MX25L12833F
2. GENERAL DESCRIPTION
MX25L12833F is 128Mb bits Serial NOR Flash memory, which is configured as 16,777,216 x 8 internally. When it is
in two or four I/O mode, the structure becomes 67,108,864 bits x 2 or 33,554,432 bits x 4. MX25L12833F 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# and RESET# pin (of the 8-pin packages) become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.
The MX25L12833F 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.
When the device is not in operation and CS# is high, it will remain in standby mode.
The MX25L12833F 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.
• 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.
• 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), and softreset command.
• 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 and T/B) 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 bit.
- In four I/O and QPI 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 second 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 12. Security Register Definition" for security
register bit definition and "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, this device becomes standby mode and keeps the standby
mode until next CS# falling edge. In standby mode, SO pin of this device should be High-Z.
3. When correct command is inputted to this device, this device 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 1. Serial Modes Supported".
5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, 2READ, DREAD, 4READ, QREAD,
RDSFDP, RES, REMS, QPIID, RDDPB, RDSPB, RDLR, RDCR 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, WPSEL, GBLK, GBULK,
SUSPEND, RESUME, NOP, RSTEN, RST, EQIO, RSTQIO 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.

8-1. Quad Peripheral Interface (QPI) Read Mode
QPI protocol enables user to take full advantage of Quad I/O Serial NOR Flash by providing the Quad I/O interface
in command cycles, address cycles and as well as data output cycles.
Enable QPI mode
By issuing EQIO command (35h), the QPI mode is enabled. After QPI mode has been enabled, the device enter
quad mode (4-4-4) without QE bit status changed.

Reset QPI (RSTQIO)
To reset the QPI mode, the RSTQIO (F5h) command is required. After the RSTQIO command is issued, the device
returns from QPI mode (4 I/O interface in command cycles) to SPI mode (1 I/O interface in command cycles).
Note:
For EQIO and RSTQIO commands, CS# high width has to follow "From Write/Erase/Program to Read Status
Register spec" tSHSL (as defined in "Table 18. AC CHARACTERISTICS") for next instruction.

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.

9-5. 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 tRES1, and Chip Select (CS#) must remain High for at least tRES1(max), as specified in "Table 18. AC CHARACTERISTICS". 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. Reset# pin goes low will release the Flash
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 6. 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.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care
when during SPI mode.
The RES instruction is ended by CS# goes high after the ID been read out at least once. The ID outputs repeatedly if continuously send the additional clock cycles on SCLK while CS# is at low. If the device was not previously
in Deep Power-down mode, the device transition to standby mode is immediate. If the device was previously in
Deep Power-down mode, there's a delay of tRES2 to transit to standby mode, and CS# must remain to high at least
tRES2(max). Once in the standby mode, the device waits to be selected, so it can be receive, decode, and execute
instruction.

9-6. 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.

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 32KB (BE32K), Block Erase (BE) 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 unprotected.
QE bit. The Quad Enable (QE) bit is a non-volatile bit with a factory default of “0”. When QE is “0”, Quad mode
commands are ignored; pins WP#/SIO2, DNU/SIO3 and the RESET#/SIO3 of 8-pin package function as WP#, DNU
pin and RESET#, respectively. When QE is “1”, Quad mode is enabled and Quad mode commands are supported
along with Single and Dual mode commands. Pins WP#/SIO2, DNU/SIO3 and the RESET#/SIO3 of 8-pin package
function as SIO2 and SIO3, respectively, and their alternate pin functions are disabled. Enabling Quad mode also
disables the HPM feature and the RESET feature of 8-pin package.
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.
ODS bit
The output driver strength (ODS2, ODS1, ODS0) bits are volatile bits, which indicate the output driver level (as
defined in Output Driver Strength Table) of the device. The Output Driver Strength is defaulted as 30 Ohms when
delivered from factory. To write the ODS bits requires the Write Status Register (WRSR) instruction to be executed.
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 bits requires the Write Status Register (WRSR) instruction to be executed.

9-10. 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 or 16 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 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, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1,
BP0 and T/B bit, 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 and T/B bit, 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 T/B bit 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 and T/B bit.
If the system enter QPI or set QE=1, the feature of HPM will be disabled.

9-11. 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.

9-12. 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.
Read on SPI Mode The sequence of issuing FAST_READ instruction is: CS# goes low→ sending FAST_READ
instruction code→ 3-byte address on SI→ 8 dummy cycles (default)→ data out on SO→ to end FAST_READ operation can use CS# to high at any time during data out.
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, FAST_READ instruction is rejected without any impact on the Program/Erase/Write Status Register current cycle.

9-13. Dual Output 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
SIO0→ 8 dummy cycles (default) on SIO0→ 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 impact

9-17. Burst Read
The Burst Read feature allows applications to fill a cache line with a fixed length of data without using multiple read
commands. Burst Read is disabled by default at power-up or reset. Burst Read is enabled by setting the Burst
Length. When the Burst Length is set, reads will wrap on the selected boundary (8/16/32/64-bytes) containing the
initial target address. For example if an 8-byte Wrap Depth is selected, reads will wrap on the 8-byte-page-aligned
boundary containing the initial read address.
To set the Burst Length, drive CS# low → send SET BURST LENGTH instruction code → send WRAP CODE →
drive CS# high. Refer to the table below for valid 8-bit Wrap Codes and their corresponding Wrap Depth.

Once Burst Read is enabled, it will remain enabled until the device is power-cycled or reset. The SPI and QPI mode
4READ read commands support the wrap around feature after Burst Read is enabled. To change the wrap depth,
resend the Burst Read instruction with the appropriate Wrap Code. To disable Burst Read, send the Burst Read
instruction with Wrap Code 1xh. QPI and SPI “EBh” support wrap around feature after wrap around is enabled. Both
SPI (8 clocks) and QPI (2 clocks) command cycle can be accepted by this instruction. The SIO[3:1] are don't care

9-18. Performance Enhance Mode
The device could waive the command cycle bits if the two cycle bits after address cycle toggles.
Performance enhance mode is supported in both SPI and QPI mode.
In QPI mode, “EBh” and SPI “EBh” commands support enhance mode. The performance enhance mode is not
supported in dual I/O mode.
To enter 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 skip the next 4READ instruction. To leave enhance mode, P[7:4] is no longer
toggling with P[3:0]; likewise P[7:0]=FFh, 00h, AAh or 55h along with CS# is afterwards raised and then lowered.
Issuing ”FFh” data cycle can also exit enhance mode. The system then will leave performance enhance mode and
return to normal operation.
After entering enhance mode, following CS# go high, the device will stay in the read mode and treat CS# go low of
the first clock as address instead of command cycle.
This sequence of issuing 4READ instruction is especially useful in random access: CS# goes low→send 4READ
instruction→3-bytes address interleave on SIO3, SIO2, SIO1 & SIO0 →performance enhance toggling bit P[7:0]→
4 dummy cycles (Default) →data out until CS# goes high → CS# goes low (the following 4READ instruction is
ignored) → 3-bytes random access address.
To conduct the Performance Enhance Mode Reset operation in SPI mode, FFh data cycle, 8 clocks, should be issued in 1I/O sequence. In QPI Mode, FFFFFFFFh data cycle, 8 clocks, in 4I/O should be issued.
If the system controller is being Reset during operation, the flash device will return to the standard SPI operation.

9-19. 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 (please refer to "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 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.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care
when during SPI mode.
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 1 during the tSE
timing, and clears when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the
Block is protected by BP bits (WPSEL=0; Block Lock (BP) protection mode) or SPB/DPB (WPSEL=1; Individual
Sector protection mode), the Sector Erase (SE) instruction will not be executed on the block.

9-23. Page Program (PP)
The Page Program (PP) instruction is for programming memory bits to "0". One to 256 bytes can be sent to the device to be programmed. A Write Enable (WREN) instruction must be executed to set the Write Enable Latch (WEL)
bit before sending the Page Program (PP). If more than 256 data bytes are sent to the device, only the last 256
data bytes will be accepted and the previous data bytes will be disregarded. The Page Program instruction requires
that all the data bytes fall within the same 256-byte page. The low order address byte A[7:0] specifies the starting
address within the selected page. Bytes that will cross a page boundary will wrap to the beginning of the selected
page. The device can accept (256 minus A[7:0]) data bytes without wrapping. If 256 data bytes are going to be programmed, A[7:0] should be set to 0.
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 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 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
Block is protected by BP bits (WPSEL=0; Block Lock (BP) protection mode) or SPB/DPB (WPSEL=1; Individual
Sector protection mode) the Page Program (PP) instruction will not be executed.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care

9-24. 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 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 application.
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.
If the page is protected by BP bits (WPSEL=0; Block Lock (BP) protection mode) or SPB/DPB (WPSEL=1; Individual Sector protection mode), the Quad Page Program (4PP) instruction will not be executed.

9-25. Deep Power-down (DP)
The Deep Power-down (DP) instruction places the device into a minimum power consumption state, Deep Powerdown 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 (after exactly eighth bits of the instruction code have been latched-in); otherwise the
instruction will not be executed. Both SPI (8 clocks) and QPI (2 clocks) command cycle can be accepted by this instruction. 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 before the current reduces from ISB1 to ISB2. Once in Deep Power-down mode, all instructions will be
ignored except Release from Deep Power-down (RDP).
The device exits Deep Power-down mode and returns to Stand-by mode if it receives a Release from Deep Powerdown (RDP) instruction, power-cycle, or reset.

Security Register
The definition of the Security Register bits is as below:
Write Protection Selection bit. Please reference to "9-30. Write Protection Selection (WPSEL)".
Erase Fail bit. The Erase Fail bit shows the status of last Erase operation. The bit will be set to "1" if the erase
operation failed or the erase region was protected. It will be automatically cleared to "0" if the next erase operation
succeeds. Please note that it will not interrupt or stop any operation in the flash memory.
Program Fail bit. The Program Fail bit shows the status of the last Program operation. The bit will be set to "1" if
the program operation failed or the program region was protected. It will be automatically cleared to "0" if the next
program operation succeeds. Please note that it will not interrupt or stop any operation in the flash memory.
Erase Suspend 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.
Program Suspend 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.
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 1st 4K-bit Secured
OTP area cannot be updated any more. While it is in 8K-bit secured OTP mode, main array access is not allowed.
Secured OTP Indicator bit. The Secured OTP indicator bit shows the 2nd 4K-bit Secured OTP area is locked by
factory or not. When it is "0", it indicates non-factory lock; "1" indicates factory-lock.

9-30. Write Protection Selection (WPSEL)
There are two write protection methods provided on this device, (1) Block Protection (BP) mode or (2) Individual
Sector Protection mode. The protection modes are mutually exclusive. The WPSEL bit selects which protection
mode is enabled. If WPSEL=0 (factory default), BP mode is enabled and Individual Sector Protection mode is disabled. If WPSEL=1, Individual Sector Protection mode is enabled and BP mode is disabled. The WPSEL command
is used to set WPSEL=1. A WREN command must be executed to set the WEL bit before sending the WPSEL command. Please note that the WPSEL bit is an OTP bit. Once WPSEL is set to “1”, it cannot be programmed back to “0”.
When WPSEL = 0: Block Lock (BP) protection mode,
The memory array is write protected by the BP3-BP0 bits.
When WPSEL =1: Individual Sector protection mode,
Blocks are individually protected by their own SPB or DPB. On power-up, all blocks are write protected by the Dynamic Protection Bits (DPB) by default. The Individual Sector Protection instructions WRLR, RDLR, WRSPB, ESSPB, WRDPB, RDDPB, GBLK, and GBULK are activated. The BP3-BP0 bits of the Status Register are disabled
and have no effect. Hardware protection is performed by driving WP#=0. Once WP#=0 all blocks and sectors are
write protected regardless of the state of each SPB or DPB.
The sequence of issuing WPSEL instruction is: CS# goes low → send WPSEL instruction to enable the Individual
Sector Protect mode → CS# goes high.

9-31. Advanced Sector Protection
Advanced Sector Protection can protect individual 4KB sectors in the bottom and top 64KB of memory and protect
individual 64KB blocks in the rest of memory.
There is one non-volatile Solid Protection Bit (SPB) and one volatile Dynamic Protection Bit (DPB) assigned to each
4KB sector at the bottom and top 64KB of memory and to each 64KB block in the rest of memory. A sector or block
is write-protected from programming or erasing when its associated SPB or DPB is set to “1”.
The figure below helps describing an overview of these methods. The device is default to the Solid mode when
shipped from factory. The detail algorithm of advanced sector protection is shown as follows:
Solid Protection mode permits the SPB bits to be modified after power-on or a reset. The figure below is an
overview of Advanced Sector Protection.

9-31-1. Lock Register
The Lock Register is a 16-bit one-time programmable register. Lock Register bit [6] is SPB Lock Down Bit (SPBLKDN)
which is an unique bit assigned to control all SPB bit status.
When SPBLKDN is 1, SPB can be changed. When it is locked as 0, all SPB can not be changed anymore, and
SPBLKDN bit itself can not be altered anymore, either.
The Lock Register is programmed using the WRLR (Write Lock Register) command. A WREN command must be
executed to set the WEL bit before sending the WRLR command.

9-31-2. Solid Protection Bits
The Solid Protection Bits (SPBs) are nonvolatile bits for enabling or disabling write-protection to sectors and blocks.
The SPB bits have the same endurance as the Flash memory. An SPB is assigned to each 4KB sector in the bottom
and top 64KB of memory and to each 64KB block in the remaining memory. The factory default state of the SPB bits
is “0”, which has the sector/block write-protection disabled.
When an SPB is set to “1”, the associated sector or block is write-protected. Program and erase operations on the
sector or block will be inhibited. SPBs can be individually set to “1” by the WRSPB command. However, the SPBs
cannot be individually cleared to “0”. Issuing the ESSPB command clears all SPBs to “0”. A WREN command must
be executed to set the WEL bit before sending the WRSPB or ESSPB command.
The RDSPB command reads the status of the SPB of a sector or block. The RDSPB command returns 00h if the
SPB is “0”, indicating write-protection is disabled. The RDSPB command returns FFh if the SPB is “1”, indicating
write-protection is enabled.
Note: If SPBLKDN=0, commands to set or clear the SPB bits will be ignored.

9-31-3. Dynamic Protection Bits
The Dynamic Protection Bits (DPBs) are volatile bits for quickly and easily enabling or disabling write-protection
to sectors and blocks. A DPB is assigned to each 4KB sector in the bottom and top 64KB of memory and to each
64KB block in the rest of the memory. The DBPs can enable write-protection on a sector or block regardless of the
state of the corresponding SPB. However, the DPB bits can only unprotect sectors or blocks whose SPB bits are “0”
(unprotected).
When a DPB is “1”, the associated sector or block will be write-protected, preventing any program or erase
operation on the sector or block. All DPBs default to “1” after power-on or reset. When a DPB is cleared to “0”, the
associated sector or block will be unprotected if the corresponding SPB is also “0”.
DPB bits can be individually set to “1” or “0” by the WRDPB command. The DBP bits can also be globally cleared to
“0” with the GBULK command or globally set to “1” with the GBLK command. A WREN command must be executed
to set the WEL bit before sending the WRDPB, GBULK, or GBLK command.
The RDDPB command reads the status of the DPB of a sector or block. The RDDPB command returns 00h if the
DPB is “0”, indicating write-protection is disabled. The RDDPB command returns FFh if the DPB is “1”, indicating
write-protection is enabled.

The device allow the interruption of Sector-Erase, Block-Erase or Page-Program operations and conduct other
operations.
After issue suspend command, the system can determine if the device has entered the Erase-Suspended mode
through Bit2 (PSB) and Bit3 (ESB) of security register. (please refer to "Table 12. Security Register Definition")
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care
when during SPI mode.
9-33. Erase Suspend
Erase suspend allow the interruption of all erase operations. After the device has entered Erase-Suspended mode,
the system can read any sector(s) or Block(s) except those being erased by the suspended erase operation.
Reading the sector or Block being erase suspended is invalid.
After erase suspend, WEL bit will be clear, only read related, resume and reset command can be accepted. (including:
03h, 0Bh, 3Bh, 6Bh, BBh, EBh, 5Ah, C0h, 06h, 04h, 2Bh, 9Fh, AFh, 05h, ABh, 90h, B1h, C1h, B0h, 30h, 66h, 99h,
00h, 35h, F5h, 15h, 2Dh, E2h, E0h)
If the system issues an Erase Suspend command after the sector erase operation has already begun, the device
will not enter Erase-Suspended mode until tESL time has elapsed.
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.
9-34. Program Suspend
Program suspend allows the interruption of all program operations. After the device has entered ProgramSuspended mode, the system can read any sector(s) or Block(s) except those being programmed by the suspended
program operation. Reading the sector or Block being program suspended is invalid.
After program suspend, WEL bit will be cleared, only read related, resume and reset command can be accepted.
(including: 03h, 0Bh, 3Bh, 6Bh, BBh, EBh, 5Ah, C0h, 06h, 04h, 2Bh, 9Fh, AFh, 05h, ABh, 90h, B1h, C1h, B0h, 30h,

9-35. Write-Resume
The Write operation is being resumed when Write-Resume instruction issued. ESB or PSB (suspend status bit) in
Status register will be changed back to “0”.
The operation of Write-Resume is as follows: CS# drives low → send write resume command cycle (30H) → drive
CS# high. By polling Busy Bit in status register, the internal write operation status could be checked to be completed
or not. The user may also wait the time lag of tSE, tBE, tPP for Sector-erase, Block-erase or Page-programming.
WREN (command "06") is not required to issue before resume. Resume to another suspend operation requires
latency time of 1ms.
Please note that, if "performance enhance mode" is executed during suspend operation, the device can not
be resumed. To restart the write command, disable the "performance enhance mode" is required. After the
"performance enhance mode" is disabled, the write-resume command is effective.
9-36. No Operation (NOP)
The “No Operation” command is only able to terminate the Reset Enable (RSTEN) command and will not affect any
other command.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care
during SPI mode.
9-37. Software Reset (Reset-Enable (RSTEN) and Reset (RST))
The Software Reset operation combines two instructions: Reset-Enable (RSTEN) command following a 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.
Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care
when during SPI mode.
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. For details, please refer to "Table 14. Reset Timing(Other Operation)" for tREADY2.

9-38. 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 JEDEC Standard, JESD216B.
For SFDP register values detail, please contact local Macronix sales channel for Application Note.

10. 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.
- 3-byte address mode
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.

11. 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, if the VCC does not reach the VCC minimum level, the correct operation is not
guaranteed. The read, write, erase, and program command should be sent after the below time delay:
- tVSL after VCC reached VCC minimum level
Please refer to the "Figure 77. 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.

13. OPERATING CONDITIONS
At Device Power-Up and Power-Down
AC timing illustrated in "Figure 75. AC Timing at Device Power-Up" and "Figure 76. 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.
