Signal Descriptions

Table 2: Signal Descriptions

Signal Type Description

DQ1 Output Serial data: The DQ1 output signal is used to transfer data serially out of the device.

Data is shifted out on the falling edge of the serial clock (C).

DQ0 Input Serial data: The DQ0 input signal is used to transfer data serially into the device. It

receives commands, addresses, and the data to be programmed. Values are latched on

the rising edge of the serial clock (C).

C Input Clock: The C input signal provides the timing of the serial interface. Commands, ad-

dresses, or data present at serial data input (DQ0) is latched on the rising edge of the

serial clock (C). Data on DQ1 changes after the falling edge of C.

S# Input Chip select: When the S# input signal is HIGH, the device is deselected and DQ1 is at

high impedance. Unless an internal PROGRAM, ERASE, or WRITE STATUS REGISTER cy-

cle is in progress, the device will be in the standby power mode (not the deep power-

down mode). Driving S# LOW enables the device, placing it in the active power mode.

After power-up, a falling edge on S# is required prior to the start of any command.

HOLD# Input Hold: The HOLD# signal is used to pause any serial communications with the device

without deselecting the device. During the hold condition, DQ1 is High-Z. DQ0 and C

are "Don’t Care." To start the hold condition, the device must be selected, with S#

driven LOW.

W#/VPP Input Write protect: The W#/VPP signal is both a control input and a power supply pin. The

two functions are selected by the voltage range applied to the pin. If the W#/VPP input

is kept in a low voltage range (0 V to VCC) the pin is seen as a control input. The W#

input signal is used to freeze the size of the area of memory that is protected against

program or erase commands as specified by the values in BP2, BP1, and BP0 bits of the

Status Register. VPP acts as an additional power supply if it is in the range of VPPH, as

defined in the AC Measurement Conditions table. Avoid applying VPPH to the W#/VPP

pin during a BULK ERASE operation.

SPI Modes

These devices can be driven by a microcontroller with its serial peripheral interface

(SPI) running in either of the following two SPI 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 C.

The difference between the two modes is the clock polarity when the bus master is in

standby mode and not transferring data:

• C remains at 0 for (CPOL = 0, CPHA = 0)

• C remains at 1 for (CPOL = 1, CPHA = 1)

Because only one device is selected at a time, only one device drives the serial data out-

put (DQ1) line at a time, while the other devices are High-Z. An example of three devi-

ces connected to an MCU on an SPI bus is shown here.

Notes: 1. WRITE PROTECT (W#) and HOLD# should be driven HIGH or LOW as appropriate.

2. Resistors (R) ensure that the memory device is not selected if the bus master leaves the

S# line High-Z.

3. The bus master may enter a state where all I/O are High-Z at the same time; for exam-

ple, when the bus master is reset. Therefore, C must be connected to an external pull-

down resistor so that when all I/O are High-Z, S# is pulled HIGH while C is pulled LOW.

This ensures that S# and C do not go HIGH at the same time and that the tSHCH require-

ment is met.

4. The typical value of R is 100kΩ, 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 High-Z.

5. Example: Given that Cp = 50pF (R × Cp = 5μs), the application must ensure that the bus

master never leaves the SPI bus High-Z for a time period shorter than 5μs.

Operating Features

Page Programming

To program one data byte, two commands are required: WRITE ENABLE, which is one

byte, and a PAGE PROGRAM sequence, which is four bytes plus data. This is followed by

the internal PROGRAM cycle of duration tPP. To spread this overhead, the PAGE PRO-

GRAM command allows up to 256 bytes to be programmed at a time (changing bits

from 1 to 0), provided they lie in consecutive addresses on the same page of memory. To

optimize timings, it is recommended to use the PAGE PROGRAM command to program

all consecutive targeted bytes in a single sequence than to use several PAGE PROGRAM

sequences with each containing only a few bytes.

Sector Erase, Bulk Erase

The PAGE PROGRAM command 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 ach-

ieved a sector at a time using the SECTOR ERASE command, or throughout the entire

memory using the BULK ERASE command. This starts an internal ERASE cycle of dura-

tion tSE or tBE. The ERASE command must be preceded by a WRITE ENABLE command.

Polling during a Write, Program, or Erase Cycle

An improvement in the time to complete the following commands can be achieved by

not waiting for the worst case delay (tW, tPP, tSE, or tBE).

• WRITE STATUS REGISTER

• PROGRAM

• ERASE (SECTOR ERASE, BULK ERASE)

The write in progress (WIP) bit is provided in the status register so that the application

program can monitor this bit in the status register, polling it to establish when the pre-

vious WRITE cycle, PROGRAM cycle, or ERASE cycle is complete.

Active Power, Standby Power, and Deep Power-Down

When chip select (S#) is LOW, the device is selected, and in the ACTIVE POWER mode.

When 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

sumption drops to ICC1.

The DEEP POWER-DOWN mode is entered when the DEEP POWER-DOWN command

is executed. The device consumption drops further to ICC2. The device remains in this

mode until the RELEASE FROM DEEP POWER-DOWN command is executed. While in

the DEEP POWER-DOWN mode, the device ignores all WRITE, PROGRAM, and ERASE

commands. This provides an extra software protection mechanism when the device is

not in active use, by protecting the device from inadvertent WRITE, PROGRAM, or

ERASE operations. For further information, see the DEEP POWER DOWN command.

m25p10A.pdf - Rev. C 05/18 EN 11 Micron Technology, Inc. reserves the right to change products or specifications without notice.

Status Register

The status register contains a number of status and control bits that can be read or set

(as appropriate) by specific commands. For a detailed description of the status register

bits, see READ STATUS REGISTER (page 24).

Data Protection by Protocol

Non-volatile memory is used in environments that can include excessive noise. The fol-

lowing capabilities help protect data in these noisy environments.

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 commands are checked before they

are accepted for execution to ensure they consist of a number of clock pulses that is a

multiple of eight.

All commands that modify data must be preceded by a WRITE ENABLE command to set

the write enable latch (WEL) bit.

In addition to the low power consumption feature, the DEEP POWER-DOWN mode of-

fers extra software protection since all PROGRAM, and ERASE commands are ignored

when the device is in this mode.

Software Data Protection

Memory can be configured as read-only using the block protect bits (BP2, BP1, BP0) as

shown in the Protected Area Sizes table.

Hardware Data Protection

Hardware data protection is implemented using the write protect signal applied on the

W# pin. This freezes the status register in a read-only mode. In this mode, the block pro-

tect (BP) bits and the status register write disable bit (SRWD) are protected.

Hold Condition

The 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 S# LOW. The hold condi-

tion starts on the falling edge of the HOLD# signal, if this coincides with serial clock (C)

being LOW. The hold condition ends on the rising edge of the HOLD# signal, if this co-

incides with C being LOW. If the falling edge does not coincide with C being LOW, the

hold condition starts after C next goes LOW. Similarly, if the rising edge does not coin-

cide with C being LOW, the hold condition ends after C next goes LOW.

During the hold condition, DQ1 is HIGH impedance while DQ0 and C are Don’t Care.

Typically, the device remains selected with S# driven LOW for the duration of the hold

condition. This ensures that the state of the internal logic remains unchanged from the

moment of entering the hold condition. If S# goes HIGH while the device is in the hold

condition, the internal logic of the device is reset. To restart communication with the

device, it is necessary to drive HOLD# HIGH, and then to drive S# LOW. This prevents

the device from going back to the hold condition.

Command Set Overview

All commands, addresses, and data are shifted in and out of the device, most significant

bit first.

Serial data input DQ0 is sampled on the first rising edge of serial clock (C) after chip se-

lect (S#) is driven LOW. Then, the one-byte command code must be shifted in to the de-

vice, most significant bit first, on DQ1, each bit being latched on the rising edges of C.

Every command sequence starts with a one-byte command code. Depending on the

command, this command code might be followed by address or data bytes, by address

and data bytes, or by neither address or data bytes. For the following commands, the

shifted-in command sequence is followed by a data-out sequence. S# can be driven

HIGH after any bit of the data-out sequence is being shifted out.

• READ DATA BYTES (READ)

• READ DATA BYTES at HIGHER SPEED

• READ STATUS REGISTER

• READ IDENTIFICATION

• RELEASE from DEEP POWER-DOWN

For the following commands, S# must be driven HIGH exactly at a byte boundary. That

is, after an exact multiple of eight clock pulses following S# being driven LOW, S# must

be driven HIGH. Otherwise, the command is rejected and not executed.

• PAGE PROGRAM

• SECTOR ERASE

• BULK ERASE

• WRITE STATUS REGISTER

• WRITE ENABLE

• WRITE DISABLE

• DEEP POWER-DOWN

All attempts to access the memory array are ignored during a WRITE STATUS REGISTER

command cycle, a PROGRAM command cycle, or an ERASE command cycle. In addi-

tion, the internal cycle for each of these commands continues unaffected.

READ IDENTIFICATION

The READ IDENTIFICATION command reads the following device identification data:

• Manufacturer identification (1 byte): This is assigned by JEDEC.

• Device identification (2 bytes): This is assigned by device manufacturer; the first byte

indicates memory type and the second byte indicates device memory capacity.

• A Unique ID code (UID) (17 bytes,16 available upon customer request): The first byte

contains length of data to follow; the remaining 16 bytes contain optional Customized

Factory Data (CFD) content.

Note: 1. The CFD bytes are read-only and can be programmed with customer data upon demand.

If customers do not make requests, the devices are shipped with all the CFD bytes pro-

grammed to zero.

A READ IDENTIFICATION command is not decoded while an ERASE or PROGRAM cy-

cle is in progress and has no effect on a cycle in progress. The READ IDENTIFICATION

command must not be issued while the device is in DEEP POWER-DOWN mode.

The device is first selected by driving S# LOW. Then the 8-bit command code is shifted

in and content is shifted out on DQ1 as follows: the 24-bit device identification that is

stored in the memory, the 8-bit CFD length, followed by 16 bytes of CFD content. Each

bit is shifted out during the falling edge of serial clock (C).

The READ IDENTIFICATION command is terminated by driving S# HIGH at any time

during data output. When S# is driven HIGH, the device is put in the STANDBY POWER

mode and waits to be selected so that it can receive, decode, and execute commands.

WIP Bit

The write in progress (WIP) bit indicates whether the memory is busy with a WRITE

STATUS REGISTER cycle, a PROGRAM cycle, or an ERASE cycle. When the WIP bit is set

to 1, a cycle is in progress; when the WIP bit is set to 0, a cycle is not in progress.

WEL Bit

The write enable latch (WEL) bit indicates the status of the internal write enable latch.

When the WEL bit is set to 1, the internal write enable latch is set; when the WEL bit is

set to 0, the internal write enable latch is reset and no WRITE STATUS REGISTER, PRO-

GRAM, or ERASE command is accepted.

Block Protect Bits

The block protect bits are non-volatile. They define the size of the area to be software

protected against PROGRAM and ERASE commands. The block protect bits are written

with the WRITE STATUS REGISTER command.

When one or more of the block protect bits is set to 1, the relevant memory area, as de-

fined in the Protected Area Sizes table, becomes protected against PAGE PROGRAM and

SECTOR ERASE commands. The block protect bits can be written provided that the

hardware protected mode has not been set. The BULK ERASE command is executed on-

ly if all block protect bits are 0.

SRWD Bit

The status register write disable (SRWD) bit is operated in conjunction with the write

protect (W#/VPP) signal. When the SRWD bit is set to 1 and W#/VPP is driven LOW, the

device is put in the hardware protected mode. In the hardware protected mode, the

non-volatile bits of the status register (SRWD, and the block protect bits) become read-

only bits and the WRITE STATUS REGISTER command is no longer accepted for execu-

tion.

WRITE STATUS REGISTER

The WRITE STATUS REGISTER command allows new values to be written to the status

ABLE command must have been executed previously. After the WRITE ENABLE com-

mand has been decoded and executed, the device sets the write enable latch (WEL) bit.

The WRITE STATUS REGISTER command is entered by driving chip select (S#) LOW,

followed by the command code and the data byte on serial data input (DQ0). The

WRITE STATUS REGISTER command has no effect on b6, b5, b4, b1, and b0 of the sta-

tus register. The status register b6, b5, and b4 are always read as "0". S# must be driven

HIGH after the eighth bit of the data byte has been latched in. If not, the WRITE STATUS

As soon as S# is driven HIGH, the self-timed WRITE STATUS REGISTER cycle is initi-

ated; its duration is tW. While the WRITE STATUS REGISTER cycle is in progress, the sta-

tus register may still be read to check the value of the write in progress (WIP) bit. The

WIP bit is 1 during the self-timed WRITE STATUS REGISTER cycle, and is 0 when the

cycle is completed. Also, when the cycle is completed, the WEL bit is reset.

The WRITE STATUS REGISTER command allows the user to change the values of the

block protect bits (BP2, BP1, BP0). Setting these bit values defines the size of the area

that is to be treated as read-only, as defined in the Protected Area Sizes table.

The WRITE STATUS REGISTER command also allows the user to set and reset the status

The SRWD bit and the W#/VPP signal allow the device to be put in the hardware protec-

ted (HPM) mode. The WRITE STATUS REGISTER command is not executed once the

HPM is entered. The options for enabling the status register protection modes are sum-

marized here.

Notes: 1. Software protection: status register is writable (SRWD, BP2, BP1, and BP0 bit values can

2. PAGE PROGRAM, SECTOR ERASE, and BULK ERASE commands are not accepted.

3. PAGE PROGRAM and SECTOR ERASE commands can be accepted.

4. Hardware protection: status register is not writable (SRWD, BP2, BP1, and BP0 bit values

cannot be changed).

5. PAGE PROGRAM, SECTOR ERASE, and BULK ERASE commands are not accepted.

When the SRWD bit of the status register is 0 (its initial delivery state), it is possible to

write to the status register provided that the WEL bit has been set previously by a WRITE

ENABLE command, regardless of whether the W#/VPP signal is driven HIGH or LOW.

When the status register SRWD bit is set to 1, two cases need to be considered depend-

ing on the state of the W#/VPP signal:

• If the W#/VPP signal is driven HIGH, it is possible to write to the status register provi-

ded that the WEL bit has been set previously by a WRITE ENABLE command.

• If the W#/VPP signal is driven LOW, it is not possible to write to the status register even

if the WEL bit has been set previously by a WRITE ENABLE command. Therefore, at-

tempts to write to the status register are rejected, and are not accepted for execution.

The result is that all the data bytes in the memory area that have been put in SPM by

the status register block protect bits (BP2, BP1, BP0) are also hardware protected

against data modification.

Regardless of the order of the two events, the HPM can be entered in either of the fol-

lowing ways:

• Setting the status register SRWD bit after driving the W#/VPP signal LOW

• Driving the W#/VPP signal LOW after setting the status register SRWD bit.

The only way to exit the HPM is to pull the W#/VPP signal HIGH. If the W#/VPP signal is

permanently tied HIGH, the HPM can never be activated. In this case, only the SPM is

available, using the status register block protect bits (BP2, BP1, BP0).

READ DATA BYTES

The device is first selected by driving chip select (S#) LOW. The command code for

READ DATA BYTES 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 (DQ1), each bit being shifted out at a maximum fre-

quency fR during the falling edge of C.

The first byte addressed can be at any location. The address is automatically incremen-

ted to the next higher address after each byte of data is shifted out. Therefore, the entire

memory can be read with a single READ DATA BYTES command. When the highest ad-

dress is reached, the address counter rolls over to 000000h, allowing the read sequence

to be continued indefinitely.

The READ DATA BYTES command is terminated by driving S# HIGH. S# can be driven

HIGH at any time during data output. Any READ DATA BYTES command issued while

an ERASE, PROGRAM, or WRITE cycle is in progress is rejected without any effect on

the cycle that is in progress.

READ DATA BYTES at HIGHER SPEED

The device is first selected by driving chip select (S#) LOW. The command code for the

READ DATA BYTES at HIGHER SPEED command is followed 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 are shifted out on serial data output

(DQ1) at a maximum frequency fC, during the falling edge of C.

The first byte addressed can be at any location. The address is automatically incremen-

ted to the next higher address after each byte of data is shifted out. Therefore, the entire

memory can be read with a single READ DATA BYTES at HIGHER SPEED command.

When the highest address is reached, the address counter rolls over to 000000h, allow-

ing the read sequence to be continued indefinitely.

The READ DATA BYTES at HIGHER SPEED command is terminated by driving S# HIGH.

S# can be driven HIGH at any time during data output. Any READ DATA BYTES at

HIGHER SPEED command issued while an ERASE, PROGRAM, or WRITE cycle is in

progress is rejected without any effect on the cycle that is in progress.

PAGE PROGRAM

The PAGE PROGRAM command allows bytes in the memory to be programmed, which

means the bits are changed from 1 to 0. Before a PAGE PROGRAM command can be ac-

cepted a WRITE ENABLE command must be executed. After the WRITE ENABLE com-

mand has been decoded, the device sets the write enable latch (WEL) bit.

The PAGE PROGRAM command is entered by driving chip select (S#) LOW, followed by

the command code, three address bytes, and at least one data byte on serial data input

(DQ0).

If the eight 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; that is, from the address whose eight least significant bits (A7-A0) are all

zero. S# must be driven LOW for the entire duration of the sequence.

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 any effects on the other bytes of the same page.

For optimized timings, it is recommended to use the PAGE PROGRAM command to

program all consecutive targeted bytes in a single sequence rather than to use several

PAGE PROGRAM sequences, each containing only a few bytes.

S# must be driven HIGH after the eighth bit of the last data byte has been latched in.

Otherwise the PAGE PROGRAM command is not executed.

As soon as S# is driven HIGH, the self-timed PAGE PROGRAM cycle is initiated; the cy-

cles's duration is tPP. 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 WIP bit is 1 during

the self-timed PAGE PROGRAM cycle, and 0 when the cycle is completed. At some un-

specified time before the cycle is completed, the write enable latch (WEL) bit is reset.

A PAGE PROGRAM command is not executed if it applies to a page protected by the

block protect bits BP2, BP1, and BP0.

SECTOR ERASE

The SECTOR ERASE command sets to 1 (FFh) all bits inside the chosen sector. Before

the SECTOR ERASE command can be accepted, a WRITE ENABLE command must have

been executed previously. After the WRITE ENABLE command has been decoded, the

device sets the write enable latch (WEL) bit.

The SECTOR ERASE command is entered by driving chip select (S#) LOW, followed by

the command code, and three address bytes on serial data input (DQ0). Any address in-

side the sector is a valid address for the SECTOR ERASE command. S# must be driven

LOW for the entire duration of the sequence.

S# must be driven HIGH after the eighth bit of the last address byte has been latched in.

Otherwise the SECTOR ERASE command is not executed. As soon as S# is driven HIGH,

the self-timed SECTOR ERASE cycle is initiated; the cycle's duration is tSE. 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 WIP bit is 1 during the self-timed SECTOR ERASE

cycle, and is 0 when the cycle is completed. At some unspecified time before the cycle is

completed, the WEL bit is reset.

A SECTOR ERASE command is not executed if it applies to a sector that is hardware or

software protected.

BULK ERASE

The BULK ERASE command sets all bits to 1 (FFh). Before the BULK ERASE command

can be accepted, a WRITE ENABLE command must have been executed previously. Af-

ter the WRITE ENABLE command has been decoded, the device sets the write enable

latch (WEL) bit.

The BULK ERASE command is entered by driving chip select (S#) LOW, followed by the

command code on serial data input (DQ0). S# must be driven LOW for the entire dura-

tion of the sequence.

S# must be driven HIGH after the eighth bit of the command code has been latched in.

Otherwise the BULK ERASE command is not executed. As soon as S# is driven HIGH,

the self-timed BULK ERASE cycle is initiated; the cycle's duration is tBE. 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 WIP bit is 1 during the self-timed BULK ERASE cycle, and is 0

when the cycle is completed. At some unspecified time before the cycle is completed,

the WEL bit is reset.

The BULK ERASE command is executed only if all block protect (BP2, BP1, BP0) bits are

0. The BULK ERASE command is ignored if one or more sectors are protected.

DEEP POWER-DOWN

Executing the DEEP POWER-DOWN command is the only way to put the device in the

lowest power consumption mode, the DEEP POWER-DOWN mode. The DEEP POWER-

DOWN command can also be used as a software protection mechanism while the de-

vice is not in active use because in the DEEP POWER-DOWN mode the device ignores

all WRITE, PROGRAM, and ERASE commands.

Driving chip select (S#) HIGH deselects the device, and puts it in the STANDBY POWER

mode if there is no internal cycle currently in progress. Once in STANDBY POWER

mode, the DEEP POWER-DOWN mode can be entered by executing the DEEP POWER-

DOWN command, subsequently reducing the standby current from ICC1 to ICC2.

To take the device out of DEEP POWER-DOWN mode, the RELEASE from DEEP POW-

ER-DOWN command must be issued. Other commands must not be issued while the

device is in DEEP POWER-DOWN mode. The DEEP POWER-DOWN mode stops auto-

matically at power-down. The device always powers up in STANDBY POWER mode.

The DEEP POWER-DOWN command is entered by driving S# LOW, followed by the

command code on serial data input (DQ0). S# must be driven LOW for the entire dura-

tion of the sequence.

S# must be driven HIGH after the eighth bit of the command code has been latched in.

Otherwise the DEEP POWER-DOWN command is not executed. As soon as 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 command issued while an ERASE, PROGRAM, or WRITE cy-

cle is in progress is rejected without any effect on the cycle that is in progress.

RELEASE from DEEP POWER-DOWN

Once the device has entered DEEP POWER-DOWN mode, all commands are ignored ex-

cept RELEASE from DEEP POWER-DOWN and READ ELECTRONIC SIGNATURE. Exe-

cuting either of these commands takes the device out of the DEEP POWER-DOWN

mode.

The RELEASE from DEEP POWER-DOWN command is entered by driving chip select

(S#) LOW, followed by the command code on serial data input (DQ0). S# must be driven

LOW for the entire duration of the sequence.

The RELEASE from DEEP POWER-DOWN command is terminated by driving S# HIGH.

Sending additional clock cycles on serial clock C while S# is driven LOW causes the

command to be rejected and not executed.

After S# has been driven HIGH, followed by a delay, tRES, the device is put in the STAND-

BY mode. S# must remain HIGH at least until this period is over. The device waits to be

selected so that it can receive, decode, and execute commands.

Any RELEASE from DEEP POWER-DOWN command issued while an ERASE, PRO-

GRAM, or WRITE cycle is in progress is rejected without any effect on the cycle that is in

progress.

READ ELECTRONIC SIGNATURE

Once the device enters DEEP POWER-DOWN mode, all commands are ignored except

READ ELECTRONIC SIGNATURE and RELEASE from DEEP POWER-DOWN. Executing

either of these commands takes the device out of the DEEP POWER-DOWN mode.

The READ ELECTRONIC SIGNATURE command is entered by driving chip select (S#)

LOW, followed by the command code and three dummy bytes on serial data input

(DQ0) . Each bit is latched in on the rising edge of serial clock C. The 8-bit electronic

signature is shifted out on serial data output DQ1 on the falling edge of C; S# must be

driven LOW the entire duration of the sequence for the electronic signature to be read.

However, driving S# HIGH after the command code, but before the entire 8-bit electron-

ic signature has been output for the first time, still ensures that the device is put into

STANDBY mode.

Except while an ERASE, PROGRAM, or WRITE STATUS REGISTER cycle is in progress,

the READ ELECTRONIC SIGNATURE command provides access to the 8-bit electronic

signature of the device, and can be applied even if DEEP POWER-DOWN mode has not

been entered. The READ ELECTRONIC SIGNATURE command is not executed while an

ERASE, PROGRAM, or WRITE STATUS REGISTER cycle is in progress and has no effect

on the cycle in progress.

The READ ELECTRONIC SIGNATURE command is terminated by driving S# high after

the electronic signature has been read at least once. Sending additional clock cycles C

while S# is driven LOW causes the electronic signature to be output repeatedly.

If S# is driven HIGH, the device is put in STANDBY mode immediately unless it was pre-

viously in DEEP POWER-DOWN mode. If previously in DEEP POWER-DOWN mode, the

device transitions to STANDBY mode with delay as described here. Once in STANDBY

mode, the device waits to be selected so that it can receive, decode, and execute instruc-

tions.

• If S# is driven HIGH before the electronic signature is read, transition to STANDBY

mode is delayed by tRES1, as shown in the RELEASE from DEEP POWER-DOWN com-

mand sequence. S# must remain HIGH for at least tRES1(max).

• If S# is driven HIGH after the electronic signature is read, transition to STANDBY

mode is delayed by tRES2. S# must remain HIGH for at least tRES2(max).

Power-Up/Down and Supply Line Decoupling

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 the SPI Modes section.

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 POR threshold voltage, VWI – all operations are disabled, and the device

does not respond to any instruction. Moreover, the device ignores the following instruc-

tions until a time delay of tPUW has elapsed after the moment that VCC rises above the

VWI threshold:

• WRITE ENABLE

• PAGE PROGRAM

• SECTOR ERASE

• BULK ERASE

• WRITE STATUS REGISTER

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 instruction should

be sent until:

•tPUW after VCC has passed the VWI threshold

•tVSL after VCC has passed the VCC,min level

If the time, tVSL, has elapsed, after VCC rises above VCC,min, the device can be selected

for READ instructions even if the tPUW delay has not yet fully elapsed.

VPPH must be applied only when VCC is stable and in the VCC,min to VCC,max voltage

range.

After power-up, the device is in the following state:

• Standby power mode (not the deep power-down mode)

• Write enable latch (WEL) bit is reset

• Write in progress (WIP) bit is reset

• Write lock bit = 0

• Lock down bit = 0

Normal precautions must be taken for supply line decoupling to stabilize the VCC sup-

ply. Each device in a system should have the VCC line 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 POR threshold

voltage VWI, all operations are disabled and the device does not respond to any instruc-

tion.

Note: If power-down occurs while a WRITE, PROGRAM, or ERASE cycle is in progress,

some data corruption may result.
