General Description
The A29010B is a 5.0 volt-only Flash memory organized as
131,072 bytes of 8 bits each. The 128 Kbytes of data are
further divided into four sectors for flexible sector erase
capability. The 8 bits of data appear on I/O0 - I/O7 while the
addresses are input on A0 to A16. The A29010B is offered in
32-pin PLCC, TSOP, and PDIP packages. This device is
designed to be programmed in-system with the standard
system 5.0 volt VCC supply. Additional 12.0 volt VPP is not
required for in-system write or erase operations. However, the
A29010B can also be programmed in standard EPROM
programmers.
The A29010B 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 A29010B
has a second toggle bit, I/O2, to indicate whether the addressed
sector is being selected for erase. The A29010B also offers the
ability to program in the Erase Suspend mode. The standard
A29010B offers access times of 55ns allowing high-speed
microprocessors to operate without wait states. To eliminate
bus contention the device has separate chip enable ( CE ),
write enable ( WE ) and output enable ( OE ) controls.
The device requires only a single 5.0 volt power supply for both
read and write functions. Internally generated and regulated
voltages are provided for the program and erase operations.
The A29010B 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 host system can detect whether a program or erase
operation is complete by reading the I/O7 ( Data 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 A29010B is fully erased when shipped
from the factory.
The hardware sector protection feature disables operations for
both program and erase in any combination of the sectors
of memory. This can be achieved via programming equipment.
The Erase Suspend 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.
Power consumption is greatly reduced when the device is
placed in the standby mode.

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.

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 all the time during read
operation. 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. The device
remains enabled for read access until the command register
contents are altered.
See "Reading Array Data" for more information. Refer to the AC
Read Operations table for timing specifications and to the Read
Operations Timings diagram for the timing waveforms, lCC1 in
the DC Characteristics table represents the active current
specification for reading array data.
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 OE
to VIH. An erase operation can erase one sector, multiple
sectors, or the entire device. The Sector Address Tables
indicate the address range that each sector occupies. A "sector
address" consists of the address inputs required to uniquely
select a sector. See the "Command Definitions" section for
details on erasing a sector or the entire chip, or
suspending/resuming the erase operation.
After 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.
ICC2 in the 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.
Program and Erase Operation Status
During an erase or program operation, the system may check
the status of the operation by reading the status bits on I/O7 I/O0. Standard read cycle timings and ICC read specifications
apply. Refer to "Write Operation Status" for more information,
and to each AC Characteristics section for timing diagrams.
Standby Mode
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.
The device enters the CMOS standby mode when the CE is
held at VCC ± 0.5V. (Note that this is a more restricted voltage
range than VIH.) The device enters the TTL standby mode when
CE is held at VIH. The device requires the standard access
time (tCE) 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 represents the standby
current specification.
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 (9.5V to 11.5 V) on address pinA9. 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.

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.
Sector Protection/Unprotection
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/unprotection must be implemented using
programming equipment. The procedure requires a high
voltage (VID) on address pin A9 and the control pins.
The device is shipped with all sectors unprotected.
It is possible to determine whether a sector is protected or
unprotected. See "Autoselect Mode" for details.
Hardware Data Protection
Reset Command
The requirement of command unlocking sequence for
programming or erasing provides data protection against
inadvertent writes (refer to the Command Definitions table). 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 transitions, or from system noise. The device is
powered up to read array data to avoid accidentally writing
data to the array.
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.
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 (also applies to autoselect during Erase
Suspend).
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).
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 WE
must be a logical zero while OE is a logical one.
Power-Up Write Inhibit
If WE = CE = VIL and OE = VIH during power up, the device
Autoselect Command Sequence
does not accept commands on the rising edge of WE . The
internal state machine is automatically reset to reading array
data on the initial power-up.
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.
Command Definitions
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.
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
appropriate timing diagrams in the "AC Characteristics"
section.
Byte Program Command Sequence
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 verify the programmed cell margin. The Command
Definitions table shows the address and data requirements for
the byte program command sequence.
When the Embedded Program algorithm is complete, the
device then returns to reading array data and addresses are
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

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 Operation Status" for information on these status bits.
When the Embedded Erase algorithm is complete, the device
returns to reading array data and addresses are no longer
latched.
Figure 2 illustrates the algorithm for the erase operation. See
the Erase/Program Operations tables in "AC Characteristics"
for parameters, and to the Chip/Sector Erase Operation
Timings for timing waveforms.
no longer latched. The system can determine the status of the
program operation by using I/O7 or I/O6. See "Write Operation
Status" for information on these status bits.
Any commands written to the device during the Embedded
Program Algorithm are ignored. 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 "1", or cause the Data
Polling algorithm 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".
START
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 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.
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 timeout 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.
The system can monitor I/O3 to determine if the sector erase
timer has timed out. (See the " I/O3: Sector Erase Timer"
section.) The time-out begins from the rising edge of the final
WE pulse in the command sequence.
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.

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

followed by a set-up command. Two additional unlock write
cycles are then followed by the chip erase command, which in

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.
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 read array data from or program data to any sector not
selected for erasure. (The device "erase suspends" all sectors
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.
The system can use I/O7, or I/O6 and I/O2 together, to
determine if a sector is actively erasing or is erasesuspended. See "Write Operation Status" for information on
these status bits.
After an erase-suspended program operation is complete, the
system can once again read array data within non-suspended
sectors. The system can determine the status of the program
operation using the I/O7 or I/O6 status bits, just as in the
standard program operation. See "Write Operation Status" for
more information.
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.

Write Operation Status
Several bits, I/O2, I/O3, I/O5, I/O6, and I/O7, are provided in the
A29010B to determine the status of a write operation. Table 5
and the following subsections describe the functions of these
status bits. I/O7, I/O6 and I/O2 each offer a method for
determining whether a program or erase operation is complete
or in progress. These three bits are discussed first.
START
Read I/O7-I/O0
Address = VA
I/O7: Data Polling
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
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 2μs, 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.This is analogous to the
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.
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 device 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.
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
asynchronously with I/O0 - I/O6 while Output Enable ( OE ) is
asserted low. The Data Polling Timings (During Embedded
Algorithms) figure in the "AC Characteristics" section
illustrates this. Table 5 shows the outputs for Data Polling on
I/O7. Figure 3 shows the Data Polling algorithm.

I/O7 = Data ?
No
No
I/O5 = 1?

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.

I/O6: Toggle Bit I
Reading Toggle Bits I/O6, I/O2
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 timeout.
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 2μs 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.
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".
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).
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 5 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.

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."
Under both these conditions, the system must issue the reset
command to return the device to reading array data.
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 (other than Erase Suspend) are ignored until the
erase operation is complete. If I/O3 is "0", the device will
AMIC Technology, Corp.
A29010B Series
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 5 shows the outputs for I/O3.

Comments
Excludes 00h programming prior to
erasure (Note 4)
Excludes system-level overhead (Note 5)
Notes:
1. Typical program and erase times assume the following conditions: 25°C, 5.0V VCC, 10,000 cycles. Additionally, programming
typically assumes checkerboard pattern.
2. Under worst case conditions of 90°C, VCC = 4.5V (4.75V for -55), 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 4 for
further information on command definitions.
6. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles.
