ISO/IEC 14443 Type B-Compliant 64-Bit UID

Unique Identification of a Person or Object

Please check latest availability status for a specific part variant.


The MAX66000 combines a 64-bit unique identifier (UID) and a 13.56MHz RF interface (ISO/IEC 14443 Type B, Parts 2-4) in a single chip. The UID can be read through the block transmission protocol (ISO/IEC 14443-4), where requests and responses are exchanged through I-blocks once a device is in the ACTIVE state. The data rate can be as high as 847.5kbps. The reader must support a frame size of 19 bytes. The device supports an application family identifier (AFI) and a card identifier (CID). AFI and the application data field can be factory programmed with customer-supplied data. ISO/IEC 14443 functions not supported are chaining, frame-waiting time extension, and power indication.
