SIGNAL DESCRIPTION
Serial Data Output (DO). This output signal is used to
transfer data serially out of the device. Data is shifted out on
the falling edge of Serial Clock (C).
The DO pin is also used as an input pin when the Fast Read
Dual Input-Output instruction and Dual Input Fast Program is
executed.
Serial Data Input (DIO). 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).
The DIO pin is also used as an output pin when the Fast
Read Dual Output instruction and the Fast Read Dual
Input-Output instruction are executed.
Serial Clock (C). This input signal provides the timing of the
serial interface. Instructions, addresses, or data present at
Serial Data Input (DIO) are latched on the rising edge of
Serial Clock (C). Data on Serial Data Output (DO) changes
after the falling edge of Serial Clock (C).
Chip Select ( S ). When this input signal is High, the device
is deselected and Serial Data Output (DO) is at high
impedance. Unless an internal Program, Erase or Write
(March, 2012, Version 2.0)
Status Register cycle is in progress, the device will be in the
Standby mode (this is not the Deep Power-down mode).
Driving Chip Select ( S ) Low enables 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.
Hold ( HOLD ). The Hold ( HOLD ) signal is used to pause
any serial communications with the device without
deselecting the device.
During the Hold condition, the Serial Data Output (DO) is
high impedance, and Serial Data Input (DIO) and Serial
Clock (C) are Don’t Care. To start the Hold condition, the
device must be selected, with Chip Select ( S ) driven Low.
Write Protect ( W ). The main purpose of this input signal is
to freeze the size of the area of memory that is protected
against program or erase instructions (as specified by the
values in the BP2, BP1, and BP0 bits of the Status Register).

SPI MODES
falling edge of Serial Clock (C).
The difference between the two modes, as shown in Figure 2,
is the clock polarity when the bus master is in Stand-by mode
and not transferring data:
– C remains at 0 for (CPOL=0, CPHA=0)
– C remains at 1 for (CPOL=1, CPHA=1)
These devices can be driven by a microcontroller with its SPI
peripheral running in either of the two following modes:
– CPOL=0, CPHA=0
– CPOL=1, CPHA=1
For these two modes, input data is latched in on the rising
edge of Serial Clock (C), and output data is available from the

OPERATING FEATURES
WIP bit. The Write In Progress (WIP) bit indicates whether
the memory is busy with a Write Status Register, Program or
Erase cycle.
Page Programming
To program one data byte, two instructions are required: Write
Enable (WREN), which is one byte, and a Page Program (PP)
sequence, which consists of four bytes plus data. This is
followed by the internal Program cycle (of duration tPP).
To spread this overhead, the Page Program (PP) instruction
allows up to 256 bytes to be programmed at a time (changing
bits from 1 to 0), provided that they lie in consecutive
addresses on the same page of memory.
WEL bit. The Write Enable Latch (WEL) bit indicates the
status of the internal Write Enable Latch.
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.
Sector Erase, Block Erase, and Chip Erase
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. In this mode, the non-volatile bits of the
Status Register (SRWD, BP2, BP1, BP0) become read-only
bits.
The Page Program (PP) instruction and Dual Input Fast
Program (DIFP) instruction allow bits to be reset from 1 to 0.
Before this can be applied, the bytes of memory need to have
been erased to all 1s (FFh). This can be achieved, a sector at
a time, using the Sector Erase (SE) instruction, a block at a
time, using the Block Erase (BE) instruction, or throughout the
entire memory, using the Chip Erase (CE) instruction. This
starts an internal Erase cycle (of duration tSE, tBE, or tCE).
The Erase instruction must be preceded by a Write Enable
(WREN) instruction.
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
A25L016 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.
„ Program, Erase and Write Status Register instructions are
checked that they consist of a number of clock pulses that
is a multiple of eight, before they are accepted for
execution.
„ All instructions that modify data must be preceded by a
Write Enable (WREN) instruction to set the Write Enable
Latch (WEL) bit. This bit is returned to its reset state by
the following events:
- Power-up
- Write Disable (WRDI) instruction completion
- Write Status Register (WRSR) instruction completion
- Page Program (PP) instruction completion
- Sector Erase (SE) instruction completion
- Block Erase (BE) instruction completion
- Chip Erase (CE) instruction completion
„ The Block Protect (BP2, BP1, BP0) bits allow part of the
memory to be configured 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 Register Write Disable
(SRWD) bit to be 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
from inadvertent Write, Program and Erase instructions, as
all instructions are ignored except one particular instruction
(the Release from Deep Power-down instruction).
Polling During a Write, Program or Erase Cycle
A further improvement in the time to Write Status Register
(WRSR), Program (PP) or Erase (SE, BE, or CE) can be
achieved by not waiting for the worst case delay (tW, tPP, tSE,
tBE, tCE). The Write In Progress (WIP) bit is provided in the
Status Register so that the application program can monitor
its value, polling it to establish when the previous Write cycle,
Program cycle or Erase cycle is complete.
Active Power, Stand-by 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 Stand-by Power mode. The device
consumption drops to ICC1.
The Deep Power-down mode is entered when the specific
instruction (the 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 and Read
Electronic Signature (RES) instruction) is executed.
All other instructions are ignored while the device 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.
Status Register
The Status Register contains a number of status and control
bits that can be read or set (as appropriate) by specific
instructions.

Hold Condition
Serial Clock (C) next goes Low. This is shown in Figure 3.
During the Hold condition, the Serial Data Output (DO) is high
impedance, and Serial Data Input (DIO) and Serial Clock (C)
are Don’t Care.
Normally, the device is kept selected, with Chip Select ( S )
driven Low, for the whole duration of the Hold condition. This
is to ensure that the state of the internal logic remains
unchanged from the moment of entering the Hold condition.
If Chip Select ( S ) goes High while the device is in the Hold
condition, this has the effect of resetting the internal logic of
the device. To restart communication with the device, it is
necessary to drive Hold ( HOLD ) High, and then to drive
The Hold ( HOLD ) signal is used to pause any serial
communications with the device without resetting the clocking
sequence. However, taking this signal Low does not
terminate any Write Status Register, Program or Erase cycle
that is currently in progress.
To enter the Hold condition, the device must be selected, with
Chip Select ( S ) Low.
The Hold condition starts on the falling edge of the Hold
( HOLD ) signal, provided that this coincides with Serial Clock
(C) being Low (as shown in Figure 3.).
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
Chip Select ( S ) Low. This prevents the device from going
back to the Hold condition.

INSTRUCTIONS
All instructions, addresses and data are shifted in and out of
the device, most significant bit first.
Serial Data Input (DIO) is sampled on the first rising edge of
Serial Clock (C) after Chip Select ( S ) is driven Low. Then, the
one-byte instruction code must be shifted in to the device,
most significant bit first, on Serial Data Input (DIO), each bit
being latched on the rising edges of Serial Clock (C).
The instruction set is listed in Table 3.
Every instruction sequence starts with a one-byte instruction
code. Depending on the instruction, this might be followed by
address bytes, or by data bytes, or by both or none.
In the case of a Read Data Bytes (READ), Read Data Bytes at
Higher Speed (Fast_Read), Read Identification (RDID), Read
Electronic Manufacturer and Device Identification (REMS),
Read Status Register (RDSR) or Release from Deep
Power-down, Read Device Identification and Read Electronic
Signature (RES) instruction, the shifted-in instruction sequence is followed by a data-out sequence. Chip Select ( S )
can be driven High after any bit of the data-out sequence is
being shifted out.
In the case of a Page Program (PP), Sector Erase (SE), Block
Erase (BE), Chip Erase (CE), Write Status Register (WRSR),
Write Enable (WREN), Write Disable (WRDI) or Deep
Power-down (DP) instruction, Chip Select ( S ) must be driven
High exactly at a byte boundary, otherwise the instruction is
rejected, and is not executed. That is, Chip Select ( S ) must
driven High when the number of clock pulses after Chip Select
( S ) being driven Low is an exact multiple of eight.
All attempts to access the memory array during a Write Status
Register cycle, Program cycle or Erase cycle are ignored, and
the internal Write Status Register cycle, Program cycle or
Erase cycle continues unaffected.

Read Status Register (RDSR)
The Read Status Register (RDSR) instruction allows the
Status Register to be read. The Status Register may be read
at any time, even while a Program, Erase or Write Status
Register cycle is in progress. When one of these cycles is in
progress, it is recommended to check the Write In Progress
(WIP) bit before sending a new instruction to the device. It is
also possible to read the Status Register continuously, as
shown in Figure 6.

Write In Progress Bit
The status and control bits of the Status Register are as
follows:
WIP bit. The Write In Progress (WIP) bit indicates whether
the memory is busy with a Write Status Register, Program or
Erase cycle. When set to 1, such a cycle is in progress, when
reset to 0 no such cycle is in progress.
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.
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 are written with the Write Status Register (WRSR)
instruction. When one or more of the Block Protect (BP2,
BP1, BP0) bits is set to 1, the relevant memory area (as
defined in Table 1.) becomes protected against Page
Program (PP), Sector Erase (SE), and Block Erase (BE)
instructions. The Block Protect (BP2, BP1, BP0) bits can be
written provided that the Hardware Protected mode has not
been set. The Chip Erase (CE) instruction is executed if, and
only if, all Block Protect (BP2, BP1, BP0) bits are 0.
SRWD bit. The Status Register Write Disable (SRWD) bit is
operated in conjunction with the Write Protect ( W ) signal.
The Status Register Write Disable (SRWD) bit and Write
Protect ( W ) signal allow the device to be put in the
Hardware Protected mode (when the Status Register Write
Disable (SRWD) bit is set to 1, and Write Protect ( W ) is
driven Low). In this mode, the non-volatile bits of the Status
Register (SRWD, BP2, BP1, BP0) become read-only bits and
the Write Status Register (WRSR) instruction is no longer
accepted for execution.

Write Status Register (WRSR)
The Write Status Register (WRSR) instruction allows new
values to be written to the Status Register. Before it can be
accepted, a Write Enable (WREN) instruction must
previously have been executed. After the Write Enable
(WREN) instruction has been decoded and executed, the
device sets the Write Enable Latch (WEL).

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 Enable Latch (WEL) is reset.
The Write Status Register (WRSR) instruction allows 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 1. 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.

as 0.

Note: 1. As defined by the values in the Block Protect (BP2, BP1, BP0) bits of the Status Register, as shown in Table 1.
The protection features of the device are summarized in Table
5.
When the Status Register Write Disable (SRWD) bit of the
Status Register is 0 (its initial delivery state), it is possible to
write to the Status Register provided that the Write Enable
Latch (WEL) bit has previously been set by a Write Enable
(WREN) instruction, regardless of the whether Write Protect
( W ) is driven High or Low.
When the Status Register Write Disable (SRWD) bit of the
Status Register is set to 1, two cases need to be considered,
depending on the state of Write Protect ( W ):
­ If Write Protect ( W ) is driven High, it is possible to write
to the Status Register provided that the Write Enable
Latch (WEL) bit has previously been set by a Write
Enable (WREN) instruction.
­ If Write Protect (W) is driven Low, it is not possible to
write to the Status Register even if the Write Enable Latch
(WEL) bit has previously been set by a Write Enable
(WREN) instruction. (Attempts to write to the Status
(March, 2012, Version 2.0)
Register are rejected, and are not accepted for execution).
As a consequence, all the data bytes in the memory area
that are software protected (SPM) by the Block Protect
(BP2, BP1, BP0) bits of the Status Register, are also
hardware protected against data modification.
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.

Read Data Bytes (READ)
The device is first selected by driving Chip Select ( S ) Low.
The instruction code for the Read Data Bytes (READ)
instruction is followed by a 3-byte address (A23-A0), each bit
being latched-in during the rising edge of Serial Clock (C).
Then the memory contents, at that address, is shifted out on
Serial Data Output (DO), 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 8. The first byte
addressed can be at any location. The address is
automatically incremented to the next higher address after
each byte of data is shifted out. The whole memory can,
therefore, be read with a single Read Data Bytes (READ)
instruction. When the highest address is reached, the
address counter rolls over to 000000h, allowing the read
sequence to be continued indefinitely.
The Read Data Bytes (READ) instruction is terminated by
driving Chip Select ( S ) High. Chip Select ( S ) can be driven
High at any time during data output. Any Read Data Bytes
(READ) instruction, while an Erase, Program or Write cycle is
in progress, is rejected without having any effects on the
cycle that is in progress.

The Read Data Bytes at Higher Speed (FAST_READ)
The device is first selected by driving Chip Select ( S ) Low.
The instruction code for the Read Data Bytes at Higher

address (A23-A0) and a dummy byte, each bit being
latched-in during the rising edge of Serial Clock (C). Then the

Fast Read Dual Output (3Bh)
The Fast Read Dual Output (3Bh) instruction is similar to the
Fast Read (0Bh) instruction except the data is output on two
pins, DO and DIO, instead of just DO. This allows data to be
transferred from the A25L016 at twice the rate of standard
SPI devices.
Similar to the Fast Read instruction, the Fast Read Dual
Output instruction can operate at the highest possible
frequency of fC (See AC Characteristics). This is
accomplished by adding eight “dummy” clocks after the
24-bit address as shown in figure 10. The dummy clocks
allow the device’s internal circuits additional time for setting
up the initial address. The input data during the dummy
clocks is “don’t care”. However, the DIO pin should be
high-impedance prior to the falling edge of the first data out
clock.

Chip Erase (CE)
The Chip Erase (CE) 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).

is tCE) is initiated. While the Chip Erase cycle is in progress,
the Status Register may be read to check the value of the
Write In Progress (WIP) bit. The Write In Progress (WIP) bit is
1 during the self-timed Chip Erase cycle, and is 0 when it is
completed. At some unspecified time before the cycle is
completed, the Write Enable Latch (WEL) bit is reset.
The Chip Erase (CE) instruction is executed only if all Block

Deep Power-down (DP)
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
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 an extra
software protection mechanism, while the device is not in
active use, since in this mode, the device ignores all Write,
Program and Erase instructions.
Chip Select ( S ) Low, followed by the instruction code on
Serial Data Input (DIO). Chip Select ( S ) must be driven Low
for the entire duration of the sequence. The instruction
sequence is shown in Figure 16.
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
DC Characteristics Table.).
Chip Select ( S ) must be driven High after the eighth bit of the
instruction code has been latched in, otherwise the Deep
Power-down (DP) instruction is not executed. As soon as
Chip Select ( S ) is driven High, it requires a delay of tDP
before the supply current is reduced to ICC2 and the Deep
Power-down mode is entered.
Any Deep Power-down (DP) instruction, while an Erase,
Program or Write cycle is in progress, is rejected without
having any effects on the cycle that is in progress.
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 Signature (RES)
instruction also allows the Electronic Signature of the device
to be output on Serial Data Output (DO).

Read Device Identification (RDID)
This is followed by the 24-bit device identification, stored in
the memory, being shifted out on Serial Data Output (DO),
each bit being shifted out during the falling edge of Serial
Clock (C).
The Read Identification (RDID) instruction allows the 8-bit
manufacturer identification code to be read, followed by two
bytes of device identification. The manufacturer identification
is assigned by JEDEC, and has the value 37h. The device
identification is assigned by the device manufacturer, and
indicates the memory in the first bytes (30h), and the memory
capacity of the device in the second byte (15h for A25L016).
Any Read Identification (RDID) instruction while an Erase, or
Program cycle is in progress, is not decoded, and has no
effect on the cycle that is in progress.
The instruction sequence is shown in Figure 17. 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
Stand-by Power mode. Once in the Stand-by Power mode,
the device waits to be selected, so that it can receive, decode
and execute instructions.
The device is first selected by driving Chip Select ( S ) Low.
Then, the 8-bit instruction code for the instruction is shifted in.

POWER-UP AND POWER-DOWN
­ tPUW after VCC passed the VWI threshold
- tVSL afterVCC 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:
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
Usually a simple pull-up resistor on Chip Select ( S ) can be
used to insure safe and proper Power-up and Power-down.
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 value, 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), Block Erase (BE), Chip
Erase (CE) and Write Status Register (WRSR) instructions
until a time delay of tPUW has elapsed after the moment that
VCC rises above the VWI threshold. However, the correct
operation of the device is not guaranteed if, by this time, VCC
is still below VCC(min). No Write Status Register, Program or
Erase instructions should be sent until the later of:
The device is in the Standby mode (not the Deep
Power-down mode).
­ The Write Enable Latch (WEL) bit is reset.
Normal precautions must be taken for supply rail decoupling,
to stabilize the VCC feed. Each device in a system should
have the VCC rail decoupled by a suitable capacitor close to
the package pins. (Generally, this capacitor is of the order of
0.1µF).
At Power-down, when VCC drops from the operating voltage,
to below the POR threshold value, VWI, all operations are
disabled and the device does not respond to any instruction.
(The designer needs to be aware that if a Power-down occurs
while a Write, Program or Erase cycle is in progress, some
data corruption can result.)
