Functional description
Functional description
The M24SR64-Y device is a dynamic NFC/RFID tag that can be accessed either from the
I2C or the RF interface. The RF and I2C host can read or write to the same memory, that is
why only one host can communicate at a time with the M24SR64-Y. The management of
the interface selection is controlled by the M24SR64-Y device itself.
The RF interface is based on the ISO/IEC 14443 Type A standard. The M24SR64-Y is
compatible with the NFC Forum Type 4 Tag specifications and supports all corresponding
commands.
The I2C interface uses a two-wire serial interface consisting of a bidirectional data line and a
clock line. The devices carry a built-in 4-bit device type identifier code in accordance with
the I²C bus definition.
The device behaves as a slave in the I2C protocol.
Figure 1 displays the block diagram of the M24SR64-Y device.

Signal descriptions
2.1
Serial clock (SCL)
This input signal is used to strobe all data in and out of the device. In applications where this
signal is used by slave devices to synchronize the bus to a slower clock, the bus master
must have an open drain output, and a pull-up resistor must be connected from Serial clock
(SCL) to VCC. (Figure 17 indicates how the value of the pull-up resistor can be calculated).
In most applications, though, this method of synchronization is not employed, and so the
pull-up resistor is not necessary, provided that the bus master has a push-pull (rather than
open drain) output.
2.2
Serial data (SDA)
This bidirectional signal is used to transfer data in or out of the device. It is an open drain
output that may be wire-OR'ed with other open drain or open collector signals on the bus. A
pull-up resistor must be connected from Serial data (SDA) to VCC. (Figure 17 indicates how
the value of the pull-up resistor can be calculated).
2.3
Antenna coil (AC0, AC1)
These inputs are used to connect the device to an external coil exclusively. It is advised not
to connect any other DC or AC path to AC0 or AC1.
When correctly tuned, the coil is used to access the device using NFC Forum Type 4
commands.
2.4
Ground (VSS)
VSS, when connected, is the reference for the VCC supply voltage for all pads, even AC0
and AC1.
2.5
Supply voltage (VCC)
This pin can be connected to an external DC supply voltage.
Note:
An internal voltage regulator allows the external voltage applied on VCC to supply the
M24SR64-Y.
2.5.1
Operating supply voltage VCC
Prior to selecting the M24SR64-Y and issuing instructions to it, a valid and stable VCC
voltage within the specified [VCC(min), VCC(max)] range must be applied. To maintain a
stable DC supply voltage, it is recommended to decouple the VCC line with suitable
capacitors (usually of the order of 10 nF and 100 pF) close to the VCC/VSS package pins.
This voltage must remain stable and valid until the end of the transmission of the instruction
and, for a writing instruction (UpdateBinary, ChangeReferenceData,

EnableVerificationRequirement, DisableVerificationRequirement, EnablePermanentState,
DisablePermanentState, until the completion of the internal I²C write cycle (tW).
2.5.2
Power-up conditions
When the power supply is turned on, VCC rises from VSS to VCC. The VCC rise time must not
vary faster than 1V/µs.
2.5.3
Device reset in I²C mode
In order to prevent inadvertent write operations during power-up, a power-on reset (POR)
circuit is included. At power-up (continuous rise of VCC), the M24SR64-Y does not respond
to any I²C instruction until VCC has reached the power-on reset threshold voltage (this
threshold is lower than the minimum VCC operating voltage defined). When VCC passes
over the POR threshold, the device is reset and enters the Standby power mode. However,
the device must not be accessed until VCC has reached a valid and stable VCC voltage
within the specified [VCC(min), VCC(max)] range.
In a similar way, during power-down (continuous decrease in VCC), as soon as VCC drops
below the power-on reset threshold voltage, the M24SR64-Y stops responding to any
instruction sent to it.
2.5.4
Power-down conditions
During power-down (continuous decay of VCC), the M24SR64-Y must be in Standby power
mode (mode reached after decoding a Stop condition, assuming that there is no internal
operation in progress).
2.6
RF disable
This input signal is used to disable the RF communication. When the voltage on the VCC pin
is below the POR level or not connected, an internal pull-down resistor is connected on this
pad. Thus, the RF disable pad is maintained to the low level and the RF analog front end is
activated. When the voltage on the VCC pin is higher than the POR level, the I²C host shall
set this pin to enable or disable the RF communication. In Dual interface mode, RF disable
must not be left floating.
2.7
General purpose output (GPO)
The GPO pad is an open drain pad and a external pull-up resistor shall be connected to it.
This pad is a configurable output signal. On delivery, GPO is configured as Session opened.
Its behavior is consistent with the I2C or RF session activated and with the mode chosen by
the user. The GPO pad is enable when an RF or an I2C session is open. When neither an
RF nor an I2C session is open, the GPO is high impedance.

M24SR64-Y
The user can select one of these configurations(1):
2.7.1
•
SessionOpen: an RF or I2C session is ongoing.
•
MIP (NDEF Message updating In Progress): the RF host is writing an NDEF length
different from 0x0000. This mode can be used to detect when the RF host changes the
NDEF message as defined by the NFC Forum.
•
WIP (Writing In Progress): the M24SR64-Y is executing a writing operation.
•
INT (interrupt): the I2C or RF host can force the M24SR64-Y to send a negative pulse
on the GPO pin.
•
I2C ready response: an I2C response is ready to be read by the I²C host.
•
State mode: the I2C or RF host can control the state of the GPO pad during the RF
session.
•
RF busy: an RF host is communicating with the M24SR64-Y.
Session Open configuration (GPO field = 0xX1 or 0x1X)
When the GPO is configured as "Session Open", it goes to the Low state when an RF or I2C
session is ongoing (see Figure 3).
An RF session is taken when M24SR64-Y receives a valid Select Application. The session
is released after M24SR64-Y has received a valid Deselect command, if M24SR64-Y has
received a Kill RF session command in I2C or when the RF field became OFF.
An I2C session is taken when M24SR64-Y receives a valid Get session command or a valid
Kill RF session command. The session is released after M24SR64-Y has received I2C token
release sequence or after a Power Off.
GPO is driven low after a delay (1) or (3) when the session is open.
GPO is released after a delay (2) or (4) when the session is released.

3.3
Access right life time
The access right life time is validated while the NDEF file is selected or until the end of the
RF or I²C session. Once the read or write access right is granted, the host can send one or
more ReadBinary or UpdateBinary commands.
At the end of a session or when the host selects another file, the read and write access
rights are initialized.
3.4
NDEF file passwords
The NDEF file passwords protect the read or write access from an RF or I²C interface
from/to an NDEF file.
Two NDEF file passwords are available for each NDEF file:
•
Read password
•
Write password
The length of a password is 128 bits (16 bytes).

Communication mechanism
Communication mechanism
This chapter describes the principle of communication between an RF or an I2C host and
the M24SR64-Y device.
4.1
Master and slave
The M24SR64-Y acts as a slave device on either the I2C-bus or the RF channel and
therefore waits for a command from the I2C master or the RF host before sending its
response.
The RF host shall generate the RF field and the RF commands.
The I2C host shall supply the M24SR64-Y through the VCC pin and shall generate the I2C
clock on the SCL pad.
4.2
M24SR64-Y session mechanism
The M24SR64-Y is a dynamic NFC/RFID tag which can be accessed either from the RF or
I2C interface. The M24SR64-Y implements a token system. This token has two possible
values, RF or I2C. When the token exists and is assigned to one interface (RF or I2C), the
M24SR64-Y cannot communicate with the other host.
4.2.1
RF token
The token is given to the RF interface once the anticollision is done. The release condition
can be either an RF field cut-off, or the reception of the command deselect, or when the I²C
host sends the KillRFsession.
4.2.2
I2C token
The token is given to the I2C interface when the I2C host has sent the correct device Select.
The release condition can be either a power down condition on VCC pin or the reception of a
I2C token release sequence from the I2C host, after which M24SR64-Y goes in Standby
power mode.

M24SR64-Y
I²C and RF command sets
The command sets of the M24SR64-Y can be split in different command families. Most
commands are common between the RF and the I²C interface. Some commands are
specific to the RF interface and some others are specific to the I²C interface. This section
describes the M24SR64-Y command sets that can be issued by the RF or the I²C host.
There are three command families:
•
the NFC Forum Type 4 Tag command set
•
the ISO/IEC 7816-4 command set
•
the proprietary command set
The NFC Forum Type 4 Tag command set and the ISO/IEC 7816-4 command set use the IBlock format. For more details about the I-Block format, refer to Section 5.2: I-Block format.
Two other command formats exist:
•
the commands using the R-Block format
•
the commands using the S-Block format
For more details about these formats, refer to the corresponding sections: Section 5.3: RBlock format and Section 5.4: S-Block format.
This section gives a brief description of the RF and I²C host common commands. The
format of these command sets is the I-Block format.

Structure of the command sets
The exchange of data between the RF or the I²C host and the M24SR64-Y uses three kinds
of data formats, called blocks:
Note:
•
I-Block: to exchange the command and the response
•
R-Block: to exchange positive or negative acknowledgment
•
S-Block: to use either the Deselect command or the Frame Waiting eXtension (WTX)
command or response
max WTX value = 0x0B
This section describes the structure of the I-Block, R-block and S-Block. This format is used
for the application command set.
5.2
I-Block format
The I-Block is used to exchange data between the RF or the I²C host and the M24SR64-Y.
It is composed of three fields. Table 15 details the I-Block format.

Note:
After receiving the deselect command, the session is released and M24SR64-Y enters the
Standby power mode. In I2C, the session is released after executing the I2C token release
sequence.
In response to a RATS command, M24SR64-Y returns FWI parameter (default frame waiting
time used); when M24SR64-Y needs more time for a command execution, it requests a
frame waiting time extension by responding 0xF2 0xWTX (Request waiting time = FWI *
WTX). If the reader accepts M24SR64-Y request, it acknowledges by sending the command
0xF2 0xWTX. The frame waiting time becomes FWI * WTX for the current command only.
5.5
CRC of the I2C and RF frame
The two CRC bytes check the data transmission between the RF host or I²C host and the
M24SR64-Y. For the RF frame, the CRC is computed on all the data bits in the frame,
excluding parity bits, SOF and EOF, and the CRC itself.
For the I²C frames, the CRC is computed on all data bits of the frame excluding Device
select and the CRC itself.
The CRC is as defined in ISO/IEC 13239. The initial register content shall be 0x6363 and
the register content shall not be inverted after calculation.

ReadBinary command
On receiving the ReadBinary command, the M24SR64-Y reads the requested memory field
and sends back its value in the R-APDU response.
Before sending a ReadBinary command, a file shall be selected by using a Select
command.
The Response of the ReadBinary command is successful when the data to be read is within
the selected file (1); in other words, when the sum of P1-P2 and Le fields is equal to or lower
than the selected file length.

I²C and RF command sets
ISO/IEC 7816-4 commands
The ISO/IEC 7816-4 command set offers some extended features such as the protection of
the NDEF file. This command set is used to manage the right access of the NDEF file.
5.7.1
Verify command
The Verify command has two functions:
1.
Check if a password is required to access to the NDEF file (the LC field = 0x00).
2.
Check that the password embedded in the Verify command allows the access to the
memory (the Lc field = 0x10 and the password is present).
When the Lc field if equal to 0x00, the verify command returns a success code (0x90 00)
provided that the access to the NDEF file does not require a password. When the access to
the NDEF file is protected, the response to the Verify command returns an error code
(0x63 00).
When the Lc field equals 0x10, on receiving the Verify command, the M24SR64-Y
compares the requested password with the data contained in the request and reports
whether the operation has been successful in the response.
Before sending this command, an NDEF file shall be selected by issuing the NDEF Select
command. Thus, this command checks the right access condition of the last NDEF file
selected.
After a successful command, an access is granted for the whole NDEF file.

The Change Reference Data command replaces the read or write password related to the
NDEF files previously selected. It can be performed only if the security status satisfies the
security attributes for this command.
Before sending this command, the verify command with the correct NDEF write password
shall be issued. Thus, this command changes the reference data of the NDEF file.

Enable Verification Requirement command
The Enable Verification Requirement command activates the protection by password of the
NDEF file. When this command is successful, the read or write access to the NDEF file is
protected by a 128-bit password. It can be performed only if the security status satisfies the
security attributes for this command.
This command can update the right access of the NDEF file by writing into the EEPROM. In
this case, the response timing will be around 5 ms.
Before sending this command, the verify command with the correct NDEF write password
shall be issued. Thus, this command changes the access right of the NDEF file.

The FSCI codes the FSC which stands for the maximum frame size that the M24SR64-Y is
able to receive. The M24SR64-Y is able to receive up to 256 bytes of command. If the RF or
I²C host sends a command with more than 256 bytes, the M24SR64-Y will not be able to
treat the command and will not reply.
The FWI which stands for the Frame Waiting time Integer codes the FWT. This time
corresponds to the maximum duration while an RF or I²C host shall send before sending the
next command.

Anticollision and Device Activation command set for the RF
interface
The M24SR64-Y device supports the command set defined in the NFC-A Technology and
the Type 4A Tag Platform chapters of the NFC Digital Protocol V1.0 specification.
6.2
Open an RFsession
Once the RF host has terminated the anticollision procedure and retrieve the ATS response,
it shall send the SelectApplication command. The M24SR64-Y will open an RF session. At
this point, the RF host can send the applicative command set and the I²C cannot
communicate with the M24SR64-Y without closing first the RF session using the I2C
KillRFsession command.
6.3
Close an RFsession
The RF host can close the RF session by issuing one of these methods:
6.4
•
send an S(DES) command
•
turn off the RF field
Applicative command set
The applicative command set is composed of the following command sets:

I2C device operation
I2C device operation
The M24SR64-Y device supports the I2C protocol. The device that controls the data transfer
is known as the bus master, and the other one as the slave device. A data transfer can only
be initiated by the bus master, which also provides the serial clock for synchronization. The
M24SR64-Y device is a slave in all communications.
7.1
I2C communication protocol
The I2C communication is built on a system of command and reply exchange. The I2C host
starts the communication by sending a request. Once a valid request is received by the
M24SR64-Y device, it carries out an internal operation and creates its answer.
As defined in this document, and except for the GetI2C session and Kill RF session
commands, the definition of a valid request is a command with a right CRC value.
Figure 12 shows an exchange of a command and a response between the I²C host and the
M24SR64-Y. Once the I²C session is open, the I²C host can send a command. The
command is composed of:
•
a Device Select field with the R/W bit set to 0.
•
the command field.
The M24SR64-Y acknowledges on the reception of each byte.
Once the M24SR64-Y is ready to send the answer, the I²C host shall:
•
send a Device Select field with the R/W bit set to 1.
•
release the SDA line and send an SCL clock.
The I²C host shall acknowledge on the reception of each byte.

Note:
A restart during a command and response exchange is not supported by the M24SR64-Y.
After a command, the I2C host can execute a Polling sequence to determine when the
response is available.
Polling sequence: Loop on < START (S) + DeviceSelect with RW=0 + read NACK/ACK
+ STOP (P) >
The response is available as soon as the M24SR64-Y sends an ACK ( host read will a
'0').

I2C device operation
7.2
M24SR64-Y
Start condition
A Start condition is identified by a falling edge of serial data (SDA) while the serial clock
(SCL) is stable in the high state. A Start condition must precede any data transfer command.
The device continuously monitors (except during an instruction processing) the SDA and the
SCL for a Start condition, and does not respond unless one is given.
7.3
Stop condition
A Stop condition is identified by a rising edge of serial data (SDA) while the serial clock
(SCL) is stable and driven high. A Stop condition terminates a command between the device
and the bus master.
7.4
I²C token release sequence
As explained in the M24SR64-Y session mechanism, the I²C communication is reserved to
the I²C host when the session token has the I²C value.
The following sequence explains how to release the I²C value of the session token.
I²C communication with the M24SR64-Y starts with a valid Start condition, followed by a
device select code.
If the delay between the Start condition and the following rising edge of the Serial Clock
(SCL) that samples the most significant of the Device Select exceeds the tSTART_OUT_MAX
time (see Table 78), the I²C logic block is reset and further incoming data transfer is ignored
until the next valid Start condition.

Note:

If the above delay is below tSTART_OUT_min (see Table 78), I2C session token stays
unmodified.
If the delay is between tSTART_OUT_min and tSTART_OUT_max, I2C session token might or not
be released. This range of delay is not authorized for safe operation.
DocID023790 Rev 20

7.5
I2C device operation
I²C timeout on clock period
During a data transfer on the I2C bus, if the serial clock high pulse or serial clock low pulse
exceeds tCL_RESET value that is the maximum value specified in Table 78, the I2C logic
block is reset and any further incoming data transfer is ignored until the next valid Start
condition.
If the serial clock high pulse is under the maximum value of tCHCL and the serial clock low
pulse is under the maximum value of tCLCH in Table 78, the I2C logic block is not reset.
For proper operation, the serial clock high pulse should not be higher than tCHCL and lesser
than tCL_RESET, and the serial clock low pulse should not be higher than tCHCH and lesser
tCL_RESET.
7.6
Acknowledge bit (ACK)
The acknowledge bit is used to indicate a successful byte transfer. The bus transmitter,
whether a bus master or a slave device, releases the serial data (SDA) after sending eight
bits of data. During the 9th clock pulse period, the receiver pulls the SDA low to
acknowledge the receipt of the eight data bits.
7.7
Data input
During data input, the device samples serial data (SDA) on the rising edge of the serial clock
(SCL). For a correct device operation, the SDA must be stable during the rising edge of the
SCL, and the SDA signal must change only when the SCL is driven low.
7.8
I²C device address
The device address is the concatenation of the group number coded on 4 bits and the I2C

SDA.
5. tCLQV is the time (from the falling edge of SCL) required by the SDA bus line to reach 0.8VCC in a compatible way with the
I2C specification (which specifies tSU:DAT (min) = 100 ns), assuming that the Rbus × Cbus time constant is less than 500 ns
