DATASHEET
GENERAL DESCRIPTION
The Am29LV128MH/L is a 128 Mbit, 3.0 volt single
power supply flash memory devices organized as
8,388,608 words or 16,777,216 bytes. The device has
a 16-bit wide data bus that can also function as an
8-bit wide data bus by using the BYTE# input. The de-
vice 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 access time has a specific operating
voltage range (VCC) and an I/O voltage range (VIO), as
specified in the Product Selector Guide and the Order-
ing Information sections. The device is offered in a
56-pin TSOP, 64-ball Fortified BGA. 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 VCC input, a high-voltage accelerated program
(WP#/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 inter-
nally latch addresses and data needed for the pro-
gramming and erase operations.
The sector erase architecture allows memory sec-
tors 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 oper-
ation 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 deter-
mine whether the operation is complete. To facilitate
programming, an Unlock Bypass mode reduces com-
mand sequence overhead by requiring only two write
cycles to program data instead of four.
The VersatileI/O™ (VIO) control allows the host sys-
tem to set the voltage levels that the device generates
and tolerates on the CE# control input and DQ I/Os to
the same voltage level that is asserted on the VIO pin.
Refer to the Ordering Information section for valid VIO
options.
Hardware data protection measures include a low
VCC detector that automatically inhibits write opera-
tions during power transitions. The hardware sector
group protection feature disables both program and
erase operations in any combination of sector groups
of memory. This can be achieved in-system or via pro-
gramming 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 Sus-
pend/Program Resume feature enables the host sys-
tem 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
128-word/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.
The Write Protect (WP#/ACC) feature protects the
first or last sector by asserting a logic low on the WP#
pin.
AMD MirrorBit flash technology combines years of
Flash memory manufacturing experience to produce
the highest levels of quality, reliability and cost effec-
tiveness. The device electrically erases all bits within a
sector simultaneously via hot-hole assisted erase. The
data is programmed using hot electron injection.

the internal command register. The command register
itself does not occupy any addressable memory loca-
tion. The register is a latch used to 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. Table 1 lists the device bus operations, the in-
puts and control levels they require, and the resulting
output. The following subsections describe each of
these operations in further detail.

Word/Byte Configuration
The BYTE# pin controls whether the device data I/O
pins operate in the byte or word configuration. If the
BYTE# pin is set at logic ‘1’, the device is in word con-
figuration, DQ0–DQ15 are active and controlled by
CE# and OE#.
If the BYTE# pin is set at logic ‘0’, the device is in byte
configuration, and only data I/O pins DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O
pins DQ8–DQ14 are tri-stated, and the DQ15 pin is
used as an input for the LSB (A-1) address function.
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
for VIO options on this device.

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-
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 com-
mand 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-Only Operations table for timing speci-
fications and to Figure 14 for the timing diagram. Refer
to the DC Characteristics table for the active current
specification on 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 oper-
ation. This mode provides faster read access speed
for random locations within a page. The page size of
the device is 4 words/8 bytes. The appropriate page is
selected by the higher address bits A(max)–A2. Ad-
dress bits A1–A0 in word mode (A1–A-1 in byte mode)
determine the specific word within a page. This is an
asynchronous operation; the microprocessor supplies
the specific word 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 tPA C C. When CE# is
deasserted and reasserted for a subsequent access,
the access time is tACC or tCE. Fast page mode ac-
cesses are obtained by keeping the “read-page ad-
dresses” constant and changing the “intra-read page”
addresses.
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 VIL, and OE# to VIH.
The device features an Unlock Bypass mode to facili-
tate faster programming. Once the device enters the
Unlock Bypass mode, only two write cycles are re-
quired to program a word or byte, instead of four. The
“Word/Byte Program Command Sequence” section
has details on programming data to the device using
both standard and Unlock Bypass command se-
quences.
An erase operation can erase one sector, multiple sec-
tors, or the entire device. Table 2 indicates the address
space that each sector occupies.
Refer to the DC Characteristics table for the active
current specification for the write mode. The AC Char-
acteristics section contains timing specification tables
and timing diagrams for write operations.
Write Buffer
Write Buffer Programming allows the system write to a
maximum of 16 words/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 is one of two functions
provided by the WP#/ACC pin. This function is prima-
rily intended to allow faster manufacturing throughput
at the factory.
If the system asserts VHH on this pin, the device auto-
matically enters the aforementioned Unlock Bypass
mode, temporarily unprotects any protected sector
groups, and uses the higher voltage on the pin to re-
duce the time required for program operations. The
system would use a two-cycle program command se-
quence as required by the Unlock Bypass mode. Re-
moving VHH from the WP#/ACC pin returns the device
to normal operation.
Note that the WP#/ACC pin must
not be at V
HH
for operations other than accelerated
programming, or device damage may result. WP# has
an internal pullup; when unconnected, WP# is at V
IH
.
Autoselect Functions
If 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 DQ7–DQ0. Standard read cycle timings apply in
this mode. Refer to the Autoselect Mode and Autose-
lect Command Sequence sections for more informa-
tion.
Standby Mode
When the system is not reading or writing to the de-
vice, 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
September 9, 2003 Am29LV128MH/L 11
DATASHEET
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 re-
quires standard access time (tCE) for read access
when the device is in either of these standby modes,
before it is ready to read data.
If the device is deselected during erasure or program-
ming, the device draws active current until the
operation is completed.
Refer to the DC Characteristics table for the standby
current specification.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device en-
ergy 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 ad-
dress access timings provide new data when ad-
dresses are changed. While in sleep mode, output
data is latched and always available to the system.
Refer to the DC Characteristics table for the automatic
sleep mode current specification.
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of re-
setting the device to reading array data. When the RE-
SET# 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 ma-
chine to reading array data. The operation that was in-
terrupted should be reinitiated once the device is
ready to accept another command sequence, to en-
sure 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 (ICC4). 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 cir-
cuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firm-
ware from the Flash memory.
Refer to the AC Characteristics tables for RESET# pa-
rameters and to Figure 16 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.

DATASHEET
Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector group protection verifica-
tion, through identifier codes output on DQ7–DQ0.
This mode is primarily intended for programming
equipment to automatically match a device to be pro-
grammed with its corresponding programming algo-
rithm. However, the autoselect codes can also be
accessed in-system through the command register.
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.
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 remain-
ing address bits that are don’t care. When all neces-
sary bits have been set as required, the programming
equipment may then read the corresponding identifier
code on DQ7–DQ0.
To access the autoselect codes in-system, the host
system can issue the autoselect command via the
command register, as shown in Tables 10 and 11. This
method does not require VID. Refer to the Autoselect
Command Sequence section for more information.

DATASHEET
Sector Group Protection and Unprotection
The hardware sector group protection feature disables
both program and erase operations in any sector
group. The hardware sector group unprotection fea-
ture re-enables both program and erase operations in
previously protected sector groups. Sector group pro-
tection/unprotection can be implemented via two
methods.
Sector group 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 25 shows the timing
diagram. This method uses standard microprocessor
bus cycle timing. For sector group unprotect, all unpro-
tected sector group must first be protected prior to the
first sector group unprotect write cycle.
The device is shipped with all sector groups unpro-
tected. AMD offers the option of programming and pro-
tecting sector groups at its factory prior to shipping the
device through AMD’s ExpressFlash™ Service. Con-
tact an AMD representative for details.
It is possible to determine whether a sector group is
protected or unprotected. See the Autoselect Mode
section for details.

Write Protect (WP#)
The Write Protect function provides a hardware
method of protecting the first or last sector group with-
out using VID. Write Protect is one of two functions pro-
vided by the WP#/ACC input.
If the system asserts VIL on the WP#/ACC pin, the de-
vice disables program and erase functions in the first
or last sector group independently of whether those
sector groups were protected or unprotected using the
method described in “Sector Group Protection and
Unprotection”. Note that if WP#/ACC is at VIL when the
device is in the standby mode, the maximum input
load current is increased. See the table in “DC Char-
acteristics”.
If the system asserts VIH on the WP#/ACC pin, the de-
vice reverts to whether the first or last sector was pre-
viously set to be protected or unprotected using the
method described in “Sector Group Protection and
Unprotection”.
Note that WP# has an internal pullup;
when unconnected, WP# is at V
IH
.
Temporary Sector Group Unprotect
This feature allows temporary unprotection of previ-
ously protected sector groups to change data in-sys-
tem. The Sector Group Unprotect mode is activated by
setting the RESET# pin to VID. During this mode, for-
merly 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 24 shows the timing
diagrams, for this feature.

SecSi (Secured Silicon) Sector Flash
Memory Region
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 secu-
rity of the ESN once the product is shipped to the field.
AMD offers the device with the SecSi Sector either
customer lockable (standard shipping option) or fac-
tory locked (contact an AMD sales representative for
ordering information). 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.
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.
Thus, the SecSi Sector Indicator Bit prevents cus-
tomer-lockable devices from being used to replace de-
vices that are factory locked.
Note that the ACC
function and unlock bypass modes are not available
when the SecSi Sector is enabled.
The SecSi sector address space in this device is allo-
cated as follows:
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 se-
quence, it may read the SecSi Sector by using the ad-
dresses normally occupied by the first sector (SA0).
This mode of operation continues until the system is-
sues 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.
Customer Lockable: SecSi Sector NOT
Programmed or Protected At the Factory
Unless otherwise specified, the device is shipped 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 meth-
ods, in addition to the standard programming com-
mand sequence. See Command Definitions.
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.
The SecSi Sector area can be protected using one of
the following procedures:
Write the three-cycle Enter SecSi Sector Region
command sequence, and then follow the in-system
sector protect algorithm as shown in Figure 2, ex-
cept that
RESET# may be at either V
IH
or V
ID
. 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.
Factory Locked: SecSi Sector Programmed and
Protected At the Factory
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. An ESN Factory
Locked device has an 16-byte random ESN at ad-
dresses 000000h–000007h. Please contact your local
AMD sales representative for details on ordering ESN
Factory Locked devices.
Customers may opt to have their code programmed by
AMD through the AMD ExpressFlash service (Express
Flash Factory Locked). 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.

Hardware Data Protection
The command sequence requirement of unlock cycles
for programming or erasing provides data protection
against inadvertent writes (refer to Tables 10 and 11
for command definitions). In addition, the following
hardware data protection measures prevent accidental
erasure or programming, which might otherwise be
caused by spurious system level signals during VCC
power-up and power-down transitions, or from system
noise.
Low VCC Write Inhibit
When VCC is less than VLKO, the device does not ac-
cept any write cycles. This protects data during VCC
power-up and power-down. The command register
and all internal program/erase circuits are disabled,
and the device resets to the read mode. Subsequent
writes are ignored until VCC is greater than VLKO. The
system must provide the proper signals to the control
pins to prevent unintentional writes when VCC is
greater than VLKO.
Write Pulse “Glitch” Protection
Noise pulses of less than 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# =
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 does not accept commands on the rising
edge of WE#. The internal state machine is automati-
cally reset to the read mode on power-up.
COMMON FLASH MEMORY INTERFACE (CFI)
The Common Flash Interface (CFI) specification out-
lines 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-inde-
pendent, 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 sys-
tem 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.
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 Specifi-
cation and CFI Publication 100, available via the World
Wide Web at http://www.amd.com/flash/cfi. Alterna-
tively, contact an AMD representative for copies of

DATASHEET
COMMAND DEFINITIONS
Writing specific address and data commands or se-
quences into the command register initiates device op-
erations. Tables 10 and 11 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 read-
ing 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
non-erase-suspended sector. After completing a pro-
gramming operation in the Erase Suspend mode, the
system may once again read array data with the same
exception. See the Erase Suspend/Erase Resume
Commands section for more information.
The system
must
issue the reset command to return
the device to the read (or erase-suspend-read) mode if
DQ5 goes high during an active program or erase op-
eration, or if the device is in the autoselect mode. See
the next section, Reset Command, for more informa-
tion.
See also Requirements for Reading Array Data in the
Device Bus Operations section for more information.
The Read-Only Operations table provides the read pa-
rameters, and Figure 14 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 se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to the read
mode. Once erasure begins, however, the device ig-
nores 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 be-
gins, however, the device ignores reset commands
until the operation 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 the read mode. If the de-
vice 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 Pro-
gramming 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.
Tables 10 and 11 show the address and data require-
ments. This method is an alternative to that shown in
Table 3, which is intended for PROM programmers
and requires VID 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 de-
vice 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 manu-
facturer code.
Three read cycles at addresses 01h, 0Eh, and 0Fh
return the device code.
A read cycle to an address containing a sector ad-
dress (SA), and the address 02h on A7–A0 in word
mode returns 01h if the sector is protected, or 00h if
it is unprotected.
The system must write the reset command to return to
the read mode (or erase-suspend-read mode if the de-
vice was previously in Erase Suspend).

DATASHEET
Enter SecSi Sector/Exit SecSi Sector
Command Sequence
The SecSi Sector region provides a secured data area
containing an 8-word/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 is-
sues the four-cycle Exit SecSi Sector command se-
quence. The Exit SecSi Sector command sequence
returns the device to normal operation. Tables 10 and
11 show the address and data requirements for both
command sequences. See also “SecSi (Secured Sili-
con) Sector Flash Memory Region” for further informa-
tion.
Note that the ACC function and unlock bypass
modes are not available when the SecSi Sector is en-
abled.
Word/Byte Program Command Sequence
Programming is a four-bus-cycle operation. The pro-
gram 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 al-
gorithm. 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. Tables 10 and 11 show the
address and data requirements for the word program
command sequence.
When the Embedded Program algorithm is complete,
the device then returns to the read mode and ad-
dresses are no longer latched. The system can deter-
mine the status of the program operation by using
DQ7 or DQ6. Refer to the Write Operation Status sec-
tion for information on these status bits.
Any commands written to the device during the Em-
bedded 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 suc-
cessful. 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 pro-
gram words to the device faster than using the stan-
dard program command sequence. The unlock bypass
command sequence is initiated by first writing two un-
lock cycles. This is followed by a third write cycle con-
taining the unlock bypass command, 20h. The device
then enters the unlock bypass mode. A two-cycle un-
lock 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 com-
mand, 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 program-
ming time. Tables 10 and 11 show the requirements
for the command sequence.
During the unlock bypass mode, only the Unlock By-
pass Program and Unlock Bypass Reset commands
are valid. To exit the unlock bypass mode, the system
must issue the two-cycle unlock bypass reset com-
mand 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 write to a
maximum of 16 words/32 bytes in one programming
operation. This results in faster effective programming
time than the standard programming algorithms. The
Write Buffer Programming command sequence is initi-
ated 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 pro-
gramming will occur. The fourth cycle writes the sector
address and the number of word locations, minus one,
to be programmed. For example, if the system will pro-
gram 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. The write-buffer-page is se-
lected by address bits AMAX–A4. All subsequent ad-
dress/data pairs must fall within the
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.
(This means Write Buffer Programming cannot be per-
formed across multiple write-buffer pages. This also
September 9, 2003 Am29LV128MH/L 29
DATASHEET
means that Write Buffer Programming cannot be per-
formed across multiple 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
system must therefore account for loading a
write-buffer location more than once. The counter dec-
rements for each data load operation, not for each
unique write-buffer-address location. 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 Pro-
gram 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 sus-
pended 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 com-
mand.
Write an Address/Data pair to a different
write-buffer-page than the one selected by the
Starting Address during the write buffer data load-
ing 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 de-
vice for the next operation. Note that the full 3-cycle
Write-to-Buffer-Abort Reset command sequence is re-
quired when using Write-Buffer-Programming features
in Unlock Bypass mode.
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 suc-
cessful. However, a succeeding read will show that the
data is still “0.” Only erase operations can convert a “0”
to a “1.
Accelerated Program
The device offers accelerated program operations
through the WP#/ACC pin. When the system asserts
VHH on the WP#/ACC pin, the device automatically en-
ters the Unlock Bypass mode. The system may then
write the two-cycle Unlock Bypass program command
sequence. The device uses the higher voltage on the
WP#/ACC pin to accelerate the operation.
Note that
the
WP#/
ACC pin must not be at V
HH
for operations
other than accelerated programming, or device dam-
age may result. WP# has an internal pullup; when un-
connected, WP# is at V
IH
.
Figure 5 illustrates the algorithm for the program oper-
ation. Refer to the Erase and Program Operations
table in the AC Characteristics section for parameters,

Figure 5. Program Operation
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 Sus-
pend command is written during a programming pro-
cess, 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 sus-
pended, the system can read array data from any
non-suspended sector. The Program Suspend com-
mand may also be issued during a programming oper-
ation while an erase is suspended. In this case, data
may be read from any addresses not in Erase Sus-
pend 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 for more information.
After the Program Resume command is written, the
device reverts to programming. The system can deter-
mine the status of the program operation using the
DQ7 or DQ6 status bits, just as in the standard pro-
gram operation. See Write Operation Status for more
information.
The system must write the Program Resume com-
mand to exit the Program Suspend mode and continue
the programming operation. The address of the pro-
gram-suspended sector is required when writing this
command. 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 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. Tables 10 and
11 show the address and data requirements for the
chip erase command sequence.
When the Embedded Erase algorithm is complete, the
device returns to the read mode and addresses are no
longer latched. The system can determine the status
of the erase operation by using DQ7, DQ6, or DQ2.
Refer to the Write Operation Status section for infor-
mation on these status bits.
Any commands written during the chip erase operation
are ignored.However, note that a hardware reset im-
mediately terminates the erase operation. If that oc-
curs, the chip erase command sequence should be
reinitiated once the device has returned to reading
array data, to ensure data integrity.
Note that the
SecSi Sector, autoselect, and CFI functions are un-
available when an program operation is in progress.
Figure 6 illustrates the algorithm for the erase opera-
tion. Refer to the Erase and Program Operations ta-
bles in the AC Characteristics section for parameters,
and Figure 20 section for timing diagrams.
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 cycles are written, and are then fol-
lowed by the address of the sector to be erased, and
the sector erase command. Tables 9 & 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 auto-
matically 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 tim-
ings 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 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
between these additional cycles must be less than 50
µs, otherwise erasure may begin. Any sector erase ad-
dress 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 en-
sure 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 re-
write the command sequence and any additional ad-
dresses and commands.
Note that the SecSi Sector,
autoselect, and CFI functions are unavailable when an
erase operation is in progress.

The system can monitor DQ3 to determine if the sec-
tor erase timer has timed out (See the section on DQ3:
Sector Erase Timer.). The time-out begins from the ris-
ing 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, or
DQ2 in the erasing sector. Refer to the Write Opera-
tion Status section for information on these status bits.
Once the sector erase operation has begun, only the
Erase Suspend command is valid. All other com-
mands 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 opera-
tion. Refer to the Erase and Program Operations ta-
bles in the AC Characteristics section for parameters,
and Figure 20 section for timing diagrams.
Erase Suspend/Erase Resume
Commands
The Erase Suspend command, B0h, allows the sys-
tem 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 sec-
tor erase operation, including the 50 µs time-out pe-
riod 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 typi-
cal of 5 µs (maximum of 20 µs) to suspend the erase
operation. However, when the Erase Suspend com-
mand 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
device enters the erase-suspend-read mode. The sys-
tem can read data from or program data to any sector
not selected for erasure. (The device “erase sus-
pends” all sectors selected for erasure.) Reading at
any address within erase-suspended sectors pro-
duces 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.
Refer to the Write Operation Status section for infor-
mation on these status bits.
After an erase-suspended program operation is com-
plete, 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 word program operation.
Refer to the Write Operation Status section for more
information.
In the erase-suspend-read mode, the system can also
issue the autoselect command sequence. Refer to the
Autoselect Mode and Autoselect Command Sequence
sections for details.
To resume the sector erase operation, the system
must write the Erase Resume command. The address
of the erase-suspended sector is required when writ-
ing this command. Further writes of the Resume com-
mand are ignored. Another Erase Suspend command
can be written after the chip has resumed erasing.

DATASHEET
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 12 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 com-
plete or in progress. The device also provides a hard-
ware-based output signal, RY/BY#, to determine
whether an Embedded Program or Erase operation is
in progress or has been completed.
DQ7: Data# Polling
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 out-
puts 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 ac-
tive for approximately 1 µs, then the device returns to the
read mode.
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 infor-
mation on DQ7.
After an erase command sequence is written, if all
sectors selected for erasing are protected, Data# Poll-
ing 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 se-
lected sectors that are protected. However, if the sys-
tem 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
the status or valid data. Even if the device has com-
pleted the program or erase operation and DQ7 has
valid data, the data outputs on DQ0–DQ6 may be still
invalid. Valid data on DQ0–DQ7 will appear on suc-
cessive read cycles.
Table 12 shows the outputs for Data# Polling on DQ7.
Figure 8 shows the Data# Polling algorithm. Figure 21
in the AC Characteristics section shows the Data#
Polling timing diagram.

Notes:

erase operation, a valid address is any sector address
within the sector being erased. 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.

DATASHEET
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, sev-
eral RY/BY# pins can be tied together in parallel with a
pull-up resistor to VCC.
If the output is low (Busy), the device is actively eras-
ing 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 in the erase-suspend-read mode. Table 12
shows the outputs for RY/BY#.
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded
Program or Erase algorithm is in progress or com-
plete, or whether the device has entered the Erase
Suspend mode. Toggle Bit I may be read at any ad-
dress, 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 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 toggles for approxi-
mately 100 µs, then returns to reading array data. If not all
selected sectors are protected, the Embedded Erase algo-
rithm erases the unprotected sectors, and ignores the se-
lected 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 de-
vice enters the Erase Suspend mode, DQ6 stops toggling.
However, the system must also use DQ2 to determine
which sectors are erasing or erase-suspended. Alterna-
tively, the system can use DQ7 (see the subsection on
DQ7: Data# Polling).
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.
DQ6 also toggles during the erase-suspend-program
mode, and stops toggling once the Embedded Pro-
gram algorithm is complete.
Table 12 shows the outputs for Toggle Bit I on DQ6.
Figure 9 shows the toggle bit algorithm. Figure 22 in
the “AC Characteristics” section shows the toggle bit
timing diagrams. Figure 23 shows the differences be-
tween DQ2 and DQ6 in graphical form. See also the
subsection on DQ2: Toggle Bit II.

DATASHEET
Figure 9. Toggle Bit Algorithm
DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, indi-
cates 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 era-
sure. (The system may use either OE# or CE# to con-
trol the read cycles.) But DQ2 cannot distinguish
whether the sector is actively erasing or is erase-sus-
pended. DQ6, by comparison, indicates whether the
device is actively erasing, or is in Erase Suspend, but
cannot distinguish which sectors are selected for era-
sure. Thus, both status bits are required for sector and
mode information. Refer to Table 12 to compare out-
puts for DQ2 and DQ6.
Figure 9 shows the toggle bit algorithm in flowchart
form, and the section “DQ2: Toggle Bit II” explains the
algorithm. See also the RY/BY#: Ready/Busy# sub-
section. Figure 22 shows the toggle bit timing diagram.
Figure 23 shows the differences between DQ2 and
DQ6 in graphical form.
Reading Toggle Bits DQ6/DQ2
Refer to Figure 9 for the following discussion. When-
ever the system initially begins reading toggle bit sta-
tus, 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 tog-
gle 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 fol-
lowing read cycle.
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the sys-
tem 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 tog-
gling, 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 de-
vice 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 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 cy-
cles, determining the status as described in the previ-
ous paragraph. Alternatively, it may choose to perform

Note: The system should recheck the toggle bit even if
DQ5 = “1” because the toggle bit may stop toggling as DQ5
changes to “1.” See the subsections on DQ6 and DQ2 for
more information.

other system tasks. In this case, the system must start
at the beginning of the algorithm when it returns to de-
termine the status of the operation (top of Figure 9).
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 suc-
cessfully completed.
The device may output a “1” on DQ5 if the system tries
to program a “1” to a location that was previously pro-
grammed 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 com-
mand. When the time-out period is complete, DQ3
switches from a “0” to a “1.” If the time between addi-
tional sector erase commands from the system can be
assumed to be less than 50 µs, the system need not
monitor DQ3. See also the Sector Erase Command
Sequence section.
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 fur-
ther 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 sys-
tem software should check the status of DQ3 prior to
and following each subsequent sector erase com-
mand. If DQ3 is high on the second status check, the
last command might not have been accepted.
Table 12 shows the status of DQ3 relative to the other
status bits.
DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation
was aborted. Under these conditions DQ1 produces a
“1”. The system must issue the
Write-to-Buffer-Abort-Reset command sequence to re-
turn the device to reading array data. See Write Buffer
Programming section for more details.

Notes:
1. DQ5 switches to ‘1’ when an Embedded Program, Embedded Erase, or Write-to-Buffer operation has exceeded the
maximum timing limits. Refer to the section on DQ5 for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.
4. DQ1 switches to ‘1’ when the device has aborted the write-to-buffer operation.

ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25
°
C, 3.0 V V
CC
. Programming specifications assume that
all bits are programmed to 00h.
2. Maximum values are measured at VCC = 3.0, worst case temperature. Maximum values are valid up to and including 100,000
program/erase cycles.
3. Byte/Word programming specification is based upon a single word/byte programming operation not utilizing the write buffer.
4. For 1-16 words or 1-32 bytes programmed in a single write buffer programming operation.
5. Effective write buffer specification is based upon a 16-word/32-byte write buffer operation.
6. The typical chip programming time is considerably less than the maximum chip programming time listed, since most words
program faster than the maximum program times listed.
7. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
8. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table
11 for further information on command definitions.
9. The device has a minimum erase and program cycle endurance of 100,000 cycles.
