ICODE SLIX vs ST25TV02KC

Choose ICODE SLIX if you need a compact ISO 15693 solution with 896 bits (112 bytes) of user memory and require privacy protection features. This chip operates at 13.56 MHz and complies with ISO/IEC 15693-2, ISO/IEC 15693-3, and ISO/IEC 18000-3 standards. It organizes memory into 32 blocks of 4 bytes each, with 128 bits reserved for configuration. Security features include a unique non-alterable 64-bit UID, 32-bit password protection for EAS/AFI functions, block-level lock mechanisms for user memory, plus DSFID, AFI, and EAS support. The privacy protection capability makes this suitable for applications where user data confidentiality during inventory scanning is important, such as library systems or document tracking where you want to prevent unauthorized reading. Choose ST25TV02KC if you require double the memory capacity at 2048 bits (256 bytes) organized in 64 blocks of 4 bytes, and need the ability to permanently deactivate tags. This 13.56 MHz chip follows ISO/IEC 15693 and ISO/IEC 18000-3 mode 1 protocols. It provides 32-bit password protection along with AFI, DSFID, and EAS features similar to the ICODE SLIX, but adds a kill command for irreversible tag deactivation. The kill function is valuable in supply chain applications where tags must be permanently disabled at end-of-life or after product sale to prevent tracking concerns. With twice the EEPROM capacity, this chip suits applications needing more data storage per tag, such as pharmaceutical tracking, retail inventory with extended product information, or industrial asset management requiring detailed maintenance records.
