The FRAM memory areas consist of a total of 256 blocks (250 blocks of user area and 6 blocks of system area). Each block can store 64 bits (8 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 (2000 bytes) 00H to F9H FAH System area (48 bytes) FBH FCH to FFH User area UID (64 bits) AFI, DSFID, EAS, security status Block security status Yes Yes Yes Yes Yes No Limited No Blocks "00H" to "F9H" 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 "FAH" to "FFH" 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 bit, and security status (can write or cannot write) data for individual block. UID 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, "FAH" holds the UID, and "FCH" to "FFH" hold the security status information on individual user areas. As shown in "* Structure of FBH", "FBH" contains AFI, AFI lock status byte, DSFID, DSFID lock status byte, and EAS bit.

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". It is possible to read/write data of 2 blocks (128 bits) at one time in the user area. (If Read Multiple Blocks Unlimited command is used, up to 256 blocks can be accessed at one time.) EAS bit is a single bit, and it is used for setting EAS status. 4 MB89R118 DATA ELEMENT DEFINITION 1. Unique Identifier (UID) The MB89R118 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", and 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 MB89R118 code whose value is "01H". And the 5 bytes from bit 1 to bit 40 define Chip Information. * Structure of UID MSB 64 "E0H" 57 56 49 48 "01H" 41 40 Chip information Unique serial number assigned by Fujitsu LSB 1 IC manufacturer code "08H" 5 MB89R118 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" X X "0" "1" "2" "3" "4" "5" "6" "7" "8" "9" "A" "B" "C" "D" "E" "F" "0" "0" Y Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y "0", Y All families and sub-families All sub-families of family X Only the Yth sub-families of family X All families of Yth sub-families Transport Financial Identification Telecommunication Medical Multimedia Gaming Data storage Portable files Data identifiers as defined in ISO/IEC15418 Managed by ISO/IEC JTC1/SC31 Managed by ISO/IEC JTC1/SC31 Managed by ISO/IEC JTC1/SC31 Managed by ISO/IEC JTC1/SC31 Managed by ISO/IEC JTC1/SC31 EAN-UCC system for application identifiers Managed by ISO/IEC JTC1/SC31 ISO/IEC JTC1/SC31 IATA UPU RFU* RFU* RFU* Internet services Mass transit, bus, airline IEP, banking, retail Access control Public telephone, GSM No application preselection Wide applicative preselection * : Reserved for future use Note : Both X value and Y value are "1" to "F".

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 MB89R118 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. 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 CRC 16 (8 Bits) MSBit LSBit MSByte MSBit CRC 16 (8 Bits) First transmitted bit of the CRC 5. Electronic Article Surveillance (EAS) status EAS status is 1 bit data (LSB side) , 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 "FBH" 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 MB89R118 ABSOLUTE MAXIMUM RATINGS Parameter Maximum antenna input current ESD voltage immunity Storage temperature Symbol Imax VESD Tstg Ratings Min 2 - 40 Max 90 + 85 Unit mA0-p kV C Human body model Remarks WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess of absolute maximum ratings.

Communication from Reader/Writer to Transponder * Modulation method : Only 10% ASK modulation is supported (100% ASK modulation is not supported) . * Modulation rate (m) should be 10% to 20% for communication with transponder. Modulation rate 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 waveform hr y y t2 t1 t3 b hf a 13.56 MHz Maximum and minimum values of t1, t2 and t3 are shown in the following table. In this table, y is 0.05 (a-b) and the maximum value of hf and hr is 0.1(a-b). * Specification of t1, t2 and t3 Minimum Maximum t1 t2 t3 6.0 s 4.7 s 0 9.44 s t1 3.0 s 9 MB89R118 * Data rate and bit coding : The MB89R118 supports only 1-out-of-4 mode for bit coding. (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 s 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 s 9.44 s 75.52 s * "01B" pulse position (1 = LSB) 28.32 s 9.44 s 75.52 s * "10B" pulse position (0 = LSB) 47.20 s 75.52 s 9.44 s * "11B" pulse position (0 = LSB) 66.08 s 75.52 s 9.44 s * Data frame : A data frame begins with a start-of-frame (SOF) signal and ends with an end-of-frame (EOF) signal. The MB89R118 is enabled to receive a frame from a reader/writer within 300 s after the MB89R118 has sent a frame to the reader/writer. The MB89R118 is also enabled to receive a frame from a reader/writer within 1 ms after power has been supplied to the MB89R118. * Waveforms of SOF and EOF signals of a frame sent from a reader/writer SOF 9.44 s 9.44 s 9.44 s 37.76 s 37.76 s EOF 37.76 s 9.44 s 9.44 s 10 MB89R118 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 MB89R118 supports only a 1-subcarrier system. (Not supports 2-subcarrier system.) * Data rate : The MB89R118 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 s (modulated) 18.88 s (not modulated) 37.76 s * Logic 1 423.75 kHz subcarrier 18.88 s (not modulated) 18.88 s (modulated) 37.76 s * Signal waveforms by load modulation in high data rate response mode (fast commands) * Logic 0 9.44 s 9.44 s 18.88 s * Logic 1 9.44 s 9.44 s 18.88 s 11 MB89R118 * 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 s 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 s 56.64 s 37.76 s * EOF 37.76 s 56.64 s 56.64 s * Waveforms of SOF and EOF signals of a frame sent from a transponder (fast commands) * SOF 423.75 kHz Subcarrier 28.32 s 28.32 s 18.88 s * EOF 423.75 kHz Subcarrier 18.88 s 28.32 s 28.32 s 12 MB89R118 3. FRAM Data Protection if Power Lost During Data Writing If the power to FRAM is lost while data is being written to it, data may take on unexpected values, possibly adversely affecting system operation. The MB89R118's FRAM is accessed (updated) in byte units. The MB89R118 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 MB89R118 has the following 3 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 MB89R118 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. 13 MB89R118 * Non-Addressed mode The MB89R118 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. * Select mode The MB89R118 enters select mode when the Select_flag is set to "1", and the address_flag is set to "0". In select mode, do not include a UID as a request. Of the transponders that receive the command, only the transponder in the selected state executes processing and returns a response in accordance with the command in the request. 6. Request Format Figure shows a typical example of the request data format, and Table shows the definition of request flag bits. * Structure of the request frame SOF Flag Command code Parameter Data CRC EOF * Setting of Bit 1 to Bit 4 Bit number Flag name Bit 1 Bit 2 Bit 3 Bit 4 Sub-carrier_flag Data_rate_flag Inventory_flag Protocol_Extension_flag 1/0 0 1 0 1 0 1 0 1 State/Description One subcarrier selected Two subcarriers selected (not supported) Low data rate (6.62 Kbps) selected High data rate (26.48 Kbps) selected Command other than Inventory command selected Inventory command selected Protocol not extended Protocol extended (RFU*) * : Reserved for future use Note : "Inventory_flag" of bit3 is determined whether "Inventory command" (select "1") or other command (select "0") is used. 14 MB89R118 * Setting of Bit 5 to Bit 8 (When Inventory command is selected [Inventory_flag = "1"]) Bit number Flag name 1/0 State/Description 0 Bit 5 AFI_flag 1 0 1 0 1 Bit 8 RFU* 0 1 AFI not set AFI set (no response when it is not in accord with AFI of the transponder) 16-slots (for one or more transponders) 1-slot (for one transponder) Command option not supported (for the command not supporting the Option_flag) Command option supported Set to "0" Bit 6 Nb_slots_flag Bit 7 Option_flag * : Reserved for future use * Setting of Bit 5 to Bit 8 (When the command other than Inventory command is selected [Inventory_flag = "0"]) Bit number Flag name 1/0 State/Description 0 Bit 5 Select_flag 1 0 1 0 1 Bit 8 RFU* 0 1 Command flag decided by the setting of bit 6 and later bits.

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 "00H", this means no error, and If the error flag is set to "01H", this means any error generation. Error codes and their meaning are showed in Table. * Structure of the response frame SOF Flag Parameter Data CRC EOF 15 MB89R118 * Response flag definitions Bit number Flag name Bit 1 Bit 2 Bit 3 Bit 4 Bit 5 Bit 6 Bit 7 Bit 8 Error_flag RFU* RFU* Extension_flag RFU* RFU* RFU* RFU* State 0 1 0 0 0 0 0 0 0 Error not found Error found Set to "0" Set to "0" Set to "0" Set to "0" Set to "0" Set to "0" Set to "0" Description * : Reserved for future use * Error code definitions Error code "01" "02" "03" "0F" "10" "11" "12" "13" "14" Others The specific command is not supported.

Anti-Collision Algorithm The MB89R118 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. A transponder itself can recognize the existence of other transponders only by information supplied from the reader/writer. Only the reader/writer can recognize the existence of multiple transponders by itself. It is therefore the reader/writer that plays the primary role of algorithm executor. 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". 16 MB89R118 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 is the number of bits in the mask value. * 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 8 bits Command code 8 bits Mask length 8 bits Mask value 0 to 64 bits CRC 16 bits EOF * Example of the Mask Value with Padding MSB 0000 Pad 0100 1100 1111 LSB Mask value 17 MB89R118 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 SN = 0 : Total number of slots (1 or 16) : Current slot number : The "n" least significant bits of value : Concatenation operator : SOF or EOF Nb_slots_flag=1? Yes NbS = 1 SN_length=0 No NbS = 16 SN_length=4 LSB (UID, SN_length + mask length) = LSB (SN, SN_length) & LSB (mask, mask length) ? No Wait (Slot_Frame) No No Yes Response transmission Slot_Frame=SOF? Yes Slot_Frame=EOF? Yes End of processing End of processing SN < NbS-1 Yes SN = SN + 1 No End of processing 18 MB89R118 * Comparison of the mask value and the number of slots with the UID [Inventory command (the side of a reader/writer)] 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). Padding Mask value (specified by the Inventory command) 000*** If Inventory command is received, the slot counter is reset to "0". Mask length Slot counter If EOF is received, the increment of the slot counter is started by the transponder. Number of Mask value (no padding) slots Ignored Compared The value is compared with the lowest bit in UID of the transponder. If the value is in accord with the mask value, the response is returned by the transponder. Unique Identifier (UID) [Unique Identifier (the side of a transponder) ] 19 MB89R118 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 returns a response. Other transponders do not respond. The reader/writer recognizes the UID of transponder 1. 3) The reader/writer sends an EOF signal to proceed to the next slot. 4) In slot 1, transponders 2 and 3 respond. Because the reader/writer cannot recognize the UIDs of the 2 transponders, it remembers that a collision has occurred in slot 1. 5) The reader/writer sends an EOF signal to proceed to the next slot. 6) In slot 2, the reader/writer does not detect any response from transponders and sends an EOF signal to proceed to the next slot. 7) In slot 3, transponders 4 and 5 respond causing another collision. 8) The reader/writer sends a request (for example, a Read Block command, described later) to transponder 1 whose UID that it has already recognized. 9) When an SOF signal is received, all transponders exit the anti-collision sequence. If transponder 1 is specified using addressed mode, only transponder 1 can return a response to the reader/writer. 10) Every transponder is enabled to receive another request from the reader/writer. If the Inventory command is executed again, the sequence starts at slot 0. 11) The mask value is the data whose size is a number of bytes integer and which is sent in LSB-first mode. If the size of the data to be masked is not a multiple of 8 (bits), the unnecessary bits on the MSB side of the mask value are padded with "0" to make the mask value byte data. 20 MB89R118 * Example of Anti-Collision Sequence Slot 0 Reader/ writer SOF Inventory request Slot 1 EOF EOF Slot 2 EOF Response 1 Transponder Response 2 Response 3 Timing Status Slot 3 Reader/ writer EOF t1_a tnrt t2_a t1_a tnrt t2_a t3_a No collision Collision No response SOF Request EOF Response 4 Transponder Response Response 5 Timing Status t1_a t1_a Collision * Timing definitions * Period during which the transponder 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, 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. The following table lists the defined minimum, nominal, and maximum values of t1_a. Also, ISO/IEC 15693-3 specifies that if the transponder detects a modulated signal from the reader/writer within t1_a, the transponder must reset the t1_a timer and wait for another t1_a period before sending a response to the reader/writer; otherwise, the slot counter must be incremented. On the MB89R118, however, the transponder ignores all modulated signals sent from the reader/writer during the following tmit. 21 MB89R118 * Period during which the transponder ignores modulated signals after an EOF signal transmitted from the reader/writer : tmit After detection of an EOF signal sent from the reader/writer, each transponder must ignore the 10% 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 s) + tnrt, as shown in the following table. In the above expression, tnrt stands for the response time of the transponder. * Period during which the reader/writer waits before sending a request : t2_a After a response to a request (except a Inventory command or a Stay Quiet command) from a transponder has been received, the reader/writer must wait for a certain period (t2_a) before sending the next request. The minimum value of t2_a is shown in the following table. If the reader/writer sends a Stay Quiet command to a transponder, the transponder does not return any response. In this case, t2_a begins at the point at which 9.44 s has passed since the rising edge of the EOF pulse for the Stay Quiet command. If the reader/writer sends an Inventory command to a transponder, the wait time t2_a follows the specifications of t2inv (period during which the reader/writer waits before sending a request during execution of the Inventory command) described below. * 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 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 transponders, 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 4384/fc (323.3 s) + tnrt, as shown in the following table. - * Timing Specifications Min t1_a tmit t2_a t2invwr t3_a 4320/fc = 318.6 s 4384/fc(323.3 s)+ tnrt 4192/fc = 309.2 s t2_a + tnrt 4384/fc(323.3 s)+ tnrt Typ 4352/fc = 320.9 s Max 4384/fc = 323.3 s 22 MB89R118 COMMAND LIST All Mandatory and Optional commands defined by ISO/IEC 15693-3 are supported.

If the Option_flag (bit 7) is "0", the transponder shall return its response when it has completed the write operation starting after Data 64 bits CRC 16 bits EOF 25 MB89R118 * Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF Flag 8 bits ("01H") (2) When Error_flag not set SOF Error code 8 bits CRC 16 bits EOF Flag 8 bits ("00H") CRC 16 bits EOF 2-3. 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 CRC 16 bits EOF Flag 8 bits ("00H") CRC 16 bits EOF 26 MB89R118 2-4. 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 2 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 "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). 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. * Command [Request from the reader/writer to the transponder] Command UID SOF Flag (Read Multiple Blocks) (Addressed mode) 8 bits * Response [Response from the transponder to the reader/writer] (1) When Error_flag set SOF Flag 8 bits ("01H") (2) When Error_flag not set SOF Flag 8 bits ("00H") Error code 8 bits CRC 16 bits EOF 8 bits ("23H") 64 bits First block number 8 bits Number of blocks 8 bits CRC 16 bits EOF Block security status (option) 8 bits Repeated as required Data 64 bits CRC 16 bits EOF 2-5. 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.

In addition, with the Fast Read Multiple Blocks command is estimated to be 1.1 seconds, and with the Fast Read Multiple Blocks Unlimited command is estimated to be 0.35 seconds. 40 MB89R118 STATE TRANSITION DIAGRAM * Definition of states Each state of MB89R118 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 MB89R118 can execute all commands from a reader/writer if the Select_flag is not set. * Quiet state : In the quiet state, the MB89R118 can execute the command from a reader/writer for which the Inventory_flag is not set and the Address_flag is set. * Selected state : In the selected state, the MB89R118 can execute the command from a reader/writer for which the Select_flag is set. As shown in figure below, the MB89R118 moves from one state to another according to the status of power and by a command. * State transition diagram Out of field Power-off state Out of field Out of field In field Any other command where Select_flag is not set. Ready state Reset to Ready command Select command (UID) Reset to Ready command where Select_flag is set or Select (different UID) . Stay Quiet (UID) command Select command (UID) Quiet state Stay Quiet (UID) command Selected state Any other command where Address_flag is set and where Inventory_flag is not set. Any other command 41 MB89R118 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 MB89R118 implementation. The table comparing rating of ISO/IEC 15693 to method of MB89R118 is shown in following. Note that the MB89R118 implementation does not support following ratings. * 100% amplitude shift keying (ASK) modulation method * 1-out-of-256 mode data coding * 2-subcarrier * Supports more than 3 blocks for Read/Write Multiple Blocks command (If "Read/Write Multiple Blocks Unlimited command" of Custom commands is used, enables to support more than 3 blocks.) 42 MB89R118 * Comparison between ratings of ISO/IEC15693 and specification of MB89R118 Parameter Details ISO/IEC15693 method Communication method Range of modulation rate Data coding Subcarrier Mandatory command 10% ASK modulation method 100% ASK modulation method (At using of 10% ASK) 1 out of 256 1 out of 4 1-subcarrier 2-subcarrier Inventory command Stay Quiet command Read Single Block command Write Single Block command Lock Block command Read Multiple Blocks command Write Multiple Blocks command Select command Optional command Reset to ready command Write AFI command Lock AFI command Write DSFID command Lock DSFID command Get System Information command Get Multiple block security status command Correspondence Correspondence 10% to 30% Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence MB89R118 method Correspondence Not correspondence 10% to 20% Not correspondence Correspondence Correspondence Not correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence uppermost 2 blocks Correspondence uppermost 2 blocks Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence Correspondence 43 MB89R118 SHIPPING METHOD AND RECOMMENDED ASSEMBLY CONDITIONS * Shipping Method for the MB89R118 : Please inquire separately for the method used to ship the MB89R118. * The MB89R118 is recommended to be mounted in the following condition to maintain the data retention characteristics of the FRAM memory when the chip is mounted. +175 Temperature [ C] +25 120 Time [min] 44 MB89R118 FUJITSU LIMITED All Rights Reserved.
