MX25L3225D
GENERAL DESCRIPTION
The MX25L3225D are 32,554,432 bit serial Flash memory, which is configured as 4,194,304 x 8 internally. When it
is in two or four I/O read mode, the structure becomes 16,777,216 bits x 2 or 8,388,608 bits x 4. The MX25L3225D
feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus
signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access to the device
is enabled by CS# input.
When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# pin and NC pin become SIO0 pin,
SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25L3225D provides sequential read operation on whole chip.
After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify the
specified page or sector/block locations will be executed. Program command is executed on byte basis, or page (256
bytes) basis, or word basis for Continuously program mode, and erase command is executes on sector (4K-byte),
or block (64K-byte), or whole chip basis.
To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read
command can be issued to detect completion status of a program or erase operation via WIP bit.
Advanced security features enhance the protection and security functions, please see security features section for
more details.
When the device is not in operation and CS# is high, it is put in standby mode and draws less than 20uA DC current.
The MX25L3225D utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after
100,000 program and erase cycles.

MX25L3225D
DATA PROTECTION
The MX25L3225D 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 standby 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.
• Valid command length checking: The command length will be checked whether it is at byte base and completed
on byte boundary.
• Write Enable (WREN) command: WREN command is required to set the Write Enable Latch bit (WEL) before
other command to change data. The WEL bit will return to reset stage under following situation:
- Power-up
- Write Disable (WRDI) command completion
- Write Status Register (WRSR) command completion
- Page Program (PP) command completion
- Continuously Program mode (CP) instruction completion
- Sector Erase (SE) command completion
- Block Erase (BE) command completion
- Chip Erase (CE) command completion
• Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from
writing all commands except Release from deep power down mode command (RDP) and Read Electronic Signature command (RES).
• Advanced Security Features: there are some protection and securuity features which protect content from inadvertent write and hostile access.
I. Block lock protection
- The Software Protected Mode (SPM) utilizes (BP3, BP2, BP1, BP0) bits to allow part of memory to be protected as read only. The proected area definition is shown as table of "Protected Area Sizes", the protected areas
are more flexible which may protect various area by setting value of BP0-BP3 bits.
Please refer to table of "protected area sizes".
- The Hardware Proteced Mode (HPM) utilizes WP#/SIO2 to protect the (BP3, BP2, BP1, BP0) bits and SRWD
bit. If the system goes into four I/O read mode, the feature of HPM will be disabled.

II. Additional 4K-bit secured OTP for unique identifier: to provide 4K-bit one-time program area for setting device
unique serial number - Which may be set by factory or system customer. Please refer to table 3. 4K-bit secured
OTP definition.
- Security register bit 0 indicates whether the chip is locked by factory or not.
- To program the 4K-bit secured OTP by entering 4K-bit secured OTP mode (with ENSO command), and going
through normal program procedure, and then exiting 4K-bit secured OTP mode by writing EXSO command.
- Customer may lock-down the customer lockable secured OTP by writing WRSCUR(write security register)
command to set customer lock-down bit1 as "1". Please refer to table of "security register definition" for security
register bit definition and table of "4K-bit secured OTP definition" for address range definition.
- Note: Once lock-down whatever by factory or customer, it cannot be changed any more. While in 4K-bit secured OTP mode, array access is not allowed.

DEVICE OPERATION
1. Before a command is issued, status register should be checked to ensure device is ready for the intended operation.
2. When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode
until next CS# falling edge. In standby mode, SO pin of this LSI should be High-Z.
3. When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until
next CS# rising edge.
4. Input data is latched on the rising edge of Serial Clock(SCLK) and data shifts out on the falling edge of SCLK.
The difference of Serial mode 0 and mode 3 is shown as Figure 2.
5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, 2READ, 4READ,RES, REMS,
REMS2 and REMS4 the shifted-in instruction sequence is followed by a data-out sequence. After any bit of data
being shifted out, the CS# can be high. For the following instructions: WREN, WRDI, WRSR, SE, BE, CE, PP,
4PP, CP, RDP, DP, ENSO, EXSO,and WRSCUR, the CS# must go high exactly at the byte boundary; otherwise,
the instruction will be rejected and not executed.
6. During the progress of Write Status Register, Program, Erase operation, to access the memory array is neglected and not affect the current operation of Write Status Register, Program, Erase.

(1) Write Enable (WREN)
The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP, 4PP,
CP, SE, BE, CE, and WRSR, which are intended to change the device content, should be set every time after the
WREN instruction setting the WEL bit.
The sequence of issuing WREN instruction is: CS# goes low→ sending WREN instruction code→ CS# goes high.
(Please refer to Figure 9)
(2) Write Disable (WRDI)
The Write Disable (WRDI) instruction is for resetting Write Enable Latch (WEL) bit.
The sequence of issuing WRDI instruction is: CS# goes low→ sending WRDI instruction code→ CS# goes high. (Please
refer to Figure 10)
The WEL bit is reset by following situations:
- Power-up
- Write Disable (WRDI) instruction completion
- Write Status Register (WRSR) instruction completion
- Page Program (PP) instruction completion
- Quad Page Program (4PP) instruction completion
- Sector Erase (SE) instruction completion
- Block Erase (BE) instruction completion
- Chip Erase (CE) instruction completion
- Continuously program mode (CP) instruction completion
(3) Read Identification (RDID)
The RDID instruction is for reading the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The Macronix
Manufacturer ID is C2(hex), the memory type ID is 5E(hex) as the first-byte device ID, and the individual device ID
of second-byte ID are listed as table of "ID Definitions". (Please refer to Table 7 in page 25)
The sequence of issuing RDID instruction is: CS# goes low→ sending RDID instruction code → 24-bits ID data out
on SO → to end RDID operation can use CS# to high at any time during data out. (Please refer to Figure 11.)
While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the cycle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby stage.

MX25L3225D
(4) Read Status Register (RDSR)
The RDSR instruction is for reading Status Register Bits. The Read Status Register can be read at any time
(even in program/erase/write status register condition) and continuously. It is recommended to check the Write in
Progress (WIP) bit before sending a new instruction when a program, erase, or write status register operation is in
progress.
The sequence of issuing RDSR instruction is: CS# goes low→ sending RDSR instruction code→ Status Register
data out on SO (see Figure 12)
The definition of the status register bits is as below:
WIP bit. The Write in Progress (WIP) bit, a volatile bit, indicates whether the device is busy in program/erase/write
status register progress. When WIP bit sets to 1, which means the device is busy in program/erase/write status
register progress. When WIP bit sets to 0, which means the device is not in progress of program/erase/write status
register cycle.
WEL bit. The Write Enable Latch (WEL) bit, a volatile bit, indicates whether the device is set to internal write enable
latch. When WEL bit sets to 1, which means the internal write enable latch is set, the device can accept program/
erase/write status register instruction. When WEL bit sets to 0, which means no internal write enable latch; the device will not accept program/erase/write status register instruction. The program/erase command will be ignored and
not affect value of WEL bit if it is applied to a protected memory area.
BP3, BP2, BP1, BP0 bits. The Block Protect (BP3, BP2, BP1, BP0) bits, volatile bits, indicate the protected area(as
defined in table 1) of the device to against the program/erase instruction without hardware protection mode being
set. To write the Block Protect (BP3, BP2, BP1, BP0) bits requires the Write Status Register (WRSR) instruction to
be executed. Those bits define the protected area of the memory to against Page Program (PP), Sector Erase (SE),
Block Erase (BE) and Chip Erase(CE) instructions (only if all Block Protect bits set to 0, the CE instruction can be
executed).
QE bit. The Quad Enable (QE) bit, volatile bit, performs Quad. When it is reset to "0" (factory default) to enable
WP# or is set to "1" to enable Quad SIO2 and SIO3.
SRWD bit. The Status Register Write Disable (SRWD) bit, volatile bit, is operated together with Write Protection (WP#/
SIO2) pin for providing hardware protection mode. The hardware protection mode requires SRWD sets to 1 and
WP#/SIO2 pin signal is low stage. In the hardware protection mode, the Write Status Register (WRSR) instruction is
no longer accepted for execution and the SRWD bit and Block Protect bits (BP3, BP2, BP1, BP0) are read only.

(5) Write Status Register (WRSR)
The WRSR instruction is for changing the values of Status Register Bits. Before sending WRSR instruction, the
Write Enable (WREN) instruction must be decoded and executed to set the Write Enable Latch (WEL) bit in advance. The WRSR instruction can change the value of Block Protect (BP3, BP2, BP1, BP0) bits to define the protected area of memory (as shown in table 1). The WRSR also can set or reset the Quad enable (QE) bit and set or
reset the Status Register Write Disable (SRWD) bit in accordance with Write Protection (WP#/SIO2) pin signal, but
has no effect on bit1(WEL) and bit0 (WIP) of the statur register. The WRSR instruction cannot be executed once the
Hardware Protected Mode (HPM) is entered.
The sequence of issuing WRSR instruction is: CS# goes low→ sending WRSR instruction code→ Status Register
data on SI→ CS# goes high. (please refer to Figure 13)
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
The self-timed Write Status Register cycle time (tW) is initiated as soon as Chip Select (CS#) goes high. The Write
in Progress (WIP) bit still can be check out during the Write Status Register cycle is in progress. The WIP sets 1
during the tW timing, and sets 0 when Write Status Register Cycle is completed, and the Write Enable Latch (WEL)
bit is reset.

As the above table showing, the summary of the Software Protected Mode (SPM) and Hardware Protected Mode (HPM).
Software Protected Mode (SPM):
- When SRWD bit=0, no matter WP#/SIO2 is low or high, the WREN instruction may set the WEL bit and can
change the values of SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1,
BP0, is at software protected mode (SPM).
- When SRWD bit=1 and WP#/SIO2 is high, the WREN instruction may set the WEL bit can change the values of
SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1, BP0, is at software protected mode (SPM)
Note:
If SRWD bit=1 but WP#/SIO2 is low, it is impossible to write the Status Register even if the WEL bit has previously
been set. It is rejected to write the Status Register and not be executed.
P/N: PM1432
REV. 1.0, AUG. 14, 2009

MX25L3225D
Hardware Protected Mode (HPM):
- When SRWD bit=1, and then WP#/SIO2 is low (or WP#/SIO2 is low before SRWD bit=1), it enters the hardware
protected mode (HPM). The data of the protected area is protected by software protected mode by BP3, BP2,
BP1, BP0 and hardware protected mode by the WP#/SIO2 to against data modification.
Note:
To exit the hardware protected mode requires WP#/SIO2 driving high once the hardware protected mode is entered.
If the WP#/SIO2 pin is permanently connected to high, the hardware protected mode can never be entered; only
can use software protected mode via BP3, BP2, BP1, BP0.
If the system goes into four I/O read mode, the feature of HPM will be disabled.
(6) Read Data Bytes (READ)
The read instruction is for reading data out. The address is latched on rising edge of SCLK, and data shifts out on
the falling edge of SCLK at a maximum frequency fR. The first address byte can be at any location. The address
is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can
be read out at a single READ instruction. The address counter rolls over to 0 when the highest address has been
reached.
The sequence of issuing READ instruction is: CS# goes low→ sending READ instruction code→ 3-byte address on
SI→data out on SO→to end READ operation can use CS# to high at any time during data out. (Please refer to Figure 14)
(7) Read Data Bytes at Higher Speed (FAST_READ)
The FAST_READ instruction is for quickly reading data out. The address is latched on rising edge of SCLK, and
data of each bit shifts out on the falling edge of SCLK at a maximum frequency fC. The first address byte can be at
any location. The address is automatically increased to the next higher address after each byte data is shifted out,
so the whole memory can be read out at a single FAST_READ instruction. The address counter rolls over to 0 when
the highest address has been reached.
The sequence of issuing FAST_READ instruction is: CS# goes low→ sending FAST_READ instruction code→3byte address on SI→ 1-dummy byte (default) address on SI→data out on SO→ to end FAST_READ operation can
use CS# to high at any time during data out. (see Figure 15)
While Program/Erase/Write Status Register cycle is in progress, FAST_READ instruction is rejected without any impact on the Program/Erase/Write Status Register current cycle.
(8) 2 x I/O Read Mode (2READ)
The 2READ instruction enable double throughput of Serial Flash in read mode. The address is latched on rising
edge of SCLK, and data of every two bits(interleave on 2 I/O pins) shift out on the falling edge of SCLK at a maximum frequency fT. The first address byte can be at any location. The address is automatically increased to the next
higher address after each byte data is shifted out, so the whole memory can be read out at a single 2READ instruction. The address counter rolls over to 0 when the highest address has been reached. Once writing 2READ instruction, the following address/dummy/data out will perform as 2-bit instead of previous 1-bit.
The sequence of issuing 2READ instruction is: CS# goes low→ sending 2READ instruction→ 24-bit address interleave on SIO1 & SIO0→ 4-bit dummy cycle on SIO1 & SIO0→ data out interleave on SIO1 & SIO0→ to end
2READ operation can use CS# to high at any time during data out (see Figure 16 for 2 x I/O Read Mode Timing
Waveform).
While Program/Erase/Write Status Register cycle is in progress, 2READ instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.

MX25L3225D
(9) 4 x I/O Read Mode (4READ)
The 4READ instruction enable quad throughput of Serial Flash in read mode. A Quad Enable (QE) bit of status Register must be set to "1" before seding the 4READ instruction.The address is latched on rising edge of SCLK, and
data of every four bits(interleave on 4 I/O pins) shift out on the falling edge of SCLK at a maximum frequency fQ.
The first address byte can be at any location. The address is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single 4READ instruction. The address
counter rolls over to 0 when the highest address has been reached. Once writing 4READ instruction, the following
address/dummy/data out will perform as 4-bit instead of previous 1-bit.
The sequence of issuing 4READ instruction is: CS# goes low→ sending 4READ instruction→ 24-bit address interleave on SIO3, SIO2, SIO1 & SIO0→ 6 dummy cycles → data out interleave on SIO3, SIO2, SIO1 & SIO0→ to
end 4READ operation can use CS# to high at any time during data out (see Figure 17 for 4 x I/O Read Mode Timing
Waveform).
Another sequence of issuing 4 READ instruction especially useful in random access is : CS# goes low→ sending 4
READ instruction→ 3-bytes address interleave on SIO3, SIO2, SIO1 & SIO0 → performance enhance toggling bit
P[7:0]→ 4 dummy cycles → data out still CS# goes high → CS# goes low (reduce 4 Read instruction) → 24-bit random access address (see figure 18 for 4x I/O read enhance performance mode timing waveform).
In the performance-enhancing mode (Note of Figure. 18), P[7:4] must be toggling with P[3:0] ; likewise
P[7:0]=A5h,5Ah,F0h or 0Fh can make this mode continue and reduce the next 4READ instruction. Once P[7:4] is
no longer toggling with P[3:0]; likewise P[7:0]=FFh,00h,AAh or 55h. These commands will reset the performance
enhance mode. And afterwards CS# is raised or issuing FF command(CS# goes high → CS# goes low → sending
0xFF → CS# goes high) instead of no toggling,the system then will escape from performance enhance mode and
return to normal opertaion.In these cases,tSHSL=15ns(min) will be specified.
While Program/Erase/Write Status Register cycle is in progress, 4READ instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.
(10) Sector Erase (SE)
The Sector Erase (SE) instruction is for erasing the data of the chosen sector to be "1". The instruction is used for
any 4K-byte sector. A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before
sending the Sector Erase (SE). Any address of the sector (see table 3) is a valid address for Sector Erase (SE)
instruction. The CS# must go high exactly at the byte boundary (the latest eighth of address byte been latched-in);
otherwise, the instruction will be rejected and not executed.
Address bits [Am-A12] (Am is the most significant address) select the sector address.
The sequence of issuing SE instruction is: CS# goes low → sending SE instruction code→ 3-byte address on SI →
CS# goes high. (see Figure 22)
The self-timed Sector Erase Cycle time (tSE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tSE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP3, BP2, BP1, BP0 bits, the Sector Erase (SE) instruction will not be executed on the page.

(11) Block Erase (BE)
The Block Erase (BE) instruction is for erasing the data of the chosen block to be "1". The instruction is used for
64K-byte block erase operation. A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL)
bit before sending the Block Erase (BE). Any address of the block (see table 3) is a valid address for Block Erase (BE)
instruction. The CS# must go high exactly at the byte boundary (the latest eighth of address byte been latched-in);
otherwise, the instruction will be rejected and not executed.
The sequence of issuing BE instruction is: CS# goes low → sending BE instruction code→ 3-byte address on SI
→CS# goes high. (see Figure 23)
The self-timed Block Erase Cycle time (tBE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tBE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP3, BP2, BP1, BP0 bits, the Block Erase (BE) instruction will not be executed on the page.
(12) Chip Erase (CE)
The Chip Erase (CE) instruction is for erasing the data of the whole chip to be "1". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before sending the Chip Erase (CE). The CS# must go
high exactly at the byte boundary( the latest eighth of address byte been latched-in); otherwise, the instruction will
be rejected and not executed.
The sequence of issuing CE instruction is: CS# goes low→ sending CE instruction code→ CS# goes high. (Please
refer to Figure 24)
The self-timed Chip Erase Cycle time (tCE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Chip Erase cycle is in progress. The WIP sets 1 during the tCE
timing, and sets 0 when Chip Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the chip is
protected by BP3, BP2, BP1, BP0 bits, the Chip Erase (CE) instruction will not be executed. It will be only executed
when BP3, BP2, BP1, BP0 all set to "0".
(13) Page Program (PP)
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction
must execute to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). The device programs
only the last 256 data bytes sent to the device. If the entire 256 data bytes are going to be programmed, A7-A0
(The eight least significant address bits) should be set to 0. If the eight least significant address bits (A7-A0) are not
all 0, all transmitted data going beyond the end of the current page are programmed from the start address of the
same page (from the address A7-A0 are all 0). If more than 256 bytes are sent to the device, the data of the last
256-byte is programmed at the request page and previous data will be disregarded. If less than 256 bytes are sent
to the device, the data is programmed at the requested address of the page without effect on other address of the
same page.
The sequence of issuing PP instruction is: CS# goes low→ sending PP instruction code→ 3-byte address on SI→ at
least 1-byte on data on SI→ CS# goes high. (see Figure 19)
The CS# must be kept to low during the whole Page Program cycle; The CS# must go high exactly at the byte
boundary( the latest eighth bit of data being latched in), otherwise the instruction will be rejected and will not be executed.
The self-timed Page Program Cycle time (tPP) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Page Program cycle is in progress. The WIP sets 1 during the
tPP timing, and sets 0 when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the
page is protected by BP3, BP2, BP1, BP0 bits, the Page Program (PP) instruction will not be executed.

(14) 4 x I/O Page Program (4PP)
The Quad Page Program (4PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit and Quad Enable (QE) bit must be set to "1" before
sending the Quad Page Program (4PP). The Quad Page Programming takes four pins: SIO0, SIO1, SIO2, and
SIO3, which can raise programer performance and and the effectiveness of application of lower clock less than
20MHz. For system with faster clock, the Quad page program cannot provide more actual favors, because the required internal page program time is far more than the time data flows in. Therefore, we suggest that while executing this command (especially during sending data), user can slow the clock speed down to 20MHz below. The other
function descriptions are as same as standard page program.
The sequence of issuing 4PP instruction is: CS# goes low→ sending 4PP instruction code→ 3-byte address on
SIO[3:0]→ at least 1-byte on data on SIO[3:0]→ CS# goes high. (see Figure 20)
(15) Continuously program mode (CP mode)
The CP mode may enhance program performance by automatically increasing address to the next higher address
after each byte data has been programmed.
The Continuously program (CP) instruction is for multiple byte program to Flash. A write Enable (WREN) instruction must execute to set the Write Enable Latch(WEL) bit before sending the Continuously program (CP) instruction.
CS# requires to go high before CP instruction is executing. After CP instruction and address input, two bytes of data
is input sequentially from MSB(bit7) to LSB(bit0). The first byte data will be programmed to the initial address range
with A0=0 and second byte data with A0=1. If only one byte data is input, the CP mode will not process. If more
than two bytes data are input, the additional data will be ignored and only two byte data are valid. The CP program
instruction will be ignored and not affect the WEL bit if it is applied to a protected memory area. Any byte to be programmed should be in the erase state (FF) first. It will not roll over during the CP mode, once the last unprotected
address has been reached, the chip will exit CP mode and reset write Enable Latch bit (WEL) as "0" and CP mode
bit as "0". Please check the WIP bit status if it is not in write progress before entering next valid instruction. During
CP mode, the valid commands are CP command (AD hex), WRDI command (04 hex), RDSR command (05 hex),
and RDSCUR command (2B hex). And the WRDI command is valid after completion of a CP programming cycle,
which means the WIP bit=0.
The sequence of issuing CP instruction is : CS# high to low→ sending CP instruction code→ 3-byte address on SI->
Data Byte on SI→CS# goes high to low→ sending CP instruction......→ last desired byte programmed or sending
Write Disable (WRDI) instruction to end CP mode→ sending RDSR instruction to verify if CP mode is ended. (see
Figure 21 of CP mode timing waveform)
Three methods to detect the completion of a program cycle during CP mode:
1) Software method-I: by checking WIP bit of Status Register to detect the completion of CP mode.
2) Software method-II: by waiting for a tBP time out to determine if it may load next valid command or not.
3) Hardware method: by writing ESRY (enable SO to output RY/BY#) instruction to detect the completion of a program cycle during CP mode. The ESRY instruction must be executed before CP mode execution. Once it is
enable in CP mode, the CS# goes low will drive out the RY/BY# status on SO, "0" indicates busy stage, "1" indicates ready stage, SO pin outputs tri-state if CS# goes high. DSRY (disable SO to output RY/BY#) instruction to
disable the SO to output RY/BY# and return to status register data output during CP mode. Please note that the
ESRY/DSRY command are not accepted unless the completion of CP mode.

(16) Deep Power-down (DP)
The Deep Power-down (DP) instruction is used to set the device on minimizing the power consumption (to enter the
Deep Power-down mode, the standby current is reduced from ISB1 to ISB2). The Deep Power-down mode requires
the Deep Power-down (DP) instruction to enter, during the Deep Power-down mode, the device is not active and all
Write/Program/Erase instruction are ignored. When CS# goes high, it's only in standby mode not deep power-down
mode. It's different from Standby mode.
The sequence of issuing DP instruction is: CS# goes low→ sending DP instruction code→ CS# goes high. (Please
refer to Figure 25)
Once the DP instruction is set, all instruction will be ignored except the Release from Deep Power-down mode (RDP)
and Read Electronic Signature (RES) instruction. (those instructions allow the ID being reading out). When Powerdown, the deep power-down mode automatically stops, and when power-up, the device automatically is in standby
mode. For RDP instruction the CS# must go high exactly at the byte boundary (the latest eighth bit of instruction
code been latched-in); otherwise, the instruction will not executed. As soon as Chip Select (CS#) goes high, a delay
of tDP is required before entering the Deep Power-down mode and reducing the current to ISB2.
(17) Release from Deep Power-down (RDP), Read Electronic Signature (RES)
The Release from Deep Power-down (RDP) instruction is terminated by driving Chip Select (CS#) High. When Chip
Select (CS#) is driven High, the device is put in the Stand-by Power mode. If the device was not previously in the
Deep Power-down mode, the transition to the Stand-by Power mode is immediate. If the device was previously in
the Deep Power-down mode, though, the transition to the Stand-by Power mode is delayed by tRES2, and Chip Select (CS#) must remain High for at least tRES2(max), as specified in Table 6. Once in the Stand-by Power mode, the
device waits to be selected, so that it can receive, decode and execute instructions.
RES instruction is for reading out the old style of 8-bit Electronic Signature, whose values are shown as table of ID
Definitions. This is not the same as RDID instruction. It is not recommended to use for new design. For new design,
please use RDID instruction. Even in Deep power-down mode, the RDP and RES are also allowed to be executed,
only except the device is in progress of program/erase/write cycle; there's no effect on the current program/erase/
write cycle in progress.
The sequence is shown on Figure 26,27.
The RES instruction is ended by CS# goes high after the ID been read out at least once. The ID outputs repeatedly if continuously send the additional clock cycles on SCLK while CS# is at low. If the device was not previously
in Deep Power-down mode, the device transition to standby mode is immediate. If the device was previously in
Deep Power-down mode, there's a delay of tRES2 to transit to standby mode, and CS# must remain to high at least
tRES2(max). Once in the standby mode, the device waits to be selected, so it can be receive, decode, and execute
instruction.
The RDP instruction is for releasing from Deep Power Down Mode.
(18) Read Electronic Manufacturer ID & Device ID (REMS), (REMS2), (REMS4)
The REMS, REMS2 & REMS4 instruction is an alternative to the Release from Power-down/Device ID instruction
that provides both the JEDEC assigned manufacturer ID and the specific device ID.
The sequence of issuing DP instruction is: CS# goes low→sending DP instruction code→ CS# goes high. (Please
refer to Figure 27)
The REMS, REMS2 & REMS4 instruction is very similar to the Release from Power-down/Device ID instruction. The
instruction is initiated by driving the CS# pin low and shift the instruction code "90h" or "EFh" or "DFh"followed by
two dummy bytes and one bytes address (A7~A0). After which, the Manufacturer ID for MXIC (C2h) and the Device
ID are shifted out on the falling edge of SCLK with most significant bit (MSB) first as shown in figure 31. The Device
ID values are listed in Table of ID Definitions. If the one-byte address is initially set to 01h, then the device ID will be
read first and then followed by the Manufacturer ID. The Manufacturer and Device IDs can be read continuously, alternating from one to the other. The instruction is completed by driving CS# high.

(19) Enter Secured OTP (ENSO)
The ENSO instruction is for entering the additional 4K-bit secured OTP mode. The additional 4K-bit secured OTP is
independent from main array, which may use to store unique serial number for system identifier. After entering the
Secured OTP mode, and then follow standard read or program, procedure to read out the data or update data. The
Secured OTP data cannot be updated again once it is lock-down.
The sequence of issuing ENSO instruction is: CS# goes low→ sending ENSO instruction to enter Secured OTP
mode → CS# goes high.
Please note that WRSR/WRSCUR commands are not acceptable during the access of secure OTP region, once security OTP is lock down, only read related commands are valid.
(20) Exit Secured OTP (EXSO)
The EXSO instruction is for exiting the additional 4K-bit secured OTP mode.
The sequence of issuing EXSO instruction is: CS# goes low→ sending EXSO instruction to exit Secured OTP
mode→ CS# goes high.
(21) Read Security Register (RDSCUR)
The RDSCUR instruction is for reading the value of Security Register bits. The Read Security Register can be read
at any time (even in program/erase/write status register/write security register condition) and continuously.
The sequence of issuing RDSCUR instruction is : CS# goes low→ send ing RDSCUR instruction → Security Register data out on SO→ CS# goes high.
The definition of the Security Register bits is as below:
Secured OTP Indicator bit. The Secured OTP indicator bit shows the chip is locked by factory before ex- factory or
not. When it is "0", it indicates non- factory lock; "1" indicates factory- lock.
Lock-down Secured OTP (LDSO) bit. By writing WRSCUR instruction, the LDSO bit may be set to "1" for customer lock-down purpose. However, once the bit is set to "1" (lock-down), the LDSO bit and the 4K-bit Secured OTP
area cannot be update any more. While it is in 4K-bit secured OTP mode, array access is not allowed.
Continuously Program Mode( CP mode) bit. The Continuously Program Mode bit indicates the status of CP
mode, "0" indicates not in CP mode; "1" indicates in CP mode.

(22) Write Security Register (WRSCUR)
The WRSCUR instruction is for changing the values of Security Register Bits. Unlike write status register, the WREN
instruction is not required before sending WRSCUR instruction. The WRSCUR instruction may change the values
of bit1 (LDSO bit) for customer to lock-down the 4K-bit Secured OTP area. Once the LDSO bit is set to "1", the Secured OTP area cannot be updated any more.
The sequence of issuing WRSCUR instruction is :CS# goes low→ sending WRSCUR instruction → CS# goes high.
The CS# must go high exactly at the boundary; otherwise, the instruction will be rejected and not executed.

POWER-ON STATE
The device is states when power-up as following:
- Standby mode ( please note it is not deep power-down mode)
- Write Enable Latch (WEL) bit is reset
The device must not be selected during power-up and power-down stage unless the VCC achieves below correct
level:
- VCC minimum at power-up stage and then after a delay of tVSL
- GND at power-down
Please note that a pull-up resistor on CS# may ensure a safe and proper power-up/down level.
An internal power-on reset (POR) circuit may protect the device from data corruption and inadvertent data change
during power up state.
For further protection on the device, if the VCC does not reach the VCC minimum level, the correct operation is not
guaranteed. The read, write, erase, and program command should be sent after the below time delay:
- tVSL after VCC reached VCC minimum level
The device can accept read command after VCC reached VCC minimum and a time delay of tVSL.
Please refer to the figure of "power-up timing".
Note:
- To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommended.(generally around 0.1uF)

Note: (1) During CP mode, the valid commands are CP command (AD hex), WRDI command (04 hex), RDSR command (05 hex), and RDSCUR command (2B hex).
(2) Once an internal programming operation begins, CS# goes low will drive the status on the SO pin and
CS# goes high will return the SO pin to tri-state.
(3) To end the CP mode, either reaching the highest unprotected address or sending Write Disable (WRDI)
command (04 hex) may achieve it and then it is recommended to send RDSR command (05 hex) to verify if
CP mode is ended
