General Description
The A29L800A is an 8Mbit, 3.0 volt-only Flash memory
organized as 1,048,576 bytes of 8 bits or 524,288 words of 16
bits each. The 8 bits of data appear on I/O0 - I/O7; the 16 bits of
data appear on I/O0~I/O15. The A29L800A is offered in 48-ball
TFBGA, 44-pin SOP and 48-Pin TSOP packages. This device
is designed to be programmed in-system with the standard
system 3.0 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However, the
A29L800A can also be programmed in standard EPROM
programmers.
The A29L800A has the first toggle bit, I/O6, which indicates
whether an Embedded Program or Erase is in progress, or it is
in the Erase Suspend. Besides the I/O6 toggle bit, the
A29L800A has a second toggle bit, I/O2, to indicate whether
the addressed sector is being selected for erase. The
A29L800A also offers the ability to program in the Erase
Suspend mode. The standard A29L800A offers access times
of 70 and 90ns, allowing high-speed microprocessors to
operate without wait states. To eliminate bus contention the
The A29L800A is entirely software command set compatible
with the JEDEC single-power-supply Flash standard.
Commands are written to the command register using
standard microprocessor write timings. Register contents serve
as input to an internal state-machine that controls the erase
and programming circuitry. Write cycles also internally latch
addresses and data needed for the programming and erase
operations. Reading data out of the device is similar to reading
from other Flash or EPROM devices.
Device programming occurs by writing the proper program
command sequence. This initiates the Embedded Program
algorithm - an internal algorithm that automatically times the
program pulse widths and verifies proper program margin.
Device erasure occurs by executing the proper erase
command sequence. This initiates the Embedded Erase
algorithm
-
an internal algorithm that automatically
preprograms the array (if it is not already programmed) before
executing the erase operation. During erase, the device
automatically times the erase pulse widths and verifies proper
erase margin. The Unlock Bypass mode facilitates faster
programming times by requiring only two write cycles to
program data instead of four.
device has separate chip enable (

and output enable (

OE
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.
The host system can detect whether a program or erase
operation is complete by observing the RY /
pin, or by
BY
reading the I/O7 (
Polling) and I/O6 (toggle) status bits.

After a program or erase cycle has been completed, the device
is ready to read array data or accept another command.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data contents
of other sectors. The A29L800A is fully erased when shipped
from the factory.
The Erase Suspend/Erase Resume feature enables the user
to put erase on hold for any period of time to read data from,
or program data to, any other sector that is not selected for
erasure. True background erase can thus be achieved.
The hardware
pin terminates any operation in
RESET
progress and resets the internal state machine to reading
array data. The pin may be tied to the system reset
circuitry. A system reset would thus also reset the device,
enabling the system microprocessor to read the boot-up
firmware from the Flash memory.
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 these modes.

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 Mode
The autoselect mode provides manufacturer and device
identification, through identifier codes output on I/O7 - I/O0.
This mode is primarily intended for programming equipment to
automatically match a device to be programmed with its
corresponding programming algorithm. However, the
autoselect codes can also be accessed in-system through the
command register.
When using programming equipment, the autoselect mode
requires VID (11.5V to 12.5 V) on address pin A9. Address pins
A6, A1, and A0 must be as shown in Autoselect Codes (High
Voltage Method) table. In addition, when verifying sector
protection, the sector address must appear on the appropriate
highest order address bits. Refer to the corresponding Sector
Address Tables. The Command Definitions table shows the
remaining address bits that are don't care. When all necessary
bits have been set as required, the programming equipment
may then read the corresponding identifier code on I/O7 -
I/O0.To access the autoselect codes in-system, the host
system can issue the autoselect command via the command
register, as shown in the Command Definitions table. This
method does not require VID. See "Command Definitions" for
details on using the autoselect mode.

Command Definitions
Autoselect Command Sequence
Writing specific address and data commands or sequences into
the command register initiates device operations. The
Command Definitions table defines the valid register command
sequences. Writing incorrect address and data values or writing
them in the improper sequence resets the device to reading
array data.
The autoselect command sequence allows the host system to
access the manufacturer and devices codes, and determine
whether or not a sector is protected. The Command Definitions
table shows the address and data requirements. This method is
an alternative to that shown in the Autoselect Codes (High
Voltage Method) table, which is intended for PROM
programmers and requires VID on address bit A9.
The autoselect command sequence is initiated by writing two
unlock cycles, followed by the autoselect command. The device
then enters the autoselect mode, and the system may read at
any address any number of times, without initiating another
command sequence.
A read cycle at address XX00h retrieves the manufacturer code
and another read cycle at XX03h retrieves the continuation
code. A read cycle at address XX01h returns the device code. A
read cycle containing a sector address (SA) and the address
02h in returns 01h if that sector is protected, or 00h if it is
unprotected. Refer to the Sector Address tables for valid sector
addresses.
All addresses are latched on the falling edge of
or

WE
whichever happens later. All data is latched on the rising edge

WE
CE
appropriate timing diagrams in the "AC Characteristics" section.
Reading Array Data
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 device enters
the Erase Suspend mode. The system can read array data
using the standard read timings, except that if it reads at an
address within erase-suspended sectors, the device outputs
status data. After completing a programming operation in the
Erase Suspend mode, the system may once again read array
data with the same exception. See "Erase Suspend/Erase
Resume Commands" for more information on this mode.
The system must issue the reset command to re-enable the
device for reading array data if I/O5 goes high, or while in the
autoselect mode. See the "Reset Command" section, next.
See also "Requirements for Reading Array Data" in the "Device
Bus Operations" section for more information. The Read
Operations table provides the read parameters, and Read
Operation Timings diagram shows the timing diagram.
The system must write the reset command to exit the autoselect
mode and return to reading array data.
Word/Byte Program Command Sequence
The system may program the device by word or byte,
depending on the state of the
pin. Programming is a four-
BYTE
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 verify the programmed cell
margin. Table 5 shows the address and data requirements for
the byte program command sequence.
Reset Command
Writing the reset command to the device resets the device to
reading array data. Address bits are don't care for this
command. The reset command may be written between the
sequence cycles in an erase command sequence before
erasing begins. This resets the device to reading array data.
Once erasure begins, however, the device ignores reset
commands until the operation is complete.
The reset command may be written between the sequence
cycles in a program command sequence before programming
begins. This resets the device to reading array data (also
applies to programming in Erase Suspend mode). Once
programming begins, however, the device ignores reset
commands until the operation is complete.
When the Embedded Program algorithm is complete, the device
then returns to reading array data and addresses are longer
latched. The system can determine the status of the program
operation by using I/O7, I/O6, or RY/
. See “White Operation
BY
Status” for information on these status bits.
Any commands written to the device during the Embedded
Program Algorithm are ignored. Note that a hardware reset
immediately terminates the programming operation. The Byte
Program command sequence should be reinitiated once the
device has reset to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across sector
boundaries. A bit cannot be programmed from a “0” back to a
“1”. Attempting to do so may halt the operation and set I/O5 to
The reset command may be written between the sequence
cycles in an autoselect command sequence. Once in the

Suspend).

Polling algorithm to indicate the
Data
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”.
If I/O5 goes high during a program or erase operation, writing
the reset command returns the device to reading array data
(also applies during Erase Suspend).

Chip Erase Command Sequence
Chip erase is a six-bus-cycle operation. The chip erase
command sequence is initiated by writing two unlock cycles,
followed by a set-up command. Two additional unlock write
cycles are then followed by the chip erase command, which in
turn invokes the Embedded Erase algorithm. The device does
not require the system to preprogram prior to erase. The
Embedded Erase algorithm automatically preprograms 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. The Command
Definitions table shows the address and data requirements for
the chip erase command sequence.
Any commands written to the chip during the Embedded Erase
algorithm are ignored. The system can determine the status of
the erase operation by using I/O7, I/O6, or I/O2. See "Write

Embedded Erase algorithm is complete, the device returns to
reading array data and addresses are no longer latched.

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 write
cycles are then followed by the address of the sector to be
erased, and the sector erase command. The Command
Definitions table shows the address and data requirements for
the sector erase command sequence.
Note : See the appropriate Command Definitions table for
program command sequence.
The device does not require the system to preprogram the
memory prior to erase. The Embedded Erase algorithm
automatically programs and verifies the sector 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 50µs begins. During the time-out period, additional sector
addresses and sector erase commands 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 the last address and command might not
be accepted, and erasure may begin. 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. If the time between
additional sector erase commands can be assumed to be less
than 50µs, the system need not monitor I/O3. Any command
other than Sector Erase or Erase Suspend during the time-out
period resets the device to reading array data. The system must
rewrite the command sequence and any additional sector
addresses and commands.
Figure 1. Program Operation
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to program bytes
or words to the device 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 mode. 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 program 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 5 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 first cycle
must contain the data 90h; the second cycle the data 00h.
The system can monitor I/O3 to determine if the sector erase
timer has timed out. (See the " I/O3: Sector Erase Timer"
(June, 2005, Version 1.1)
11
AMIC Technology, Corp.
A29L800A Series
section.) The time-out begins from the rising edge of the final
pulse in the command sequence.
The system may also write the autoselect command sequence
when the device is in the Erase Suspend mode. The device
allows reading autoselect codes even at addresses within
erasing sectors, since the codes are not stored in the memory
array. When the device exits the autoselect mode, the device
reverts to the Erase Suspend mode, and is ready for another
valid operation. See "Autoselect Command Sequence" for
more information.
The system must write the Erase Resume command (address
bits are "don't care") to exit the erase suspend mode and
continue the sector erase operation. Further writes of the
Resume command are ignored. Another Erase Suspend
command can be written after the device has resumed erasing.
WE
Once the sector erase operation has begun, only the Erase
Suspend command is valid. All other commands are ignored.
When the Embedded Erase algorithm is complete, the device
returns to reading array data and addresses are no longer
latched. The system can determine the status of the erase
operation by using I/O7, I/O6, or I/O2. Refer to "Write Operation
Status" for information on these status bits.
Figure 2 illustrates the algorithm for the erase operation. Refer
to the Erase/Program Operations tables in the "AC
Characteristics" section for parameters, and to the Sector
Erase Operations Timing diagram for timing waveforms.
Erase Suspend/Erase Resume Commands
The Erase Suspend command 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 50µs
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. Writing
the Erase Suspend command during the Sector Erase time-out
immediately terminates the time-out period and suspends the
erase operation. Addresses are "don't cares" when writing the
Erase Suspend command.
When the Erase Suspend command is written during a sector
erase operation, the device requires a maximum of 20µs 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 system can

selected for erasure.) Normal read and write timings and
command definitions apply. Reading at any address within
erase-suspended sectors produces status data on I/O7 - I/O0.

Write Operation Status
Several bits, I/O2, I/O3, I/O5, I/O6, I/O7, RY/
are provided in
BY
the A29L800A to determine the status of a write operation.
Table 6 and the following subsections describe the functions of
START
these status bits. I/O7, I/O6 and RY/
each offer a method for
BY
determining whether a program or erase operation is complete
or in progress. These three bits are discussed first.

During the Embedded Program algorithm, the device outputs

I/O7 status also applies to programming during Erase
Suspend. When the Embedded Program algorithm is
complete, the device outputs the datum programmed to I/O7.
The system must provide the program address to read valid

Polling produces a "1" on I/O7.This is analogous to the
Data
complement/true datum output described for the Embedded
Program algorithm: the erase function changes all the bits in a
sector to "1"; prior to this, the device outputs the "complement,"
or "0." The system must provide an address within any of the
sectors selected for erasure to read valid status information on
I/O7.
Yes
I/O7 = Data ?
When the system detects I/O7 has changed from the
complement to true data, it can read valid data at I/O7 - I/O0 on
the following read cycles. This is because I/O7 may change

Note :
1. VA = Valid address for programming. During a sector
erase operation, a valid address is an address within any
sector selected for erasure. During chip erase, a valid
address is any non-protected sector address.
2. I/O7 should be rechecked even if I/O5 = "1" because
I/O7 may change simultaneously with I/O5.

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 6 to compare outputs for I/O2 and I/O6.
Figure 4 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. Refer to the Toggle
Bit Timings figure for the toggle bit timing diagram. The I/O2
vs. I/O6 figure shows the differences between I/O2 and I/O6 in
graphical form.
The RY/
is a dedicated, open-drain output pin that indicates
BY
whether an Embedded algorithm is in progress or complete.
The RY/

If the output is low (Busy), the device is actively erasing or
programming. (This includes programming in the Erase
Suspend mode.) If the output is high (Ready), the device is
ready to read array data (including during the Erase Suspend
mode), or is in the standby mode.
Reading Toggle Bits I/O6, I/O2
Table 6 shows the outputs for RY/
. Refer to “
RESET
BY
Refer to Figure 4 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
4).
Timings”, “Timing Waveforms for Program Operation” and
“Timing Waveforms for Chip/Sector Erase Operation” for more
information.
I/O6: Toggle Bit I
Toggle Bit I on I/O6 indicates whether an Embedded Program
or Erase algorithm is in progress or complete, or whether the
device has entered the Erase Suspend mode. Toggle Bit I may
be read at any address, and is valid after the rising edge of the
final
pulse in the command sequence (prior to the
WE
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.
(The system may use either
or
to control the read
CE
OE
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/O5: Exceeded Timing Limits
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 I/O5 failure condition may appear if the system tries to
program a "1 "to a location that is 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 operation has exceeded the timing limits, I/O5 produces a
"1."
I/O7 (see the subsection on " I/O7 :
Polling").
Data
I/O6 also toggles during the erase-suspend-program mode, and
stops toggling once the Embedded Program algorithm is
complete.
The Write Operation Status table shows the outputs for Toggle
Bit I on I/O6. Refer to Figure 4 for the toggle bit algorithm, and
to the Toggle Bit Timings figure in the "AC Characteristics"
section for the timing diagram. The I/O2 vs. I/O6 figure shows
the differences between I/O2 and I/O6 in graphical form. See
also the subsection on " I/O2: Toggle Bit II".
Under both these conditions, the system must issue the reset
command to return the device to reading array data.
I/O2: Toggle Bit II
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 rising
edge of the final
I/O2 toggles when the system reads at addresses within those
pulse in the command sequence.

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.

sequence, and then read I/O3. If I/O3 is "1", the internally
controlled erase cycle has begun; all further commands (other
than 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 6 shows the
outputs for I/O3.

Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0V VCC, 10,000 cycles. Additionally, programming
typically assumes checkerboard pattern.
2. Under worst case conditions of 90°C, VCC = 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. If the maximum byte program time given is exceeded, only then does
the device set I/O5 = 1. See the section on I/O5 for further information.
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 5 for
further information on command definitions.
6. The device has a guaranteed minimum erase and program cycle endurance of 10,000 cycles.
