1 DESCRIPTION

The UCODE HSL IC (UCODE High frequency Smart Label) is a dedicated chip for passive, intelligent tags and

labels, especially for supply chain management and logistics applications in the US, where operating distances

of several meters can be realized. Further, the UCODE HSL technology platform is also designed for operation

under European regulations.

This integrated circuit is the first member of a product family of smart label ICs targeted to be compliant with

the future ISO standards 18000-4 and 18000-6 for item management.

The UCODE system offers the possibility of operating labels simultaneously in the field of the reader antenna

(Anticollision, Collision Arbitration).

The UCODE HSL family of ICs is especially designed for long range applications.

The tag requires no internal power supply. Its contactless interface generates the power supply via the antenna

circuit by propagative energy transmission from the interrogator (read/write device), while the system clock is

generated by an on-board oscillator. The contactless interface demodulates data transmitted from the

interrogator to the UCODE HSL based tag, and further modulates the electromagnetic field provided by the

interrogator for data transmission from the UCODE HSL based tag to the interrogator.

1.1 Contactless Energy and Data Transfer

Whenever connected to a dedicated antenna for the targeted frequency range, the UCODE HSL can be

operated without the line of sight and without the need of a battery on the tag. When the smart label or tag is

within the operating range of the interrogator (read/write device), the high speed radio frequency communication

interface allows to transmit data in both directions.

The maximum typical operating distances depend on local regulations and the used frequency band.

2) Proposal for future CEPT/ETSI regulations

3) FCC regulations, Part 15 Section 247

4) In many other countries regulations either similar to FCC or CEPT/ETSI may apply.

6) FCC regulations Part 15 Section 247

7) In many other countries regulations either similar to FCC or CEPT/ETSI apply.

8) These distances are typical values for general tags and labels. A special tag antenna design could achieve

higher values.

Practical useable read distance values may be notable lower, strongly depending on application set-up,

damping by environment materials and the quality of the matching between tag antenna and chip impedance.

1.2 Collision Arbitration, Anticollision

An intelligent collision arbitration function allows operating more than one label in the filed simultaneously. The

aniticollision 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.

1.3 Data Integrity

The following mechanisms are implemented in the contactless communication link between the interrogator and

the tag ensure very reliable data transmission:

•

16 bit CRC

Bit count checking

Bit coding to distinguish between “1”, “0” and no information

Channel monitoring (protocol sequence and bit stream analysis)

1.4 Air Interface Standards

The SL3ICS30 is fully supporting standardization on air interfaces. The SL3ICS30 is targeted to be compliant

with the following air interfaces:

•

ISO/IEC 18000-4 – Information Technology - Radio Frequency Identification (RFID) for Item Management –

Part 4: Parameters for Air Interface Communications at 2.45 GHz

ISO/IEC 18000-6 – Information Technology - Radio Frequency Identification (RFID) for Item Management –

Part 6: Parameters for Air Interface Communications at 860 - 930 MHz

ANSI/INCITS 256-2001 – Radio Frequency Identification (RFID) Part 3 - 2.45 GHz

ANSI/INCITS 256-2001 – Radio Frequency Identification (RFID) Part 4 - UHF

1.5 Application Standards

The SL3ICS30 is also fully supporting application standardization. The SL3ICS30 is targeted to be compliant

with the following application standards:

•

MH10.8.4 – Radio Frequency Identification for Returnable Containers and Cable Reels

AIAG B-11 – Automotive Tire and Wheel Label Radio Frequency (RFID) Identification Standard

EAN.UCC GTAG™ – Radio Frequency Identification (RFID) Performance Standards Initiative

ISO 18185 – Freight Containers -Radio-frequency communication protocol for electronic seal

1.7 Memory Organization

The 2048 bit EEPROM memory is grouped in UID memory, user memory and lock information. A byte is the

smallest access unit. All bytes can be addressed by read and write commands.

1.7.1 Write Access Conditions

Each byte in the user memory can be write protected individually. Write protected blocks can never be written

again.

1.7.2 Serial Number

Serial numbers, which can not be altered, guarantee the uniqueness of each label.

1.7.3 Configuration of delivered ICs

UCODE HSL ICs are delivered with the following configuration from Philips:

•

Serial number is unique and read only

Write Access conditions allow changing all bytes except those containing the serial number

User data memory is not defined
