4 DEVICE OPERATION
SPI Mode
Standard SPI
The GD25LE80C features a serial peripheral interface on 4 signals bus: Serial Clock (SCLK), Chip Select (CS#), Serial
Data Input (SI) and Serial Data Output (SO). Both SPI bus mode 0 and 3 are supported. Input data is latched on the rising
edge of SCLK and data shifts out on the falling edge of SCLK.
Dual SPI
The GD25LE80C supports Dual SPI operation when using the “Dual Output Fast Read” and “Dual I/O Fast Read” (3BH and
BBH) commands. These commands allow data to be transferred to or from the device at twice the rate of the standard SPI.
When using the Dual SPI command the SI and SO pins become bidirectional I/O pins: IO0 and IO1.
Quad SPI
The GD25LE80C supports Quad SPI operation when using the “Quad Output Fast Read” (6BH),” Quad I/O Fast Read”
(EBH) commands. These commands allow data to be transferred to or from the device at four times the rate of the standard
SPI. When using the Quad SPI command the SI and SO pins become bidirectional I/O pins: IO0 and IO1, and WP# and
HOLD# pins become IO2 and IO3. Quad SPI commands require the non-volatile Quad Enable bit (QE) in Status Register
to be set.
Hold
The HOLD# signal goes low to stop any serial communications with the device, but doesn’t stop the operation of write status
register, programming, or erasing in progress.
The operation of HOLD, need CS# keep low, and starts on falling edge of the HOLD# signal, with SCLK signal being low (if
SCLK is not being low, HOLD operation will not start until SCLK being low). The HOLD condition ends on rising edge of
HOLD# signal with SCLK being low (If SCLK is not being low, HOLD operation will not end until SCLK being low).
The SO is high impedance, both SI and SCLK don’t care during the HOLD operation, if 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
then CS# must be at low.

5 Data Protection
The GD25LE80C provide the following data protection methods:
◆
Write Enable (WREN) command: The WREN command is set the Write Enable Latch bit (WEL). The WEL bit will
return to reset by the following situation:
-Power-Up
-Write Disable (WRDI)
-Write Status Register (WRSR)
-Page Program (PP)
-Sector Erase (SE) / Block Erase (BE) / Chip Erase (CE)
-Software reset (66H+99H)
◆
Software Protection Mode: The Block Protect (BP4, BP3, BP2, BP1, and BP0) bits define the section of the memory
array that can be read but not change.
◆
◆
Hardware Protection Mode: WP# goes low to protect the BP0~BP4 bits and SRP0~1 bits.
Deep Power-Down Mode: In Deep Power-Down Mode, all commands are ignored except the Release from Deep
Power-Down Mode command and software reset (66H+99H).

WIP
The status and control bits of the Status Register are as follows:
WIP bit
The Write in Progress (WIP) bit indicates whether the memory is busy in program/erase/write status register progress. When
WIP bit sets to 1, means the device is busy in program/erase/write status register progress, when WIP bit sets 0, means
the device is not in program/erase/write status register progress.
WEL bit
The Write Enable Latch (WEL) bit indicates the status of the internal Write Enable Latch. When set to 1 the internal Write
Enable Latch is set, when set to 0 the internal Write Enable Latch is reset and no Write Status Register, Program or Erase
command is accepted.
BP4, BP3, BP2, BP1, BP0 bits
The Block Protect (BP4, BP3, BP2, BP1, and BP0) bits are non-volatile. They define the size of the area to be software
protected against Program and Erase commands. These bits are written with the Write Status Register (WRSR) command.
When the Block Protect (BP4, BP3, BP2, BP1, BP0) bits are set to 1, the relevant memory area (as defined in
Table1).becomes protected against Page Program (PP), Sector Erase (SE) and Block Erase (BE) commands. The Block
Protect (BP4, BP3, BP2, BP1, and BP0) bits can be written provided that the Hardware Protected mode has not been set.
The Chip Erase (CE) command is executed, if the Block Protect (BP2, BP1, and BP0) bits are 0 and CMP=0 or the Block
Protect (BP2, BP1, and BP0) bits are 1 and CMP=1.
SRP1, SRP0 bits
The Status Register Protect (SRP1 and SRP0) bits are non-volatile Read/Write bits in the status register. The SRP bits
control the method of write protection: software protection, hardware protection, power supply lock-down or one time
programmable protection.

GD25LE80C
QE bit
The Quad Enable (QE) bit is a non-volatile Read/Write bit in the Status Register that allows Quad operation. When the QE
bit is set to 0 (Default) the WP# pin and HOLD# pin are enable. When the QE pin is set to 1, the Quad IO2 and IO3 pins are
enabled. (It is best to set the QE bit to 0 to avoid short issues if the WP# or HOLD# pin is tied directly to the power supply
or ground)
LB3, LB2, LB1 bits
The LB3, LB2, LB1 bits are non-volatile One Time Program (OTP) bits in Status Register (S13-S11) that provide the write
protect control and status to the Security Registers. The default state of LB3-LB1 are 0, the security registers are unlocked.
The LB3-LB1 bits can be set to 1 individually using the Write Register instruction. The LB3-LB1 bits are One Time
Programmable, once they are set to 1, the Security Registers will become read-only permanently.
CMP bit
The CMP bit is a non-volatile Read/Write bit in the Status Register (S14). It is used in conjunction with the BP4-BP0 bits to
provide more flexibility for the array protection. Please see the Status registers Memory Protection table for details. The
default setting is CMP=0.
SUS1, SUS2 bits
The SUS1 and SUS2 bits are read only bits in the status register (S15 and S10) that are set to 1 after executing an
Program/Erase Suspend (75H) command (The Erase Suspend will set the SUS1 to 1,and the Program Suspend will set the
SUS2 to 1). The SUS1 and SUS2 bits are cleared to 0 by Program/Erase Resume (7AH) command as well as a power-
down, power-up cycle.

7 COMMANDS DESCRIPTION
All commands, addresses and data are shifted in and out of the device, beginning with the most significant bit on the first
rising edge of SCLK after CS# is driven low. Then, the one-Byte command code must be shifted in to the device, with most
significant bit first on SI, and each bit is latched on the rising edges of SCLK.
See Table2, every command sequence starts with a one-Byte command code. Depending on the command, this might be
followed by address Bytes, or by data Bytes, or by both or none. CS# must be driven high after the last bit of the command
sequence has been completed. For the command of Read, Fast Read, Read Status Register or Release from Deep Power-
Down, and Read Device ID, the shifted-in command sequence is followed by a data-out sequence. All read instruction can
be completed after any bit of the data-out sequence is being shifted out, and then CS# must be driven high to return to
deselected status.
For the command of Page Program, Sector Erase, Block Erase, Chip Erase, Write Status Register, Write Enable, Write
Disable or Deep Power-Down command, CS# must be driven high exactly at a Byte boundary, otherwise the command is
rejected, and is not executed. That is CS# must be driven high when the number of clock pulses after CS# being driven low
is an exact multiple of eight. For Page Program, if at any time the input Byte is not a full Byte, nothing will happen and WEL
will not be reset.

7.1 Write Enable (WREN) (06H)
The Write Enable (WREN) command is for setting the Write Enable Latch (WEL) bit. The Write Enable Latch (WEL) bit must
be set prior to every Page Program (PP), Sector Erase (SE), Block Erase (BE), Chip Erase (CE), Write Status Register
(WRSR) and Erase/Program Security Registers command. The Write Enable (WREN) command sequence: CS# goes low
sending the Write Enable command CS# goes high.

7.3 Write Enable for Volatile Status Register (50H)
The non-volatile Status Register bits can also be written to as volatile bits. This gives more flexibility to change the system
configuration and memory protection schemes quickly without waiting for the typical non-volatile bit write cycles or affecting
the endurance of the Status Register non-volatile bits. The Write Enable for Volatile Status Register command must be
issued prior to a Write Status Register command and any other commands can't be inserted between them. Otherwise,
Write Enable for Volatile Status Register will be cleared. The Write Enable for Volatile Status Register command will not set
the Write Enable Latch bit, it is only valid for the Write Status Register command to change the volatile Status Register bit
values.

7.4 Read Status Register (RDSR) (05H or 35H)
The Read Status Register (RDSR) command is for reading the Status Register. The Status Register may be read at any
time, even while a Program, Erase or Write Status Register cycle is in progress. When one of these cycles is in progress, it
is recommended to check the Write in Progress (WIP) bit before sending a new command to the device. It is also possible
to read the Status Register continuously. For command code “05H”, the SO will output Status Register bits S7~S0. The
command code “35H”, the SO will output Status Register bits S15~S8.

7.5 Write Status Register (WRSR) (01H)
The Write Status Register (WRSR) command allows new values to be written to the Status Register. Before it can be
accepted, a Write Enable (WREN) command must previously have been executed. After the Write Enable (WREN)
command has been decoded and executed, the device sets the Write Enable Latch (WEL).
The Write Status Register (WRSR) command has no effect on S15, S10, S1 and S0 of the Status Register. CS# must be
driven high after the eighth or sixteen bit of the data Byte has been latched in. If not, the Write Status Register (WRSR)
command is not executed. If CS# is driven high after eighth bit of the data Byte, the CMP and QE and SRP1 bits will be
cleared to 0. As soon as CS# is driven high, the self-timed Write Status Register cycle (whose duration is tW) is initiated.
While the Write Status Register cycle is in progress, the Status Register may still be read to check the value of the Write In
Progress (WIP) bit. The Write In Progress (WIP) bit is 1 during the self-timed Write Status Register cycle, and is 0 when it
is completed. When the cycle is completed, the Write Enable Latch (WEL) is reset.
The Write Status Register (WRSR) command allows the user to change the values of the Block Protect (BP4, BP3, BP2,
BP1, and BP0) bits, to define the size of the area that is to be treated as read-only, as defined in Table1. The Write Status
Register (WRSR) command also allows the user to set or reset the Status Register Protect (SRP1 and SRP0) bits in
accordance with the Write Protect (WP#) signal. The Status Register Protect (SRP1 and SRP0) bits and Write Protect (WP#)
signal allow the device to be put in the Hardware Protected Mode. The Write Status Register (WRSR) command is not
executed once the Hardware Protected Mode is entered.

7.6 Read Data Bytes (READ) (03H)
The Read Data Bytes (READ) command is followed by a 3-Byte address (A23-A0), and each bit is latched-in on the rising
edge of SCLK. Then the memory content, at that address, is shifted out on SO, and each bit is shifted out, at a Max frequency
fR, on the falling edge of SCLK. The first Byte addressed can be at any location. The address is automatically incremented
to the next higher address after each Byte of data is shifted out. The whole memory can, therefore, be read with a single
Read Data Bytes (READ) command. Any Read Data Bytes (READ) command, while an Erase, Program or Write cycle is in
progress, is rejected without having any effects on the cycle that is in progress.

that address, is shifted out on SO, and each bit is shifted out, at a Max frequency fC, on the falling edge of SCLK. The first
Byte addressed can be at any location. The address is automatically incremented to the next higher address after each
Byte of data is shifted out.

7.10 Dual I/O Fast Read (BBH)
The Dual I/O Fast Read command is similar to the Dual Output Fast Read command but with the capability to input the 3-
Byte address (A23-0) and a “Continuous Read Mode” Byte 2-bit per clock by SI and SO, and each bit is latched in on the
rising edge of SCLK, then the memory contents are shifted out 2-bit per clock cycle from SI and SO. The command sequence
is shown below. The first Byte addressed can be at any location. The address is automatically incremented to the next
higher address after each Byte of data is shifted out.
Dual I/O Fast Read with “Continuous Read Mode”
The Dual I/O Fast Read command can further reduce command overhead through setting the “Continuous Read Mode” bits
(M7-0) after the input 3-Byte address (A23-A0). If the “Continuous Read Mode” bits (M5-4) = (1, 0), then the next Dual I/O
Fast Read command (after CS# is raised and then lowered) does not require the BBH command code. The command
sequence is shown below. If the “Continuous Read Mode” bits (M5-4) do not equal (1, 0), the next command requires the
command code, thus returning to normal operation. A “Continuous Read Mode” Reset command can be used to reset (M5-
4) before issuing normal command.

7.11 Quad I/O Fast Read (EBH)
The Quad I/O Fast Read command is similar to the Dual I/O Fast Read command but with the capability to input the 3-Byte
address (A23-0) and a “Continuous Read Mode” Byte and 4-dummy clock 4-bit per clock by IO0, IO1, IO3, IO4, and each
bit is latched in on the rising edge of SCLK, then the memory contents are shifted out 4-bit per clock cycle from IO0, IO1,
IO2, IO3. The command sequence is shown below. The first Byte addressed can be at any location. The address is
automatically incremented to the next higher address after each Byte of data is shifted out. The Quad Enable bit (QE) of
Status Register (S9) must be set to enable for the Quad I/O Fast read command.
Quad I/O Fast Read with “Continuous Read Mode”
The Quad I/O Fast Read command can further reduce command overhead through setting the “Continuous Read Mode”
bits (M7-0) after the input 3-Byte address (A23-A0). If the “Continuous Read Mode” bits (M5-4) = (1, 0), then the next Quad
I/O Fast Read command (after CS# is raised and then lowered) does not require the EBH command code. The command
sequence is shown below. If the “Continuous Read Mode” bits (M5-4) do not equal to (1, 0), the next command requires the
command code, thus returning to normal operation. A “Continuous Read Mode” Reset command can be used to reset (M5-
4) before issuing normal command.

Quad I/O Fast Read with “8/16/32/64-Byte Wrap Around” in Standard SPI mode
The Quad I/O Fast Read command can be used to access a specific portion within a page by issuing “Set Burst with Wrap”
(77H) commands prior to EBH. The “Set Burst with Wrap” (77H) command can either enable or disable the “Wrap Around”
feature for the following EBH commands. When “Wrap Around” is enabled, the data being accessed can be limited to either
an 8/16/32/64-Byte section of a 256-Byte page. The output data starts at the initial address specified in the command, once
it reaches the ending boundary of the 8/16/32/64-Byte section, the output will wrap around the beginning boundary
automatically until CS# is pulled high to terminate the command.
The Burst with Wrap feature allows applications that use cache to quickly fetch a critical address and then fill the cache
afterwards within a fixed length (8/16/32/64-Byte) of data without issuing multiple read commands. The “Set Burst with Wrap”
command allows three “Wrap Bits” W6-W4 to be set. The W4 bit is used to enable or disable the “Wrap Around” operation
while W6-W5 is used to specify the length of the wrap around section within a page.
7.12 Set Burst with Wrap (77H)
The Set Burst with Wrap command is used in conjunction with “Quad I/O Fast Read” command to access a fixed length of
8/16/32/64-Byte section within a 256-Byte page, in standard SPI mode.

normal read operation, another Set Burst with Wrap command should be issued to set W4=1.

7.13 Page Program (PP) (02H)
The Page Program (PP) command is for programming the memory. A Write Enable (WREN) command must previously
have been executed to set the Write Enable Latch (WEL) bit before sending the Page Program command.
The Page Program (PP) command is entered by driving CS# Low, followed by the command code, three address Bytes
and at least one data Byte on SI. If the 8 least significant address bits (A7-A0) are not all zero, all transmitted data that goes
beyond the end of the current page are programmed from the start address of the same page (from the address whose 8
least significant bits (A7-A0) are all zero). CS# must be driven low for the entire duration of the sequence. The Page Program
command sequence: CS# goes low sending Page Program command 3-Byte address on SI at least 1 Byte data
on SI CS# goes high. The command sequence is shown below. If more than 256 Bytes are sent to the device, previously
latched data are discarded and the last 256 data Bytes are guaranteed to be programmed correctly within the same page.
If less than 256 data Bytes are sent to device, they are correctly programmed at the requested addresses without having
any effects on the other Bytes of the same page. CS# must be driven high after the eighth bit of the last data Byte has been
latched in; otherwise the Page Program (PP) command is not executed.
As soon as CS# is driven high, the self-timed Page Program cycle (whose duration is tPP) is initiated. While the Page
Program cycle is in progress, the Status Register may be read to check the value of the Write in Progress (WIP) bit. The
Write in Progress (WIP) bit is 1 during the self-timed Page Program cycle, and is 0 when it is completed. At some unspecified
time before the cycle is completed, the Write Enable Latch (WEL) bit is reset.
A Page Program (PP) command applied to a page which is protected by the Block Protect (BP4, BP3, BP2, BP1, and BP0)
is not executed.

7.14 Quad Page Program (32H)
The Quad Page Program command is for programming the memory using four pins: IO0, IO1, IO2, and IO3. To use Quad
Page Program the Quad enable in status register Bit9 must be set (QE=1). A Write Enable (WREN) command must
previously have been executed to set the Write Enable Latch (WEL) bit before sending the Page Program command. The
quad Page Program command is entered by driving CS# Low, followed by the command code (32H), three address Bytes
and at least one data Byte on IO pins.
The command sequence is shown below. If more than 256 Bytes are sent to the device, previously latched data are
discarded and the last 256 data Bytes are guaranteed to be programmed correctly within the same page. If less than 256
data Bytes are sent to device, they are correctly programmed at the requested addresses without having any effects on the
other Bytes of the same page. CS# must be driven high after the eighth bit of the last data Byte has been latched in;
otherwise the Quad Page Program (PP) command is not executed.
As soon as CS# is driven high, the self-timed Quad Page Program cycle (whose duration is tPP) is initiated. While the Quad
Page Program cycle is in progress, the Status Register may be read to check the value of the Write In Progress (WIP) bit.
The Write in Progress (WIP) bit is 1 during the self-timed Quad Page Program cycle, and is 0 when it is completed. At some
unspecified time before the cycle is completed, the Write Enable Latch (WEL) bit is reset.
A Quad Page Program command applied to a page which is protected by the Block Protect (BP4, BP3, BP2, BP1, and BP0)
is not executed.

7.15 Sector Erase (SE) (20H)
The Sector Erase (SE) command is for erasing the all data of the chosen sector. A Write Enable (WREN) command must
previously have been executed to set the Write Enable Latch (WEL) bit. The Sector Erase (SE) command is entered by
driving CS# low, followed by the command code, and 3-address Byte on SI. Any address inside the sector is a valid address
for the Sector Erase (SE) command. CS# must be driven low for the entire duration of the sequence.
The Sector Erase command sequence: CS# goes low sending Sector Erase command 3-Byte address on SI CS#
goes high. The command sequence is shown below. CS# must be driven high after the eighth bit of the last address Byte
has been latched in; otherwise the Sector Erase (SE) command is not executed. As soon as CS# is driven high, the self-
timed Sector Erase cycle (whose duration is tSE) is initiated. While the Sector Erase cycle is in progress, the Status Register
may be read to check the value of the Write in Progress (WIP) bit. The Write in Progress (WIP) bit is 1 during the self-timed
Sector Erase cycle, and is 0 when it is completed. At some unspecified time before the cycle is completed, the Write Enable

7.19 Enable/Disable SO to Output RY/BY# (ESRY/DSRY) (70H/80H)
Besides SO pin is used to output data, it also can be used as the status pin of ready/busy. The ESRY command is for
outputting the ready/busy status to SO. When the device is in the process of power on, enter or exit deep power down
mode and erase/program, its status is busy, and the SO output 0. When the device is in the standby mode, the status of
device is ready, then SO output 1. The DSRY command is for resetting ESRY. The ready/busy status will not output to SO
after DSRY issued.
The Enable/Disable SO to Output RY/BY# command sequence: CS# goes low → sending ESRY command code → CS#
goes high. The command sequence is shown below. CS# must be driven high after the eighth bit of the command code
has been latched in; otherwise the Enable/Disable SO to Output RY/BY# command is not executed.

7.20 Deep Power-Down (DP) (B9H)
Executing the Deep Power-Down (DP) command is the only way to put the device in the lowest consumption mode (the
Deep Power-Down Mode). It can also be used as an extra software protection mechanism, while the device is not in active
use, since in this mode, the device ignores all Write, Program and Erase commands. Driving CS# high deselects the device,
and puts the device in the Standby Mode (if there is no internal cycle currently in progress). But this mode is not the Deep
Power-Down Mode. The Deep Power-Down Mode can only be entered by executing the Deep Power-Down (DP) command.
Once the device has entered the Deep Power-Down Mode, all commands are ignored except the Release from Deep
Power-Down and Read Device ID (RDI) command or software reset command. The Release from Deep Power-Down and
Read Device ID (RDI) command releases the device from Deep Power-Down mode, also allows the Device ID of the device
to be output on SO.
The Deep Power-Down Mode automatically stops at Power-Down, and the device always in the Standby Mode after Power-
Up.
The Deep Power-Down command sequence: CS# goes low sending Deep Power-Down command CS# goes high.
The command sequence is shown below. CS# must be driven high after the eighth bit of the command code has been
latched in; otherwise the Deep Power-Down (DP) command is not executed. As soon as CS# is driven high, it requires a
delay of tDP before the supply current is reduced to ICC2 and the Deep Power-Down Mode is entered. Any Deep Power-
Down (DP) command, while an Erase, Program or Write cycle is in progress, is rejected without having any effects on the
cycle that is in progress.

7.21 Release from Deep Power-Down and Read Device ID (RDI) (ABH)
The Release from Power-Down and Read Device ID command is a multi-purpose command. It can be used to release the
device from the Power-Down state or obtain the devices electronic identification (ID) number.
To release the device from the Power-Down state, the command is issued by driving the CS# pin low, shifting the
instruction code “ABH” and driving CS# high as shown in Figure 24. Release from Power-Down will take the time duration
of tRES1 (See AC Characteristics) before the device will resume normal operation and other command are accepted. The
CS# pin must remain high during the tRES1 time duration.
When used only to obtain the Device ID while not in the Power-Down state, the command is initiated by driving the CS#
pin low and shifting the instruction code “ABH” followed by 3-dummy Byte. The Device ID bits are then shifted out on the
falling edge of SCLK with most significant bit (MSB) first as shown in Figure 25. The Device ID value is listed in
Manufacturer and Device Identification table. The Device ID can be read continuously. The command is completed by
driving CS# high.
When used to release the device from the Power-Down state and obtain the Device ID, the command is the same as
previously described, and shown in Figure 25, except that after CS# is driven high it must remain high for a time
duration of tRES2 (See AC Characteristics). After this time duration the device will resume normal operation and other
command will be accepted. If the Release from Power-Down / Device ID command is issued while an Erase, Program or

7.24 Read Manufacture ID/ Device ID Quad I/O (94H)
The Read Manufacturer/Device ID Quad I/O command is an alternative to the Release from Power-Down / Device ID
command that provides both the JEDEC assigned Manufacturer ID and the specific Device ID by quad I/O.
The command is initiated by driving the CS# pin low and shifting the command code “94H” followed by a 24-bit address
(A23-A0) of 000000H. After which, the Manufacturer ID and the Device ID are shifted out on the falling edge of SCLK with
most significant bit (MSB) first as shown below. If the 24-bit address is initially set to 000001H, the Device ID will be read
first.

7.25 Read Identification (RDID) (9FH)
The Read Identification (RDID) command allows the 8-bit manufacturer identification to be read, followed by two Bytes of
device identification. The device identification indicates the memory type in the first Byte, and the memory capacity of the
device in the second Byte. The Read Identification (RDID) command while an Erase or Program cycle is in progress, is not
decoded, and has no effect on the cycle that is in progress. The Read Identification (RDID) command should not be issued
while the device is in Deep Power-Down Mode.
The device is first selected by driving CS# low. Then, the 8-bit command code for the command is shifted in. This is followed
by the 24-bit device identification, stored in the memory. Each bit is shifted out on the falling edge of Serial Clock. The
command sequence is shown in below. The Read Identification (RDID) command is terminated by driving CS# high at any
time during data output. When CS# is driven high, the device is in the Standby Mode. Once in the Standby Mode, the device
waits to be selected, so that it can receive, decode and execute commands.

7.27 Program/Erase Suspend (PES) (75H)
The Program/Erase Suspend command “75H”, allows the system to interrupt a page program or sector/block erase
operation and then read data from any other sector or block. The Write Status Register command (01H) and Erase/Program
Security Registers command (44H,42H) and Erase commands (20H, 52H, D8H, C7H, 60H) and Page Program command
(02H/32H) are not allowed during Program suspend. The Write Status Register command (01H) and Erase Security
Registers command (44H) and Erase commands (20H, 52H, D8H, C7H, 60H) are not allowed during Erase suspend.
Program/Erase Suspend is valid only during the page program or sector/block erase operation. A maximum of time of “tsus”
(See AC Characteristics) is required to suspend the program/erase operation.
The Program/Erase Suspend command will be accepted by the device only if the SUS2/SUS1 bit in the Status Register
equal to 0 and WIP bit equal to 1 while a Page Program or a Sector or Block Erase operation is on-going. If the SUS2/SUS1
bit equal to 1 or WIP bit equal to 0, the Suspend command will be ignored by the device. The WIP bit will be cleared form 1
to 0 within “tsus” and the SUS2/SUS1 bit will be set from 0 to 1 immediately after Program/Erase Suspend. A power-off
during the suspend period will reset the device and release the suspend state. The command sequence is show below.

7.28 Program/Erase Resume (PER) (7AH)
The Program/Erase Resume command must be written to resume the program or sector/block erase operation after a
Program/Erase Suspend command. The Program/Erase Resume command will be accepted by the device only if the
SUS2/SUS1 bit equal to 1 and the WIP bit equal to 0. After issued the SUS2/SUS1 bit in the status register will be cleared
from 1 to 0 immediately, the WIP bit will be set from 0 to 1 within 200ns and the Sector or Block will complete the erase
operation or the page will complete the program operation. The Program/Erase Resume command will be ignored unless a
Program/Erase Suspend is active. The command sequence is show below.

7.29 Erase Security Registers (44H)
The GD25LE80C provides three 512-Byte Security Registers which can be erased and programmed individually. These
registers may be used by the system manufacturers to store security and other important information separately from the
main memory array.
The Erase Security Registers command is similar to Sector/Block Erase command. A Write Enable (WREN) command must
previously have been executed to set the Write Enable Latch (WEL) bit.
The Erase Security Registers command sequence: CS# goes low sending Erase Security Registers command The
Erase Security Registers command sequence: CS# goes low sending Erase Security Registers command 3-Byte
address on SI CS# goes high. The command sequence is shown below. CS# must be driven high after the eighth bit of
the last address Byte has been latched in; otherwise the Erase Security Registers command is not executed. As soon as
CS# is driven high, the self-timed Erase Security Registers cycle (whose duration is tSE) is initiated. While the Erase Security
Registers cycle is in progress, the Status Register may be read to check the value of the Write in Progress (WIP) bit. The
Write in Progress (WIP) bit is 1 during the self-timed Erase Security Registers cycle, and is 0 when it is completed. At some
unspecified time before the cycle is completed, the Write Enable Latch (WEL) bit is reset. The Security Registers Lock Bit
(LB3-1) in the Status Register can be used to OTP protect the security registers. Once the LB bit is set to 1, the Security
Registers will be permanently locked; the Erase Security Registers command will be ignored.

7.30 Program Security Registers (42H)
The Program Security Registers command is similar to the Page Program command. Each security register contains four
pages content. A Write Enable (WREN) command must previously have been executed to set the Write Enable Latch (WEL)
bit before sending the Program Security Registers command. The Program Security Registers command is entered by
driving CS# Low, followed by the command code (42H), three address Bytes and at least one data Byte on SI. As soon as
CS# is driven high, the self-timed Program Security Registers cycle (whose duration is tPP) is initiated. While the Program
Security Registers cycle is in progress, the Status Register may be read to check the value of the Write in Progress (WIP)
bit. The Write in Progress (WIP) bit is 1 during the self-timed Program Security Registers cycle, and is 0 when it is completed.
At some unspecified time before the cycle is completed, the Write Enable Latch (WEL) bit is reset.
If the Security Registers Lock Bit (LB3-1) is set to 1, the Security Registers will be permanently locked. Program Security
Registers command will be ignored.

7.31 Read Security Registers (48H)
The Read Security Registers command is similar to Fast Read command. The command is followed by a 3-Byte address
(A23-A0) and a dummy Byte, and each bit is latched-in on the rising edge of SCLK. Then the memory content, at that
address, is shifted out on SO, and each bit is shifted out, at a Max frequency fC, on the falling edge of SCLK. The first Byte
addressed can be at any location. The address is automatically incremented to the next higher address after each Byte of
data is shifted out. Once the A8-A0 address reaches the last Byte of the register (Byte 1FFH), it will reset to 000H, the
command is completed by driving CS# high.

7.32 Enable Reset (66H) and Reset (99H)
If the Reset command is accepted, any on-going internal operation will be terminated and the device will return to its default
power-on state and lose all the current volatile settings, such as Volatile Status Register bits, Write Enable Latch status
(WEL), Program/Erase Suspend status, Read Parameter setting (P7-P0), Deep Power Down Mode, Continuous Read Mode
bit setting (M7-M0) and Wrap Bit Setting (W6-W4).
The “Enable Reset (66H)” and the “Reset (99H)” commands can be issued in either SPI mode. The “Reset (99H)” command
sequence as follow: CS# goes low Sending Enable Reset command CS# goes high CS# goes low Sending
Reset command CS# goes high. Once the Reset command is accepted by the device, the device will take approximately
tRST / tRST_E to reset. During this period, no command will be accepted. Data corruption may happen if there is an on-going
or suspended internal Erase or Program operation when Reset command sequence is accepted by the device. It is
recommended to check the BUSY bit and the SUS bit in Status Register before issuing the Reset command sequence.

7.34 Read Serial Flash Discoverable Parameter (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. SFDP is a standard
of JEDEC Standard No.216.
