ISO 15693-Compliant 1Kb Memory Fob

All versions are being discontinued and are subject to Last Time Buy, after which new orders can not be placed.

The MAX66120 combines 1024 bits of user EEPROM, a 64-bit unique identifier (UID), and a 13.56MHz ISO 15693 RF interface in a plastic key fob. The memory is organized as 16 blocks of 8 bytes plus two more blocks for data and control registers. Each block has a user-readable write-cycle counter. Four adjacent user EEPROM blocks form a memory page (pages 0 to 3). Memory protection features are write protection and EPROM emulation, which the user can set for each individual memory page. The MAX66120 supports all ISO 15693-defined data rates, modulation indices, subcarrier modes, the selected state, application family identifier (AFI), data storage format identifier (DSFID), and the Option_flag bit for read operations. Memory write access is accomplished through standard ISO 15693 memory and control function commands.
