MX25L6465E
MX25L12865E
GENERAL DESCRIPTION
MX25L6465E is 67,108,864 bits serial Flash memory, which is configured as 8,388,608 x 8 internally. When it
is in two or four I/O mode, the structure becomes 33,554,432 bits x 2 or 16,777,216 bits x 4. MX25L12865E is
134,217,728 bits serial 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. The MX25L6465E/12865E features a se-
rial peripheral interface and software protocol allowing operation on a simple 4-wire bus. The four bus signals are a
clock input (SCLK), a serial data input (SI), a serial data output (SO), and a chip select (CS#). Serial access to the
device is enabled by CS# input.
MX25L6465E/12865E provides high performance read mode, which may latch address and data on both rising and
falling edge of clock. By using this high performance read mode, the data throughput may be doubling. Moreover,
the performance may reach direct code execution, the RAM size of the system may be reduced and further saving
system cost.
MX25L6465E/12865E, MXSMIOTM (Serial Multi I/O) flash memory, provides sequential read operation on whole
chip and multi-I/O features.
When it is in dual I/O 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 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. Parallel mode is also provided in this
device. It features 8 bit input/output for increasing throughputs. This feature is recommeded to be used for factory
production purpose.
After program/erase command is issued, auto program/ erase algorithms which program/ erase and verify the
specified page or sector/block locations will be executed. Program command is executed on byte basis, or page (256
bytes) basis, or word basis for Continuously Program mode, and erase command is executes on sector (4K-byte),
block (32K-byte/64K-byte), or whole chip basis.
To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read
command can be issued to detect completion status of a program or erase operation via WIP bit.
When the device is not in operation and CS# is high, it is put in standby mode and draws less than 100uA DC cur-
rent.
The MX25L6465E/12865E utilizes Macronix's proprietary memory cell, which reliably stores memory contents even
after 100,000 program and erase cycles.

DATA PROTECTION
MX25L6465E/12865E is designed to offer protection against accidental erasure or programming caused by spuri-
ous system level signals that may exist during power transition. During power up the device automatically resets
the state machine in the standby mode. In addition, with its control register architecture, alteration of the memory
contents only occurs after successful completion of specific command sequences. The device also incorporates
several features to prevent inadvertent write cycles resulting from VCC power-up and power-down transition or sys-
tem 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. The WEL bit will return to reset stage under following situation:
- Power-up
- Write Disable (WRDI) command completion
- Write Status Register (WRSR) command completion
- Page Program (PP, 4PP) command completion
- Continuously Program mode (CP) instruction completion
- Sector Erase (SE) command completion
- Block Erase (BE, BE32K) command completion
- Chip Erase (CE) command completion
- Single Block Lock/Unlock (SBLK/SBULK) instruction completion
- Gang Block Lock/Unlock (GBLK/GBULK) instruction completion
•
Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from
writing all commands except Release from Deep Power Down mode command (RDP) and Read Electronic Sig-
nature command (RES).

- The Software Protected Mode (SPM) uses (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 "Protected Area Sizes", the protected areas are
more flexible which may protect various area by setting value of BP0-BP3 bits. Please refer to table of "Protect-
ed Area Sizes".
- The Hardware Protected Mode (HPM) use WP#/SIO2 to protect the (BP3, BP2, BP1, BP0) bits and SRWD bit.
If the system goes into four I/O mode, the feature of HPM will be disabled.
- MX25L6465E/12865E provide individual block (or sector) write protect & unprotect. User may enter the mode
with WPSEL command and conduct individual block (or sector) write protect with SBLK instruction, or SBULK
for individual block (or sector) unprotect. Under the mode, user may conduct whole chip (all blocks) protect with
GBLK instruction and unlock the whole chip with GBULK instruction.

DEVICE OPERATION
1. Before a command is issued, status register should be checked to ensure device is ready for the intended op-
eration.
2. When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode
until next CS# falling edge. In standby mode, SO pin of this LSI should be High-Z.
3. When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until
next CS# rising edge.
4. For standard single data rate serial mode, 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 1-1.
For high performance (Double Transfer Rate Read serial mode), data is latched on both rising and falling edge
of clock and data shifts out on both rising and falling edge of clock as Figure 1-2.
5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, RDSFDP, 2READ, 4READ, FAST-
DTRD, 2DTRD, 4DTRD, RDBLOCK, RES, REMS, REMS2, REMS4, and REMS4D the shifted-in instruction se-
quence 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, HPM, CE, PP, CP, 4PP, RDP, DP, WPSEL, SBLK,
SBULK, GBLK, GBULK, ENSO, EXSO, WRSCUR, ENPLM, EXPLM, ESRY, DSRY and CLSR the CS# must go
high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
6. During the progress of Write Status Register, Program, Erase operation, to access the memory array is neglect-
ed and not affect the current operation of Write Status Register, Program, Erase.

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 Se-
rial Clock(SCLK) signal is being low (if Serial Clock signal is not being low, HOLD operation will not end until Serial
Clock being low), see Figure 2.

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

MX25L12865E
(1) Write Enable (WREN)
The Write Enable (WREN) instruction is for setting Write Enable Latch (WEL) bit. For those instructions like PP, 4PP,
CP, SE, BE, BE32K, CE, WRSR, SBLK, SBULK, GBLK and GBULK, which are intended to change the device con-
tent, should be set every time after the WREN instruction setting the WEL bit.
The sequence of issuing WREN instruction is: CS# goes low→ sending WREN instruction code→ CS# goes high.
(Please refer to Figure 12)
(2) Write Disable (WRDI)
The Write Disable (WRDI) instruction is for resetting Write Enable Latch (WEL) bit.
The sequence of issuing WRDI instruction is: CS# goes low→ sending WRDI instruction code→ CS# goes high. (Please
refer to Figure 13)
The WEL bit is reset by following situations:
- Power-up
- Write Disable (WRDI) instruction completion
- Write Status Register (WRSR) instruction completion
- Page Program (PP, 4PP) instruction completion
- Sector Erase (SE) instruction completion
- Block Erase (BE, BE32K) instruction completion
- Chip Erase (CE) instruction completion
- Continuously Program mode (CP) instruction completion
- Single Block Lock/Unlock (SBLK/SBULK) instruction completion
- Gang Block Lock/Unlock (GBLK/GBULK) instruction completion
(3) Read Identification (RDID)
The RDID instruction is for reading the Manufacturer ID of 1-byte and followed by Device ID of 2-byte. The MXIC
Manufacturer ID is C2(hex), the memory type ID is 20(hex) as the first-byte Device ID, and the individual Device ID
of second-byte ID are listed as table of "ID Definitions". (Please refer to Table 8)
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. (Please refer to Figure 14)
While Program/Erase operation is in progress, it will not decode the RDID instruction, so there's no effect on the cy-
cle of program/erase operation which is currently in progress. When CS# goes high, the device is at standby stage.

MX25L6465E
MX25L12865E
(4) Read Status Register (RDSR)
The RDSR instruction is for reading Status Register. The Read Status Register can be read at any time (even in
program/erase/write status register condition) and continuously. It is recommended to check the Write in Progress (WIP)
bit before sending a new instruction when a program, erase, or write status register operation is in progress.
The sequence of issuing RDSR instruction is: CS# goes low→ sending RDSR instruction code→ Status Register
data out on SO (Please refer to Figure 15).
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 de-
vice 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.
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) of the device to against the program/erase instruction without hardware protection mode being
set. To write the Block Protect (BP3, BP2, BP1, BP0) bits requires the Write Status Register (WRSR) instruction to
be executed. Those bits define the protected area of the memory to against Page Program (PP), Sector Erase (SE),
Block Erase (BE) and Chip Erase (CE) instructions (only if all Block Protect bits set to 0, the CE instruction can be
executed).
QE bit. The Quad Enable (QE) bit, non-volatile bit, while it is "0" (factory default), it performs non-Quad and WP# is
enable. While QE is "1", it performs Quad I/O mode, WP# and HOLD# are disabled. In the other word, if the system
goes into four I/O mode (QE=1), the feature of HPM and HOLD will be disabled.
SRWD bit. The Status Register Write Disable (SRWD) bit, non-volatile bit, default value is "0". SRWD bit is operat-
ed together with Write Protection (WP#/SIO2) pin for providing hardware protection mode. The hardware protection
mode requires SRWD sets to 1 and WP#/SIO2 pin signal is low stage. In the hardware protection mode, the Write
Status Register (WRSR) instruction is no longer accepted for execution and the SRWD bit and Block Protect bits (BP3,
BP2, BP1, BP0) are read only.

(5) Write Status Register (WRSR)
The WRSR instruction is for changing the values of Status Register Bits. Before sending WRSR instruction, the
Write Enable (WREN) instruction must be decoded and executed to set the Write Enable Latch (WEL) bit in ad-
vance. The WRSR instruction can change the value of Block Protect (BP3, BP2, BP1, BP0) bits to define the pro-
tected area of memory (as shown in Table 2). The WRSR also can set or reset the Quad enable (QE) bit and set or
reset the Status Register Write Disable (SRWD) bit in accordance with Write Protection (WP#/SIO2) pin signal, but
has no effect on bit1(WEL) and bit0 (WIP) of the status register. The WRSR instruction cannot be executed once the
Hardware Protected Mode (HPM) is entered.
The sequence of issuing WRSR instruction is: CS# goes low→ sending WRSR instruction code→ Status Register
data on SI→ CS# goes high. (Please refer to Figure 16)
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
The self-timed Write Status Register cycle time (tW) is initiated as soon as Chip Select (CS#) goes high. The Write
in Progress (WIP) bit still can be check out during the Write Status Register cycle is in progress. The WIP sets 1
during the tW timing, and sets 0 when Write Status Register Cycle is completed, and the Write Enable Latch (WEL)
bit is reset.

Note: As defined by the values in the Block Protect (BP3, BP2, BP1, BP0) bits of the Status Register, as shown in Table 2.
As the above table showing, the summary of the Software Protected Mode (SPM) and Hardware Protected Mode (HPM).
Software Protected Mode (SPM):
-
When SRWD bit=0, no matter WP#/SIO2 is low or high, the WREN instruction may set the WEL bit and can
change the values of SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1,
BP0, is at software protected mode (SPM).
-
When SRWD bit=1 and WP#/SIO2 is high, the WREN instruction may set the WEL bit can change the values of
SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1, BP0, is at software pro-
tected 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 and hardware protected mode by the WP#/SIO2 to against data modification.
Note:
To exit the hardware protected mode requires WP#/SIO2 driving high once the hardware protected mode is entered.
If the WP#/SIO2 pin is permanently connected to high, the hardware protected mode can never be entered; only
can use software protected mode via BP3, BP2, BP1, BP0.
If the system goes into four I/O mode, the feature of HPM will be disabled.

(6) Read Data Bytes (READ)
The read instruction is for reading data out. The address is latched on rising edge of SCLK, and data shifts out on
the falling edge of SCLK at a maximum frequency fR. The first address byte can be at any location. The address
is automatically increased to the next higher address after each byte data is shifted out, so the whole memory can
be read out at a single READ instruction. The address counter rolls over to 0 when the highest address has been
reached.
The sequence of issuing READ instruction is: CS# goes low→ sending READ instruction code→3-byte address on
SI →data out on SO→ to end READ operation can use CS# to high at any time during data out. (Please refer to Fig-
ure 17)
(7) Read Data Bytes at Higher Speed (FAST_READ)
The FAST_READ instruction is for quickly reading data out. The address is latched on rising edge of SCLK, and
data of each bit shifts out on the falling edge of SCLK at a maximum frequency fC. The first address byte can be at
any location. The address is automatically increased to the next higher address after each byte data is shifted out,
so the whole memory can be read out at a single FAST_READ instruction. The address counter rolls over to 0 when
the highest address has been reached.
The sequence of issuing FAST_READ instruction is: CS# goes low→sending FAST_READ instruction code→3-byte
address on SI→ 1-dummy byte (default) address on SI→data out on SO→ to end FAST_READ operation can use
CS# to high at any time during data out. (Please refer to Figure 18)
While Program/Erase/Write Status Register cycle is in progress, FAST_READ instruction is rejected without any im-
pact on the Program/Erase/Write Status Register current cycle.
(8) Fast Double Transfer Rate Read (FASTDTRD)
The FASTDTRD instruction is for doubling reading data out, signals are triggered on both rising and falling edge of
clock. The address is latched on both rising and falling edge of SCLK, and data of each bit shifts out on both rising
and falling edge of SCLK at a maximum frequency fC2. The 2-bit address can be latched-in at one clock, and 2-bit
data can be read out at one clock, which means one bit at rising edge of clock, the other bit at falling edge of clock.
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 FASTDTRD instruction. The address counter rolls over to 0 when the highest
address has been reached.
The sequence of issuing FASTDTRD instruction is: CS# goes low → sending FASTDTRD instruction code (1bit
per clock) → 3-byte address on SI (2-bit per clock) → 6-dummy clocks (default) on SI → data out on SO (2-bit per
clock) → to end FASTDTRD operation can use CS# to high at any time during data out. (Please refer to Figure 19)
While Program/Erase/Write Status Register cycle is in progress, FASTDTRD instruction is rejected without any im-
pact on the Program/Erase/Write Status Register current cycle.
(9) 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 maxi-

mum frequency fT. The first address byte can be at any location. The address is automatically increased to the next
higher address after each byte data is shifted out, so the whole memory can be read out at a single 2READ instruc-
tion. The address counter rolls over to 0 when the highest address has been reached. Once writing 2READ instruc-
tion, the following address/dummy/data out will perform as 2-bit instead of previous 1-bit.
The sequence of issuing 2READ instruction is: CS# goes low→ sending 2READ instruction→ 24-bit address in-
terleave on SIO1 & SIO0→ 4-bit dummy cycle on SIO1 & SIO0→ data out interleave on SIO1 & SIO0→ to end
2READ operation can use CS# to high at any time during data out (Please refer to Figure 20 for 2 x I/O Read Mode
Timing Waveform).
While Program/Erase/Write Status Register cycle is in progress, 2READ instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.
(10) 2 x I/O Double Transfer Rate Read Mode (2DTRD)
The 2DTRD instruction enables Double Transfer Rate throughput on dual I/O of Serial Flash in read mode. The ad-
dress (interleave on dual I/O pins) is latched on both rising and falling edge of SCLK, and data (interleave on dual
I/O pins) shift out on both rising and falling edge of SCLK at a maximum frequency fT2. The 4-bit address can be
latched-in at one clock, and 4-bit data can be read out at one clock, which means two bits at rising edge of clock,
the other two bits at falling edge of clock. 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 2DTRD instruction. The address counter rolls over to 0 when the highest ad-
dress has been reached. Once writing 2DTRD instruction, the following address/dummy/ data out will perform as
4-bit instead of previous 1-bit.
The sequence of issuing 2DTRD instruction is: CS# goes low → sending 2DTRD instruction (1-bit per clock) → 24-
bit address interleave on SIO1 & SIO0 (4-bit per clock) → 6-bit dummy clocks on SIO1 & SIO0 → data out inter-
leave on SIO1 & SIO0 (4-bit per clock) → to end 2DTRD operation can use CS# to high at any time during data
out (Please refer to Figure 21 for 2 x I/O Double Transfer Rate Read Mode Timing Waveform).
While Program/Erase/Write Status Register cycle is in progress, 2DTRD instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.
(11) 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 ad-
dress counter rolls over to 0 when the highest address has been reached. Once writing 4READ instruction, the fol-
lowing 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 in-
terleave on SIO3, SIO2, SIO1 & SIO0→ 6 dummy cycles → data out interleave on SIO3, SIO2, SIO1 & SIO0→ to
end 4READ operation can use CS# to high at any time during data out (Please refer to Figure 22 for 4 x I/O Read
Mode Timing Waveform).
Another sequence of issuing 4 READ instruction especially useful in random access is : CS# goes low→ sending
4 READ instruction→ 3-bytes address interleave on SIO3, SIO2, SIO1 & SIO0 →performance enhance toggling bit

P[7:0]→ 4 dummy cycles → data out still CS# goes high → CS# goes low (reduce 4 Read instruction) → 24-bit ran-
dom access address (Please refer to Figure 23 for 4x I/O Read Enhance Performance Mode timing waveform).
In the performance-enhancing mode (Note of Figure. 23), 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.
(12) 4 x I/O Double Transfer Rate Read Mode (4DTRD)
The 4DTRD instruction enables Double Transfer Rate throughput on quad I/O of Serial Flash in read mode. A Quad
Enable (QE) bit of status Register must be set to "1" before sending the 4DTRD instruction. The address (interleave
on 4 I/O pins) is latched on both rising and falling edge of SCLK, and data (interleave on 4 I/O pins) shift out on
both rising and falling edge of SCLK at a maximum frequency fQ2. The 8-bit address can be latched-in at one clock,
and 8-bit data can be read out at one clock, which means four bits at rising edge of clock, the other four bits at fall-
ing edge of clock. 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 4DTRD instruc-
tion. The address counter rolls over to 0 when the highest address has been reached. Once writing 4DTRD instruc-
tion, the following address/dummy/data out will perform as 8-bit instead of previous 1-bit.
The sequence of issuing 4DTRD instruction is: CS# goes low → sending 4DTRD instruction (1-bit per clock) → 24-
bit address interleave on SIO3, SIO2, SIO1 & SIO0 (8-bit per clock) → 8 dummy clocks → data out interleave on
SIO3, SIO2, SIO1 & SIO0 (8-bit per clock) → to end 4DTRD operation can use CS# to high at any time during data
out (Please refer to Figure 24 for 4 x I/O Read Mode Double Transfer Rate Timing Waveform).
Another sequence of issuing enhanced mode of 4DTRD instruction especially useful in random access is: CS# goes
low → sending 4DTRD instruction (1-bit per clock) → 3-bytes address interleave on SIO3, SIO2, SIO1 & SIO0 (8-bit
per clock) → performance enhance toggling bit P[7:0] → 7 dummy clocks → data out(8-bit per clock) still CS#
goes high → CS# goes low (eliminate 4 Read instruction) → 24-bit random access address (Please refer to Figure
25 for 4x I/O Double Transfer Rate read enhance performance mode timing waveform).
While Program/Erase/Write Status Register cycle is in progress, 4DTRD instruction is rejected without any impact
on the Program/Erase/Write Status Register current cycle.
(13) 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 6) 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.
The sequence of issuing SE instruction is: CS# goes low → sending SE instruction code→ 3-byte address on SI
→CS# goes high. (Please refer to Figure 26)
The self-timed Sector Erase Cycle time (tSE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tSE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the

sector is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit still be reset.
(14) 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 (see table 6) 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. (Please refer to Figure 27)
The self-timed Block Erase Cycle time (tBE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tBE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If
the block is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit still be reset.
(15) Block Erase (BE32K)
The Block Erase (BE32) 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 execute to set the Write Enable Latch
(WEL) bit before sending the Block Erase (BE32). Any address of the block (see table 6) is a valid address for
Block Erase (BE32) 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 BE32 instruction is: CS# goes low → sending BE32 instruction code → 3-byte address on
SI → CS# goes high. (Please refer to Figure 27)
The self-timed Block Erase Cycle time (tBE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Sector Erase cycle is in progress. The WIP sets 1 during the
tBE timing, and sets 0 when Sector Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If
the block is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit still be reset.
(16) Chip Erase (CE)
The Chip Erase (CE) instruction is for erasing the data of the whole chip to be "1". A Write Enable (WREN) instruc-
tion must 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. (Please
refer to Figure 28)
The self-timed Chip Erase Cycle time (tCE) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Chip Erase cycle is in progress. The WIP sets 1 during the tCE
timing, and sets 0 when Chip Erase Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If the chip is

24
MX25L6465E
MX25L12865E
protected the Chip Erase (CE) instruction will not be executed, but WEL will be reset.
(17) Page Program (PP)
The Page Program (PP) instruction is for programming the memory to be "0". A Write Enable (WREN) instruction
must execute to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). The device programs
only the last 256 data bytes sent to the device. If the entire 256 data bytes are going to be programmed, A7-A0
(The eight least significant address bits) should be set to 0. If the eight least significant address bits (A7-A0) are not
all 0, all transmitted data going beyond the end of the current page are programmed from the start address of the
same page (from the address A7-A0 are all 0). If more than 256 bytes are sent to the device, the data of the last
256-byte is programmed at the request page and previous data will be disregarded. If less than 256 bytes are sent
to the device, the data is programmed at the requested address of the page without effect on other address of the
same page.
The sequence of issuing PP instruction is: CS# goes low→ sending PP instruction code→ 3-byte address on SI→
at least 1-byte on data on SI→ CS# goes high. (Please refer to Figure 29)
The CS# must be kept to low during the whole Page Program cycle; The CS# must go high exactly at the byte
boundary( the latest eighth bit of data being latched in), otherwise, the instruction will be rejected and will not be
executed.
The self-timed Page Program Cycle time (tPP) is initiated as soon as Chip Select (CS#) goes high. The Write in
Progress (WIP) bit still can be check out during the Page Program cycle is in progress. The WIP sets 1 during the
tPP timing, and sets 0 when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is reset. If
the page is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit will still be reset.
(18) 4 x I/O Page Program (4PP)
The Quad Page Program (4PP) instruction is for programming the memory to be "0". A Write Enable (WREN)
instruction must execute to set the Write Enable Latch (WEL) bit and Quad Enable (QE) bit must be set to "1"
before sending the Quad Page Program (4PP). The Quad Page Programming takes four pins: SIO0, SIO1, SIO2,
and SIO3, which can raise programer performance and and the effectiveness of application of lower clock less
than 20MHz. For system with faster clock, the Quad page program cannot provide more actual favors, because
the required internal page program time is far more than the time data flows in. Therefore, we suggest that while
executing this command (especially during sending data), user can slow the clock speed down to 20MHz below.
The other function descriptions are as same as standard page program.
The sequence of issuing 4PP instruction is: CS# goes low→ sending 4PP instruction code→ 3-byte address on
SIO[3:0]→ at least 1-byte on data on SIO[3:0]→ CS# goes high. (Please refer to Figure 30)
If the page is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit will still be reset.

(19) Continuously program mode (CP mode)
The CP mode may enhance program performance by automatically increasing address to the next higher address
after each byte data has been programmed.
The Continuously program (CP) instruction is for multiple byte program to Flash. A write Enable (WREN) instruction
must execute to set the Write Enable Latch (WEL) bit before sending the Continuously program (CP) instruction.
CS# requires to go high before CP instruction is executing. After CP instruction and address input, two bytes of
data is input sequentially from MSB(bit7) to LSB(bit0). The first byte data will be programmed to the initial address
range with A0=0 and second byte data with A0=1. If only one byte data is input, the CP mode will not process. If
more than two bytes data are input, the additional data will be ignored and only two byte data are valid. Any byte to
be programmed should be in the erase state (FF) first. It will not roll over during the CP mode, once the last unpro-
tected address has been reached, the chip will exit CP mode and reset write Enable Latch bit (WEL) as "0" and CP
mode bit as "0". Please check the WIP bit status if it is not in write progress before entering next valid instruction.
During CP mode, the valid commands are CP command (AD hex), WRDI command (04 hex), RDSR command (05
hex), and RDSCUR command (2B hex). And the WRDI command is valid after completion of a CP programming cy-
cle, which means the WIP bit=0.
The sequence of issuing CP instruction is : CS# goes low → sending CP instruction code → 3-byte address on SI
pin → two data bytes on SI → CS# goes high to low → sending CP instruction and then continue two data bytes
are programmed → CS# goes high to low -> till last desired two data bytes are programmed → CS# goes high to
low →sending WRDI (Write Disable) instruction to end CP mode → send RDSR instruction to verify if CP mode
word program ends, or send RDSCUR to check bit4 to verify if CP mode ends. (Please refer to Figure 31 of CP
mode timing waveform)
Three methods to detect the completion of a program cycle during CP mode:
1) Software method-I: by checking WIP bit of Status Register to detect the completion of CP mode.
2) Software method-II: by waiting for a tBP time out to determine if it may load next valid command or not.
3) Hardware method: by writing ESRY (enable SO to output RY/BY#) instruction to detect the completion of a
program cycle during CP mode. The ESRY instruction must be executed before CP mode execution. Once it is
enable in CP mode, the CS# goes low will drive out the RY/BY# status on SO, "0" indicates busy stage, "1" indi-
cates ready stage, SO pin outputs tri-state if CS# goes high. DSRY (disable SO to output RY/BY#) instruction to
disable the SO to output RY/BY# and return to status register data output during CP mode. Please note that the
ESRY/DSRY command are not accepted unless the completion of CP mode.
If the page is protected by BP3~0 (WPSEL=0) or by individual lock (WPSEL=1), the array data will be protected (no
change) and the WEL bit will still be reset.
(20) Parallel Mode (Highly recommended for production throughputs increasing)
The parallel mode provides 8 bit inputs/outputs for increasing throughputs of factory production purpose. The
parallel mode requires 55h command code, after writing the parallel mode command and then CS# going high,
after that, the Memory can be available to accept RDID/RES & REMS/READ/PP command as the normal writing
command procedure. To exit parallel mode, it requires 45h command code, or power-off/on sequence. The
sequence of issuing Paralle Mode instruction is : CS# goes low→sending Parallel Mode Code→CS# goes high (Please
refer to Figure 32-1, and refer to Figure 32-2~32-7 for other parallel mode).
a. For normal write command (by SI), No effect
b. Under parallel mode, the fastest access clock freq. will be changed to 6MHz (SCLK pin clock freq.)
c. For parallel mode, the tV will be changed to 70ns.

(21) Deep Power-down (DP)
The Deep Power-down (DP) instruction is for setting the device on the minimizing the power consumption (to enter-
ing the Deep Power-down mode), the standby current is reduced from ISB1 to ISB2). The Deep Power-down mode
requires the Deep Power-down (DP) instruction to enter, during the Deep Power-down mode, the device is not ac-
tive and all Write/Program/Erase instruction are ignored. When CS# goes high, it's only in standby mode not deep
power-down mode. It's different from Standby mode.
The sequence of issuing DP instruction is: CS# goes low→ sending DP instruction code→ CS# goes high. (Please
refer to Figure 33)
Once the DP instruction is set, all instruction will be ignored except the Release from Deep Power-down mode (RDP)
and Read Electronic Signature (RES) instruction. (those instructions allow the ID being reading out). When Power-
down, the deep power-down mode automatically stops, and when power-up, the device automatically is in standby
mode. For RDP instruction the CS# must go high exactly at the byte boundary (the latest eighth bit of instruction
code been latched-in); otherwise, the instruction will not executed. As soon as Chip Select (CS#) goes high, a delay
of tDP is required before entering the Deep Power-down mode and reducing the current to ISB2.
(22) Release from Deep Power-down (RDP), Read Electronic Signature (RES)
The Release from Deep Power-down (RDP) instruction is terminated by driving Chip Select (CS#) High. When Chip
Select (CS#) is driven High, the device is put in the 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 10. 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 of
ID Definitions. This is not the same as RDID instruction. It is not recommended to use for new design. For new
design, please use RDID instruction. Even in Deep power-down mode, the RDP and RES are also allowed to be
executed, only except the device is in progress of program/erase/write cycles; there's no effect on the current pro-
gram/erase/write cycles in progress. The sequence is shown as Figure 34,35.
The RES instruction is ended by CS# goes high after the ID been read out at least once. The ID outputs repeat-
edly if continuously send the additional clock cycles on SCLK while CS# is at low. If the device was not previously
in Deep Power-down mode, the device transition to standby mode is immediate. If the device was previously in
Deep Power-down mode, there's a delay of tRES2 to transit to standby mode, and CS# must remain to high at
least tRES2(max). Once in the standby mode, the device waits to be selected, so it can be receive, decode, and
execute instruction.
The RDP instruction is for releasing from Deep Power-down Mode.
(23) Read Electronic Manufacturer ID & Device ID (REMS), (REMS2), (REMS4), (REMS4D)
The REMS, REMS2, REMS4 and REMS4D instruction provides both the JEDEC assigned Manufacturer ID and the
specific Device ID.
The instruction is initiated by driving the CS# pin low and shift the instruction code "90h", "CFh", "DFh" or "EFh" fol-
lowed by two dummy bytes and one bytes address (A7~A0). After which, the Manufacturer ID for MXIC (C2h) and
the Device ID are shifted out on the falling edge of SCLK with most significant bit (MSB) first as shown in Figure 36.
The Device ID values are listed in table of ID Definitions. If the one-byte address is initially set to 01h, then the De-
vice 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.

(24) Enter Secured OTP (ENSO)
The ENSO instruction is for entering the additional 4K-bit Secured OTP mode. The additional 4K-bit Secured OTP
is independent from main array, which may use to store unique serial number for system identifier. After entering
the Secured OTP mode, and then follow standard read or program, procedure to read out the data or update data.
The Secured OTP data cannot be updated again once it is lock-down.
The sequence of issuing ENSO instruction is: CS# goes low→ sending ENSO instruction to enter Secured OTP
mode→ CS# goes high.
Please note that WRSR/WRSCUR/WPSEL/SBLK/GBLK/SBULK/GBULK/CE/BE/SE/BE32K commands are not ac-
ceptable during the access of secure OTP region, once Security OTP is lock down, only read related commands
are valid.
(25) Exit Secured OTP (EXSO)
The EXSO instruction is for exiting the additional 4K-bit Secured OTP mode.
The sequence of issuing EXSO instruction is: CS# goes low→ sending EXSO instruction to exit Secured OTP
mode→ CS# goes high.
(26) Read Security Register (RDSCUR)
The RDSCUR instruction is for reading the value of Security Register. 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 Regis-
ter data out on SO→ CS# goes high.
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 before ex- factory
or not. When it is "0", it indicates non-factory lock; "1" indicates factory- lock.
Lock-down Secured OTP (LDSO) bit. By writing WRSCUR instruction, the LDSO bit may be set to "1" for cus-
tomer lock-down purpose. However, once the bit is set to "1" (lock-down), the LDSO bit and the 4K-bit Secured
OTP area cannot be update any more. While it is in 4K-bit Secured OTP mode, array access is not allowed.

MX25L12865E
Continuously Program Mode( CP mode) bit. The Continuously Program Mode bit indicates the status of CP
mode, "0" indicates not in CP mode; "1" indicates in CP mode.
Program Fail Flag bit. While a program failure happened, the Program Fail Flag bit would be set. This bit will also
be set when the user attempts to program a protected main memory region or a locked OTP region. This bit can in-
dicate whether one or more of program operations fail, and can be reset by command CLSR (30h)
Erase Fail Flag bit. While a erase failure happened, the Erase Fail Flag bit would be set. This bit will also be set
when the user attempts to erase a protected main memory region or a locked OTP region. This bit can indicate
whether one or more of erase operations fail, and can be reset by command CLSR (30h)
Write Protection Select bit. The Write Protection Select bit indicates that WPSEL has been executed successfully.
Once this bit has been set (WPSEL=1), all the blocks or sectors will be write-protected after the power-on every
time. Once WPSEL has been set, it cannot be changed again, which means it's only for individual WP mode.
Under the individual block protection mode (WPSEL=1), hardware protection is performed by driving WP#=0. Once
WP#=0 all array blocks/sectors are protected regardless of the contents of SRAM lock bits.

(27) Write Security Register (WRSCUR)
The WRSCUR instruction is for changing the values of Security Register Bits. Unlike write status register, the WREN
instruction is not required before sending WRSCUR instruction. The WRSCUR instruction may change the values
of bit1 (LDSO bit) for customer to lock-down the 4K-bit Secured OTP area. Once the LDSO bit is set to "1", the Se-
cured OTP area cannot be updated any more.
The sequence of issuing WRSCUR instruction is :CS# goes low→ sending WRSCUR instruction → CS# goes high.
The CS# must go high exactly at the boundary; otherwise, the instruction will be rejected and not executed.

(28) Write Protection Selection (WPSEL)
There are two write protection methods, (1) BP protection mode (2) individual block protection mode. If WPSEL=0,
flash is under BP protection mode . If WPSEL=1, flash is under individual block protection mode. The default value
of WPSEL is “0”. WPSEL command can be used to set WPSEL=1. Please note that WPSEL is an OTP bit. Once
WPSEL is set to 1, there is no chance to recovery WPSEL back to “0”. If the flash is put on BP mode, the indi-
vidual block protection mode is disabled. Contrarily, if flash is on the individual block protection mode, the BP mode
is disabled.
Every time after the system is powered-on, and the Security Register bit 7 is checked to be WPSEL=1, all
the blocks or sectors will be write protected by default. User may only unlock the blocks or sectors via SBULK
and GBULK instruction. Program or erase functions can only be operated after the Unlock instruction is conducted.
BP protection mode, WPSEL=0:
ARRAY is protected by BP3~BP0 and BP3~BP0 bits are protected by “SRWD=1 and WP#=0”, where SRWD is bit 7
of status register that can be set by WRSR command.
Individual block protection mode, WPSEL=1:
Blocks are individually protected by their own SRAM lock bits which are set to “1” after power up. SBULK and SBLK
command can set SRAM lock bit to “0” and “1”. When the system accepts and executes WPSEL instruction, the bit
7 in security register will be set. It will activate SBLK, SBULK, RDBLOCK, GBLK, GBULK etc instructions to conduct
block lock protection and replace the original Software Protect Mode (SPM) use (BP3~BP0) indicated block meth-
ods.Under the individual block protection mode (WPSEL=1), hardware protection is performed by driving WP#=0.
Once WP#=0 all array blocks/sectors are protected regardless of the contents of SRAM lock bits.
The sequence of issuing WPSEL instruction is: CS# goes low → sending WPSEL instruction to enter the individual
block protect mode → CS# goes high.

(29) Single Block Lock/Unlock Protection (SBLK/SBULK)
These instructions are only effective after WPSEL was executed. The SBLK instruction is for write protection a spec-
ified block(or sector) of memory, using A23-A16 or (A23-A12) address bits to assign a 64Kbyte block (or 4K bytes
sector) to be protected as read only. The SBULK instruction will cancel the block (or sector) write protection state.
This feature allows user to stop protecting the entire block (or sector) through the chip unprotect command (GBULK).
The WREN (Write Enable) instruction is required before issuing SBLK/SBULK instruction.
The sequence of issuing SBLK/SBULK instruction is: CS# goes low → send SBLK/SBULK (36h/39h) instruction →
send 3 address bytes assign one block (or sector) to be protected on SI pin → CS# goes high. (Please refer to Fig-
ure 38)
The CS# must go high exactly at the byte boundary, otherwise the instruction will be rejected and not be executed.

(30) Read Block Lock Status (RDBLOCK)
This instruction is only effective after WPSEL was executed. The RDBLOCK instruction is for reading the status of
protection lock of a specified block(or sector), using A23-A16 (or A23-A12) address bits to assign a 64K bytes block (4K
bytes sector) and read protection lock status bit which the first byte of Read-out cycle. The status bit is"1" to indicate
that this block has be protected, that user can read only but cannot write/program /erase this block. The status bit is
"0" to indicate that this block hasn't be protected, and user can read and write this block.
The sequence of issuing RDBLOCK instruction is: CS# goes low → send RDBLOCK (3Ch) instruction → send 3 ad-
dress bytes to assign one block on SI pin → read block's protection lock status bit on SO pin → CS# goes high. (Please
refer to Figure 39)
(31) Gang Block Lock/Unlock (GBLK/GBULK)
These instructions are only effective after WPSEL was executed. The GBLK/GBULK instruction is for enable/disable
the lock protection block of the whole chip.
The WREN (Write Enable) instruction is required before issuing GBLK/GBULK instruction.
The sequence of issuing GBLK/GBULK instruction is: CS# goes low → send GBLK/GBULK (7Eh/98h) instruction →
CS# goes high. (Please refer to Figure 40)
The CS# must go high exactly at the byte boundary, otherwise, the instruction will be rejected and not be executed.
(32) Clear SR Fail Flags (CLSR)
The CLSR instruction is for resetting the Program/Erase Fail Flag bit of Security Register. It should be executed be-
fore program/erase another block during programming/erasing flow without read array data.
The sequence of issuing CLSR instruction is: CS# goes low → send CLSR instruction code → CS# goes high.
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
(33) Enable SO to Output RY/BY# (ESRY)
The ESRY instruction is for outputting the ready/busy status to SO during CP mode.
The sequence of issuing ESRY instruction is: CS# goes low → sending ESRY instruction code → CS# goes high.
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.
(34) Disable SO to Output RY/BY# (DSRY)
The DSRY instruction is for resetting ESRY during CP mode. The ready/busy status will not output to SO after
DSRY issued.
The sequence of issuing DSRY instruction is: CS# goes low → send DSRY instruction code → CS# goes high.
The CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed.

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

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

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.
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.
Please refer to the figure of "Power-up Timing".
Note:
- To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommended.

Note:
(1) During CP mode, the valid commands are CP command (AD hex), WRDI command (04 hex), RDSR command
(05 hex), and RDSCUR command (2B hex).
(2) Once an internal programming operation begins, CS# goes low will drive the status on the SO pin and CS#
goes high will return the SO pin to tri-state.
(3) To end the CP mode, either reaching the highest unprotected address or sending Write Disable (WRDI) com-
mand (04 hex) may achieve it and then it is recommended to send RDSR command (05 hex) to verify if CP
mode is ended.

OPERATING CONDITIONS
At Device Power-Up and Power-Down
AC timing illustrated in Figure 42 and Figure 43 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.
