Signal description
Signal description
See Figure 1: Logic diagram and Table 1: Signal names, for a brief overview of the signals
connected to this device.
3.1
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).
3.2
Serial Data input (D)
This input signal is used to transfer data serially into the device. It receives instructions,
addresses, and the data to be written. Values are latched on the rising edge of Serial Clock
(C).
3.3
Serial Clock (C)
This input signal provides the timing of the serial interface. Instructions, addresses, or data
present at Serial Data Input (D) are latched on the rising edge of Serial Clock (C). Data on
Serial Data Output (Q) changes after the falling edge of Serial Clock (C).
3.4
Chip Select (S)
When this input signal is high, the device is deselected and Serial Data Output (Q) is at high
impedance. Unless an internal write cycle is in progress, the device will be in the Standby
Power mode. 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.

Signal description
3.6
M95128, M95128-W, M95128-R
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.
3.7
VSS ground
VSS is the reference for the VCC supply voltage.
3.8
Supply voltage (VCC)
3.8.1
Operating supply voltage VCC
Prior to selecting the memory and issuing instructions to it, a valid and stable VCC voltage
within the specified [VCC(min), VCC(max)] range must be applied (see Table 7, Table 8 and
Table 9). 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 (tW). In
order to secure a stable DC supply voltage, it is recommended to decouple the VCC line with
a suitable capacitor (usually of the order of 10 nF to 100 nF) close to the VCC/VSS package
pins.
3.8.2
Device reset
In order to prevent 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 internal reset threshold voltage (this threshold is defined in DC tables 12, 13, 14
and 15 as VRES.
When VCC passes over the POR threshold, the device is reset and in the following state:
●
in Standby Power mode
●
deselected (note that, to be executed, an instruction must be preceded by a falling
edge on Chip Select (S))
●
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).
When VCC passes over the POR threshold, the device is reset and enters the Standby
Power mode. The device must not be accessed until VCC reaches a valid and stable VCC
voltage within the specified [VCC(min), VCC(max)] range defined in Table 7, Table 8 and
Table 9.

3.8.3
Signal description
Power-up conditions
When the power supply is turned on, VCC continuously rises from VSS to VCC. During this
time, the Chip Select (S) line is not allowed to float but should follow the VCC voltage. It is
therefore recommended to connect the S line to VCC via a suitable pull-up resistor (see
Figure 12).
In addition, the Chip Select (S) input offers a built-in safety feature, as it 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 VCC voltage has to rise continuously from 0 V up to the minimum VCC operating voltage
defined in Table 7, Table 8 and Table 9 and the rise time must not vary faster than 1 V/µs.
3.8.4
Power-down
During power-down (continuous decrease in the VCC supply voltage below the minimum
VCC operating voltage defined in Table 7, Table 8 and Table 9), the device must be:
●
deselected (Chip Select S should be allowed to follow the voltage applied on VCC)
●
in Standby Power mode (there should not be any internal write cycle in progress).

Operating features
4.1
Hold condition
The Hold (HOLD) signal is used to pause any serial communications with the device without
resetting the clocking sequence.
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 enter the Hold condition, the device must be selected, with Chip Select (S) low.
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 it is required to reset any processes that had
been in progress.
The Hold condition starts when the Hold (HOLD) signal is driven low at the same time as
Serial Clock (C) already being low (as shown in Figure 4).
The Hold condition ends when the Hold (HOLD) signal is driven high at the same time as
Serial Clock (C) already being low.
Figure 4 also shows what happens if the rising and falling edges are not timed to coincide
with Serial Clock (C) being low.

Operating features
Status Register
Figure 3 shows the position of the Status Register in the control logic of the device. The
Status Register contains a number of status and control bits that can be read or set (as
appropriate) by specific instructions. For a detailed description of the Status Register bits,
see Section 5.3: Read Status Register (RDSR).
4.3
Data Protection and protocol control
Non-volatile memory devices can be used in environments that are particularly noisy, and
within applications that could experience problems if memory bytes are corrupted.
Consequently, the device features the following data protection mechanisms:
●
Write 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
–
Write (WRITE) instruction completion
●
The Block Protect (BP1, BP0) bits in the Status Register allow part of the memory to be
configured as read-only.
●
The Write Protect (W) signal is used to protect the Block Protect (BP1, BP0) bits of 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 need to 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 5, 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 a the device to be deselected, by Chip Select (S) being driven
high.

Write Disable (WRDI)
One way of resetting the Write Enable Latch (WEL) bit is to send a Write Disable instruction
to the device.
As shown in Figure 6, 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 a the device to be deselected, by Chip Select
(S) being driven high.
The Write Enable Latch (WEL) bit, in fact, becomes reset by any of the following events:
●
Power-up
●
WRDI instruction execution
●
WRSR instruction completion
●
WRITE instruction completion.

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 Write 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 7.
The status and control bits of the Status Register are as follows:
5.3.1
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.
5.3.2
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.
5.3.3
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 4) 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.
5.3.4
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, 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.
The Write Status Register (WRSR) instruction is entered by driving Chip Select (S) low,
sending the instruction code followed by the data byte on Serial Data input (D), and driving
the Chip Select (S) signal 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 selftimed write cycle that takes tW to complete (as specified in Table 16, Table 17, Table 19 and
Table 19). The instruction sequence is shown in Figure 8.
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 tW, and, 0 when the write cycle is complete. The WEL bit (Write enable latch) is also
reset at the end of the write cycle tW.
The Write Status Register (WRSR) instruction allows 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 5.
●
The SRWD bit (Status register write disable bit), in accordance with the signal read on
the Write protect pin (W), allows the user to set or reset the write protection mode of the
Status Register itself, as shown in Table 5. When in the 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 tW write cycle.
The Write Status Register (WRSR) instruction has no effect on the b6, b5, b4, b1 and b0
bits in the Status Register. Bits b6, b5, b4 are always read as 0.

Instructions
The protection features of the device are summarized in Table 2.
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 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 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 (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 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
(BP1, BP0) bits in the Status Register, can be used.

Read from Memory Array (READ)
As shown in Figure 9, to send this instruction to the device, Chip Select (S) is first driven low.
The bits of the instruction byte and address bytes are then shifted in, on Serial Data Input
(D). The address is loaded into an internal address register, and the byte of data at that
address 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.
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 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.

Write to Memory Array (WRITE)
As shown in Figure 10, to send this instruction to the device, Chip Select (S) is first driven
low. The bits of the instruction byte, address byte, and at least one data byte are then shifted
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 rising edge of
Chip Select (S), continues for a period tWC (as specified in Table 16 to Table 19.), at the end
of which the Write in Progress (WIP) bit is reset to 0.
In the case of Figure 10, 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. If,
though, Chip Select (S) continues to be driven low, as shown in Figure 11., 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 the number of data bytes sent to the device exceeds the page
boundary, the internal address counter rolls over to the beginning of the page, and the
previous data there are overwritten with the incoming data. (The page size of these devices
is 64 bytes).
The instruction is not accepted, and is not executed, under the following conditions:
Note:
●
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 Chip Select (S) being driven high, 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.
The self-timed write cycle tW is internally executed as a sequence of two consecutive
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”.

5.6.1
ECC (error correction code) and write cycling
Most M95128, M95128-W and M95128-R devices offer an ECC (error correction code) logic
which compares each 4-byte word with 6 EEPROM bits of ECC (the list of concerned
devices is defined in Table 24: Available M95128x products (package, voltage range,
temperature grade)). As a result, if a single bit out of 4 bytes of data happens to be
erroneous during a read operation, the ECC detects it and replaces it by the correct value.
The read reliability is therefore improved by the use of this feature.
Note however that even if a single byte has to be written, 4 bytes are internally modified
(plus the ECC bits), that is, the addressed byte is cycled together with the three other bytes
making up the word. It is therefore recommended to write by packets of 4 bytes in order to
benefit from the larger amount of write cycles.
The maximum number of write cycles is qualified at 1 Million (1 000 000) write cycles, using
a cycling routine that writes to the device by multiples of 4-byte packets.

Connecting to the SPI bus
These devices are fully compatible with the SPI protocol.
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.

Figure 12 shows an example of three memory devices connected to an MCU, on an SPI
bus. 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 12) ensures that a device is not selected if the
bus master leaves the S line in the high impedance state.

Connecting to the SPI bus
M95128, M95128-W, M95128-R
In applications where the bus master might enter a state where all inputs/outputs SPI bus
would be 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 pulldown resistor so that, if all inputs/outputs become high impedance, the C line is pulled low
(while the S line is pulled high): this will ensure that S and C do not become high at the
same time, and so, that the tSHCH requirement is met. The typical value of R is 100 k.
7.1
SPI modes
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 falling edge of Serial Clock (C).
The difference between the two modes, as shown in Figure 13, 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)
