Am29F010
GENERAL DESCRIPTION
The Am29F010 is a 1 Mbit, 5.0 Volt-only Flash memory
organized as 131,072 bytes. The Am29F010 is offered
in 32-pin PLCC, TSOP, and PDIP packages. The byte-
wide data appears on DQ0-DQ7. The device is de-
signed to be programmed in-system with the standard
system 5.0 Volt V
CC
supply. A 12.0 volt V
PP
is not re-
quired for program or erase operations. The device can
also be programmed or erased in standard EPROM
programmers.
The standard device offers access times of 45, 55, 70,
90, and 120 ns, allowing high-speed microprocessors
to operate without wait states. To eliminate bus con-
tention 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 sup-
ply
for both read and write functions. Internally gener-
ated and regulated voltages are provided for the
program and erase operations.
The device is entirely command set compatible with the
JEDEC single-power-supply Flash standard. Com-
mands are written to the command register using stan-
dard 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 pro-
gramming and erase operations. Reading data out of
the device is similar to reading from other Flash or
EPROM devices.
Device programming occurs by executing the program
command sequence. This invokes the Embedded
Program
algorithm--an internal algorithm that auto-
matically times the program pulse widths and verifies
proper cell margin.
Device erasure occurs by executing the erase com-
mand sequence. This invokes the Embedded Erase
algorithm--an internal algorithm that automatically pre-
programs the array (if it is not already programmed) be-
fore executing the erase operation. During erase, the
device automatically times the erase pulse widths and
verifies proper cell margin.
The host system can detect whether a program or
erase operation is complete by reading the DQ7 (Data#
Polling) and DQ6 (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 device is erased
when shipped from the factory.
The hardware data protection measures include a
low V
CC
detector automatically inhibits write operations
during power transitions. The hardware sector pro-
tection
feature disables both program and erase oper-
ations in any combination of the sectors of memory,
and is implemented using standard EPROM program-
mers.
The system can place the device into the standby mode.
Power consumption is greatly reduced in this mode.
AMD's Flash technology combines years of Flash
memory manufacturing experience to produce the
h i g h e s t l e v e l s o f q u a l i t y, re l i a b il i t y, a n d c o s t
effectiveness. The device electrically erases all bits
within a sector simultaneously via Fowler-Nordheim
tunneling. The bytes are programmed one byte at a
time using the EPROM programming mechanism of
hot electron injection.

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 com-
mands, 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 re-
sulting output. The following subsections describe
each of these operations in further detail.

Notes:
1. Addresses are A16:A0.
2. The sector protect and sector unprotect functions must be implemented via programming equipment. See the "Sector Pro-
tection/Unprotection" section.
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE# and OE# pins to V
IL
. CE# is the power
control and selects the device. OE# is the output control
and gates array data to the output pins. WE# should re-
main at V
IH
.
The internal state machine is set for reading array
data upon device power-up, or after a hardware re-
set. 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 specifica-
tions and to the Read Operations Timings diagram for
the timing waveforms. I
CC1
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 in-
cludes programming data to the device and erasing
sectors of memory), the system must drive WE# and
CE# to V
IL
, and OE# to V
IH
.
An erase operation can erase one sector, multiple sec-
tors, or the entire device. The Sector Address Tables
indicate the address space that each sector occupies.
A "sector address" consists of the address bits required
to uniquely select a sector. See the "Command Defini-
tions" section for details on erasing a sector or the en-
tire chip.
After the system writes the autoselect command se-
quence, the device enters the autoselect mode. The
system can then read autoselect codes from the inter-
nal register (which is separate from the memory array)
on DQ7DQ0. Standard read cycle timings apply in this
mode. Refer to the "Autoselect Mode" and "Autoselect
Command Sequence" sections for more information.
I
CC2
in the DC Characteristics table represents the ac-
tive 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 DQ7DQ0. Standard read cycle timings and I
CC
read specifications apply. Refer to "Write Operation
Status" for more information, and to each AC Charac-
teristics section in the appropriate data sheet 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, inde-
pendent of the OE# input.
The device enters the CMOS standby mode when the
CE# pin is held at V
CC
0.5 V. (Note that this is a more
restricted voltage range than V
IH
.) The device enters
the TTL standby mode when CE# is held at V
IH
. The
device requires the standard access time (t
CE
) before
it is ready to read data.
If the device is deselected during erasure or program-
ming, the device draws active current until the
operation is completed.
I
CC3
in the DC Characteristics tables represents the
standby current specification.
Output Disable Mode
When the OE# input is at V
IH
, output from the device is
disabled. The output pins are placed in the high imped-
ance state.
Table 2.
Am29F010 Sector Addresses Table
Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7DQ0. 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 V
ID
(11.5 V 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 ad-
dition, when verifying sector protection, the sector ad-
dress must appear on the appropriate highest order
address bits. Refer to the corresponding Sector Ad-
dress 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 program-
ming equipment may then read the corresponding
identifier code on DQ7DQ0.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in the Command Defini-
tions table. This method does not require V
ID
. See
"Command Definitions" for details on using the autose-
lect mode.

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 pro-
tected sectors.
Sector protection/unprotection must be implemented
using programming equipment. The procedure re-
quires a high voltage (V
ID
) on address pin A9 and the
control pins. Details on this method are provided in a
supplement, publication number 20495. Contact an
AMD representative to obtain a copy of the appropriate
document.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sectors at its factory prior to shipping the device
through AMD's ExpressFlashTM Service. Contact an
AMD representative for details.
It is possible to determine whether a sector is protected
or unprotected. See "Autoselect Mode" for details.
Hardware Data Protection
The command sequence requirement of unlock cycles
for programming or erasing provides data protection
against inadvertent writes (refer to the Command Defi-
nitions table). In addition, the following hardware data
protection measures prevent accidental erasure or pro-
gramming, which might otherwise be caused by spuri-
ous system level signals during V
CC
power-up and
power-down transitions, or from system noise.
Low V
CC
Write Inhibit
When V
CC
is less than V
LKO
, the device does not ac-
cept any write cycles. This protects data during V
CC
power-up and power-down. The command register and
all internal program/erase circuits are disabled, and the
device resets. Subsequent writes are ignored until V
CC
is greater than V
LKO
. The system must provide the
proper signals to the control pins to prevent uninten-
tional writes when V
CC
is greater than V
LKO
.
Write Pulse "Glitch" Protection
Noise pulses of less than 5 ns (typical) on OE#, CE# or
WE# do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by holding any one of OE#
= V
IL
, CE# = V
IH
or WE# = V
IH
. To initiate a write cy-
cle, CE# and WE# must be a logical zero while OE#
is a logical one.
Power-Up Write Inhibit
If WE# = CE# = V
IL
and OE# = V
IH
during power
up, the device does not accept commands on the
rising edge of WE#. The internal state machine is
a u t o m a t i c a l l y r e s e t t o r e a d i n g a r r a y d a t a o n

COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
erations. The Command Definitions table defines the
valid register command sequences. Writing incorrect
address and data values
or writing them in the im-
proper 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.
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 Em-
bedded Erase algorithm.
The system
must issue the reset command to re-en-
able the device for reading array data if DQ5 goes high,
or while in the autoselect mode. See the "Reset Com-
mand" 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 parame-
ters, and Read Operation Timings diagram shows the
timing diagram.
Reset Command
Writing the reset command to the device resets the de-
vice to reading array data. Address bits are don't care
for this command.
The reset command may be written between the se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to reading array
data. Once erasure begins, however, the device ig-
nores reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in a program command sequence be-
fore programming begins. This resets the device to
reading array data. Once programming begins, how-
ever, the device ignores reset commands until the op-
eration is complete.
The reset command may be written between the se-
quence cycles in an autoselect command sequence.
Once in the autoselect mode, the reset command must
be written to return to reading array data.
If DQ5 goes high during a program or erase operation,
writing the reset command returns the device to read-
ing array data.
Autoselect Command Sequence
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 program-
mers and requires V
ID
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 or retrieves the manu-
facturer code. A read cycle at address XX01h returns
the device code. A read cycle containing a sector ad-
dress (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.
The system must write the reset command to exit the
autoselect mode and return to reading array data.
Byte Program Command Sequence
Programming is a four-bus-cycle operation. The pro-
gram command sequence is initiated by writing two un-
lock write cycles, followed by the program set-up
command. The program address and data are written
next, which in turn initiate the Embedded Program al-
gorithm. The system is
not required to provide further
controls or timings. The device automatically provides
internally generated program pulses and verify the pro-
grammed cell margin. The Command Definitions take
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 ad-
dresses are no longer latched. The system can deter-
mine the status of the program operation by using
DQ7or DQ6. See "Write Operation Status" for informa-
tion on these status bits.
Any commands written to the device during the Em-
bedded 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 DQ5 to "1", or cause the Data#
Polling algorithm to indicate the operation was suc-
cessful. However, a succeeding read will show that the
data is still "0". Only erase operations can convert a "0"
to a "1".

Note: See the appropriate Command Definitions table for
program command sequence.
Figure 1.
Program Operation
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 algo-
rithm 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 con-
trols or timings during these operations. The Command
Definitions table shows the address and data require-
ments for the chip erase command sequence.
Any commands written to the chip during the Embed-
ded Erase algorithm are ignored.
The system can determine the status of the erase
operation by using DQ7 or DQ6. See "Write Opera-
tion Status" for information on these status bits.
When the Embedded Erase algorithm is complete,
the device returns to reading array data and ad-
dresses are no longer latched.
Figure 2 illustrates the algorithm for the erase opera-
tion. See the Erase/Program Operations tables in "AC
Characteristics" for parameters, and to the Chip/Sector
Erase Operation Timings for timing waveforms.
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 ad-
ditional unlock write cycles are then followed by the ad-
dress 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 algo-
rithm 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 tim-
ings during these operations.
After the command sequence is written, a sector erase
time-out of 50
s begins. During the time-out period,
additional sector addresses and sector erase com-
mands may be written. Loading the sector erase buffer
may be done in any sequence, and the number of sec-
tors may be from one sector to all sectors. The time be-
tween these additional cycles must be less than 50
s,
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 50
s, the
system need not monitor DQ3. Any command during
the time-out period resets the device to reading
array data.
The system must rewrite the command se-
quence and any additional sector addresses and com-
mands.
The system can monitor DQ3 to determine if the sector
erase timer has timed out. (See the "DQ3: Sector
Erase Timer" section.) The time-out begins from the ris-
ing edge of the final WE# pulse in the command se-
quence.
Once the sector erase operation has begun, 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 sta-
tus of the erase operation by using DQ7 or DQ6. Refer
to "Write Operation Status" for information on these
status bits.
Figure 2 illustrates the algorithm for the erase opera-
tion. 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.

WRITE OPERATION STATUS
The device provides several bits to determine the sta-
tus of a write operation: DQ3, DQ5, DQ6, and DQ7.
Table 5 and the following subsections describe the
functions of these bits. DQ7 and DQ6 each offer a
method for determining whether a program or erase
operation is complete or in progress. These three bits
are discussed first.
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host
sy ste m w h et he r a n E m b ed d ed A l go r it hm is i n
progress or completed. 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 DQ7 the complement of the datum pro-
grammed to DQ7. When the Embedded Program algo-
rithm is complete, the device outputs the datum
programmed to DQ7. The system must provide the
program address to read valid status information on
DQ7. If a program address falls within a protected sec-
tor, Data# Polling on DQ7 is active for approximately 2
s, then the device returns to reading array data.
During the Embedded Erase algorithm, Data# Polling
produces a "0" on DQ7. When the Embedded Erase al-
gorithm is complete, Data# Polling produces a "1" on
DQ7. 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 in-
formation on DQ7.
After an erase command sequence is written, if all sec-
tors selected for erasing are protected, Data# Polling
on DQ7 is active for approximately 100
s, then the de-
vice returns to reading array data. If not all selected
sectors are protected, the Embedded Erase algorithm
erases the unprotected sectors, and ignores the se-
lected sectors that are protected.
When the system detects DQ7 has changed from the
complement to true data, it can read valid data at DQ7
DQ0 on the following read cycles. This is because DQ7
may change asynchronously with DQ0DQ6 while
Output Enable (OE#) is asserted low. The Data# Poll-
ing Timings (During Embedded Algorithms) figure in
the "AC Characteristics" section illustrates this.
Table 5 shows the outputs for Data# Polling on DQ7.
Figure 3 shows the Data# Polling algorithm.

Notes:
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. DQ7 should be rechecked even if DQ5 = "1" because
DQ7 may change simultaneously with DQ5.

Data# Polling Algorithm

DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded
Program or Erase algorithm is in progress or complete.
Toggle Bit I may be read at any address, and is valid
after the rising edge of the final WE# pulse in the com-
mand sequence (prior to the program or erase opera-
tion), and during the sector erase time-out.
During an Embedded Program or Erase algorithm op-
eration, successive read cycles to any address cause
DQ6 to toggle. (The system may use either OE# or
CE# to control the read cycles.) When the operation is
complete, DQ6 stops toggling.
After an erase command sequence is written, if all
sectors selected for erasing are protected, DQ6 tog-
gles for approximately 100
s, then returns to reading
array data. If not all selected sectors are protected,
the Embedded Erase algorithm erases the unpro-
tected sectors, and ignores the selected sectors that
are protected.
If a program address falls within a protected sector,
DQ6 toggles for approximately 2
s after the program
command sequence is written, then returns to reading
array data.
The Write Operation Status table shows the outputs for
Toggle Bit I on DQ6. 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.
Reading Toggle Bit DQ6
Refer to Figure 4 for the following discussion. When-
ever the system initially begins reading toggle bit sta-
tus, it must read DQ7DQ0 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 sys-
tem 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 DQ7DQ0 on the fol-
lowing 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 DQ5 is
high (see the section on DQ5). If it is, the system
should then determine again whether the toggle bit is
toggling, since the toggle bit may have stopped tog-
gling just as DQ5 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 de-
termines that the toggle bit is toggling and DQ5 has not
gone high. The system may continue to monitor the
toggle bit and DQ5 through successive read cycles, de-
termining the status as described in the previous para-
graph. 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).

DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has
exceeded a specified internal pulse count limit. Under
these conditions DQ5 produces a "1." This is a failure
condition that indicates the program or erase cycle was
not successfully completed.
The DQ5 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, DQ5 produces a "1."
Under both these conditions, the system must issue
the reset command to return the device to reading
array data.
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the
system may read DQ3 to determine whether or not an
erase operation has begun. (The sector erase timer
does not apply to the chip erase command.) If addi-
tional sectors are selected for erasure, the entire time-
out also applies after each additional sector erase
command. When the time-out is complete, DQ3
switches from "0" to "1." The system may ignore DQ3
if the system can guarantee that the time between ad-
ditional sector erase commands will always be less
than 50
s. See also the "Sector Erase Command Se-
quence" section.
After the sector erase command sequence is written,
the system should read the status on DQ7 (Data# Poll-
ing) or DQ6 (Toggle Bit I) to ensure the device has ac-
cepted the command sequence, and then read DQ3. If
DQ3 is "1", the internally controlled erase cycle has be-
gun; all further commands are ignored until the erase
operation is complete. If DQ3 is "0", the device will ac-
cept additional sector erase commands. To ensure the
command has been accepted, the system software
should check the status of DQ3 prior to and following
each subsequent sector erase command. If DQ3 is
high on the second status check, the last command
might not have been accepted. Table 5 shows the out-
puts for DQ3.
Table 5.
Write Operation Status
Notes:
1. DQ7 requires a valid address when reading status information. Refer to the appropriate subsection for further details.
2. DQ5 switches to `1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits.
See "DQ5: Exceeded Timing Limits" for more information.

ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25
C, 5.0 V V
CC
, 100,000 cycles. Additionally,
programming typicals assume checkerboard pattern.
2. Under worst case conditions of 90C, V
CC
= 4.5 V (4.75 V for -45, -55 PDIP), 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 DQ5 = 1. See the section on DQ5 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 1
for further information on command definitions.
6. The device has a typical erase and program cycle endurance of 1,000,000 cycles. 100,000 cycles are guaranteed.
