GENERAL DESCRIPTION
The KH29LV800C T/B is a 8-mega bit Flash memory
organized as 1M bytes of 8 bits or 512K words of 16
bits. MXIC's Flash memories offer the most cost-effec-
tive and reliable read/write non-volatile random access
memor y. The KH29LV800C T/B is packaged in 48-pin
TSOP. It is designed to be reprogrammed and erased in
system o r in standard EPROM pro grammers.
The standard KH29LV800C T/B offers access time as
fast as 55ns, allowing o peratio n of high-speed micropro-
cessors without wait states. To eliminate bus conten-
tion, the KH29LV800C T/B has separate chip enable
(CE#) and output enable (OE#) controls.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and pro gramming. The
KH29LV800C T/B uses a co mmand register to manage
this functio nality . The command register allows for 100%
TTL level control inputs and fixed power supply levels
during erase and pro gramming, while maintaining maxi-
mum EPR OM compatibility.
MXIC Flash technology reliably stores memory contents
even after 100,000 erase and pro gram cycles. The MXIC
cell is designed to optimize the erase and programming
mechanisms. In addition, the combination of advanced
tunnel oxide processing and low internal electric fields
for erase and program operations produces reliable cy-
cling. The KH29LV800C T/B uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up pro-
tection is proved for stresses up to 100 milliamperes on
address and data pin from -1V to VCC + 1V.

REV. 1.2, DEC. 09, 2005
AUTOMATIC PROGRAMMING
The KH29LV800C T/B is b yte progr ammable using the
Automatic Pro gramming algo rithm. The Auto matic Pro-
gramming algorithm makes the external system do not
need to have time out sequence nor to verify the data
programmed. The typical chip programming time at room
temperature o f the KH29L V800C T/B is less than 10 sec-
onds.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm requires the
user to only write program set-up commands (including
2 unlock write cycle and A0H) and a program command
(program data and address). The de vice automatically
times the programming pulse width, provides the pro-
gram v erificatio n, and counts the number of sequences.
A status bit similar to DATA# polling and a status bit
to ggling between consecutive read cycles, pro vide feed-
back to the user as to the status of the programming
operatio n. Refer to write operation status, table 8, for more
inf o rmatio n on these status bits.
AUTOMATIC CHIP ERASE
The entire chip is bulk erased using 10 ms erase pulses
according to MXIC's Automatic Chip Erase algorithm.
Typical erasure at ro om temperature is acco mplished in
less than 25 second. The Automatic Erase algorithm
automatically programs the entire array prior to electri-
cal erase. The timing and verificatio n of electrical erase
are controlled internally within the device.
AUTOMATIC SECTOR ERASE
The KH29LV800C T/B is sector(s) erasable using MXIC's
Auto Sector Erase algorithm. The Automatic Sector
Erase algorithm automatically programs the specified
secto r(s) prio r to electrical erase . The timing and verifi-
catio n of electrical erase are co ntrolled internally within
the device. An erase operation can erase one sector,
multiple sectors, or the entire device.
AUTOMATIC ERASE ALGORITHM
MXIC's A utomatic Erase algorithm requires the user to
write commands to the command register using stan-
dard micro processo r write timings. The device will auto-
matically pre-progr am and verify the entire arra y. Then
the device automatically times the erase pulse width,
provides the erase verification, and counts the number
of sequences. A status bit toggling between consecu-
tive read cycles provides feedback to the user as to the
status of the erasing operation.
Register contents serve as inputs to an internal state-
machine which controls the erase and programming cir-
cuitry. During write cycles, the co mmand register inter-
nally latches address and data needed for the program-
ming and erase operations. During a system write cycle,
addresses are latched on the falling edge, and data are
latched on the rising edge of WE# or CE#, whichever
happens first.
MXIC's Flash technology combines years of EPROM
e xperience to pro duce the highest le v els of quality, reli-
ability, and cost effectiveness. The KH29LV800C T/B
electrically erases all bits simultaneously using Fowler-
No rdheim tunneling. The bytes are programmed by us-
ing the EPROM programming mechanism of hot elec-
tron injection.
During a program cycle, the state-machine will control
the program sequences and command register will not
respond to any command set. During a Sector Erase
cycle, the command register will only respond to Erase
Suspend command. After Erase Suspend is completed,
the device stays in read mode. After the state machine
has completed its task, it will allow the command regis-
ter to respond to its full command set.
AUTOMATIC SELECT
The auto select mode provides manufacturer and de-
vice identification, and sector protection verification,
thro ugh identifier co des o utput on Q7~Q0. This mo de is
mainly adapted for programming equipment on the de-
vice to be programmed with its programming algorithm.
When programming by high voltage method, automatic
select mode requires VID (11.5V to 12.5V) on address
pin A9 and other address pin A6, A1 and A0 as referring
to Table 3. In addition, to access the automatic select
codes in-system, the host can issue the automatic se-
lect co mmand thro ugh the command register witho ut re-
quiring VID, as shown in table 5.
To verify whether or not secto r being pro tected, the sec-

bits, as shown in table 3, are do n't care. Once all neces-
sary bits have been set as required, the programming
equipment may read the corresponding identifier code on

KH29L V800C T/B is capable o f operating in the CFI mode.
This mode all the host system to determine the manu-
facturer o f the device such as o perating parameters and
co nfiguratio n. Two co mmands are required in CFI mo de.
Query command of CFI mode is placed first, then the
Reset co mmand exits CFI mo de. These are described in
Table 6.
The single cycle Query command is valid only when the
device is in the Read mode, including Erase Suspend,
Standby mode, and Read ID mode; however, it is ig-
nored otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, or read ID mode.
The command is valid only when the device is in the
CFI mode.

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. Standard
microprocessor read cycles that assert valid address
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.
WRITE COMMANDS/COMMAND SEQUENCES
To program data to the device or erase sectors of memory
, the system must driv e WE# and CE# to VIL, and OE#
to VIH.
An erase o peration can erase one sector, multiple secto rs
, o r the entire device. Table indicates the address space
that each sector occupies. A "sector address" consists
of the address bits required to uniquely select a sector .
The "Writing specific address and data commands or
sequences into the command register initiates device
operations. Table 1 defines the v alid register command
sequences. Writing inco rrect address and data values o r
writing them in the improper sequence resets the device
to reading array data. Section has details on erasing a
sector or the entire chip, or suspending/resuming the
erase operation.
After the system writes the autoselect command
sequence, the device enters the autoselect mode. The
system can then read autoselect codes from the internal
register (which is separate from the memory array) on
Q7-Q0. Standard read cycle timings apply in this mode.
Refer to the Autoselect Mode and Auto select Co mmand
Sequence sectio n fo r more info rmatio n.
ICC2 in the DC Characteristics table represents the
active current specification f or the write mo de . The "A C
Characteristics" section contains timing specification
table and timing diagrams fo r write operations.
STANDBY MODE
When using both pins of CE# and RESET#, the device
enter CMOS Standby with both pins held at Vcc ± 0.3V.
If CE# and RESET# are held at VIH, but not within the
range of VCC ± 0.3V, the device will still be in the standby
mo de, but the standby current will be larger. During Auto
Algo rithm o peration, Vcc active current (Icc2) is required
even CE# = "H" until the operation is completed. The
device can be read with standard access time (tCE) from
either of these standby modes, before it is ready to read
data.
OUTPUT DISABLE
With the OE# input at a logic high level (VIH), output
fro m the devices are disabled. This will cause the output
pins to be in a high impedance state.
RESET# OPERATION
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, tri-
states 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 operatio n that was interrupted sho uld 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±0.3V, the device draws
CMOS standby current (ICC4). If RESET# is held at VIL
but not within VSS±0.3V, the standby current will be
greater.
The RESET# pin ma y be tied to system reset circuitry.

If RESET# is asserted during a program or erase
o peratio n, the RY/BY# pin remains a "0" (b usy) until the
internal reset operation is complete, which requires a
time of tREADY (during Embedded Algorithms). The
system can thus mo nito r R Y/BY# to determine whether
the reset operation is complete. If RESET# is asserted

system can read data tRH after the RESET# pin returns
to VIH.
Refer to the AC Characteristics tables for RESET#
parameters and to Figure 22 f or the timing diagram.
READ/RESET COMMAND
The read or reset o peration is initiated by writing the read/
reset command sequence into the command register.
Micro processor read cycles retrie ve array data. The de-
vice remains enabled fo r reads until the co mmand regis-
ter co ntents are altered.
If pro gram-f ail or erase-fail happen, the write o f F0H will
reset the device to abort the operation. A valid com-
mand must then be written to place the device in the
desired state.
SILICON-ID READ COMMAND
Flash memories are intended for use in applications where
the lo cal CPU alters memo ry co ntents. As such, manu-
facturer and device co des must be accessible while the
device resides in the target system. PROM program-
mers typically access signature codes by raising A9 to
a high vo ltage (VID). However , multiplexing high voltage
onto address lines is not generally desired system de-
sign practice.
The KH29L V800C T/B contains a Silicon-ID-Read opera-
tio n to supple traditional PROM pro gramming metho dol-
o gy. The o peratio n is initiated by writing the read silico n
ID co mmand sequence into the command register. Fo l-
lowing the command wr ite, a read cycle with A1=VIL,
A0=VIL retrieves the manufacturer co de of C2H/00C2H.
A read cycle with A1=VIL, A0=VIH returns the device
co de of DAH/22D AH fo r KH29LV800CT, 5BH/225BH fo r
KH29LV800CB.
SET-UP AUTOMATIC CHIP/SECTOR ERASE
COMMANDS
Chip erase is a six-bus cycle operation. There are two
"unlo c k" write cycles. These are f o llo wed by writing the
"set-up" co mmand 80H. Two mo re "unlock" write cycles
are then followed by the chip erase command 10H or
secto r erase co mmand 30H.
The Auto matic Chip Erase does not require the device to
be entirely pre-pro grammed prior to ex ecuting the Auto-
matic Chip Erase. Upon executing the Automatic Chip
Erase, the device will automatically program and verify
the entire memo ry fo r an all-zero data pattern. When the
device is automatically verified to co ntain an all-zero pat-
tern, a self-timed chip erase and verify begin. The erase
and verify operatio ns are completed when the data on Q7
is "1" at which time the device returns to the Read mode.
The system is no t required to pro vide any co ntro l o r tim-
ing during these operations.
When using the Automatic Chip Erase algor ithm, note
that the erase auto matically terminates when adequate
erase margin has been achieved for the memory array
(no erase verificatio n command is required).
If the Erase o peratio n was unsuccessful, the data o n Q5
is "1" (see Table 8), indicating the erase operation ex-
ceed internal timing limit.
The automatic erase begins o n the rising edge o f the last
WE# o r CE# pulse, whiche ver happens first in the co m-
mand sequence and terminates when the data on Q7 is
"1" at which time the device returns to the Read mode,
o r the data on Q6 sto ps toggling fo r two co nsecutive read
cycles at which time the device returns to the Read mode.

READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to re-
trieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The sys-
tem can read array data using the standard read tim-
ings, except that if it reads at an address within erase-
suspended sectors, the device outputs status data. Af-
ter completing a programming operation in the Erase
Suspend mode, the system may once again read array
data with the same exception. See Erase Suspend/Erase
Resume Commands for more information on this mode.
The system must issue the reset command to re-en-
able the device for reading array data if Q5 goes high, or
while in the autoselect mode. See the "Reset Command"
section, next.
RESET COMMAND
Writing the reset command to the device resets the de-
vice to reading array data. Address bits are don't care
for this command.
The reset command may be written between the se-
quence cycles in an erase command sequence before
erasing begins. This resets the device to reading arra y
data. Once erasure begins, however , the device igno res
reset commands until the operation is complete.
The reset command may be written between the se-
quence cycles in a program command sequence before
programming begins. This resets the device to reading
array data (also applies to programming in Erase Sus-
pend mode). Once programming begins, however, the
device ignores reset commands until the operation is
complete.
The reset command may be written between the se-
quence cycles in an SILICON ID READ command se-
quence. Once in the SILICON ID READ mode, the reset
command must be written to return to reading array data
(also applies to SILICON ID READ during Erase Sus-
pend).
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to read-
ing array data (also applies during Erase Suspend).

SECTOR ERASE COMMANDS
The Automatic Sector Erase does not require the de-
vice to be entirely pre-programmed prior to executing
the Automatic Sector Erase Set-up command and Au-
tomatic Sector Erase command. Upon executing the
Automatic Sector Erase command, the device will auto-
matically program and verify the sector(s) memory for
an all-zero data pattern. The system is not required to
provide any control or timing during these operations.
When the sector(s) is automatically verified to contain
an all-zero pattern, a self-timed sector erase and verify
begin. The erase and verify operations are complete
when either the data on Q7 is "1" at which time the de-
vice returns to the Read mode, or the data on Q6 stops
toggling for two consecutive read cycles at which time
the device returns to the Read mode. The system is not
required to provide any control or timing during these
operations.
When using the Automatic sector Erase algorithm, note
that the erase automatically terminates when adequate
erase margin has been achieved for the memory array
(no erase verification command is required). Sector
erase is a six-bus cycle operation. There are two "un-
lock" write cycles. These are followed by writing the
set-up command 80H. Two more "unlock" write cycles
are then followed by the sector erase command 30H.
The secto r address is latched on the falling edge o f WE#
or CE#, whichever happens later, while the command
(data) is latched on the rising edge of WE# or CE#,
whichever happens first. Sector addresses selected are
loaded into internal register on the sixth falling edge of
WE# or CE#, whichever happens later. Each succes-
sive secto r load cycle started by the falling edge of WE#
or CE#, whichever happens later must begin within 50us
fro m the rising edge of the preceding WE# or CE#, which-
ever happens first. Otherwise, the loading period ends
and internal auto secto r erase cycle starts . (Mo nito r Q3
to determine if the sector erase timer window is still open,
see section Q3, Sector Erase Timer.) Any command other
than Sector Erase (30H) or Erase Suspend (B0H) during
the time-out period resets the device to read mode.
ERASE SUSPEND
This command only has meaning while the state ma-
chine is executing Automatic Sector Erase operation,
and therefore will only be responded during Automatic
Secto r Erase operation. When the Erase Suspend Com-
mand is issued during the sector erase operation, the
device requires a maximum 20us to suspend the sector
erase o peration. However , when the Erase Suspend com-
mand is written during the sector erase time-out, the
device immediately terminates the time-out period and
suspends the erase operation. After this command has
been executed, the command register will initiate erase
suspend mode. The state machine will return to read
mo de automatically after suspend is ready . At this time,
state machine only allows the command register to re-
spond to Erase Resume, program data to , or read data
from any sector not selected for erasure.
The system can determine the status of the program
operation using the Q7 or Q6 status bits, just as in the
standard program operation. After an erase-suspend pro-
gram operation is complete, the system can once again
read array data within non-suspended sectors.
ERASE RESUME
This command will cause the command register to clear
the suspend state and return back to Sector Erase mode
but only if an Erase Suspend command was previously
issued. Erase Resume will not have any effect in all
other conditions. Another Erase Suspend command can
be written after the chip has resumed erasing. However ,
a delay time must be required after the erase resume
command (1.5ms for KH29LV800C T/B), if the system
implements an endless erase suspend/resume loop, or
the number of erase suspend/resume is exceeded 1024
times. The erase times will be expended if the erase
behavior always be suspended. (Please refer to MXIC
Flash Application Note for details.)
WORD/BYTE PROGRAM COMMAND SEQUENCE
The device programs one byte of data for each program
operation. The command sequence requires four bus
cycles, and 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 generates the program pulses and verifies
the programmed cell margin. Table 1 shows the address
and data requirements for the byte program command
sequence.
When the Embedded Program algorithm is complete,
the device then returns to reading array data and
addresses are no longer latched. The system can

WRITE OPERATION STATUS
The device provides several bits to determine the sta-
tus of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/
BY#. Table 10 and the following subsections describe
the functions of these bits. Q7, RY/BY#, and Q6 each
offer a method for determining whether a program or erase
operation is complete or in progress. These three bits
are discussed first.
Q7: Data# Polling
The D ATA# po lling bit, Q7, indicates to the ho st system
whether an Automatic Algorithm is in progress or com-
pleted, or whether the device is in Erase Suspend. DAT A#
po lling is valid after the rising edge o f the final WE# pulse
in the program or erase command sequence.
During the Automatic Program algorithm, the device out-
puts on Q7 the complement of the datum programmed
to Q7. This Q7 status also applies to pro gramming dur-
ing Erase Suspend. When the Auto matic Pro gram algo-
rithm is complete, the device outputs the datum pro-
gr ammed to Q7. The system must provide the pro gram
address to read valid status information on Q7. If a pro-
gram address falls within a pro tected secto r, DA TA# poll-
ing on Q7 is active for approximately 1 us, then the de-
vice returns to reading array data.
During the Auto matic Erase algorithm, DAT A# po lling pro-
duces a "0" on Q7. When the Automatic Erase algo-
determine the status of the program operation by using
Q7, Q6, or RY/BY#. See "Write Operation Status" for
information on these status bits.
Any commands written to the device during the Em-
bedded Program Algorithm are ignored. Note that a
hardware reset immediately terminates the programming
operation. The Byte Program command sequence should
be reinitiated once the device has reset to reading array
data, to ensure data integrity.
Programming is allowed in any sequence and across
sector boundaries. A bit cannot be programmed from a
"0" back to a "1". Attempting to do so may halt the
operation and set Q5 to "1" , or cause the DATA# polling
algorithm to indicate the operation was successful.
However, a succeeding read will show that the data is
still "0". Only erase operations can convert a "0" to a
"1".
rithm is co mplete, o r if the device enters the Erase Sus-
pend mo de, D ATA# polling produces a "1" o n Q7. This is
analogous to the complement/true datum out-put de-
scribed for the Automatic Program algorithm: the erase
function changes all the bits in a sector to "1" prior to
this, the device outputs the "complement," or "0". The
system must provide an address within any of the sec-
tors selected for erasure to read valid status information
on Q7.
After an erase command sequence is written, if all sec-
to rs selected fo r erasing are pro tected, DATA# polling on
Q7 is active for approximately 100 us, then the device
returns to reading array data. If not all selected sectors
are protected, the Automatic Erase algorithm erases the
unprotected sectors, and ignores the selected sectors
that are protected.
When the system detects Q7 has changed from the
complement to true data, it can read valid data at Q7-Q0
on the following read cycles. This is because Q7 may
change asynchronously with Q0-Q6 while Output En-
ab le (OE#) is asserted low .
RY/BY# : Ready/Busy
The RY/BY# is a dedicated, open-drain output pin that
indicates whether an Automatic Erase/Program algorithm
is in progress or complete. The RY/BY# status is valid
after the rising edge o f the final WE# o r CE#, whichever
happens first, in the command sequence. Since RY/BY#
is an open-drain output, several RY/BY# pins can be
tied to gether in par allel with a pull-up resisto r 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 de-
vice is ready to read array data (including during the
Erase Suspend mode), or is in the standby mode.
Table 8 shows the outputs for RY/BY# during write op-
eration.
Q6:Toggle BIT I
To ggle Bit I o n Q6 indicates whether an A utomatic Pro-
gram 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 o f the final WE# o r CE#, whichever
17
P/N:PM1222
KH29LV800C T/B
REV. 1.2, DEC. 09, 2005
During an Automatic Program or Erase algorithm opera-
tion, successive read cycles to any address cause Q6
to toggle. The system may use either OE# or CE# to
co ntrol the read cycles. When the o peratio n is complete,
Q6 stops toggling.
After an erase command sequence is written, if all sec-
tors selected for erasing are protected, Q6 toggles and
returns to reading array data. If not all selected sectors
are protected, the Automatic Erase algorithm erases the
unprotected sectors, and ignores the selected sectors
that are protected.
The system can use Q6 and Q2 together to determine
whether a sector is actively erasing or is erase sus-
pended. When the device is actively erasing (that is, the
Automatic Erase algorithm is in progress), Q6 toggling.
When the device enters the Erase Suspend mode, Q6
stops toggling. However, the system must also use Q2
to determine which sectors are erasing or erase-sus-
pended. Alternatively, the system can use Q7.
If a program address f alls within a protected sector , Q6
toggles for approximately 2 us after the program com-
mand sequence is written, then returns to reading array
data.
Q6 also toggles during the erase-suspend-program mode,
and stops toggling once the Automatic Program algo-
rithm is complete.
Table 8 shows the outputs f or To ggle Bit I on Q6.
Q2:Toggle Bit II
The "To ggle Bit II" o n Q2, when used with Q6, indicates
whether a par ticular sector is actively erasing (that is,
the Automatic Erase algorithm is in process), or whether
that sector is erase-suspended. Toggle Bit II is valid
after the rising edge o f the final WE# o r CE#, whichever
happens first, in the command sequence.
Q2 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 Q2 cannot distinguish whether the sector
is actively erasing or is erase-suspended. Q6, by com-
parison, indicates whether the device is actively eras-
ing, or is in Erase Suspend, but cannot distinguish which
sectors are selected for erasure. Thus , bo th status bits
are required for sectors and mode information. Refer to
Table 8 to co mpare outputs for Q2 and Q6.
Reading Toggle Bits Q6/ Q2
Whenever the system initially begins reading toggle bit
status, it must read Q7-Q0 at least twice in a row to
determine whether a to ggle 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
co mpleted the pro gram o r erase o peratio n. The system
can read array data on Q7-Q0 on the following read cycle.
How ever, if after the initial two read cycles , the system
determines that the toggle bit is still toggling, the sys-
tem also should note whether the value of Q5 is high
(see the section on Q5). 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 Q5 went
high. If the toggle bit is no longer toggling, the device
has successfully completed the program or erase op-
eration. If it is still toggling, the device did not complete
the operation successfully, and the system must write
the reset command to return to reading array data.
The remaining scenario is that system initially determines
that the toggle bit is toggling and Q5 has not gone high.
The system may continue to monitor the toggle bit and
Q5 through successive read cycles, determining the sta-
tus as described in the previous paragraph. Alterna-
tively, it may choose to perform other system tasks. In
this case, the system m ust start at the beginning o f the
algorithm when it returns to determine the status of the
operation.
Q5
Exceeded Timing Limits
Q5 will indicate if the program or erase time has ex-
ceeded the specified limits (internal pulse count). Under
these conditions Q5 will produce a "1". This time-out
condition indicates that the program or erase cycle was
not successfully completed. Data# Polling and Toggle
Bit are the only operating functions of the device under
this condition.

TEMPORARY SECTOR UNPROTECTED
This feature allows temporary unprotected of previously
pro tected secto r to change data in-system. The Tempo-
rary Sector Unprotected mode is activated by setting
the RESET# pin to VID(11.5V -12.5V). During this mode,
formerly protected sectors can be programmed or erased
as un-protected sector. Once VID is remove from the
RESET# pin, all the previously protected sectors are
protected again.
SECTOR PROTECTION
The KH29LV800C T/B features hardware secto r pro tec-
tion. This feature will disable both program and erase
operations for these sectors protected. To activate this
mode, the programming equipment must force VID on
address pin A9 and OE# (suggest VID = 12V). Pro-
gramming of the protection circuitry begins on the falling
edge of the WE# pulse and is ter minated on the r ising
edge. Please refer to sector protect algorithm and wave-
form.
To verify pro gramming o f the protection circuitry , the pro-
gramming equipment must fo rce VID o n address pin A9
( with CE# and OE# at VIL and WE# at VIH). When
A1=VIH, A0=VIL, A6=VIL, it will produce a logical "1"
code at de vice output Q0 f or a pro tected sector . Other-
wise the device will produce 00H for the unprotected
sector. In this mo d e , the addresses , except f or A1, are

remain low until the time-o ut is complete. DATA# po lling
and T o ggle Bit are valid after the initial secto r erase co m-
mand sequence.
If DATA# polling or the Toggle Bit indicates the device
has been written with a valid erase command, Q3 may
be used to determine if the sector erase timer window is
still open. If Q3 is high ("1") the internally controlled
erase cycle has begun; attempts to write subsequent
commands to the device will be ignored until the erase
o peratio n is co mpleted as indicated by DATA# po lling o r
Toggle Bit. If Q3 is low ("0"), the device will accept
additional sector erase commands. To insure the com-
mand has been accepted, the system software should
check the status of Q3 prior to and following each sub-
sequent sector erase command. If Q3 were high on the
second status check, the command may not have been
accepted.
DATA PROTECTION
The KH29LV800C T/B is designed to offer protection
against accidental erasure or programming caused by
spurious system level signals that may exist during power
transition. During power up the device automatically re-
sets the state machine in the Read mode. In addition,
with its control register architecture, alteration of the
memory contents only occurs after successful comple-
tion of specific command sequences. The device also
incorpo rates several features to prevent inadvertent write
cycles resulting from VCC power-up and power-down tran-
sition or system noise.
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 5ns(typical) on CE# or WE#
will not initiate a write cycle.
LOGICAL INHIBIT
Writing is 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.

REV. 1.2, DEC. 09, 2005
P erfo rming a read o peratio n with A1=VIH, it will produce
a logical "1" at Q0 for the protected sector.
CHIP UNPROTECTED
The KH29L V800C T/B also features the chip unpro tected
mode, so that all sectors are unpro tected after chip un-
pro tected is completed to incorporate any changes in the
code. It is recommended to protect all sectors before
activating chip unprotected mo de.
To activate this mode, the pro gramming equipment must
force VID on control pin OE# and address pin A9. The
CE# pins must be set at VIL. Pins A6 must be set to
VIH. Refer to chip unprotected algorithm and waveform
for the chip unprotected algorithm. The unprotection
mechanism begins o n the falling edge o f the WE# pulse
and is terminated on the rising edge.
It is also possible to determine if the chip is unprotected
in the system by writing the Read Silicon ID command.
P erfo rming a read o peratio n with A1=VIH, it will produce
00H at data o utputs (Q0-Q7) f o r an unpro tected secto r .
It is noted that all sectors are unprotected after the chip
unprotected algorithm is completed.
