Intelligent 1 Kbyte Memory Chip

with Interface for Contactless Transmission, Security Logic

Features

1 Kbyte EEPROM

• Organised in 16 sectors with 4 blocks of 16 byte each

• User definable access condition for each memory block

• Unique chip identification number

• Read and write distance up to 10 cm and more (influenced by external circuitry i.e. reader-

antenna configuration)

• Physical Interface and Anticollision complying to ISO/IEC 14443, part 2-3

– Contactless transmission of data and supply energy

– Anticollision logic: Several cards may be operated in the field simultaneously

– Operating frequency 13.56 MHz

– Data rate transfer 106 Kbit/s

• Short transaction times: Typical ticketing transaction < 100 ms (including backup); transaction

possible with moving card

Security Features

• Mutual three pass authentication between card and reader

• Data encryption for RF channel

• Data integrity supported by several mechanisms: anticollision, 16 bit CRC, parity check, bit

count checking and channel monitoring

• Suited for multifunctional applications by individual key sets for each EEPROM sector

• Access protection to EEPROM by transport key on chip delivery

Sophisticated electrical characteristics

• EEPROM programming time 5 ms

• ESD protection typical 6 kV

• Ambient temperature – 25 … +70°C
