MAX66000 19-5528 Rev 0 1/11 ISO/IEC 14443 Type B-Compliant 64-Bit UID General Description Features The MAX66000 combines a 64-bit unique identifier Fully Compliant ISO/IEC 14443 (Parts 2-4) Type B (UID) and a 13.56MHz RF interface (ISO/IEC 14443 Interface Type B, Parts 2-4) in a single chip. The UID can be 13.56MHz 7kHz Carrier Frequency read through the block transmission protocol (ISO/IEC 64-Bit UID 14443-4), where requests and responses are exchanged through I-blocks once a device is in the Supports AFI and CID Function ACTIVE state. The data rate can be as high as Write: 10% ASK Modulation at 105.9kbps, 847.5kbps. The reader must support a frame size of 19 211.9kbps, 423.75kbps, or 847.5kbps bytes. The device supports an application family identi- Read: Load Modulation Using BPSK Modulated fier (AFI) and a card identifier (CID).

Detailed Description The MAX66000 combines a 64-bit UID and a INTERNALSUPPLY 13.56MHz RF interface (ISO/IEC 14443 Type B, Parts 2-4) in a single chip. The UID can be read through the VOLTAGE REGULATOR ISO/IEC 14443-4 block transmission protocol, where requests and responses are exchanged through I- blocks once a device is in the ACTIVE state. The read- RF er must support a frame size of at least 19 bytes. The FRONT- data rate can be as high as 847.5kbps. The MAX66000 ISO 14443 END supports AFI and CID. ISO 14443 functions not sup- FRAME UID, AFI, ported are chaining, frame-waiting time extension, and FORMATTING APPLICATION DATA power indication. Applications of the MAX66000 AND DATA FIELD f c include driver identification (fleet application), access ERROR DETECTION control, and asset tracking. MODULATION Overview Figure 1 shows the relationships between the major control and memory sections of the MAX66000. Figure 2 shows the hierarchical structure of the ISO/IEC Figure 1. Block Diagram 14443 Type B-compliant access protocol. The master must first apply network function commands to put the the MAX66000 returns to the ACTIVE state and the MAX66000 into the ACTIVE state to read the UID or master can issue another memory function command or system information. The protocol required for these net- deselect the device, which returns it to the HALT state. work function commands is described in the Network The protocol for these commands is described in the Function Commands section. Once the MAX66000 is in Memory Commands section. All data is read and writ- the ACTIVE state, the master can use the memory func- ten least significant bit (LSb) first, starting with the least tion commands. Upon completion of such a command, significant byte (LSB). 2 MAX66000
