ISO/IEC 14443 Type B-Compliant

Secure Memory

MAX640

General Description

Features

The MAX66040 combines 1024 bits of user EEPROM

with secure hash algorithm (SHA-1) challenge-and-

response authentication (ISO/IEC 10118-3 SHA-1), a

64-bit unique identifier (UID), one 64-bit secret, and a

13.56MHz RF interface (ISO/IEC 14443 Type B, Parts 2-

4) in a single chip. The memory is organized as 16

blocks of 8 bytes plus three more blocks, one for the

secret and two for data and control registers. Except for

the secret, each block has a user-readable write-cycle

counter. Four adjacent user EEPROM blocks form a

memory page (pages 0 to 3). The integrated SHA-1

engine provides a message authentication code (MAC)

using data from the EEPROM of the device and the 64-

bit secret to guarantee secure, symmetric authentica-

tion for both reading and writing to the device. Memory

protection features are write protection and EPROM

emulation, which the user can set for each individual

memory page. Page 3 can also be read-protected for

enhanced authentication strength. 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 26

bytes. The device supports an application family identi-

fier (AFI) and a card identifier (CID). ISO/IEC 14443

functions not supported are chaining, frame-waiting

time extension, and power indication.
