GENERAL DESCRIPTION
The Am29LV065MU is a 64 Mbit, 3.0 volt single power
supply flash memory devices organized as 8,388,608
bytes. The device has an 8-bit wide data bus, and can
be programmed either in the host system or in standard EPROM programmers.
An access time of 90, 100, 110, or 120 ns is available.
Note that each device has a specific operating voltage
range (VCC) and an I/O voltage range (VIO), as specified in “Product Selector Guide” on page 5 and “Ordering Information” on page 9. The device is offered in a
48-pin TSOP or 63-ball FBGA package. Each device
has separate chip enable (CE#), write enable (WE#)
and output enable (OE#) controls.
Each device requires only a single 3.0 volt power
supply for both read and write functions. In addition to
a V CC input, a high-voltage accelerated program
(ACC) input provides shorter programming times
through increased current. This feature is intended to
facilitate factory throughput during system production,
but may also be used in the field if desired.
The device is entirely command set compatible with
the JEDEC single-power-supply Flash standard.
Commands are written to the device using standard
microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations.
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.
Device programming and erasure are initiated through
command sequences. Once a program or erase operation has begun, the host system need only poll the
DQ7 (Data# Polling) or DQ6 (toggle) status bits or
monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate
programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write
cycles to program data instead of four.
and tolerates on the CE# control input and DQ I/Os to
the same voltage level that is asserted on the VIO pin.
See “Ordering Information” on page 9. for valid VIO options.
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 sectors of memory.
This can be achieved in-system or via programming
equipment.
The Erase Suspend/Erase Resume feature allows
the host system to pause an erase operation in a given
sector to read or program any other sector and then
complete the erase operation. The Program Suspend/Program Resume feature enables the host system to pause a program operation in a given sector to
read any other sector and then complete the program
operation.
The hardware RESET# pin terminates any operation
in progress and resets the device, after which it is then
ready for a new operation. The RESET# pin may be
tied to the system reset circuitry. A system reset would
thus also reset the device, enabling the host system to
read boot-up firmware from the Flash memory device.
The device reduces power consumption in the
standby mode when it detects specific voltage levels
on CE# and RESET#, or when addresses have been
stable for a specified period of time.
The SecSi™ (Secured Silicon) Sector provides a 256
byte area for code or data that can be permanently
protected. Once this sector is protected, no further
changes within the sector can occur.
AMD MirrorBit flash technology combines years of
Flash memory manufacturing experience to produce
the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a
sector simultaneously via hot-hole assisted erase. The
data is programmed using hot electron injection.
The VersatileI/O™ (VIO) control allows the host system to set the voltage levels that the device generates

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 a latch used to store the commands, along with the address and data information
needed to execute the command. The contents of the
Table 1.
register serve as inputs to the internal state machine.
The state machine outputs dictate the function of the
device. Table 1 lists the device bus operations, the inputs and control levels they require, and the resulting
output. The following subsections describe each of
these operations in further detail.

VersatileIO™ (VIO) Control
The VersatileIO™ (VIO) control allows the host system
to set the voltage levels that the device generates and
tolerates on CE# and DQ I/Os to the same voltage
level that is asserted on VIO. See “Ordering Information” on page 9. for VIO options on this device.
For example, a VI/O of 1.65–3.6 volts allows for I/O at
the 1.8 or 3 volt levels, driving and receiving signals to
and from other 1.8 or 3 V devices on the same data
bus.
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 con-
10
trol and gates array data to the output pins. WE#
should remain at VIH.
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” on page 25. for more information. “Read-Only Operations” on page 42 for timing
specifications and to Figure 13 for the timing diagram.

See the table, “DC Characteristics” on page 40 for the
active current specification for reading array data.
Page Mode Read
The device is capable of fast page mode read and is
compatible with the page mode Mask ROM read operation. This mode provides faster read access speed
for random locations within a page. The page size of
the device is 8 bytes. The appropriate page is selected
by the higher address bits A(max)–A3. Address bits
A2–A0 determine the specific byte within a page. This
is an asynchronous operation; the microprocessor
supplies the specific byte location.
The random or initial page access is equal to tACC or
tCE and subsequent page read accesses (as long as
the locations specified by the microprocessor falls
within that page) is equivalent to tPACC. When CE# is
deasserted and reasserted for a subsequent access,
the access time is t ACC or t CE . Fast page mode accesses are obtained by keeping the “read-page addresses” constant and changing the “intra-read page”
addresses.
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.
The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the
Unlock Bypass mode, only two write cycles are required to program a byte, instead of four. The “Byte
Program Command Sequence” on page 26 has details on programming data to the device using both
standard and Unlock Bypass command sequences.
An erase operation can erase one sector, multiple sectors, or the entire device. Table 2 indicates the address
space that each sector occupies.
See the table, “DC Characteristics” on page 40 for the
active current specification for the write mode. “AC
Characteristics” on page 42 contains timing specification tables and timing diagrams for write operations.
Write Buffer
Write Buffer Programming allows the system to write a
maximum of 32 bytes in one programming operation.
This results in faster effective programming time than
the standard programming algorithms. See “Write
Buffer” for more information.
Accelerated Program Operation
The device offers accelerated program operations
through the ACC function. This function is primarily intended to allow faster manufacturing throughput during system production.
September 12, 2006
S H E E T
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 ACC pin returns the device to normal operation. Note that the ACC pin must not be at VHH for
operations other than accelerated programming, or
device damage may result. In addition, the ACC pin
must not be left floating or unconnected; inconsistent
behavior of the device may result.
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 DQ7–DQ0. Standard read cycle timings apply in
this mode. See “Autoselect Mode” on page 17. and
“Autoselect Command Sequence” on page 26 for
more information.
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# and RESET# pins are both held at VIO ± 0.3 V.
(Note that this is a more restricted voltage range than
VIH.) If CE# and RESET# are held at VIH, but not within
VIO ± 0.3 V, the device will be in the standby mode, but
the standby current will be greater. The device requires standard access time (t CE ) 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.
See the table, “DC Characteristics” on page 40 for 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 +
30 ns. The automatic 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.

memory, enabling the system to read the boot-up firmware from the Flash memory.
RESET#: Hardware Reset Pin
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the
internal reset operation is complete, which requires a
time of 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 operation is not executing
(RY/BY# pin is “1”), the reset operation is completed
within a time of t READY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH.
The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the
device immediately terminates any operation in
progress, tristates all output pins, and ignores all
read/write commands 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±0.3 V, the device
draws CMOS standby current. If RESET# is held at VIL
but not within VSS±0.3 V, the standby current will be
greater.
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash
12
See the tables in “AC Characteristics” on page 42 for
RESET# parameters and to Figure 15 for the timing 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
In addition, when verifying sector protection, the sector
address must appear on the appropriate highest order
address bits (see Table 2). Table 3 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 DQ7–DQ0.
The autoselect mode provides manufacturer and device identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. 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.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in Table 10. This method
does not require VID. See “Autoselect Command Sequence” on page 26. for more information.
When using programming equipment, the autoselect
mode requires VID on address pin A9. Address pins
A6, A3, A2, A1, and A0 must be as shown in Table 3.

Table 4.
Sector Group Protection/Unprotection
Address Table
The hardware sector group protection feature disables
both program and erase operations in any sector
group. In this device, a sector group consists of four
adjacent sectors that are protected or unprotected at
the same time (see Table 4). The hardware sector
group unprotection feature re-enables both program
and erase operations in previously protected sector
groups. Sector group protection/unprotection can be
implemented via two methods.
Sector Group
A22–A18
SA0–SA3
00000
Sector protection/unprotection 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 group unprotect, all unprotected sector groups must first be protected prior to
the first sector group unprotect write cycle.
The device is shipped with all sector groups unprotected. AMD offers the option of programming and protecting sector groups at its factory prior to shipping the
device through AMD’s ExpressFlash™ Service. Contact an AMD representative for details.
It is possible to determine whether a sector group is
protected or unprotected. See “Autoselect Mode” on
page 17. for details.

START
This feature allows temporary unprotection of previously protected sector groups to change data in-system. The Sector Group Unprotect mode is activated by
setting the RESET# pin to VID. During this mode, formerly protected sector groups can be programmed or
erased by selecting the sector group addresses. Once
VID is removed from the RESET# pin, all the previously
protected sector groups are protected again. Figure 1
shows the algorithm, and Figure 22 shows the timing

SecSi (Secured Silicon) Sector Flash
Memory Region
Factory Locked: SecSi Sector Programmed and
Protected At the Factory
The SecSi (Secured Silicon) Sector feature provides a
Flash memory region that enables permanent part
identification through an Electronic Serial Number
(ESN). The SecSi Sector is 256 bytes in length, and
uses a SecSi Sector Indicator Bit (DQ7) to indicate
whether or not the SecSi Sector is locked when
shipped from the factory. This bit is permanently set at
the factory and cannot be changed, which prevents
cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field.
In devices with an ESN, the SecSi Sector is protected
when the device is shipped from the factory. The SecSi
Sector cannot be modified in any way. A factory locked
device has an 16-byte random ESN at addresses
000000h–00000Fh.
AMD offers the device with the SecSi Sector either
facto r y locked or c ustomer lock able. The factory-locked version is always protected when shipped
from the factory, and has the SecSi (Secured Silicon)
Sector Indicator Bit permanently set to a “1.” The customer-lockable version is shipped with the SecSi Sector unprotected, allowing customers to program the
sector after receiving the device. The customer-lockable version also has the SecSi Sector Indicator Bit
permanently set to a “0.” Thus, the SecSi Sector Indicator Bit prevents customer-lockable devices from
being used to replace devices that are factory locked.
The SecSi sector address space in this device is allocated as follows:

As an alternative to the factory-locked version, the device may be ordered such that the customer may program and protect the 256-byte SecSi sector.
The system may program the SecSi Sector using the
write-buffer, accelerated and/or unlock bypass methods, in addition to the standard programming command sequence. See “Command Definitions” on
page 25..
Customer
Lockable
Determined by
customer
The SecSi Sector area can be protected using one of
the following procedures:
The system accesses the SecSi Sector through a
command sequence (see “Enter SecSi Sector/Exit
SecSi Sector Command Sequence”). After the system
has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the first sector (SA0).
This mode of operation continues until the system issues the Exit SecSi Sector command sequence, or
until power is removed from the device. On power-up,
or following a hardware reset, the device reverts to
sending commands to sector SA0. Note that the ACC
function and unlock bypass modes are not available
when the SecSi Sector is enabled.
September 12, 2006
Customer Lockable: SecSi Sector NOT
Programmed or Protected At the Factory
Programming and protecting the SecSi Sector must be
used with caution since, once protected, there is no
procedure available for unprotecting the SecSi Sector
area and none of the bits in the SecSi Sector memory
space can be modified in any way.
SecSi Sector Contents

Customers may opt to have their code programmed by
AMD through the AMD ExpressFlash service. The devices are then shipped from AMD’s factory with the
SecSi Sector permanently locked. Contact an AMD
representative for details on using AMD’s ExpressFlash service.
■ Write the three-cycle Enter SecSi Sector Region
command sequence, and then follow the in-system
sector protect algorithm as shown in Figure 2, except that RESET# may be at either VIH or VID. This
allows in-system protection of the SecSi Sector
without raising any device pin to a high voltage.
Note that this method is only applicable to the SecSi
Sector.
■ To verify the protect/unprotect status of the SecSi
Sector, follow the algorithm shown in Figure 3.
Once the SecSi Sector is programmed, locked and
verified, the system must write the Exit SecSi Sector
Region command sequence to return to reading and
writing within the remainder of the array.

When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC

and the device resets to the read mode. Subsequent
writes are ignored until VCC is greater than VLKO. The

Hardware Data Protection
The command sequence requirement of unlock cycles

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, any time the device is ready to read array data.
The system can read CFI information at the addresses
given in Tables 6–9. To terminate reading CFI data,
the system must write the reset command.
22
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 6–9. The
system must write the reset command to return the
device to reading array data.
For further information, please refer to the CFI Specification and CFI Publication 100, available via the World
Wide Web at http://www.amd.com/flash/cfi. Alternatively, contact an AMD representative for copies of

COMMAND DEFINITIONS
Writing specific address and data commands or sequences into the command register initiates device operations. Table 10 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.
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 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-read mode, after
which the system can read data from any
Am29LV065MU
25
D A T A
non-erase-suspended sector. 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” on page 32. for more information.
The system must issue the reset command to return
the device to the read (or erase-suspend-read) mode if
DQ5 goes high during an active program or erase operation, or if the device is in the autoselect mode. See
the next section, Reset Command, for more information.
See “Requirements for Reading Array Data” on
page 10. for more infor mation. See the table,
“Read-Only Operations” on page 42 provides the read
parameters, and Figure 13 shows the timing diagram.
Reset Command
Writing the reset command resets the device 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 device to the read
mode. 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
the read mode. If the program command sequence is
written while the device is in the Erase Suspend mode,
writing the reset command returns the device 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 the read mode. If the device entered the autoselect mode while in the Erase
Suspend mode, writing the reset command returns the
device to the erase-suspend-read mode.
If DQ5 goes high during a program or erase operation,
writing the reset command returns the device to the
read mode (or erase-suspend-read mode if the device
was in Erase Suspend).
Note that if DQ1 goes high during a Write Buffer Programming operation, the system must write the
Write-to-Buffer-Abort Reset command sequence to
reset the device for the next operation.
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.
26
S H E E T
Table 10 shows the address and data requirements.
This method is an alternative to that shown in Table 3,
which is intended for PROM programmers and requires V ID on address pin A9. The autoselect command sequence may be written to an address that is
either in the read or erase-suspend-read mode. The
autoselect command may not be written while the device is actively programming or erasing.
The autoselect command sequence is initiated by first
writing two unlock cycles. This is followed by a third
write cycle that contains the autoselect command. The
device then enters the autoselect mode. The system
may read at any address any number of times without
initiating another autoselect command sequence:
■ A read cycle at address XX00h returns the manufacturer code.
■ Three read cycles at addresses 01h, 0Eh, and 0Fh
return the device code.
■ A read cycle to an address containing a sector
group address (SA), and the address 02h on A7–A0
returns 01h if the sector group is protected, or 00h
if it is unprotected. (See Table 4 for valid sector addresses).
The system must write the reset command to return to
the read mode (or erase-suspend-read mode if the device was previously in Erase Suspend).
Enter SecSi Sector/Exit SecSi Sector
Command Sequence
The SecSi Sector region provides a secured data area
containing an 16-byte random Electronic Serial Number (ESN). The system can access the SecSi Sector
region by issuing the three-cycle Enter SecSi Sector
command sequence. The device continues to access
the SecSi Sector region until the system issues the
four-cycle Exit SecSi Sector command sequence. The
Exit SecSi Sector command sequence returns the device to normal operation. Table 10 shows the address
and data requirements for both command sequences.
See also “SecSi (Secured Silicon) Sector Flash
Memory Region” for further information. Note that the
ACC function and unlock bypass modes are not available when the SecSi Sector is enabled.
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 verifies the
programmed cell margin. Table 10 shows the address
Am29LV065MU
September 12, 2006
D A T A
and data requirements for the byte program command
sequence.
When the Embedded Program algorithm is complete,
the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using
DQ7, DQ6, or RY/BY#. See “Write Operation Status”
on page 35. 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 the device has returned to the read
mode, to ensure data integrity. Note that the SecSi
Sector, autoselect, and CFI functions are unavailable
when a program operation is in progress.
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 the device to set DQ5 = 1, or cause the DQ7
and DQ6 status bits to indicate the operation was successful. However, a succeeding read will show that the
data is still “0.” Only erase operations can convert a “0”
to a “1.”
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to program bytes to the device faster than using the standard program command sequence. The unlock bypass
command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device
then enters the unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is
required to program in this mode. The first cycle in this
sequence contains the unlock bypass program command, A0h; the second cycle contains the program
address and data. Additional data is programmed in
the same manner. This mode dispenses with the initial
two unlock cycles required in the standard program
command sequence, resulting in faster total programming time. Table 10 shows the requirements for the
command sequence.
During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data
90h. The second cycle must contain the data 00h. The
device then returns to the read mode.
Write Buffer Programming
Write buffer programming allows the system to write a
maximum of 32 bytes in one programming operation.
The effective programming time is faster than the stan-
September 12, 2006
S H E E T
dard programming algorithms. The write buffer programming command sequence is initiated by first
writing two unlock cycles. This is followed by a third
write cycle containing the Write Buffer Load command
written at the Sector Address in which programming
will occur. The fourth cycle writes the sector address
and the number of byte locations, minus one, to be
programmed. For example, if the system will program
6 unique address locations, then 05h should be written
to the device. This tells the device how many write
buffer addresses will be loaded with data and therefore
when to expect the Program Buffer to Flash command.
The number of locations to program cannot exceed
the size of the write buffer or the operation will abort.
The fifth cycle writes the first address location and
data to be programmed. A write-buffer-page is selected by address bits AMAX–A5. All subsequent add r e s s / d a t a p a i r s m u s t fa l l w i t h i n t h e
selected-write-buffer-page. The system then writes the
remaining address/data pairs into the write buffer.
Write buffer locations may be loaded in any order.
The write-buffer-page address must be the same for
all address/data pairs loaded into the write buffer. That
is, write buffer programming cannot occur across multiple write-buffer pages or sectors. If the system attempts to load programming data outside of the
selected write-buffer page, the operation will abort.
Note that if a Write Buffer address location is loaded
multiple times, the address/data pair counter will be
decremented for every data load operation. The host
s y s t e m m u s t t h e r e fo r e a c c o u n t fo r l o a d i n g a
write-buffer location more than once. The counter decrements for each data load operation, not for each
unique write-buffer-address location. Additionally, the
last data loaded prior to the Program Buffer to Flash
command will be programmed into the device. Note
also that if an address location is loaded more than
once into the buffer, the final data loaded for that address will be programmed.
Once the specified number of write buffer locations
have been loaded, the system must then write the Program Buffer to Flash command at the sector address.
Any other address and data combination aborts the
Write Buffer Programming operation. The device then
begins programming. Data polling should be used
while monitoring the last address location loaded into
the write buffer. DQ7, DQ6, DQ5, and DQ1 should be
monitored to determine the device status during Write
Buffer Programming.
The write-buffer programming operation can be suspended using the standard program suspend/resume
commands. Upon successful completion of the Write
Buffer Programming operation, the device is ready to
execute the next command.

The Write Buffer Programming Sequence can be
aborted in the following ways:
■ Load a value that is greater than the page buffer
size during the Number of Locations to Program
step.
■ Write to an address in a sector different than the
one specified during the Write-Buffer-Load command.
■ Write an Address/Data pair to a different
write-buffer-page than the one selected by the
Starting Address during the write buffer data loading stage of the operation.
■ Write data other than the Confirm Command after
the specified number of data load cycles.
The abort condition is indicated by DQ1 = 1, DQ7 =
DATA# (for the last address location loaded), DQ6 =
toggle, and DQ5=0. A Write-to-Buffer-Abort Reset
command sequence must be written to reset the device for the next operation. Note that the full 3-cycle

in Unlock Bypass mode.
Accelerated Program
The device offers accelerated program operations
through the ACC pin. When the system asserts VHH on
the 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
ACC pin to accelerate the operation. Note that the
ACC pin must not be at VHH for operations other than
accelerated programming, or device damage may result. In addition, the ACC pin must not be left floating
or unconnected; inconsistent behavior of the device
may result.
Figure 4 illustrates the algorithm for the program operation. See the table, “Erase and Program Operations”

Program Suspend/Program Resume
Command Sequence
The Program Suspend command allows the system to
interrupt a programming operation or a Write to Buffer
programming operation so that data can be read from
any non-suspended sector. When the Program Suspend command is written during a programming process, the device halts the program operation within
15 μs maximum (5 μs typical) and updates the status
bits. Addresses are not required when writing the Program Suspend command.

After the programming operation has been suspended, the system can read array data from any
non-suspended sector. The Program Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data
may be read from any addresses not in Erase Suspend or Program Suspend. If a read is needed from
the SecSi Sector area (One-time Program area), then
user must use the proper command sequences to
enter and exit this region.
The system may also write the autoselect command
sequence when the device is in the Program Suspend
mode. The system can read as many autoselect codes
as required. When the device exits the autoselect
mode, the device reverts to the Program Suspend
mode, and is ready for another valid operation. See
“Autoselect Command Sequence” on page 26. for
more information.
After the Program Resume command is written, the
device reverts to programming. The system can determine the status of the program operation using the
DQ7 or DQ6 status bits, just as in the standard program operation. See “Write Operation Status” on
page 35. for more information.
The system must write the Program Resume command (address bits are don’t care) to exit the Program
Suspend mode and continue the programming operation. Further writes of the Resume command are ignored. Another Program Suspend command can be
written after the device has resume programming.

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 10
shows the address and data requirements for the chip
erase command sequence.
September 12, 2006
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 the device has returned to reading
array data, to ensure data integrity.
Figure 6 illustrates the algorithm for the erase operation. See the table, “Erase and Program Operations”
on page 45 for parameters, and Figure 18 section for
timing diagrams.

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 10 shows the address and data requirements for the sector erase command sequence.
The device does not require the system to preprogram
prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for
an all zero data pattern prior to electrical erase. The
system is not required to provide any controls or timings during these operations.
After the command sequence is written, a sector erase
time-out of 50 µs occurs. During the time-out period,
additional sector addresses and sector erase commands 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 50
µs, 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
the device to the read mode. The system must rewrite the command sequence and any additional addresses and commands. Note that the SecSi Sector,
autoselect, and CFI functions are unavailable when an
erase operation is in progress.
Am29LV065MU
31
D A T A
The system can monitor DQ3 to determine if the sector erase timer has timed out (See “DQ3: Sector Erase
Timer” on page 37..). The time-out begins from the rising edge of the final WE# pulse in the command
sequence.
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 reading DQ7, DQ6,
DQ2, or RY/BY# in the erasing sector. See “Write Operation Status” on page 35. 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 the device has returned to
reading array data, to ensure data integrity.
Figure 6 illustrates the algorithm for the erase operation. See the tables, “Erase and Program Operations”
on page 45 for parameters, and Figure 18 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 typical of 5 µs (maximum 20 μs) to suspend the erase operation. However, when the Erase Suspend command
is written during the sector erase time-out, the device
immediately terminates the time-out period and suspends the erase operation.
32
S H E E T
After the erase operation has been suspended, the
device 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 DQ7–DQ0. The system
can use DQ7, or DQ6 and DQ2 together, to determine
if a sector is actively erasing or is erase-suspended.
See “Write Operation Status” on page 35. for information on these status bits.
After an erase-suspended program operation is complete, the device returns to the erase-suspend-read
mode. The system can determine the status of the
program operation using the DQ7 or DQ6 status bits,
just as in the standard byte program operation. See
“Write Operation Status” on page 35. for more information.
In the erase-suspend-read mode, the system can also
issue the autoselect command sequence. See “Autoselect Mode” on page 17. and “Autoselect Command Sequence” on page 26 for details.
To resume the sector erase operation, the system
must write the Erase Resume command. Further
writes of the Resume command are ignored. Another
Erase Suspend command can be written after the chip
has resumed erasing.
Note: During an erase operation, this flash device performs multiple internal operations which are invisible
to the system. When an erase operation is suspended,
any of the internal operations that were not fully completed must be restarted. As such, if this flash device
is continually issued suspend/resume commands in
rapid succession, erase progress will be impeded as a
function of the number of suspends. The result will be
a longer cumulative erase time than without suspends.
Note that the additional suspends do not affect device
reliability or future performance. In most systems rapid
erase/suspend activity occurs only briefly. In such
cases, erase performance will not be significantly impacted.

WRITE OPERATION STATUS
The device provides several bits to determine the status of a
program or erase operation: DQ2, DQ3, DQ5, DQ6, and
DQ7. Table 11 and the following subsections describe the
function of these bits. DQ7 and DQ6 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.
valid data, the data outputs on DQ0–DQ6 may be still
invalid. Valid data on DQ0–DQ7 will appear on successive read cycles.
Table 11 shows the outputs for Data# Polling on DQ7.
Figure 7 shows the Data# Polling algorithm. Figure 19
in “AC Characteristics” shows the Data# Polling timing
diagram.
DQ7: Data# Polling
START
The Data# Polling bit, DQ7, indicates to the host system
whether an Embedded Program or Erase 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 command sequence.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to
DQ7. This DQ7 status also applies to programming during
Erase Suspend. When the Embedded Program algorithm 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 sector, Data# Polling on DQ7 is active for approximately 1 µs, then the device returns to the
read mode.
Read DQ7–DQ0
Addr = VA
DQ7 = Data?
No
No
During the Embedded Erase algorithm, Data# Polling
produces a “0” on DQ7. When the Embedded Erase
algorithm is complete, or if the device enters the Erase
Suspend mode, Data# Polling produces a “1” on DQ7.
The system must provide an address within any of the
sectors selected for erasure to read valid status information on DQ7.
After an erase command sequence is written, if all
sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately 100 µs, then the
device returns to the read mode. 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 DQ7 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, DQ7 may change asynchronously
with DQ0–DQ6 while Output Enable (OE#) is asserted
low. That is, the device may change from providing
status information to valid data on DQ7. Depending on
when the system samples the DQ7 output, it may read

RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin
which 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.

Table 11 shows the outputs for Toggle Bit I on DQ6.
Figure 8 shows the toggle bit algorithm. Figure 20 in
the AC Characteristics shows the toggle bit timing diagrams. Figure 21 shows the differences between DQ2
and DQ6 in graphical form. See “DQ2: Toggle Bit II” on
page 37..
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 in the read mode, the standby
mode, or the device is in the erase-suspend-read
mode.

DQ6: Toggle Bit I
Toggle Bit I on DQ6 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
DQ6 to toggle. The system may use either OE# or
CE# to control the read cycles. When the operation is
complete, DQ6 stops toggling.

If a program address falls within a protected sector,
DQ6 toggles for approximately 1 μs after the program
command sequence is written, then returns to reading
array data.

After an erase command sequence is written, if all sectors
selected for erasing are protected, DQ6 toggles for approximately 100 µs, 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 DQ6 and DQ2 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), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling.
However, the system must also use DQ2 to determine
which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (See “DQ7: Data# Polling”
on page 35.).

DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, 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.
DQ2 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 DQ2 cannot distinguish
whether the sector is actively erasing or is erase-suspended. DQ6, 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 11 to compare outputs for DQ2 and DQ6.
Figure 8 shows the toggle bit algorithm in flowchart
form, and “DQ2: Toggle Bit II” explains the algorithm.
Also, see “DQ6: Toggle Bit I” on page 36. Figure 20
shows the toggle bit timing diagram. Figure 21 shows
the differences between DQ2 and DQ6 in graphical
form.
Reading Toggle Bits DQ6/DQ2
Refer to Figure 8 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7–DQ0 at least twice in a row to
determine whether a toggle bit is toggling. Typically,
the 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 DQ7–DQ0 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 DQ5 is high
(See “DQ5: Exceeded Timing Limits” on page 37.). 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 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 completed 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 DQ5 has
not gone high. The system may continue to monitor
September 12, 2006
S H E E T
the toggle bit and DQ5 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 8).
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program, erase, or
write-to-buffer time has exceeded a specified internal
pulse count limit. Under these conditions DQ5 produces a
“1,” indicating that the program or erase cycle was not successfully completed.
The device may output a “1” on DQ5 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, DQ5 produces a “1.”
In all these cases, the system must write the reset
command to return the device to the reading the array
(or to erase-suspend-read if the device was previously
in the erase-suspend-program mode).
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the
system may read DQ3 to determine whether or not
erasure 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 period is complete, DQ3
switches from a “0” to a “1.” If the time between additional sector erase commands from the system can be
assumed to be less than 50 µs, the system need not
monitor DQ3. Also, see “Sector Erase Command Sequence” on page 31.
After the sector erase command is written, the system
should read the status of DQ7 (Data# Polling) or DQ6
(Toggle Bit I) to ensure that the device has accepted
the command sequence, and then read DQ3. If DQ3 is
“1,” the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored
until the erase operation is complete. If DQ3 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 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 11 shows the status of DQ3 relative to the other
status bits.

4. Effective write buffer specification is based upon a 32-byte write buffer operation.
5. Byte programming specification is based upon a single byte programming operation not utilizing the write buffer.
6. AC specifications listed are tested with VIO = VCC. Contact AMD for information on AC operation with VIO ≠ VCC.
7. When using the program suspend/resume feature, if the suspend command is issued within tPOLL, tPOLL must be fully re-applied
upon resuming the programming operation. If the suspend command is issued after tPOLL, tPOLL is not required again prior to
reading the status bits upon resuming.

Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0 V VCC, 100,000 cycles. Additionally,
programming typicals assume checkerboard pattern.
Under worst case conditions of 90°C, VCC = 3.0 V, 100,000 cycles.
Effective write buffer specification is based upon a 32–byte write buffer operation.
Byte programming specification is based upon a single byte programming operation not utilizing the write buffer.
In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table
10 for further information on command definitions.
7. The device has a minimum erase and program cycle endurance of 100,000 cycles.
