uses a command register to manage this functionality.
The MXIC's MX26F640J3 series eLiteFlashTM memory
use the most advance 2 bits/cell Nbit technology, double
the storage capacity of memory cell. The device provide
the high density eLiteFlashTM memory memory solution
with reliable performance and most cost-effective.
The MXIC's Nbit technology reliably stores memory contents even after the specific erase and program cycles.
The MXIC cell is designed to optimize the erase and
program mechanisms by utilizing the dielectric's character to trap or release charges from ONO layer.
The device organized as by 8 bits or by 16 bits of output
bus. The device is packaged in 56-Lead TSOP and 64ball CSP. It is designed to be reprogrammed and erased
in system or in standard EPROM programmers.
The device uses a 3.0V to 3.6V VCC supply to perform
the High Reliability Erase and auto Program/Erase algorithms.
The device offers fast access time and allowing operation of high-speed microprocessors without wait states.
To eliminate bus contention, the device has separate chip
enable (CE0, CE1, CE2) and output enable (OE) controls. The device augment EPROM functionality with in-
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.

FUNCTION
STANDBY
The device includes on-chip program/erase control circuitry. The Write State Machine (WSM) controls block
erase and byte/word/page program operations. Operational modes are selected by the commands written to
the Command User Interface (CUI). The Status Register
indicates the status of the WSM and when the WSM
successfully completes the desired program or block
erase operation.
When CE0, CE1 and CE2 disable the device (see table1)
and place it in standby mode. The power consumption of
this device is reduced. Data input/output are in a highimpedance(High-Z) state. If the memory is deselected
during block erase, program or lock-bit configuration, the
internal control circuits remain active and the device consume normal active power until the operation completes.
POWER-DOWN
READ
When RESET pin is at VIL the device is in the powerdown mode and its power consumption is substantially
low around 25uA. During read modes, the memory is
deselected and the data input/output are in a highimpedance(High-Z) state. To return from power down
mode requires RESET pin at VIH. After return from
powerdown, the CUI is reset to Read Array , and the
Status Register is set to value 80H.
The device has three read modes, which accesses to
the memory array, the Device Identifier or the Status
Register independent of the VPEN voltage. The appropriate read command are required to be written to the
CUI. Upon initial device powerup or after exit from
powerdown, the device automatically resets to read array mode. In the read array mode, low level input to CE0,
CE1, CE2 and OE, high level input to WE and RESET
and address signals to the address inputs (A22-A0) output the data of the addressed location to the data input/
output (Q15~Q0).
During block erase program or lock-bit configuration
modes, RESET pin at VIL will abort either operation.
Memory array data of the block being altered become
invalid.
When reading information in read array mode, the device defaults to asynchronous page mode. In this state,
data is internally read and stored in a high-speed page
buffer. A2:0 addresses data in the page buffer. The page
size is 4 words or 8 bytes. Asynchronous word/byte mode
is supported with no additional commands required.
In default mode, STS transitions low and remains low
for a maximum time of tPLPH+tPHRH until the reset
operation is complete. Memory contents being altered
are no longer valid; the data may be partially corrupted
after a program or partially altered after an erase or lockbit configuration. Time tPHWL is required after RESET
goes to logic-high (VIH) before another command can
be written.
WRITE
Writes to the CUI enables reading of memory array data,
device identifiers and reading and clearing of the Status
Register and when VPEN=VPENH block erasure program and lock-bit configuration. The CUI is written when
the device is enable, WE is active and OE is at high
level. Address and data are latched on the earlier rising
edge of WE and CE. Standard micro-processor write timings are used.
READ QUERY
The read query operation outputs block status information, CFI (Common Flash Interface) ID string, system
interface information, device geometry information and
MXIC extended query information.
OUTPUT DISABLE
When OE is at VIH, output from the devices is disabled.
Data input/output are in a high-impedance(High-Z) state.

NOTES:
1. Bus operations are defined in Table 2.
2. X = Any valid address within the device.
BA = Address within the block.
IA = Identifier Code Address: see Figure 2 and Table 14.
QA = Query database Address.
PA = Address of memory location to be programmed.
RCD = Data to be written to the read configuration register. This data is presented to the device on A 16-1 ; all other
address inputs are ignored.
3. ID = Data read from Identifier Codes.
QD = Data read from Query database.
SRD = Data read from status register. See Table 15 for a description of the status register bits.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE.
CC = Configuration Code.
4. The upper byte of the data bus (Q8-Q15) during command writes is a "Don't Care" in x16 operation.
5. Following the Read Identifier Codes command, read operations access manufacturer, device and block lock
codes. See Section 4.3 for read identifier code data.
6. If the WSM is running, only Q7 is valid; Q15-Q8 and Q6-Q0 float, which places them in a high impedance state.
7. After the Write to Buffer command is issued check the XSR to make sure a buffer is available for writing.
8. The number of bytes/words to be written to the Write Buffer = N + 1, where N = byte/word count argument.
Count ranges on this device for byte mode are N = 00H to N = 1FH and for word mode are N = 0000H to N =000FH.
The third and consecutive bus cycles, as determined by N, are for writing data into the Write Buffer.
The Confirm command (D0H) is expected after exactly N + 1 write cycles; any other command at that point in the
sequence aborts the write to buffer operation. Please see Figure 4. "Write to Buffer Flowchart" for additional
information.
9. The write to buffer or erase operation does not begin until a Confirm command (D0h) is issued.
10.Attempts to issue a block erase or program to a locked block.
11.Either 40H or 10H are recognized by the WSM as the byte/word program setup.
12.The clear block lock-bits operation simultaneously clears all block lock-bits.

Read Array Command
The device is in Read Array mode on initial device power
up and after exit from power down, or by writing FFH to
the Command User Interface. The read configuration register defaults to asynchronous read page mode. The device remains enabled for reads until another command
is written. The Read Array command functions independently of the VPEN voltage.
Read Query Mode Command
This section defines the data structure or "Database"
returned by the Common Flash Interface (CFI) Query
command. System software should parse this structure
to gain critical information such as block size, density,
x8/x16, and electrical specifications. Once this information has been obtained, the software will know which
command sets to use to enable eLiteFlashTM memory
writes, block erases, and otherwise control the
eLiteFlashTM memory component.
Query Structure Output
The Query Database allows system software to gain information for controlling the eLiteFlashTM memory component. This section describes the device CFI-compliant
interface that allows the host system to access Query
data.
Query data are always presented on the lowest-order
data outputs (DQ 0-7) only. The numerical offset value is
the address relative to the maximum bus width supported
by the device. On this family of devices, the Query table
device starting address is a 10h, which is a word address for x16 devices.
For a word-wide (x16) device, the first two bytes of the
Query structure, "Q" and "R" in ASCII, appear on the
low byte at word addresses 10h and 11h. This CFI-compliant device outputs 00H data on upper bytes. Thus, the
device outputs ASCII "Q" in the low byte (DQ 0-7 ) and
00h in the high byte (DQ 8-15 ).
At Query addresses containing two or more bytes of information, the least significant data byte is presented at
the lower address, and the most significant data byte is
presented at the higher address.

In all of the following tables, addresses and data are represented in hexadecimal notation, so the "h" suffix has been
dropped. In addition, since the upper byte of word-wide devices is always "00h",” the leading "00" has been dropped
from the table notation and only the lower byte value is shown. Any x16 device outputs can be assumed to have 00h
on the upper byte in this mode.

DEVICE OPERATION
SILICON ID READ
The Silicon ID Read mode allows the reading out of a
binary code from the device and will identify its manufacturer and type. This mode is intended for use by
programming equipment for the purpose of automatically
matching the device to be programmed with its corresponding programming algorithm. This mode is functional over the entire temperature range of the device.
During the "Silicon ID Read" Mode, manufacturer's code
(MXIC=C2H) can be read out by setting A0=VIL and
device identifier can be read out by setting A0=VIH.
To terminate the operation, it is necessary to write the
read command. The "Silicon ID Read" command functions independently of the VPEN voltage. This command
is valid only when the WSM is off.
To activate this mode, the two cycle "Silicon ID Read"
command is requested. (The command sequence is illustrated in Table 14.

READ STATUS REGISTER COMMAND
WRITE TO BUFFER COMMAND
The Status Register is read after writing the Read Status
Register command of 70H to the Command User Interface. Also, after starting the internal operation the device is set to the Read Status Register mode automatically.
To program the device, a Write to Buffer command is
issue first. A variable number of bytes, up to the buffer
size, can be loaded into the buffer and written to the
eLiteFlashTM memory device. First, the Write to Buffer
Setup command is issued along with the Block Address
(see Figure 4 ,"Write to Buffer Flowchart" on page26).
After the command is issued, the extended Status Register (XSR) can be read when CE is VIL. XSR.7 indicates if the Write Buffer is available.
The contents of Status Register are latched on the later
falling edge of OE or the first edge of CE0, CE1, CE2
that enables the device OE must be toggle to VIH or the
device must be disable before further reads to update
the status register latch. The Read Status Register command functions independently of the VPEN voltage.
If the buffer is available, the number of words/bytes to
be program is written to the device. Next, the start address is given along with the write buffer data. Subsequent writes provide additional device addresses and
data, depending on the count. After the last buffer data
is given, a Write Confirm command must be issued. The
WSM beginning copy the buffer data to the eLiteFlashTM
memory array.
CLEAR STATUS REGISTER COMMAND
The Erase Status, Program Status, Block Status bits
and protect status are set to "1" by the Write State Machine and can only be reset by the Clear Status Register
command of 50H. These bits indicates various failure
conditions.
If an error occurs while writing, the device will stop writing, and status register bit SR.4 will be set to a "1" to
indicate a program failure. The internal WSM verify only
detects errors for "1" that do not successfully program
to "0" . If a program error is detected, the status register
should be cleared. Any time SR.4 and/or SR.5 is set, the
device will not accept any more Write to Buffer commands. Reliable buffered writes can only occur when VCC
is valid and VPEN = VPENH. Also, successful programming requires that the corresponding block lock-bit be
reset.
BLOCK ERASE COMMAND
Automated block erase is initiated by writing the Block
Erase command of 20H followed by the Confirm command of D0H. An address within the block to be erased
is required (erase changes all block data to FFH).
Block preconditioning, erase, and verify are handled internally by the WSM (invisible to the system). The CPU
can detect block erase completion by analyzing the output of the STS pin or status register bit SR.7. Toggle OE,
CE0 , CE1 , or CE2 to update the status register. The
CUI remains in read status register mode until a new
command is issued. Also, reliable block erasure can only
occur when VCC is valid and VPEN = VPENH.
BYTE/WORD PROGRAM COMMANDS
Byte/Word program is executed by a two-command sequence. The Byte/Word Program Setup command of 40H
is written to the Command Interface, followed by a second write specifying the address and data to be written.
The WSM controls the program pulse application and
verify operation. The CPU can detect the completion of
the program event by analyzing the STS pin or status
register bit SR.7.
If a byte/word program is attempted while VPEN_V
PENLK, status register bits SR.4 and SR.3 will be set to
"1". Successful byte/word programs require that the corresponding block lock-bit be cleared. If a byte/ word program is attempted when the corresponding block lockbit is set, SR.1 and SR.4 will be set to "1".

Configuration Command
The Status (STS) pin can be configured to different states using the Configuration command. Once the STS pin has
been configured, it remains in that configuration until another configuration command is issued or RP is asserted low.
Initially, the STS pin defaults to RY/BY operation where RY/BY low indicates that the state machine is busy. RY/BY
high indicates that the state machine is ready for a new operation. Table 19, "Configuration Coding Definitions" on
page 28 displays the possible STS configurations.
To reconfigure the Status (STS) pin to other modes, the Configuration command is given followed by the desired
configuration code. The three alternate configurations are all pulse mode for use as a system interrupt as described
below. For these configurations, bit 0 controls Erase Complete interrupt pulse, and bit 1 controls Program Complete
interrupt pulse. Supplying the 00h configuration code with the Configuration command resets the STS pin to the
default RY/BY level mode. The possible configurations and their usage are described in Table 19, "Configuration
Coding Definitions" on page 28. The Configuration command may only be given when the device is not busy. Check
SR.7 for device status. An invalid configuration code will result in both status register bits SR.4 and SR.5 being set
to "1". When configured in one of the pulse modes, the STS pin pulses low with a typical pulse width of 250 ns.

Set Block Lock-Bit Commands
This device provided the block lock-bits, to lock and
unlock the individual block. To set the block lock-bit, the
two cycle Set Block Lock-Bit command is requested.
This command is invalid while the WSM is running. Writing the set block lock-bit command of 60H followed by
confirm command and an appropriate block address.
After the command is written, the device automatically
outputs status register data when read. The CPU can
detect the completion of the set lock-bit event by analyzing the STS pin output or status register bit SR.7.
Also, reliable operations occur only when VCC and VPEN
are valid. With VPEN _VPENLK , lock-bit contents are
protected against alteration.
Programming the Protection Register
The protection register bits are programmed using the
two-cycle Protection Program command. The 64-bit number is programmed 16 bits at a time for word-wide parts
and eight bits at a time for byte-wide parts. First write
the Protection Program Setup command, C0H. The next
write to the device will latch in address and data and
program the specified location.
Any attempt to address Protection Program commands
outside the defined protection register address space will
result in a status register error. Attempting to program a
locked protection register segment will result in a status
register error.
Clear Block Lock-Bits Command
All set block lock-bits can clear by the Clear Block LockBits command. This command is invalid while the WSM
is running. To Clear the block lock-bits, two cycle command is requested . The device automatically outputs
status register data when read. The CPU can detect
completion of the clear block lock-bits event by analyzing the STS pin output or status register bit SR.7. If a
clear block lock-bits operation is aborted due to V PEN
or V CC transiting out of valid range, block lock-bit values
are left in an undetermined state. A repeat of clear block
lock-bits is required to initialize block lock-bit contents to
known values.
Locking the Protection Register
The user-programmable segment of the protection register is lockable by programming Bit 1 of the PR-LOCK
location to 0. Bit 0 of this location is programmed to 0 at
the MXIC factory to protect the unique device number.
Bit 1 is set using the Protection Program command to
program "FFFD" to the PR-LOCK location. After these
bits have been programmed, no further changes can be
made to the values stored in the protection register. Protection Program commands to a locked section will result in a status register error. Protection register lockout
state is not reversible.
Protection Register Program Command
The device offer a 128-bit protection register to increase
the security of a system design. The 128-bits protection
register are divided into two 64-bit segments. One is programmed in the factory with a unique 64-bit number,
which is unchangeable. The other one is left blank for
customer designers to program as desired. Once the
customer segment is programmed, it can be locked to
prevent reprogramming.
VCC TRANSITIONS
Block erase, program, and lock-bit configuration are not
guaranteed if VCC falls outside of the specified operating ranges.
The CUI latches commands issued by system software
and is not altered by CE transitions, or WSM actions. Its
state is read array mode upon power-up, after exit from
power-down mode, or after VCC transitions below VLKO.
Reading the Protection Register
The protection register is read in the identification read
mode. The device is switched to this mode by writing the
Read Identifier command 90H. Once in this mode, read
cycles from addresses retrieve the specified informa-

NOTES:
CEX low is defined as the first edge of CE0, CE1, or CE2 that enables the device. CEX high is defined at the first
edge of CE0, CE1, or CE2 that disables the device (see Table 2).
1. Read timing characteristics during block erase, program, and lock-bit configuration operations are the same as
during read-only operations. Refer to AC Characteristics-Read-Only Operations.
2. A write operation can be initiated and terminated with either CE X or WE.
3. Sampled, not 100% tested.
4. Write pulse width (tWP) is defined from CEX or WE going low (whichever goes low last) to CEX or WE going high
(whichever goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH.
5. Refer to Table 4 for valid A IN and D IN for block erase, program, or lock-bit configuration.
6. Write pulse width high (t WPH) is defined from CEX or WE going high (whichever goes high first) to CEX or WE
going low (whichever goes low first). Hence, tWPH = tWHWL = tEHEL = tWHEL = tEHWL .
7. For array access, tAVQV is required in addition to tWHGL for any accesses after a write.
8. STS timings are based on STS configured in its RY/BY default mode.
9. VPEN should be held at VPENH until determination of block erase, program, or lock-bit configuration success
(SR.1/3/4/5=0).
