Unless an internal Program, Erase or Write Status Register
cycle is in progress, the device will be in the Standby mode
(this is not the Deep Power-down mode). Driving Chip Select
( S ) Low 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.
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 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.
Write Protect ( W ). The main purpose of this input signal is
to freeze the size of the area of memory that is protected
against program or erase instructions (as specified by the
values in the BP1 and BP0 bits of the Status Register).
SPI MODES
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
Page Programming
Status Register
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.
The Status Register contains a number of status and control
bits that can be read or set (as appropriate) by specific
instructions.
WIP bit. The Write In Progress (WIP) bit indicates whether
the memory is busy with a Write Status Register, Program or
Erase cycle.
WEL bit. The Write Enable Latch (WEL) bit indicates the
status of the internal Write Enable Latch, BP1, and BP0 bits.
The Block Protect (BP1, BP0) bits are non-volatile. They
define the size of the area to be software protected against
Program and Erase instructions.
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, BP1, BP0) become read-only bits.
Sector Erase and Bulk Erase
The Page Program (PP) instruction allows bits to be reset
from 1 to 0. Before this can be applied, the bytes of memory
need to have been erased to all 1s (FFh). This can be
achieved, a sector at a time, using the Sector Erase (SE)
instruction, or throughout the entire memory, using the Bulk
Erase (BE) instruction. This starts an internal Erase cycle (of
duration tSE or tBE).
The Erase instruction must be preceded by a Write Enable
(WREN) instruction.
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
A25L20P/A25L10P/A25L05P boasts the following data
protection mechanisms:
„ Power-On Reset and an internal timer (tPUW) can provide
protection against inadvertant 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
- Bulk Erase (BE) instruction completion
„ The Block Protect (BP1, BP0) bits allow part of the
memory to be configured as read-only. This is the
Software Protected Mode (SPM).
„ The Write Protect ( W ) signal allows the Block Protect
(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 inadvertant 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 or BE) can be achieved
by not waiting for the worst case delay (tW, tPP, tSE, or tBE). The
Write In Progress (WIP) bit is provided in the Status Register
so that the application program can monitor its value, polling it
to establish when the previous Write cycle, Program cycle or
Erase cycle is complete.
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 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 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.

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 5.
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 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), Bulk
Erase (BE), Write Status Register (WRSR), Write Enable
(WREN), Write Disable (WRDI) or Deep Power-down (DP)
instruction, Chip Select ( S ) must be driven High exactly at a
byte boundary, otherwise the instruction is rejected, and is not
executed. That is, Chip Select ( S ) must driven High when the
number of clock pulses after Chip Select ( S ) being driven Low
is an exact multiple of eight.
All attempts to access the memory array during a Write Status
Register cycle, Program cycle or Erase cycle are ignored, and
the internal Write Status Register cycle, Program cycle or
Erase cycle continues unaffected.

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.
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.
BP1, BP0 bits. The Block Protect (BP1, BP0) bits are
non-volatile. They define the size of the area to be software
protected against Program and Erase instructions. These bits
are written with the Write Status Register (WRSR) instruction.
When one or both of the Block Protect (BP1, BP0) bits is set
to 1, the relevant memory area (as defined in Table 1.)
becomes protected against Page Program (PP) and Sector
Erase (SE) instructions. The Block Protect (BP1, BP0) bits can
be written provided that the Hardware Protected mode has not
been set. The Bulk Erase (BE) instruction is executed if, and
only if, both Block Protect (BP1, BP0) bits are 0.

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 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 (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

The protection features of the device are summarized in Table
7.
When the Status Register Write Disable (SRWD) bit of the

(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

(WREN) instruction. (Attempts to write to the Status

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

Fast Read Dual Output (3Bh)
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.
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 A25L20P/A25L10P/A25L05P at twice
the rate of standard SPI devices.
Similar to the Fast Read instruction, the Fast Read Dual

software protection mechanism, while the device is not in
active use, since in this mode, the device ignores all Write,
Program and Erase instructions.
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 (DIO). Chip Select ( S ) must be driven Low
for the entire duration of the sequence. The instruction
sequence is shown in Figure 15.
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 32-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, plus the
continuation identification for AMIC Technology. The device
identification is assigned by the device manufacturer, and
indicates the memory in the first bytes (20h), and the memory
capacity of the device in the second byte (22h (Top) or 12h
(Bottom) for A25L20P, 21h(Top) or 11h(Bottom) for A25L10P,
20h(Top) or 10h(Bottom) for A25L05P).
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 16. 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 9.
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), Bulk Erase (BE) and Write
Status Register (WRSR) instructions until a time delay of tPUW
has elapsed after the moment that VCC rises above the VWI
threshold. However, the correct operation of the device is not
guaranteed if, by this time, VCC is still below VCC(min). No
Write Status Register, Program or Erase instructions should
be sent until the later of:
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.)
