The FRAM memory areas consist of a total of 64 blocks (58 blocks of user area and 6 blocks of system area). Each block can store 32 bits (4 bytes) of data. The block is the unit used for the writing and reading of FRAM data. The memory map of the FRAM is shown below. • FRAM configuration Area Block No. Details Data read Data write User area (232 bytes) System area (24 bytes) 00H to 39H User area Yes Yes 3AH RFU* Yes No 3BH UID1 (1 to 32 bit) Yes No 3CH UID2 (33 to 64 bit) Yes No 3DH EAS, AFI, DSFID, IC Reference Yes Limited 3EH,3FH Block security status Yes No * : Reserved for future use Blocks “00H” to “39H” are user area. The user area is defined as an area that can be accessed when the corresponding block address is specified. On the other hands, Blocks “3AH” to “3FH” are system area. The system area is defined as an area that can be accessed only with a specific command (request). The system area consists of 6 blocks and contains UID, AFI, DSFID, EAS, IC reference and security status (can write or cannot write) data for individual block. UID, IC reference and RFU is fixed and cannot be updated. AFI, DSFID, and EAS bit are written at the factory, and can be updated and locked (disable to write) with commands. (Only EAS bit cannot be locked.) As shown in above, “3BH” and “3CH” hold the UID, and “3EH” and “3FH” hold the security status information on individual user areas, AFI, and DSFID. As shown in “• Structure of 3DH”, “3DH” contains EAS bit, AFI, DFID and IC reference. As shown in the next following figure system areas, “3EH” and “3FH” contains block security status data. • Structure of “3DH” MSB 32 EAS Status LSB 31 25 24 Internally used 17 16 IC Reference 9 8 DSFID 1 AFI 3 MB89R119 • Structure of “3EH” and “3FH” MSB 32 3EH Block security status (BBS) of user block 1FH 3FH AFI Lock Status LSB 31 • • • 26 • • • • • • DSFID Lock Status RFU* (4 bits) 1 BBS of 00H BBS of 39H • • • BBS of 20H * : Reserved for future use The security status of the user area for 58 blocks is stored in the block security status bits in 2 system area blocks of “3EH” and “3FH”. A user area is unlocked when the corresponding block security status bit is “0”; it is locked (disable to write state) when the corresponding block security status bit is “1”. In the same way, the security status of AFI and DSFID are stored in “AFI Lock Status” and “DSFID Lock Status” respectively. It is possible to read up to 64 blocks data by one command and to write up to 2 blocks data by one command. EAS bit is a single bit, and it is used for setting EAS status. 4 MB89R119 ■ DATA ELEMENT DEFINITION 1. Unique Identifier (UID) The MB89R119 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’s code whose value is always “08H”, which is defined by ISO/IEC 7816-6/AMI (bit 49 to bit 56) • Unique 48-bit serial number assigned by Fujitsu (bit 1 to bit 48) Among the unique 48-bit serial number assigned by Fujitsu, the 1 byte from bit 41 to bit 48 defines MB89R119 code whose value is “02H”. And the 5 bytes from bit 1 to bit 40 define Chip Information. • Structure of UID MSB LSB 64 57 56 “E0H” 49 48 IC manufacturer code “08H” 41 40 “02H” 1 Chip information Unique serial number assigned by Fujitsu 5 MB89R119 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 memory (FRAM). The factory default setting of the AFI is “00H”. • Types of AFI Application Application Family Sub-Family Application Use Field Example/Note (b8-b5) (b4-b1) “0” “0” All families and sub-families No application 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 “A” “0”, Y ISO/IEC JTC1/SC31 “B” “0”, Y IATA Managed by ISO/IEC JTC1/SC31 “C” “0”, Y UPU Managed by ISO/IEC JTC1/SC31 “D” “0”, Y RFU* Managed by ISO/IEC JTC1/SC31 “E” “0”, Y RFU* Managed by ISO/IEC JTC1/SC31 “F” “0”, Y RFU* Managed by ISO/IEC JTC1/SC31 Wide applicative preselection Access control Public telephone, GSM Internet services Portable files EAN-UCC system for application identifiers Managed by ISO/IEC JTC1/SC31 Data identifiers as defined in ISO/IEC 15418 * : 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 memory (FRAM). The factory default setting of the DSFID is “01H”. 6 MB89R119 4. Cyclic Redundancy Check (CRC) When a frame is received, reception of correct data--that is, the characters 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 and the detail is defined in ISO/IEC 15693-3 and ISO/IEC 18000-3. 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 LSBit CRC 16 (8 Bits) MSBit CRC 16 (8 Bits) First transmitted bit of the CRC 5. Electronic Article Surveillance (EAS) status EAS status is 1 bit data, which is stored in the system area of memory (FRAM) . The initial value is “1”. EAS bit “1” means goods-monitoring status, and EAS bit “0” means that goods-monitoring status is cleared. EAS status can be written by Write EAS command and can be checked “3DH” block (refer to “■ MEMORY MAP”) by Read commands such as Read Signal Block command. Together with Gate type reader/writer, EAS command can support anti-theft security functions. 7 MB89R119 ■ ABSOLUTE MAXIMUM RATINGS Parameter Symbol Ratings Min Max Unit Maximum antenna input current Imax ⎯ 90 mA0−p ESD voltage immunity VESD ±2 ⎯ kV Storage temperature Tstg − 40 + 85 °C Remarks Human body model WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings.

(Not supports 1-out-of-256 mode.) • 1-out-of-4 mode : In 1-out-of-4 mode, 2-bit 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 (0 = LSB) 66.08 µs 9.44 µs 75.52 µs • Data frame : A data frame begins with a start-of-frame (SOF) signal and ends with an end-of-frame (EOF) signal. The MB89R119 is enabled to receive a frame from a reader/writer in 300 µs after the MB89R119 has sent a frame to the reader/writer. The MB89R119 is also enabled to receive a frame from a reader/writer within 1 ms after power has been supplied to the MB89R119. • 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 9.44 µs 9.44 µs 11 MB89R119 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 MB89R119 supports only a 1-subcarrier system. (Not supports 2-subcarrier system.) • Data rate : The MB89R119 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). Also the Fast commands (Custom commands) supports the 2 data rate modes specified by the Data_rate_flag. 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) • Bit coding : The Manchester coding is used for the bit coding. The following figure shows the signals modulated in high data rate mode when standard command is used, and the next following figure shows the same signals when fast command is used. In low data rate mode of both standard commands and fast commands, the number of pulses for subcarrier and data transfer time is 4 times as large as the number in high data rate mode. • Signal waveforms by load modulation in high data rate mode (standard 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 12 MB89R119 • 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 figure shows the SOF and EOF signals sent in high data rate mode when standard command is used, and the next following figure shows the same signals when fast command is used. In low data rate mode of both standard commands and fast commands, the number of pulses and data transfer time is 4 times as large as the number in high data rate mode, which is the same as explained in the figure below. A reader/writer that has sent a frame to a transponder must be enabled to receive a frame from the transponder within 300 µs after the reader/writer has completed sending of the frame. • Waveforms of SOF and EOF signals of a frame sent from a transponder (standard 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 13 MB89R119 3. FRAM Data Protection if Power Lost During Data Writing If the power to nonvolatile memory is lost while data is being written to it, data may take on unexpected values, possibly adversely affecting system operation. The MB89R119’s FRAM is accessed (updated) in byte units. The MB89R119 circle confirms that the level of power supply voltage is sufficient before data is written to each byte. However, since write commands access more than one byte at once a power loss in the middle of write commands may result in a mixture of new written data and still remaining old data. As a result, confirm success of a write command with read command after each write command. 4. Requests/Responses A request is sent from the reader/writer to the transponder. In reply to the request, the transponder sends a response to the reader/writer. Each request, and each response, is transmitted in a 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 option 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. Set the RFU_flag always to “0”. 5. Operating Modes The MB89R119 has the following 2 operating modes : Each mode specifies a different mechanism for how the transponder returns a response in reply to a request from the reader/writer : • Addressed mode The MB89R119 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 MB89R119 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 response in accordance with the command in the request. 14 MB89R119 6.

Response Format Figure shows a typical example of the response data format, and table shows the definition of the response flag bits. If the error flag is set to “1”, an error code field is generated in the response. If the error flag is set to “0”, this means no error, and If the error flag is set to “1”, this means any error generation. Error codes and their meaning are showed in Table. • Structure of the response frame SOF 16 Flag Parameter Data CRC EOF MB89R119 • Response flag definitions Bit number Flag name State Description 0 Error not found 1 Error found RFU* 0 Set to “0” Bit 3 RFU* 0 Set to “0” Bit 4 Extension_flag 0 Set to “0” Bit 5 RFU* 0 Set to “0” Bit 6 RFU* 0 Set to “0” Bit 7 RFU* 0 Set to “0” Bit 8 RFU* 0 Set to “0” Bit 1 Error_flag Bit 2 * : Reserved for future use • Error code definitions Error code Meaning “01” The specific command is not supported.

Anti-Collision Algorithm The MB89R119 executes an anti-collision sequence loop based on an algorithm that complies with ISO/IEC 15693-3. 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 request (command) to transponders, and some transponders return responses while other transponders do not according to the algorithm explained in "10. Execution of Inventory Command by a Transponder". 17 MB89R119 9. REQUEST PARAMETER • Request Parameter Settings Set the reader/writer as follows before issuing the Inventory command. • The Nb_slots_flag (bit6), 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 indicates the significant bits of the mask value. • The mask value is integer bytes of data, transmitted beginning with the lowest bit. If the mask length is not a multiple of 8 (bits), 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 8 bits Command code Mask length Mask value CRC 8 bits 8 bits 0 to 64 bits 16 bits • Example of the Mask Value with Padding MSB 18 LSB 0000 0100 1100 1111 Pad Mask value EOF MB89R119 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? Yes NbS = 1 SN_length=0 LSB (UID, SN_length + mask length) = LSB (SN, SN_length) & LSB (mask, mask length) ? Yes Response transmission No NbS = 16 SN_length=4 No Wait (Slot_Frame) Slot_Frame=SOF? Yes No Slot_Frame=EOF? No Yes End of processing End of processing SN < NbS-1 No Yes SN = SN + 1 End of processing 19 MB89R119 • Comparison of the mask value and the number of slots with the UID [Inventory command (the side of a reader/writer)] Padding Inventory command includes the mask value and mask length. The mask value is padded with “0” into the higher bit side so to make the byte-unit length (a multiple of 8 bits). If Inventory command is received, the slot counter is reset to “0”. 000••• Mask length Slot counter If EOF is received, the increment of the slot counter is started by the transponder. The value is compared with the least significant bits of UID of the transponder. If the value is in accord with the mask value, the response is returned by the transponder. Mask value (specified by the Inventory command) Number of Mask value (no padding) slots Ignored Compared Unique Identifier (UID) [Unique Identifier (the side of a transponder) ] 20 MB89R119 11. Anti-Collision Sequence • Execution of anti-collision sequence A typical anti-collision sequence that is applied when the number of slots is 16 is executed as follows : 1) The reader/writer sends an Inventory command. The Nb_slots_flag 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 transmits its 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 transmits its 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 a SOF signal and exit the anti-collision sequence. In this case, since the request is addressed to transponder 1 (Address 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 clause 12. 21 MB89R119 • Example of Anti-Collision Sequence Slot_Counter Reader/Writer Slot 0 (1) SOF Inventory Command (2) EOF Slot 1 (3) (4) EOF Response 1 Response 2 MB89R119 Response 3 Timing Slot_Counter Reader/Writer t2_a t1_a Status (5) Slot 2 EOF EOF (7) EOF Response 4 Response 5 Timing t3_a Status t2_a t1_a No response Collision (8) Command transmission Slot_Counter Reader/Writer SOF Command (to Transponder1) (9) EOF Response (Transponder1) MB89R119 Status 22 t2_a t1_a t2_a Collision Slot 3 (6) MB89R119 Timing t1_a No Collision MB89R119 12. Timing definitions (1)Transponder waiting time before transmitting its response after reception of an EOF from the reader/writer : t1_a After detection of an EOF signal sent from the reader/writer, each transponder 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 following.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). If the transponder detects a carrier modulation for ASK 100% or 10% within the time t1_a, it shall reset its t1_a timer and wait for further time t1_a before starting to transmit its response to a reader/writer. MB89R119 defines the same waiting time t1_a for Write commands as followings, although the maximum value is not defined in ISO/IEC 15693-3 and ISO/IEC 18000-3 mode1. 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).Timing conditions for Write command in which the option_flag is “1”, has optional field are defined in the command descriptions. (2) Transponder modulation ignore time after reception of an EOF from the reader/writer : tmit After detection of an EOF signal sent from the reader/writer, MB89R119 shall ignore any received 10%, modulation during tmit. tmit starts from the detection of the rising edge of the EOF, and the minimum value is defined as 4384/fc (=323.3 µs) + tnrt. tnrt stands for the response time of MB89R119. (3) Reader/writer waiting time before sending a subsequent request : t2_a When the reader/writer has received a response from the transponder to a previous request other than Inventory and 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 mode1. When the reader/writer has sent Stay Quiet command or Kill command, which causes no response from the transponder, or MB89R119 does not return any response, MB89R119 can receive a command in 309.2 µs from the detection of the rising edge of the EOF. (4) Reader/writer waiting time before sending a request(switching to the next slot) during an Inventory process : t2inv During Inventory process, the reader/writer sends an EOF to switch to the next slot. In this case, the waiting time is defined as follows depending on whether transponders return responses. - Waiting 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 mode1 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 or tnrt passes). After that, the reader/writer must wait as additional t2_a, and then send a 10% or 100% ASK modulated EOF to switch to the next slot. - Waiting time applied for when the reader/writer has not received any responses : t3_a When the reader/writer has not received any responses from the transponders, the reader/writer must wait until t3_a passes before sending an EOF signal. In this case, t3_a starts from the rising edge of the last sent EOF. The minimum value of t3_a is defined as shown in the following table. (a) If the reader/writer sends a 10% modulated EOF, the minimum value of t3_a(ASK 10%) is ’4384/fc (= 323.3 µs) + tnrt’ as shown in “• Timing specification”. (b) If the reader/writer sends a 100% modulated EOF, the minimum value of t3_a(ASK 100%) is ’4384/fc (= 323.3 µs) + tsof’ as shown in “• Timing specification”. tnrt : The nominal response time of transponder tsof : The time duration for transponder to transmit a SOF to the reader/writer 23 MB89R119 • t3_a for ASK10% and ASK100% signal Reader/Writer SOF Inventory command new command (or EOF signal) EOF no response MB89R119 t1_a t3_a (ASK 100 %) Timing t3_a (ASK 10 %) tsof tnrt Ignore ASK 10 % signal MB89R119 ASK signal handling reset t1_a after receiving ASK 100 % signal ignore ASK 100 % signal possible to receive ASK 10 % 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 ⎯ ⎯ ⎯ Low data rate : 15708.16 µs High data rate : 3927.04 µs Fast Low data rate : 7854.08 µs Fast High data rate : 1963.52 µs ⎯ ⎯ Low data rate : 604.16 µs High data rate : 151.04 µs Fast Low data rate : 302.08 µs Fast High data rate : 75.52 µs ⎯ tnrt tsof 24 MB89R119 ■ COMMAND LIST Mandatory and Optional commands defined by ISO/IEC 15693-3 are supported (Partly not supported*). * : Refer to “■ NOTE ON USING •Comparison between ratings of ISO/IEC 15693 and specification of MB89R119”.

Description of Mandatory Command (1) Inventory command • Description of command The Inventory command executes the anti -collision sequence. Even though an error is detected during execution of this command, a response indicating the error is not returned. The Inventory_flag (bit3) must be set to “1”. When the AFI_flag (bit5) in the Inventory command frame is set as “1“, the response is returned in the following cases. •The AFI value of the transponder is in accord with the Optional AFI value. •The 4 bits value MSB of the Optional AFI is “0H”, and the 4 bits value LSB of the Optional AFI is in accord with the 4 bits value LSB of the transponder. •The 4 bits value LSB of the Optional AFI is “0H”, and the 4 bits value MSB of the Optional AFI is in accord with the 4 bits value MSB of the transponder. •The Optional AFI value is “00H”. For example, if the AFI value of the transponder is “69H”, the response is returned when the Optional AFI value is “69H”, “60H”, “09H” or “00H”. • Command [Request from the reader/writer to the transponder] Command SOF Flag Optional AFI (Inventory) 8 bits 8 bits (“01H”) 8 bits Mask length Mask value CRC 8 bits 0 to 64 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] SOF Flag DSFID 8 bits (“00H”) 8 bits UID CRC 64 bits 16 bits EOF (2) Stay Quiet command • Description of 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 and executes only a command for which the Address_flag (bit 6) is set. The transponder exits the quiet state only in the following cases : • The transponder enters the power-off state. • The transponder receives the Reset to Ready command and enters the ready state. • Command [Request from the reader/writer to the transponder] SOF Flag Command (Stay Quiet) UID (necessary) 8 bits 8 bits (“02H”) • Response [Response from the transponder to the reader/writer] No response 26 64 bits CRC 16 bits EOF MB89R119 2. Description of Optional Command (1) Read Single Block command • Description of command On receiving the Read Single Block command, the transponder returns the data stored in the specified singleblock to the reader/writer as a response. • Command [Request from the reader/writer to the transponder] Command UID SOF Flag (Read Single Block) (Addressed mode) 8 bits 8 bits (“20H”) Number of blocks CRC 8 bits 16 bits 64 bits EOF • Response [Response from the transponder to the reader/writer] (a) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits (b) When Error_flag not set SOF Flag Data CRC 8 bits (“00H”) 32 bits 16 bits EOF EOF (2) Write Single Block command • Description of 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 + 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 20 ms, the time-out occurs and the transponder can receive another command.) Note : t1nom = 320.9 µs (typical) • Command [Request from the reader/writer to the transponder] Command UID SOF Flag (Write Single Block) (Addressed mode) 8 bits 8 bits (“21H”) Number of blocks Data CRC 8 bits 32 bits 16 bits 64 bits EOF • Response [Response from the transponder to the reader/writer] (a) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits EOF 27 MB89R119 (b) When Error_flag not set SOF Flag CRC 8 bits (“00H”) 16 bits EOF (3) Lock Block command • Description of command On receiving the Lock Block command, the transponder locks 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 + 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 20 ms, the time-out occurs and the transponder can receive another command.) Once the Lock Block command has been received, data in the locked block cannot be changed by the Write Single(Multiple) Block command. • Command [Request from the reader/writer to the transponder] Command UID SOF Flag (Lock Block) (Addressed mode) 8 bits 8 bits (“22H”) 64 bits Number of blocks CRC 8 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] (a) When Error_flag set SOF (b) When Error_flag not set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits Flag CRC 8 bits (“00H”) 16 bits EOF EOF (4) Read Multiple Blocks Command • Description of command On receiving the Read Multiple Blocks command, the transponder returns the data stored in the specified successive blocks to the reader/writer as a response. Up to 64 blocks of data can be read for one request. 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 “06H” makes a request to read 7 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). The maximum number of blocks to be set is “3FH”. Note : For execution in the addressed mode, the Read Multiple Blocks command must be run without shutting off the RF power supply after obtaining the UID, for example, using the Inventory command. No response may be expected when RF power supply is not stable. 28 MB89R119 • Command [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] (a) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits (b) When Error_flag not set SOF Flag 8 bits (“00H”) *: n is the number of blocks to be responsed. Data CRC 32xn bits * 16 bits EOF EOF (5) Write Multiple Blocks Command • Description of command On receiving the Write Multiple Blocks command, the transponder writes the successive multiple-block data included in the request to the specified blocks. Up to 2 blocks of data can be written for one request. The transponder performs verification after writing and returns an error code if the writing has failed. The number of blocks specified in the Write Multiple Blocks command is similar to the number of blocks specified in the Read Multiple Blocks command. The value of the number of blocks field specified in the Write Multiple Blocks command is obtained by subtracting 1 from the number of the expected blocks to be written. Setting the number of blocks to “01H” makes a request to write 2 blocks. Setting the number of blocks to “00H” makes a request to write 1 block (the request having the same effect as the Write Single Block command). If at least one of the blocks specified by the command is locked, the transponder does not write any data and, instead, returns an error code. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation starting after <t1nom + 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.

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 20 ms, the time-out occurs and the transponder can receive another command.)

The transponder performs verification after writing and returns an error code if the writing has failed. The EAS bit must be set to “00H” to cancel anti-theft or goods-monitoring mode. The bit must be set to “01H” to set up the goods-monitoring mode. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of -32/fc to +32/fc (2.4 µs) and latest within 20 ms.

Even if the transponder is moved in the magnetic field (power-on state) again after being removed out of the magnetic field (power-off state), the transponder stays in the Dead state and never respond to any commands from the reader/writer. • Command [Request from the reader/writer to the transponder] SOF Flag Command(Kill) IC Mfg code (necessary) UID (necessary) CRC 8 bits 8 bits (“A6H”) 8 bits (“08H”) 64 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] (a) When Error_flag set SOF Flag Error code CRC 8 bits 8 bits 16 bits EOF (b) When Error_flag not set No response WARNING: The transponder received Kill command is disabled and cannot be used again. (4)Fast Inventory Command • Description of command The Fast Inventory command is the same as the Inventory Command that executes the anti-collision sequence. The datarate in the response is twice as defined in ISO/IEC 15693-3. Even though an error is detected during execution of this command, a response indicating the error is not returned. The Inventory_flag (bit3) must be set to “1”. When the AFI_flag (bit5) in the Inventory command frame is set as “1“, the response is returned in the following cases. • The AFI value of the transponder is in accord with the Optional AFI value. • The 4 bits value MSB of the Optional AFI is “0H”, and the 4 bits value LSB of the Optional AFI is in accord with the 4 bits value LSB of the transponder. • The 4 bits value LSB of the Optional AFI is “0H”, and the 4 bits value MSB of the Optional AFI is in accord with the 4 bits value MSB of the transponder. • The Optional AFI value is “00H”. For example, if the AFI value of the transponder is “69H”, the response is returned when the Optional AFI value is “69H”, “60H”, “09H” or “00H”. 36 MB89R119 • Command [Request from the reader/writer to the transponder] Command IC manufacturer SOF Flag (Fast Inventory) code (necessary) 8 bits 8 bits (“B1H”) 8 bits (“08H”) Optional AFI Mask length Mask value CRC 8 bits 8 bits 0 to 64 bits 16 bits EOF • Response [Response from the transponder to the reader/writer] SOF Flag DSFID 8 bits (“00H”) 8 bits UID CRC 64 bits 16 bits EOF (5) Fast Read Multiple Blocks Command • Description of command The Fast Read Multiple Blocks command is the same as the Read Multiple Blocks Command that reads the specified successive blocks. The datarate in the response is twice as defined in ISO/IEC 15693. Up to 64 blocks of data can be read for one request. 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 “06H” makes a request to read 7 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). The maximum number of blocks to be set is “3FH”. Note : For execution in the addressed mode, the Fast Read Multiple Blocks command must be run without shutting off the RF power supply after obtaining the UID, for example, using the Inventory command. No response may be expected when RF power supply is not stable. • Command [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”) 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] (a) When Error_flag set SOF Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits (b) When Error_flag not set SOF Flag Data 8 bits (“00H”) 32xn bits * *: n is the number of blocks to be responsed. CRC EOF EOF 16 bits 37 MB89R119 (6)Fast Write Multiple Blocks Command • Description of command The Fast Write Multiple Blocks command is the same as the Write Multiple Blocks Command, that writes the successive multiple-block data. The datarate in the response is twice as defined in ISO/IEC 15693. Up to 2 blocks of data can be written for one request. The transponder performs verification after writing and returns an error code if the writing has failed. The number of blocks specified in the Fast Write Multiple Blocks command is similar to the number of blocks specified in the Read Multiple Blocks command. The value of the number of blocks field specified in the Fast Write Multiple Blocks command is obtained by subtracting 1 from the number of the expected blocks to be written. Setting the number of blocks to “01H” makes a request to write 2 blocks. Setting the number of blocks to “00H” makes a request to write 1 block (the request having the same effect as the Fast Write Single Block command). If at least one of the blocks specified for data writing is locked, the transponder does not write any data and, instead, returns an error code. If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation starting after <t1nom + a multiple of 4096/fc (302.1 µs)> with total tolerance of − 32/fc to + 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 returns its response. (However, if an EOF is not sent within 20 ms, the time-out occurs and the transponder can receive another command.) • Command [Request from the reader/writer to the transponder] Command UID First IC manufacturer Number SOF Flag (Fast Write (Addressed block code of blocks Multiple Blocks) mode) number 8 bits 8 bits (“C4H”) 8 bits (“08H”) 64 bits 8 bits 8 bits Data CRC EOF 32 or 64 bits 16 bits • Response [Response from the transponder to the reader/writer] (a) When Error_flag set SOF (b) When Error_flag not set SOF 38 Flag Error code CRC 8 bits (“01H”) 8 bits 16 bits Flag CRC 8 bits (“00H”) 16 bits EOF EOF MB89R119 4. Command Execution Time (1) Write Multiple Blocks Command Execution Time The minimum time (processing in the address mode) required to complete data writing to all user areas (232 bytes) of the FRAM and verification with the Write Multiple Blocks command is estimated to be 302 ms. (2) Read Multiple Blocks Command Execution Time The minimum time (processing in the address mode) required to complete data reading for all user areas (232 bytes) of the FRAM with the Read Multiple Blocks command is estimated to be 76 ms. In addition, with the Fast Read Multiple Blocks command is estimated to be 41 ms. 39 MB89R119 ■ STATE TRANSITION DIAGRAM • Definition of states Each state of MB89R119 is defined as follows. • Power-Off the state : IF the power-off state, a transponder can not fulfill the function so that the voltage from a reader/writer is underpowered. • Ready state : In the ready state, the MB89R119 can execute all commands from a reader/writer • Quiet state : In the quiet state, the MB89R119 can execute the command from a reader/writer in which the Inventory_flag is not set and the Address_flag is set. • Dead state : In the dead state, the MB89R119 can not execute any command from a reader/writer. As shown in the figure below, the MB89R119 moves from one state to another according to the status of power and by a command. • State transition diagram Power-Off state Out of field In field Out of field Out of field In field Any other command Kill command Ready state Reset to Ready command Dead state Stay Quiet (UID) command All commands Quiet state Any other command where Address_flag is set and where Inventory_flag is not set. 40 MB89R119 ■ NOTES ON USING • Notes on the radio interface - It is the user’s responsibility to reduce the effects of the electromagnetic waves produced by the reader/writer. - The user must optimize the shapes of the antenna coils for transponder and reader/writer so that they match the transmission distance and installation space required for the user’s application. - 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 reliability Up to 1010 writes to the FRAM memory and 10 years of data retention at + 55 °C are guaranteed. For the data retention characteristics at + 150 °C or higher, see “■ SHIPPING METHOD AND RECOMMENDED ASSEMBLY CONDITIONS”. • Difference between rating of ISO/IEC 15693 and MB89R119 implementation.
