Contactless smart-card
Description
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.
