4. DEVICE OPERATION
SPI Mode
Standard SPI
The GD25D10C/05C 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 GD25D10C/05C supports Dual Output operation when using the “Dual Output Fast Read” (3BH) 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 Output command the SI and SO pins become bidirectional I/O pins: IO0 and O1.

5. DATA PROTECTION
The GD25D10C/05C provides the following data protection methods:
Write Enable (WREN) command: The WREN command is set the Write Enable Latch bit (WEL). The WEL bit will
◆
reset to 0 in the following situations:
-Power-Up
-Write Disable (WRDI)
-Write Status Register (WRSR)
-Page Program (PP)
-Sector Erase (SE) / Block Erase (BE) / Chip Erase (CE)
Software Protection Mode: The Block Protect (BP2, BP1, BP0) bits define the section of the protected memory area
◆
which is read-only and unalterable.
◆
Hardware Protection Mode: WP# goes low to protect the BP0~BP2 bits and SRP bits.
◆
Deep Power-Down Mode: In Deep Power-Down Mode, all commands are ignored except the Release from Deep
Power-Down Mode command.
Write Inhibit Voltage (VWI): Device would reset automatically when VCC is below a certain threshold VWI.

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 is set to 1, it means the device is busy in program/erase/write status register progress. when WIP bit is cleared
to 0, it means the device is not in program/erase/write status register progress. The default value of WIP is 0.
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. The default value of WEL is 0.
BP2, BP1, BP0 bits.
The Block Protect (BP2, BP1, 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 (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 (BP2, BP1, 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, BP0) bits are all 0. The default value of BP2:0 are 0s.
SRP bit
The Status Register Protect (SRP) bit operates in conjunction with the Write Protect (WP#) signal. The Status Register
Write Protect (SRP) bit and Write Protect (WP#) signal set the device to the Hardware Protected mode. When the Status
Register Protect (SRP) bit is set to 1, and Write Protect (WP#) is driven Low. In this mode, the non-volatile bits of the Status
Register(SRP, BP2, BP1, BP0) become read-only bits and the Write Status Register (WRSR) instruction is not execution.
The default value of SRP is 0.

7. COMMANDS DESCRIPTION
All commands, addresses and data are shifted in and out of the device by the host system, with the most significant
bit first. On the first rising edge of SCLK after CS# is driven low, the one-byte command code must be shifted into the device,
with the most significant bit first on SI, and each bit being 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 data bytes, or dummy bytes. 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, which means the clock
pulse number should be an exact multiple of eight. Otherwise the command is rejected to executed. Especially for Page
Program command, if at any time the input end is not a completed byte, nothing will be written into the memory array, neither
would WEL bit be reset.

7.1. Write Enable (WREN) (06H)
The Write Enable (WREN) command is for setting the Write Enable Latch (WEL) bit to 1. The Write Enable Latch
(WEL) bit must be set prior to every Page Program (PP), Sector Erase (SE), Block Erase (BE), Chip Erase (CE) and Write
Status Register (WRSR) command.
The Write Enable (WREN) command sequence: CS# goes low → sending the Write Enable command → CS# goes
high.

7.3. Read Status Register (RDSR) (05H)
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.

7.4. Write Status Register (WRSR) (01H)
The Write Status Register (WRSR) instruction allows new values to be written to the Status Register. A Write Enable
(WREN) instruction must be executed previously to set the Write Enable Latch (WEL) bit, before it can be accepted.
The Write Status Register (WRSR) instruction is entered by driving Chip Select (CS#) Low, followed by the instruction
code and the data byte on Serial Data Input (DI).
The Write Status Register (WRSR) instruction has no effect on S6, S5, S1 and S0 of the Status Register. S6 and S5
are always read as 0. Chip Select (CS#) must be driven High after the eighth bit of the data byte has been latched in.
Otherwise, the Write Status Register (WRSR) instruction is not executed. As soon as Chip Select (CS#) is driven High, the
self-timed Write Status Register cycle (the duration is tW) is initiated. While the Write Status Register cycle is in progress,
reading Status Register to check the Write In Progress (WIP) bit is achievable.
The Write In Progress (WIP) bit is 1 during the self-timed Write Status Register cycle, and turn to 0 on the completion
of the Write Status Register. When the cycle is completed, the Write Enable Latch (WEL) is reset to 0.
The Write Status Register (WRSR) instruction allows the user to change the values of the Block Protect (BP2, BP1,
BP0) bits, which are utilized to define the size of the read-only area.
The Write Status Register (WRSR) instruction also allows the user to set or reset the Status Register Protect (SRP)
bit in accordance with the Write Protect (WP#) signal, by setting which the device can enter into Hardware Protected Mode
(HPM). The Write Status Register (WRSR) instruction is not executed once enter into the Hardware Protected Mode (HPM).

7.5. Read Data Bytes (READ) (03H)
The Read Data Bytes (READ) command is followed by a 3-byte address (A23-A0), and each bit being latched-in on
the rising edge of SCLK. Then the memory content, at that address, is shifted out on SO, and each bit being 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.

The Read Data Bytes at Higher Speed (Fast Read) command is for quickly reading data out. It is followed by a 3-byte
address (A23-A0) and a dummy byte, and each bit being latched-in on the rising edge of SCLK. Then the memory content,
at that address, is shifted out on SO, and each bit being 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

automatically incremented to the next higher address after each byte of data is shifted out.

7.8. 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 (A7A0) 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 in Figure8.
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 t PP) 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 is not executed when it is applied to a page protected by the Block Protect (BP2,
BP1, BP0).

7.9. Sector Erase (SE) (20H)
The Sector Erase (SE) command is for erasing the all data of the specific 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 in Figure9. 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 t SE) is initiated. While the Sector Erase cycle is in progress, the Status
Register is accessed 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 becomes 0 when it is completed. At some unspecified time before the cycle is completed,
the Write Enable Latch (WEL) bit is reset. A Sector Erase (SE) command applied to a sector which is protected by the Block
Protect (BP2, BP1, BP0) bit (see Table1) is not executed.

7.10. 32KB Block Erase (BE) (52H)
The 32KB Block Erase (BE) command is for erasing the all data of the chosen block. A Write Enable (WREN)
command must previously have been executed to set the Write Enable Latch (WEL) bit. The 32KB Block Erase (BE)
command is entered by driving CS# low, followed by the command code, and three address bytes on SI. Any address inside
the block is a valid address for the 32KB Block Erase (BE) command. CS# must be driven low for the entire duration of the
sequence.
The 32KB Block Erase command sequence: CS# goes low → sending 32KB Block Erase command → 3-byte address
on SI → CS# goes high. The command sequence is shown in Figure10. CS# must be driven high after the eighth bit of the
last address byte has been latched in; otherwise the 32KB Block Erase (BE) command is not executed. As soon as CS# is
driven high, the self-timed Block Erase cycle (whose duration is tBE) is initiated. While the Block Erase cycle is in progress,
the Status Register is accessed to check the value of the Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1
during the self-timed Block Erase cycle, and becomes 0 when it is completed. At some unspecified time before the cycle is
completed, the Write Enable Latch (WEL) bit is reset. A 32KB Block Erase (BE) command applied to a block which is

7.11. 64KB Block Erase (BE) (D8H)
The 64KB Block Erase (BE) command is for erasing the all data of the chosen block. A Write Enable (WREN)
command must previously have been executed to set the Write Enable Latch (WEL) bit. The 64KB Block Erase (BE)
command is entered by driving CS# low, followed by the command code, and three address bytes on SI. Any address inside
the block is a valid address for the 64KB Block Erase (BE) command. CS# must be driven low for the entire duration of the
sequence.
The 64KB Block Erase command sequence: CS# goes low → sending 64KB Block Erase command → 3-byte address
on SI → CS# goes high. The command sequence is shown in Figure11. CS# must be driven high after the eighth bit of the
last address byte has been latched in; otherwise the 64KB Block Erase (BE) command is not executed. As soon as CS# is
driven high, the self-timed Block Erase cycle (whose duration is tBE) is initiated. While the Block Erase cycle is in progress,
the Status Register is accessed to check the value of the Write In Progress (WIP) bit. The Write In Progress (WIP) bit is 1
during the self-timed Block Erase cycle, and becomes 0 when it is completed. At some unspecified time before the cycle is
completed, the Write Enable Latch (WEL) bit is reset. A 64KB Block Erase (BE) command applied to a block which is

7.12. Chip Erase (CE) (60/C7H)
The Chip Erase (CE) command is for erasing the all data of the chip. A Write Enable (WREN) command must
previously have been executed to set the Write Enable Latch (WEL) bit .The Chip Erase (CE) command is entered by driving
CS# Low, followed by the command code on Serial Data Input (SI). CS# must be driven Low for the entire duration of the
sequence.
The Chip Erase command sequence: CS# goes low → sending Chip Erase command → CS# goes high. The
command sequence is shown in Figure12. CS# must be driven high after the eighth bit of the command code has been
latched in, otherwise the Chip Erase command is not executed. As soon as CS# is driven high, the self-timed Chip Erase
cycle (whose duration is tCE) is initiated. While the Chip 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 Chip Erase 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 Chip Erase (CE) command is executed if the Block Protect (BP2, BP1, BP0) bits are all 0. The Chip Erase (CE)
command is not executed if any sector is under protection.

7.13. Deep Power-Down (DP) (B9H)
Executing the Deep Power-Down (DP) command is the only way to enter the lowest consumption mode (the Deep
Power-Down Mode). Unlike deselecting the device by driving CS# high, or entering into the Standby Mode (if there is no
internal cycle currently in progress), the Deep Power-Down Mode provides an extra software protection mechanism while
the device is not in active use. The only access to this mode is by executing the Deep Power-Down (DP) command. Since
in the Deep Power-Down mode, the device ignores all Write, Program and Erase commands. Once the device is in the
Deep Power-Down Mode, all commands are ignored except the Release from Deep Power-Down and Read Device ID (RDI)
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 is in the Standby Mode after PowerUp.

The Deep Power-Down command sequence: CS# goes low → sending Deep Power-Down command → CS# goes
high. The command sequence is shown in Figure13. 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 PowerDown (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.

7.14. Release from Deep Power-Down / Read Device ID (ABH)
The Release from Power-Down and Read Device ID command is a multi-purpose command, which can be used to
release the device from the Power-Down state or obtain the devices electronic identification (ID) number.
When used 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 Figure14. 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 keep 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 Figure15. The Device ID value for the
GD25D10C/05C 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 Figure15, 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 and Read Device ID command is issued while an Erase,
Program or Write cycle is in process (when WIP equal 1) the command is ignored and will not have any effects on the
current cycle.

7.15. Read Manufacture ID/ Device ID (REMS) (90H)
The Read Manufacturer/Device ID 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.
The command is initiated by driving the CS# pin low and shifting the command code “90H” followed by a 24-bit address
(A23-A0) of 000000H. After that, the Manufacturer ID and the Device ID are shifted out on the falling edge of SCLK with
most significant bit (MSB) first as shown in Figure16. If the 24-bit address is initially set to 000001H, the Device ID will be
read first.

7.16. 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. Any 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
21
3.3V Uniform Sector
Standard and Dual Serial Flash
GD25D10C/05C
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 Figure17. 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.

The Read Unique ID command accesses a factory-set read-only 128bit number that is unique to each device. The
Unique ID can be used in conjunction with user software methods to help prevent copying or cloning of a system.
The Read Unique ID command sequence: CS# goes low → sending Read Unique ID command → 3-Byte Address
