Contactless, secure EEPROM offers 320 bytes of memory, organized into up to 32 pages. Its contactless interface and 2-way mutual authentication algorithm, powered by a robust 64-bit key and 32-bit MAC, ensures secure data transactions. Data integrity is safeguarded by 16-bit CRC, even before authentication. High on-chip capacitance (97 pF ± 5%) allows smaller tag antenna designs. It also features value counters for a reliable data management.
