(not supports 2-subcarrier system.) data rate : the mb89r118 supports th e 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 (des cribed 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) sup ports 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 th e bit coding. the following figure shows the signals modulated in high data rate mode when stand ard command is used, and the next following figure shows the same signals when fast comman d 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 th e number in high data rate mode. 37.76 s 37.76 s ?

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 bi t. 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 t he transponder returns a response in reply to a request from the reader/writer : ? addressed mode the mb89r118 enters addressed mode w hen the address_flag is set to ?1?. in addressed mode, a request includes a uid (the addr ess_flag is set to ?1? simultaneously), and only the transponder that matches the uid in the request retu rns a response. if no transponder that matches the uid exists, a response is not returned. mb89r118 14 ? non-addressed mode the mb89r118 enters non-addressed mode w hen the address_flag is set to ?0?. in non-addressed mode, a request doe s not include a uid. the transponder s that receive the request execute processing and return response in acco rdance 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 form at, and table shows the definition of request flag bits. ?

the nb_slots_flag (bit6), which is a reque st 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 be ginning 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 imme- diately. to proceed to the next slot, the reader/writer sends an eof signal. format of the command sof flag command code mask length mask value crc eof 8 bits 8 bits 8 bits 0 to 64 bits 16 bits msb pad lsb 0000 0100 1100 1111 mask value ?

algorithm for execution of processing by a transponder the following figure shows the algorithm for the execut ion of processing by a transponder when an inventory command is received. the next figure shows the relationship between the uid and the mask value. nb_slots_flag=1?

comparison of the mask value and the number of slots with the uid mb89r118 20 11. anti-collision sequence ? execution of anti-collision sequence a typical anti-collision sequence that is applied when t he 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 ca nnot 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 d oes not detect any response from tr ansponders 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 t he anti-collision sequence. if transponder 1 is specified using addressed mode, only transponder 1 c an return a response to the reader/writer. 10) every transponder is enabled to receive another r equest 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. mb89r118 21 ? 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/write r, each transponder must wait for a certain time (t1_a) before sending a response to the reader/writer. t1_a begi ns 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 de tects a modulated signal fr om 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. t1_a sof eof eof eof t1_a t2_a t2_a t3_a eof eof sof t1_a t1_a tnrt tnrt reader/ writer transponder timing status slot 0 slot 1 slot 2 inventory request response 1 response 2 response 3 no collision collision no response reader/ writer transponder slot 3 request response 5 response response 4 timing status collision ? example of anti-collision sequence mb89r118 22 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 mi nimum value of tmit is defined as 4384/fc (323.3 s) + tnrt, as shown in the following table. in the above expression, tnrt stands fo r 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 comm and or a stay quiet comma nd) from a transponder has been received, the reader/writer must wait for a cert ain 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 tran sponder, the wait time t2_a follows the specifications of t2inv (period during which the reader/writer waits be fore sending a request during execution of the inventory command) described below. period during which the reader/writer waits before s ending a request during execution of the inventory com- mand : 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 follo ws depending on whether trans ponders 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 resp onses, the reader/writer must wait until responses from the transponders have been completed (that is, the re ader/writer receives an eof signal or tnrt passes). after that, the reader/writer must wait until t2_a passes bef ore sending an eof signal to switch to the next slot. - wait time applied when the reader/write r has not received any responses : t3_a when the reader/writer has not received any responses fr om 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 valu e of t3_a is defined as 4384/fc (323.3 s) + tnrt, as shown in the following table. ?
