2k bit Read/Write High Secure

ISO15693 Standard Compliant Device

General Description

The EM4233 is a long range passive CMOS integrated

circuit

intended

for

use

in

applications

requiring

a

contactless read/write memory offering a high and tailored

level of security.

The configurable 2k bit EEPROM memory included in the

chip is organized in 64 words of 32 bits. The high level of

flexibility in the memory management, permits that a

memory word can be read/write protected and/or locked

separately.

This latest generation of EEPROM memory offers data

retention of 60 years enabling solutions for long-term asset

management applications.

The customer data privacy and security is guaranteed by a

powerful and fast crypto engine implemented in the chip

associated with a true random generator and a 96 bit secret

key.

The enhanced on-chip security feature permits a flexible

administration of the memory access rights which makes it

the right solution for advanced theft protection.

Depending on the application requirements, in terms of

security, the user can tailor and adjust the security level by

selecting either a true mutual authentication process, a login

procedure with a 32 bit password or use the chip as a plain

text memory.

The IC supports all the ISO15693 Mandatory commands

and many of the optional commands. Its command set is

completed by unique custom commands which give to the

EM4233 customers a higher degree of differentiation in

terms of security, flexibility and data protection.

Each EM4233 contains in its memory a 64 bit unique serial

number which cannot be altered and guaranties the

uniqueness of each device.
