1. General description
The I•CODE SLI-L/I•CODE SLI-L HC IC is a dedicated chip for smart label applications
with the need for a leaner custom-specific command set, smaller memory and/or a
product which takes care of the increasing demand for perfect customer privacy. This IC is
another member of our product family of smart label ICs that fully comply to the ISO
standard ISO/IEC 15693. The IC is also available in high capacitance version for small
label designs.
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-L/I•CODE SLI-L 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. 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.
3. 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.
4. 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.

4. Quick reference data
The data sheet describes the functionality of the smart label ICS I•CODE SLI- L and
I•CODE SLI- L HC. These ICs distinguish between the built in resonance capacitance.
The I•CODE SLI- L HC shows a higher capacitance value than the I•CODE SLI- L.
Therefore within the I•CODE SLI- L HC smaller label designs can be realized.

6. Block diagram
The SL2 ICS50/SL2 ICS51 IC consists of three major blocks:
Analog RF Interface
Digital Controller
EEPROM
The analog part provides stable supply voltage and demodulates data received from the
reader for being processed by the digital part. Further, the modulation transistor of the
analog part transmits data back to the reader.
The digital section includes the state machines, processes the protocol and handles
communication with the EEPROM.

7. Functional description
7.1 Block description
The label requires no internal power supply. Its contactless interface generates the power
supply and the system clock via the resonant circuitry by inductive coupling to the
interrogator. The interface also demodulates data that are transmitted from the
interrogator to the I•CODE Label, and modulates the electromagnetic field for data
transmission from the I•CODE Label to the interrogator.
Data are stored in a non-volatile memory (EEPROM). The EEPROM has a memory
capacity of 512 bit and is organized in 16 blocks consisting of 4 bytes each (1 block =
32 bits). The higher 8 blocks contain user data and the lowest 8 blocks contain the unique
identifier, the write access conditions and special data like AFI and DSFID.
7.2 Memory organization
The 512 bit EEPROM memory is divided into 16 blocks. A block is the smallest access
unit. Each block consists of 4 bytes (1 block = 32 bits). 4 blocks are summed up to 1 page.
Bit 0 in each byte represents the least significant bit (LSB) and bit 7 the most significant bit
(MSB), respectively.
The Memory is divided into 2 parts:
•Configuration Area
–Within this part of the memory all required information are stored like UID, Write
protection, Passwords and so on. Direct access to this memory area is not
possible.
•User Memory
–Within this area the user data are stored. Direct Read/write access to this part of
the memory is possible depending on the related write protection conditions.

7.2.1 Unique identifier
The 64-bit unique identifier (UID) is programmed during the production process according
to ISO/IEC 15693-3 and cannot be changed afterwards.
The numbering of the 64 bits is done according to ISO/IEC 15693-3 starting with the
LSB 1 and ending with the MSB 64. This is in contrast to the general used bit numbering
within a byte (starting with LSB 0).
The TAG type is a part of the UID (bit 41 to 48, after the manufacturer code which is “04h”
for NXP Semiconductors).
The TAG type of the SL2 ICS50/SL2 ICS51 is “03h”

8.1.3.12 EAS Alarm
Command Code = A5h
The EAS Alarm command can be used in the following three configurations:
•Option flag is set to 0:
EAS ID Mask length and EAS ID value shall not be transmitted
If the EAS mode is set the EAS response is returned from the
I•CODE SLI-L/I•CODE SLI-L HC IC. This configuration is compliant to the EAS
command of the I•CODE SLI-L/I•CODE SLI-L HC IC.
•Option flag is set to 1:
Within the command the EAS ID Mask Length has to be transmitted to identify how
many bits of the following EAS ID value are valid (multiple of 8-bit). Only that
I•CODE SLI-L/I•CODE SLI-L HC ICs will respond with the EAS response which have
stored the corresponding data in the EAS ID configuration (selective EAS) and if the
EAS Mode is set.
If the EAS ID Mask length is set to 0, the I•CODE SLI-L/I•CODE SLI-L HC IC will
answer with its EAS ID.

8.2 Long range command
8.2.1 Long Range CMD
Command Code = 40h
The Long Range CMD command is designed to allow the use of the higher limits defined
in the ISO/TR 7003:1990. The bit and byte coding is the same as it is defined in EPC
Specification “13.56 MHz ISM Band Class 1 Radio Frequency (RF) Identification Tag
Interface Specification”.
To reduce the number of pulses the redundancy check is changed from an CRC8
calculation to a XOR of the transmitted parameters (Long Range CMD, Data Selector,
Number of Slots)
•Number of Slots:
–If the Data Selector is transmitted for EAS the label will ignore the received
Number of Slots parameter and will use always one Slot (like EAS Alarm
command, see Section 8.1.3.12 “EAS Alarm”). with EAS. For EAS typically 00h is
used as the value for Number of Slots to reduce the number of transmitted pulses.
–If the Data Selector is transmitted for UID or EPC the label will respond within one
of the transmitted Number of Slots on a pseudo random basis and will calculate a
new slot for a following command.
Labels, which have executed a Destroy EPC command before will not respond to this
command, if the Data Selector for EPC is transmitted.

8.3 Error handling
8.3.1 Transmission errors
According to ISO/IEC 15693 the Label IC will not respond if a transmission error (CRC,
bitcoding, bitcount, wrong framing) is detected and will silently wait for the next correct
received command.
8.3.2 Not supported commands or options
If the received command or option is not supported, the behaviour of the Label IC is
depending on the addressing mechanism.
8.3.2.1 Non addressed mode
The label IC remains silent.
8.3.2.2 Addressed or selected mode
The addressed or selected label IC responds with the error code “0Fh” (error with no
information given or error code is not supported).
If the Inventory flag or the protocol extension flag is set the label IC will not respond if the
command or option is not supported.
8.3.3 Parameter out of range
8.3.3.1 Read commands
If the sum of the first block number and the number of blocks exceeds the total available
number of user blocks, the number of transmitted blocks is less than the requested
number of blocks, which means that the last returned block is the highest available user
block, followed by the 16-bit CRC and the EOF.
8.3.3.2 Write and lock commands
If the address of a block to be written does not exist or a block to be written is locked the
behaviour of the Label IC is depending on the addressing mechanism.
8.3.3.3 Non addressed mode
The Label IC remains silent and aborts the command without writing anything.
8.3.3.4 Addressed or selected mode
The addressed or selected Label IC responds with the error code “0Fh” (error with no
information given or error code is not supported).

8.4 Data integrity
Following mechanisms are implemented in the contactless communication link between
interrogator and label to ensure very reliable data transmission:
•16-bit CRC per block
•Bit count checking
•Bit coding to distinguish between “1”, “0” and no information
•Channel monitoring (protocol sequence and bit stream analysis)
8.5 RF interface
The definition of the RF interface is according to the standard ISO/IEC 15693-2 and
ISO/IEC 15693-3.
