ISO/IEC 14443 Type B-Compliant

64-Bit UID

_______________________________________________________________________________________

Detailed Description

The MAX66000 combines a 64-bit 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

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-

er must support a frame size of at least 19 bytes. The

data rate can be as high as 847.5kbps. The MAX66000

supports AFI and CID. ISO 14443 functions not sup-

ported are chaining, frame-waiting time extension, and

power indication. Applications of the MAX66000

include driver identification (fleet application), access

control, and asset tracking.

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

14443 Type B-compliant access protocol. The master

must first apply network function commands to put the

MAX66000 into the ACTIVE state to read the UID or

system information. The protocol required for these net-

work function commands is described in the

Network

Function Commands section. Once the MAX66000 is in

the ACTIVE state, the master can use the memory func-

tion commands. Upon completion of such a command,

the MAX66000 returns to the ACTIVE state and the

master can issue another memory function command or

deselect the device, which returns it to the HALT state.

The protocol for these commands is described in the

Memory Commands section. All data is read and writ-

ten least significant bit (LSb) first, starting with the least

significant byte (LSB).

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: System requirement.

which the MAX66000’s internal power-on reset signal is deasserted and the device is ready to receive a command frame.
