ISO 15693-Compliant 64-Bit UID

Unique Identification of a Person or Object

Please check latest availability status for a specific part variant.


The MAX66100 contains a 64-bit unique identifier (UID) and a 13.56MHz ISO 15693 RF interface in a single chip. The UID is revealed during the inventory process. The MAX66100 supports all ISO 15693-defined data rates, modulation indices, subcarrier modes, the selected state, application family identifier (AFI), and data storage format identifier (DSFID). AFI and DSFID are factory programmed with customer-supplied data.
