IS25LP128
GENERAL DESCRIPTION
The IS25LP128 Serial Flash memory offers a storage solution with the flexibility and performance in a simplified
pin count package. ISSI’s “Industry Standard Serial Interface” Flash are for systems that have limited space,
pins, and power. The IS25LP128 are accessed through a 4-wire SPI Interface consisting of a Serial Data Input
(Sl), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins, which also serve as multi-I/O
(see pin descriptions).
The device supports the standard Serial Peripheral Interface (SPI), Dual/Quad output (SPI), and Dual/Quad I/O
(SPI). Clock frequencies of up to 133MHz allow for equivalent clock rates of up to 532MHz (133MHz x 4)
allowing more than 66Mbytes/s of throughput. The IS25xP series of Flash adds support for DTR (Double
Transfer Rate) commands that transfer addresses and read data on both edges of the clock. These transfer
rates can outperform 16-bit Parallel Flash memories allowing for efficient memory access for a XIP (execute in
place) operation.
The memory array is organized into programmable pages of 256-bytes each. The IS25LP128 supports page
program mode where 1 to 256 bytes of data can be programmed into the memory with one command. QPI
(Quad Peripheral Interface) supports 2-cycle instruction further reducing instruction times. Pages can be erased
in groups of 4K-byte sectors, 32K-byte blocks, 64K-byte blocks, and/or the entire chip. The uniform sectors and
blocks allow greater flexibility for a variety of applications requiring solid data retention.
GLOSSARY
Standard SPI
The IS25LP128 is accessed through a 4-wire SPI Interface consisting of Serial Data Input (Sl), Serial Data
Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. Instructions are inputted through the SI pin to
encode instructions, addresses, or input data to the device on the rising edge of SCK. The DO pin is used to
read data or check the status of the device on the falling edge of SCK. This device supports SPI bus operation
mode (0,0) and (1,1).
Mutil I/O SPI
The IS25LP128 allows accessing enhanced SPI protocol to use Dual output, Dual input and output, and Quad
input and output operation. Executing these instructions through SPI mode will achieve double or quadruple the
transfer bandwidth for READ and PROGRAM.
Quad I/O QPI
The IS25LP128 can enable QPI protocol by issuing an “Enter QPI mode (35h)” command. The QPI mode uses
four IO pins for input and output to reduce SPI instruction overhead and increase output bandwidth. QPI mode
can exit by issuing an “Exit QPI (F5h) command. A power reset or software reset can also return the device into
the standard SPI mode. SI and SO pins become bidirectional IO0 and IO1, and WP# and HOLD# pins become
IO2 and IO3 respectively during QPI mode.
DTR
In addition to SPI and QPI features, IS25LP128 also supports SPI DTR READ. SPI DTR allows high data
throughput while running at lower clock frequencies. As SPI DTR READ option uses both rising and falling clock
to drive output, the dummy cycles are reduced by half as well.
Programmable drive strength and Selectable burst setting.
The IS25LP128 offers programmable output drive strength and selectable burst (wrap) length features to
increase the efficiency and performance of READ operations. The driver strength and burst setting features are
controlled by setting READ registers. A total of six different drive strengths and four different burst sizes
(8/16/32/64 Bytes) are selectable.

SYMBOL
TYPE
DESCRIPTION
Chip Enable: The Chip Enable (CE#) pin enables and disables the devices
operation. When CE# is high the device is deselected and output pins are in a high
impedance state. When deselected the devices non-critical internal circuitry power
down to allow minimal levels of power consumption while in a standby state.
CE#
INPUT
When CE# is pulled low the device will be selected and brought out of standby
mode. The device is considered active and instructions can be written to, data read,
and written to the device. After power-up, CE# must transition from high to low
before a new instruction will be accepted.
Keeping CE# in a high state deselects the device and switches it into its low power
state. Data will not be accepted when CE# is high.
Serial Data Input, Serial Output, and IOs (SI, SO, IO0, and IO1):
SI (IO0),
SO (IO1)
INPUT/OUTPUT
This device supports standard SPI, Dual SPI, and Quad SPI operation. Standard SPI
instructions use the unidirectional SI (Serial Input) pin to write instructions,
addresses, or data to the device on the rising edge of the Serial Clock (SCK).
Standard SPI also uses the unidirectional SO (Serial Output) to read data or status
from the device on the falling edge of the serial clock (SCK).
In Dual and Quad SPI mode, SI and SO become bidirectional IO pins to write
instructions, addresses or data to the device on the rising edge of the Serial Clock
(SCK) and read data or status from the device on the falling edge of SCK. Quad SPI
instructions use the WP# and HOLD# pins as IO2 and IO3 respectively.
WP# (IO2)
INPUT/OUTPUT
Write Protect/Serial Data IO (IO2): The WP# pin protects the Status Register from
being written. When the WP# is low the status registers are write-protected and viceversa for high. When the QE bit is set to “1”, the WP# pin (Write Protect) function is
not available since this pin is used for IO2.
Hold/Serial Data IO (IO3): Pauses serial communication by the master device
without resetting the serial sequence. When the QE bit of Status Register is set to
“1”, HOLD# pin is not available since it becomes IO3.
HOLD# (IO3)
INPUT/OUTPUT
The HOLD# pin allows the device to be paused while it is selected. The HOLD# pin
is active low. When HOLD# is in a low state, and CE# is low, the SO pin will be at
high impedance.
Device operation can resume when HOLD# pin is brought to a high state. When the
QE bit of Status Register is set for Quad I/O, the HOLD# pin function is not available
and becomes IO3 for Multi-I/O SPI mode.

4. SPI MODES DESCRIPTION
Multiple IS25LP128 devices can be connected on the SPI serial bus and controlled by a SPI Master, i.e.
microcontroller, as shown in Figure 4.1. The devices support either of two SPI modes:
Mode 0 (0, 0)
Mode 3 (1, 1)
The difference between these two modes is the clock polarity. When the SPI master is in stand-by mode, the
serial clock remains at “0” (SCK = 0) for Mode 0 and the clock remains at “1” (SCK = 1) for Mode 3. Please refer
to Figure 4.2 and Figure 4.3 for SPI and QPI mode. In both modes, the input data is latched on the rising edge
of Serial Clock (SCK), and the output data is available from the falling edge of SCK.

The BP0, BP1, BP2, BP3, SRWD, and QE are non-volatile memory cells that can be written by a Write Status
Register (WRSR) instruction. The default value of the BP2, BP1, BP0, and SRWD bits were set to “0” at factory.
The Status Register can be read by the Read Status Register (RDSR).
The function of Status Register bits are described as follows:
WIP bit: The Write In Progress (WIP) bit is read-only, and can be used to detect the progress or completion of a
program or erase operation. When the WIP bit is “0”, the device is ready for write status register, program or
erase operation. When the WIP bit is “1”, the device is busy.
WEL bit: The Write Enable Latch (WEL) bit indicates the status of the internal write enable latch. When the
WEL is “0”, the write enable latch is disabled and all write operations, including write status register, write
configuration register, page program, sector erase, block and chip erase operations are inhibited. When the
WEL bit is “1”, write operations are allowed. The WEL bit is set by a Write Enable (WREN) instruction. Each
write register, program and erase instruction must be preceded by a WREN instruction. The WEL bit can be
reset by a Write Disable (WRDI) instruction. It will automatically be reset after the completion of any write
operation.

IS25LP128
BP3, BP2, BP1, BP0 bits: The Block Protection (BP3, BP2, BP1 and BP0) bits are used to define the portion of
the memory area to be protected. Refer to Tables 6.3 for the Block Write Protection (BP) bit settings. When a
defined combination of BP3, BP2, BP1 and BP0 bits are set, the corresponding memory area is protected. Any
program or erase operation to that area will be inhibited.
Note: A Chip Erase (CER) instruction will be ignored unless all the Block Protection Bits are “0”s.
SRWD bit: The Status Register Write Disable (SRWD) bit operates in conjunction with the Write Protection
(WP#) signal to provide a Hardware Protection Mode. When the SRWD is set to “0”, the Status Register is not
write-protected. When the SRWD is set to “1” and the WP# is pulled low (VIL), the bits of Status Register
(SRWD, BP3, BP2, BP1, BP0) become read-only, and a WRSR instruction will be ignored. If the SRWD is set to
“1” and WP# is pulled high (VIH), the Status Register can be changed by a WRSR instruction.
QE bit: The Quad Enable (QE) is a non-volatile bit in the status register that allows quad operation. When the
QE bit is set to “0”, the pin WP# and HOLD# are enabled. When the QE bit is set to “1”, the IO2 and IO3 pins
are enabled.

6.3 READ REGISTERS
Read Register format and Bit definitions pertaining to QPI mode are described below.’
READ PARAMETER BITS
Table 6.6 defines all bits that control features in SPI/QPI modes. The ODS2, ODS1, ODS0 (P7, P6, P5) bits
provide a method to set and control driver strength. The Dummy Cycle bits (P4, P3) define how many dummy
cycles are used during various READ modes. The wrap selection bits (P2, P1, P0) define burst length with wrap
around.
The SET READ PARAMETERS Operation (SRP, C0h) is used to set all the Read Register bits, and can thereby
define the output driver strength, number of dummy cycles used during READ modes, burst length with wrap
around.

7. PROTECTION MODE
The IS25LP128 supports hardware and software write-protection mechanisms.
7.1 HARDWARE WRITE PROTECTION
The Write Protection (WP#) pin provides a hardware write protection method for BP3, BP2, BP1, BP0, SRWD,
and QE in the Status Register. Refer to the section 6.1 STATUS REGISTER.
Write inhibit voltage is 2.1V. All write sequence will be ignored when Vcc drops to 2.1V or lower.
7.2 SOFTWARE WRITE PROTECTION
The IS25LP128 also provides a software write protection feature. The Block Protection (BP3, BP2, BP1, BP0)
bits allow part or the whole memory area to be write-protected.

8. DEVICE OPERATION
The IS25LP128 utilizes an 8-bit instruction register. Refer to Table 8.1. Instruction Set for details on instructions
and instruction codes. All instructions, addresses, and data are shifted in with the most significant bit (MSB) first
on Serial Data Input (SI) or Serial Data IOs (IO0, IO1, IO2, IO3). The input data on SI or IOs is latched on the
rising edge of Serial Clock (SCK) for normal mode and both of rising and falling edges for DTR mode after Chip
Enable (CE#) is driven low (VIL). Every instruction sequence starts with a one-byte instruction code and is
followed by address bytes, data bytes, or both address bytes and data bytes, depending on the type of
instruction. CE# must be driven high (VIH) after the last bit of the instruction sequence has been shifted in to end
the operation.

8.1 NORMAL READ OPERATION (NORD, 03h)
The Normal Read Data (NORD) instruction is used to read memory contents of the IS25LP128 at a maximum
frequency of 50MHz.
The NORD instruction code is transmitted via the Sl line, followed by three address bytes (A23 - A0) of the first
memory location to be read. A total of 24 address bits are shifted in. The first byte address can be at any
memory location. Upon completion, any data on the Sl will be ignored. Refer to Table 8.2 for the related
Address Key.
The first byte data (D7 - D0) is shifted out on the SO line, MSB first. A single byte of data, or up to the whole
memory array, can be read out in one READ instruction. The address is automatically incremented by one after
each byte of data is shifted out. The read operation can be terminated at any time by driving CE# high (VIH)
after the data comes out. When the highest address of the device is reached, the address counter will roll over
to the 000000h address, allowing the entire memory to be read in one continuous READ instruction.
If a Read Data instruction is issued while an Erase, Program or Write operation is in process (WIP=1) the
instruction is ignored and will not have any effects on the current operation.

8.2 FAST READ DATA OPERATION (FRD, 0Bh)
The FAST READ (FRD) instruction is used to read memory data at up to a 133MHz clock.
The FAST READ instruction code is followed by three address bytes (A23 - A0) and a dummy byte (8 clocks),
transmitted via the SI line, with each bit latched-in during the rising edge of SCK. Then the first data byte from
the address is shifted out on the SO line, with each bit shifted out at a maximum frequency fCT, during the falling
edge of SCK.
The first byte addressed can be at any memory location. The address is automatically incremented after each
byte of data is shifted out. When the highest address is reached, the address counter will roll over to the
000000h address, allowing the entire memory to be read with a single FAST READ instruction. The FAST
READ instruction is terminated by driving CE# high (VIH). If a Fast Read Data instruction is issued while an
Erase, Program or Write cycle is in process (WIP=1) the instruction is ignored and will not have any effects on
the current cycle.

FAST READ DATA QPI OPERATION (FRD QPI, 0Bh)
The QPI FAST READ (FRD QPI) instruction is used to read memory data at up to a 133MHz clock.
The FAST READ instruction code (2 clocks) is followed by three address bytes (A23-A0—6clocks) and mode
bits, dummy byte (4clocks), transmitted via the QPI line, with each bit latched-in during the rising edge of SCK.
Then the first data byte addressed is shifted out on the SO line, with each bit shifted out at a maximum
frequency fCT, during the falling edge of SCK.
.
The first byte addressed can be at any memory location. The address is automatically incremented after each
byte of data is shifted out. When the highest address is reached, the address counter will roll over to the
000000h address, allowing the entire memory to be read with a single FAST_READ instruction. The
FAST_READ instruction is terminated by driving CE# high (VIH). If a Fast Read Data instruction is issued while
an Erase, Program or Write cycle is in process (WIP=1) the instruction is ignored and will not have any effects
on the current cycle

8.3 HOLD OPERATION
HOLD# is used in conjunction with CE# to select the IS25LP128. When the device is selected and a serial
sequence is underway, HOLD# can be used to pause the serial communication with the master device without
resetting the serial sequence. To pause, HOLD# is brought low while the SCK signal is low. To resume serial
communication, HOLD# is brought high while the SCK signal is low (SCK may still toggle during HOLD). Inputs
to SlO will be ignored while SO is in the high impedance state.
Note: HOLD is not supported in DTR mode or with QE=1.
Timing graph can be referenced in AC Parameters Figure 9.3
8.4 FAST READ DUAL I/O OPERATION (FRDIO, BBh)
The FRDIO allows the address bits to be input two bits at a time. This may allow for code to be executed directly
from the SPI in some applications.
The FRDIO instruction code is followed by three address bytes (A23 – A0) and a mode byte, transmitted via the
IO0 and IO1 lines, with each pair of bits latched-in during the rising edge of SCK. The address MSB is input on
IO1, the next bit on IO0, and continues to shift in alternating on the two lines. The mode bit contains the value
Ax, where x is a “don’t care” value. Then the first data byte addressed is shifted out on the IO1 and IO0 lines,
with each pair of bits shifted out at a maximum frequency fCT, during the falling edge of SCK. The MSB is output
on IO1, while simultaneously the second bit is output on IO0. Figure 8.4 illustrates the timing sequence.
The first byte addressed can be at any memory location. The address is automatically incremented after each
byte of data is shifted out. When the highest address is reached, the address counter will roll over to the
000000h address, allowing the entire memory to be read with a single FRDIO instruction. FRDIO instruction is
terminated by driving CE# high (VIH).
The device expects the next operation will be another FRDIO. It remains in this mode until it receives a Mode
Reset (FFh) command. In subsequent FRDIO execution, the command code is skipped. It saves timing cycles
as described in Figure 8.5. If a FRDIO instruction is issued while an Erase, Program or Write cycle is in process
(WIP=1) the instruction is ignored and will not have any effects on the current cycle.

8.5 FAST READ DUAL OUTPUT OPERATION (FRDO, 3Bh)
The FRDO instruction is used to read memory data on two output pins each at up to a 133MHz clock.
The FRDO instruction code is followed by three address bytes (A23 – A0) and a dummy byte (8 clocks),
transmitted via the SI line, with each bit
latched-in during the rising edge of SCK. Then the first data byte addressed is shifted out on the SO and SIO lines,
with each pair of bits shifted out at a maximum frequency fCT, during the falling edge of SCK. The first bit (MSB)
is output on SO, while simultaneously the second bit is output on SIO.
The first byte addressed can be at any memory location. The address is automatically incremented after each byte
of data is shifted out. When the highest address is reached, the address counter will roll over to the 000000h
address, allowing the entire memory to be read with a single FRDO instruction. FRDO instruction is terminated by
driving CE# high (VIH). If a FRDO instruction is issued while an Erase, Program or Write cycle is in process
(BUSY=1) the instruction is ignored and will not have any effects on the current cycle.

8.6 FAST READ QUAD I/O OPERATION (FRQIO, EBh)
The FRQIO instruction allows the address bits to be input four bits at a time. This may allow for code to be
executed directly from the SPI in some applications.
The FRQIO instruction code is followed by three address bytes (A23 – A0) and a mode byte, transmitted via the
IO3, IO2, IO0 and IO1 lines, with each group of four bits latched-in during the rising edge of SCK. The address
of MSB inputs on IO3, the next bit on IO2, the next bit on IO1, the next bit on IO0, and continue to shift in
alternating on the four. The mode byte contains the value Ax, where x is a “don’t care” value. After four dummy
clocks, the first data byte addressed is shifted out on the IO3, IO2, IO1 and IO0 lines, with each group of four
bits shifted out at a maximum frequency fCT, during the falling edge of SCK. The first bit (MSB) is output on IO3,
while simultaneously the second bit is output on IO2, the third bit is output on IO1, etc. Figure 8.7 illustrates the
timing sequence.
The first byte addressed can be at any memory location. The address is automatically incremented after each
byte of data is shifted out. When the highest address is reached, the address counter will roll over to the
000000h address, allowing the entire memory to be read with a single FRQIO instruction. FRQIO instruction is
terminated by driving CE# high (VIH).
The device expects the next operation will be another FRQIO. It remains in this mode until it receives a Mode
Reset (FFh) command. In subsequent FRDIO execution, the command code is not input, saving cycles as
described in Figure 8.8. If a FRQIO instruction is issued while an Erase, Program or Write cycle is in process
(WIP=1) the instruction is ignored and will not have any effects on the current cycle.

8.7 PAGE PROGRAM OPERATION (PP, 02h)
The Page Program (PP) instruction allows up to 256 bytes data to be programmed into memory in a single
operation. The destination of the memory to be programmed must be outside the protected memory area set by
the Block Protection (BP2, BP1, BP0) bits. A PP instruction which attempts to program into a page that is writeprotected will be ignored. Before the execution of PP instruction, the Write Enable Latch (WEL) must be enabled
through a Write Enable (WREN) instruction.
The PP instruction code, three address bytes and program data (1 to 256 bytes) are input via the Sl line.
Program operation will start immediately after the CE# is brought high, otherwise the PP instruction will not be
executed. The internal control logic automatically handles the programming voltages and timing. During a
program operation, all instructions will be ignored except the RDSR instruction. The progress or completion of
the program operation can be determined by reading the WIP bit in Status Register via a RDSR instruction. If
the WIP bit is “1”, the program operation is still in progress. If WIP bit is “0”, the program operation has
completed.
If more than 256 bytes data are sent to a device, the address counter rolls over within the same page, the
previously latched data are discarded, and the last 256 bytes are kept to be programmed into the page. The
starting byte can be anywhere within the page. When the end of the page is reached, the address will wrap
around to the beginning of the same page. If the data to be programmed are less than a full page, the data of all
other bytes on the same page will remain unchanged.
Note: A program operation can alter “1”s into “0”s, but an erase operation is required to change “0”s back to “1”s.
A byte cannot be reprogrammed without first erasing the whole sector or block.

8.8 QUAD INPUT PAGE PROGRAM OPERATION (PPQ, 32h/38h)
The Quad Input Page Program instruction allows up to 256 bytes data to be programmed into memory in a
single operation with four pins (IO0, IO1, IO2 and IO3). The destination of the memory to be programmed must
be outside the protected memory area set by the Block Protection (BP3, BP2, BP1, BP0) bits. A Quad Input
Page Program instruction which attempts to program into a page that is write-protected will be ignored. Before
the execution of Quad Input Page Program instruction, the QE bit in the status register must be set to “1” and
the Write Enable Latch (WEL) must be enabled through a Write Enable (WREN) instruction.
The Quad Input Page Program instruction code, three address bytes and program data (1 to 256 bytes) are
input via the four pins (IO0, IO1, IO2 and IO3). Program operation will start immediately after the CE# is brought
high, otherwise the Quad Input Page Program instruction will not be executed. The internal control logic
automatically handles the programming voltages and timing. During a program operation, all instructions will be
ignored except the RDSR instruction. The progress or completion of the program operation can be determined
by reading the WIP bit in Status Register via a RDSR instruction. If the WIP bit is “1”, the program operation is
still in progress. If WIP bit is “0”, the program operation has completed.
If more than 256 bytes data are sent to a device, the address counter rolls over within the same page, the
previously latched data are discarded, and the last 256 bytes data are kept to be programmed into the page.
The starting byte can be anywhere within the page. When the end of the page is reached, the address will wrap
around to the beginning of the same page. If the data to be programmed are less than a full page, the data of all
other bytes on the same page will remain unchanged.
Note: A program operation can alter “1”s into “0”s, but an erase operation is required to change “0”s back to “1”s.
A byte cannot be reprogrammed without first erasing the whole sector or block.

8.9 ERASE OPERATION
The memory array of the IS25LP128 is organized into uniform 4 Kbyte sectors or 32K/64 Kbyte uniform blocks
(a block consists of sixteen adjacent sectors).
Before a byte is reprogrammed, the sector or block that contains the byte must be erased (erasing sets bits to
“1”). In order to erase the device, there are three erase instructions available: Sector Erase (SER), Block Erase
(BER) and Chip Erase (CER). A sector erase operation allows any individual sector to be erased without
affecting the data in other sectors. A block erase operation erases any individual block. A chip erase operation
erases the whole memory array of a device. A sector erase, block erase, or chip erase operation can be
executed prior to any programming operation.

8.10 SECTOR ERASE OPERATION (SER, D7h/20h)
A Sector Erase (SER) instruction erases a 4 Kbyte sector before the execution of a SER instruction, the Write
Enable Latch (WEL) must be set via a Write Enable (WREN) instruction. The WEL bit is reset automatically after
the completion of sector an erase operation.
A SER instruction is entered, after CE# is pulled low to select the device and stays low during the entire
instruction sequence The SER instruction code, and three address bytes are input via SI. Erase operation will
start immediately after CE# is pulled high. The internal control logic automatically handles the erase voltage and
timing. Refer to Figure 8.12-8.13 for the Sector Erase Sequence.
During an erase operation, all instruction will be ignored except the Read Status Register (RDSR) instruction.
The progress or completion of the erase operation can be determined by reading the WIP bit in the Status
Register using a RDSR instruction. If the WIP bit is “1”, the erase operation is still in progress. If the WIP bit is
“0”, the erase operation has been completed.

8.20 PROGRAM/ERASE SUSPEND & RESUME
The device allows the interruption of Sector-Erase, Block-Erase or Page-Program operations to conduct other
operations. B0h command for suspend and 30h for resume will be used. (SPI/QPI all acceptable) Function
register bit2 (PSUS) and bit3 (ESUS) are used to check whether or not the device is in suspend mode.
Suspend to read ready timing: 100µs.
Resume to another suspend timing: 400µs (recommendation).
PROGRAM/ERASE SUSPEND DURING SECTOR-ERASE OR BLOCK-Erase (PERSUS 75h/B0h)
After erase suspend, WEL bit will be disabled, therefore only read related, resume and reset commands will be
accepted (03h, 0Bh, BBh, EBh, 05h, ABh, 30h, 9Fh, ABh, 90h, 4Bh, 00h, 66h, 99h, AFh, C0h).
To execute a Program/Erase Suspend operation, the host drives CE# low, sends the Program/Erase Suspend
command cycle (B0H), then drives CE# high. The Function register indicates that the erase has been
suspended by changing the ESUS bit from ‘0’ to ‘1,’ but the device will not accept another command until it is
ready. To determine when the device will accept a new command, poll the WIP bit in the Status register or wait
tSUS. When ESUS bit is issued, the Write Enable Latch (WEL) bit will be reset.
PROGRAM/ERASE SUSPEND DURING PAGE PROGRAMMING (PERSUS 75h/B0h)
Program suspend allows the interruption of all program operations.
After a program suspend command, WEL bit will be disabled, only read related, resume and reset command
can be accepted (03h, 0Bh, BBh, EBh, 05h, ABh, 30h, 9Fh, ABh, 90h, 4Bh, 00h, 66h, 99h, AFh, C0h).
To execute a Program/Erase Suspend operation, the host drives CE# low, sends the Program/Erase Suspend
command cycle (B0H), then drives CE# high. The Function register indicates that the programming has been
suspended by changing the PSUS bit from ‘0’ to ‘1,’ but the device will not accept another command until it is
ready. To determine when the device will accept a new command, poll the WIP bit in the Status register or wait
tSUS.
PROGRAM/ERASE RESUME (PERRSM 7A/30h)
Program/Erase Resume restarts a Program/Erase command that was suspended, and changes the suspend
status bit in the (ESUS or PSUS bits) back to ‘0’. To execute a Program/Erase Resume operation, the host
drives CE# low, sends the Program/Erase Resume command cycle (30H), then drives CE# high. A cycle is two
nibbles long, most significant nibble first. To determine if the internal, self-timed Write operation completed, poll
the WIP bit in the Status register, or wait the specified time tSE, tBE or tPP for Sector- Erase, Block-Erase, or
Page-Programming, respectively. The total write time before suspend and after resume will not exceed the
uninterrupted write times tSE, tBE or tPP.

8.21 DEEP POWER DOWN (DP, B9h)
The Deep Power-down (DP) instruction is for setting the device on the minimizing the power consumption (enter
into Power-Down mode), the standby current is reduced from Isb1 to Isb2). During the Power-down mode, the
device is not active and all Write/Program/Erase instructions are ignored. The instruction is initiated by driving
the CE# pin low and shifting the instruction code “B9h” as show in the figure 8.34. The CE# pin must be driven
high after the instruction has been latched. If this is not done the Power-Down will not be executed. After CE#
pin driven high, the power-down state will entered within the time duration of tDP. While in the power-down state
only the Release from Power-down / RDID instruction, which restores the device to normal operation, will be
recognized. All other instructions are ignored. This includes the Read Status Register instruction, which is
always available during normal operation. Ignoring all but one instruction makes the Power Down state a useful
condition for securing maximum write protection. It can support in SPI and QPI mode.

8.22 RELEASE DEEP POWER DOWN (RDPD, ABh)
The Release from Power-down /read Device ID instruction is a multi-purpose instruction. To release the device
from the power-down state Mode, the instruction is issued by driving the CE# pin low, shifting the instruction
code “ABh” and driving CE# high as shown in Figure 8.36, 8.37
Release from power-down will take the time duration of tRES1 before the device will resume normal operation
and other instructions are accepted. The CE# pin must remain high during the tRES1 time duration. If the
Release from Power-down / RDID instruction is issued while an Erase, Program or Write cycle is in process
(when WIP equals 1) the instruction is ignored and will not have any effects on the current cycle.

Read with “8/16/32/64-Byte Wrap Around”
The device is capable of burst read with wrap around in both SPI and QPI mode. The size of burst length is
configurable by using P0, P1, and P2 bits in READ register. P2 bit (Wrap enable) enables the burst mode
feature. P0 and P1 define the size of burst. Burst of 8, 16, 32, and 64 bytes are supported. In the default,
address increases by one up to whole array. By setting the burst length, the data being accessed can be limited
to the length of burst boundary inside of 256 byte page. The first output will be the data at the initial address
which is specified in the instruction. Following data will come out from the next address inside of burst boundary.
Once the address reaches the end of boundary, it will automatically move to the first address of the boundary.
CS# high will terminate the command.
For example, if burst length of 8 and initial address being applied is 0h, following byte output will be from
address 00h and continue to 01h,..,07h, 00h, 01h… until CS# terminates the operation. If burst length of 8 and
initial address being applied is FEh(254d), following byte output will be from address FEh and continue to FFh,
F8h, F9h, FAh, FBh, FCh, FDh, and repeat from FEh until CS# terminates the operation.
The command, “SET READ PARAMETERS OPERATION (C0h)”, is used to configure the Burst length. If the
following data input is one of “00h”,”01h”,”02h”, and ”03h”, the device will be in the default operation mode. It will
be continuous burst read of whole array. If the following data input is one of “04h”,”05h”,”06h”, and ”07h”, the
device will set the burst length as 8,16,32 and 64 respectively.
To exit the burst mode, another “C0h” command is necessary to set P2 to 0. Otherwise, the burst mode will be
retained until power down or reset operations. To change burst length, another “C0h” command should be
executed to set P0 and P1 (Detailed information in Table 6.7 Burst Length Data). All read commands operate in
burst mode once the READ register is set to enable burst mode.
Refer to Figures 8.38 and 8.39 for instruction sequence.

8.24 READ PRODUCT IDENTIFICATION (RDID, ABh)
The Release from Power-down /read Device ID instruction is a multi-purpose instruction. It can support both SPI
and QPI mode. The Read Product Identification (RDID) instruction is for reading out the old style of 8-bit
Electronic Signature, whose values are shown as table of ID Definitions.
The RDID instruction code is followed by three dummy bytes, each bit being latched-in on SI during the rising
SCK edge. Then the Device ID is shifted out on SO with the MSB first, each bit been shifted out during the
falling edge of SCK. The RDID instruction is ended by CE# going high. The Device ID (ID7-ID0) outputs
repeatedly if additional clock cycles are continuously sent on SCK while CE# is at low.

the devices. Refer to Table 8.3 Product Identification for manufacturer ID and device ID. The RDID instruction
code is followed by two dummy bytes and one byte address (A7~A0), each bit being latched-in on SI during the
rising edge of SCK. If one byte address is initially set to A0 = 0, then the manufacturer ID (9Dh) is shifted out on
SO with the MSB first followed by the device ID7- ID0. Each bit shifted out during the falling edge of SCK. If one
byte address is initially set to A0 = 1, then Device ID7-ID0 will be read first followed by the Manufacture ID (9Dh).
The manufacture and device ID can be read continuously alternating between the two until CE# is driven high.

8.28 READ SFDP OPERATION (RDSFDP, 5Ah)
The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the
functional and feature capabilities of serial Flash devices in a standard set of internal parameter tables. These
parameter tables can be interrogated by host system software to enable adjustments needed to accommodate
divergent features from multiple vendors. The concept is similar to the one found in the Introduction of JEDEC
Standard, JESD68 on CFI.
The sequence of issuing RDSFDP instruction is same as FAST_READ: CE# 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 CE# to high at any time during data out. Refer to ISSI’s Application note
for SFDP table. The data at the addresses that are not specified in SFDP table is undefined.

8.29 NO OPERATION (NOP, 00h)
The No Operation command only cancels a Reset Enable command. NOP has no impact on any other
command. It can use in the SPI and QPI mode.
To execute a NOP, the host drives CE# low, sends the NOP command cycle (00H), then drives CE# high.
8.30 SOFTWARE RESET (RESET-ENABLE (RSTEN, 66h) AND RESET (RST, 99h)
The Reset operation is used as a system (software) reset that puts the device in normal operating mode. This
operation consists of two commands: Reset-Enable (RSTEN) and Reset (RST).
The Reset operation requires the Reset-Enable command followed by the Reset command. Any command other
than the Reset command after the Reset-Enable command will disable the Reset-Enable.
Execute the CE# pin low  sends the Reset-Enable command (66h), and drives CE# high. Next, the host drives
CE# low again, sends the Reset command (99h), and drives CE# high.
A device reset during an active Program or Erase operation aborts the operation, which can cause the data of
the targeted address range to be corrupted or lost. Depending on the prior operation, the reset timing may vary.
Recovery from a Write operation requires more latency time than recovery from other operations.

8.34 INFORMATION ROW PROGRAM OPERATION (IRP, 62h)
The Information Row Program (IRP) instruction allows up to 1024 bytes, 4x256 bytes, data to be programmed
into memory in a single operation. Before the execution of PP instruction, the Write Enable Latch (WEL) must be
enabled through a Write Enable (WREN) instruction.
The IRP instruction code, three address bytes and program data (1 to 256 bytes) are input via the Sl line.
Program operation will start immediately after the CE# goes high, otherwise the IRP instruction will not be
executed. The internal control logic automatically handles the programming voltages and timing. During a
program operation, all instructions will be ignored except the RDSR instruction. The progress or completion of
the program operation can be determined by reading the WIP bit in Status Register via a RDSR instruction. If
the WIP bit is “1”, the program operation is still in progress. If WIP bit is “0”, the program operation has
completed.
If more than 1024 bytes data are sent to a device, the address counter rolls over within the same page. The
previously latched data are discarded and the last 1024 bytes data are kept to be programmed into the page.
The starting byte can be anywhere within the page. When the end of the page is reached, the address will wrap
around to the beginning of the same page. If the data to be programmed are less than a full page, the data of all
other bytes on the same page will remain unchanged.
Note: A program operation can alter “1”s into “0”s, but an erase operation is required to change “0”s back to “1”s.
A byte cannot be reprogrammed without first erasing the whole sector or block.

8.35 INFORMATION ROW READ OPERATION (IRRD, 68h)
The IRRD instruction is used to read memory data at up to a 133MHz clock.
The IRRD instruction code is followed by three address bytes (A23 - A0) and a dummy byte (8 clocks),
transmitted via the SI line, with each bit latched-in during the rising edge of SCK. Then the first data byte
addressed is shifted out on the SO line, with each bit shifted out at a maximum frequency fCT, during the falling
edge of SCK.
The address is automatically incremented after each byte of data is shifted out. When the highest address is
reached, the address counter will roll over to the 000000h address, allowing the entire memory to be read with a
single IRRD instruction. The IRRD instruction is terminated by driving CE# high (VIH). If a IRRD instruction is
issued while an Erase, Program or Write cycle is in process (WIP=1) the instruction is ignored and will not have
any effects on the current cycle

8.36 FAST READ DTR MODE OPERATION (FRDTR, 0DH)
The FRDTR 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 SCK, and data of each bit shifts out on both
rising and falling edge of SCK 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 FRDTR instruction. The address counter rolls over to 0 when the
highest address has been reached.
The sequence of issuing FRDTR instruction is: CE# goes low → sending FRDTR 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 FRDTR operation can use CE# to high at any time during data out. (Please refer to Figure 8.52)
While Program/Erase/Write Status Register cycle is in progress, FRDTR instruction is rejected without any impact on the Program/Erase/Write Status Register current cycle.

8.37 FAST READ DUAL IO DTR MODE OPERATION (FRDDTR, BDH)
The FRDDTR instruction enables Double Transfer Rate throughput on dual I/O of Serial Flash in read mode.
The address (interleave on dual I/O pins) is latched on both rising and falling edge of SCK, and data (interleave
on dual I/O pins) shift out on both rising and falling edge of SCK 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 FRDDTR instruction. The address counter rolls over to 0 when the
highest address has been reached. Once writing FRDDTR instruction, the following address/dummy/ data out
will perform as 4-bit instead of previous 1-bit.
The sequence of issuing FRDDTR instruction is: CE# goes low → sending FRDDTR 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
interleave on SIO1 & SIO0 (4-bit per clock) → to end FRDDTR operation can use CE# to high at any time during
data out (Please refer to Figure 8.53 for 2 x I/O Double Transfer Rate Read Mode Timing Waveform).
While Program/Erase/Write Status Register cycle is in progress, FRDDTR instruction is rejected without any
impact on the Program/Erase/Write Status Register current cycle.

8.38 FAST READ QUAD IO DTR MODE OPERATION (FRQDTR, EDH)
The FRQDTR 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 FRQDTR instruction. The address
(interleave on 4 I/O pins) is latched on both rising and falling edge of SCK, and data (interleave on 4 I/O pins)
shift out on both rising and falling edge of SCK 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 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 FRQDTR instruction. The address counter rolls over to 0 when the highest address has been reached.
Once writing FRQDTR instruction, the following address/dummy/data out will perform as 8-bit instead of
previous 1-bit.
The sequence of issuing FRQDTR instruction is: CE# goes low → sending FRQDTR 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 FRQDTR operation can use CE# to high at
any time during data out.
Another sequence of issuing enhanced mode of FRQDTR instruction especially useful in random access is:
CE# goes low → sending FRQDTR 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 CE# goes high → CE# goes low (eliminate 4 Read instruction) → 24-bit random access address
(Please refer to Figure 8.54 for 4x I/O Double Transfer Rate read enhance performance mode timing waveform).
While Program/Erase/Write Status Register cycle is in progress, FRQDTR instruction is rejected without any
impact on the Program/Erase/Write Status Register current cycle.

8.39 SECTOR LOCK/UNLOCK FUNCTIONS
SECTOR UNLOCK OPERATION (SECUNLOCK, 26h)
The Sector Unlock command allows the user to select a specific sector to allow program and erase operations.
This instruction is effective when the blocks are designated as write-protected through the BP0, BP1, BP2 and
BP3 bits in the status register. Only one sector can be enabled at any time. To enable a different sector, a
previously enabled sector must be disabled by executing a Sector Lock command. The instruction code is
followed by a 24-bit address specifying the target sector, but A0 through A11 are not decoded. The remaining
sectors within the same block remain in read-only mode.
In the Sector Unlock procedure, [A11:A0] need to be “0”, in order for the unlock procedure to be completed. The
chip will regard anything else as an illegal command.
