M25P10-A
Description
The M25P10-A is a 1 Mbit (128 Kbit x 8) serial Flash memory, with advanced write
protection mechanisms, accessed by a high speed SPI-compatible bus.
The memory can be programmed 1 to 256 bytes at a time, using the Page Program
instruction.
The memory is organized as 4 sectors, each containing 128 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 512 pages, or 131,072 bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,
using the Sector Erase instruction.

Signal descriptions
2.1
Serial Data output (Q)
M25P10-A
This output signal is used to transfer data serially out of the device. Data is shifted out on the
falling edge of Serial Clock (C).
2.2
Serial Data input (D)
This input signal is used to transfer data serially into the device. It receives instructions,
addresses, and the data to be programmed. Values are latched on the rising edge of Serial
Clock (C).
2.3
Serial Clock (C)
This input signal provides the timing of the serial interface. Instructions, addresses, or data
present at Serial Data input (D) are latched on the rising edge of Serial Clock (C). Data on
Serial Data output (Q) changes after the falling edge of Serial Clock (C).
2.4
Chip Select (S)
When this input signal is High, the device is deselected and Serial Data output (Q) is at high
impedance. Unless an internal Program, Erase or Write Status Register cycle is in progress,
the device will be in the Standby mode (this is not the Deep Power-down mode). Driving
Chip Select (S) Low selects the device, placing it in the Active Power mode.
After power-up, a falling edge on Chip Select (S) is required prior to the start of any
instruction.
2.5
Hold (HOLD)
The Hold (HOLD) signal is used to pause any serial communications with the device without
deselecting the device.
During the Hold condition, the Serial Data output (Q) is high impedance, and Serial Data
input (D) and Serial Clock (C) are Don’t care.
To start the Hold condition, the device must be selected, with Chip Select (S) driven Low.
2.6
Write Protect (W)
The main purpose of this input signal is to freeze the size of the area of memory that is
protected against program or erase instructions (as specified by the values in the BP1 and
BP0 bits of the Status Register).

SPI modes
SPI modes
These devices can be driven by a microcontroller with its SPI peripheral running in either of
the two following modes:
●
CPOL=0, CPHA=0
●
CPOL=1, CPHA=1
For these two modes, input data is latched in on the rising edge of Serial Clock (C), and
output data is available from the falling edge of Serial Clock (C).
The difference between the two modes, as shown in Figure 4, is the clock polarity when the
bus master is in Standby mode and not transferring data:

1. The Write Protect (W) and Hold (HOLD) signals should be driven, High or Low as appropriate.
Figure 3 shows an example of three devices connected to an MCU, on an SPI bus. Only one
device is selected at a time, so only one device drives the Serial Data output (Q) line at a
time, the other devices are high impedance. Resistors R (represented in Figure 3) ensure
that the M25P10-A is not selected if the Bus Master leaves the S line in the high impedance
state. As the Bus Master may enter a state where all inputs/outputs are in high impedance
at the same time (for example, when the Bus Master is reset), the clock line (C) must be
connected to an external pull-down resistor so that, when all inputs/outputs become high
impedance, the S line is pulled High while the C line is pulled Low (thus ensuring that S and
C do not become High at the same time, and so, that the tSHCH requirement is met). The
typical value of R is 100 kΩ, assuming that the time constant R*Cp (Cp = parasitic
capacitance of the bus line) is shorter than the time during which the Bus Master leaves the
SPI bus in high impedance.

SPI modes
M25P10-A
Example: Cp = 50 pF, that is R*Cp = 5 µs <=> the application must ensure that the Bus
Master never leaves the SPI bus in the high impedance state for a time period shorter than
5 µs.

Operating features
4.1
Page Programming
To program one data byte, two instructions are required: Write Enable (WREN), which is one
byte, and a Page Program (PP) sequence, which consists of four bytes plus data. This is
followed by the internal Program cycle (of duration tPP).
To spread this overhead, the Page Program (PP) instruction allows up to 256 bytes to be
programmed at a time (changing bits from 1 to 0), provided that they lie in consecutive
addresses on the same page of memory.
For optimized timings, it is recommended to use the Page Program (PP) instruction to
program all consecutive targeted bytes in a single sequence versus using several Page
Program (PP) sequences with each containing only a few bytes (see Page Program (PP)
and Table 16: Instruction times (device grade 6)).
4.2
Sector Erase and Bulk Erase
The Page Program (PP) instruction allows bits to be reset from 1 to 0. Before this can be
applied, the bytes of memory need to have been erased to all 1s (FFh). This can be
achieved either a sector at a time, using the Sector Erase (SE) instruction, or throughout the
entire memory, using the Bulk Erase (BE) instruction. This starts an internal Erase cycle (of
duration tSE or tBE).
The Erase instruction must be preceded by a Write Enable (WREN) instruction.
4.3
Polling during a Write, Program or Erase cycle
A further improvement in the time to Write Status Register (WRSR), Program (PP) or Erase
(SE or BE) can be achieved by not waiting for the worst case delay (tW, tPP, tSE, or tBE). The
Write In Progress (WIP) bit is provided in the Status Register so that the application program
can monitor its value, polling it to establish when the previous Write cycle, Program cycle or
Erase cycle is complete.
4.4
Active Power, Standby Power and Deep Power-down modes
When Chip Select (S) is Low, the device is selected, and in the Active Power mode.
When Chip Select (S) is High, the device is deselected, but could remain in the Active Power
mode until all internal cycles have completed (Program, Erase, Write Status Register). The
device then goes in to the Standby Power mode. The device consumption drops to ICC1.
The Deep Power-down mode is entered when the specific instruction (the Deep Powerdown (DP) instruction) is executed. The device consumption drops further to ICC2. The
device remains in this mode until another specific instruction (the Release from Deep
Power-down and Read Electronic Signature (RES) instruction) is executed.
While in the Deep Power-down mode, the device ignores all write, program and erase
instructions (see Deep Power-down (DP)). This can be used as an extra software protection
mechanism, when the device is not in active use, to protect the device from inadvertent
write, program or erase instructions.

Status Register
The Status Register contains a number of status and control bits, as shown in Table 6, that
can be read or set (as appropriate) by specific instructions. For a detailed description of the
Status Register bits, see Section 6.4: Read Status Register (RDSR).
4.6
Protection modes
The environments where non-volatile memory devices are used can be very noisy. No SPI
device can operate correctly in the presence of excessive noise. To help combat this, the
M25P10-A features the following data protection mechanisms:
●
Power On Reset and an internal timer (tPUW) can provide protection against inadvertent
changes while the power supply is outside the operating specification.
●
Program, Erase and Write Status Register instructions are checked that they consist of
a number of clock pulses that is a multiple of eight, before they are accepted for
execution.
●
All instructions that modify data must be preceded by a Write Enable (WREN)
instruction to set the Write Enable Latch (WEL) bit. This bit is returned to its reset state
by the following events:
–
12/51
Power-up
–
Write Disable (WRDI) instruction completion
–
Write Status Register (WRSR) instruction completion
–
Page Program (PP) instruction completion
–
Sector Erase (SE) instruction completion
–
Bulk Erase (BE) instruction completion
●
The Block Protect (BP1, BP0) bits allow part of the memory to be configured as readonly. This is the Software Protected mode (SPM).
●
The Write Protect (W) signal, in co-operation with the Status Register Write Disable
(SRWD) bit, allows the Block Protect (BP1, BP0) bits and Status Register Write Disable
(SRWD) bit to be write-protected. This is the Hardware Protected mode (HPM).
●
In addition to the low power consumption feature, the Deep Power-down mode offers
extra software protection, as all write, program and erase instructions are ignored.

Hold condition
The Hold (HOLD) signal is used to pause any serial communications with the device without
resetting the clocking sequence. However, taking this signal Low does not terminate any
Write Status Register, Program or Erase cycle that is currently in progress.
To enter the Hold condition, the device must be selected, with Chip Select (S) Low.
The Hold condition starts on the falling edge of the Hold (HOLD) signal, provided that this
coincides with Serial Clock (C) being Low (as shown in Figure 5).
The Hold condition ends on the rising edge of the Hold (HOLD) signal, provided that this
coincides with Serial Clock (C) being Low.
If the falling edge does not coincide with Serial Clock (C) being Low, the Hold condition
starts after Serial Clock (C) next goes Low. Similarly, if the rising edge does not coincide
with Serial Clock (C) being Low, the Hold condition ends after Serial Clock (C) next goes
Low. (This is shown in Figure 5).
During the Hold condition, the Serial Data output (Q) is high impedance, and Serial Data
input (D) and Serial Clock (C) are Don’t care.
Normally, the device is kept selected, with Chip Select (S) driven Low, for the whole duration
of the Hold condition. This is to ensure that the state of the internal logic remains unchanged
from the moment of entering the Hold condition.
If Chip Select (S) goes High while the device is in the Hold condition, this has the effect of
resetting the internal logic of the device. To restart communication with the device, it is
necessary to drive Hold (HOLD) High, and then to drive Chip Select (S) Low. This prevents
the device from going back to the Hold condition.

Instructions
All instructions, addresses and data are shifted in and out of the device, most significant bit
first.
Serial Data input (D) is sampled on the first rising edge of Serial Clock (C) after Chip Select
(S) is driven Low. Then, the one-byte instruction code must be shifted in to the device, most
significant bit first, on Serial Data input (D), each bit being latched on the rising edges of
Serial Clock (C).
The instruction set is listed in Table 4.
Every instruction sequence starts with a one-byte instruction code. Depending on the
instruction, this might be followed by address bytes, or by data bytes, or by both or none.
Chip Select (S) must be driven High after the last bit of the instruction sequence has been
shifted in.
In the case of a Read Data Bytes (READ), Read Data Bytes at higher speed (FAST_READ),
Read Identification (RDID), Read Status Register (RDSR) or Release from Deep Powerdown, and Read Electronic Signature (RES) instruction, the shifted-in instruction sequence
is followed by a data-out sequence. Chip Select (S) can be driven High after any bit of the
data-out sequence is being shifted out.
In the case of a Page Program (PP), Sector Erase (SE), Bulk Erase (BE), Write Status
Register (WRSR), Write Enable (WREN), Write Disable (WRDI) or Deep Power-down (DP)
instruction, Chip Select (S) must be driven High exactly at a byte boundary, otherwise the
instruction is rejected, and is not executed. That is, Chip Select (S) must driven High when
the number of clock pulses after Chip Select (S) being driven Low is an exact multiple of
eight.
All attempts to access the memory array during a Write Status Register cycle, Program
cycle or Erase cycle are ignored, and the internal Write Status Register cycle, Program
cycle or Erase cycle continues unaffected.

Read Identification (RDID)
The Read Identification (RDID) instruction is available in products with process technology
code X and Y.
The Read Identification (RDID) instruction allows the 8-bit manufacturer identification to be
read, followed by two bytes of device identification. The manufacturer identification is
assigned by JEDEC, and has the value 20h for Numonyx. The device identification is
assigned by the device manufacturer, and indicates the memory type in the first byte (20h),
and the memory capacity of the device in the second byte (11h).
Any Read Identification (RDID) instruction 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) instruction should not be issued while the device is in Deep
Power-down mode.
The device is first selected by driving Chip Select (S) Low. Then, the 8-bit instruction code
for the instruction is shifted in. This is followed by the 24-bit device identification, stored in
the memory, being shifted out on Serial Data output (Q), each bit being shifted out during
the falling edge of Serial Clock (C).
The instruction sequence is shown in Figure 9.
The Read Identification (RDID) instruction is terminated by driving Chip Select (S) High at
any time during data output.
When Chip Select (S) is driven High, the device is put in the Standby Power mode. Once in
the Standby Power mode, the device waits to be selected, so that it can receive, decode and
execute instructions.

Read Status Register (RDSR)
The Read Status Register (RDSR) instruction allows the Status Register to be read. 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 instruction to the device. It is
also possible to read the Status Register continuously, as shown in Figure 10.

The status and control bits of the Status Register are as follows:
6.4.1
WIP bit
The Write In Progress (WIP) bit indicates whether the memory is busy with a Write Status
Register, Program or Erase cycle. When set to ‘1’, such a cycle is in progress, when reset to
‘0’ no such cycle is in progress.
6.4.2
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 instruction is
accepted.
6.4.3
BP1, BP0 bits
The Block Protect (BP1, BP0) bits are non-volatile. They define the size of the area to be
software protected against program and erase instructions. These bits are written with the
Write Status Register (WRSR) instruction. When one or both of the Block Protect (BP1,
BP0) bits is set to ‘1’, the relevant memory area (as defined in Table 2) becomes protected
against Page Program (PP) and Sector Erase (SE) instructions. The Block Protect (BP1,
BP0) bits can be written provided that the Hardware Protected mode has not been set. The
Bulk Erase (BE) instruction is executed if, and only if, both Block Protect (BP1, BP0) bits are
0.
6.4.4
SRWD bit
The Status Register Write Disable (SRWD) bit is operated in conjunction with the Write
Protect (W) signal. The Status Register Write Disable (SRWD) bit and Write Protect (W)
signal allow the device to be put in the Hardware Protected mode (when the Status Register
Write Disable (SRWD) bit is set to ‘1’, and Write Protect (W) is driven Low). In this mode, the

non-volatile bits of the Status Register (SRWD, BP1, BP0) become read-only bits and the

Write Status Register (WRSR)
The Write Status Register (WRSR) instruction allows new values to be written to the Status
Register. Before it can be accepted, a Write Enable (WREN) instruction must previously
have been executed. After the Write Enable (WREN) instruction has been decoded and
executed, the device sets the Write Enable Latch (WEL).
The Write Status Register (WRSR) instruction is entered by driving Chip Select (S) Low,
followed by the instruction code and the data byte on Serial Data input (D).
The instruction sequence is shown in Figure 11.
The Write Status Register (WRSR) instruction has no effect on b6, b5, b4, b1 and b0 of the
Status Register. b6, b5 and b4 are always read as 0.
Chip Select (S) must be driven High after the eighth bit of the data byte has been latched in.
If not, the Write Status Register (WRSR) instruction is not executed. As soon as Chip Select
(S) 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. At
some unspecified time before the cycle is completed, the Write Enable Latch (WEL) is reset.
The Write Status Register (WRSR) instruction allows the user to change the values of the
Block Protect (BP1, BP0) bits, to define the size of the area that is to be treated as readonly, as defined in Table 2. The Write Status Register (WRSR) instruction also allows the
user to set or reset the Status Register Write Disable (SRWD) bit in accordance with the
Write Protect (W) signal. The Status Register Write Disable (SRWD) bit and Write Protect
(W) signal allow the device to be put in the Hardware Protected mode (HPM). The Write
Status Register (WRSR) instruction is not executed once the Hardware Protected mode
(HPM) is entered.
The protection features of the device are summarized in Table 7.
When the Status Register Write Disable (SRWD) bit of the Status Register is 0 (its initial
delivery state), it is possible to write to the Status Register provided that the Write Enable
Latch (WEL) bit has previously been set by a Write Enable (WREN) instruction, regardless
of the whether Write Protect (W) is driven High or Low.
When the Status Register Write Disable (SRWD) bit of the Status Register is set to ‘1’, two
cases need to be considered, depending on the state of Write Protect (W):
22/51
●
If Write Protect (W) is driven High, it is possible to write to the Status Register provided
that the Write Enable Latch (WEL) bit has previously been set by a Write Enable
(WREN) instruction
●
If Write Protect (W) is driven Low, it is not possible to write to the Status Register even
if the Write Enable Latch (WEL) bit has previously been set by a Write Enable (WREN)
instruction. (Attempts to write to the Status Register are rejected, and are not accepted
for execution). As a consequence, all the data bytes in the memory area that are
software protected (SPM) by the Block Protect (BP1, BP0) bits of the Status Register,
are also hardware protected against data modification.
M25P10-A
Instructions
Regardless of the order of the two events, the Hardware Protected mode (HPM) can be
entered:
●
by setting the Status Register Write Disable (SRWD) bit after driving Write Protect (W)
Low
●
or by driving Write Protect (W) Low after setting the Status Register Write Disable
(SRWD) bit.
The only way to exit the Hardware Protected mode (HPM) once entered is to pull Write
Protect (W) High.
If Write Protect (W) is permanently tied High, the Hardware Protected mode (HPM) can
never be activated, and only the Software Protected mode (SPM), using the Block Protect
(BP1, BP0) bits of the Status Register, can be used.

Read Data Bytes (READ)
The device is first selected by driving Chip Select (S) Low. The instruction code for the Read
Data Bytes (READ) instruction is followed by a 3-byte address (A23-A0), each bit being
latched-in during the rising edge of Serial Clock (C). Then the memory contents, at that
address, is shifted out on Serial Data output (Q), each bit being shifted out, at a maximum
frequency fR, during the falling edge of Serial Clock (C).
The instruction sequence is shown in Figure 12.
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) instruction. When the highest
address is reached, the address counter rolls over to 000000h, allowing the read sequence
to be continued indefinitely.
The Read Data Bytes (READ) instruction is terminated by driving Chip Select (S) High. Chip
Select (S) can be driven High at any time during data output. Any Read Data Bytes (READ)
instruction, while an Erase, Program or Write cycle is in progress, is rejected without having
any effects on the cycle that is in progress.

Read Data Bytes at Higher Speed (FAST_READ)
The device is first selected by driving Chip Select (S) Low. The instruction code for the Read
Data Bytes at Higher Speed (FAST_READ) instruction is followed by a 3-byte address (A23A0) and a dummy byte, each bit being latched-in during the rising edge of Serial Clock (C).
Then the memory contents, at that address, is shifted out on Serial Data output (Q), each bit
being shifted out, at a maximum frequency fC, during the falling edge of Serial Clock (C).
The instruction sequence is shown in Figure 13.
The first byte addressed can be at any location. The address is automatically incremented

The Read Data Bytes at Higher Speed (FAST_READ) instruction is terminated by driving
Chip Select (S) High. Chip Select (S) can be driven High at any time during data output. Any

Page Program (PP)
The Page Program (PP) instruction allows bytes to be programmed in the memory
(changing bits from 1 to 0). Before it can be accepted, a Write Enable (WREN) instruction
must previously have been executed. After the Write Enable (WREN) instruction has been
decoded, the device sets the Write Enable Latch (WEL).
The Page Program (PP) instruction is entered by driving Chip Select (S) Low, followed by
the instruction code, three address bytes and at least one data byte on Serial Data input (D).
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). Chip Select (S)
must be driven Low for the entire duration of the sequence.
The instruction sequence is shown in Figure 14.
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.
For optimized timings, it is recommended to use the Page Program (PP) instruction to
program all consecutive targeted bytes in a single sequence versus using several Page
Program (PP) sequences with each containing only a few bytes (see Table 16: Instruction
times (device grade 6)).
Chip Select (S) must be driven High after the eighth bit of the last data byte has been
latched in, otherwise the Page Program (PP) instruction is not executed.
As soon as Chip Select (S) 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) instruction applied to a page which is protected by the Block Protect
(BP1, BP0) bits (see Table 3 and Table 2) is not executed.

Sector Erase (SE)
The Sector Erase (SE) instruction sets to ‘1’ (FFh) all bits inside the chosen sector. Before it
can be accepted, a Write Enable (WREN) instruction must previously have been executed.
After the Write Enable (WREN) instruction has been decoded, the device sets the Write
Enable Latch (WEL).
The Sector Erase (SE) instruction is entered by driving Chip Select (S) Low, followed by the
instruction code, and three address bytes on Serial Data input (D). Any address inside the
sector (see Table 3) is a valid address for the Sector Erase (SE) instruction. Chip Select (S)
must be driven Low for the entire duration of the sequence.
The instruction sequence is shown in Figure 15.
Chip Select (S) must be driven High after the eighth bit of the last address byte has been
latched in, otherwise the Sector Erase (SE) instruction is not executed. As soon as Chip
Select (S) 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 Latch (WEL) bit is reset.
A Sector Erase (SE) instruction applied to a page which is protected by the Block Protect
(BP1, BP0) bits (see Table 3 and Table 2) is not executed.

Bulk Erase (BE)
The Bulk Erase (BE) instruction sets all bits to ‘1’ (FFh). Before it can be accepted, a Write
Enable (WREN) instruction must previously have been executed. After the Write Enable
(WREN) instruction has been decoded, the device sets the Write Enable Latch (WEL).
The Bulk Erase (BE) instruction is entered by driving Chip Select (S) Low, followed by the
instruction code on Serial Data input (D). Chip Select (S) must be driven Low for the entire
duration of the sequence.
The instruction sequence is shown in Figure 16.
Chip Select (S) must be driven High after the eighth bit of the instruction code has been
latched in, otherwise the Bulk Erase instruction is not executed. As soon as Chip Select (S)
is driven High, the self-timed Bulk Erase cycle (whose duration is tBE) is initiated. While the
Bulk 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 Bulk
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 Bulk Erase (BE) instruction is executed only if both Block Protect (BP1, BP0) bits are 0.
The Bulk Erase (BE) instruction is ignored if one, or more, sectors are protected.

Deep Power-down (DP)
Executing the Deep Power-down (DP) instruction is the only way to put the device in the
lowest consumption mode (the Deep Power-down mode). It can also be used as a software
protection mechanism, while the device is not in active use, as in this mode, the device
ignores all write, program and erase instructions.
Driving Chip Select (S) 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 Powerdown mode. The Deep Power-down mode can only be entered by executing the Deep
Power-down (DP) instruction, to reduce the standby current (from ICC1 to ICC2, as specified
in Table 14).
To take the device out of Deep Power-down mode, the Release from Deep Power-down and
Read Electronic Signature (RES) instruction must be issued. No other instruction must be
issued while the device is in Deep Power-down mode.
The Release from Deep Power-down, and Read Electronic Signature (RES) instruction and
the Read Identification (RDID) instruction also allow the electronic signature of the device to
be output on Serial Data output (Q).
The Deep Power-down mode automatically stops at power-down, and the device always
powers-up in the Standby mode.
The Deep Power-down (DP) instruction is entered by driving Chip Select (S) Low, followed
by the instruction code on Serial Data input (D). Chip Select (S) must be driven Low for the
entire duration of the sequence.
The instruction sequence is shown in Figure 17.
Chip Select (S) must be driven High after the eighth bit of the instruction code has been
latched in, otherwise the Deep Power-down (DP) instruction is not executed. As soon as
Chip Select (S) 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) instruction, while an Erase, Program or Write cycle is in
progress, is rejected without having any effects on the cycle that is in progress.

Release from Deep Power-down and Read Electronic
Signature (RES)
To take the device out of Deep Power-down mode, the Release from Deep Power-down and
Read Electronic Signature (RES) instruction must be issued. No other instruction must be
issued while the device is in Deep Power-down mode.
The instruction can also be used to read, on Serial Data output (Q), the 8-bit electronic
signature, whose value for the M25P10-A is 10h.
Except while an Erase, Program or Write Status Register cycle is in progress, the Release
from Deep Power-down and Read Electronic Signature (RES) instruction always provides
access to the 8-bit electronic signature of the device, and can be applied even if the Deep
Power-down mode has not been entered.
Any release from Deep Power-down and Read Electronic Signature (RES) instruction while
an Erase, Program or Write Status Register cycle is in progress, is not decoded, and has no
effect on the cycle that is in progress.
The device is first selected by driving Chip Select (S) Low. The instruction code is followed
by 3 dummy bytes, each bit being latched-in on Serial Data input (D) during the rising edge
of Serial Clock (C). Then, the 8-bit electronic signature, stored in the memory, is shifted out
on Serial Data output (Q), each bit being shifted out during the falling edge of Serial Clock
(C).
The instruction sequence is shown in Figure 18.
The Release from Deep Power-down and Read Electronic Signature (RES) instruction is
terminated by driving Chip Select (S) High after the electronic signature has been read at
least once. Sending additional clock cycles on Serial Clock (C), while Chip Select (S) is
driven Low, cause the electronic signature to be output repeatedly.
When Chip Select (S) is driven High, the device is put in the Standby Power mode. If the
device was not previously in the Deep Power-down mode, the transition to the Standby
Power mode is immediate. If the device was previously in the Deep Power-down mode,
though, the transition to the Standby Power mode is delayed by tRES2, and Chip Select (S)
must remain High for at least tRES2(max), as specified in Table 18. Once in the Standby
Power mode, the device waits to be selected, so that it can receive, decode and execute
instructions.
Driving Chip Select (S) High after the 8-bit instruction byte has been received by the device,
but before the whole of the 8-bit electronic signature has been transmitted for the first time
(as shown in Figure 19), still ensures that the device is put into Standby Power mode. If the
device was not previously in the Deep Power-down mode, the transition to the Standby
Power mode is immediate. If the device was previously in the Deep Power-down mode,
though, the transition to the Standby Power mode is delayed by tRES1, and Chip Select (S)
must remain High for at least tRES1(max), as specified in Table 18. Once in the Standby
Power mode, the device waits to be selected, so that it can receive, decode and execute
instructions.

Power-up and power-down
Power-up and power-down
At power-up and power-down, the device must not be selected (that is Chip Select (S) must
follow the voltage applied on VCC) until VCC reaches the correct value:
●
VCC(min) at power-up, and then for a further delay of tVSL
●
VSS at power-down
A safe configuration is provided in Section 3: SPI modes.
To avoid data corruption and inadvertent write operations during power-up, a Power On
Reset (POR) circuit is included. The logic inside the device is held reset while VCC is less
than the Power On Reset (POR) threshold voltage, VWI – all operations are disabled, and
the device does not respond to any instruction.
Moreover, the device ignores all Write Enable (WREN), Page Program (PP), Sector Erase
(SE), Bulk Erase (BE) and Write Status Register (WRSR) instructions until a time delay of
tPUW has elapsed after the moment that VCC rises above the VWI threshold. However, the
correct operation of the device is not guaranteed if, by this time, VCC is still below VCC(min).
No Write Status Register, Program or Erase instructions should be sent until the later of:
●
tPUW after VCC passed the VWI threshold
●
tVSL after VCC passed the VCC(min) level
These values are specified in Table 8.
If the delay, tVSL, has elapsed, after VCC has risen above VCC(min), the device can be
selected for read instructions even if the tPUW delay is not yet fully elapsed.
At power-up, the device is in the following state:
●
The device is in the Standby mode (not the Deep Power-down mode).
●
The Write Enable Latch (WEL) bit is reset.
●
The Write In Progress (WIP) bit is reset.
Normal precautions must be taken for supply rail decoupling, to stabilize the VCC supply.
Each device in a system should have the VCC rail decoupled by a suitable capacitor close to
the package pins. (Generally, this capacitor is of the order of 0.1 µF).
At power-down, when VCC drops from the operating voltage, to below the Power On Reset
(POR) threshold voltage, VWI, all operations are disabled and the device does not respond
to any instruction (the designer needs to be aware that if a power-down occurs while a
Write, Program or Erase cycle is in progress, some data corruption can result).
