2. GENERAL DESCRIPTION
MX25L3233F is 32Mb bits Serial Flash memory, which is configured as 4,194,304 x 8 internally. When it is in
four I/O mode, the structure becomes 8,388,608 bits x 4. When it is in two I/O mode, the structure becomes
16,777,216 bits x 2. MX25L3233F 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.
MX25L3233F, MXSMIO® (Serial Multi I/O) flash memory, provides sequential read operation on the whole chip
and multi-I/O features.
When it is in quad I/O 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 Input/Output.
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/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.
When the device is not in operation and CS# is high, it is put in standby mode.
The MX25L3233F 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
power-up 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).
I. Block lock protection
- The Software Protected Mode (SPM) uses (TB, BP3, 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 1. Protected Area Sizes", the
protected areas are more flexible which may protect various areas by setting value of TB, BP0-BP3 bits.
- The Hardware Protected Mode (HPM) uses WP#/SIO2 to protect the (BP3, BP2, BP1, BP0, TB) bits and
SRWD bit.

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. For standard single data rate serial mode, 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 (for Normal Serial mode)".
5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, RDSFDP, 4READ, QREAD,
2READ, DREAD, RDCR, RES, and 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, BE, BE32K, CE, PP, 4PP, Suspend, Resume, NOP, RSTEN, RST, ENSO, EXSO, 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 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.

Write Enable (WREN)
The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP,
4PP, SE, BE, BE32K, CE, and WRSR which are intended to change the device content, should be set every time
after the WREN instruction setting the WEL bit.
The sequence of issuing WREN instruction is: CS# goes low→ sending WREN instruction code→ CS# goes
high.

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 of "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 use CS# to high at any time during data out.
While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the
cycle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby
stage.

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, a volatile bit, indicates whether the device is set to internal write enable latch. When WEL bit sets to "1", which means the internal write enable latch is set, the device can accept
program/erase/write status register instruction. When WEL bit sets to 0, which means no internal write enable
latch; the device will not accept program/erase/write status register instruction. The program/erase command will
be ignored and will reset WEL bit if it is applied 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.
BP3, BP2, BP1, BP0 bits. The Block Protect (BP3, BP2, BP1, BP0) bits, non-volatile bits, indicate the protected area (as defined in "Table 1. 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) and Chip Erase (CE) instructions (only if all
Block Protect bits 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#
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 feature of HPM will be disabled.
SRWD bit. The Status Register Write Disable (SRWD) bit, non-volatile bit, default value is "0". SRWD 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 ODS bit are volatile bits, which indicate the output driver level of the device. The
Output Driver Strength is defaulted=1 when delivered from factory. To write the ODS bit requires the Write Status
Register (WRSR) instruction to be executed.
TB bit
The Top/Bottom (TB) bit is a 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.

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 1. 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 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 checked out during the Write Status Register cycle is in progress. The
WIP sets 1 during the tW timing, and sets 0 when Write Status Register Cycle is completed, and the Write Enable Latch (WEL) bit is reset.

As the table above showing, the summary of the Software Protected Mode (SPM) and Hardware Protected Mode
(HPM):
Software Protected Mode (SPM):
- When SRWD bit=0, no matter WP#/SIO2 is low or high, the WREN instruction may set the WEL bit and can
change the values of SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1,
BP0, is at software protected mode (SPM).
- When SRWD bit=1 and WP#/SIO2 is high, the WREN instruction may set the WEL bit can change the values
of SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1, BP0, is at software
protected mode (SPM)
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, TB 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, TB.
If the system goes into four I/O mode, the feature of HPM will be disabled.

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.

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 11. 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
impact on the Program/Erase/Write Status Register current cycle.

Dual Read Mode (DREAD)
The DREAD instruction enable double throughput of Serial Flash in read mode. The address is latched on rising edge of SCLK, and data of every two bits (interleave on 2 I/O pins) shift out on the falling edge of SCLK at
a maximum frequency fT. The first address byte can be at any location. The address is automatically increased
to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single
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 SO1 & SO0 → 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 on the Program/Erase/Write Status Register current cycle.

10-10. 2 x I/O Read Mode (2READ)
The 2READ instruction enables Double Transfer Rate of Serial Flash in read mode. The address is latched on
rising edge of SCLK, and data of every two bits (interleave on 2 I/O pins) shift out on the falling edge of SCLK at
a maximum frequency fT. The first address byte can be at any location. The address is automatically increased
to the next higher address after each byte data is shifted out, so the whole memory can be read out at a single
2READ instruction. The address counter rolls over to 0 when the highest address has been reached. Once writing 2READ instruction, the following address/dummy/data out will perform as 2-bit instead of previous 1-bit.
The sequence of issuing 2READ instruction is: CS# goes low→ sending 2READ instruction→ 24-bit address interleave on SIO1 & SIO0→ 4 dummy cycles(default) on SIO1 & SIO0→ data out interleave on SIO1 & SIO0→ to
end 2READ operation can use CS# to high at any time during data out.
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.

10-11. Quad Read Mode (QREAD)
The QREAD instruction enable quad throughput of Serial Flash in read mode. 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
QREAD instruction. The address counter rolls over to 0 when the highest address has been reached. Once writing QREAD instruction, the following data out will perform as 4-bit instead of previous 1-bit.
The sequence of issuing QREAD instruction is: CS# goes low→ sending QREAD instruction → 3-byte address
on SI → 8-bit dummy cycle → data out interleave on SIO3, SIO2, SIO1 & SIO0→ to end QREAD operation can
use CS# to high at any time during data out.
While Program/Erase/Write Status Register cycle is in progress, QREAD instruction is rejected without any impact on the Program/Erase/Write Status Register current cycle.

10-12. 4 x I/O Read Mode (4READ)
The 4READ instruction enables quad throughput of Serial 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 (default) →data out interleave on SIO3, SIO2, SIO1 &

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 until CS# goes high → CS# goes low (reduce 4READ instruction) →
24-bit random access address (Please refer to "Figure 16. 4 x I/O Read enhance performance Mode Sequence
(Command EB) (SPI Mode)" ).
In the performance-enhancing mode (Notes of "Figure 16. 4 x I/O Read enhance performance Mode Sequence
(Command EB) (SPI 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. These commands will reset the performance enhance mode. And afterwards CS# is raised and then lowered, the system then will 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.

10-13. Performance Enhance Mode
The device could waive the command cycle bits if the two cycle bits after address cycle toggles. (Please note
"Figure 16. 4 x I/O Read enhance performance Mode Sequence (Command EB) (SPI Mode)")
Performance enhance mode is supported for 4READ mode.
“EBh” commands support enhance mode.
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.
To exit enhance mode, a new fast read command whose first two dummy cycles is not toggle then exit. Or issue
”FFh” data cycles to exit enhance mode.

The wrap around unit is defined within the wrap-around depth specified region. For example, if it is set to 32byte wrap depth, then address above A5 will be kept, it will read wrap around within A[21:A5] specified page. To
exit wrap around, it is required to issue another “C0h” or “77h” command in which data=‘1xh”. Otherwise, wrap
around status will be retained until power down or reset command. To change wrap around depth, it is requried
to issue another “C0h” or “77h” command in which data=“0xh”. “EBh” support wrap around feature after wrap
around enable. The Device ID default without Burst read.

10-16. Sector Erase (SE)
The Sector Erase (SE) instruction is for erasing the data of the chosen sector to be "1". The instruction is used
for any 4K-byte sector. A Write Enable (WREN) instruction must execute to set the Write Enable Latch (WEL)
bit before sending the Sector Erase (SE). Any address of the sector (see "Table 3. 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 has been latched-in); otherwise, the instruction will be rejected and not executed.
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 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 BP3~0, the array data will be protected (no change) and the WEL bit still be reset.

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 eight 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 requested 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 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 page is protected by BP3~0, the array data will be protected (no change) and the WEL bit will still be reset.

10-21. 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, which can raise programmer performance and the effectiveness of application of lower clock
less than 133MHz. For system with faster clock, the Quad page program cannot provide more performance,
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
133MHz 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.
If the page is protected by BP3~0, the array data will be protected (no change) and the WEL bit will still be reset.

10-22. Deep Power-down (DP)
The Deep Power-down (DP) instruction is for setting the device to minimum power consumption (the standby
current is reduced from ISB1 to ISB2). The Deep Power-down mode requires the Deep Power-down (DP) instruction to enter, during the Deep Power-down mode, the device is not active and all Write/Program/Erase instructions are ignored. When CS# goes high, the device is in standby mode not deep power-down mode.
The sequence of issuing DP instruction is: CS# goes low→ sending DP instruction code→ CS# goes high.
The SIO[3:1] are don't care when during this mode.
Once the DP instruction is set, all instructions will be ignored except the Release from Deep Power-down mode (RDP)
and Read Electronic Signature (RES) instruction. (those instructions allow the ID being reading out). When
Power-down, the deep power-down mode automatically stops, and when power-up, the device automatically is
in standby mode. For RDP instruction the CS# must go high exactly at the byte boundary (the latest eighth bit of
instruction code has been latched-in); otherwise, the instruction will not be executed. As soon as Chip Select (CS#)
goes high, a delay of tDP is required before entering the Deep Power-down mode and reducing the current to
ISB2.

10-23. 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 standby Power mode. If the device was not previously in
the Deep Power-down mode, the transition to the standby Power mode is immediate. If the device was previously
in the Deep Power-down mode, though, the transition to the standby Power mode is delayed by tRES2, and Chip
Select (CS#) must remain High for at least tRES2(max), as specified in "Table 15. AC Characteristics". Once in
the standby mode, the device waits to be selected, so that it can receive, decode and execute instructions.
RES instruction is for reading out the old style of 8-bit Electronic Signature, whose values are shown as "Table 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 cycles; there's no effect on the current
program/erase/write cycles in progress.
The SIO[3:1] are don't care when during this 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 receive, decode, and
execute instruction.
The RDP instruction is for releasing from Deep Power-down Mode.

10-24. Read Electronic Manufacturer ID & Device ID (REMS)
The REMS instruction is an alternative to the Release from Power-down/Device ID instruction that provides both
the JEDEC assigned manufacturer ID and the specific device ID.
The REMS instruction is very similar to the Release from Power-down/Device ID instruction. The instruction is
initiated by driving the CS# pin low and shift the instruction code "90h" followed by two dummy bytes and one
bytes address (A7~A0). After which, the Manufacturer ID for Macronix (C2h) and the Device ID are shifted out
on the falling edge of SCLK with most significant bit (MSB) first. The Device ID values are listed in "Table 6. ID
Definitions". If the one-byte address is initially set to 01h, then the device ID will be read first and then followed
by the Manufacturer ID. The Manufacturer and Device IDs can be read continuously, alternating from one to the
other. The instruction is completed by driving CS# high.

10-25. Enter Secured OTP (ENSO)
The ENSO instruction is for entering the additional 4K-bit Secured OTP mode. While the device is in 4K-bit Secured OTP mode, 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.
The SIO[3:1] are don't care.
Please note that WRSR/WRSCUR/CE/BE/SE/BE32K commands are not acceptable during the access of secure
OTP region, once Security OTP is locked down, only read related commands are valid.

The definition of the Security Register 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 customer lock-down purpose. However, once the bit is set to "1" (lock-down), the LDSO bit and the 4K-bit Secured
OTP area cannot be 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 Suspend and Erase Suspend
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 8. Readable Area of
Memory While a Program or Erase Operation is Suspended").

When the serial flash receives the Suspend instruction, there is a latency of tPSL or tESL ("Figure 33. Suspend
to Read 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 9. Acceptable Commands During Program/Erase Suspend after tPSL/tESL" (e.g. FAST READ). Refer to "Table 15. AC Characteristics" for tPSL and
tESL timings. "Table 10. 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.

Program Suspend
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 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 36. 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 34. Resume to Suspend Latency").
Please note that the Resume instruction will be ignored if the serial flash is in “Performance Enhance Mode”.
Make sure the serial flash is not in “Performance Enhance Mode” before issuing the Resume instruction.

10-31. No Operation (NOP)
The "No Operation" command is only able to terminate the Reset Enable (RSTEN) command and will not affect
any other command.
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.
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.

10-33. 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, JESD216.

Notes:
1: h/b is hexadecimal or binary.
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: (1-11), (2-2-2), and (4-4-4)
3: Wait States is required dummy clock cycles after the address bits or optional mode bits.
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)
5: 4KB=2^0Ch, 32KB=2^0Fh, 64KB=2^10h
6: All unused and undefined area data is blank FFh for SFDP Tables that are defined in Parameter

11. POWER-ON STATE
The device is at the following states after power-up:
- Standby 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.
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 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.
Note:
- To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommended. (generally around 0.1uF)

Notes:
1. tCH + tCL must be greater than or equal to 1/ fC.
2. The value guaranteed by characterization, not 100% tested in production.
3. Only applicable as a constraint for a WRSR instruction when SRWD is set at 1.
4. Latency time is required to complete Erase/Program Suspend operation until WIP bit is "0".
5. For tPRS, minimum timing must be observed before issuing the next program suspend command.
However, a period equal to or longer than the typical timing is required in order for the program operation
to make progress.
6. For tERS, minimum timing must be observed before issuing the next erase suspend command.
However, a period equal to or longer than the typical timing is required in order for the erase operation to
make progress.

At Device Power-Up and Power-Down
AC timing illustrated in "Figure 47. AC Timing at Device Power-Up" and "Figure 48. 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.
