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.
