Identification), which features the following:  Built-in 4-Kbit non-volatile memory with fast write and low power consumption.  RF interface compliant with JISX6319-4 (212 kbps / 424 kbps) and ISO/IEC14443 TypeB (106 kbps / 212 kbps) of the 13.56-MHz contactless IC card standards.  Serial interface compatible with I2C (100 kHz)  Batteryless RF communication  Three communication modes of RF, serial, and tunnel (Tunnel mode allows communications between reader/writer and host CPU via this LSI.)  Encryption communication function that uses AES (128 bits) private-key cryptosystem  Supply voltage range: 1.7 V to 3.6 V 10 Chapter 1 Overview 1.2 Block Diagram Figure 1-1 shows a block diagram. This RFID provides RF interface for contactless communication with external reader/writer, serial interface for contact communication with external host, control logic for command processing and various controls, 2-Kbit transmit/receive buffer for RF communication, 4-Kbit non-volatile memory, and AES cryptosystem. Figure 1-1 Block Diagram 11 Chapter 1 Overview 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 non-volatile memory 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 non-volatile memory 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 in Operation Mode. State Transition Diagram RF communication mode R/W RFID Master Slave Host Serial communication mode R/W RFID Host Slave Master RFID Host Tunnel mode R/W Master Slave Figure 1-2 12 Operation Mode Chapter 1 Overview 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. RF communication mode Encrypted (or plaintext) communication R/W RFID Master Slave Serial communication mode R/W Host Plaintext (unencrypted) communication RFID Host Slave Master Tunnel mode Encrypted (or plaintext) communication Plaintext (unencrypted) communication R/W RFID Master Host Slave Figure 1-3 Encrypted Communication Function 13 Chapter 2 Pin Descriptions 2 Chapter 2 Pin Descriptions 2.1 List of Pins Table 2-1 shows a list of pins of this RFID and Figure 2-1 illustrates the pin assignments of this RFID. Table 2-1 List of Pins Pin No. Name I/O Output type 1 N.C. - - 2 VDDEX - Power 3 SDA I/O 4 VSS - 5 NIRQ Output 6 SCL Input Description Non connection Contact power supply (Apply 1.7 V through 3.6 V.) Open Drain Host interface (I2C: 100 kHz) GND Ground Open Drain Interrupt request output - Host interface (I2C: 100 kHz) Connector : BL509N series (TAIWAN SUNCAGEY INDUSTRIAL CO., Ltd.) Figure 2-1 Pin Assignments 16 Chapter 2 Pin Descriptions Figure 2-2 Outside drawing 17 Chapter 2 Pin Descriptions 2.2 Pin Descriptions ■ Ground (VSS) A reference power supply pin. Connect to the ground of the host CPU. ■ 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. . ■ 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. 18 Chapter 2 Pin Descriptions 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.

For more information about this parameter, see Section 7.3.3 Timeout. Table 3-10 describes the TNPRM parameter. Table 3-10 TNPRM Parameter Address Bit 7 Bit 6 0x01FC  Bit 5 Bit 4 Bit 3 Bit 2 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 × 2 QWT 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 × 2 AWT 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) HW2 is an area to store various setting data related to the hardware of this RFID. Table 3-11 describes the HW2 parameter. INTWT and RESWT are parameters related to timeout in I2C communication. For the setting of IRQSEL for IRQ notification, see Table 3-12.

INTWT is determined using the following formula. Maximum wait time between characters = T × 2 INTWT 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 × 2 RESWT 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 Non-volatile memory 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. Table 3-12 IRQSEL Setting for IRQ Notification Bit 2 Bit 1 Bit 0 Meaning 0 0 X Do not generate an interrupt when RF response before transmission or when a write to Non-volatile memory with the RF command is completed. 0 1 X Reserved 1 0 X Generate an interrupt when RF response before transmission. 1 1 X Generate an interrupt when a write to Non-volatile memory with the RF command is completed. X X 0 Do not generate an interrupt when a magnetic field is detected. X X 1 Generate an interrupt when a magnetic field is detected. By default, value of each bit of IRQSEL is 0. 28 Chapter 3 ■ Memory Map SC (2 bytes) SC is used as the JISX6319-4 system code (2 bytes).

Figure 4-5 shows the system code. The system code is set by the value of the system area SC for Non-volatile memory. The response operation to the REQ command by system code is shown in Table 4-3. System code D0 D1 SC 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. PICC identifier D0 D1 D2 D3 D4 D5 D6 D7 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 37 Chapter 4 RF Communication Mode the response time descriptor's format. In hardware, D0, D1, and D7 bytes are set to FFh and D2 to D4 bytes are set to 00h. The response time calculation parameters D5 and D6 bytes are the values of the system area. Table 4-4 shows the response time calculation parameter and corresponding command.

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. 38 Chapter 4 RF Communication Mode Table 4-5 Maximum Number of Services Command Maximum No. of services READ 15 WRITE 11 Note: The RFID responds with an error when multiple services are not set to the same service file value. 4.2.5.6 Block JISX6319-4 uses data of 16-byte blocks. Block number is used to specify each block. Figure 4-9 shows the block element of 2 bytes and Figure 4-10 shows the block element of 3 bytes. All of bits 6 to 4 of byte D0 for access mode setting should be set to 0 in this RFID; otherwise the RFID responds with an error.

Table 4-6 shows the mode settings for tunnel mode and encrypted communication. Bits 2 to 0 of byte D2 in 3-byte block element format are used. All of bits 7 to 3 of byte D2 should be set to 0; otherwise the RFID responds with an error. Table 4-6 Mode Settings Byte D2 of block No. Block element format 2 bytes 3 bytes Meaning Communication mode Bit 2 Bit 1 Bit 0 Encrypted communication - - - 0 0 0 0 1 0 0 1 1 0 0 1 Reserved (Setting this field causes an error.) 1 0 0 Plaintext (unencrypted) communication 1 1 0 1 1 1 1 0 1 Plaintext (unencrypted) communication RF communication mode Encrypted communication (private key) Encrypted communication (family key) Tunnel mode Encrypted communication (private key) Encrypted communication (family key) Reserved (Setting this field causes an error.) Table 4-7 shows the available maximum number of blocks. For READ command, the number is 15 for plaintext (unencrypted) communication in RF communication mode. The maximum number of blocks for WRITE command depends on the number of services.

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.

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).

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. AFI D0 AFI Figure 4-23 AFI Format Table 4-20 REQB Command Response Operation REQB command RFID's response to REQB command AFI setting value 0x00 Responds regardless of the system area AFI setting. 0xY0 Responds when the value Y of the upper 4 bits of the 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. PUPI D0 D1 D2 D3 Lower 4 bytes of IDM Figure 4-24 PUPI Format 59 Chapter 4 RF Communication Mode 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 × 2 T: FWI 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.

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).

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.

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. t0 NIRQ t1 t2 t3 IRQ generated by RFID (Command processing terminated) SCL SDA Address command Address Response Figure 5-3 Time Chart 87 Chapter 6 Interrupt Generation Function 6 Chapter 6 Interrupt Generation Function 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 Non-volatile memory 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. 90 Chapter 7 Tunnel Mode 7 Chapter 7 Tunnel Mode 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.

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. 93 Chapter 7 Tunnel Mode 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. 94 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).

Figure 7-3 shows the wait time for commands in tunnel mode. Subsequent section describes the wait time for QUERY and ANSWER 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). Command Response Time Exclusive control period 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. Table 8-1 Operation during Exclusive Control (Irregular Case in Parenthesis) Current operation mode RF communication mode Serial communication mode Tunnel mode 110 Receive command Operation to a receive command Operation mode From (RF communication mode) (R/W) (No response) Serial communication mode Host Responds with BUSY. (Tunnel mode) (R/W) (No response) Tunnel mode (Host) (Responds with BUSY.)

(Tunnel mode) (R/W) (No response) Tunnel mode Host See 7.1 Tunnel Mode Sequence. Chapter 8 Annex 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. ● Issuing a serial interface command before generating IRQ Exclusive control period I2C (RFID side) RF I/F Slave reception Command Response Command Response with BUSY Slave transmission NIRQ IRQ generated ● Issuing a serial interface command after generating IRQ Exclusive control period I2C (RFID side) RF I/F Command Response Command other than QUERY Slave reception Response with BUSY Slave transmission NIRQ IRQ generated Figure 8-2 Exclusive Control in Tunnel Mode 111 Chapter 8 Annex 8.2 State Transition Diagram in Operation Mode Figure 8-3 shows the state transition diagram of this RFID in operation mode.
