Features

  • Physical Interface and Anticollision compliant to ISO/IEC 14443-2 and -3 Type A
  •  – Operating frequency 13.56 MHz; data rate 106 kbit/s– Contactless transmission of data and supply energy– Anticollision logic: several cards may be operated in the field simultaneously
  • Read and write distance up to 10 cm and more (influenced by external circuitry i.e. reader and inlay design)
  • Short transaction times: Typical ticketing transaction < 100 ms; transaction possible when card is moving
  • Block organization of memory, 16 sectors with fixed 4 blocks of 16 bytes each
  • EEPROM updating time per block less than 4 ms
  • Endurance > 100,000 erase / write cycles (values are temperature dependent)
  • Data retention > 10 years
  • User definable access condition for each memory block
  • SLE66R35I: 4-byte fixed non unique number (FNUID)
  • SLE66R35R: 4-byte fixed reused identity number (r-ID), 4-byte UID previously issued
  • SLE 66R35E7: 7-byte Unique IDentification number (UID). Support of 4-byte Random Number (RND-ID) and 4-byte fixed non-unique number (FNUID) according to ISO/IEC 14443-3 Type A
  • Mutual three-pass authentication between card and reader for basic security
  • – 48-bit key length– 2 keys per sector enabling key management– Transport key at chip delivery
  • Selective memory access secured by authentication and access conditions
  • Suited to multifunctional applications: individual key sets for each EEPROM sector
  • Data encryption for RF channel
  • Dedicated Value Counter
  • Data integrity supported by CRC, Parity Check, etc.
  • On-Chip capacitance 18.3 pF ± 10%
  • ESD protection typical 2 kV
  • Ambient temperature –25°C-70°C for chip
