GENERAL DESCRIPTION  
The MX25U2033E is 2,097,152 bit serial Flash memory, which is configured as 1,048,576 x 2 internally. The  
MX25U2033E features a serial peripheral interface and software protocol allowing operation on a simple 4-wire bus  
while it is in single I/O mode. The four bus signals are a clock input (SCLK), a serial data input (SI), a serial data  
output (SO) and a chip select (CS#). 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 HOLD# pin become SIO0  
pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.  
The MX25U2033E MXSMIO® (Serial Multi I/O) provides sequential read operation on the 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. Erase command is executed on 4K-byte sector, 32K-byte block, or 64K-byte block, or whole chip  
basis.

MX25U2033E  
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 the 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 typically draws 25uA DC current.  
The MX25U2033E utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after  
100,000 program and erase cycles.

5. DATA PROTECTION  
During power transition, there may be some false system level signals which result in inadvertent erasure or pro-  
gramming. The device is designed to protect itself from these accidental write cycles.  
The state machine will be reset as standby mode automatically during power up. In addition, the control register ar-  
chitecture of the device constrains that the memory contents can only be changed after specific command sequenc-  
es have completed successfully.  
In the following, there are several features to protect the system from the accidental write cycles during VCC pow-  
erup and power-down or from 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 is-  
suing other commands to change data. The WEL bit will return to resetting stage while the following conditions  
occurred:  
- Power-up  
- Completion of Write Disable (WRDI) command  
- Completion of Write Status Register (WRSR) command  
- Completion of Page Program (PP) command  
- Completion of Quad page program (4PP) command  
- Completion of Sector Erase (SE) command  
- Completion of Block Erase 32KB (BE32K) command  
- Completion of Block Erase (BE) command  
- Completion of Chip Erase (CE) command  
- Completion of Write Protection Select (WPSEL) command  
- Completion of Write Security Register (WRSCUR) command  
- Completion of Single Block Lock/Unlock (SBLK/SBULK) command  
- Completion of Gang Block Lock/Unlock (GBLK/GBULK) command  
Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from writ-  
ing 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 security features which protect content from inad-  
vertent write and hostile access.  
I. Block lock protection  
- The Software Protected Mode (SPM) use (BP2, BP1, BP0) bits to allow part of memory to be protected as read  
only. The protected area definition is shown as table of "Table 2. Protected Area Sizes", the protected areas are  
more flexible which may protect various area by setting value of BP0-BP2 bits.  
Please refer to table of "Table 2. Protected Area Sizes".  
- The Hardware Protected Mode (HPM) use WP#/SIO2 to protect the (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 de-  
vice unique serial number - Which may be set by factory or system maker. Please refer to "Table 3. 4K-bit Se-  
cured 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 9. Security Register Definition" for secu-  
rity register bit definition and "Table 3. 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.

7. DEVICE OPERATION  
1. Before a command is issued, status register should be checked to ensure device is ready for the intended op-  
eration.  
2. When incorrect command is inputted to this device, it enters standby mode and remains in standby mode until  
next CS# falling edge. In standby mode, SO pin of the device is High-Z.  
3. When correct command is inputted to this device, it enters active mode and remains in active mode until next  
CS# rising edge.  
4. Input data is latched on the rising edge of Serial Clock (SCLK) and data is shifted out on the falling edge of  
SCLK. The difference of Serial mode 0 and mode 3 is shown as "Figure 1. Serial Modes Supported" .  
5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, RDSFDP, 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,  
BE32K, BE, CE, PP, 4PP, RDP, DP, WPSEL, SBLK, SBULK, GBLK, GBULK,ENSO, EXSO, and WRSCUR, the  
CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.  
6. While a Write Status Register, Program or Erase operation is in progress, access to the memory array is ne-  
glected and will not affect the current operation of WRSCUR, WPSEL Write Status Register, Program and Erase.

8. HOLD FEATURE  
HOLD# pin signal goes low to hold any serial communications with the device. The HOLD feature will not stop the  
operation of write status register, programming, or erasing in progress.  
The operation of HOLD requires Chip Select (CS#) keeping low and starts on falling edge of HOLD# pin signal while  
Serial Clock (SCLK) signal is being low (if Serial Clock signal is not being low, HOLD operation will not start until Se-  
rial Clock signal being low). The HOLD condition ends on the rising edge of HOLD# pin signal while Serial Clock (SCLK)  
signal is being low (if Serial Clock signal is not being low, HOLD operation will not end until Serial Clock being low),  
see "Figure 2. Hold Condition Operation".

The Serial Data Output (SO) is high impedance, both Serial Data Input (SI) and Serial Clock (SCLK) are don't care  
during the HOLD operation. If Chip Select (CS#) drives high during HOLD operation, it will reset the internal logic of  
the device. To re-start communication with chip, the HOLD# must be at high and CS# must be at low.

Write Enable (WREN)  
The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP, 4PP,  
SE, BE32K, BE, CE, WPSEL, WRSCUR, SBLK, SBULK, GBLK, GBULK and WRSR, which are intended to change  
the device content WEL bit 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 14. Write Enable (WREN) Sequence (Command 06)")  
9-2.  
Write Disable (WRDI)  
The Write Disable (WRDI) instruction is to reset 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 15. Write Disable (WRDI) Sequence (Command 04)")  
The WEL bit is reset by following situations:  
- Power-up  
- Completion of Write Disable (WRDI) instruction  
- Completion of Write Status Register (WRSR) instruction  
- Completion of Page Program (PP) instruction  
- Completion of Quad Page Program (4PP) instruction  
- Completion of Sector Erase (SE) instruction  
- Completion of Block Erase 32KB (BE32K) instruction  
- Completion of Block Erase (BE) instruction  
- Completion of Chip Erase (CE) instruction  
- Completion of Write Protection Select (WPSEL) instruction  
- Completion of Write Security Register (WRSCUR) instruction  
- Completion of Single Block Lock/Unlock (SBLK/SBULK) instruction  
- Completion of Gang Block Lock/Unlock (GBLK/GBULK) instruction  
9-3.  
Read Identification (RDID)  
The RDID instruction is to read the manufacturer ID of 1-byte and followed by Device ID of 2-byte. The MXIC Manu-  
facturer ID is C2(hex), the memory type ID is 25(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 8. ID Definitions")  
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 drive CS# to high at any time during data out. (Please refer to "Figure 16. Read  
Identification (RDID) Sequence (Command 9F)")  
While Program/Erase operation is in progress, it will not decode the RDID instruction, therefore 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.  
9-4.  
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/WPSEL/WRSCUR/write status register condition). 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 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 sta-  
tus 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 if it is ap-  
plied to a protected memory area. To ensure both WIP bit & WEL bit are both set to 0 and available for next program/  
erase/operations, WIP bit needs to be confirm to be 0 before polling WEL bit. After WIP bit confirmed, WEL bit needs  
to be confirm to be 0.  
BP2, BP1, BP0 bits. The Block Protect (BP2, BP1, BP0) bits, non-volatile bits, indicate the protected area (as defined  
in "Table 2. Protected Area Sizes") of the device to against the program/erase instruction without hardware protection  
mode being set. To write the Block Protect (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 32KB (BE32K), Block Erase (BE) and Chip Erase (CE) instructions (only if Block Protect bits (BP2:BP0)  
set to 0, the CE instruction can be executed). The BP2, BP1, BP0 bits are "0" as default. Which is un-protected.  
QE bit. The Quad Enable (QE) bit, non-volatile bit, while it is "0" (factory default), it performs non-Quad and WP# is  
enable. While QE is "1", it performs Quad I/O mode and WP# is disabled. In the other word, if the system goes into  
four I/O mode (QE=1), the features of HPM and HOLD will be disabled.  
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 (BP2, BP1, BP0) are read only. The SRWD  
bit defaults to be "0".

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 ad-  
vance. The WRSR instruction can change the value of Block Protect (BP2, BP1, BP0) bits to define the protected  
area of memory (as shown in "Table 2. Protected Area Sizes"). 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 status 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 18. Write Status Register (WRSR) Sequence (Command 01)"  
)
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.

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, BP2, BP1, BP0. The protected area, which is defined by 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, BP2, BP1, BP0. The protected area, which is defined by 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.

REV. 1.3, NOV. 14, 2013

MX25U2033E  
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 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 BP2, BP1, BP0.  
If the system enter Quad I/O QE=1, the feature of HPM will be disabled.  
9-6.  
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 19. Read Data Bytes (READ) Sequence (Command 03) (50MHz)")  
9-7.  
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. (Please refer to "Figure 20. Read at Higher Speed (FAST_READ)  
Sequence (Command 0B)")  
While Program/Erase/Write Status Register cycle is in progress, FAST_READ instruction is rejected without any im-  
pact on the Program/Erase/Write Status Register current cycle.  
9-8.  
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 maxi-  
mum 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 instruc-  
tion. The address counter rolls over to 0 when the highest address has been reached. Once writing 2READ instruc-  
tion, the following address/dummy/data out will perform as 2-bit instead of previous 1-bit.

operation can use CS# to high at any time during data out (Please refer to "Figure 21. 2 x I/O Read Mode Sequence  
(Command BB)").  
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.  
9-9.  
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 Reg-  
ister must be set to "1" before sending 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 af-  
ter 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.

In the performance-enhancing mode, 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]; like-  
wise P[7:0]=FFh,00h,AAh or 55h and afterwards CS# is raised and then lowered, the system then will escape from  
performance enhance mode and return to normal operation.  
9-11. 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 4. Memory Organization") is a valid address  
for Sector Erase (SE) instruction. The CS# must go high exactly at the byte boundary (the least significant bit of the  
address 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. (Please refer to "Figure 26. Sector Erase (SE) Sequence (Command 20)")  
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 checked while the Sector Erase cycle is in progress. The WIP sets during the tSE  
timing, and clears when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the  
sector is protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Sector Erase (SE) instruction will  
not be executed on the sector.

9-12. Block Erase (BE32K)  
The Block Erase (BE32K) instruction is for erasing the data of the chosen block to be "1". The instruction is used  
for 32K-byte block erase operation. A Write Enable (WREN) instruction must be executed to set the Write Enable  
Latch (WEL) bit before sending the Block Erase (BE32K). Any address of the block (see "Table 4. Memory Organi-  
zation") is a valid address for Block Erase (BE32K) instruction. The CS# must go high exactly at the byte boundary (the  
least significant bit of address byte been latched-in); otherwise, the instruction will be rejected and not executed.  
The sequence of issuing BE32K instruction is: CS# goes low→ sending BE32K instruction code→ 3-byte address  
on SI→CS# goes high. (Please refer to "Figure 27. Block Erase 32KB (BE32K) Sequence (Command 52)")  
The self-timed Block Erase Cycle time (tBE32K) is initiated as soon as Chip Select (CS#) goes high. The Write in  
Progress (WIP) bit still can be checked while he Block Erase cycle is in progress. The WIP sets during the tBE32K  
timing, and clears when Block Erase Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the  
block is protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Block Erase (tBE32K) instruction  
will not be executed on the block.  
9-13. 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 be executed to set the Write Enable  
Latch (WEL) bit before sending the Block Erase (BE). Any address of the block (Please refer to "Table 4. Memory  
Organization") is a valid address for Block Erase (BE) instruction. The CS# must go high exactly at the byte boundary (the  
least significant bit 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. (Please refer to "Figure 28. Block Erase (BE) Sequence (Command D8)")  
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 checked while the Block Erase cycle is in progress. The WIP sets during the tBE  
timing, and clears when Block Erase Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the  
block is protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Block Erase (BE) instruction will not  
be executed on the block.  
9-14. Chip Erase (CE)  
The Chip Erase (CE) instruction is for erasing the data of the whole chip to be "1". A Write Enable (WREN) instruc-  
tion must be executed to set the Write Enable Latch (WEL) bit before sending the Chip Erase (CE). The CS# must  
go high exactly at the byte boundary, 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 29. Chip Erase (CE) Sequence (Command 60 or C7)")  
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 checked while the Chip Erase cycle is in progress. The WIP sets during the tCE tim-  
ing, and clears when Chip Erase Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the chip is  
protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Chip Erase (CE) instruction will not be ex-  
ecuted. It will be only executed when BP2, BP1, BP0 all set to "0".

MX25U2033E  
9-15. Page Program (PP)  
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction  
must be executed to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). The device pro-  
grams 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 cleared. The last address byte (the 8 least significant address  
bits, A7-A0) should be set to 0 for 256 bytes page program. If A7-A0 are not all zero, transmitted data that exceed  
page length are programmed from the starting address (24-bit address that last 8 bit are all 0) of currently selected  
page. If the data bytes sent to the device exceeds 256, the last 256 data byte is programmed at the request page  
and previous data will be disregarded. If the data bytes sent to the device has not exceeded 256, the data will be  
programmed at the request address of the page. There will be no effort on the other data bytes 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. (Please refer to "Figure 24. Page Program (PP) Sequence (Command  
02)")  
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 ex-  
ecuted.  
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 checked while the Page Program cycle is in progress. The WIP sets during the tPP  
timing, and clears when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the  
page is protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Page Program (PP) instruction will  
not be executed.  
9-16. 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) in-  
struction must be executed 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 as address and data input, which can improve programmer performance and the effectiveness of applica-  
tion of lower clock less than 70MHz. For system with faster clock, the Quad page program cannot provide more per-  
formance, 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  
70MHz 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. (Please refer to "Figure 25. 4 x I/O Page Program (4PP)  
Sequence (Command 38)")  
If the page protected by BP2 ~ 0 (WPSEL=0) or by individual lock (WPSEL=1), the Quad page program (4PP)  
instruction will not be executed.  
9-17. Deep Power-down (DP)  
The Deep Power-down (DP) instruction is for setting the device to minimize the power consumption (the standby  
current is reduced from ISB1 to ISB2). The Deep Power-down mode requires the Deep Power-down (DP) instruc-  
tion to enter, during the Deep Power-down mode, the device is not active and all Write/Program/Erase instruction  
are ignored.  
The sequence of issuing DP instruction is: CS# goes low→sending DP instruction code→CS# goes high.  
(Please refer to "Figure 30. Deep Power-down (DP) Sequence (Command B9)")  
P/N: PM1743  
REV. 1.3, NOV. 14, 2013  
27  
MX25U2033E  
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, or software reset command the deep power-down mode automatically stops, and when power-up, the device  
automatically is in standby mode. For DP 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.  
9-18. Release from Deep Power-down (RDP), Read Electronic Signature (RES)  
The Release from Deep Power-down (RDP) instruction is completed 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 Se-  
lect (CS#) must remain High for at least tRES2 (max), as specified in "Table 14. AC Characteristics". AC Character-  
istics. Once in the Stand-by Power mode, the device waits to be selected, so that it can receive, decode and execute  
instructions. The RDP instruction is only for releasing from Deep Power Down Mode.  
RES instruction is for reading out the old style of 8-bit Electronic Signature, whose values are shown as table of ID  
Definitions on next page. This is not the same as RDID instruction. It is not recommended to use for new design.  
For new design, please use RDID instruction.  
The sequence is shown as "Figure 31. RDP and Read Electronic Signature (RES) Sequence (Command AB)" and  
"Figure 32. Release from Deep Power-down (RDP) Sequence (Command AB)". 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 cy-  
cle; there's no effect on the current program/erase/write cycle in progress.  
The RES instruction is ended by CS# goes high after the ID been read out at least once. The ID outputs repeat-  
edly 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.  
9-19. Read Electronic Manufacturer ID & Device ID (REMS), (REMS2), (REMS4)  
The REMS, REMS2 and REMS4 instruction provides both the JEDEC assigned Manufacturer ID and the specific  
Device ID.  
The instruction is initiated by driving the CS# pin low and shift the instruction code "90h", "DFh" or "EFh" followed  
by two dummy bytes and one bytes address (A7~A0). After which, the Manufacturer ID for MXIC (C2h) and the De-  
vice ID are shifted out on the falling edge of SCLK with most significant bit (MSB) first as shown in "Figure 33. Read  
Electronic Manufacturer & Device ID (REMS) Sequence (Command 90/EF/DF)". 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 fol-  
lowed 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.

9-20. Enter Secured OTP (ENSO)  
The ENSO instruction is for entering the additional 4K-bit secured OTP mode. While device is in 4K-bit secured  
OTP mode, main array access is not available. The additional 4K-bit secured OTP is independent from main array,  
and may be used to store unique serial number for system identifier. After entering the Secured OTP mode, 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/WPSEL commands are not acceptable during the access of secure OTP region,  
once security OTP is lock down, only read related commands are valid.  
9-21. 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.  
9-22. 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→sending RDSCUR instruction→Security Register  
data out on SO→ CS# goes high. (Please see "Figure 34. Read Security Register (RDSCUR) Sequence (Command  
2B)")  
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 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 cus-  
tomer 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 updated any more.

9-23. Write Security Register (WRSCUR)  
The WRSCUR instruction is for setting the values of Security Register Bits. The WREN (Write Enable) instruction is  
required before issuing 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 LDSO bit is an OTP bit. Once the LDSO bit is set, the value of LDSO bit can not  
be altered any more.  
The sequence of issuing WRSCUR instruction is :CS# goes low→ sending WRSCUR instruction → CS# goes high.  
(Please see "Figure 35. Write Security Register (WRSCUR) Sequence (Command 2F)".)  
The CS# must go high exactly at the boundary; otherwise, the instruction will be rejected and not executed.  
9-24. Write Protection Selection (WPSEL)  
When the system accepts and executes WPSEL instruction, bit 7 in the security register will be set. The WREN (Write  
Enable) instruction is required before issuing WPSEL instruction. It will activate SBLK, SBULK, RDBLOCK, GBLK,  
GBULK etc instructions to conduct block lock protection and replace the original Software Protect Mode (SPM) use  
(BP2~BP0) indicated block methods.  
The sequence of issuing WPSEL instruction is: CS# goes low → sending WPSEL instruction to enter the individual  
block protect mode→ CS# goes high.  
Every time after the system is powered-on, the Security Register bit 7 is checked. If WPSEL=1, then all the blocks  
and sectors will be write-protected by default. User may only unlock the blocks or sectors via SBULK and GBULK  
instructions. Program or erase functions can only be operated after the Unlock instruction is executed.  
Once WPSEL is set, it cannot be changed.

9-25. Single Block Lock/Unlock Protection (SBLK/SBULK)  
These instructions are only effective after WPSEL was executed. The SBLK instruction is for write protection a  
specified block (or sector) of memory, using AMAX-A16 or (AMAX-A12) address bits to assign a 64Kbyte block (or 4K  
bytes sector) to be protected as read only. The SBULK instruction will cancel the block (or sector) write protection  
state. This feature allows user to stop protecting the entire block (or sector) through the chip unprotect command  
(GBULK).  
The WREN (Write Enable) instruction is required before issuing SBLK/SBULK instruction.  
The sequence of issuing SBLK/SBULK instruction is: CS# goes low → send SBLK/SBULK (36h/39h)  
instruction→send 3 address bytes assign one block (or sector) to be protected on SI pin → CS# goes high. The CS#  
must go high exactly at the byte boundary, otherwise the instruction will be rejected and not be executed.

9-26. Read Block Lock Status (RDBLOCK)  
This instruction is only effective after WPSEL was executed. The RDBLOCK instruction is for reading the status  
of protection lock of a specified block (or sector), using AMAX-A16 (or AMAX-A12) address bits to assign a 64K bytes  
block (4K bytes sector) and read protection lock status bit which the first byte of Read-out cycle. The status bit is "1"  
to indicate that this block has be protected, that user can read only but cannot write/program /erase this block. The  
status bit is "0" to indicate that this block hasn't be protected, and user can read and write this block.  
The sequence of issuing RDBLOCK instruction is: CS# goes low → send RDBLOCK (3Ch) instruction → send 3  
address bytes to assign one block on SI pin → read block's protection lock status bit on SO pin → CS# goes high.  
9-27. Gang Block Lock/Unlock (GBLK/GBULK)  
These instructions are only effective after WPSEL was executed. The GBLK/GBULK instruction is for enable/disable  
the lock protection block of the whole chip.  
The WREN (Write Enable) instruction is required before issuing GBLK/GBULK instruction.  
The sequence of issuing GBLK/GBULK instruction is: CS# goes low → send GBLK/GBULK (7Eh/98h) instruction  
→CS# goes high.  
The CS# must go high exactly at the byte boundary, otherwise, the instruction will be rejected and not be executed.

9-28. Read SFDP Mode (RDSFDP)  
The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the  
functional and feature capabilities of serial flash devices in a standard set of internal parameter tables. These  
parameter tables can be interrogated by host system software to enable adjustments needed to accommodate  
divergent features from multiple vendors. The concept is similar to the one found in the Introduction of JEDEC  
Standard, JESD68 on CFI.  
The sequence of issuing RDSFDP instruction is CS# goes low→send RDSFDP instruction (5Ah)→send 3 address  
bytes on SI pin→send 1 dummy byte on SI pin→read SFDP code on SO→to end RDSFDP operation can use CS#  
to high at any time during data out.  
SFDP is a standard of JEDEC. JESD216. v1.0.

Note 1: h/b is hexadecimal or binary.  
Note 2: (x-y-z) means I/O mode nomenclature used to indicate the number of active pins used for the opcode (x),  
address (y), and data (z). At the present time, the only valid Read SFDP instruction modes are: (1-1-1), (2-2-2),  
and (4-4-4)  
Note 3: Wait States is required dummy clock cycles after the address bits or optional mode bits.  
Note 4: Mode Bits is optional control bits that follow the address bits. These bits are driven by the system controller  
if they are specified. (eg,read performance enhance toggling bits)  
Note 5: 4KB=2^0Ch, 32KB=2^0Fh, 64KB=2^10h  
Note 6: 0xFFh means all data is blank ("1b").

10. POWER-ON STATE  
The device is at the following states after 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 until the VCC reaches the following levels  
- 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), quad page program (4PP),  
sector erase (SE), block erase 32KB (BE32K), block erase (BE), chip erase (CE), WRSCUR and write status regis-  
ter (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 "Figure 36. Power-up Timing" .  
Note:  
- To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommend-  
ed. (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 this stage if a write, program, erase cycle is in progress.

13. OPERATING CONDITIONS  
At Device Power-Up and Power-Down  
AC timing illustrated in "Figure 37. AC Timing at Device Power-Up" and "Figure 38. Power-Down Sequence" are  
for the supply voltages and the control signals at device power-up and power-down. If the timing in the figures is ig-  
nored, the device will not operate correctly.  
During power-up and power-down, CS# needs to follow the voltage applied on VCC to keep the device not to be  
selected. The CS# can be driven low when VCC reach Vcc(min.) and wait a period of tVSL.
