Product data sheet
1 General description
The ICODE SLIX2 IC is the newest member of NXP’s SLIX product family. The chip is
fully backwards compatible to SLIX and offers an increased user memory size, along with
new outstanding features and performance:
• NXP originality signature
• Increased speed for Inventory management
• Increased reading range
• Increased robustness against detuning effects
• 2.5 kbit user memory size
• Flexible user memory segmentation with separate access conditions
• Password protected on chip service cycle counter
1.1 Contactless energy and data transfer
Whenever connected to a very simple and easy-to-produce 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 ICODE SLIX2 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
enables data to be transmitted up to 53 kbit/s.
An intelligent anticollision function enables several tags to operate 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.
1.3 Security and privacy aspects
• Unique IDentifier (UID):
The UID cannot be altered and guarantees the uniqueness of each label.
• Originality signature:
32 byte ECC based originality signature.
• Password protected memory management (Read/Write access):
The user memory can be segmented into two pages and the access rights for read/
write access can be defined for each of them. This ensures that only authorized users
get read/write access to the protected parts of the user memory (anti counterfeiting).
READMULTIPLE BLOCK and (FAST) INVENTORY READ are compatible to ICODE
SLI and ICODE SLIX.
• Password protected Label Destroy:
