described next.
3.1
3.2
Serial Data Output (Q)
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).
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 written. Values are latched on the rising edge of Serial Clock
(C).
3.3
3.4
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) change from the falling edge of Serial Clock (C).
Chip Select (S)
When this input signal is high, the device is deselected and Serial Data Output (Q) is at high
impedance. The device is in the Standby Power mode, unless an internal Write cycle is in
progress. Driving Chip Select (S) low selects the device, placing it in the Active Power
mode.
After power-up, a falling edge on Chip Select (S) is required prior to the start of any
instruction.
3.5
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 (Q) is high impedance, and Serial Data
Input (D) and Serial Clock (C) are Don’t Care.
To start the Hold condition, the device must be selected, with Chip Select (S) driven low.

Write Protect (W)
The main purpose of this input signal is to freeze the size of the area of memory that is
protected against Write instructions (as specified by the values in the BP1 and BP0 bits of
the Status Register).
This pin must be driven either high or low, and must be stable during all Write instructions.

All instructions, addresses and input data bytes are shifted in to the device, most significant
bit first. The Serial Data Input (D) is sampled on the first rising edge of the Serial Clock (C)
after Chip Select (S) goes low.
All output data bytes are shifted out of the device, most significant bit first. The Serial Data
Output (Q) is latched on the first falling edge of the Serial Clock (C) after the instruction
(such as the Read from Memory Array and Read Status Register instructions) have been
clocked into the device.

1. The Write Protect (W) and Hold (HOLD) signals should be driven, high or low as appropriate.
Figure 5 shows an example of three memory devices connected to an SPI bus master. Only
one memory device is selected at a time, so only one memory device drives the Serial Data
Output (Q) line at a time. The other memory devices are high impedance.
The pull-up resistor R (represented in Figure 5) ensures that a device is not selected if the
Bus Master leaves the S line in the high impedance state.
In applications where the Bus Master may leave all SPI bus lines in high impedance at the
same time (for example, if the Bus Master is reset during the transmission of an instruction),
the clock line (C) must be connected to an external pull-down resistor so that, if all
inputs/outputs become high impedance, the C line is pulled low (while the S line is pulled
high): this ensures that S and C do not become high at the same time, and so, that the
t
requirement is met. The typical value of R is 100 kΩ.

SPI modes
These devices can be driven by a microcontroller with its SPI peripheral running in either of
the following two modes:
•
•
CPOL=0, CPHA=0
CPOL=1, CPHA=1
For these two modes, input data is latched in on the rising edge of Serial Clock (C), and
output data is available from the falling edge of Serial Clock (C).
The difference between the two modes, as shown in Figure 6, 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)

Operating features
5.1
Supply voltage (VCC)
5.1.1
Operating supply voltage (V )
CC
Prior to selecting the memory and issuing instructions to it, a valid and stable V voltage
CC
within the specified [V (min), V (max)] range must be applied (see Operating conditions
CC
CC
in Section 9: DC and AC parameters). This voltage must remain stable and valid until the
end of the transmission of the instruction and, for a Write instruction, until the completion of
the internal write cycle (t ). In order to secure a stable DC supply voltage, it is
W
recommended to decouple the V line with a suitable capacitor (usually of the order of
CC
10 nF to 100 nF) close to the V /V device pins.
CC SS
5.1.2
Device reset
In order to prevent erroneous instruction decoding and inadvertent Write operations during
power-up, a power-on-reset (POR) circuit is included. At power-up, the device does not
respond to any instruction until VCC reaches the POR threshold voltage. This threshold is
lower than the minimum V operating voltage (see Operating conditions in Section 9: DC
CC
and AC parameters).
At power-up, when V passes over the POR threshold, the device is reset and is in the
CC
following state:
•
•
•
in Standby Power mode,
deselected,
Status Register values:
–
–
–
The Write Enable Latch (WEL) bit is reset to 0.
The Write In Progress (WIP) bit is reset to 0.
The SRWD, BP1 and BP0 bits remain unchanged (non-volatile bits).
It is important to note that the device must not be accessed until V reaches a valid and
CC
stable level within the specified [V (min), V (max)] range, as defined under Operating
CC
CC
conditions in Section 9: DC and AC parameters.
5.1.3
Power-up conditions
When the power supply is turned on, V rises continuously from V to V . During this
CC
SS
CC
time, the Chip Select (S) line is not allowed to float but should follow the V voltage. It is
CC
therefore recommended to connect the S line to V via a suitable pull-up resistor (see
CC
Figure 5).
In addition, the Chip Select (S) input offers a built-in safety feature, as the S input is edge-
sensitive as well as level-sensitive: after power-up, the device does not become selected
until a falling edge has first been detected on Chip Select (S). This ensures that Chip Select
(S) must have been high, prior to going low to start the first operation.
The V voltage has to rise continuously from 0 V up to the minimum V operating voltage
CC
CC
defined under Operating conditions in Section 9: DC and AC parameters, and the rise time
must not vary faster than 1 V/µs.

5.1.4
Power-down
During power-down (continuous decrease of the V supply voltage below the minimum
CC
V
operating voltage defined under Operating conditions in Section 9: DC and AC
CC
parameters), the device must be:
•
•
deselected (Chip Select S should be allowed to follow the voltage applied on V ),
CC
in Standby Power mode (there should not be any internal write cycle in progress).
5.2
Active Power and Standby Power modes
When Chip Select (S) is low, the device is selected, and in the Active Power mode. The
device consumes I
.
CC
When Chip Select (S) is high, the device is deselected. If a Write cycle is not currently in
progress, the device then goes into the Standby Power mode, and the device consumption
drops to I
, as specified in DC characteristics (see Section 9: DC and AC parameters).
CC1
5.3
Hold condition
The Hold (HOLD) signal is used to pause any serial communications with the device without
resetting the clocking sequence.
To enter the Hold condition, the device must be selected, with Chip Select (S) low.
During the Hold condition, the Serial Data Output (Q) is high impedance, and the Serial Data
Input (D) and the Serial Clock (C) are Don’t Care.
Normally, the device is kept selected for the whole duration of the Hold condition.
Deselecting the device while it is in the Hold condition has the effect of resetting the state of
the device, and this mechanism can be used if required to reset any processes that had
(a) (b)
been in progress.

a. This resets the internal logic, except the WEL and WIP bits of the Status Register.
b. In the specific case where the device has shifted in a Write command (Inst + Address + data bytes, each data
byte being exactly 8 bits), deselecting the device also triggers the Write cycle of this decoded command.

Operating features
The Hold condition starts when the Hold (HOLD) signal is driven low when Serial Clock (C)
is already low (as shown in Figure 7).
Figure 7 also shows what happens if the rising and falling edges are not timed to coincide
with Serial Clock (C) being low.

5.5
Status Register
The Status Register contains a number of status and control bits that can be read or set (as
appropriate) by specific instructions. See Section 6.3: Read Status Register (RDSR) for a
detailed description of the Status Register bits.
Data protection and protocol control
The device features the following data protection mechanisms:
•
Before accepting the execution of the Write and Write Status Register instructions, the
device checks whether the number of clock pulses comprised in the instructions is a
multiple of eight.
•
•
•
All instructions that modify data must be preceded by a Write Enable (WREN)
instruction to set the Write Enable Latch (WEL) bit.
The Block Protect (BP1, BP0) bits in the Status Register are used to configure part of
the memory as read-only.
The Write Protect (W) signal is used to protect the Block Protect (BP1, BP0) bits in the
Status Register.
For any instruction to be accepted, and executed, Chip Select (S) must be driven high after
the rising edge of Serial Clock (C) for the last bit of the instruction, and before the next rising
edge of Serial Clock (C).
Two points should be noted in the previous sentence:
•
The “last bit of the instruction” can be the eighth bit of the instruction code, or the eighth
bit of a data byte, depending on the instruction (except for Read Status Register
(RDSR) and Read (READ) instructions).
•
The “next rising edge of Serial Clock (C)” might (or might not) be the next bus
transaction for some other device on the SPI bus.

Write Enable (WREN)
The Write Enable Latch (WEL) bit must be set prior to each WRITE and WRSR instruction.
The only way to do this is to send a Write Enable instruction to the device.
As shown in Figure 8, to send this instruction to the device, Chip Select (S) is driven low,
and the bits of the instruction byte are shifted in, on Serial Data Input (D). The device then
enters a wait state. It waits for the device to be deselected, by Chip Select (S) being driven
high.

The status and control bits of the Status Register are as follows:
6.3.1
6.3.2
WIP bit
The Write In Progress (WIP) bit indicates whether the memory is busy with a Write or Write
Status Register 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 or Write Status Register instruction is accepted.
The WEL bit is returned to its reset state by the following events:
•
•
•
•
Power-up
Write Disable (WRDI) instruction completion
Write Status Register (WRSR) instruction completion

6.3.3
BP1, BP0 bits
The Block Protect (BP1, BP0) bits are non volatile. They define the size of the area to be
software-protected against Write instructions. These bits are written with the Write Status
Register (WRSR) instruction. When one or both of the Block Protect (BP1, BP0) bits is set
to 1, the relevant memory area (as defined in Table 2) becomes protected against Write
(WRITE) instructions. The Block Protect (BP1, BP0) bits can be written provided that the
Hardware Protected mode has not been set.

Write Status Register (WRSR)
The Write Status Register (WRSR) instruction is used to write new values to the Status
Register. Before it can be accepted, a Write Enable (WREN) instruction must have been
previously executed.
The Write Status Register (WRSR) instruction is entered by driving Chip Select (S) low,
followed by the instruction code, the data byte on Serial Data input (D) and Chip Select (S)
driven high. Chip Select (S) must be driven high after the rising edge of Serial Clock (C) that
latches in the eighth bit of the data byte, and before the next rising edge of Serial Clock (C).
Otherwise, the Write Status Register (WRSR) instruction is not executed.

Driving the Chip Select (S) signal high at a byte boundary of the input data triggers the self-
timed Write cycle that takes t to complete (as specified in AC tables under Section 9: DC
W
and AC parameters).
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 WIP bit is 1 during the self-timed
Write cycle t , and 0 when the Write cycle is complete. The WEL bit (Write Enable Latch) is
W
also reset at the end of the Write cycle t .
W
The Write Status Register (WRSR) instruction enables the user to change the values of the
BP1, BP0 and SRWD bits:
•
The Block Protect (BP1, BP0) bits define the size of the area that is to be treated as
read-only, as defined in Table 2.
•
The SRWD (Status Register Write Disable) bit, in accordance with the signal read on
the Write Protect pin (W), enables the user to set or reset the Write protection mode of
the Status Register itself, as defined in Table 6. When in Write-protected mode, the
Write Status Register (WRSR) instruction is not executed.
The contents of the SRWD and BP1, BP0 bits are updated after the completion of the
WRSR instruction, including the t Write cycle.
W
The Write Status Register (WRSR) instruction has no effect on the b6, b5, b4, b1, b0 bits in
the Status Register. Bits b6, b5, b4 are always read as 0.

The protection features of the device are summarized in Table 6.
When the Status Register Write Disable (SRWD) bit in the Status Register is 0 (its initial
delivery state), it is possible to write to the Status Register (provided that the WEL bit has
previously been set by a WREN instruction), regardless of the logic level applied on the
Write Protect (W) input pin.
When the Status Register Write Disable (SRWD) bit in the Status Register is set to 1, two
cases should be considered, depending on the state of the Write Protect (W) input pin:
•
If Write Protect (W) is driven high, it is possible to write to the Status Register (provided
that the WEL bit has previously been set by a WREN instruction).
•
If Write Protect (W) is driven low, it is not possible to write to the Status Register even if
the WEL bit has previously been set by a WREN instruction. (Attempts to write to the
Status Register are rejected, and are not accepted for execution). As a consequence,
all the data bytes in the memory area, which are Software-protected (SPM) by the
Block Protect (BP1, BP0) bits in 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:
•
•
either setting the SRWD bit after driving the Write Protect (W) input pin low,
or driving the Write Protect (W) input pin low after setting the SRWD bit.
Once the Hardware-protected mode (HPM) has been entered, the only way of exiting it is to
pull high the Write Protect (W) input pin.
If the Write Protect (W) input pin is permanently tied high, the Hardware-protected mode
(HPM) can never be activated, and only the Software-protected mode (SPM), using the
Block Protect (BP1, BP0) bits in the Status Register, can be used.

If Chip Select (S) continues to be driven low, the internal address register is incremented
automatically, and the byte of data at the new address is shifted out.
When the highest address is reached, the address counter rolls over to zero, allowing the
Read cycle to be continued indefinitely. The whole memory can, therefore, be read with a
single READ instruction.
The Read cycle is terminated by driving Chip Select (S) high. The rising edge of the Chip
Select (S) signal can occur at any time during the cycle.
The instruction is not accepted, and is not executed, if a Write cycle is currently in progress.

in, on Serial Data Input (D).
The instruction is terminated by driving Chip Select (S) high at a byte boundary of the input
data. The self-timed Write cycle, triggered by the Chip Select (S) rising edge, continues for a
period t (as specified in AC characteristics in Section 9: DC and AC parameters), at the
W
end of which the Write in Progress (WIP) bit is reset to 0.

In the case of Figure 13, Chip Select (S) is driven high after the eighth bit of the data byte
has been latched in, indicating that the instruction is being used to write a single byte.
However, if Chip Select (S) continues to be driven low, as shown in Figure 14, the next byte
of input data is shifted in, so that more than a single byte, starting from the given address
towards the end of the same page, can be written in a single internal Write cycle.
Each time a new data byte is shifted in, the least significant bits of the internal address
counter are incremented. If more bytes are sent than will fit up to the end of the page, a
condition known as “roll-over” occurs. In case of roll-over, the bytes exceeding the page size
are overwritten from location 0 of the same page.
The instruction is not accepted, and is not executed, under the following conditions:
•
if the Write Enable Latch (WEL) bit has not been set to 1 (by executing a Write Enable
instruction just before),
•
•
if a Write cycle is already in progress,
if the device has not been deselected, by driving high Chip Select (S), at a byte
boundary (after the eighth bit, b0, of the last data byte that has been latched in),
•
if the addressed page is in the region protected by the Block Protect (BP1 and BP0)
bits.
Note:
The self-timed write cycle t is internally executed as a sequence of two consecutive
W
events: [Erase addressed byte(s)], followed by [Program addressed byte(s)]. An erased bit
is read as “0” and a programmed bit is read as “1”.

6.6.1
Cycling with Error Correction Code (ECC)
M95512 and M95512-D devices offer an Error Correction Code (ECC) logic. The ECC is an
internal logic function which is transparent for the SPI communication protocol.
(c)
The ECC logic is implemented on each group of four EEPROM bytes . Inside a group, if a
single bit out of the four bytes happens to be erroneous during a Read operation, the ECC
detects this bit and replaces it with the correct value. The read reliability is therefore much
improved.
Even if the ECC function is performed on groups of four bytes, a single byte can be
written/cycled independently. In this case, the ECC function also writes/cycles the three
(c)
other bytes located in the same group . As a consequence, the maximum cycling budget is
defined at group level and the cycling can be distributed over the four bytes of the group: the
sum of the cycles seen by byte0, byte1, byte2 and byte3 of the same group must remain
below the maximum value defined in Table 12.
c. A group of four bytes is located at addresses [4*N, 4*N+1, 4*N+2, 4*N+3], where N is an integer.

Read Identification Page (available only in M95512-D
devices)
The Identification Page (128 bytes) is an additional page which can be written and (later)
permanently locked in Read-only mode.
Reading this page is achieved with the Read Identification Page instruction (see Table 3).
The Chip Select signal (S) is first driven low, the bits of the instruction byte and address
bytes are then shifted in, on Serial Data Input (D). Address bit A10 must be 0, upper address
bits are Don't Care, and the data byte pointed to by the lower address bits [A6:A0] is shifted
out on Serial Data Output (Q). If Chip Select (S) continues to be driven low, the internal
address register is automatically incremented, and the byte of data at the new address is
shifted out.
The number of bytes to read in the ID page must not exceed the page boundary, otherwise
unexpected data is read (e.g.: when reading the ID page from location 90d, the number of
bytes should be less than or equal to 38d, as the ID page boundary is 128 bytes).
The read cycle is terminated by driving Chip Select (S) high. The rising edge of the Chip
Select (S) signal can occur at any time during the cycle. The first byte addressed can be any
byte within any page.
The instruction is not accepted, and is not executed, if a write cycle is currently in progress.

Read Lock Status (available only in M95512-D devices)
The Read Lock Status instruction (see Table 3) is used to check whether the Identification
Page is locked or not in Read-only mode. The Read Lock Status sequence is defined with
the Chip Select (S) first driven low. The bits of the instruction byte and address bytes are
then shifted in on Serial Data Input (D). Address bit A10 must be 1, all other address bits are
Don't Care. The Lock bit is the LSB (least significant bit) of the byte read on Serial Data
Output (Q). It is at “1” when the lock is active and at “0” when the lock is not active. If Chip
Select (S) continues to be driven low, the same data byte is shifted out. The read cycle is
terminated by driving Chip Select (S) high.
The instruction sequence is shown in figure below.

Lock ID (available only in M95512-D devices)
The Lock ID instruction permanently locks the Identification Page in read-only mode. Before
this instruction can be accepted, a Write Enable (WREN) instruction must have been
executed.
The Lock ID instruction is issued by driving Chip Select (S) low, sending the instruction
code, the address and a data byte on Serial Data Input (D), and driving Chip Select (S) high.
In the address sent, A10 must be equal to 1, all other address bits are Don't Care. The data
byte sent must be equal to the binary value xxxx xx1x, where x = Don't Care.
Chip Select (S) must be driven high after the rising edge of Serial Clock (C) that latches in
the eighth bit of the data byte, and before the next rising edge of Serial Clock (C).
Otherwise, the Lock ID instruction is not executed.
Driving Chip Select (S) high at a byte boundary of the input data triggers the self-timed write
cycle whose duration is t (as specified in AC characteristics in Section 9: DC and AC
W
parameters). The instruction sequence is shown in Figure 18.
The instruction is discarded, and is not executed, under the following conditions:
•
•
•
If a Write cycle is already in progress,
If the Block Protect bits (BP1,BP0) = (1,1),
If a rising edge on Chip Select (S) happens outside of a byte boundary.
