Infineon SRF55V02P Contactless Card

  Intelligent 2.5 Kbit EEPROM with Contactless Interface (ISO/IEC 15693 and ISO/IEC 18000-3 mode 1) Features Contactless Interface • Physical Interface and Anticollision compliant to ISO/IEC 15693 and ISO/IEC 18000-3 mode 1 — contactless transmission of data and supply energy — carrier frequency: 13.56 MHz — data rate up to 26 kbit/s — anticollision with identification of up to 30 tags/sec — read / write distance up to 150 cm depending on reader antenna configuration 2.5 Kbit EEPROM • ISO mode – block organization of memory — up to 56 blocks of user memory (block size 4 bytes) • Custom mode – page organization of memory — up to 32 pages of user memory (page size 8 bytes) • Unique chip identification number (UID) • EEPROM programming time per block/page < 4 ms • EEPROM endurance > 100,000 erase/write cycles1) • Data retention > 10 years1) Value Counters: up to 65536 (value range from 0 to 216-1) — each page in the User Area is configurable as a Value Counter — support of Anti-Tearing Electrical characteristics • ESD protection minimum 2 kV • Ambient temperature –25 … +70°C (for the chip) The my-d® products are designed to meet increased demands for security and design flexibility. The family of contactless memory my-d® supplies the user with different memory sizes and incorporates security features to enable considerable flexibility in the application design. The functional architecture, meaning the memory organisation and authentication of my-d® products is the same for both, my-d® proximity (ISO/IEC 14443) and my-d® vicinity (ISO/IEC 18000-3 mode 1 or ISO/IEC 15693). This eases the system design and allows simple adaptation between applications. All my-d® products are available in plain mode with open memory access and in secure mode with memory access controlled by authentication procedures. Flexible controls within the my-d ICs start with plain mode operation and individual page locking for more complex applications various settings in secure mode can be set for multi user / multi application configurations. In secure mode a cryptographic algorithm based on 64-bit key is available. Mutual authentication, message authentication codes (MAC) and customized access conditions protect the memory against unauthorized access. Configurable value counters featuring anti-tearing functionality are suitable for value token applications, such as limited use transportation tickets. Architectural interoperability of all my-d® products enables an easy migration from simple to more demanding applications. In addition, the my-d® light (ISO/IEC 18000-3 mode 1 or ISO/IEC 15693) is part of the my-d® family. Its optimized command set and memory expands the range of applications to cost sensitive segments.
