GENERAL DESCRIPTION
The MX29LV320C T/B is a 32-mega bit Flash memory
organized as 4M bytes of 8 bits and 2M words of 16 bits.
MXIC's Flash memories offer the most cost-effective and
reliable read/write non-volatile random access memory.
The MX29LV320C T/B is packaged in 48-pin TSOP and
48-ball CSP. It is designed to be reprogrammed and
erased in system or in standard EPROM programmers.
MXIC's Flash memories augment EPROM functionality
with in-circuit electrical erasure and programming. The
MX29LV320C T/B uses a command register to manage
this functionality.
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 program
mechanisms. In addition, the combination of advanced
tunnel oxide processing and low internal electric fields
for erase and programming operations produces reliable
The standard MX29LV320C T/B offers access time as
fast as 70ns, allowing operation of high-speed microprocessors without wait states. To eliminate bus contention, the MX29LV320C T/B has separate chip enable
(CE#) and output enable (OE#) controls.

cycling. The MX29LV320C T/B uses a 2.7V to 3.6V VCC
supply to perform the High Reliability Erase and auto
Program/Erase algorithms.
automatically programs the specified sector(s) prior to
electrical erase. The timing and verification of electrical erase are controlled internally within the device.
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 milliamperes on address
and data pin from -1V to VCC + 1V.
AUTOMATIC ERASE ALGORITHM
MXIC's Automatic Erase algorithm requires the user to
write commands to the command register using standard 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 programming operation.
AUTOMATIC PROGRAMMING
The MX29LV320C 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 MX29LV320C T/B is less than
36 seconds.
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# .
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm require 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.
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, reliability, and cost effectiveness. The MX29LV320C T/B electrically erases all bits simultaneously using Fowler-Nordheim tunneling. The bytes/words 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 50 ms erase pulses
according to MXIC's Automatic Chip Erase algorithm.
Typical erasure at room temperature is accomplished in
less than 35 seconds. 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 SECTOR ERASE
The MX29LV320C T/B is sector(s) erasable using
MXIC's Auto Sector Erase algorithm. Sector erase
modes allow sectors of the array to be erased in one
erase cycle. The Automatic Sector Erase algorithm

MX29LV320C T/B
REQUIREMENTS FOR READING ARRAY DATA
ACCELERATED PROGRAM OPERATION
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 device offers accelerated program operations through
the ACC function. If the system asserts VHH on WP#/
ACC pin, the device will provide the fast programming
time to user. This function is primarily intended to allow
faster manufacturing throughput during production. 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.
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.
STANDBY MODE
MX29LV320C T/B can be set into Standby mode with
two different approaches. One is using both CE# and
RESET# pins and the other one is using RESET pin only.
WRITE COMMANDS/COMMAND SEQUENCES
When using both pins of CE# and RESET#, a CMOS
Standby mode is achieved with both pins held at VCC ±
0.3V. Under this condition, the current consumed is less
than 0.2uA (typ.). If both of the 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.
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 indicates the address
space that each sector occupies. A "sector address"
consists of the address bits required to uniquely select a
sector. Writing specific address and data commands or
sequences into the command register initiates device
operations. Table 3 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.
When using only RESET#, a CMOS standby mode is
achieved with RESET# input held at Vss ± 0.3V, Under
this condition the current is consumed less than 1uA
(typ.). Once the RESET# pin is taken high, the device is
back to active without recovery delay.
In the standby mode the outputs are in the high impedance state, independent of the OE# input.
After the system writes the Automatic Select command
sequence, the device enters the Automatic Select mode.
The system can then read Automatic Select 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 Automatic Select Mode and Automatic Select Command Sequence section for more information.
MX29LV320C T/B is capable to provide the Automatic
Standby Mode to restrain power consumption during readout of data. This mode can be used effectively with an
application requested low power consumption such as
handy terminals.
To active this mode, MX29LV320C T/B automatically
switch themselves to low power mode when
MX29LV320C T/B addresses remain stable during access time of tACC+30ns. It is not necessary to control
CE#, WE#, and OE# on the mode. Under the mode, the
current consumed is typically 0.2uA (CMOS level).
ICC2 in the DC Characteristics table represents the active current specification for the write mode. The "AC
Characteristics" section contains timing specification table
and timing diagrams for write operations.

MX29LV320C T/B
OUTPUT DISABLE
The primary method requires VID on the RESET# only.
This method can be implemented either in-system or via
programming equipment. This method uses standard microprocessor bus cycle timing. Refer to Figure 13 for timing diagram and Figure 14 illustrates the algorithm for the
sector group protection operation.
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.
RESET# OPERATION
The alternate method intended only for programming
equipment, must force VID on address pin A9 and control pin OE#, (suggest VID = 12V) A6 = VIL and CE# =
VIL(see Table 2). Programming of the protection circuitry
begins on the falling edge of the WE# pulse and is terminated on the rising edge. Contact MXIC for details.
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
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=1,
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)
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.
It is also possible to determine if the group is protected
in the system by writing a Read Silicon ID command.
Performing a read operation with A1=VIH, it will produce
a logical "1" at Q0 for the protected sector.
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 firm-ware from
the Flash memory.
CHIP UNPROTECT OPERATION
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the internal reset operation is complete, which requires a time of
tREADY (during Embedded Algorithms). The system can
thus monitor RY/BY# to determine whether the reset operation is complete. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is
"1"), the reset operation is completed within a time of
tREADY (not during Embedded Algorithms). The system
can read data tRH after the RESET# pin returns to VIH.
The MX29LV320C 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.
The primary method requires VID on the RESET# only.
This method can be implemented either in-system or via
programming equipment. This method uses standard
microprocessor bus cycle timing. Refer to Figure 13 for
timing diagram and Figure 14 illustrates the algorithm for
the sector group protection operation.
Refer to the AC Characteristics tables for RESET# parameters and to Figure 14 for the timing diagram.
The alternate method intended only for programming
equipment, must force VID on address pin A9 and control pin OE#, (suggest VID = 12V) A6 = VIL and CE# =
VIL(see Table 2). Programming of the protection circuitry
begins on the falling edge of the WE# pulse and is terminated on the rising edge. Contact MXIC for details.
SECTOR GROUP PROTECT OPERATION
The MX29LV320C T/B features hardware sector group
protection. This feature will disable both program and
erase operations for these sector group protected. Sector protection can be implemented via two methods.
P/N:PM1188
REV. 1.0, AUG. 02, 2005
12
MX29LV320C T/B
facturer 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. However, multiplexing high voltage onto
address lines is not generally desired system design practice.
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.
MX29LV320C T/B provides hardware method to access
the Automatic Select operation. This method requires VID
on A9 pin, VIL on CE#, OE#, A6, and A1 pins. When
applying VIL on A0 pin, the device will output MXIC's
manufacture code of C2H. When applying VIH on A0 pin,
the device will output MX29LV320C T/B device code of
22A7h and 22A8h.
TEMPORARY SECTOR GROUP UNPROTECT OPERATION
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.
VERIFY SECTOR GROUP PROTECT STATUS OPERATION
MX29LV320C T/B provides hardware method for sector
group protect status verify. This method requires VID on
A9 pin, VIH on WE# and A1 pins, VIL on CE#, OE#, A6,
and A0 pins, and sector address on A12 to A20 pins.
When the identified sector is protected, the device will
output 01H. When the identified sector is not protect, the
device will output 00H.
WRITE PROTECT (WP#)
The write protect function provides a hardware method to
protect boot sectors without using VID.
If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the two "outermost" 8 Kbyte boot sectors independently of whether
those sectors were protected or unprotected using the
method described in Sector/Sector Group Protection and
Chip Unprotection". The two outermost 8 Kbyte boot sectors are the two sectors containing the lowest addresses
in a bottom-boot-configured device, or the two sectors
containing the highest addresses in a top-boot-configured
device.
SECURITY SECTOR FLASH MEMORY REGION
The Security Sector (Security Sector) feature provides a
Flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The
Security Sector is 64 Kbytes (32 Kwords) in length, and
uses a Security Sector Indicator Bit (Q7) to indicate
whether or not the Security Sector is locked when shipped
from the factory. This bit is per-manently 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.
If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the two outermost 8K Byte boot
sectors were last set to be protected or unprotected. That
is, sector protection or unprotection for these two sectors
depends on whether they were last protected or unprotected using the method described in "Sector/Sector Group
Protection and Chip Unprotection".
MXIC offers the device with the Security Sector either
factory locked or customer lockable. The factory-locked
version is always protected when shipped from the factory, and has the Security on Silicon Sector (Security
Sector) Indicator Bit permanently set to a "1". The customer-lockable version is shipped with the unprotected,
allowing customers to utilize the that sector in any manner they choose. The customer-lockable version has the
Security on Silicon Sector (Security Sector) Indicator Bit
permanently set to a "0". Thus, the Security Sector Indicator Bit prevents customer-lockable devices from being
Note that the WP#/ACC pin must not be left floating or
unconnected; inconsistent behavior of the device may
result.

the Security Sector.
The system accesses the Security Sector through a command sequence (see "Enter Security Sector/Exit Security Sector Command Sequence"). After the system has
written the Enter Security Sector command se-quence,
it may read the Security Sector by using the ad-dresses
normally occupied by the boot sectors. This mode of operation continues until the system issues the Exit Security 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 the
boot sectors.
Write the three-cycle Enter Security Region command
sequence, and then use the alternate method of sector
protection described in the "Sector/Sector Block Protection and Unprotection section.
Once the Security Sector is locked and verified, the system must write the Exit Security Sector Region command sequence to return to reading and writing the remainder of the array.
The Security Sector protection must be used with caution since, once protected, there is no procedure available for unprotecting the Security Sector area and none
of the bits in the Security Sector memory space can be
modified in any way.
Factory Locked: Security Sector Programmed and
Protected at the Factory
In a factory locked device, the Security Sector is protected when the device is shipped from the factory. The
Security Sector cannot be modified in any way. The device is available preprogrammed with one of the following:
DATA PROTECTION
The MX29LV320C 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.
A random, secure ESN only.
In devices that have an ESN, a Bottom Boot device will
have the 16-byte (8-word) ESN in the lowest addressable memory area starting at 00000h and ending at
0000Fh (00007h). In the Top Boot device the starting
address of the ESN will be at the bottom of the lowest 8
Kbyte (4 Kword) boot sector starting at 3F0000h
(1F8000h) and ending at 3F000Fh (1F8007h).
LOW VCC WRITE INHIBIT
Customer Lockable: Security Sector NOT Programmed or Protected at the Factory
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. Subsequent writes are ignored until VCC
is greater than VLKO. The system must provide the proper
signals to the control pins to prevent unintentional write
when VCC is greater than VLKO.
If the security feature is not required, the Security Sector can be treated as an additional Flash memory space,
expanding the size of the available Flash array by 64
Kbytes (32 Kwords). The Security Sector can be read,
programmed, and erased as often as required. The Security Sector area can be protected using one of the
following procedures:
Write the three-cycle Enter Security Region command
sequence, and then follow the in-system sector group
protect algorithm as shown in Figure 14, except that
RESET# may be at either VIH or VID. This allows in-system protection of the without raising any device pin to a
high voltage. Note that this method is only applicable to
WRITE PULSE "GLITCH" PROTECTION
Noise pulses of less than 5ns (typical) on OE#, CE# or
WE# will not initiate a write cycle.

MX29LV320C T/B
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.
POWER-UP SEQUENCE
The MX29LV320C 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.
POWER-UP WRITE INHIBIT
If WE#=CE#=VIL and OE#=VIH during power up, the
device does not accept commands on the rising edge of
WE#. The internal state machine is automatically reset
to the read mode on power-up.
POWER SUPPLY DECOUPLING
In order to reduce power switching effect, each device
should have a 0.1uF ceramic capacitor connected between its VCC and GND.
SOFTWARE COMMAND DEFINITIONS
Device operations are selected by writing specific address and data sequences into the command register.
Writing incorrect address and data values or writing them
in the improper sequence will reset the device to the
read mode. Table 3 defines the valid register command
sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the
Sector Erase operation is in progress. Either of the two
reset command sequences will reset the device (when
applicable).
All addresses are latched on the falling edge of WE# or
CE#, whichever happens later. All data are latched on
rising edge of WE# or CE#, whichever happens first.

READING ARRAY DATA
AUTOMATIC SELECT COMMAND SEQUENCE
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.
The Automatic Select command sequence allows the host
system to access the manufacturer and device codes,
and determine whether or not a sector is pro-tected. Table
2 shows the address and data requirements.
This method is an alternative to that shown in Table 3,
which is intended for EPROM programmers and requires
VID on address bit A9.
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 erasesuspended 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
during an active program or erase operation, or while in
the Automatic Select mode. See the "Reset Command"
section, next.
The Automatic Select command sequence is initiated
by writ-ing two unlock cycles, followed by the Automatic
Select command. The device then enters the Automatic
Select mode, and the system may read at any address
any number of times, without initiating another command
sequence. A read cycle at address XX00h retrieves the
manufacturer code. A read cycle at address XX01h in
word mode (or xx02h in byte mode) returns the device
code. A read cycle containing a sector address (SA) and
the address 02h on A7-A0 in word mode (or the address
04h on A6-A-1 in byte mode) returns 01h if that sector is
protected, or 00h if it is unprotected. Refer to Table 1 for
valid sector addresses.
RESET COMMAND
The system must write the reset command to exit the
Automatic Select mode and return to reading array data.
Writing the reset command to the device resets the device to reading array data. Address bits are don't care for
this command.
ENTER SECURITY SECTOR & EXIT SECURITY SECTOR COMMAND SEQUENCE
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.
The Security Sector provides a secured area which contains a random, sixteen-byte electronic serial
number.(ESN)
The system can access the Security Sector area by issuing the three-cycle "Enter Security Sector command
sequence. The device continues to access the security
section area until the system issues the four-cycle Exit
Security Sector command sequence. The Exit Security
Sector command sequence returns the device to normal
operation.
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).
BYTE/WORD PROGRAM COMMAND SEQUENCE
The device programs one byte/word 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
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).

command sequence.
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 Embedded Program algorithm is complete, the
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.
SETUP AUTOMATIC CHIP/SECTOR ERASE
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, or
the sector erase command 30H.
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.
The MX29LV320C T/B contains a Silicon-ID-Read operation to supplement 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.
A read cycle with A1=VIL, A0=VIH returns the device
code of A7H/A8H for MX29LV320C T/B.
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

The device does not require the system to preprogram
prior to erase. The Automatic 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 3 shows the address and data
requirements for the chip erase command sequence.
The system can determine the status of the erase operation by using Q7, Q6, Q2, or RY/BY#. See "Write Operation Status" for information on these status bits. When
the Automatic Erase algorithm is complete, the device
returns to reading array data and addresses are no longer
latched.
Any commands written to the chip during the Automatic
Erase algorithm are ignored. Note that a hard-ware reset
during the chip erase operation immediately terminates
the operation. The Chip Erase command sequence should

and therefore will only be responded during Automatic
Sector 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
the 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-suspended.
SECTOR ERASE COMMANDS
The device does not require the system to entirely
pre-program prior to executing the Automatic Set-up
Sector Erase 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 allzero 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 the data on Q7 is "1" and 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 blocks.
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 timeout 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.
ERASE SUSPEND
This command only has meaning while the state machine is executing Automatic Sector Erase operation,

MX29LV320C T/B
Q7: Data# Polling
happens first pulse in the command sequence (prior to
the program or erase operation), and during the sector
time-out.
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.
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.
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.
After an erase command sequence is written, if all sectors selected for erasing are protected, Q6 toggles for
100us 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 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.
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 out-put 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.
If a program address falls within a protected sector, Q6
toggles for approximately 2us after the program command sequence is written, then returns to reading array
data.
After an erase command sequence is written, if all sectors selected for erasing are protected, 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.
Q6 also toggles during the erase-suspend-program mode,
and stops toggling once the Automatic Program algorithm is complete.
Table 5 shows the outputs for Toggle Bit I on Q6.
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.
Q2:Toggle Bit II
Q6:Toggle BIT I
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 pulse in the command sequence.
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.
Toggle Bit I may be read at any address, and is valid
after the rising edge of the final WE# or CE#, whichever
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 compari-

MX29LV320C T/B
son, 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
5 to compare outputs for Q2 and Q6.
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.
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 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.
If this time-out condition occurs during the chip erase
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 maynot
be reused, (other sectors are still functional and can be
reused).
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.
The time-out condition may also appear if a user tries to
program a non blank location without erasing. In this
case the device locks out and never completes the Automatic Algorithm operation. Hence, the system never
reads a valid data on Q7 bit and Q6 never stops toggling.
Once the Device has exceeded timing limits, the Q5 bit
will indicate a "1". Please note that this is not a device
failure condition since the device was incorrectly used.
The Q5 failure condition may appear if the system tries
to program a "1" to a location that is 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 operation has exceeded the
timing limits, Q5 produces a "1".
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.
Q3:Sector Erase Timer
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.
Q5:Program/Erase Timing
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 successfully completed. Data# Polling and Toggle Bit are
the only operating functions of the device under this condition.
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
P/N:PM1188

MX29LV320C T/B
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.
If the time between additional erase commands from the
system can be less than 50us, the system need not to
monitor Q3.
RY/BY#:READY/BUSY# OUTPUT
The RY/BY# is a dedicated, open-drain output pin that
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 ready to read array data (includ-ing during the Erase
Suspend mode), or is in the standby mode.
QUERY COMMAND AND COMMON FLASH INTERFACE (CFI) MODE
MX29LV320C T/B is capable of operating in the CFI mode.
This mode all the host system to determine the manufacturer of the device such as operating parameters and
configuration. Two commands are required in CFI mode.
Query command of CFI mode is placed first, then the
Reset command exits CFI mode. These are described in
Table 3.
The single cycle Query command is valid only when the
device is in the Read mode, including Erase Suspend,
Standby mode, and Automatic Select mode; however, it
is ignored otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, or Automatic Select mode. The command is valid only when the device is
in the CFI mode.
