It is able to access FRAM User memory through the SPI interface. In this case, the external power supply is required. 1. Pin Function Description The Serial Pin and its function descriptions are shown in the table below. • Pin function Pin Number Pin Name Function Description 19 BUSY RF Interface Status When the VDD pin is set to ON during RF communication, BUSY will output “H”. In this status, serial communication will be ignored even if RF and serial communications are both being performed at the same time, because the chip can only perform RF communication when BUSY outputs “H”. Switching to the serial communication can be performed only when BUSY is “L”. 20 SPI SPI Mode Switch pin This is an input pin to control to switch to Serial communication mode. When SPI is “H”, the LSI can be transferred to Serial communication mode. 24 XCS Chip Select pin This is an input pin to select chip. When XCS is “H”, device is deselect (standby status) as long as the LSI is not write status internally. And SO becomes High-Z. In this case, inputs from all pins other than the antenna pin are ignored. When XCS is " L" , the chip will be in selected state (active). XCS must fall before inputting opcode. 23 SCK Serial Clock pin This is a clock input pin to input/output serial data. SI is loaded synchronously to a rising edge. SO is output synchronously to a falling edge. 22 SI Serial Data Input pin This is an input pin of serial data. It inputs op-code, address, and writing data. 21 SO Serial Data Output pin This is an output pin of serial data. Reading data of FRAM memory are output. It is High-Z during standby. 4 VDD Supply Voltage pin: 3.3 V 3 VSS Ground pin DS411-00004-0v03-E 3 MB89R112 2. Connection to SPI Interface This LSI works as a slave of SPI. It can be connected to the microcontroller equipped with SPI port as shown in the figure below. The external SPI controller shall monitor the BUSY signal. When a BUSY signal is “H”, the controller shall wait until “L” before performing SPI communication. When a BUSY signal is “H” and serial communication is performed, the serial communication shall be ignored.

Arbitration between RF and SPI communication This LSI has an access arbitration feature when there is access from both RF I/F and SPI I/F simultaneously. In this case, RF communication has priority. BUSY signal indicates that there is access from RF I/F, and it is validated when VDD is connected. The controller needs to confirm the BUSY signal before changing to the SPI communication mode. When the BUSY signal is in “H”, the SPI communication is ignored if the SPI communication is performed at the same time because the LSI is executing RF communication. The BUSY pin outputs “H” if the VDD pin is turned on during RF communication as the figure shown below. • Arbitration between RF and SPI communication Valid port RF SPI SPI RF SPI Internal rectification power supply VDD BUSY SPI XCS SI/SCK set to “L” High-Z High-Z High-Z set to “L” High-Z High-Z SO DS411-00004-0v03-E 5 MB89R112 5. Power Sequence in Serial Communication Mode The power sequence in Serial communication mode is shown in the figure below. After asserting VDD, check that BUSY is “L” and then assert SPI and XCS at the same time. Wait for 1 ms or more after asserting XCS and then release XCS and begin serial communication. The timing specifications for the power sequence are shown in the following table. Refer to “■ COMMANDS OF SERIAL COMMUNICATION MODE” for details on the serial communication timing specifications. • Serial communication power sequence RF communication Serial communication Internal voltage BUSY tSU tPH VDD set to “L” SPI tPU tPD set to “L” XCS set to “L” SCK/SI/SO (Refer to “■ COMMANDS OF SERIAL COMMUNICATION MODE” for details) • Timing specifications during serial communication Parameter Symbol Value (Min) Unit SPI rising start time tSU 1000 μs Power supply hold time tPH 0 μs XCS level hold time at power ON tPU 1000 μs XCS level hold time at power OFF tPD 0.06 μs 6 DS411-00004-0v03-E MB89R112 6.

The system area contains UID, AFI, DSFID, and security status (can write or cannot write) data for individual block. UID is fixed and cannot be updated. AFI and DSFID are written at the factory, and can be updated and locked (disable to write) with commands. DS411-00004-0v03-E 9 MB89R112 2. MB89R112 memory access note This product has different memory access methods between via RF and via SPI interface, furthermore FRAM memory data handling is different as follows. Therefore, the data storage within one block should be dealt carefully when user accesses to user area via RF and SPI. • Data handling via RF memory access One block 32-bytes is unit used for data Reading/Writing via RF, and data should be LSB first within one block. • Data handling via SPI memory access 2-bytes is unit used for data Reading/Writing via SPI, and data should be MSB first within one block. Therefore data handling via SPI memory access is reversal compared to the one via RF memory access. • Example of Data allocation When 32 bytes data write in block0 from RF DATA = 0001_0203_0405_0607_0809_0A0B_0C0D_0E0F_1011_1213_1415_1617_1819_1A1B_1C1D_1E1F H Data order on RF Air DATA = 1FH→1EH→1DH→1CH→1BH ······ 04H→03H→02H→01H→00H RF 1block (32byte) data allocation Block Number Logical address (RF) (1addres = 16bit) RF LSB First 00H SPI MSB First Data 15 0 0000H 1E1FH 0001H 1C1DH 0002H 1A1BH 0003H 1819H 0004H 1617H 0005H 1415H 0006H 1213H 0007H 1011H 0008H 0E0FH 0009H 0C0DH 000AH 0A0BH 000BH 0809H 000CH 0607H 000DH 0405H 000EH 0203H 000FH 0001H When 32bytes data continuously read from bock0 via SPI DATA = 1E1F_1C1D_1A1B_1819_1617_1415_1213_1011_0F0E_0C0D_0A0B_0809_0607_0405_0203_0001 H 10 DS411-00004-0v03-E MB89R112 ■ DATA ELEMENT DEFINITION 1. Unique Identifier (UID) The MB89R112 has a 64-bit unique identifier (UID) that complies with ISO/IEC 15693-3. The UID is used to distinguish a transponder from another transponder in the anti-collision algorithm described later. The UID consists of the 3 items shown in the following. • An 8-bit data whose value is always “E0H” (bit 57 to bit 64) • An 8-bit IC manufacturer code whose value is always “08H”, and is defined by ISO/IEC 7816-6/AMI (bit 49 to bit 56) • Unique 48-bit serial number assigned by FUJITSU SEMICONDUCTOR (bit 1 to bit 48) Among the unique 48-bit serial number assigned by FUJITSU SEMICONDUCTOR, the 1 byte from bit 41 to bit 48 defines MB89R112 code whose value is “05H”. And the 5 bytes from bit 1 to bit 40 define other serial number. • Structure of UID MSB LSB 64 57 56 “E0H” 49 48 IC manufacturer code “08H” DS411-00004-0v03-E 41 40 “05H” 1 other serial number Unique serial number assigned by FUJITSU SEMICONDUCTOR 11 MB89R112 2. Application Family Identifier (AFI) The application family identifier (AFI) identifies the type of application set by the transponder. The AFI can be written with a command. The AFI is 8-bit data and is stored in the system area of FRAM. The factory default setting of the AFI is “00H”. • Types of AFI Application Application Sub-Family Family (bit 8 to bit 5) (bit 4 to bit 1) Application Use Field Example/Note “0” “0” All families and sub-families No applicative preselection X “0” All sub-families of family X X Y Only the Yth sub-families of family X ⎯ “0” Y All families of Yth sub-families ⎯ “1” “0”, Y Transport Mass transit, bus, airline “2” “0”, Y Financial IEP, banking, retail “3” “0”, Y Identification “4” “0”, Y Telecommunication “5” “0”, Y Medical “6” “0”, Y Multimedia “7” “0”, Y Gaming “8” “0”, Y Data storage “9” “0”, Y EAN-UCC system for application identifiers Managed by ISO/IEC JTC 1/SC 31 “A” “0”, Y ISO/IEC JTC 1/SC 31 Data identifiers as defined in ISO/IEC 15418 “B” “0”, Y UPU Managed by ISO/IEC JTC 1/SC31 “C” “0”, Y IATA Managed by ISO/IEC JTC 1 “D” “0”, Y “E” “0”, Y “F” “0”, Y Wide applicative preselection Access control Public telephone, GSM ⎯ Internet services ⎯ Portable files Managed by ISO/IEC JTC 1/SC 17 RFU* Managed by ISO/IEC JTC 1/SC 17 Managed by ISO/IEC JTC 1/SC 17 * : Reserved for future use Note : Both X value and Y value are “1” to “F”. In the status of the AFI_flag setting; • If the AFI is not supported by the transponder, no response to all requests is returned. • If the AFI is supported by the transponder, the response is returned only if the value is in accord with the AFI sent from a reader/writer. 3. Data Storage Format Identifier (DSFID) The data storage format identifier (DSFID) indicates how data is structured in the transponder (LSI memory device). The DSFID can be programmed with a command. The DSFID is 8-bit data and is stored in the system area of FRAM. The factory default setting of the DSFID is “00H”. 12 DS411-00004-0v03-E MB89R112 4. Cyclic Redundancy Check (CRC) When a frame is received, reception of correct data making up the frame is assumed only when the value of the cyclic redundancy check (CRC) code is valid. For error-checking purposes, a 2-byte CRC code value is inserted between data and the EOF signal. The value of CRC code is required from all the data contained between the SOF and CRC field in each frame. Method of calculation is provided in ISO/IEC 13239. The details are provided in ISO/IEC 15693-3 and ISO/IEC 18000-3 (Mode 1) . The initial value of the CRC code provided in ISO/IEC 15693-3 is “FFFFH”. The CRC code is transferred, beginning with the lowest-order bit in the lowest-order byte. • CRC bit/byte transition order LSByte LSBit MSByte MSBit CRC 16 (8 Bits) LSBit MSBit CRC 16 (8 Bits) First transmitted bit of the CRC DS411-00004-0v03-E 13 MB89R112 ■ FUNCTION DESCRIPTION 1. Communication from Reader/Writer to Transponder (1) Modulation method The MB89R112 supports both 10% ASK modulation and 100% ASK modulation. Modulation index m is defined as m = (a - b)/(a + b) with reference to the modulated waveform shown below. The values a and b indicate, respectively, the maximum and minimum amplitude of magnetic field transmitted from a reader/writer. • Modulation of the carrier for 10% ASK hr y y hf t2 t1 a t3 b 0V 13.56 MHz • Modulation of the carrier for 100% ASK t3 t1 t4 105 % 95 % 60 % a 5% 0V t2 b 13.56 MHz Maximum and minimum values of t1, t2, t3 and t4 are shown in the table of “ ■RECOMMENDED OPERATING CONDITIONS”. In this table, y is 0.05 (a-b) and the maximum value of hf and hr is 0.1(a-b). 14 DS411-00004-0v03-E MB89R112 (2) Data rate and data coding The MB89R112 supports only 1 out of 4 mode for bit coding, not 1 out of 256 mode. In 1 out of 4 mode, 2bit signals are coded in a period of 75.52 μs as shown in the following. When coding takes place, the data rate is 26.48 kbps (fc/512). Each signal is transmitted beginning with the lowest bit. • Coding Method in 1 out of 4 Mode • “00B” pulse position 9.44 μs 9.44 μs 75.52 μs • “01B” pulse position (1 = LSB) 28.32 μs 9.44 μs 75.52 μs • “10B” pulse position (0 = LSB) 47.20 μs 9.44 μs 75.52 μs • “11B” pulse position 66.08 μs 9.44 μs 75.52 μs (3) Data frame A data frame begins with a start of frame (SOF) signal and ends with an end of frame (EOF) signal. The MB89R112 is enabled to receive a frame from a reader/writer within 300 μs after the MB89R112 has sent a frame to the reader/writer. The MB89R112 is also enabled to receive a frame from a reader/writer within 1 ms after power has been supplied to the MB89R112. • Waveforms of SOF and EOF signals of a frame sent from a reader/writer SOF 9.44 μs 9.44 μs 37.76 μs 9.44 μs 37.76 μs EOF 37.76 μs DS411-00004-0v03-E 9.44 μs 9.44 μs 15 MB89R112 2. Communication from Transponder to Reader/Writer • Minimum load modulation amplitude (Vlm) : 10 mV (based on ISO/IEC 10373-7) • Load modulation subcarrier frequency (fs) : 423.75 kHz(fc/32) The MB89R112 supports only 1-subcarrier system. (Not the 2-subcarrier system.) • Data rate : The MB89R112 supports the following 2 data rate modes : • Low data rate • High data rate One of the 2 data rate modes is specified by the Data_rate_flag (described later) sent from the reader/writer. In low data rate mode, the data rate is 6.62 kbps (fc/2048); in high data rate mode, it is 26.48 kbps (fc/512). When receiving the Fast commands (Custom commands) , the communication starts from the transponder with the data rate that is twice as fast as normal data rate. In this case, the 2 data rate modes of low data rate and high data rate specified by the Data_rate_flag is supported. In Low data rate mode, the data rate is 13.24 kbps (fc/1024) ; in high data rate mode, it is 52.97 kbps (fc/256) . (1) Bit coding The Manchester coding is used for the bit coding. The following figures show the signals modulated in high data rate mode when ISO command is received and the same signals when fast command is received. In low data rate mode of both ISO commands and fast commands, the number of pulses for subcarrier and data transfer time are 4 times as large as the number in high data rate mode. • Signal waveforms by load modulation in high data rate mode (ISO commands) • Logic 0 423.75 kHz subcarrier 18.88 μs (modulated) 18.88 μs (not modulated) 37.76 μs • Logic 1 423.75 kHz subcarrier 18.88 μs (not modulated) 18.88 μs (modulated) 37.76 μs • Signal waveforms by load modulation in high data rate response mode (fast commands) • Logic 0 9.44 μs 9.44 μs 18.88 μs • Logic 1 9.44 μs 9.44 μs 18.88 μs 16 DS411-00004-0v03-E MB89R112 (2) Data frame A data frame sent from a transponder starts with a start of frame (SOF) signal and ends with an end of frame (EOF) signal. The following figures show the SOF and EOF signals sent in high data rate mode when an ISO command is received and the same signals when a fast command is received. In low data rate mode of both ISO commands and fast commands, the number of pulses in subcarrier and data transfer time are 4 times as large as the number in high data rate mode. The reader/writer shall be ready to receive a frame from the transponder within 300 μs after having sent a frame to the transponder. • Waveforms of SOF and EOF signals of a frame sent from a transponder (ISO commands) • SOF 423.75 kHz subcarrier 56.64 μs 56.64 μs 37.76 μs • EOF 37.76 μs 56.64 μs 56.64 μs • Waveforms of SOF and EOF signals of a frame sent from a transponder (fast commands) • SOF 423.75 kHz Subcarrier 28.32 μs 28.32 μs 18.88 μs • EOF 423.75 kHz Subcarrier 18.88 μs 28.32 μs 28.32 μs 3. FRAM Data Protection if Power Lost During Data Writing MB89R112 accesses to FRAM with the unit of 2 bytes. When RF power is shut down during accessing FRAM, writing in FRAM is completed by the charges stored in a smoothing capacitor on the LSI and FRAM data writing error is prevented. Therefore, the commands of 1 byte access such as Write AFI, Write DSFID and Lock command are protected from the power down. On the other hand, the commands of more than 2 bytes access such as Write Single Block command may not protect all the data from the power down during the access. In this case, it is recommended to confirm the data correctness by a read command. DS411-00004-0v03-E 17 MB89R112 4. Requests/Responses A request is sent from the reader/writer to the transponder. In replying to the request, the transponder sends a response to the reader/writer. Each request, and response, is transmitted in each single frame. • Structure of requests and responses A request consists of the following 5 fields : • Flag • Command code • Parameter (required or optional depending on the command) • Application data • CRC A response consists of the following 4 fields : • Flag • Parameter (required or optional depending on the command) • Application data • CRC Each byte is transferred, beginning with the lowest bit. When two or more bytes are transferred, transfer begins with the lowest one. 5. Operating Modes The MB89R112 has the following 3 operating modes : Each mode specifies a different mechanism for how the transponder returns a response in replying to a request from the reader/writer : • Addressed mode The MB89R112 enters Addressed mode when the Address_flag is set to “1”. In Addressed mode, a request includes a UID (the Address_flag is set to “1” simultaneously), and only the transponder that matches the UID in the request returns a response. If no transponder that matches the UID exists, a response is not returned. • Non-Addressed mode The MB89R112 enters Non-Addressed mode when the Address_flag is set to “0”. In Non-Addressed mode, a request does not include a UID. The transponders that receive the request execute processing and return its response in accordance with the requested command. • Select mode The MB89R112 enters Select mode when the Select_flag is set to “1”, and the Address_flag is set to “0”.

The Anti-collision algorithm is designed to examine the transponders located within reader/writer communication areas on the basis of UID. The reader/writer issues an Inventory command to transponders, and some transponders return responses while other transponders do not respond, according to the algorithm described in “10. Execution of Inventory Command by a Transponder”. 9. Request Parameter • Request Parameter Settings Set the reader/writer as follows before issuing the Inventory command. • The Nb_slots_flag (bit 6), which is a request flag, is set to the desired value : “0” : 16 slots (for plural transponders) “1” : 1 slot (for single transponder) • A mask length and a mask value are added after the command code. • The mask length represents the data length of the mask value in bits. • The mask value is integer bytes of data, transmitted beginning with the lowest bit. If the mask data is not a multiple of 8 (bits) in length, 0 is padded on the MSB side of the mask value so that the data is in units of bytes. The following figure shows an example of the mask value with padding. Since the mask length is 12 bits, the mask value is padded with 4 bits on the MSB side so that the mask data is in units of bytes (2 bytes = 16 bits in this case). If the AFI flag in the request flags is set in the format explained in “• Structure of the request frame of 6. Request Format”, an AFI field is added to the format. The command ends with transmission of an EOF signal as described in “1. Communication from Reader/Writer to Transponder”. Thereafter, processing in the first slot starts immediately. To proceed to the next slot, the reader/writer sends an EOF signal. • Format of the Command SOF Flag Command code Optional AFI Mask length 8 bits 8 bits 8 bits Mask value CRC 0 to 64 bits 16 bits 8 bits EOF • Example of the Mask Value with Padding LSB MSB DS411-00004-0v03-E 0000 0100 1100 1111 Pad Mask value 21 MB89R112 10. Execution of Inventory Command by a Transponder A transponder returns a response to the reader/writer when its UID is equal to the value that consists of the mask value and the number of slots. The mask value is sent in the Inventory command, and the number of slots is determined by the number of times the EOF signal is transmitted. • Algorithm for execution of processing by a transponder The following figure shows the algorithm for the execution of processing by a transponder when an Inventory command is received. The next figure shows the relationship between the UID and the mask value. • Algorithm for Execution of Processing by a Transponder when Inventory Command NbS SN LSB (value, n) & Slot_Frame : Total number of slots (1 or 16) : Current slot number : The “n” least significant bits of value : Concatenation operator : SOF or EOF SN = 0 Nb_slots_flag=1?

The mask value is padded with “0” into the higher bit side so to make the byte-unit length (a multiple of 8 bits). 000••• Mask value (specified by the Inventory command) Mask length If Inventory command is received, the slot counter is reset to “0”. Slot counter If EOF is received, the increment of the slot counter is started by the transponder.

If the value is in accord with the mask value, the response is returned by the transponder.

Anti-Collision Sequence • Execution of anti-collision sequence The following steps summarize the main cases that can occur during a typical anti-collision sequence where the number of slots is 16. 1) The reader/writer sends an Inventory command. The Nb_slots_flag bit of the request flags is set to “0” to specify the number of slots. 2) In slot 0, transponder 1 transmits its response in the time t1_a from the detection of the rising edge of the EOF. In this case no collision occurs and the UID of transponder is received and registered by the reader/ writer. 3) The reader/writer sends an EOF signal to switch to the next slot in the time t2_a after the response 1. 4) In slot 1, transponder 2 and transponder 3 transmit their response in the time t1_a from the detection of the rising edge of the EOF. In this case, the reader/writer cannot recognize the UIDs of the two transponders because the collision occurs, and the reader/writer remembers that a collision was detected in slot 1. 5) The reader/writer sends an EOF signal to switch to the next slot in the time t2_a after the responses. 6) In slot 2, no transponder transmits a response. The reader/writer does not detect any response, and sends an EOF signal to switch to the next slot in the time t3_a from the detection of the rising edge of the EOF. 7) In slot 3, transponder 4 and transponder 5 transmit their response in the time t1_a from the detection of the rising edge of the EOF, and another collision occurs. 8) The reader/writer sends a request (for example, a Read Single Block command, described later) to the transponder 1, which UID was already correctly received. 9) All transponders detect an SOF signal and exit the Anti-collision sequence. In this case, since the request is addressed to transponder 1 (Addressed mode), only transponder 1 transmits its response. 10) All transponders are ready to receive another request from the reader/writer. If the Inventory command is sent again, the Anti-collision sequence starts from slot 0. Note : t1_a, t2_a, t3_a are specified in “12.

Timing definitions (1) Period during which the MB89R112 waits for the start of response transmission after an EOF signal transmitted from the reader/writer : t1_a After detection of an EOF signal sent from the reader/writer, MB89R112 must wait for a certain time (t1_a) before sending a response to the reader/writer. t1_a begins at the rising edge of the EOF pulse, and it is defined as follows. The minimum value is 4320/fc (318.6 μs), the nominal value is 4352/fc (320.9 μs), and the maximum value is 4384/fc (323.3 μs). Even if the 10% ASK modulated signal from the reader/writer is detected within the time t1_a, the transponder ignore the signal and wait for further time t1_a before starting to transmit. (2) Period during which the MB89R112 ignores modulated signals after an EOF signal transmitted from the reader/writer : tmit After detection of an EOF signal sent from the reader/writer, MB89R112 must ignore the 10% ASK modulated signals from the reader/writer for a time (tmit). tmit begins at the rising edge of the EOF pulse. The minimum value of tmit is defined as 4384/fc (323.3 μs) + tnrt. In the above expression, tnrt stands for the response time of MB89R112. (3) Period during which the reader/writer waits before sending a request : t2_a When the reader/writer has received a response from the transponder to a previous request other than Inventory and Stay Quiet command, it shall wait a time t2_a before sending a subsequent request. The minimum value of t2_a is 309.2 μs. It is defined in ISO/IEC 15693-3. And ISO/IEC 18000-3 (Mode 1) . (4) Period during which the reader/writer waits before sending a request during execution of the Inventory command : t2inv While an Inventory command is being executed, the reader/writer sends an EOF signal when it shifts to the next slot. In this case, the wait time is defined as follows depending on whether transponders return responses : - Wait time applied when the reader/writer has received one or more responses : t2invwr It is defined in ISO/IEC 15693-3. And ISO/IEC 18000-3 (Mode 1) that when the reader/writer has received one or more responses, the reader/writer must wait until responses from the transponders have been completed (that is, the reader/writer receives an EOF signal or tnrt passes). After that, the reader/writer must wait until t2_a passes before sending an EOF signal to switch to the next slot. - Wait time applied when the reader/writer has not received any responses : t3_a When the reader/writer has not received any responses from the MB89R112, the reader/writer must wait until t3_a passes before sending an EOF signal. In this case, t3_a begins at the rising edge of the EOF pulse that was sent previously. The minimum value of t3_a is defined as shown in the following table. MB89R112 does not support the minimum value of t3_a as “4384/fc (323.3 μs) + tsof” when the reader/ writer sends a 100% modulated EOF, which is defined in ISO/IEC 15693-3 and ISO/IEC 18000-3 (Mode 1). (a) If the reader/writer sends a ASK10% modulated EOF, the minimum value of t3_a (ASK10%) is “4384/ fc (323.3 μs + tnrt') (b) If the reader/writer sends a ASK100% modulated EOF, the minimum value of t3_a (ASK100%) is “4384/fc (323.3 μs + tsof') tnrt: The nominal response time of transponder tsof: The time for transponder to transmit a SOF to the reader/writer 26 DS411-00004-0v03-E MB89R112 • t3_a for ASK10% and ASK100% signal Reader/Writer SOF Inventory command New command (or EOF signal) EOF No response MB89R112 t1_a t3_a (ASK100 %) t3_a (ASK10 %) Timing tsof tnrt Possible to receive ASK 10 % signal Ignore ASK 10 % signal MB89R112 ASK signal handling Reset t1_a after receiving ASK 100 % signal Ignore ASK 100 % signal Possible to receive ASK 100 % signal • Timing specification Min Typ Max t1_a 4320/fc (318.6 μs) 4352/fc (320.9 μs) 4384/fc (323.3 μs) tmit 4384/fc (323.3 μs) + tnrt ⎯ ⎯ t2_a 4192/fc (309.2 μs) ⎯ ⎯ t2invwr t2_a + tnrt ⎯ ⎯ t3_a (ASK10%) 4384/fc (323.3 μs) + tnrt ⎯ ⎯ t3_a (ASK100%) 4384/fc (323.3 μs) + tsof ⎯ ⎯ tnrt tsof DS411-00004-0v03-E ⎯ Low data rate High data rate Fast Low data rate Fast High data rate : : : : 15708.16 3927.04 7854.08 1963.52 ms ms ms ms ⎯ ⎯ Low data rate High data rate Fast Low data rate Fast High data rate : : : : 604.16 151.04 302.08 75.52 ms ms ms ms ⎯ 27 MB89R112 ■ COMMANDS OF RF COMMUNICATION MODE The following Mandatory and Optional commands defined by ISO/IEC 15693-3 are supported.

Stay Quiet command On receiving the Stay Quiet command, the transponder enters the quiet state. The transponder does not return any responses, including an error indication. In the quiet state, the transponder does not execute any request for which the Inventory_flag (bit 3) is set to “1” and executes only a command for which the Address_flag (bit 6) is set to “1”. The transponder exits the quiet state only in the following cases: • The transponder enters the power-off state. • The transponder receives the Select command and enters the select state. • The transponder receives the Reset to Ready command and enters the ready state. • Request [Request from the reader/writer to the transponder] Command SOF Flag (Stay Quiet) 8 bits 8 bits (“02H”) UID (necessary) CRC 64 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] No response DS411-00004-0v03-E 29 MB89R112 2.

If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the Option_flag (bit 7) is “0”, the transponder returns only the data in the specified block to the reader/writer. • Request [Request from the reader/writer to the transponder] Command UID SOF Flag (Read Single Block) (Addressed mode) 8 bits (“20H”) 8 bits Number of blocks CRC 8 bits 16 bits 64 bits EOF • Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits (2) When Error_flag not set SOF Flag EOF Block security status (option) Data CRC 8 bits 256 bits 16 bits 8 bits (“00H”) EOF 2-2. Write Single Block command On receiving the Write Single Block command, the transponder writes the single block data included in the request to the specified block. The transponder performs verification after writing and returns an error code if the writing has failed. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation starting after “t1nom (320.9 μs) + a multiple of 4096/fc (302.1 μs)” with total tolerance of ± 32/fc (2.4 μs) and latest within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/ writer and upon such reception still return its response (However, if an EOF is not sent within 38 ms, the time-out occurs and the transponder can receive another command). • Request [Request from the reader/writer to the transponder] Command UID SOF Flag (Write Single Block) (Addressed mode) 8 bits 30 8 bits (“21H”) 64 bits Number of blocks Data CRC 8 bits 256 bits 16 bits EOF DS411-00004-0v03-E MB89R112 • Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits (2) When Error_flag not set SOF Flag CRC 8 bits (“00H”) 16 bits EOF EOF 2-3. Lock Block command On receiving the Lock Block command, the transponder locks (write disable) permanently the data stored in one specified single block. The transponder performs verification after writing and returns an error code if the writing has failed. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the lock operation starting after “t1nom (320.9 μs) + a multiple of 4096/fc (302.1 μs)” with total tolerance of ± 32/fc (2.4 μs) and latest within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/ writer and upon such reception still return its response.

Read Multiple Blocks Command On receiving the Read Multiple Blocks command, the transponder reads the data stored in the specified successive blocks to the reader/writer. If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the Option_flag (bit 7) is “0”, the transponder returns only the data in the specified blocks to the reader/writer. The value of the “number of blocks” field specified in the request is the expected number of blocks minus 1. Setting the number of blocks to “01H” makes a request to read 2 blocks. Setting the number of blocks to “00H” makes a request to read 1 block (the request having the same effect as the Read Single Block command). • Request [Request from the reader/writer to the transponder] Command UID SOF Flag (Read Multiple Blocks) (Addressed mode) 8 bits 8 bits (“23H”) First block number Number of blocks CRC 8 bits 8 bits 16 bits 64 bits EOF • Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF (2) When Error_flag not set SOF Flag 8 bits (“00H”) Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits Block security status (option) Data CRC 8 bits 256 bits 16 bits EOF EOF Repeated as required 32 DS411-00004-0v03-E MB89R112 2-5.

Fast Read Multiple Blocks Command The Fast Read Multiple Blocks command is the same as the Read Multiple Blocks command that reads the data of the specified successive blocks. Up to 256 blocks of data can be read for one request. The data rate in the response is twice as defined in ISO/IEC 15693. If the Option_flag (bit 7) is “1”, the transponder adds block security status information in the response. If the Option_flag (bit 7) is “0”, the transponder returns only the data in the specified blocks to the reader/writer. The value of the “number of blocks” field specified in the request is the expected number of blocks minus 1. Setting the number of blocks to “01H” makes a request to read 2 blocks. Setting the number of blocks to “00H” makes a request to read 1 block (the request having the same effect as the Fast Read Single Block command). • Request [Request from the reader/writer to the transponder] UID Command IC manufacturer (Addressed SOF Flag (Fast Read code (necessary) mode) Multiple Blocks) 8 bits 8 bits (“C3H”) 8 bits (“08H”) 64 bits First block number Number of blocks CRC 8 bits 8 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF (2) When Error_flag not set SOF Flag 8 bits (“00H”) Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits EOF Block security status(option) Data CRC 8 bits 256 bits 16 bits EOF Repeated as required DS411-00004-0v03-E 43 MB89R112 3-6. Read Lock Block Command On receiving the Read Lock Block command, the transponder locks (read disable) permanently the data stored in one specified single-block. The transponder performs verification after writing and returns an error code if the writing has failed. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the lock operation starting after “t1nom (320.9 μs) + a multiple of 4096/fc (302.1μs)” with total tolerance of ± 32/fc (2.4 μs) and latest within 20 ms. If it is “1”,the transponder shall wait for the reception of an EOF from the reader/writer, and upon such reception still return its response (However, if an EOF is not sent within 38 ms, the time-out occurs and the transponder can receive another command). Once the Read Lock Block command has been received, data in the locked block cannot read by the Read Single Block command. On the other hand, if the locked block is accessed as part of the selected blocks by the Read Multiple Blocks command, the data of the locked block is indicated as “00H” among the batch of the data. • Request [Request from the reader/writer to the transponder] Command IC manufacturer SOF Flag (Read Lock Block) code 8 bits 8 bits (“D9H”) UID (Addressed mode) Block number CRC 64 bits 8 bits 16 bits 8 bits (“08H”) EOF • Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF Flag Error code 8 bits (“01H”) (2) When Error_flag not set SOF 44 CRC 8 bits EOF 16 bits Flag CRC 8 bits (“00H”) 16 bits EOF DS411-00004-0v03-E MB89R112 3-7.

Therefor it is recommended for the customers to optimize the antenna and reader/writer according to the required communication distance and usage environment. - If the user intends to access multiple transponders from a reader/writer, the interference between transponders or between the reader/writer and a transponder may degrade communication performance (transmission distance and communication time) . Therefore, a user who intends to design a system using multiple transponders should consider this point. • FRAM Characteristics Item Value Min ⎯ Read/Write Endurance*1 Data Retention*2 Max 10 ⎯ 30 ⎯ Unit Parameter Times/byte Operation Ambient Temperature TA = + 85 °C Years Operation Ambient Temperature TA = + 85 °C Operation Ambient Temperature TA = + 70 °C*3 *1 : Total number of reading and writing defines the minimum value of endurance, as an FRAM memory operates with destructive readout mechanism. *2 : Minimum values define retention time of the first reading/writing data right after shipment. *3 : This value is calculated by reliability test results for reference as well. • Differences of the function between ISO/IEC15693 and MB89R112.
