1 N2091 LICIN NE s hort ange Contactless Memory: Description of the I²C Bus Commands he purpose of this pplication Note is to explain how hort ange Contactless Memories can be accessed through the I²C bus of the. It also describes the set of commands used. INDUCIN o access a hort ange Contactless Memory, the application host microcontroller needs to generate read and write commands on the I²C bus of the. For that purpose the host has to sequentially generate a list of commands in its software, to perform the actions described below: Initialize the arameter egister. When the default alue is set: the is set to the I14443 ype-b mode the external oscillator frequency is 13.56MHz ag nswer s are delimited by F (tart f ) and EF (End f ) the K modulation for equest s is set to 10% the utput F signal is FF a Watchdog delay is set for standard commands witch N the utput F signal by setting arameter egister bit 4 to 1 Generate an INIIE command throught the input/output frame register to put all tag in the INVENY state rigger the anti-collision sequence, if needed, with the use of the lot Marker egister. his sequence allows the application to identify all the tags aailable and generates a list of. elect each identified tags indiidually, with the use of their own, and access their memory contents using read and write commands. Deselect the tags witch the F signal FF, if necessary, by resetting arameter egister bit 4 to 0. his pplication Note describes all command accesses to the hort ange Contactless Memory, or tag, using the I²C serial bus and F transmission.

3 N LICIN NE nti-collision ccess Using the lot Marker egister (03h) he lot Marker egister is used to trigger an automated anti-collision sequence between the and any Microelectronics hort ange Contactless Memory present in the electromagnetic field. he memory must be in the Inentory state before the anti-collision sequence is initiated. hat is, it must hae receied an INIIE command. With one I²C access, the launches a complete stream of commands starting with CLL16(), L_MKE(1), L_MKE(2) and ending with L_MKE(15), and stores all the identified in the utput egister (I²C address 01h). his automated anti-collision sequence simplifies the host software deelopment and reduces the time required to interrogate the 16 slots of the Microelectronics anti-collision mechanism. It is located at the I²C address 03h. When accessed in I²C write mode, the starts generating the anti-collision commands sequentially. fter each command, the waits for the hort ange Contactless Memory nswer that contains the. he alidity of the answer is checked and the answer is stored in the corresponding status slot bit (Byte 1 and Byte 2 as described in able 1.). If the answer is K, the status slot bit is set to 1 and the is stored in the corresponding lot_egister. If no answer or a error is detected, the status slot bit is set to 0 and the corresponding lot_egister is set to 00h for N NWE or to FFh for E. Each time the lot Marker egister is accessed in I²C write mode, Byte 0 of the utput egister is set to 12h, Bytes 1 & 2 proide the status slot information bits and Byte 3 to Byte 18 store the or the error code. ccess in I²C read mode is not possible. o get all the anti-collision data, the utput egister has to be read at the I²C address 01h. able 1.

6 N LICIN NE utput egister (01h) he utput egister is a 36-Byte buffer located at the I²C address 01h. It is accessed serially from Byte 0 up to Byte 35. he first Byte (Byte 0) is used to store the frame length for both transmission and reception. he utput egister is used by the to store the data Bytes of the equest to be sent to the hort ange Contactless Memory. he data Bytes of the nswer receied from the hort ange Contactless Memory are stored automatically by the utput egister. When accessed in I²C write mode, the utput egister stores the equest Bytes that are transmitted to the hort ange Contactless Memory. he equest length (in Bytes) must be written to Byte 0, the equest Bytes are stored from Byte 1. t the end of the transmission, the 16- bit is automatically added by the. fter the transmission, the waits for the hort ange Contactless Memory to send back an nswer. nce this has been correctly decoded, the Bytes it contains are stored into the utput egister from Byte 1. Byte 0 contains the number of Bytes receied from the hort ange Contactless Memory. When accessed in I²C read mode, the utput egister sends back the hort ange Contactless Memory nswer Bytes last receied, if any, with Byte 0 transmitted first. he 16-bit is not stored nor sent back on the I²C bus. he utput egister is set to all 00h between transmission and reception. If there is no answer from the hort ange Contactless Memory, Byte 0 is set to 00h. In the eent of a error, Byte 0 is set to FFh, data are discarded and they are not stored into the register. able 2.

7 N LICIN NE H NGE CNCLE MEMY CMMND E UING HE I²C CCE INIIE() Command Command Code = 06h - 00h INIIE() is used to initiate the anti-collision sequence of the hort ange Contactless Memory. When receiing the INIIE() command, all tags in the EDY state switch to the INVENY state and return their alue. his command is useful specially when there is only one tag in the EDY state in the field range. In this way the of the tag is returned immediately. Figure 3.

8 N LICIN NE ELEC() Command Command Code = 0Eh he ELEC() command is used to place a specific tag in the ELECED state, where it will respond to all commands. tag that is not in the ELECED state will respond only to the INIIE(), CLL16() and L_MKE() commands, all other commands will be ignored. he ELEC() command contains the 8-bit of the tag to be placed in the ELECED state. tag in the ELECED state that receies a ELEC() command that does not match its will automatically reert to the DEELECED state.

9 N LICIN NE CMLEIN() Command Command Code = 0Fh he CMLEIN() command is used to switch the hort ange Contactless Memory in the ELECED state to the DE-CIVED state where it will not decode any further commands. he hort ange Contactless Memory is then locked in the DE-CIVED state until a complete reset is done (tag taken out of the field range). he CMLEIN() command makes it possible to access a new memory by sending a ELEC() command, without haing to remoe the preious memory from the field. he CMLEIN() command does not generate any response from the memory. ll hort ange Contactless Memories that are not in the ELECED state when the CMLEIN() command is issued, ignore the command.

10 N LICIN NE EE INVENY() Command Command Code = 0Ch he EE INVENY() command is used to switch the hort ange Contactless Memory in the ELECED state to the INVENY state. In this way the hort ange Contactless Memory is re-introduce into the anti-collision sequence. his command is useful when two memories with the same 8-bit are in the ELECED state at the same time. Forcing the memories back to the anti-collision sequence allows the reader to generates new CLL16() commands and so to set new random. he EE INVENY() does not generate any response from the memory. ll hort ange Contactless Memories that are not in the ELECED state ignore the EE INVENY() command.

12 N LICIN NE WIE_BLCK() Command Command Code = 09h he WIE_BLCK() command is used to write to a specific hort ange Contactless Memory block. n receiing the command the memory writes the 4-Byte data sent in the command to the addressed block, unless the block is unaailable or write-protected. efer to the corresponding hort ange Contactless Memory datasheet for details of the block behaior when it is write-protected. he data Bytes are transmitted Least ignificant Byte (LByte) first and each Byte is transmitted Least ignificant Bit (LBit) first. he WIE_BLCK equest contains the address Byte used to access the desired hort ange Contactless Memory block. he hort ange Contactless Memory must be placed in the ELECED state by a ELEC() command before it can respond to any WIE_BLCK() command. therwise the hort ange Contactless Memory ignores the command.
