GENERAL DESCRIPTION (PDL129)
The Am29PDL129H is a 128 Mbit, 3.0 volt-only Page Mode
and Simultaneous Read/Write Flash memory device organized as 8 Mwords. The word-wide data (x16) appears on
DQ15-DQ0. This device can be programmed in-system or in
standard EPROM programmers. A 12.0 V VPP is not required
for write or erase operations.
The device offers fast page access time of 25 and 30 ns,
with corresponding random access times of 65 and 85 ns,
respectively, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#f1, CE#f2), write enable
(WE#) and output enable (OE#) controls. Dual Chip Enables
allow access to two 64 Mbit partitions of the 128 Mbit memory space.
Simultaneous Read/Write Operation with
Zero Latency
The Simultaneous Read/Write architecture provides simultaneous operation by dividing the memory space into 4
banks, which can be considered to be four separate memory
arrays as far as certain operations are concerned. The device can improve overall system performance by allowing a
host system to program or erase in one bank, then immediately and simultaneously read from another bank with zero
latency (with two simultaneous operations operating at any
one time). This releases the system from waiting for the
completion of a program or erase operation, greatly improving system performance.
The device can be organized in both top and bottom sector
configurations. The banks are organized as follows:
Chip Enable Configuration
CE#f1 Control
CE#f2 Control
Bank 1A
48 Mbit (32 Kw x 96)
Bank 2A
16 Mbit (4 Kw x 8 and 32 Kw x 31)
Bank 1B
16 Mbit (4 Kw x 8 and 32 Kw x 31)
Bank 2B
48 Mbit (32 Kw x 96)
Page Mode Features
The page size is 8 words. After initial page access is accomplished, the page mode operation provides fast read access
speed of random locations within that page.
Standard Flash Memory Features
The device requires a single 3.0 volt power supply (2.7 V
to 3.1 V) for both read and write functions. Internally generated and regulated voltages are provided for the program
and erase operations.
4
The device is entirely command set compatible with the
JEDEC 42.4 single-power-supply Flash standard. Commands are written to the command register using standard
microprocessor write timing. Register contents serve as inputs to an internal state-machine that controls the erase and
programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase
operations. Reading data out of the device is similar to reading from other Flash or EPROM devices.
Device programming occurs by executing the program command sequence. The Unlock Bypass mode facilitates faster
programming times by requiring only two write cycles to program data instead of four. Device erasure occurs by executing the erase command sequence.
The host system can detect whether a program or erase operation is complete by reading the DQ7 (Data# Polling) and
DQ6 (toggle) status bits. After a program or erase cycle has
been completed, the device is ready to read array data or accept another command.
The sector erase architecture allows memory sectors to be
erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when
shipped from the factory.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations during
power transitions. The hardware sector protection feature
disables both program and erase operations in any combination of sectors of memory. This can be achieved in-system or
via programming equipment.
The Erase Suspend/Erase Resume feature enables the
user to put erase on hold for any period of time to read data
from, or program data to, any sector that is not selected for
erasure. True background erase can thus be achieved. If a
read is needed from the SecSi Sector area (One Time Program area) after an erase suspend, then the user must use
the proper command sequence to enter and exit this region.
The device offers two power-saving features. When addresses have been stable for a specified amount of time, the
device enters the automatic sleep mode. The system can
also place the device into the standby mode. Power consumption is greatly reduced in both these modes.
AMD’s Flash technology combined 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
Fowler-Nordheim tunneling. The data is programmed using
hot electron injection.

MCP 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
14
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. Tables 1-2 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.

Notes:
1. Other operations except for those indicated in this column are

2. Do not apply CE#f1 or 2 = VIL, CE#1ps = VIL and CE2ps = VIH at
the same time.
3. Don’t care or open LB#s or UB#s.
4. If WP#/ACC = VIL, the boot sectors will be protected. If WP#/ACC
= VIH the boot sectors protection will be removed.
If WP#/ACC = VACC (9V), the program time will be reduced by
40%.
6. If WP#/ACC = VIL, the two outermost boot sectors remain
protected. If WP#/ACC = VIH, the two outermost boot sector
protection depends on whether they were last protected or
unprotected using the method described in “Sector/Sector Block
Protection and Unprotection”. If WP#/ACC = VHH, all sectors will
be unprotected.
7. Data will be retained in pSRAM.
8. Data will be lost in pSRAM.
9.
Both CE#f1 inputs may be held low for this operation.
5. The sector protect and sector unprotect functions may also be
implemented via programming equipment. See the “Sector/Sector
Block Protection and Unprotection” section.

Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the OE# and appropriate CE#f1/CE#f2 (PDL129
only) pins to VIL. CE#f1 and CE#f2 are the power control. OE# is the output control and gates array data to
the output pins. WE# should remain at VIH.
A22–A3 (A21–A3 for PDL129) constant and changing
A2 to A0 to select the specific word within that page.
Table 2.
The internal state machine is set for reading array data
upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory
content occurs during the power transition. No command is necessary in this mode to obtain array data.
Standard microprocessor read cycles that assert valid
addresses on the device address inputs produce valid
data on the device data outputs. Each bank remains
enabled for read access until the command register
contents are altered.
Refer to the Flash AC Characteristics table for timing
specifications and to Figure 12 for the timing diagram.
ICC1 in the DC Characteristics table represents the active current specification for reading array data.
Random Read (Non-Page Read)
Address access time (tACC) is equal to the delay from
stable addresses to valid output data. The chip enable
access time (t CE ) is the delay from the stable addresses and stable CE#f1 to valid data at the output
inputs. The output enable access time is the delay
from the falling edge of the OE# to valid data at the
output inputs (assuming the addresses have been stable for at least tACC–tOE time).
The random or initial page access is tACC or tCE and
subsequent page read accesses (as long as the locations specified by the microprocessor fall within that
page) are t PACC. When CE#f1 and CE#f2 (PDL129
only) are deasserted (CE#f1=CE#f2=VIH), the reassertion of CE#f1 or CE#f2 (PDL129 only) for subsequent
access has access time of t ACC or t CE . Here again,
CE#f1/CE#f2 (PDL129 only) selects the device and
OE# is the output control and should be used to gate
data to the output inputs if the device is selected. Fast
page mode accesses are obtained by keeping

Simultaneous Operation
In addition to the conventional features (read, program, erase-suspend read, and erase-suspend program), the device is capable of reading data from one
bank of memory while a program or erase operation is
in progress in another bank of memory (simultaneous
operation), The bank can be selected by bank addresses (A22–A20) (A21–A20 for PDL129) with zero
latency.
The simultaneous operation can execute multi-function mode in the same bank.
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. Address bits
A22–A3 (A21–A3 for PDL129) select an 8-word page,
and address bits A2–A0 select a specific word within
that page. This is an asynchronous operation with the
microprocessor supplying the specific word location.

Writing Commands/Command Sequences
Autoselect Functions
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#f1 or CE#f2 (PDL 129 only) to VIL, and OE# to VIH.
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 DQ15–DQ0. Standard read cycle timings apply in
this mode. Refer to the Autoselect Command Sequence sections for more information.
The device features an Unlock Bypass mode to facilitate faster programming. Once a bank enters the Unlock Bypass mode, only two write cycles are required
to program a word, instead of four. The “Word Program Command Sequence” section 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 4 indicates the address
space that each sector occupies. A “bank address” is
the address bits required to uniquely select a bank.
Similarly, a “sector address” refers to the address bits
required to uniquely select a sector. The “Command
Definitions” section has details on erasing a sector or
the entire chip, or suspending/resuming the erase operation.
ICC2 in the DC Characteristics table represents the active current specification for the write mode. The Flash
AC Characteristics section contains timing specification tables and timing diagrams for write operations.
Accelerated Program Operation
The device offers accelerated program operations
through the ACC function. This function is primarily intended to allow faster manufacturing throughput at the
factory.
If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass
mode, temporarily unprotects any protected sectors,
and uses the higher voltage on the pin to reduce the
time required for program operations. The system
would use a two-cycle program command sequence
as required by the Unlock Bypass mode. Removing
VHH from the WP#/ACC pin returns the device to normal operation. Note that VHH must not be asserted on
WP#/ACC for operations other than accelerated programming, or device damage may result. In addition,
the WP#/ACC pin should be raised to VCC when not in
use. That is, the WP#/ACC pin should not be left floating or unconnected; inconsistent behavior of the device may result.

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#f1, CE#f2 (PDL129 only) and RESET# pins are all
held at VIO ± 0.3 V. (Note that this is a more restricted
voltage range than V IH .) If CE#f1, CE#f2 (PDL129
only), and RESET# are held at VIH, but not within VCC
± 0.3 V, the device will be in the standby mode, but the
standby current will be greater. The device requires
standard access time (tCE) for read access when the
device is in either of these standby modes, before it is
ready to read data.
If the device is deselected during erasure or programming, the device draws active current until the
operation is completed.
ICC3 in the DC Characteristics table represents the
CMOS 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 t ACC +
150 ns. The automatic sleep mode is independent of
the CE#f1/CE#f2 (PDL129 only), 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. Note that during automatic sleep
mode, OE# must be at VIH before the device reduces
current to the stated sleep mode specification. ICC5 in
the DC Characteristics table represents the automatic
sleep mode current specification.

RESET#: Hardware Reset Pin
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 (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 circuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory.
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a “0” (busy) until the
18
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 tREADY (not during Embedded Algorithms). The system can read data tRH after the RESET# pin returns to VIH.
Refer to the pSRAM AC Characteristics tables for RESET# parameters and to Figure 11 for the timing diagram.
Output Disable Mode
When the OE# input is at VIH, output from the device is
disabled. The output pins (except for RY/BY#) are
placed in the highest Impedance state

SECTOR PROTECTION
The Am29PDL127H/Am29PDL129H features several
levels of sector protection, which can disable both the
program and erase operations in certain sectors or
sector groups:
■ Dynamically Locked—The sector is protected and
can be changed by a simple command.
Persistent Sector Protection
To achieve these states, three types of “bits” are used:
A command sector protection method that replaces
the old 12 V controlled protection method.
Persistent Protection Bit (PPB)
Password Sector Protection
A highly sophisticated protection method that requires
a password before changes to certain sectors or sector groups are permitted.
WP# Hardware Protection
A write protect pin that can prevent program or erase
operations in sectors 0, 1, 268, and 269 in PDL 127 or
in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129. The
WP# Hardware Protection feature is always available,
regardless of which of the other two methods are chosen.
Selecting a Sector Protection Mode
The device defaults to the Persistent Sector Protection
mode. However, to prevents a program or virus from
later setting the Password Mode Locking Bit, which
would cause an unexpected shift from the default Persistent Sector Protection Mode into the Password Protection Mode, it is recommended that either of two
one-time programmable non-volatile bits that permanently define which sector protection method be set
before the device is first programmed. The Persistent Sector Protection Mode Locking Bit permanently sets the device to the Persistent Sector
Protection mode. The Password Mode Locking Bit
permanently sets the device to the Password Sector
Protection mode. It is not possible to switch between
the two protection modes once a locking bit has been
set.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sectors at the 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 is protected or unprotected. See Autoselect Command Sequence for details.
Persistent Sector Protection
The Persistent Sector Protection method replaces the
12 V controlled protection method in previous AMD
flash devices. This new method provides three different sector protection states:
■ Persistently Locked—The sector is protected and
cannot be changed.
36
■ Unlocked—The sector is unprotected and can be
changed by a simple command.
A single Persistent (non-volatile) Protection Bit is assigned to a maximum four sectors (see the sector address tables for specific sector protection groupings).
All 4 Kword boot-block sectors have individual sector
Persistent Protection Bits (PPBs) for greater flexibility.
Each PPB is individually modifiable through the PPB
Write Command.
The device erases all PPBs in parallel. If any PPB requires erasure, the device must be instructed to preprogram all of the sector PPBs prior to PPB erasure.
Otherwise, a previously erased sector PPBs can potentially be over-erased. The flash device does not
have a built-in means of preventing sector PPBs
over-erasure.
Persistent Protection Bit Lock (PPB Lock)
The Persistent Protection Bit Lock (PPB Lock) is a global volatile bit. When set to “1”, the PPBs cannot be
changed. When cleared (“0”), the PPBs are changeable. There is only one PPB Lock bit per device. The
PPB Lock is cleared after power-up or hardware reset.
There is no command sequence to unlock the PPB
Lock.
Dynamic Protection Bit (DYB)
A volatile protection bit is assigned for each sector.
After power-up or hardware reset, the contents of all
DYBs is “0”. Each DYB is individually modifiable
through the DYB Write Command.
When the par ts are first shipped, the PPBs are
cleared, the DYBs are cleared, and PPB Lock is defaulted to power up in the cleared state – meaning the
PPBs are changeable.
When the device is first powered on the DYBs power
up cleared (sectors not protected). The Protection
State for each sector is determined by the logical OR
of the PPB and the DYB related to that sector. For the
sectors that have the PPBs cleared, the DYBs control
whether or not the sector is protected or unprotected.
By issuing the DYB Write command sequences, the
DYBs will be set or cleared, thus placing each sector in
the protected or unprotected state. These are the
so-called Dynamic Locked or Unlocked states. They
are called dynamic states because it is very easy to
switch back and forth between the protected and unprotected conditions. This allows software to easily
protect sectors against inadvertent changes yet does

not prevent the easy removal of protection when
changes are needed. The DYBs maybe set or cleared
as often as needed.
The PPBs allow for a more static, and difficult to
change, level of protection. The PPBs retain their state
across power cycles because they are non-volatile. Individual PPBs are set with a command but must all be
cleared as a group through a complex sequence of
program and erasing commands. The PPBs are also
limited to 100 erase cycles.
The PPB Lock bit adds an additional level of protection. Once all PPBs are programmed to the desired
settings, the PPB Lock may be set to “1”. Setting the
PPB Lock disables all program and erase commands
to the non-volatile PPBs. In effect, the PPB Lock Bit
locks the PPBs into their current state. The only way to
clear the PPB Lock is to go through a power cycle.
System boot code can determine if any changes to the
PPB are needed; for example, to allow new system
code to be downloaded. If no changes are needed
then the boot code can set the PPB Lock to disable
any further changes to the PPBs during system operation.
The WP#/ACC write protect pin adds a final level of
hardware protection to sectors 0, 1, 268, and 269 in
PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in
PDL 129. When this pin is low it is not possible to
change the contents of these sectors. These sectors
generally hold system boot code. The WP#/ACC pin
can prevent any changes to the boot code that could
override the choices made while setting up sector protection during system initialization.
It is possible to have sectors that have been persistently locked, and sectors that are left in the dynamic
state. The sectors in the dynamic state are all unprotected. If there is a need to protect some of them, a
simple DYB Write command sequence is all that is
necessary. The DYB write command for the dynamic
sectors switch the DYBs to signify protected and unprotected, respectively. If there is a need to change the
status of the persistently locked sectors, a few more
steps are required. First, the PPB Lock bit must be disabled by either putting the device through a power-cycle, or hardware reset. The PPBs can then be
changed to reflect the desired settings. Setting the
PPB lock bit once again will lock the PPBs, and the device operates normally again.
The best protection is achieved by executing the PPB
lock bit set command early in the boot code, and protect the boot code by holding WP#/ACC = VIL.

Table 11 contains all possible combinations of the
DYB, PPB, and PPB lock relating to the status of the

In summary, if the PPB is set, and the PPB lock is set,
the sector is protected and the protection can not be
removed until the next power cycle clears the PPB
lock. If the PPB is cleared, the sector can be dynamically locked or unlocked. The DYB then controls
whether or not the sector is protected or unprotected.
If the user attempts to program or erase a protected
sector, the device ignores the command and returns to
read mode. A program command to a protected sector
enables status polling for approximately 1 µs before
the device returns to read mode without having modified the contents of the protected sector. An erase
command to a protected sector enables status polling
for approximately 50 µs after which the device returns
to read mode without having erased the protected sector.

Persistent Sector Protection Mode Locking Bit
Like the password mode locking bit, a Persistent Sector Protection mode locking bit exists to guarantee that
the device remain in software sector protection. Once
set, the Persistent Sector Protection locking bit prevents programming of the password protection mode
locking bit. This guarantees that a hacker could not
place the device in password protection mode.
Password Protection Mode
The Password Sector Protection Mode method allows
an even higher level of security than the Persistent
Sector Protection Mode. There are two main differ-

37

I N F O R M A T I O N
ences between the Persistent Sector Protection and
the Password Sector Protection Mode:
■ When the device is first powered on, or comes out
of a reset cycle, the PPB Lock bit set to the locked
state, rather than cleared to the unlocked state.
■ The only means to clear the PPB Lock bit is by writing a unique 64-bit Password to the device.
The Password Sector Protection method is otherwise
identical to the Persistent Sector Protection method.
A 64-bit password is the only additional tool utilized in
this method.
Once the Password Mode Locking Bit is set, the password is permanently set with no means to read, program, or erase it. The password is used to clear the
PPB Lock bit. The Password Unlock command must
be written to the flash, along with a password. The
flash device internally compares the given password
with the pre-programmed password. If they match, the
PPB Lock bit is cleared, and the PPBs can be altered.
If they do not match, the flash device does nothing.
There is a built-in 2 µs delay for each “password
check.” This delay is intended to thwart any efforts to
run a program that tries all possible combinations in
order to crack the password.
Password and Password Mode Locking Bit
In order to select the Password sector protection
scheme, the customer must first program the password. The password may be correlated to the unique
Electronic Serial Number (ESN) of the particular flash
device. Each ESN is different for every flash device;
therefore each password should be different for every
flash device. While programming in the password region, the customer may perform Password Verify operations.
Once the desired password is programmed in, the
customer must then set the Password Mode Locking
Bit. This operation achieves two objectives:
1. Permanently sets the device to operate using the
Password Protection Mode. It is not possible to reverse this function.
2. Disables all further commands to the password region. All program, and read operations are ignored.
Both of these objectives are important, and if not carefully considered, may lead to unrecoverable errors.
The user must be sure that the Password Protection
method is desired when setting the Password Mode
Locking Bit. More importantly, the user must be sure
that the password is correct when the Password Mode
Locking Bit is set. Due to the fact that read operations
are disabled, there is no means to verify what the
password is afterwards. If the password is lost after
setting the Password Mode Locking Bit, there will be
no way to clear the PPB Lock bit.
38
The Password Mode Locking Bit, once set, prevents
reading the 64-bit password on the DQ bus and further
password programming. The Password Mode Locking
Bit is not erasable. Once Password Mode Locking Bit
is programmed, the Persistent Sector Protection Locking Bit is disabled from programming, guaranteeing
that no changes to the protection scheme are allowed.
64-bit Password
The 64-bit Password is located in its own memory
space and is accessible through the use of the Password Program and Verify commands (see “Password
Verify Command”). The password function works in
conjunction with the Password Mode Locking Bit,
which when set, prevents the Password Verify command from reading the contents of the password on
the pins of the device.
Write Protect (WP#)
The Write Protect feature provides a hardware method
of protecting sectors 0, 1, 268, and 269 in PDL 127 or
in SA1-133, SA1-134, SA2-0, SA2-1 in PDL 129 without using VID. This function is provided by the WP# pin
and overrides the previously discussed High Voltage
Sector Protection method.
If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the two
outermost 4 Kword sectors on both ends of the flash
array independent of whether it was previously protected or unprotected.
If the system asserts VIH on the WP#/ACC pin, the device reverts to whether sectors 0, 1, 268, and 269 in
PDL 127 or in SA1-133, SA1-134, SA2-0, SA2-1 in
PDL 129 were last set to be protected or unprotected.
That is, sector protection or unprotection for these sectors depends on whether they were last protected or
unprotected using the method described in High Voltage Sector Protection.
Note that the WP#/ACC pin must not be left floating or
unconnected; inconsistent behavior of the device may
result.
Persistent Protection Bit Lock
The Persistent Protection Bit (PPB) Lock is a volatile
bit that reflects the state of the Password Mode Locking Bit after power-up reset. If the Password Mode
Lock Bit is also set after a hardware reset (RESET#
asserted) or a power-up reset, the ONLY means for
clearing the PPB Lock Bit in Password Protection
Mode is to issue the Password Unlock command. Successful execution of the Password Unlock command
clears the PPB Lock Bit, allowing for sector PPBs
modifications. Asserting RESET#, taking the device
through a power-on reset, or issuing the PPB Lock Bit
Set command sets the PPB Lock Bit to a “1” when the
Password Mode Lock Bit is not set.

If the Password Mode Locking Bit is not set, including
Persistent Protection Mode, the PPB Lock Bit is
cleared after power-up or hardware reset. The PPB

Lock Bit is by issuing a hardware or power-up reset.
The Password Unlock command is ignored in Persistent Protection Mode.

High Voltage Sector Protection
Sector protection and unprotection may also be implemented using programming equipment. The procedure requires high voltage (VID ) to be placed on the
RESET# pin. Refer to Figure 1 for details on this procedure. Note that for sector unprotect, all unprotected
sectors must first be protected prior to the first sector
write cycle.

Temporary Sector Unprotect
This feature allows temporary unprotection of previously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly protected
sectors can be programmed or erased by selecting the
sector addresses. Once VID is removed from the RESET# pin, all the previously protected sectors are
protected again. Figure 2 shows the algorithm, and

has written the Enter SecSi Sector command sequence, it may read the SecSi Sector by using the addresses normally occupied by the boot sectors. This
mode of operation continues until the system issues

Hardware Data Protection
The command sequence requirement of unlock cycles
for programming or erasing provides data protection
against inadvertent writes. 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 accept any write cycles. This protects data during VCC
power-up and power-down. The command register
and all internal program/erase circuits are disabled,
and the device resets to 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 V CC is
greater than VLKO.
Write Pulse “Glitch” Protection
Noise pulses of less than 3 ns (typical) on OE#,
CE#f1, CE#f2 or WE# do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by holding any one of OE# =
V IL, CE#f1 =CE#f2 = VIH or WE# = VIH . To initiate a
write cycle, CE#f1/CE#f2 and WE# must be a logical
zero while OE# is a logical one.
Power-Up Write Inhibit
If WE# = CE#f1 = VIL and OE# = VIH during power up,
the device does not accept commands on the rising
November 24, 2003
edge of WE#. The internal state machine is automatically reset to the read mode on power-up.
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 12–15. To terminate reading CFI data,
the system must write the reset command. The CFI
Query mode is not accessible when the device is executing an Embedded Program or embedded Erase algorithm.
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 12–15. 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 16 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#f1/CE#f2 (PDL129H only), whichever happens
later. All data is latched on the rising edge of WE# or
CE#f1/CE#f2 (PDL129H only), whichever happens
first. Refer to the Flash 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. Each bank is ready to read array data
after completing an Embedded Program or Embedded
Erase algorithm.
After the device accepts an Erase Suspend command,
the corresponding ban k enters the erase-suspend-read mode, after which the system can read
data from any non-erase-suspended sector within the
same bank. The system can read array data using the
standard read timing, except that if it reads at an address within erase-suspended sectors, the device outputs status data. After completing a programming
operation in the Erase Suspend mode, the system
may once again read array data with the same exception. See the Erase Suspend/Erase Resume Commands section for more information.
The system must issue the reset command to return a
bank to the read (or erase-suspend-read) mode if DQ5
goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the
next section, Reset Command, for more information.
See also Requirements for Reading Array Data in the
MCP Device Bus Operations section for more information. The Read-Only Operations – Am29PDL127H and
Read-Only Operations – Am29PDL127H tables provide the read parameters, and Figure 12 shows the
timing diagram.
Reset Command
Writing the reset command resets the banks to the
read or erase-suspend-read mode. Address bits are
don’t cares for this command.
The reset command may be written between the sequence cycles in an erase command sequence before
November 24, 2003
erasing begins. This resets the bank to which the system was writing 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 bank to
which the system was writing to the read mode. If the
program command sequence is written to a bank that
is in the Erase Suspend mode, writing the reset
co m m an d re tur ns th a t ba nk to the e ra se- 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 a bank
entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that
bank to the erase-suspend-read mode.
If DQ5 goes high during a program or erase operation,
writing the reset command returns the banks to the
read mode (or erase-suspend-read mode if that bank
was in Erase Suspend).
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.
The autoselect command sequence may be written to
an address within a bank 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 in the other bank.
The autoselect command sequence is initiated by first
writing two unlock cycles. This is followed by a third
write cycle that contains the bank address and the autoselect command. The bank then enters the autoselect mode. The system may read any number of
autoselect codes without reinitiating the command sequence.
Table 16 shows the address and data requirements.
To determine sector protection information, the system
must write to the appropriate bank address (BA) and
sector address (SA). Table 4 shows the address range
and bank number associated with each sector.
The system must write the reset command to return to
the read mode (or erase-suspend-read mode if the
bank was previously in Erase Suspend).

Enter SecSi™ Sector/Exit SecSi Sector
Command Sequence
The SecSi Sector region provides a secured data area
containing a random, eight word 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. The SecSi Sector is not accessible when the device is executing an Embedded
Program or embedded Erase algorithm. Table 16
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.
Word 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 16 shows the address
and data requirements for the program command sequence.
When the Embedded Program algorithm is complete,
that bank 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#. Refer to the Write Operation
Status section for information on these status bits.
Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a
hardware reset immediately terminates the program
operation. Note that the SecSi sector, autoselect, and
CFI functions are unavailable when the SecSi Sector
is enabled. The program command sequence should
be reinitiated once that bank has returned to the read
mode, to ensure data integrity.
48
Programming is allowed in any sequence and across
sector boundaries. A bit cannot be programmed
from “0” back to a “1.” Attempting to do so may
cause that bank to set 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 data to a bank faster than using the standard
program command sequence. The unlock bypass
command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. That bank
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 16 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 device offers accelerated program operations
through the WP#/ACC pin. When the system asserts
VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then
write the two-cycle Unlock Bypass program command
sequence. The device uses the higher voltage on the
WP#/ACC pin to accelerate the operation. Note that
the WP#/ACC pin must not be at V HH any operation
other than accelerated programming, or device damage may result. In addition, the WP#/ACC pin must not
be left floating or unconnected; inconsistent behavior
of the device may result.
Figure 3 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations
table in the AC Characteristics section for parameters,
and Figures 12 and 13 for timing diagrams.

Program Operation
Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase
command sequence is initiated by writing two unlock
cycles, followed by a set-up command. Two additional
unlock write cycles are then followed by the chip erase
command, which in turn invokes the Embedded Erase
algorithm. The device does not require the system to
preprogram prior to erase. The Embedded Erase 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 16
shows the address and data requirements for the chip
erase command sequence.
When the Embedded Erase algorithm is complete,
that bank 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, DQ2,
or RY/BY#. Refer to the Write Operation Status section for information on these status bits.
Any commands written during the chip erase operation
are ignored. However, note that a hardware reset immediately terminates the erase operation. Note that
November 24, 2003
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 16 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
that bank to the read mode. Note that the SecSi sector, autoselect, and CFI functions are unavailable
when the SecSi Sector is enabled. The system must
rewrite the command sequence and any additional addresses and commands.
The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3:
Sector Erase Timer). 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
bank returns to reading array data and addresses are
no longer latched. Note that while the Embedded
Erase operation is in progress, the system can read
data from the non-erasing bank. The system can de-

period during the sector erase command sequence.
The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program
algorithm.
Once the sector erase operation has begun, only the
Erase Suspend command is valid. All other commands are ignored. However, note that a hardware
reset immediately terminates the erase operation. If
that occurs, the sector erase command sequence
should be reinitiated once that bank has returned to
reading array data, to ensure data integrity.
When the Erase Suspend command is written during
the sector erase operation, the device requires a maximum of 20 µs to suspend the erase operation. However, when the Erase Suspend command is written
during the sector erase time-out, the device immediately terminates the time-out period and suspends the
erase operation. Addresses are “don’t-cares” when
writing the Erase suspend command.

Erase Operation
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. The bank address is required when writing
this command. This command is valid only during the
sector erase operation, including the 80 µs time-out
50
After the erase operation has been suspended, the
bank enters the erase-suspend-read mode. The system can read data from or program data to any sector
not selected for erasure. (The device “erase suspends” all sectors selected for erasure.) Reading at
any address within erase-suspended sectors produces status information on 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 information on these status bits.
After an erase-suspended program operation is complete, the bank returns to the erase-suspend-read
mode. The system can determine the status of the
program operation using the 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. The device
allows reading autoselect codes even at addresses
within erasing sectors, since the codes are not stored
in the memory array. When the device exits the autoselect mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation.
Refer to the Autoselect Command Sequence sections
for details.
To resume the sector erase operation, the system
must write the Erase Resume command (address bits
are don’t care). The bank address of the erase-suspended bank is required when writing this command.
Further writes of the Resume command are ignored.
Another Erase Suspend command can be written after
the chip has resumed erasing.
Password Program Command
The Password Program Command permits programming the password that is used as part of the hardware protection scheme. The actual password is
64-bits long. Four Password Program commands are
required to program the password. The system must
enter the unlock cycle, password program command
(38h) and the program address/data for each portion
Am70PDL127CDH/Am70PDL129CDH
November 24, 2003
A D V A N C E
I N F O R M A T I O N
of the password when programming. There are no provisions for entering the 2-cycle unlock cycle, the password program command, and all the password data.
There is no special addressing order required for programming the password. Also, when the password is
undergoing programming, Simultaneous Operation is
disabled. Read operations to any memory location will
return the programming status. Once programming is
complete, the user must issue a Read/Reset command to return the device to normal operation. Once
the Password is written and verified, the Password
Mode Locking Bit must be set in order to prevent verification. The Password Program Command is only capable of programming “0”s. Programming a “1” after a
cell is programmed as a “0” results in a time-out by the
Embedded Program Algorithm™ with the cell remaining as a “0”. The password is all ones when shipped
from the factory. All 64-bit password combinations are
valid as a password.
Password Verify Command
The Password Verify Command is used to verify the
Password. The Password is verifiable only when the
Password Mode Locking Bit is not programmed. If the
Password Mode Locking Bit is programmed and the
user attempts to verify the Password, the device will always drive all F’s onto the DQ data bus.
The Password Verify command is permitted if the
SecSi sector is enabled. Also, the device will not operate in Simultaneous Operation when the Password
Verify command is executed. Only the password is returned regardless of the bank address. The lower two
address bits (A1-A0) are valid during the Password
Verify. Writing the Read/Reset command returns the
device back to normal operation.
Password Protection Mode Locking Bit
Program Command
The Password Protection Mode Locking Bit Program
Command programs the Password Protection Mode
Locking Bit, which prevents further verifies or updates
to the Password. Once programmed, the Password
Protection Mode Locking Bit cannot be erased! If the
Password Protection Mode Locking Bit is verified as
program without margin, the Password Protection
Mode Locking Bit Program command can be executed
to improve the program margin. Once the Password
Protection Mode Locking Bit is programmed, the Persistent Sector Protection Locking Bit program circuitry
is disabled, thereby forcing the device to remain in the
Password Protection mode. Exiting the Mode Locking
Bit Program command is accomplished by writing the
Read/Reset command.
November 24, 2003
Persistent Sector Protection Mode
Locking Bit Program Command
The Persistent Sector Protection Mode Locking Bit
Program Command programs the Persistent Sector
Protection Mode Locking Bit, which prevents the Password Mode Locking Bit from ever being programmed.
If the Persistent Sector Protection Mode Locking Bit is
verified as programmed without margin, the Persistent
Sector Protection Mode Locking Bit Program Command should be reissued to improve program margin.
By disabling the program circuitry of the Password
Mode Locking Bit, the device is forced to remain in the
Persistent Sector Protection mode of operation, once
this bit is set. Exiting the Persistent Protection Mode
Locking Bit Program command is accomplished by
writing the Read/Reset command.
SecSi Sector Protection Bit Program
Command
The SecSi Sector Protection Bit Program Command
programs the SecSi Sector Protection Bit, which prevents the SecSi sector memory from being cleared. If
the SecSi Sector Protection Bit is verified as programmed without margin, the SecSi Sector Protection
Bit Program Command should be reissued to improve
program margin. Exiting the VCC -level SecSi Sector
Protection Bit Program Command is accomplished by
writing the Read/Reset command.
PPB Lock Bit Set Command
The PPB Lock Bit Set command is used to set the
PPB Lock bit if it is cleared either at reset or if the
Password Unlock command was successfully executed. There is no PPB Lock Bit Clear command.
Once the PPB Lock Bit is set, it cannot be cleared unless the device is taken through a power-on clear or
the Password Unlock command is executed. Upon setting the PPB Lock Bit, the PPBs are latched into the
DYBs. If the Password Mode Locking Bit is set, the
PPB Lock Bit status is reflected as set, even after a
power-on reset cycle. Exiting the PPB Lock Bit Set
command is accomplished by writing the Read/Reset
command (only in the Persistent Protection Mode).
DYB Write Command
The DYB Write command is used to set or clear a DYB
for a given sector. The high order address bits
A22-A12 for PDL127 and (A21–A12) for PDL129H are
issued at the same time as the code 01h or 00h on
DQ7-DQ0. All other DQ data bus pins are ignored during the data write cycle. The DYBs are modifiable at
any time, regardless of the state of the PPB or PPB
Lock Bit. The DYBs are cleared at power-up or hardware reset. Exiting the DYB Write command is accomplished by writing the Read/Reset command.

I N F O R M A T I O N
Password Unlock Command
The Password Unlock command is used to clear the
PPB Lock Bit so that the PPBs can be unlocked for
modification, thereby allowing the PPBs to become accessible for modification. The exact password must be
entered in order for the unlocking function to occur.
This command cannot be issued any faster than 2 µs
at a time to prevent a hacker from running through all
64-bit combinations in an attempt to correctly match a
password. If the command is issued before the 2 µ s
execution window for each portion of the unlock, the
command will be ignored.
Once the Password Unlock command is entered, the
RY/BY# indicates that the device is busy. Approximately 1 µs is required for each portion of the unlock.
Once the first portion of the password unlock completes (RY/BY# is not low or DQ6 does not toggle
when read), the next part of the password is written.
The system must thus monitor RY/BY# or the status
bits to confirm when to write the next portion of the
password. Seven cycles are required to successfully
clear the PPB Lock Bit.
determine whether the PPB has been erased with
margin. If the PPBs has been erased without margin,
the erase command should be reissued to improve the
program margin.
It is the responsibility of the user to preprogram all
PPBs prior to issuing the All PPB Erase command. If
the user attempts to erase a cleared PPB, over-erasure may occur making it difficult to program the PPB
at a later time. Also note that the total number of PPB
program/erase cycles is limited to 100 cycles. Cycling
the PPBs beyond 100 cycles is not guaranteed.
DYB Write Command
The DYB Write command is used for setting the DYB,
which is a volatile bit that is cleared at reset. There is
one DYB per sector. If the PPB is set, the sector is protected regardless of the value of the DYB. If the PPB is
cleared, setting the DYB to a 1 protects the sector from
programs or erases. Since this is a volatile bit, removing power or resetting the device will clear the DYBs.
The bank address is latched when the command is
written.
PPB Program Command
PPB Lock Bit Set Command
The PPB Program command is used to program, or
set, a given PPB. Each PPB is individually programmed (but is bulk erased with the other PPBs).
The specific sector address (A21–A12) are written at
the same time as the program command 60h with A6
= 0. If the PPB Lock Bit is set and the corresponding
PPB is set for the sector, the PPB Program command
will not execute and the command will time-out without
programming the PPB.
The PPB Lock Bit set command is used for setting the
DYB, which is a volatile bit that is cleared at reset.
There is one DYB per sector. If the PPB is set, the sector is protected regardless of the value of the DYB. If
the PPB is cleared, setting the DYB to a 1 protects the
sector from programs or erases. Since this is a volatile
bit, removing power or resetting the device will clear
the DYBs. The bank address is latched when the command is written.
After programming a PPB, two additional cycles are
needed to determine whether the PPB has been programmed with margin. If the PPB has been programmed without margin, the program command
should be reissued to improve the program margin.
Also note that the total number of PPB program/erase
cycles is limited to 100 cycles. Cycling the PPBs beyond 100 cycles is not guaranteed.
PPB Status Command
The PPB Program command does not follow the Embedded Program algorithm.
PPB Lock Bit Status Command
The programming of the PPB Lock Bit for a given sector can be verified by writing a PPB Lock Bit status verify command to the device.
Sector Protection Status Command
All PPB Erase Command
The All PPB Erase command is used to erase all
PPBs in bulk. There is no means for individually erasing a specific PPB. Unlike the PPB program, no specific sector address is required. However, when the
PPB erase command is written all Sector PPBs are
erased in parallel. If the PPB Lock Bit is set the ALL
PPB Erase command will not execute and the command will time-out without erasing the PPBs. After
erasing the PPBs, two additional cycles are needed to
52
The programming of the PPB for a given sector can be
verified by writing a PPB status verify command to the
device.
The programming of either the PPB or DYB for a given
sector or sector group can be verified by writing a Sector Protection Status command to the device.
Note that there is no single command to independently
verify the programming of a DYB for a given sector
group.

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 18 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.
pleted the program or erase operation and DQ7 has
valid data, the data outputs on DQ15–DQ0 may be still
invalid. Valid data on DQ15–DQ0 will appear on successive read cycles.
Table 18 shows the outputs for Data# Polling on DQ7.
Figure 5 shows the Data# Polling algorithm. Figure 5
in the Flash AC Characteristics section shows the
Data# Polling timing diagram.
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 a bank 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 that bank 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 bank 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 400 µs, then the
bank 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.
When the system detects DQ7 has changed from the
complement to true data, it can read valid data at
DQ15–DQ0 on the following read cycles. Just prior to
the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with
DQ15–DQ0 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-

valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = “1” because
DQ7 may change simultaneously with DQ5.

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.
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 one of the banks is in the erase-suspend-read mode.
DQ6 also toggles during the erase-suspend-program
mode, and stops toggling once the Embedded Program algorithm is complete.
Table 18 shows the outputs for Toggle Bit I on DQ6.
Figure 6 shows the toggle bit algorithm. Figure 17 in
the “Flash AC Characteristics” section shows the toggle bit timing diagrams. Figure 18 shows the differences between DQ2 and DQ6 in graphical form. See
also the subsection on DQ2: Toggle Bit II.

Table 18 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 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#f1 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 approximately 400 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 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.

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#f1 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 18 to compare outputs for DQ2 and DQ6.
Figure 6 shows the toggle bit algorithm in flowchart
form, and the section “DQ2: Toggle Bit II” explains the
algorithm. See also the DQ6: Toggle Bit I subsection.
Figure 17 shows the toggle bit timing diagram. Figure
18 shows the differences between DQ2 and DQ6 in
graphical form.
Reading Toggle Bits DQ6/DQ2
Refer to Figure 6 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 the section on DQ5). If it is, the system should
then determine again whether the toggle bit is toggling, since the toggle bit may have stopped 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
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 6).
DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has
exceeded a specified internal pulse count limit. Under these
conditions DQ5 produces a “1,” 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.”
Under both these conditions, the system must write
the reset command to return to the read mode (or to
the erase-suspend-read mode if a bank 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.” 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 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 18 shows the status of DQ3 relative to the other
status bits.

Notes:
1. tHZ and tOZ are defined as the time at which the outputs
achieve the open circuit conditions and are not
referenced to output voltage levels.
2. At any given temperature and voltage condition, tHZ (Max) is
less than tLZ (Min) both for a given device and from device
interconnection.

t OHZ
t LZ
3. tOE (Max) is met only when OE# becomes enabled after tAA
(Max).
4. If invalid address signals shorter than min. tRC are
continuously repeated for over 4 us, the device needs a
normal read timing (tRC) or needs to sustain standby state
for min. tRC at least once in every 4 us.

Notes: Write Cycle
1. A write occurs during the overlap (tWP) of low CS#1s and low WE#. A write begins when CS#1s goes low and WE# goes low
with asserting UB# or LB# for single byte operation or simultaneously asserting UB# and LB# for double byte operation. A
write ends at the earliest transition when CS#1s goes high and WE# goes high. The tWP is measured from the beginning of
write to the end of write.
2. tCW is measured from the CS#1s going low to the end of write.
3. tAS is measured from the address valid to the beginning of write.
4. tWR is measured from the end of write to the address change. tWR is applied in case a write ends with CS#1s or WE# going high.

Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0 V VCC, 1,000,000 cycles. Additionally,
programming typicals assume checkerboard pattern. All values are subject to change.
2. Under worst case conditions of 90°C, VCC = 2.7 V, 1,000,000 cycles. All values are subject to change.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
program faster than the maximum program times listed.
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Tables
Table 16 for further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 1,000,000 cycles.

GENERAL DESCRIPTION (LV640M)
The Am29LV640MH is a 64 Mbit, 3.0 volt single power
supply flash memory device organized as 4,194,304
words. The device has an 8-bit/16-bit bus and can be
programmed either in the host system or in standard
EPROM programmers.
An access time of 110 ns is available. 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 (ACC) feature provides shorter programming times through increased
current on the WP#/ACC input. 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.
Hardware data protection measures include a low
V CC detector that automatically inhibits write operations during power transitions. The hardware sector
protection feature disables both program and erase
80
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 Write Protect (WP#) feature protects the first or
last sector by asserting a logic low on the WP#/ACC
pin. The protected sector will still be protected even
during accelerated programming.
The SecSi ™ (Secured Silicon) Sector provides a
128-word 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.

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.

3. If WP# = VIL, the first or last sector remains protected. If WP# = VIH, the first or last sector will be protected or unprotected as
determined by the method described in “Sector Group Protection and Unprotection”. All sectors are unprotected when shipped
from the factory (The SecSi Sector may be factory protected depending on version ordered.)
4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 2).
Requirements for Reading Array Data
To read array data from the outputs, the system must
drive the CE# and OE# pins to VIL. CE# is the power
control and selects the device. OE# is the output control and gates array data to the output pins. WE#
should remain at VIH.
The 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.
November 24, 2003
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 specifications 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 operation. 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. Address 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 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 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 sequences.
An erase operation can erase one sector, multiple sectors, 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 Characteristics section contains timing specification tables
and timing diagrams for write operations.
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. Refer to the Autoselect Mode and Autoselect Command Sequence sections 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.
Refer to the DC Characteristics table for the standby
current specification.
Write Buffer
Write Buffer Programming allows the system to write 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 primarily intended to allow faster manufacturing throughput
at the factory.
82
If the system asserts VHH on this pin, the device automatically enters the aforementioned Unlock Bypass
mode, temporarily unprotects any protected sectors,
and uses the higher voltage on the pin to reduce the
time required for program operations. The system
would use a two-cycle program command sequence
as required by the Unlock Bypass mode. Removing
VHH from the WP#/ACC pin returns the device to normal operation. Note that the WP#/ACC pin must not be
at VHH for operations other than accelerated programming, or device damage may result. In addition, no external pullup is necessary since the WP#/ACC pin has
internal pullup to VCC.
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables
this mode when addresses remain stable for t ACC +
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.

A D V A N C E
I N F O R M A T I O N
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 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.
November 24, 2003
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 circuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory.
Refer to the AC Characteristics tables for RESET# parameters 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.

Sector Group Protection and
Unprotection
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 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 24 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 the Autoselect Mode
section for details.

Write Protect (WP#)
The Write Protect function provides a hardware
method of protecting the first or last sector without
using VID. Write Protect is one of two functions provided by the WP#/ACC input.
START
If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the first
or last sector independently of whether those sectors
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 Characteristics”.
RESET# = VID
(Note 1)
Perform Erase or
Program Operations
RESET# = VIH
If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the first or last sector was previously set to be protected or unprotected using the
method described in “Sector Group Protection and
Unprotection”. Note: No external pullup is necessary
since the WP#/ACC pin has internal pullup to VCC.
Temporary Sector Group Unprotect
(Note: In this device, a sector group consists of four adjacent
sectors that are protected or unprotected at the same time
(see Table 4).
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 23 shows the timing
diagrams, for this feature.

SecSi (Secured Silicon) Sector Flash
Memory Region
ods, in addition to the standard programming command sequence. See Command Definitions.
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 128 words 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.
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.
AMD offers the device with the SecSi Sector either
fac t or y l ocke d or c u s t om e r l o ck abl e. T he fac tory-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 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, 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.
The SecSi sector address space in this device is allocated 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 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.

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
Am70PDL127CDH/Am70PDL129CDH
November 24, 2003

I N F O R M A T I O N
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 accept any write cycles. This protects data during VCC
power-up and power-down. The command register
and all internal program/erase circuits are disabled,
and the device resets to 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 V CC 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# = V IH during power up,
the device does not accept commands on the rising
edge of WE#. The internal state machine is automatically reset to the read mode on power-up.
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.
November 24, 2003
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
these documents.

COMMAND DEFINITIONS
Writing specific address and data commands or sequences into the command register initiates device operations. Tables 10 and 11 define 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
94
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
Am70PDL127CDH/Am70PDL129CDH
November 24, 2003
A D V A N C E
I N F O R M A T I O N
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 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 operation, or if the device is in the autoselect mode. See
the next section, Reset Command, for more information.
See also Requirements for Reading Array Data in the
Device Bus Operations section for more information.
The Read-Only Operations table provides the read parameters, and Figure 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 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.
November 24, 2003
Autoselect Command Sequence
The autoselect command sequence allows the host
system to read several identifier codes at specific addresses:
Identifier Code
A7:A0
(x16)
Manufacturer ID
00h
Device ID, Cycle 1
01h
Device ID, Cycle 2
0Eh
Device ID, Cycle 3
0Fh
SecSi Sector Factory Protect
03h
Sector Protect Verify
(SA)02h
Note: The device ID is read over three cycles. SA = Sector
Address
Tables 10 and 11 show the address requirements and
codes. 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:
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 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 issues the four-cycle Exit SecSi Sector command sequence. 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 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.
Word 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
Am70PDL127CDH/Am70PDL129CDH
95
A D V A N C E
I N F O R M A T I O N
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/byte program command sequence, respectively.
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 or DQ6. Refer to the Write Operation Status section for information on these status bits.
Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a
hardware reset immediately terminates the program
operation. The program command sequence should
be reinitiated once the device has returned to the read
mode, to ensure data integrity. Note that the ACC
function and unlock bypass modes are not available
when the SecSi Sector is enabled.
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 words 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. Tables 10 and 11 show 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.
96
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 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 word 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. The write-buffer-page is selected by address bits A MAX–A 4 . 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.
(This means Write Buffer Programming cannot be performed across multiple write-buffer pages. This also
means that Write Buffer Programming cannot be performed 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
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. 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.
command sequence must be written to reset the device for the next operation. Note that the full 3-cycle
Write-to-Buffer-Abort Reset command sequence is required when using Write-Buffer-Programming features
in Unlock Bypass mode.
The Write Buffer Programming Sequence can be
aborted in the following ways:
Accelerated Program
■ 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
November 24, 2003
The device offers accelerated program operations
through the WP#/ACC pin. When the system asserts
VHH on the WP#/ACC pin, the device automatically enters the Unlock Bypass mode. The system may then
write the two-cycle Unlock Bypass program command
sequence. The device uses the higher voltage on the
WP#/ACC pin to accelerate the operation. Note that
the WP#/ACC pin must not be at V HH for operations
other than accelerated programming, or device damage may result. In addition, no external pullup is necessary since the WP#/ACC pin has internal pullup to
VCC.
Figure 5 illustrates the algorithm for the program operation. Refer to the Erase and Program Operations
table in the AC Characteristics section for parameters,
and Figure 17 for timing diagrams.

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.

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. Note that the SecSi Sector,
autoselect, and CFI functions are unavailable when an
program operation is in progress.
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 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 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. Tables 10 and
11 show the address and data requirements for the
chip erase command sequence.
100
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. Note that the
SecSi Sector, autoselect, and CFI functions are unavailable when an erase operation is in progress.
Figure 7 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters,
and Figure 19 section for timing diagrams.

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 information on these status bits.
Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector
erase command sequence is initiated by writing two
unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and
the sector erase command. Tables 10 and 11 show 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.

The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3:
Sector Erase Timer.). The time-out begins from the rising edge of the final WE# pulse in the command
sequence.
Erase Suspend/Erase Resume
Commands
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 Operation Status section for information on these status bits.
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.
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.
When the Erase Suspend command is written during
the sector erase operation, the device requires a maximum of 20 (typical 5 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.
Figure 7 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations tables in the AC Characteristics section for parameters,
and Figure 19 section for timing diagrams.
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.

information.
In the erase-suspend-read mode, the system can also

To resume the sector erase operation, the system
must write the Erase Resume command. The address
of the erase-suspended sector is required when writing this command. Further writes of the Resume command are ignored. Another Erase Suspend command

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 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 12 shows the outputs for Data# Polling on DQ7.
Figure 8 shows the Data# Polling algorithm. Figure 20
in the AC Characteristics section 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.
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
the status or valid data. Even if the device has completed the program or erase operation and DQ7 has

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

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.
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 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 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.
104
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 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 Program algorithm is complete.
Table 12 shows the outputs for Toggle Bit I on DQ6.
Figure 9 shows the toggle bit algorithm. Figure 21 in
the “AC Characteristics” section shows the toggle bit
timing diagrams. Figure 22 shows the differences between DQ2 and DQ6 in graphical form. See also the
subsection on DQ2: Toggle Bit II.

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 12 to compare outputs for DQ2 and DQ6.

Figure 9.
Toggle Bit Algorithm
Refer to Figure 9 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 the section on DQ5). If it is, the system should
then determine again whether the toggle bit is toggling, since the toggle bit may have stopped 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
the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform
November 24, 2003

I N F O R M A T I O N
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 9).
DQ5: Exceeded Timing Limits
DQ5 indic ates 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 com-

mand. 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. 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 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 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”.

Comments
Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0 V VCC. Programming specifications assume that
all bits are programmed to 00h.
2. Maximum values are measured at VCC = 3.0 V, worst case temperature. Maximum values are valid up to and including 100,000
program/erase cycles.
3. Word programming specification is based upon a single word programming operation not utilizing the write buffer.
4. For 1-16 words programmed in a single write buffer programming operation.
5. Effective write buffer specification is calculated on a per-word basis for a 16-word write buffer operation.
6. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
7. System-level overhead is the time required to execute the command sequence(s) for the program command. See Tables 12 and
11 for further information on command definitions.
8. The device has a minimum erase and program cycle endurance of 100,000 cycles.
