General description

The I•CODE SLI-S/I•CODE SLI-S HC IC is a dedicated chip for smart label applications

with the need for a higher security level, larger memory and/or a product which takes care

of the increasing demand for perfect customer privacy. This IC is the second member of a

product family of smart label ICs based on the ISO standard ISO/IEC 15693 as well as on

EPC Global compliant commands.

The I•CODE system offers the possibility of operating more than one label simultaneously

in the field of the reader antenna (Anticollision). It is designed for long range applications

with a special command for the use under the European regulations.

1.1 Anticollision

An intelligent anticollision function allows to operate more than one tag in the field

simultaneously. The anticollision algorithm selects each tag individually and ensures that

the execution of a transaction with a selected tag is performed correctly without data

corruption resulting from other tags in the field.

1.2 Contactless energy and data transfer

Whenever connected to a very simple and cheap type of antenna (as a result of the

13.56 MHz carrier frequency) made out of a few windings printed, winded, etched or

punched coil the I•CODE SLI-S/I•CODE SLI-S HC IC can be operated without line of sight

up to a distance of 1.5 m (gate width). No battery is needed. When the smart label is

positioned in the field of an interrogator antenna, the high speed RF communication

interface allows to transmit data with up to 53 kbit/s.

1.3 Security and privacy aspects

1. Unique Identifier (UID)

The UID can not be altered and guarantees the uniqueness of each label.

2. OTP Memory for EPC Code

The memory for the EPC Code is an one time programmable memory, which ensures

that the data can not be changed after user programming.

3. Password protected memory management (Read/Write access)

Pages (1 page = 4 blocks of 4 byte each) can be protected with a password, which

ensures that only authorized users get read/write access to the protected parts of the

user memory (anti counterfeiting).

4. Password protected Label Destroy

With the 32-bit destroy password an addressed label can be destroyed with the

Destroy command. That status is irreversible and the label will never respond to any

command again.

5. Password protected Privacy Mode

With the 32-bit Privacy password a label can be set to the Privacy mode with the Set

to Privacy Mode command. In that mode the label will not respond to any command

except of the command Get Random Number till it receives again the right Privacy

password. That mode is especially designed to meet the increasing demand to take

care of the customers privacy.

6. Password protected EAS Functionality

With the 32-bit EAS password the addressed label can be set in a mode that the

commands Set EAS and Reset EAS are only executed by the label if the right EAS

password is transmitted to the label within the mentioned commands.
