ISO/IEC 14443 Type B-Compliant

1Kb Memory Fob

MAX620

General Description

Features

The MAX66020 combines 1024 bits of user EEPROM, a

64-bit unique identifier (UID), and a 13.56MHz RF inter-

face (ISO/IEC 14443 Type B, Parts 2-4) in a plastic key

fob. The memory is organized as 16 blocks of 8 bytes

plus two more blocks for data and control registers.

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 individual memory page. Memory

access is accomplished 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).

ISO/IEC 14443 functions not supported are chaining,

frame-waiting time extension, and power indication.
