GENERAL DESCRIPTION
The MX29LV160C T/B is a 16-mega bit Flash memory
organized as 2M bytes of 8 bits or 1M words of 16 bits.
MXIC's Flash memories offer the most cost-effective
and reliable read/write non-volatile random access
memory. The MX29LV160C T/B is packaged in 44-pin
SOP, 48-pin TSOP and 48-ball CSP. It is designed to be
reprogrammed and erased in system or in standard
EPROM programmers.
TTL level control inputs and fixed power supply levels
during erase and programming, while maintaining maximum EPROM compatibility.
MXIC Flash technology reliably stores memory contents
even after 100,000 erase and program 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 cycling. The MX29LV160C T/B uses a 2.7V~3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
The standard MX29LV160C T/B offers access time as
fast as 55ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV160C T/B has separate chip enable
(CE#) and output enable (OE#) controls.
The highest degree of latch-up protection is achieved
with MXIC's proprietary non-epi process. Latch-up protection is proved for stresses up to 100 milliamps on
address and data pin from -1V to VCC + 1V.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29LV160C T/B uses a command register to manage
this functionality. The command register allows for 100%

MX29LV160C T/B
dard microprocessor write timings. The device will automatically pre-program and verify the entire array. Then
the device automatically times the erase pulse width,
provides the erase verification, and counts the number of
sequences. A status bit toggling between consecutive
read cycles provides feedback to the user as to the status of the erasing operation.
AUTOMATIC PROGRAMMING
The MX29LV160C T/B is byte/word programmable using
the Automatic Programming algorithm. The Automatic
Programming 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 of the MX29LV160C T/B is less than
18 sec (byte)/12 sec (word).
Register contents serve as inputs to an internal statemachine which controls the erase and programming circuitry. During write cycles, the command register internally latches address and data needed for the programming 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.
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 device automatically
times the programming pulse width, provides the program verification, and counts the number of sequences.
A status bit similar to Data# Polling and a status bit
toggling between consecutive read cycles, provide feedback to the user as to the status of the programming
operation. Refer to write operation status, table 7, for more
information on these status bits.
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29LV160C T/B
electrically erases all bits simultaneously using FowlerNordheim tunneling. The bytes are programmed by using the EPROM programming mechanism of hot electron
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 register to respond to its full command set.
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 room temperature is accomplished in
less than 25 second. The Automatic Erase algorithm
automatically programs the entire array prior to electrical
erase. The timing and verification of electrical erase are
controlled internally within the device.
AUTOMATIC SELECT
AUTOMATIC ERASE ALGORITHM
The automatic select mode provides manufacturer and
device identification, and sector protection verification,
through identifier codes output on Q7~Q0. This mode is
mainly adapted for programming equipment on the device 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. 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 select command through the command register without requiring VID,
as shown in table 5.
MXIC's Automatic Erase algorithm requires the user to
write commands to the command register using stan-
To verify whether or not sector being protected, the sector address must appear on the appropriate highest order
AUTOMATIC SECTOR ERASE
The MX29LV160C T/B is sector(s) erasable using MXIC's
Auto Sector Erase algorithm. The Automatic Sector
Erase algorithm automatically programs the specified
sector(s) prior to electrical erase. The timing and verification of electrical erase are controlled internally within
the device. An erase operation can erase one sector,
multiple sectors, or the entire device.

MX29LV160C T/B
REQUIREMENTS FOR READING ARRAY DATA
Characteristics" section contains timing specification
table and timing diagrams for write operations.
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.
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
mode, but the standby current will be larger. During Auto
Algorithm operation, 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.
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.
OUTPUT DISABLE
WRITE COMMANDS/COMMAND SEQUENCES
With the OE# input at a logic high level (VIH), output
from the devices are disabled. This will cause the output
pins to be in a high impedance state.
To program data to the device or erase sectors of
memory, the system must drive WE# and CE# to VIL,
and OE# to VIH.
An erase operation can erase one sector, multiple sectors, or the entire device. Table 1 and Table 2 indicate 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 5 defines the valid register command sequences. Writing incorrect address and
data values or 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.
RESET# OPERATION
After the system writes the "read silicon-ID" and "sector
protect verify" command sequence, the device enters
the "read silicon-ID" and "sector protect verify" mode.
The system can then read "read silicon-ID" and "sector
protect verify" 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 "read
silicon-ID" and "sector protect verify" Mode and "read
silicon-ID" and "sector protect verify" Command Sequence section for more information.
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.
ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the inter-
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.
The RESET# pin may be tied to system reset circuitry.
A system reset would that also reset the Flash memory,
enabling the system to read the boot-up firmware from
the Flash memory.
P/N:PM1186
REV. 1.2, JAN. 19, 2006

MX29LV160C T/B
nal 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 completed within a time of
tREADY (not during Embedded Algorithms). The system
can read data tRH after the RESET# pin returns to VIH.
AUTOMATIC CHIP ERASE COMMANDS
Chip erase is a six-bus cycle operation. There are two
"unlock" write cycles. These are followed by writing the
"set-up" command 80H. Two more "unlock" write cycles
are then followed by the chip erase command 10H.
The device does not require the system to entirely preprogram prior to executing the Automatic Chip Erase.
Upon executing the Automatic Chip Erase, the device
will automatically program and verify the entire memory
for an all-zero data pattern. When the device is automatically verified to contain an all-zero pattern, a selftimed chip erase and verify begin. The erase and verify
operations are completed when the data on Q7 is "1" at
which time the device returns to the Read mode. The
system is not required to provide any control or timing
during these operations.
Refer to the AC Characteristics tables for RESET# parameters and to Figure 22 for the timing diagram.
READ/RESET COMMAND
The read or reset operation is initiated by writing the read/
reset command sequence into the command register.
Microprocessor read cycles retrieve array data. The device remains enabled for reads until the command register contents are altered.
When using the Automatic Chip 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).
If program-fail or erase-fail happen, the write of F0H will
reset the device to abort the operation. A valid command must then be written to place the device in the
desired state.
If the Erase operation was unsuccessful, the data on Q5
is "1" (see Table 8), indicating the erase operation exceed internal timing limit.
SILICON-ID READ COMMAND
Flash memories are intended for use in applications where
the local CPU alters memory contents. As such, manufacturer and device codes must be accessible while the
device resides in the target system. PROM programmers typically access signature codes by raising A9 to
a high voltage (VID). However, multiplexing high voltage
onto address lines is not generally desired system design practice.
The automatic erase begins on the rising edge of the last
WE# or CE# pulse, whichever happens first in the command sequence and terminates when either the data on
Q7 is "1" at which time the device 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 MX29LV160C T/B contains a Silicon-ID-Read operation to supple traditional PROM programming methodology. The operation is initiated by writing the read
silicon ID command sequence into the command register. Following the command write, a read cycle with
A1=VIL, A0=VIL retrieves the manufacturer code of C2H/
00C2H. A read cycle with A1=VIL, A0=VIH returns the
device code of C4H/22C4H for MX29LV160CT, 49H/2249H
for MX29LV160CB.
The system must write the reset command to exit the
"Silicon-ID Read Command" code.

READING ARRAY DATA
RESET COMMAND
The device is automatically set to reading array data
after device power-up. No commands are required to retrieve data. The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
Writing the reset command to the device resets the device to reading array data. Address bits are don't care 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 reading array
data. Once erasure begins, however, the device ignores
reset commands until the operation is complete.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The system
can read array data using the standard read timings,
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 "Erase Suspend/Erase
Resume Commands" for more information on this mode.
The system must issue the reset command to re-enable the device for reading array data if Q5 goes high, or
while in the "read silicon-ID" and "sector protect verify"
mode. See the "Reset Command" section, next.
The reset command may be written between the sequence cycles in a program command sequence before
programming begins. This resets the device to reading
array data (also applies to programming in Erase Suspend 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 Automatic Select command sequence. Once in the Automatic Select mode, the reset
command must be written to return to reading array data
(also applies to Automatic Select during Erase Suspend).
If Q5 goes high during a program or erase operation, writing the reset command returns the device to reading array data (also applies during Erase Suspend).

SECTOR ERASE COMMANDS
Erase operation. When the Erase Suspend Command is
issued during the sector erase operation, the device requires a maximum 20us to suspend the sector 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. After this command has been executed, the command register will initiate erase suspend
mode. The state machine will return to read mode automatically after suspend is ready. At this time, state machine only allows the command register to respond to
Erase Resume, program data to , or read data from any
sector not selected for erasure. The system can use Q7
or Q6 and Q2 together, to determine if a sector is actively erasing or is erase-suspend.
The device does not require the system to entirely preprogram prior to executing the Automatic Sector Erase
Set-up command and Automatic Sector Erase command. Upon executing the Automatic Sector Erase command, the device will automatically 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 device 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.
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 program operation is complete, the system can once again
read array data within non-suspended sectors.
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 "unlock" 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 sector address is latched on the falling edge of 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 successive sector load cycle started by the falling edge of WE#
or CE#, whichever happens later must begin within 50us
from the rising edge of the preceding WE# or CE#, whichever happens first. Otherwise, the loading period ends
and internal auto sector erase cycle starts. (Monitor 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 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. The minimum time from Erase Resume to next Erase Suspend
is 400us. Repeatedly suspending the device more often
may have undetermined effects.
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 5 shows the address
and data requirements for the byte program command
sequence.
ERASE SUSPEND
This command only has meaning while the state machine is executing Automatic Sector Erase operation, and
therefore will only be responded during Automatic Sector
When the Embedded Program algorithm is complete, the
P/N:PM1186
REV. 1.2, JAN. 19, 2006
15
MX29LV160C T/B
device then returns to reading array data and addresses
are no longer latched. The system can determine the
status of the program operation by using
Q7, Q6, or RY/BY#. See "Write Operation Status" for
information on these status bits.
During the Automatic Erase algorithm, Data# Polling produces a "0" on Q7. When the Automatic Erase algorithm
is complete, or if the device enters the Erase Suspend
mode, Data# Polling produces a "1" on Q7. This is analogous to the complement/true datum output described 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 sectors selected for erasure to read valid status information on Q7.
Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a hardware
reset immediately terminates the programming
operation. The Byte/Word Program command sequence
should be reinitiated once the device has reset to reading array data, to ensure data integrity.
After an erase command sequence is written, if all sectors selected for erasing are protected, 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.
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 cause the
device to 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".
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 Enable
(OE#) is asserted low.
WRITE OPERATION STATUS
The device provides several bits to determine the status
of a write operation: Q2, Q3, Q5, Q6, Q7, and RY/BY#.
Table 8 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.
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 of the final WE# or CE#, whichever
happens first, 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.
Q7: Data# Polling
The Data# Polling bit, Q7, indicates to the host system
whether an Automatic 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 program or erase command sequence.
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 ready to read array data (including during the Erase
Suspend mode), or is in the standby mode.
During the Automatic Program algorithm, the device outputs on Q7 the complement of the datum programmed to
Q7. This Q7 status also applies to programming during
Erase Suspend. When the Automatic Program algorithm
is complete, the device outputs the datum programmed
to Q7. The system must provide the program address to
read valid status information on Q7. If a program address
falls within a protected sector, Data# Polling on Q7 is
active for approximately 1 us, then the device returns to
reading array data.
Table 8 shows the outputs for RY/BY# during write operation.
Q6:Toggle BIT I
Toggle Bit I on Q6 indicates whether an Automatic Program or Erase algorithm is in progress or complete, or
whether the device has entered the Erase Suspend mode.
P/N:PM1186
REV. 1.2, JAN. 19, 2006
16
MX29LV160C T/B
Toggle Bit I may be read at any address, and is valid
after the rising edge of the final WE# or CE#, whichever
happens first, in the command sequence (prior to the
program or erase operation), and during the sector timeout.
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 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 sectors and mode information. Refer to
Table 7 to compare outputs for Q2 and Q6.
During an Automatic Program or Erase algorithm operation, successive read cycles to any address cause Q6
to toggle. The system may use either OE# or CE# to
control the read cycles. When the operation is complete,
Q6 stops toggling.
Reading Toggle Bits Q6/ Q2
After an erase command sequence is written, if all sectors 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.
Whenever the system initially begins reading toggle bit
status, it must read Q7-Q0 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 Q7-Q0 on the following read cycle.
The system can use Q6 and Q2 together to determine
whether a sector is actively erasing or is erase suspended. 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-suspended. Alternatively, the system can use Q7.
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 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 operation. If it is still toggling, the device did not complete the
operation successfully, and the system must write the
reset command to return to reading array data.
If a program address falls within a protected sector, Q6
toggles for approximately 2 us after the program command 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 algorithm
is complete.
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 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.
Table 8 shows the outputs for Toggle Bit I on Q6.
Q2:Toggle Bit II
The "Toggle Bit II" on Q2, when used with Q6, indicates
whether a particular 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 of the final WE# or CE#, whichever
happens first, in the command sequence.
Q5 : Exceeded Timing Limits
Q5 will indicate if the program or erase time has exceeded
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 suc-
Q2 toggles when the system reads at addresses within
those sectors that have been selected for erasure. (The

operation, it specifies that the entire chip is bad or combination of sectors are bad.
If this time-out condition occurs during the byte/word programming operation, it specifies that the entire sector
containing that byte/word is bad and this sector may not
be reused, (other sectors are still functional and can be
reused).
If this time-out condition occurs during sector erase operation, it specifies that a particular sector is bad and it
may not be reused. However, other sectors are still functional and may be used for the program or erase operation. The device must be reset to use other sectors.
Write the Reset command sequence to the device, and
then execute program or erase command sequence. This
allows the system to continue to use the other active
sectors in the device.
The time-out condition will not appear if a user tries to
program a non blank location without erasing. Please note
that this is not a device failure condition since the device
was incorrectly used.

MX29LV160C T/B
POWER SUPPLY DECOUPLING
Q3
Sector Erase Timer
In order to reduce power switching effect, each device
should have a 0.1uF ceramic capacitor connected between its VCC and GND.
After the completion of the initial sector erase command
sequence, the sector erase time-out will begin. Q3 will
remain low until the time-out is complete. Data# Polling
and Toggle Bit are valid after the initial sector erase command sequence.
POWER-UP SEQUENCE
The MX29LV160C T/B powers up in the Read only mode.
In addition, the memory contents may only be altered
after successful completion of the predefined command
sequences.
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
operation is completed as indicated by Data# Polling or
Toggle Bit. If Q3 is low ("0"), the device will accept additional sector erase commands. To insure the command
has been accepted, the system software should check
the status of Q3 prior to and following each subsequent
sector erase command. If Q3 were high on the second
status check, the command may not have been accepted.
TEMPORARY SECTOR UNPROTECT
This feature allows temporary unprotection of previously
protected sector to change data in-system. The Temporary Sector Unprotect 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.
DATA PROTECTION
The MX29LV160C 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 resets the state machine in the Read mode. In addition,
with its control register architecture, alteration of the
memory contents only occurs after successful completion of specific command sequences. The device also
incorporates several features to prevent inadvertent write
cycles resulting from VCC power-up and power-down transition or system noise.
SECTOR PROTECTION
The MX29LV160C T/B features hardware sector protection. 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). Programming of the protection circuitry begins on the falling edge
of the WE# pulse and is terminated on the rising edge.
Please refer to sector protect algorithm and waveform.
To verify programming of the protection circuitry, the programming equipment must force VID on 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 device output Q0 for a protected sector. Otherwise the device will produce 00H for the unprotected sector. In this mode, the addresses, except for A1, are don't
care. Address locations with A1 = VIL are reserved to
read manufacturer and device codes. (Read Silicon ID)
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 5ns (typical) on OE#, 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.
It is also possible to determine if the sector is protected
in the system by writing a Read Silicon ID command.
Performing a read operation with A1=VIH, it will produce
P/N:PM1186
REV. 1.2, JAN. 19, 2006
19
MX29LV160C T/B
a logical "1" at Q0 for the protected sector.
The system must write the reset command to exit the
"Silicon-ID Read Command" code.
CHIP UNPROTECT
The MX29LV160C T/B also features the chip unprotect
mode, so that all sectors are unprotected after chip
unprotect is completed to incorporate any changes in the
code. It is recommended to protect all sectors before
activating chip unprotect mode.
To activate this mode, the programming 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 unprotect algorithm and waveform for the
chip unprotect algorithm. The unprotection mechanism
begins on the falling edge of 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.
Performing a read operation with A1=VIH, it will produce
00H at data outputs(Q0-Q7) for an unprotected sector.
It is noted that all sectors are unprotected after the chip
unprotect algorithm is completed.
