GENERAL DESCRIPTION
A29DL16x Features
The A29DL16x family consists of 16 megabit, 3.0 volt-only
flash memory devices, organized as 1,048,576 words of 16
bits each or 2,097,152 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 is available with an access time of 70, 90, or 120
ns. The devices are offered in 48-pin TSOP and 48-ball Finepitch BGA. Standard control pins—chip enable ( CE ), write
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 host system can detect whether a program or erase
operation is complete by using the device status bits:
RY/ BY pin, I/O7 ( Data Polling) and I/O6/I/O2 (toggle 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.
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
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.
enable ( WE ), and output enable ( OE )—control normal read
and write 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.
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
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 A29DL16x devices uses multiple bank architectures 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.

2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the
“Sector/Sector Block Protection and Unprotection” section.
3. If WP /ACC = VIL, the two outermost boot sectors remain protected. If WP /ACC = VIH, the two outermost boot sector
protection depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block
Protection and Unprotection”. If WP /ACC = VHH all sectors will be unprotected.

Accelerated Program Operation
Word/Byte Configuration
The device offers accelerated program operations through
the ACC function. This is one of two functions provided by
the WP /ACC pin. This function is primarily intended to allow
faster manufacturing throughput at the factory.
If the system asserts VHH on this pin, the device automatically
enters the aforementioned Unlock Bypass mode, temporarily
unprotects any protected sectors, and uses the higher
voltage on the pin to reduce the time required for program
operations. The system would use a two-cycle program
command sequence as required by the Unlock Bypass
mode. Removing VHH from the WP /ACC pin returns the
device to normal operation. Note that the WP /ACC pin must
not be at VHH for operations other than accelerated programming, or device damage may result. In addition, the
WP /ACC pin must not be left floating or unconnected;
inconsistent behavior of the device may result.
The BYTE pin determines whether the I/O pins I/O15-I/O0
operate in the byte or word configuration. If the BYTE pin is
set at logic ”1”, the device is in word configuration, I/O15-I/O0
are active and controlled by CE and OE .
If the BYTE pin is set at logic “0”, the device is in byte
configuration, and only I/O0-I/O7 are active and controlled by
CE and OE . I/O8-I/O14 are tri-stated, and I/O15 pin is used
as an input for the LSB(A-1) address function.
Requirements for Reading Array Data
To read array data from the outputs, the system must drive
the CE and OE pins to VIL. CE is the power control and
selects the device. OE is the output control and gates array
data to the output pins. WE should remain at VIH. The
BYTE pin determines whether the device outputs array data
in words or bytes.
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 in the DC Characteristics table represents the
active current specification for reading array data.
Autoselect Functions
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 and ICC7 in the DC Characteristics
table represent the current specifications for read-while-program 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 WE and CE to VIL, and
Standby Mode
OE to VIH.
When the system is not reading or writing to the device, it
can place the device in the standby mode. In this mode,
current consumption is greatly reduced, and the outputs are
placed in the high impedance state, independent of the OE
input.
For program operations, the BYTE pin determines whether
the device accepts program data in bytes or words, Refer to
“Word/Byte Configuration” for more information.
The device features an Unlock Bypass mode to facilitate
faster programming. Once a bank enters the Unlock Bypass
mode, only two write cycles are required to program a word
or byte, instead of four. The “Word / Byte Program Command
Sequence” section has details on programming data to the
device using both standard and Unlock Bypass command
sequence.
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
sector.
ICC2 in the DC Characteristics table represents the active
current specification for the write mode. The "AC
Characteristics" section contains timing specification tables
and timing diagrams for write operations.
PRELIMINARY
(September, 2004, Version 0.0)
The device enters the CMOS standby mode when the CE &
RESET pins are both held at VCC ± 0.3V. (Note that this is a
more restricted voltage range than VIH.) If CE and RESET
are held at VIH, but not within VCC ± 0.3V, the device will be
in the standby mode, but the standby current will be greater.
The device requires the standard access time (tCE) for read
access when the device is in either of these standby modes,
before it is ready to read data.
If the device is deselected during erasure or programming,
the device draws active current until the operation is
completed.
ICC3 in the DC Characteristics tables represent the standby
current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy
consumption. The device automatically enables this mode
when addresses remain stable for tACC +30ns. The automatic

The RESET pin may be tied to the system reset circuitry. A
system reset would thus also reset the Flash memory,
enabling the system to read the boot-up firmware from the
Flash memory.
If RESET is asserted during a program or erase operation,
sleep mode is independent of the CE , WE and OE control
signals. Standard address access timings provide new data
when addresses are changed. While in sleep mode, output
data is latched and always available to the system. ICC4 in the
DC Characteristics table represents the automatic sleep
mode current specification.
the RY/ BY pin remains a “0” (busy) until the internal reset
operation is complete, which requires a time tREADY (during
Embedded Algorithms). The system can thus monitor
RY/ BY to determine whether the reset operation is
complete. If RESET is asserted when a program or erase
RESET : Hardware Reset Pin
The RESET pin provides a hardware method of resetting
the device to reading array data. When the system drives the
RESET pin low for at least a period of tRP, the device
immediately terminates any operation in progress, tristates
all data output pins, and ignores all read/write attempts for
the duration of the RESET pulse. The device also resets the
internal state machine to reading array data. The operation
that was interrupted should be reinitiated once the device is
ready to accept another command sequence, to ensure data
integrity.
Current is reduced for the duration of the RESET pulse.
When RESET is held at VSS ± 0.3V, the device draws
CMOS standby current (ICC4 ). If RESET is held at VIL but not
within VSS ± 0.3V, the standby current will be greater.
operation is not executing (RY/ BY pin is “1”), the reset
operation is completed within a time of tREADY (not during
Embedded Algorithms). The system can read data tRH after
the RESET pin return to VIH.
Refer to the AC Characteristics tables for RESET
parameters and diagram.
Output Disable Mode
When the OE input is at VIH, output from the device is
disabled. The output pins are placed in the high impedance
state.

Autoselect Mode
The autoselect mode provides manufacturer and device
identification, and sector protection verification, 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 (8.5V to 12.5 V) on address pin A9. Address
pins A6, A1, and A0 must be as shown in Table 5. In
addition, when verifying sector protection, the sector address
must appear on the appropriate highest order address bits.
(see Table 3-4). Table 5 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 Table 12. This method does not require
VID. Refer to the Autoselect Command Sequence section for
more information.

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.
The primary method requires VID on the RESET pin only,
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”.
The alternate method for protection and unprotection is by
software sector /sector block protect 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.
Sector/Sector Block Protection and Unprotection
(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).

Write Protect ( WP )
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 WP /ACC pin.
If the system asserts VIL on the WP /ACC pin, the device
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 WP /ACC pin, the device
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 WP /ACC pin must not be left floating or
unconnected; inconsistent behavior of the device may result.

two or more adjacent sectors that are protected or

This feature allows temporary unprotection of previously
protected sectors to change data in-system. The Sector
Unprotect mode is activated by setting the RESET pin to VID
(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 RESET pin, all the
previously protected sectors are protected again. Figure 1
shows the algorithm, and Figure 22 shows the timing

Hardware Data Protection
Power-Up Write Inhibit
The command sequence requirement of unlock cycles for
programming or erasing provides data protection against
inadvertent writes (refer to Table 12 for command definitions).
In addition, the following hardware data protection measures
prevent accidental erasure or programming, which might
otherwise be caused by spurious system level signals during
VCC power-up and power-down transitions, or from system
noise.
If WE = CE = VIL and OE = VIH during power up, the
device does not accept commands on the rising edge of WE .
The internal state machine is automatically reset to reading
array data on power-up.
Low VCC Write Inhibit
When VCC is less than VLKO, the device does not accept any
write cycles. This protects data during VCC power-up and
power-down. The command register and all internal
program/erase circuits are disabled, and the device resets to
reading array data. Subsequent writes are ignored until VCC
is greater than VLKO. The system must provide the proper
signals to the control pins to prevent unintentional writes
when VCC is greater than VLKO.
Write Pulse “Glitch” Protection
Noise pulses of less than 5ns (typical) on OE , CE or WE
do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by holding any one of OE = VIL,
CE = VIH or WE = VIH. To initiate a write cycle, CE and
COMMON FLASH MEMORY INTERFACE (CFI)
The Common Flash Interface (CFI) specification outlines
device and host system software interrogation handshake,
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
mode (or address AAh in byte mode), any time the device is
ready to read array data. The system can read CFI
information at the addresses given in Tables 8-11. To
terminate reading CFI data, the system must write the reset
command.
The system can also write the CFI query command when the
device is in the autoselect mode. The device enters the CFI
query mode, and the system can read CFI data at the
addresses given in Tables 8-11. The system must write the
reset command to return the device to the autoselect mode.
WE must be a logical zero while OE is a logical one.

Suspend).
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.
All addresses are latched on the falling edge of WE or CE ,
whichever happens later. All data is latched on the rising
edge of WE or CE , whichever happens first. Refer to the
AC Characteristics section for timing diagrams.
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 erasesuspend-read mode. The autoselect command may not be
written while the device is actively programming or erasing in
the other bank.
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.
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).
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
corresponding bank enters the erase-suspend-read mode,
after which the system can read data from any non-erasesuspended 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.
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 BYTE 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
the program operation by using I/O7, I/O6, or RY/ BY . Refer
to the Write Operation Status section 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 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.”
Reset Command
Writing the reset command resets the banks to the read or
erase-suspend-read mode. Address bits are don’t cares for
this command.
The reset command may be written between the sequence
cycles in an erase command sequence before erasing
begins. This resets the bank to which the system was writing
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 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

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
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
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 twocycle unlock bypass reset command sequence. The device
then returns to reading array data.
The device offers accelerated program operations through
the WP /ACC pin. When the system asserts VHH on the
WP /ACC pin, the device automatically enters the Unlock
Bypass mode. The system may then write the two-cycle
Unlock Bypass program command sequence. The device
uses the higher voltage on the WP /ACC pin to accelerate
the operation. Note that the WP /ACC pin must not be at VHH
any operation other than accelerated programming, or device
damage may result. In addition, the WP /ACC pin must not
be left floating or unconnected; inconsistent behavior of the
device may result.
Figure 3 illustrates the algorithm for the program operation.

When the Embedded Erase algorithm is complete, the bank
returns to reading array data and addresses are no longer
latched. Note that while the Embedded Erase operation is in
progress, the system can read data from the non-erasing
bank. The system can determine the status of the erase
operation by reading I/O7, I/O6, I/O2, or RY/ BY in the erasing
bank.
Refer to the Write Operation Status section for information on
these status bits.
Once the sector erase operation has begun, only the Erase
Suspend command is valid. All other commands are ignored.
However, note that a hardware reset immediately terminates
the erase operation. If that occurs, the sector erase
command sequence should be reinitiated once that bank has
returned to reading array data, to ensure data integrity.
Figure 4 illustrates the algorithm for the erase operation.
Refer to the Erase and Program Operations tables in the AC
Characteristics section for parameters, and Figure 17 section
for timing diagrams
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. Table 12
shows the address and data requirements for the chip erase
command sequence.
When the Embedded Erase algorithm is complete, that bank
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, I/O2, or RY/ BY . Refer to the
Write Operation Status section for information on these
status bits.
Any commands written during the chip erase operation are
ignored. However, note that a hardware reset immediately
terminates the erase operation. If that occurs, the chip erase
command sequence should be reinitiated once that bank has
returned to reading array data, to ensure data integrity.
Figure 4 illustrates the algorithm for the erase operation.
Refer to the Erase and Program Operations tables in the AC
Characteristics section for parameters, and Figure 17 section
for timing diagrams.
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.
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 timeout, 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.
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
Erase Suspend command can be written after the chip has
resumed erasing.
Sector Erase Command Sequence
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 timeout 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
WE pulse in the command sequence.

WRITE OPERATION STATUS
The device provides several bits to determine the status of a
program or erase operation: I/O2, I/O3, I/O5, I/O6, and I/O7.
Table 13 and the following subsections describe the function
of these bits. I/O7 and I/O6 each offer a method for
determining whether a program or erase operation is
complete or in progress. The device also provides a
hardware-based output signal, RY/ BY , to determine whether
an Embedded Program or Erase operation is in progress or
has been completed.
START
Read I/O7-I/O0
Address = VA
I/O7: Data Polling
Yes
The Data Polling bit, I/O7, indicates to the host system
whether an Embedded Algorithm is in progress or completed,
or whether the device is in Erase Suspend. Data Polling is
I/O7 = Data ?
valid after the rising edge of the final WE pulse in the
program or erase command sequence.
During the Embedded Program algorithm, the device outputs
on I/O7 the complement of the datum programmed to I/O7.
This 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
status information on I/O7. If a program address falls within a
protected sector, Data Polling on I/O7 is active for
approximately 1µs, then the device returns to reading array
data.
During the Embedded Erase algorithm, Data Polling
produces a "0" on I/O7. When the Embedded Erase algorithm
is complete, or if the device enters the Erase Suspend mode,
Data Polling produces a "1" on I/O7. The system must
provide an address within any of the sectors selected for
erasure to read valid status information on I/O7.
After an erase command sequence is written, if all sectors
selected for erasing are protected, Data Polling on I/O7 is
active for approximately 100µs, then the bank 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.
However, if the system reads I/O7 at an address within a
protected sector, the status may not be valid.
Just prior to the completion of an Embedded Program or
Erase operation, I/O7 may change asynchronously with I/O0–
I/O6 while Output Enable ( OE ) is asserted low. That is, the
device may change from providing status information to valid
data on I/O7. Depending on when the system samples the
I/O7 output, it may read the status or valid data. Even if the
device has completed the program or erase operation and
I/O7 has valid data, the data outputs on I/O0-I/O6 may be still
invalid. Valid data on I/O0-I/O7 will appear on successive read
cycles.

Note :
1. VA = Valid address for programming. During a sector

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.

RY/ BY : Read/ Busy
The RY/ BY is a dedicated, open-drain output pin that
indicates whether an Embedded algorithm is in progress or
complete. The RY/ BY status is valid after the rising edge of
the final WE pulse in the command sequence. Since RY/ BY
is an open-drain output, several RY/ BY pins can be tied
together in parallel with a pull-up resistor to VCC.
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.
Table 13 shows the outputs for RY/ BY .

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 WE pulse in the command sequence (prior to the
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 OE or CE to control the read
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 : Data
Polling").
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.

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 WE pulse in the command sequence.
I/O2 toggles when the system reads at addresses within those
sectors that have been selected for erasure. (The system may
use either OE or CE to control the read cycles.) But I/O2
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.
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.
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
PRELIMINARY
(September, 2004, Version 0.0)
25
returns to determine the status of the operation (top of Figure
6).
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 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.” .
Under both these conditions, the system must write the reset
command to return to reading array data (or to the erasesuspend-read mode if a bank was previously in the erasesuspend-program mode).
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.
After the sector erase command sequence is written, the
system should read the status on I/O7 ( Data Polling) or I/O6
(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.

Notes:

Refer to the section on I/O5 for more information.
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
is in progress. The device outputs array data if the system addresses a non-busy bank.

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.
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.
