BL75R06SM 8K-bit EEPROM Contactless smart card chip Description BL75R06SM Contactless smart card chip consists of the RF-Interface, the Digital Control Unit and the 8 Kbit EEPROM. Operating distance is up to 10cm(depending on antenna geometry). The communication layer complies to parts 2 and 3 of the ISO/IEC 14443A standard. The chip supports PHILIPS’s MIFARE card reader. It can be used for ticketing systems in public transport and comparable applications. Features RF interface : ISO/IEC 14443 Type A Operating frequency : 13.56 MHz Fast data transfer : 106 kbit/s Memory size : 8 Kbit No battery needed : contactless transmission of data and supply energy Anti-collision : allows to operate more than one card in the field simultaneously Operating distance : Up to 100mm ( depending on antenna geometry) Transaction possible with moving card Half-duplex communication protocol using handshake Following mechanisms are implemented in the contactless communication link between RWD and card to ensure very reliable data transmission : --- Anti-collision mechanism --- 16 bits CRC pre block --- Parity bits for each byte --- Bit count checking --- Bit coding to distinguish between “1”,”0”,and no information --- Channel monitoring (protocol sequence and bit stream analysis) Offer multi-application functionality --- 8 K-bit EEPROM(16 Sectors×4 Blocks×16 Bytes×8 Bit) --- Organised in securely separated 16 sectors supporting multi-application use --- each sector consists of 4 blocks --- A block is the smallest part to be addressed and consists of 16 bytes --- Individual set of two keys per sector(per application) --- User definable access conditions for each memory block --- Arithmetic : increment and decrement Data retention of 10 years Write endurance 100,000 cycles Typical operation parameter : --- Anti-collision time : 3.0ms + 1.0ms --- Authentication : 2.0ms --- Read block : 2.5ms --- Write block : 6.0ms --- Transfer : 4.5ms Typical ticketing transaction : < 100ms Identification of card + 6 Blocks read (768 bit, 2 Sector Authentication) + 2 Blocks write(256bit) with Backup http://www.belling.com.cn -1Total 9 Pages 8/16/2006 BL75R06SM 8K-bit EEPROM Contactless smart card chip Functional Description Block Diagram BL75R06SM Contactless smart card IC consists of the RF-Interface, the Digital Control Unit and the 8 Kbit EEPROM, as show in the below figure: RF Interface Rectifier Voltage Regulator Modulator/ Demodulator Power On Reset Digital Control Unit Coding and Decoding Unit Anti-collision Communication Unit Arithmetic Unit Clock Control Crypto Unit EEPROM EEPROM EEPROM Interface Memory Control Unit Authentication & Access Control Transaction Sequence Diagram http://www.belling.com.cn -2Total 9 Pages 8/16/2006 BL75R06SM 8K-bit EEPROM Contactless smart card chip Commands The BL75R06SM RFID ICs support the following commands: 1 Request Standard / All After Power On Reset (POR) of a card it can answer to a request command - sent by the RWD to all cards in the antenna field - by sending the answer to request code (ATQA according to ISO/IEC 14443A). 2 Anticollision Loop In the anticollision loop the serial number of a card is read. If there are several cards in the operating range of the RWD, they can be distinguished by their unique serial numbers and one can be selected (select card) for further transactions. The unselected cards return to the standby mode and wait for a new request command. 3 Select Card With the select card command the RWD selects one individual card for authentication and memory related operations. The card returns the Answer To Select(ATS) code (= 08h), which determines the type of the selected card. 4 3 Pass Authentication After selection of a card the RWD specifies the memory location of the following memory access and uses the corresponding key for the 3 pass authentication procedure. After a successful authentication all memory operations are encrypted. 5 Memory Operations After authentication any of the following operations may be performed: Read block Write block Decrement: Decrements the contents of a block and stores the result in a temporary internal data-register Increment: Increments the contents of a block and stores the result in the data-register Restore: Moves the contents of a block into the data-register Transfer: Writes the contents of the temporary internal data-register to a value block Data Integrity Following mechanisms are implemented in the contactless communication link between RWD and card to ensure very reliable data transmission: • 16 bits CRC per block • Parity bits for each byte Security To provide a very high security level a three pass authentication according to ISO 9798-2 is used. Three Pass Authentication Sequence a. The RWD specifies the sector to be accessed and chooses key A or B. b. The card reads the secret key and the access conditions from the sector trailer. Then the car.
