perform other system tasks. In this case, the
system must start at the beginning of the algorithm when it
returns to determine the status of the operation (top of Figure
6).
After the sector erase command sequence is written, the
system should read the status on I/O7 (
Polling) or I/O6
Data
(Toggle Bit 1) to ensure the device has accepted the
command sequence, and then read I/O3. If I/O3 is "1", the
internally controlled erase cycle has begun; all further
commands (Except Erase Suspend) are ignored until the
erase operation is complete. If I/O3 is "0", the device will
accept additional sector erase commands. To ensure the
command has been accepted, the system software should
check the status of I/O3 prior to and following each
subsequent sector erase command. If I/O3 is high on the
second status check, the last command might not have been
accepted.
Table 13 shows the status of I/O3 relative to the other status
bits.

2. I/O7 and I/O2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. When reading write operation status bits, the system must always provide the bank address where the Embedded Algorithm

Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0V VCC_F, 10,000 cycles. Additionally,
programming typically assumes checkerboard pattern.
2. Under worst case conditions of 90°C, VCC_F = 2.7V, 100,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
program faster than the maximum byte program time listed.
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 12
for further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 10,000 cycles.
