MX26L3220
All data are latched on the rising edge of WE or CE,
whichever happens later.
AUTOMATIC PROGRAMMING
The MX26L3220 is word programmable using the Auto-
matic Programming algorithm. The Automatic Program-
ming algorithm makes the external system do not need
to have time out sequence nor to verify the data pro-
grammed. The typical chip programming time at room
temperature of the MX26L3220 is less than 90 seconds.
MXIC's Flash technology combines years of EPROM
experience to produce the highest levels of quality, relia-
bility, and cost effectiveness. The MX26L3220 electri-
cally erases all bits simultaneously using Fowler-Nord-
heim tunneling. The bytes are programmed by using the
EPROM programming mechanism of hot electron injec-
tion.
AUTOMATIC PROGRAMMING ALGORITHM
MXIC's Automatic Programming algorithm require the user
to only write program set-up commands (including 2 un-
lock write cycle and A0H) and a program command (pro-
gram data and address). The device automatically times
the programming pulse width, provides the program veri-
fication, and counts the number of sequences. A status
bit similar to DATA polling and a status bit toggling be-
tween consecutive read cycles, provide feedback to the
user as to the status of the programming operation.
During a program cycle, the state-machine will control
the program sequences and command register will not
respond to any command set. After the state machine
has completed its task, it will allow the command regis-
ter 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 45 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 ERASE ALGORITHM
MXIC's Automatic Erase algorithm requires the user to
write commands to the command register using stand-
ard microprocessor write timings. The device will auto-
matically 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 consecu-
tive read cycles provides feedback to the user as to the
status of the programming operation.
Register contents serve as inputs to an internal state-
machine which controls the erase and programming cir-
cuitry. During write cycles, the command register inter-
nally latches address and data needed for the program-
ming and erase operations. All address are latched on
the falling edge of WE or CE, whichever happens later.

MX26L3220
REQUIREMENTS FOR READING ARRAY
DATA
STANDBY MODE
MX26L3220 can be set into Standby mode with two dif-
ferent approaches. One is using both CE and RESET
pins and the other one is using RESET pin only.
To read array data from the outputs, the system must
drive the CE and OE pins toVIL.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.
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 50uA (typ.). If both of the CE and RESET are held
atVIH, but not within the range ofVCC ± 0.3V, the device
will still be in the standby mode, but the standby currect
will be larger. During Auto Algorithm operation, Vcc ac-
tive current (Icc2) is required even CE = "H" until the
operation is complated.The device can be read with stan-
dard access time (tCE) from either of these standby
modes.
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 contect
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.
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 50uA
(typ.). Once the RESET pin is taken high,the device is
back to active without recovery delay.
WRITE COMMANDS/COMMAND
SEQUENCES
To program data to the device the system must drive
WE and CE to VIL, and OE to VIH.
In the standby mode the outputs are in the high imped-
ance state, independent of the OE input.
An erase operation can erase the entire device. The
"Writing specific address and data commands or
sequences into the command register initiates device
operations. Table 1 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 the
entire chip.
MX26L3220 is capable to provide the Automatic Standby
Mode to restrain power consumption during read-out of
data.This mode can be used effectively with an applica-
tion requested low power consumption such as handy
terminals.
To active this mode, MX26L3220 automatically switch
themselves to low power mode when MX26L3220 ad-
dresses 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 typi-
cally 50uA (CMOS level).
After the system writes the autoselect command
sequence, the device enters the autoselect mode. The
system can then read autoselect codes from the internal
reqister (which is separate from the memory array) on
Q15-Q0. Standard read cycle timings apply in this mode.
Refer to the Autoselect Mode and Autoselect Command
Sequence section for more information.
OUTPUT DISABLE
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.
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
Table 3
VCC / VI/O Voltage Range
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 pluse. The
device also resets the internal state machine to reading
array data.The operation that was interrupted should be
reinitated once the device is ready to accept another
command sequence, to ensure data integrity

Notes: Typical values measured atVCC=2.7V to 3.6V,

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.
DATA PROTECTION
The MX26L3220 is designed to offer protection against
accidental erasure or programming caused by spurious
system level signals that may exist during power transi-
tion. 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 spe-
cific command sequences. The device also incorporates
several features to prevent inadvertent write cycles re-
sulting fromVCC power-up and power-down transition or
system noise.
The RESET pin may be tied to system reset circuitry. A
system reset would that also reset the MTP EPROM.
Refer to the AC Characteristics tables for RESET
parameters and to Figure 14 for the timing diagram.
SILICON ID READ OPERATION
MTP EPROM are intended for use in applications where
the local CPU alters memory contents. As such, manu-
facturer and device codes must be accessible while the
device resides in the target system. EPROM program-
mers typically access signature codes by raising A9 to
a high voltage. However, multiplexing high voltage onto
address lines is not generally desired system design prac-
tice.
SECURED SILICON SECTOR
The MX26L3220 features a Flash memory region where
the system may access through a command sequence
to create a permant part identification as so called Elec-
tronic Serial Number (ESN) in the device. Once this re-
gion is programmed, any further modification on the re-
gion is impossible. The secured silicon sector is a 512
words in length, and uses a Secured Silicon Sector Indi-
cator Bit (Q7) to indicate whether or not the Secured
Silicon Sector is locked when shipped from the factory.
This bit is permanently set at the factory and cannot be
changed, which prevent duplication of a factory locked
part.This ensures the security of the ESN once the prod-
uct is shipped to the field.
MX26L3220 provides hardware method to access the
silicon ID read operation.Which method requiresVID on
A9 pin, VIL on CE, OE, A6, and A1 pins. Which apply
VIL on A0 pin, the device will output MXIC's manufac-
ture code of C2H.Which applyVIH on A0 pin, the device
will output MX26L3220 device code of 22FDH.
The MX26L3220 offers the device with Secured Silicon
Sector either factory locked or custor lockable.The fac-
tory-locked version is always protected when shipped
from the factory , and has the Secured Silicon Sector
Indicator Bit permanently set to a "1". The customer-
lockable version is shipped with the Secured Silicon
Sector unprotected, allowing customer to utilize that sec-
tor in any form they prefer.The customer-lockable ver-
VI/O PIN OPERATION
MX26L3220 is capable to provide the I/O prower supply
(VI/O) pin to control Input/Output voltage levels of the
device.The data outputs and voltage tolerated at its data
input is determined by the voltage on the VI/O pin.This
device is allows to operate in 1.8V or 3V system as re-
quired.

MX26L3220
sion has the secured sector Indicator Bit permanently
set to a "0". Therefore, the Secured Silicon Sector Indi-
cator Bit permanently set to a "0".Therefore, the Second
Silicon Sector Indicator Bit prevents customer, lockable
device from being used to replace devices that are fac-
tory locked.
FACTORY LOCKED:Secured Silicon Sector
Programmed and Protected At the Factory
In device with an ESN, the Secured Silicon Sector is
protected when the device is shipped from the factory.
The Secured Silicon Sector cannot be modified in any
way.A factory locked device has an 8-word random ESN
at address 000000h-000007h.
The system access the Secured Silicon Sector through
a command sequence (refer to "Enter Secured Silicon/
Exit Secured Silicon Sector command Sequence). After
the system has written the Enter Secured Silicon Sector
command sequence, it may read the Secured Silicon
Sector by using the address normally occupied by the
address 000000h-0001FFh.This mode of operation con-
tinues until the system issues the Exit Secured Silicon
Sector command sequence, or until power is removed
from the device. On power-up, or following a hardware
reset, the device reverts to sending command to ad-
dress 000000h-0001FFFh.
CUSTOMER LOCKABLE:Secured Silicon
Sector NOT Programmed or Protected At the
Factory
As an alternative to the factory-locked version, the device
may be ordered such that the customer may program
and protect the 512-word Secured Silicon Sector.
Programming and protecting the Secured Silicon Sector
must be used with caution since, once protected, there
is no procedure available for unprotecting the Secured
Silicon Sector area and none of the bits in the Secured
Silicon Sector memory space can be modified in any
way.
LOW VCC WRITE INHIBIT
When VCC is less than VLKO the device does not ac-
cept any write cycles. This protects dataduring 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 thanVLKO. The system must provide the proper
signals to the control pins to prevent unintentional write
whenVCC is greater thanVLKO.
The Secured Silicon Sector area can be protected using
the following procedures:
Write the three-cycle Enter Secured Silicon Sector Region
command sequence. This allows in-system protection
of the Secured Silicon Sector without raising any device
pin to a high voltage. Note that method is only applicable
to the Secured Silicon Sector.
WRITE PULSE "GLITCH" PROTECTION
Once the Secured Silicon Sector is programmed, locked
and verified, the system must write the Exit Secured
Silicon Sector Region command sequence to return to
reading and writing the remainder of the array.
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.
POWER-UP SEQUENCE
The MX26L3220 powers up in the Read only mode. In
addition, the memory contents may only be altered after
successful completion of the predefined command se-
quences.

ID READ mode, and the system may read at any address
any number of times, without init iating another command
sequence. A read cycle at address XX00h retrieves the
manufacturer code. A read cycle at address XX01h re-
turns the device code.
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data.The device is also ready to read array data
after completing an Automatic Program or Automatic
Erase algorithm.
The system must write the reset command to exit the
autoselect mode and return to reading array data.
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.
WORD PROGRAM COMMAND SEQUENCE
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 4 shows the address
and data requirements for the byte program command
sequence.
RESET COMMAND
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 se-
quence 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.
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. See
"Write Operation Status" for information on these status
bits.
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.Once programming begins,however, the device
ignores reset commands until the operation is complete.
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 Word Program command sequence should
be reinitiated once the device has reset to reading array
data, to ensure data integrity.
The reset command may be written between the se-
quence cycles in an SILICON ID READ command
sequence. Once in the SILICON ID READ mode, the
reset command must be written to return to reading array
data.
Programming is allowed in any sequence. A bit cannot
be programmed from a "0" back to a "1". 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".
If Q5 goes high during a program or erase operation,
writing the reset command returns the device to reading
array data.
SILICON ID READ COMMAND SEQUENCE
The SILICON ID READ command sequence allows the
host system to access the manufacturer and devices
codes, and determine whether or not. Table 4 shows the
address and data requirements. This method is an
alternative to that shown in Table 1, which is intended for
EPROM programmers and requires VID on address bit
A9.
ACCELERATED PROGRAM OPERATIONS
The device offers accelerated program operations through
the ACC pin. When the system asserts VHH on the ACC
pin, the device automatically bypass the two "Unlock"
write cycle. The device uses the higher voltage on the
ACC pin to accelerate the operation. Note that the ACC
pin must not be atVHH any operation other than accelerated
programming, or device damage may result.
The SILICON ID READ command sequence is initiated
by writing two unlock cycles, followed by the SILICON
ID READ command.The device then enters the SILICON

is not required to provide any controls or timings during
these operations. Table 4 shows the address and data
requirements for the chip erase command sequence.
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.
Any commands written to the chip during the Automatic
Erase algorithm are ignored. Note that a hardware reset
during the chip erase operation immediately terminates
the operation.The Chip Erase command sequence should
be reinitiated once the device has returned to reading
array data, to ensure data integrity.
The MX26L3220 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. Follow-
ing the command write, a read cycle with A6=VIL,
A1=VIL, A0=VIL retrieves the manufacturer code of C2H.
A read cycle with A6=VIL, A1=VIL, A0=VIH returns the
device code of 22FDH for MX26L3220.
The system can determine the status of the erase op-
eration by using Q7, Q6. See "Write Operation Status"
for information on these status bits.When the Automatic
Erase algorithm is complete, the device returns to read-
ing array data and addresses are no longer latched.
AUTOMATIC CHIP ERASE COMMAND
Figure 5 illustrates the algorithm for the erase opera-
tion.See the Erase/Program Operations tables in "AC
Characteristics" for parameters, and to Figure 4 for tim-
ing diagrams.
The device does not require the system to preprogram
prior to erase.The Automatic Erase algorithm automati-
cally preprograms and verifies the entire memory for an
all zero data pattern prior to electrical erase.The system

sections describe the functions of these bits. Q7, and
Q6 each offer a method for determining whether a pro-
gram or erase operation is complete or in progress.These
three bits are discussed first.
WRITE OPERSTION STATUS

tus of a write operation: Q5, Q6, Q7.The following sub-

If this time-out condition occurs during chip erase opera-
tion, it specifies that Device is bad and it may not be
reused. Write the Reset command sequence to the de-
vice, and then execute program or erase command se-
quence. This allows the system to continue to use the
other active sectors in the device.
Q7: Data Polling
The Data Polling bit, Q7, indicates to the host system
whether an Automatic Algorithm is in progress or com-
pleted. Data Polling is valid after the rising edge of the
final WE pulse in the program or erase command se-
quence.
If this time-out condition occurs during the chip erase
operation, it specifies that the entire chip is bad.
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 programming dur-
ing Er ase Suspend.When the Automatic Program algo-
rithm is complete, the device outputs the datum pro-
grammed to Q7.The system must provide the program
address to read valid status information on Q7.
If this time-out condition occurs during the word program-
ming operation, the word is bad and maynot be reused,
(other word are still functional and can be reused).
During the Automatic Erase algorithm, Data Polling pro-
duces a "0" on Q7.When the Automatic Erase algorithm
is complete. Data Polling produces a "1" on 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 to "1" prior to this, the de-
vice outputs the "complement,” or "0".”
Q6:Toggle BIT I
Toggle Bit I on Q6 indicates whether an Automatic Pro-
gram or Erase algorithm is in progress or complete.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 pulse in the command sequence(prior to the pro-
gram or erase operation).
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 con-
trol the read cycles.When the operation is complete, Q6
stops toggling.
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 suc-
cessfully completed. Data Polling andToggle Bit are the
only operating functions of the device under this condi-
tion.
