1.3 Operation Mode
This RFID provides three operation modes of RF communication, serial communication, and tunnel.
Figure 1-2 gives the overview of each operation mode.
■ RF communication mode
This mode is used for communication between reader/writer and RFID. Reader/writer is the master and RFID
is the slave. Key commands are read and write commands to FeRAM of RFID. This mode allows batteryless
operations that use only the power supplied from the antenna of reader/writer.
For more information about RF communication mode, see Chapter 4 RF Communication Mode.
■ Serial communication mode
This mode is used for communication between host and RFID. Host is the master and RFID is the slave. Key
commands are read and write commands to FeRAM of RFID. This mode requires a power supply to the
supply voltage pin (VDDEX) of RFID.
For more information about serial communication mode, see Chapter 5 Serial Communication Mode.
■ Tunnel mode
This mode is used for communication between reader/writer and host via RFID. Reader/writer is the master
and host is the slave. Key commands are read and write commands to host. This mode requires a power
supply to the supply voltage pin (VDDEX) of RFID.
For more information about serial communication mode, see Chapter 7 Tunnel Mode.
Additionally, for state transition diagram in each operation mode, see Section 8.2 State Transition Diagram
in Operation Mode.

1.4 Encrypted Communication Function
This RFID provides an encrypted communication function.
Figure 1-3 depicts its functionality in each operation mode.
For communication between reader/writer and RFID, RF communication mode allows both encrypted and
plaintext (unencrypted) communications while serial communication mode allows only plaintext
communication.
Tunnel mode enables both encrypted and plaintext communications between reader/writer and RFID.
However, for communication between RFID and host, the mode enables only plaintext communication,
regardless of communication form (encrypted or plaintext) between reader/writer and RFID.
Encrypted communication uses Message Authentication Code (MAC) to detect falsified communication data
and to prevent access from illegal readers/writers.

2.2 Pin Descriptions
■ Coil connection pins (VA, VB)
Used for connecting an antenna coil. Also connect a resonance capacitor for adjusting resonance frequency.
■ Ground (VSS)
A reference power supply pin. Connect to the ground of the host CPU.
■ Internal analog power supply (VDDA)
An internal analog power supply pin. Connect a capacitor (see the Product Standards for its value) between
VDDA and VSS pins as close as possible to the RFID. It is unnecessary to apply an external power to this pin.
■ Contact power supply (VDDEX)
A contact power supply pin. Apply a "high" voltage to this pin when communicating data between the host
CPU and RFID. Connect a capacitor (see the Product Standards for its value) between VDDEX and VSS pins
as close as possible to the RFID.
Additionally, the RFID has a built-in clamp circuit for 5-V operation. When using the circuit, apply a 5-V supply
voltage to this pin through a given resistor (see the Product Standards for its value).
■ Host interface I2C (SDA, SCL)
I2C is an N-ch open drain pin, so should be pulled up to VDDEX externally. It is available between the
frequencies 20 kHz and 100 kHz. Start the access tBoot after applying VDDEX. For more information about
tBoot, see the Product Standards.
■ Interrupt request (NIQR)
An N-ch open drain pin to request an interrupt to the host and should be pulled up externally.
Chapter 2 Pin Descriptions
19
2.3 Connection Example
Figure 2-3 gives a connection example.
This example shows that the host's GPIO controls the RFID's VDDEX. In this case, when not using serial
communication, turning VDDEX off allows the consumption current of the RFID to be turned off. In addition, it
is also possible to supply a voltage to VDDEX directly from the power supply, not from the host's GPIO.
The SDA(IO) and NIRQ pins are open-drain output. Pull up these pins to the same voltage level as the power
supply of the host.
Please arrange the capacity between power supplies of VDDA near the PKG as much as possible.

QWT
AWT
QWT
QWT specifies the maximum wait time until the RFID receives a QUERY command from the host after it
sends an IRQ to the host during tunnel mode operation.
QWT is determined using the following formula.
Maximum wait time for QUERY command = T × 2QWT
T: Typ. 1024 μs (±25%)
QWT: 0 to 8 (default: 4; typ. approximately 16 ms)
When this field is set to a value other than 0 to 8, a default value will be applied.
AWT
AWT specifies the maximum wait time until the RFID receives an ANSWER command from the host after it
sends a response to the QUERY command to the host during tunnel mode operation.
AWT is determined using the following formula.
Maximum wait time for ANSWER command = T × 2AWT
T: typ. 1024 μs (±25%)
AWT: 0 to 12 (default: 7; typ. approximately 131 ms )
When this field is set to a value other than 0 to 12, a default value will be applied.
Note: T includes an error of ±25%. Set the QWT and AWT values in consideration of the error.
■ HW2 (1 byte)

INTWT
INTWT specifies the maximum wait time between characters in I2C communication.
INTWT is determined using the following formula.
Maximum wait time between characters = T × 2INTWT
T: Typ. 942 μs (±25%)
INTWT: 0 to 3 (default: 3; typ. approximately 7.5ms )
When this field is set to a value other than 0 to 8, a default value will be applied.
RESWT
RESWT specifies the maximum wait time from the start of response to the command (NIRQ = L) until slave
transmission request input in I2C communication.
RESWT is determined using the following formula.
Maximum wait time for starting response = T × 2RESWT
T: Typ. 1.88ms(±25%)
RESWT: 0 to 3: (default: 3, typ. approximately 15 ms)
When this field is set to a value other than 0 to 12, a default value will be applied.
Note: T includes an error of ±25%. Set the INTWT and RESWT values in consideration of the error.
IRQSEL
IRQSEL is used for IRQ notification to add the condition of generating an interrupt to the NIRQ pin.
Setting IRQSEL allows an additional interrupt to be generated in addition to a normal host command
processing complete interrupt.
There are two user-selectable additional interrupt sources, RF communication detection or reader/writer
magnetic-field detection. In addition, RF communication detection is selected from FeRAM write completion
by RF command and RF response before sending.
For more information about interrupt source, see Chapter 6 Interrupt Generation Function.
The IRQSEL settings are as follows.

4.2.5 Various Settings
This section describes the parameter settings and operation specifications based on JISX6319-4 for this
RFID.
4.2.5.1 System Code
System code is a parameter specified by the REQ command that is used to identify the RFID. Figure 4-5
shows the system code. The system code is set by the value of the system area SC for FeRAM.
The response operation to the REQ command by system code is shown in Table 4-3.
Figure 4-5 System Code
Table 4-3 Response to REQ Command by System Code
REQ command
System code setting value
RFID's response to REQ command
0xFFFF
Responds regardless of the system area SC setting
0xAAFF
When the value of the upper 1 byte of the SC system area
is 0xAA, the RFID responds regardless of the value of the
lower 1 byte.
Other
Responds only when the setting value of the REQ
command's system code matches the value specified in
the system area SC (and does not respond in other cases).
4.2.5.2 PICC (Proximity IC Card) Identifier
The PICC (Proximity IC Card) identifier is a data used to identify RFID, and is included in the response to the
REQ command. Figure 4-6 illustrates the PICC identifier's format. The PICC identifier (8 bytes) is set in the
system area IDM.
Figure 4-6 PICC Identifier Format
4.2.5.3 Response Time Descriptor
The response time descriptor is used to specify the maximum wait time until the RFID sends a response after
reader/writer sends a command, and is included in the response to the REQ command. Figure 4-7 illustrates

Figure 4-8 shows the response time calculation parameter's format.
Figure 4-8 Response Time Calculation Parameter Format
The response time is calculated by the following formula:
Response time = T × [ (B + 1) × n + (A + 1) ] × 4E
T: 256 × 16/fc (approx. 0.302 ms)
n: No. of blocks or No. of files of command parameter.
4.2.5.4 Anticollision
JISX6319-4 uses the time slot method for anti-collision (prevention of collision). This RFID always responds
according to the first slot.
4.2.5.5 Service
This RFID does not implement the concept of service based on JISX6319-4.
However, it is possible to specify multiple services using a command service list. Table 4-5 shows the
available maximum number of services. When specifying multiple services in the service list, the values of
service list must be set to the same value.

4.2.5.7 Block List
For encrypted communication in tunnel mode, how to specify block list is slightly different from the
JISX6319-4 specification. Figure 4-11 shows the block list referenced from this RFID.
(1) Plaintext (unencrypted) communication in RF communication mode: The block number of block list can be
set freely. The RFID references to all block numbers.
(2) Plaintext (unencrypted) communication in tunnel mode: The block number of block list should be set in
ascending order. The RFID checks that the block number is set in ascending order and if not, it responds with
an error.
(3) Encrypted communication in RF communication mode or tunnel mode: The block number to access is
specified using the block numbers between first and (m-2)th in the block list. The last two block numbers are
dummy. The block number of block list should be set in ascending order. The RFID checks that the block
number is set in ascending order and if not, it responds with an error.
Note: When specifying multiple blocks, communication mode (RF communication mode/ tunnel mode) and
encrypted communication for all blocks should be configured to the same setting; if not, the RFID
responds with an error.
Note: When setting block numbers in ascending order, set to 0x00 following the block number 0xFF (and set
to 0x01 following 0x00). Mode setting (bits 2 to 0 of byte D2) for all blocks should be set to the same
value.

In addition, for encrypted communication, the structure of data is also slightly different from the JISX6319-4
specification. Figure 4-12 shows the block data structure.
(1) Plaintext (unencrypted) communication treats all block data as actual data.
(2) In encrypted communication, of the number of blocks m, the first block data is IV (Initial Vector) to be used
for encryption, data from second to (m-1)th blocks are actual data, and the last block data is MAC value for
Message Authentication Code (MAC).

4.3.8 Various Settings
This section describes the parameter settings and operation specifications based on ISO/IEC14443 TypeB for
this RFID.
4.3.8.1 AFI (Application Family Identifier)
Figure 4-23 shows the format of AFI (Application Family Identifier). The value of AFI is set in the system area
AFI.
AFI is a parameter specified by the REQB command. The response operation to REQB command in this
RFID is shown in Table 4-20. For information about the setting values for AFI, see ISO/IEC14443-3.

REQB command's AFI is matched.
0x0Y
Responds when the value Y of the lower 4 bits of the
REQB command's AFI is matched.
Other
Responds only when the setting value of the REQB
command's AFI matches the value specified in the system
area AFI.
4.3.8.2 PUPI (Pseudo-Unique PICC Identifier)
Figure 4-24 shows the format of PUPI (Pseudo-Unique PICC Identifier). PUPI is an identifier of PICC
(Proximity IC Card). The value of PUPI is set in the lower 4 bytes of the system area IDM.

4.3.8.3 FWI (Frame Waiting Time Integer)
Figure 4-25 shows the format of FWI (Frame Waiting time Integer). FWI is used to specify the maximum wait
time until the PICC sends a response after receiving a command.
Figure 4-25 FWI Format
The maximum wait time is calculated by the following formula:
Maximum wait time = T × 2FWI
T: 256 × 16/fc (fc = 13.56 MHz, approx. 0.302 ms)
FWI: 0 to 14 (integer)
The maximum wait time ranges from approximately 0.302 ms (min.; FWI = 0) to approximately 4949 ms (max;
FWI = 14).
4.3.8.4 File System
This RFID is compliant with the command specification of ISO/IEC7816-4 standards, but does not implement
the file system functionality of the standards. However, in order to ensure the compatibility with
communication to reader/writer, the SELECT command to select files is set to "Normal response" when
specifying the given parameters. For information about how to set the parameters of the SELECT command,
see 4.3.9.4 SELECT.
4.3.8.5 Address
In ISO/IEC14443 TypeB (command is compliant with ISO/IEC7816-4), the addresses of READ and WRITE
commands are specified by bytes P1 and P2 of the command APDU. (See Section 4.3.5 Upper Command
Format)
Figure 4-26 shows the address specification format. Set bit 7 of byte P1 to 0; setting to 1 causes an error.

4.3.8.6 Data
For encrypted communication, the structure of data block for READ and WRITE commands is slightly different
from the ISO/IEC7816-4 command specification. Figure 4-27 shows the data block structure.
(1) Plaintext (unencrypted) communication treats all block data as actual data.
(2) In encrypted communication, the first 16 bytes of data is IV (Initial Vector) used for encryption, following
16×n bytes of data is actual data, and the last 16 bytes is MAC value for Message Authentication Code
(MAC).

5.1 Serial Communication Mode Sequence
This RFID provides a serial communication function via I2C interface.
The host is the master and the RFID operates as the slave.
Figure 5-1 illustrates the sequence in serial communication mode. Each sequence is described below.
SNo.1 (slave reception): The host sends a serial commuinication mode command to the RFID.
SNo.2 (slave transmission): Once the RFID receives the serial communication mode command described in
SNo.1, it processes the command and then sends the result to the host as the response to the
command.
It is also possible to read the status of the RFID by omitting SNo.1 and performing only SNo.2.

5.2.6 Time Chart
Figure 5-3 shows the time chart when I2C is used.
t0: The host inputs a start condition and then inputs a slave address and R/W bit (L). The RFID returns an
ACK if the slave address is identified. Subsequently, if the host inputs a command data, the RFID returns an
ACK in byte units. The host inputs a stop condition last. Pull up the NIRQ pin to high.
t1: The host stops the clock input to the SCK pin after inputting command data. The RFID executes command
processing internally.
t2: Once the internal command processing is completed, the RFID outputs low to the NIRQ pin to send a
response.
t3: The host detects the low output of the NIRQ pin and inputs a start condition, and then inputs a slave
address and R/W bit (H). The RFID returns an ACK and stops the low output of the NIRQ pin if the slave
address is identified. Subsequently, if the host inputs a clock to the SCK pin, the RFID returns an ACK in byte
units. The host inputs an ACK in byte units, and inputs an NACK and stop condition last.

Interrupt Generation Function

Chapter 6 Interrupt Generation Function
90
6.1 Interrupt Source
This RFID provides an NIRQ pin for interrupt output. A low output to the pin enables IRQ notification to notify
the host of generation of an interrupt.
Interrupt sources are described below.
・Serial communication interrupt
An IRQ that is caused by serial communication and issued when processing of the command input from the
host is completed.
Serial communication interrupt cannot be masked.
・RF communication detect interrupt
An IRQ that is caused by RF communication and issued either when RF response before transmission or
when a write to FeRAM with the RF command is completed.
The system area HW2 parameter's IRQSEL selects whether interrupt is generated and the interrupt source.
Bit 2 selects whether interrupt is generated and bit 1 selects the interrupt source.
In addition, even when interrupt generation is enabled, the WREG command for serial command can mask
the IRQ.
・Magnetic-field detect interrupt
An IRQ that is caused by RF magnetic-field detection and issued when an RF magnetic field by
reader/writer is detected.
Bit 0 of the system area HW2 parameter's IRQSEL selects whether interrupt is generated.
In addition, even when interrupt generation is enabled, the WREG command for serial command can mask
the IRQ.
While the contact power supply VDDEX is not applied, an IRQ is issued by starting a power supply due to RF
magnetic field. However, when RF magnetic field disappears, power supply will be stopped and low output of
the NIRQ pin will be stopped.
Any of the IRQs described above are canceled when the slave address is identified by a slave transmission
request from the host, and low output of the NIRQ pin will be stopped.
Note: If Ithe internal voltage VDDD has not reached the reference voltage, an internal reset occurs.
Internal voltage can be generated from the higher voltage either the VDDA and VDDEX.
Therefore, it is possible to set to 1.84V or higher VDDEX at least, generation of the internal reset
will be avoided.

7.1 Tunnel Mode Sequence
This section describes the sequence of tunnel mode, which is shown in Figure 7-1.
SNo.1: Reader/writer sends a tunnel mode command to RFID.
SNo.2: RFID receives the tunnel mode command and issues an interrupt request (IRQ) to the host.
SNo.3: If VDDEX is not applied, the host applies VDDEX.
SNo.4: The host sends a QUERY command (inquiry) to RFID.
SNo.5: RFID sends a response to the QUERY command to the host. The response includes data of the tunnel
mode command in step SNo.1.
SNo.6: The host sends an ANSWER command (notification of the result) to RFID. The command includes
data to be sent to reader/writer.
SNo.7: RFID receives the ANSWER command and sends a response (processing result; Normal end or
Error) to the command to the host.
SNo.8: After sending the response to the ANSWER command in step SNo.7, RFID sends the data of the
ANSWER command to reader/writer as a response to the tunnel mode command.
For more information about tunnel mode operation, see Section 8.2 State Transition Diagram in Operation
Mode, Section 8.3 Flow Chart in Tunnel Mode, or other related sections.

7.2 Communication between Reader/Writer and RFID
This section describes the communication between Reader/Writer and RFID in tunnel mode, based on
JISX6319-4 and ISO/IEC14443 TypeB.
7.2.1 Using JISX6319-4
READ and WRITE commands, same as those of RF communication mode, are used.
Use the given bits of block number to set the tunnel mode commands. For more information, see Section
4.2.5.6 SectionBlock.
For information on how to set block list and block data, see Section 4.2.5.7 Block List.
7.2.2 Using ISO/IEC14443
READ and WRITE commands, same as those of RF communication mode, are used.
Use the given bits of address (P1, P2) to set the tunnel mode commands. For more information, see Section
4.3.8.5 Address.
For information on how to set data, see Section 4.3.8.6 Data.
Chapter 7 Tunnel Mode
94
7.3 Communication between Host and RFID
This section describes the I2C communication between the host and RFID in tunnel mode.
7.3.1.1 Communication Specification
The specification for I2C communication is the same as that for serial communication mode. See Section 5.2
I2C.
QUERY and ANSWER commands are provided only for tunnel mode. For more information about commands,
see Section 7.4 Command.
7.3.1.2 IRQ Notification
Once this RFID receives a tunnel mode command from reader/writer, it sends an IRQ to the host.
IRQ is output from the NIRQ pin. The NIRQ pin also outputs IRQs in other modes than tunnel mode by setting
the system area HW2 parameter's IRQSEL. For more information about IRQSEL, see Section 3.3 ■HW1
(2 bytes) in Section System Area.
When the host receives an IRQ and detects that the supply voltage VDDEX is not applied, it applies VDDEX
and sends a QUERY command to the RFID. The RFID can receive I2C commands at the falling edge of
NIRQ.
In addition, if the RFID does not receive a QUERY command from the host even when the maximum wait time
for QUERY command specified in the system area QWT elapses after the NIRQ pin outputs low, it detects a
timeout. For more information, see Section 8.3 Flow Chart in Tunnel Mode.
95
7.3.2 Response to QUERY Command
When a response to QUERY command in tunnel mode is sent, the RFID reports the content of the command
from reader/writer to the host.
The address setting for response to QUERY is shown in Figure 7-2.
Bit 7 of upper byte is fixed to 0 and bit 6 is fixed to 1. Setting bit 6 to 1 indicates the RFID is in tunnel mode.
Bits 5 and 4 indicate mode.
Table 7-1 shows the meaning of mode of upper byte bits 5 and 4. These bits indicate whether the
communication in tunnel mode is plaintext (unencrypted) or encrypted (private or family key).

7.3.3 Timeout
In tunnel mode command processing for communication between host and RFID, a timeout processing is
applied if the host sends no response to QUERY and ANSWER commands.
Figure 7-3 shows the wait time for commands in tunnel mode.
Subsequent section describes the wait time for QUERY and ANSWER commands.
Figure 7-3 Wait Time for Commands
Note: In timeout measurement processing for I2C, the start of command is detected at the start of ACK
transmission to a slave address input, not start condition.

7.3.3.1 Wait Time for QUERY Command
The time sequence for timeout of waiting for QUERY command (no response from the host) is shown in
Figure 7-4 . The measurement of timeout starts when the IRQ state of NIRQ pin changes to low from high.
A timeout time is QWT setting time.
Figure 7-4 Timeout of Waiting for QUERY Command (No Response from the Host)
Next, the time sequence when the RFID receives a command other than QUERY from the host while it waits
for a QUERY command is shown in Figure 7-5 .Note that the timeout measurement time does not include the
time from serial communication command issue to the response to the command.
For more information, see Section 8.3 Flow Chart in Tunnel Mode.

8.1 Exclusive Control
While in operation mode, this RFID performs an exclusive control not to receive other commands.
Figure 8-1 shows the exclusive control period. The period is from the start of an operation mode command to
the end of the response to the command. In tunnel mode, the period is from the start of the tunnel mode
command from reader/writer (see SNo.1 in Figure 7-1 Tunnel Mode Sequence) to the end of the response to
the command from RFID to reader/writer (see SNo.8 in Figure 7-1 Tunnel Mode Sequence).
Figure 8-1 Exclusive Control Period
Table 8-1 shows the operations in exclusive control period for each operation mode. Illegular cases that are
not generated normally are indicated with parenthesis.
The RFID responds with BUSY to a command from the host if the slave address is identified. It also responds
with BUSY for unimplemented command.
In tunnel mode, the RFID operation differs between before and after IRQ output following the reception of a
tunnel mode command from reader/writer.

Figure 8-2 shows the detail of exclusive control in tunnel mode.
When the RFID receives a command from the host during tunnel mode command reception and before IRQ
output, it sends a response with BUSY and then outputs IRQ.
When the RFID receives a command (other than QUERY) from the host after IRQ output, it responds with
BUSY to the command.

Request for your special attention and precautions
in using the technical information and semiconductors described in this book
(1) If any of the products or technical information described in this book is to be exported or provided to non-residents, the
laws and regulations of the exporting country, especially, those with regard to security export control, must be observed.
(2) The technical information described in this book is intended only to show the main characteristics and application circuit
examples of the products. No license is granted in and to any intellectual property right or other right owned by
Panasonic Corporation or any other company. Therefore, no responsibility is assumed by our company as to the
infringement upon any such right owned by any other company which may arise as a result of the use of technical
information de-scribed in this book.
(3) The products described in this book are intended to be used for general applications (such as office equipment,
communications equipment, measuring instruments and household appliances), or for specific applications as expressly
stated in this book.
Please consult with our sales staff in advance for information on the following applications, moreover please exchange
documents separately on terms of use etc.: Special applications (such as for in-vehicle equipment, airplanes, aerospace,
automotive equipment, traffic signaling equipment, combustion equipment, medical equipment and safety devices) in
which exceptional quality and reliability are required, or if the failure or malfunction of the products may directly
jeopardize life or harm the human body.
Unless exchanging documents on terms of use etc. in advance, it is to be understood that our company shall not be held
responsible for any damage incurred as a result of or in connection with your using the products described in this book
for any special application.
(4) The products and product specifications described in this book are subject to change without notice for modification
and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-
to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements.
(5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating
conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed
the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Other-
wise, we will not be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, take into the consideration of incidence of break down
and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design,
arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages,
for example, by using the products.
(6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors
(ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. We do
not guarantee quality for disassembled products or the product re-mounted after removing from the mounting board.
When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed
time since first opening the packages.
(7) When reselling products described in this book to other companies without our permission and receiving any claim of
request from the resale destination, please understand that customers will bear the burden.
(8) This book may be not reprinted or reproduced whether wholly or partially, without the prior written permission of our
company.
