GENERAL DESCRIPTION dedicated chip intelligent label like supply chain management well baggage parcel identification airline business mail services. This first member product family smart label based standard 15693. system offers possibility operating labels simultaneously field reader antenna (Anticollision). designed long range applications.
Contactless Energy Data Transfer Whenever connected very simple cheap type antenna result 13.56 carrier frequency) made windings printed, winded, etched punched coil operated without line sight distance (gate width). battery needed. When smart label positioned field interrogator antenna, high speed communication interface allows transmit data with kbit/s.
Anticollision intelligent anticollision function allows operate more than field simultaneously. anticollision algorithm selects each individually ensures that execution transaction with selected performed correctly without data corruption resulting from other tags field.
Security Unique Identifier, which altered, guarantee uniqueness each label

Memory Organisation EEPROM user memory divided into blocks. block smallest access unit. Each block consists bytes block bits). each byte represents least significant (LSB) most significant (MSB), respectively. contents blocks defined delivery. blocks addressed read write commands. 3.2.1 CONFIGURATION DELIVERED delivered with following configuration Philips: Unique Identifier unique read only Write Access Conditions allow change blocks (with exception both blocks). Status mode defined supported defined DSFID supported defined User Data memory defined

reads requested block(s) sends back their value response. Additionally bytes UID, which parts mask slot number case slots, returned. Instead padding with zeros next byte boundary corresponding bits returned. mechanism timing Inventory read command perform same Inventory command which described Clause ISO/IEC 15693-3.
Note: number bits re-transmitted calculated follows:
