General Description
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 indi-
vidual memory page. The MAX66120 supports all ISO
15693-defined data rates, modulation indices, subcarri-
er 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.
