2. GENERAL DESCRIPTION
MX25R8035F is 8Mb bits Serial NOR Flash memory, which is configured as 1,048,576 x 8 internally. When it is in
four I/O mode, the structure becomes 2,097,152 bits x 4 or 4,194,304 bits x 2.
MX25R8035F features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus
while it is in single I/O mode. 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 RESET#/HOLD# pin
become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25R8035F 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, or word basis. Erase command is executed on 4K-byte sector, 32K-byte block, or 64K-byte block, 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.
The MX25R8035F utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after
100,000 program and erase cycles.

6. DATA PROTECTION
During power transition, there may be some false system level signals which result in inadvertent erasure or
programming. 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
architecture of the device constrains that the memory contents can only be changed after specific command
sequences have completed successfully.
In the following, there are several features to protect the system from the accidental write cycles during VCC powerup and power-down or from system noise.
•
Power-on reset: to avoid sudden power switch by system power supply transition, the power-on reset 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
issuing other commands to change data.
•
Deep Power Down Mode: By entering deep power down mode, the flash device is under protected from writing
all commands except toggling the CS#. For more detail please see "10-24. Deep Power-down (DP)".
•
Advanced Security Features: there are some protection and security 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 protected area definition is shown as "Table 2. Protected Area Sizes", the protected areas are
more flexible which may protect various area by setting value of BP0-BP3 bits.
- The Hardware Protected Mode (HPM) use WP#/SIO2 to protect the (BP3, BP2, BP1, BP0) bits and Status
Register Write Protect (SRWD) bit. If the system goes into four I/O mode, the feature of HPM will be disabled.

II. Additional 8K-bit secured OTP for unique identifier: to provide 8K-bit One-Time Program area for setting
device unique serial number - Which may be set by factory or system maker.
The 8K-bit secured OTP area is composed of two rows of 4K-bit. Customer could lock the first 4K-bit OTP
area and factory could lock the other.
- Security register bit 0 indicates whether the 2nd 4K-bit is locked by factory or not.
- 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 "Table 8. Security Register Definition"
for security register bit definition and table of "Table 3. 8K-bit Secured OTP Definition" for address range
definition.
- To program 8K-bit secured OTP by entering secured OTP mode (with ENSO command), and going through
normal program procedure, and then exiting secured OTP mode by writing EXSO command.
Note: Once lock-down whatever by factory or customer, the corresponding secured area cannot be changed any
more. While in 8K-bit Secured OTP mode, array access is not allowed.

8. 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 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 shifts 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, RDCR, RDSCUR, READ, FAST_READ, DREAD, 2READ, 4READ,
QREAD, RDSFDP, RES, REMS, 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, DP, ENSO, EXSO, WRSCUR, SUSPEND, RESUME, NOP, RSTEN, RST, 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
neglected and will not affect the current operation of Write Status Register, Program, Erase.

9. 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 Serial 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).

During the HOLD operation, the Serial Data Output (SO) is high impedance when Hold# pin goes low and will keep
high impedance until Hold# pin goes high. The Serial Data Input (SI) is don't care if both Serial Clock (SCLK) and
Hold# pin goes low and will keep the state until SCLK goes low and Hold# pin goes high. 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.
Note: The HOLD feature is disabled during Quad I/O mode.

10-3. 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 and Device ID are listed as "Table 6. 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.
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.

10-5. Read Electronic Manufacturer ID & Device ID (REMS)
The REMS instruction returns both the JEDEC assigned manufacturer ID and the device ID. The Device ID values
are listed in "Table 6. ID Definitions".
The REMS instruction is initiated by driving the CS# pin low and sending the instruction code "90h" followed by two
dummy bytes and one address byte (A7~A0). After which the manufacturer ID for Macronix (C2h) and the device
ID are shifted out on the falling edge of SCLK with the most significant bit (MSB) first. If the address byte is 00h,
the manufacturer ID will be output first, followed by the device ID. If the address byte is 01h, then the device ID will
be output first, followed by the manufacturer ID. While CS# is low, the manufacturer and device IDs can be read
continuously, alternating from one to the other. The instruction is completed by driving CS# high.

10-6. ID Read
User can execute this ID Read instruction to identify the Device ID and Manufacturer ID. 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.
After the command cycle, the device will immediately output data on the falling edge of SCLK. The manufacturer ID,
memory type, and device ID data byte will be output continuously, until the CS# goes high.
While Program/Erase operation is in progress, it will not decode the RDID instruction, therefore there's no effect on

Status Register
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 is a volatile bit that is set to “1” by the WREN instruction. WEL needs to be
set to “1” before the device can accept program and erase instructions, otherwise the program and erase instructions
are ignored. WEL automatically clears to “0” when a program or erase operation completes. To ensure that both WIP
and WEL are “0” and the device is ready for the next program or erase operation, it is recommended that WIP be
confirmed to be “0” before checking that WEL is also “0”. If a program or erase instruction is applied to a protected
memory area, the instruction will be ignored and WEL will clear to “0”.
BP3, BP2, BP1, BP0 bits. The Block Protect (BP3, 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 (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/BE32K) and Chip Erase (CE) instructions (only if Block Protect bits (BP3:BP0) set to 0,
the CE instruction can be executed). The BP3, 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#,
RESET#/HOLD# are enable. While QE is "1", it performs Quad I/O mode and WP#, RESET#/HOLD# are disabled.
In the other word, if the system goes into four I/O mode (QE=1), the feature of HPM and RESET/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 (BP3, BP2, BP1, BP0) are read only. The
SRWD bit defaults to be "0".

Configuration Register
The Configuration Register is able to change the default status of Flash memory. Flash memory will be configured
after the CR bit is set.
TB bit
The Top/Bottom (TB) bit is a non-volatile OTP bit. The Top/Bottom (TB) bit is used to configure the Block Protect
area by BP bit (BP3, BP2, BP1, BP0), starting from TOP or Bottom of the memory array. The TB bit is defaulted as “0”,
which means Top area protect. When it is set as “1”, the protect area will change to Bottom area of the memory
device. To write the TB bit requires the Write Status Register (WRSR) instruction to be executed.
L/H switch bit
The Low Power / High Performance bit is a volatile bit. User can change the value of L/H switch bit to keep Ultra
Low Power mode or High Performance mode. Please check Ordering Information for the L/H Switch default
support.

10-8. Read Configuration Register (RDCR)
The RDCR instruction is for reading Configuration Register Bits. The Read Configuration Register can be read
at any time (even in program/erase/write configuration register condition). It is recommended to check the Write
in Progress (WIP) bit before sending a new instruction when a program, erase, or write configuration register
operation is in progress.
The sequence of issuing RDCR instruction is: CS# goes low→ sending RDCR instruction code→ Configuration
Register data out on SO.
The SIO[3:1] are don't care.

10-9. Write Status Register (WRSR)
The WRSR instruction is for changing the values of Status Register Bits and Configuration 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 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.
The CS# must go high exactly at the 8 bits, 16 bits or 24 bits data 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 checked 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. Please note that there is another parameter, "Write Status Register cycle time
for Mode Changing Switching (tWMS)", which is only for the self-timed of Mode Switching. For more detail please
check "Table 17. AC Characteristics".

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.
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.

10-10. 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.

10-11. 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.
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.

10-12. Dual Read Mode (DREAD)
The DREAD instruction enable double throughput of Serial NOR 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
DREAD instruction. The address counter rolls over to 0 when the highest address has been reached. Once
writing DREAD instruction, the following data out will perform as 2-bit instead of previous 1-bit.
The sequence of issuing DREAD instruction is: CS# goes low → sending DREAD instruction → 3-byte address
on SI → 8-bit dummy cycle → data out interleave on SIO1 & SIO0 → to end DREAD operation can use CS# to
high at any time during data out.
While Program/Erase/Write Status Register cycle is in progress, DREAD instruction is rejected without any

10-15. 4 x I/O Read Mode (4READ)
The 4READ instruction enable quad throughput of Serial NOR Flash in read mode. A Quad Enable (QE) bit of status
Register 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
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→2+4 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.
Another sequence of issuing 4READ instruction especially useful in random access is: CS# goes low→sending
4READ 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.
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];
likewise 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.
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.

10-18. 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 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.
The SIO[3:1] are "don't care".
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 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 sector is protected by BP3, BP2, BP1, BP0 bits, the Sector Erase (SE) instruction will not be executed on the
sector.

10-19. 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
Organization") 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 has 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.
The SIO[3:1] are don't care.
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 the 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 BP3~0, the array data will be protected (no change) and the WEL bit still be
reset.

10-20. 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 (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 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.
The SIO[3:1] are "don't care".
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 during the Block Erase cycle is in progress. The WIP sets 1 during the tBE
timing, and sets 0 when Block Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the block
is protected by BP3, BP2, BP1, BP0 bits, the Block Erase (BE) instruction will not be executed on the block.

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, 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.
The SIO[3:1] are "don't care".
The self-timed Chip Erase Cycle time (tCE) is initiated as soon as Chip Select (CS#) goes high. The Write in

10-22. 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
programs only the last 256 data bytes sent to the device. 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.
The CS# must be kept 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 checked 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.
The SIO[3:1] are "don't care".

10-23. 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 as address and data input, which can improve programmer performance and the effectiveness of application.
The 4PP operation frequency supports as fast as f4PP. 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.

10-24. Deep Power-down (DP)
The Deep Power-down (DP) instruction places the device into a minimum power consumption state, Deep Power
down mode, in which the quiescent current is reduced from ISB1 to ISB2.
The sequence of issuing DP instruction: CS# goes low→ send DP instruction code→ CS# goes high. The CS# must
go high at the byte boundary; otherwise the instruction will not be executed. SIO[3:1] are "don't care".
After CS# goes high there is a delay of tDP before the device transitions from Stand-by mode to Deep Power-down
mode and the current reduces from ISB1 to ISB2. Once in Deep Power-down mode, all instructions will be ignored.
CS# must not be pulsed low until the device has been in Deep Power-down mode for a minimum of tDPDD. The
device exits Deep Power-down mode and returns to Stand-by mode if CS# pulses low for tCRDP or if the device is
power-cycled or hardware reset. After CS# goes high, there is a delay of tRDP before the device transitions from
Deep Power-down mode back to Stand-by mode.

10-25. Enter Secured OTP (ENSO)
The ENSO instruction is for entering the additional 8K-bit secured OTP mode. While the device is in 8K-bit Secured
OTP mode, array access is not available. The additional 8K-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.
The SIO[3:1] are "don't care".
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.
10-26. Exit Secured OTP (EXSO)
The EXSO instruction is for exiting the additional 8K-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.
The SIO[3:1] are "don't care".
10-27. 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.
The SIO[3:1] are "don't care".
The definition of the Security Register bits is as below:
Secured OTP Indicator bit. The Secured OTP indicator bit shows the secured OTP area 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
customer lock-down purpose. However, once the bit is set to "1" (lock-down), the LDSO bit and the 1st 4K-bit
Secured OTP area cannot be updated any more.
Program Suspend Status bit. Program Suspend Bit (PSB) indicates the status of Program Suspend operation.
Users may use PSB to identify the state of flash memory. After the flash memory is suspended by Program Suspend
command, PSB is set to "1". PSB is cleared to "0" after program operation resumes.
Erase Suspend Status bit. Erase Suspend Bit (ESB) indicates the status of Erase Suspend operation. Users may
use ESB to identify the state of flash memory. After the flash memory is suspended by Erase Suspend command,
ESB is set to "1". ESB is cleared to "0" after erase operation resumes.

10-29. Program/Erase Suspend/Resume
The Suspend instruction interrupts a Page Program, Sector Erase, or Block Erase operation to allow access to
the memory array. After the program or erase operation has entered the suspended state, the memory array can
be read except for the page being programmed or the sector or block being erased ("Table 9. Readable Area of
Memory While a Program or Erase Operation is Suspended").

When the Serial NOR Flash receives the Suspend instruction, there is a latency of tPSL or tESL ("Figure 33.
Suspend to Read/Program Latency") before the Write Enable Latch (WEL) bit clears to “0” and the PSB or ESB sets
to “1”, after which the device is ready to accept one of the commands listed in "Table 10. Acceptable Commands
During Program/Erase Suspend after tPSL/tESL" (e.g. FAST READ). Refer to "Table 17. AC Characteristics" for
tPSL and tESL timings. "Table 11. Acceptable Commands During Suspend (tPSL/tESL not required)" lists the
commands for which the tPSL and tESL latencies do not apply. For example, RDSR, RDSCUR, RSTEN, and RST
can be issued at any time after the Suspend instruction.
Security Register bit 2 (PSB) and bit 3 (ESB) can be read to check the suspend status. The PSB (Program Suspend
Bit) sets to “1” when a program operation is suspended. The ESB (Erase Suspend Bit) sets to “1” when an erase
operation is suspended. The PSB or ESB clears to “0” when the program or erase operation is resumed.

10-29-1. Erase Suspend to Program
The “Erase Suspend to Program” feature allows Page Programming while an erase operation is suspended. Page
Programming is permitted in any unprotected memory except within the sector of a suspended Sector Erase
operation or within the block of a suspended Block Erase operation. The Write Enable (WREN) instruction must be
issued before any Page Program instruction.
A Page Program operation initiated within a suspended erase cannot itself be suspended and must be allowed to
finish before the suspended erase can be resumed. The Status Register can be polled to determine the status of
the Page Program operation. The WEL and WIP bits of the Status Register will remain “1” while the Page Program
operation is in progress and will both clear to “0” when the Page Program operation completes.

10-30. Program Resume and Erase Resume
The Resume instruction resumes a suspended Page Program, Sector Erase, or Block Erase operation. Before
issuing the Resume instruction to restart a suspended erase operation, make sure that there is no Page Program
operation in progress.
Immediately after the Serial NOR Flash receives the Resume instruction, the WEL and WIP bits are set to “1” and
the PSB or ESB is cleared to “0”. The program or erase operation will continue until finished ("Figure 34. Resume
to Read Latency") or until another Suspend instruction is received. A resume-to-suspend latency of tPRS or tERS
must be observed before issuing another Suspend instruction ("Figure 32. Resume to Suspend Latency").
Please note that the Resume instruction will be ignored if the Serial NOR Flash is in “Performance Enhance Mode”.
Make sure the Serial NOR Flash is not in “Performance Enhance Mode” before issuing the Resume instruction.

The "No Operation" command is only able to terminate the Reset Enable (RSTEN) command and will not affect any
other command.
The SIO[3:1] are don't care.
10-32. Software Reset (Reset-Enable (RSTEN) and Reset (RST))
The Software Reset operation combines two instructions: Reset-Enable (RSTEN) command and Reset (RST)
command. It returns the device to a standby mode. All the volatile bits and settings will be cleared then, which
makes the device return to the default status as power on.
To execute Reset command (RST), the Reset-Enable (RSTEN) command must be executed first to perform the
Reset operation. If there is any other command to interrupt after the Reset-Enable command, the Reset-Enable will
be invalid.
The SIO[3:1] are "don't care".
If the Reset command is executed during program or erase operation, the operation will be disabled, the data under
processing could be damaged or lost.
The reset time is different depending on the last operation. Longer latency time is required to recover from a
program operation than from other operations.

The flash device supports High Voltage Operation. This opeartion allows user can have better performance in
following Program/Erase operation.
To enable High Voltage Opeartion, WP#/SIO2 need to apply Vhv during whole operation. If the voltage can not
sustain in Vhv range, the Program/Erase opeation might be failed. CS# can only go low after tVSL1+tVhv +tVhv2
timing during High Voltage Operation. WP# can only start to go low after whole Erase/Program Operation has been
done.
To check the operation status, user may check the status of WIP bit.

10-34. 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 same as FAST_READ: 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 JEDEC Standard, JESD216B.
For SFDP register values detail, please contact local Macronix sales channel for Application Note.

11. RESET
Driving the RESET# pin low for a period of tRLRH or longer will reset the device. After reset cycle, the device is at
the following states:
- Standby mode
- All the volatile bits such as WEL/WIP/SRAM lock bit will return to the default status as power on.
If the device is under programming or erasing, driving the RESET# pin low will also terminate the operation and data
could be lost. During the resetting cycle, the SO data becomes high impedance and the current will be reduced to
minimum.

12. POWER-ON STATE
The device is at the following 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 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, 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:
- 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 46. 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 this stage if a write, program, erase cycle is in progress.

Notes:
1. tCH + tCL must be greater than or equal to 1/ Frequency.
2. Typical values given for TA=25°C. Not 100% tested.
3. Only applicable as a constraint for a WRSR instruction when SRWD is set at 1.
4. Program operation may be interrupted as often as system request. The minimum timing of tPRS must be
observed before issuing the next program suspend command. However, in order for an Program operation to
make progress, tPRS ≥ 100us must be included in resume-to-suspend loop(s). Not 100% tested.
5. Erase operation may be interrupted as often as system request. The minimum timing of tERS must be observed
before issuing the next erase suspend command. However, in order for an Erase operation to make progress,
tERS ≥ 200us must be included in resume-to-suspend loop(s). The details are described in Macronix application
notes. Not 100% tested.
6. Test condition is shown as "Figure 42. Input Test Waveforms and Measurement Level", "Figure 43. Output

At Device Power-Up and Power-Down
AC timing illustrated in "Figure 44. AC Timing at Device Power-Up" and "Figure 45. 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
ignored, 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.
