Description M25P80

6/52

1 Description

The M25P80 is an 8 Mbit (1 Mbit × 8) Serial Flash memory, with advanced write protection

mechanisms, accessed by a high speed SPI-co mpa tible bus.

The memory can be programmed 1 to 256 bytes at a time, using the Page Program

instruction.

The memory is organized as 16 sec to rs, each contain i n g 25 6 pa g es. Each page is 256

bytes wide. Thus, the whole memory can be viewed as consisting of 4096 pages, or

1,048,576 bytes.

The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,

using the Sector Erase instruction.

In order to meet environmental requirements, ST offers the M25P80 in ECOPACK®

packages. ECOPACK® packages are Lead-free and RoHS compliant.

ECOPACK is an ST tr ademark. ECOPACK specificat ions are available at: www.st.com.

2 Signal description

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. Value s 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 de vice 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 Po wer-down mode). Driving

Chip Select (S) Low enables the device, placing it in the active power mode.

After Power-up, a falling edge on Chip Select (S) is requir ed 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 impe da nc e, 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 signa l is to free ze the size of the area of memory that is

protected against pro g ram or er ase instructions (as specified by the values in t he BP2, BP1

and BP0 bits of the Status Re gister).

2.7 VCC supply voltage

VCC is the supply voltage.

2.8 VSS ground

VSS is the reference for the VCC supply voltage.

SPI modes M25P80

10/52

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 t he t w o mod es, as 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 Master an d memory devi ces 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 M25P80 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 e xample, 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, assuming that the tim e co nst an t 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 impe dance.

Operating features M25P80

4 Operating features

4.1 Page Programming

To prog ram one data b yte, two in structions 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 t PP).

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), pro vided 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 15: AC characteristics (75 MHz operation, 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 er ased 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 Cycle

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

(SE or BE) can be achieved b y no t 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 enabled, and in the Active Power mode.

When Chip Select (S) is High, the device is disabled, 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 Enter Deep

Power-down mode (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 mode an d Read Electronic Signature (RES) instruction) is executed.

All other instructions are ignored while the d evice is in the Deep Power-down mode. 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.

4.5 Status Register

The Status Regist er conta ins a n umber o f stat us and cont rol bit s that can be rea d or set (a s

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

M25P80 boasts 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.

●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 Enable Latch (WEL) bit. This bit is re turned to its re set state

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 (BP2, BP1, BP0) bits allow part of the memory to be config ur ed as

read-only. This is the Software Protected Mode (SPM).

●The Write Protect (W) signal allows the Block Protect (BP2, BP1, BP0) bits and Status

Mode (HPM).

●In addition to the low power consumption feature, the Deep Power-down mode offers

e xtra softw are protection from inadv ertent Write , Program and Erase instructions, as all

instructions are ignored except one particular instruction (the Release from Deep

Power-down instruction).

4.7 Hold condition

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

resetting the clocking seque nce. However, taking this signal Low does not terminate any

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

To enter the Hold condition, the device must be selected, with Chip Se lect (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 impe da nc e, and Serial Data

Input (D) and Serial Clock (C) are Don’t Care.

Normally, the device is kept selected, with Chip Select (S) driv en Lo w, f or the whole dur ation

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 significan t bit

first.

Serial Data Input (D) is sampled on the first rising edge of Serial Cloc k (C) after Chip Select

(S) is drive n L ow. Then, t he on e- byte i nstruction code must be shifte d 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 st arts 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.

In the case of a Read Data Bytes (READ), Read Data Bytes at Higher Speed (Fast_Read),

Read Status Register (RDSR), Read Identification (RDID) 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), Write 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 ex act 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.

6.1 Write Enable (WREN)

The Write Enable (WREN) instruction (Figure 7) sets the Write Enable Latch (WEL) bit.

The Write Enable Latch (WEL) bit must be set prior to every Page Program (PP), Sector

Erase (SE), Bulk Erase (BE) and Write Status Register (WRSR) instruction.

The Write Enable (WREN) instruction is entere d b y driving Chip Select (S) Lo w, sending the

instruction code, an d then driving Chip Select (S) High.

6.3 Read Identification (RDID)

The Read Identification (RDID) instruction allows to read the device identification data:

●Manufacturer identification (one byte)

●De vice identification (two bytes)

●A Unique ID code (UID) followed by 16 bytes of CFI data

The manufacturer identification is assigned by JEDEC, and has the value 20h for

STMicroelectronics. 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 de vice in

the second byte (14h). The UID is set to 10h and indicate s that 16 bytes, related to the CFI

content, are following.

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 device is first selected by driving Chip Select (S) Low. Then, the 8-bit instruction code

for the instruction is shifted in. After this, the 24-bit device identification, stored in the

memory, the 8-bit Unique ID code followed by 16 bytes of CFI content will be shifted out on

Serial Data Output (Q). Each bit is 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 Pow er mode, the de vice w aits to be selected, 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, even while a Program, Er ase 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 inte rnal Write Enable Latch is set, when set to 0 t he internal Write Enable

Latch is reset and no Write Status Register, Program or Erase instruction is accepted.

6.4.3 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 instructions. These bits ar e written with

the Write Status Register (WRSR) instruction. When one or both of the Block Protect (BP2,

BP1, BP0) bits is set to 1, the relevant memory area (as defined in Table 2) becomes

protected against P age Program (PP) and Sector Erase (SE) instructions. The Block Protect

(BP2, BP1, BP0) bits can be written provided that the Hardware Protected mode has not

been set. The Bulk Er ase (BE) instruction is executed if , and only if, both Block Protect

(BP2, BP1, BP0) bits are 0.

6.4.4 SRWD bit

The Status Register Write Disable (SRWD) bit is operated in conjunction with th e 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 Prot ect ( W ) is driv en Lo w). In this mode, the

non-volatile bits of the Status Register (SRWD, BP2, BP1, BP0) be come read-only bits an d

the Write Status Register (WRSR) instruction is no longer accepted for e xecution.

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 an d

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, b1 and b0 of the

Status Register. b6 and b5 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.

When the cycle is completed, the Write Enab le Latch (WEL) is reset.

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

Block Protect (BP2, BP1, BP0) bits, to define the size of the area that is to be treated as

read-only, as defined in Table 2. The Write Status Register (WRSR) ins truction also allows

the user to set or reset th e Status Register Write Disable (SR WD) 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 provid ed 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 driven High, it is possible to write to the St atus 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 by a Write Enab le (WREN)

instruction. (Attempts to write to the Status Register are reject ed, and ar e not accepte d

for execution). As a consequence, all the data bytes in the memory area t hat are

software protected (SPM) by the Block Protect (BP2, BP1, BP0) bits of the Status

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

(BP2, BP1, BP0) bits of the Status Register, can be used.

6.6 Read Data Bytes (READ)

The de vice is first selected by driving Chip Select (S) Low. Th e 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 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 b y 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.

6.7 Read Data Bytes at Higher Speed (FAST_READ)

The de vice is first selected by driving Chip Select (S) Low. Th e instruction code f or the Read

Data Bytes at Higher Speed (FAST_READ) instruction is f ollo w ed by a 3-byte address (A23-

A0) 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 shift ed 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

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 Byte s at Higher Speed (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 terminated 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

progress.

6.8 Page Program (PP)

The Page Program (PP) instruction allows b ytes to be programmed in the mem ory

(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 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 entir e duration of the sequence .

The instruction sequence is shown in Figure 14.

If more tha n 256 bytes are se nt t o the device, previously latched data are discard ed an d the

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 15: A C

characteristics (75 MHz operation, 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 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

(BP2, BP1, BP0) bits (see Table 3 and Table 2) is not executed.

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) Lo w, followed by the

instruction code, an d three address bytes on Serial Data In put (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 (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

(BP2, BP1, BP0) bits (see Table 3 and Table 2) is not executed.

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 dur ation 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 Era se (BE) instruction is e x ecuted only if all Bloc k Protect (BP2, BP1, BP0) bits are

0. The Bulk Erase (BE) instruction is ignored if one, o r more, sectors are protected.

6.11 Deep Power- down (DP)

Executing the Deep Po wer-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 an extra

softwar e protecti on mechanism, wh ile the device is not in activ e use , since in this m ode , the

device ignores all Write, Program and Erase instructions.

Driving Chip Select (S) High deselects the device, and puts the device in the Standby mo de

(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).

Once the device has entered the Deep Power-down mode, all instructions are ignored

except the Release from Deep Power-down and Read Electronic Signature (RES)

instruction. This releases the device from this mode. The Release from Deep Power-down

and Read Electronic Signatur e (RES) in struction also allows the Electronic Signature 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 bef ore t he supply curr ent is redu ced

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.

6.12 Release from Deep Power-down and Read Electronic

Signature (RES)

Once the device has entered the Deep Power-down mode, all instructions are ignored

except the Release from Deep Power-down and Read Electronic Signature (RES)

instruction. Executing this instruction takes the device out of the 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 M25P80 is 13h.

Please note that this is not the same as, or even a subset of, the JEDEC 16-bit Electronic

Signature that is read by the Read Identifier (RDID) inst ruction. The ol d-style Electronic

Signature is supported for reasons of backward compatibility, only, and should not be used

for new designs. New designs should, instead, mak e use of the JEDEC 16-bit Electronic

Signature, and the Read Iden tifier (RDID) instruction.

Except while an Erase, Program or Write Status Register cycle is in progress, the Release

from Deep Power-do wn 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 Relea se from Deep P o wer-do wn and Read Ele ctronic 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). The n, the 8-bit Electronic Sig natu re , sto red in t he 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 Stan dby

Power mode is immediate. If the device was previously in the Deep Pow er-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 15. 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 Electronic Signature has been transmitted for the first time

(as shown in Figure 19), still insures 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 Stan dby

Power mode is immediate. If the device was previously in the Deep Pow er-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 15. 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 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 Powe r-down

A safe configuration is provided in Section 3: SPI modes.

To avoid data corruption and inadvertent write operations during Powe r-up, a Power On

Reset (POR) circuit is included. The logic inside the device is held reset while VCC is less

than the POR thre shold value , VWI – all operations are disabled, and the device does not

respond to any instruction.

Moreover, the de vice 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 time, 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 tak en f or supply rail decoupling, to stabilize the VCC f eed. Each

device in a system should ha ve the VCC rail decoupled by a suitable capacitor close to the

package pins. (Generally, this capacitor is of the order of 100 nF).

At Power-down, when VCC drops from the operating voltage, to below the Power On Reset

(POR) threshold va lue, VWI, all operations are disabled and the device does not respond to

any inst ruction. (The designer nee ds to be a w are th at if a Pow er-do wn occu rs while a Write,

Program or Erase cycle is in progress, some data corruption can result.)
