2 Signal descriptions

2.1 Serial Data output (Q)

This output signal is used to tr ansf er data serially out of the de vice . 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 progr ess,

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 se rial communications with the de vice 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 th is inp ut sig nal is to freeze the size of the area of mem ory that is

protected against program or erase instructions (as specified by the values in the BP1 and

BP0 bits of the Status Register).

M25P10-A SPI modes

9/51

3 SPI modes

These devices can be driven by a microcontroller with its SPI peripheral running in either of

the two follo wing 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 , a s shown in Figure 4, is the clock polarity when the

bus mast er is in Standby mod e and not transferring data:

●C remains at 0 for (CPOL=0, CPHA=0)

●C remains at 1 for (CPOL=1, CPHA=1)

Figure 3. Bus mas t er an d memory devices on the SPI bus

1. The Write Protect (W) and Hold (HOLD) signals should be driven, High or Low as appropriate.

Figure 3 shows a n examp le of three de vices connected t o 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 selecte d if the Bus Master lea ves the S line in the high imp edance

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 Lo w ( thus ensuring that S a nd

C do not become High at the same time , and so, that the tSHCH requirement is met). The

typical v alue of R is 100 kΩ, assumin g that the tim e co nst an t R*Cp (Cp = parasitic

capacitance of the bus line) is shorter th an the ti me during which the Bus Mast er leaves the

SPI bus in high impe dance.

M25P10-A Operating features

4 Operating features

4.1 Page Programming

To prog ram one data b yte, two in structions are required: Write Enab le (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

Progr am (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

achie v ed either a se ctor 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 cy cle

A further improvement in the time to Write Status Regi ster (WRSR) , Prog r am (PP) or Era se

(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 pro vided in the Status Register so t hat the application progr am

can monitor its v alue , polling it to establish when the previous Write cycle, Prog r am 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 sele cted, and in the Active Power mode.

When Chip Select (S) is High, the de vice is deselected, b ut could remain in the Activ e 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 P ower-

down (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

Pow er-down and Read Electronic Signature (RES) instruction) is execu ted.

While in the Deep Power-down mode, the device ignores all write, program an d erase

instructions (see Deep P o w er-do wn (DP)). This can b e used as an e x tra softw are protection

mechanism, when th e device is not in active use, to protect the device from inadvertent

write, program or erase instructions.

4.5 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) b y sp ecific inst ructions. For a detailed description of the

Status Register bi ts, see Section 6.4: Read Status Register (R DSR).

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 e xcessive noise. To help combat this, the

M25P10-A features the following data protection mechanisms:

●P ow er On Reset and an internal timer (tPUW) can pro vide protection against inadvertent

changes while the power supply is outside the operating specification.

●Progr am, Er ase and Write Status Regist er instructions are chec ked that the y consist of

a number of clock pulses that is a multiple of eight, before they are accepted for

execution.

●All instructions that modify data m ust be preceded by a Write Enab le (WREN)

instruction to set the Write Enab le Latch (WEL) bit. This bit is retu rned to its rese t st ate

by the following events:

–Power-up

– Write Disable (WRDI) instruction completion

– Write Status Register (WRSR) instruction completion

– Page Program (PP) instruction completion

– Sector Erase ( SE) instruction co mpletion

– Bulk Erase (BE) instruction completion

●The Block Protect (BP1, BP0) bits allow part of the memory to be configured as read-

only. This is the Software Prote cted 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.

M25P10-A Operating features

4.7 Hold condition

The Hold (HOLD) signal is used to pause any se rial communications with the de vice without

resetting the clocking sequence. However, taking this signal Low do es not terminate any

Write Status Register, Program or Erase cycle that is currently in progress.

To enter th e 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 de vice is ke pt selected, with Chip Select (S) driv en Lo w, f or the whole d uration

of the Hold conditi on. 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.

6 Instructions

All instruct ion s, addresses and dat a 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 ) aft er Ch ip Se lect

(S) is drive n L ow. Then, the one-byte instruction code m ust be shif ted in to t he 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 byt es, 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 be en

shifted in.

In the case of a Read Data Bytes (READ), Rea d Data Bytes at higher speed (FAST_READ),

Read Identification (RDID), Read Status Register (RDSR) or Release from Deep Power-

down, an d 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 se quence is being shifted out.

In the case of a Page Program (PP), Sector Erase (SE), Bulk Erase (BE), Wr ite Status

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.

6.3 Read Identification (RDID)

The Read Identification (RDID) instruction is availab le 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 b y JEDEC, and has the v alue 20h f or STMicroe lectronics. T he de vice identification

is assigned b y 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 Id entification (RDID) instruction while an Erase or Pr ogram 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 instructio n 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 Standb y Power mode , the device w aits to be select ed, so that it can receiv e , decode and

execute instructions.

6.4 Read Status Register (RDSR)

The Read Status Register (RDSR) instruction allows the Status Register to be read. Th e

Status Register may be read at any time, ev en while a Program, Erase or Write Status

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 show n 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

‘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 are a 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 e x ecut ed if , and only if , both Block Prote ct (BP1, BP0) bits are

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 (SR WD) bit is set to ‘1’, and Write Protect (W) is driv en Lo w). In this mode , the

6.5 Write Status Register (WRSR)

The Write Status Register (WRSR) instruction allows new values to be written to the Status

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 driv en Hig h after the eighth bit of the d ata b yte has bee n latched in.

If not, the Write Status Register ( WRSR) instruction is not e x e cuted. As soon as Chip Sele ct

(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 bef ore the cycle is completed, the Write Enable Latch (WEL) is reset.

The Write Status Register (WRSR) instruction allo ws the user to change the values of t he

Block Protect (BP1, BP0) bits, to define the si ze of the area that is to be tr eated as read-

only, 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 (SR WD) 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):

●If Write Protect (W) is drive n High, it is possib le t o write to the Status Register p rov ided

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 Lat ch (WEL) bi t has previously been set b y a Write Enab le (WREN)

instruction. (Attempts to write to the Status Re gister are r ejected, an d are n ot 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

23/51

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 Softw are Protected mode (SPM), using the Bloc k Protect

(BP1, BP0) bits of the Stat us Register, can be used.

6.6 Read Data Bytes (READ)

The de vice is first selected by driving Chip Select (S) Low. The instruction code f or 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 b yte 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, Prog ra m or Write cycle is in progress, is rejected without having

any effects on the cycle that is in progress.

A0) and a dummy byte, each bit being latched-in during the rising edge of Serial Clock (C).

Then the memo ry contents, at that addre ss, is shift ed out on Serial Data ou tput (Q), each bi t

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

to the next higher address after each b yte of data is shifted out. The whole memory can,

therefore, be read with a single Read Data Bytes at Higher Spee d (FAST_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 at Higher Speed (FAST_READ) instruction is term inated by driving

Chip Select (S) High. Chip Select (S) can be driv en High at an y time during data output. An y

Read Data Bytes at Higher Speed (FAST_READ) instruction, while an Erase, Program or

Write cycle is in progress, is rejected without having any effects on the cycle that is in

6.8 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 ha ve been executed. After the Write Enable (WREN) instruction has been

decoded, the device sets the Write Enable Latc h (WEL).

The Page Program (PP) instruction is entered by driving Chip Select (S) Low, followed by

the instruction code, three address b ytes 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 tha n 256 bytes are sent t o the device, p reviously latched data ar e disca rded and th e

last 256 dat a bytes ar e guaranteed to be progr ammed corr ectly within the same pag e. 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

Progr am (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 b yte 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 Prog ram cycle is in progre ss, th e 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.

6.9 Sector Erase (SE)

The Sector Er ase (SE) instruction se ts to ‘1’ (FFh) a ll bits inside t he chosen se ctor. Before it

can be accepted, a Write Enable (WREN) instruction must previously have been e xecuted.

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) Lo w, 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 Er ase (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 (S E) 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 unspe cified

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

6.10 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 Progre ss (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 Bloc k Protect (BP1 , BP0) bits are 0.

The Bulk Erase (BE) instr uc tio n is igno re d if one, or more, sectors are pro tec te d.

6.11 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 me ch an ism , wh ile the device is not in active use, as in this mode, the device

ignores all write, program and erase inst ructions.

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 Power-

down 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 tak e the de vice out of Deep Pow er-do wn mode , the Release from Deep Power-do wn 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 Pow er -do wn, and Re ad Electro nic Signature (RES) instruction and

the Read Identifica tion (RDID) instruction also allo w the electronic signat ure of the de vice 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 r educe d

to ICC2 and the Deep Power-down mode is entered.

Any Deep Pow er-down (DP) instruction, while an Erase, Pr ogram or Write cycle is in

progress, is rejected without having any effects on the cycle that is in progress.

6.12 Release from Deep Power-down and Read Electronic

Signature (RES)

To tak e the de vice out of Deep Pow er-do wn mode , the Release from Deep Power-do wn 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 el ectronic

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 alw ays 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 fr om Deep Power-down and Read Electronic Signature (R ES) instruction while

an Erase , Progr am 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 sig nature, 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 repe atedly.

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, th e transition to the Standby

Power mode is immediate. If the device was previously in the Deep Power-down mod e,

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 b yte has be en receiv ed b y the device,

but before the whole of the 8-bit el ectronic 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, th e transition to the Standby

Power mode is immediate. If the device was previously in the Deep Power-down mod e,

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.

7 Power-up and power-down

At power-up and powe r-down, the de vice must not be selected (that is Chip Select ( S) m ust

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 opera tion of t he device is not guaranteed if, by this t ime , V CC is still belo w 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 de vice in a system should ha v e the V CC rail decoupled b y a suitab le capacitor close to

the package pins. (Gener ally, this capacitor is of the order of 0.1 µF).

At power-down, when VCC drops from th e 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 prog ress, some data corruption can result).
