MX25L3235D
GENERAL DESCRIPTION
The MX25L3235D 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 MX25L3235D 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 MX25L3235D 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 MX25L3235D utilizes MXIC's proprietary memory cell, which reliably stores memory contents even after 100,000
program and erase cycles.

DATA PROTECTION
The MX25L3235D 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.
•
Power-on reset and tPUW: to avoid sudden power switch by system power supply transition, the power-on reset and
tPUW (internal timer) may protect the Flash.
• 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) use (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) use 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. (see
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. (see 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 MXIC
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". (see table 7 in page 26)
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. (see 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.

REV. 1.1, OCT. 14, 2008
MX25L3235D
(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, non-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, non-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, non-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. (see Figure 13)
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. The selftimed 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: PM1383

REV. 1.1, OCT. 14, 2008
MX25L3235D
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. (see 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-> 3-byte
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.

(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 64Kbyte block erase operation. A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL) bit before
P/N: PM1383
20
REV. 1.1, OCT. 14, 2008
MX25L3235D
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. (see 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
P/N: PM1383
21
REV. 1.1, OCT. 14, 2008
MX25L3235D
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)
P/N: PM1383
22
REV. 1.1, OCT. 14, 2008
MX25L3235D
The Deep Power-down (DP) instruction is for setting the device on the minimizing the power consumption (to entering 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. (see 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 Power-down, 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 Powerdown 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 as 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 Powerdown 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 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 lockdown 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 at below states when power-up:
- 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. When VCC is lower than VWI (POR threshold voltage value), the internal logic is reset and the flash device
has no response to any command.
For further protection on the device, after VCC reaching the VWI level, a tPUW time delay is required before the device
is fully accessible for commands like write enable(WREN), page program (PP), Continuously Program (CP), sector
erase(SE), chip erase(CE), WRSCUR and write status register(WRSR). If the VCC does not reach the VCC minimum level,
the correct operation is not guaranteed. The write, erase, and program command should be sent after the below time delay:
- tPUW after VCC reached VWI level
- tVSL after VCC reached VCC minimum level
The device can accept read command after VCC reached VCC minimum and a time delay of tVSL, even time of tPUW
has not passed.
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)
- At power-down stage, the VCC drops below VWI level, all operations are disable and device has no response to any
command. The data corruption might occur during the stage while a write, program, erase cycle is in progress.

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
