1 General description
ICODE 3 is the next generation of the ICODE product family of 13.56 MHz based vicinity label ICs. ICODE 3
overcomes some known challenges in RFID solution design and industrialization process. ICODE 3 combines
native NFC features with the increased read range of ISO/IEC 15693-based tags. SL2S3003TT is the ICODE 3
version with TagTamper feature, and SL2S3003 is the version without TagTamper.
Fully backward-compatible with SLIX 2, the ICODE 3 supports improved performance and new features:
• SELFAdjust
• Fast read with up to 212 kbit/s
• Configurable 24-bit counter
• ASCII mirror feature option
• One-shot read-only memory lock
• Extra configuration memory with optional password protection
• Programmable originality signature with 32 bytes or 48 bytes
• 2.4 kbit user memory size
• Flexible user memory segmentation with separate access conditions
• TagTamper feature with current and stored status (only SL2S3003TT)

2 Features and benefits
2.1 ICODE 3 RF interface (ISO/IEC 15693)
• SELFAdjust feature for optimal RF performance
The ICODE 3 has an automatic mechanism implemented which adjusts the RF performance to the optimum in
the operated environment. The adjustment is performed at start-up.
• Contactless transmission of data and power (no battery needed)
• Operating distance of up to 1.5 m (depending on the antenna geometry)
• Operating frequency of 13.56 MHz (ISM, worldwide license freely available)
• Fast data transfer of up to 212 kbit/s
• High data integrity: 16-bit CRC, framing
• True anticollision feature
• Persistent quiet mode to enable faster inventory speed
• Write distance equal to read distance
2.2 EEPROM
• 2432 bits of user memory organized in 76 blocks of 4 bytes each. The last block is reserved for the 24-bit
counter feature.
• 50 years of data retention
• Write endurance of 100000 cycles
2.3 Data protection
• 8-byte unique identifier
• 32-byte or 48-byte programmable originality signature
• Lock mechanism for each user memory block (write protection), and lock protection pointer for fast locking
• Lock mechanism for DSFID, AFI, EAS
• Password (32-bit) protected memory management for Read access
• Password (32-bit) protected memory management for Write access
• Password (32-bit) protected label Destroy
• Password (32-bit) protected privacy mode
• Password (32-bit) protected EAS and AFI functionality
• Password (32-bit) protected memory configuration
• 24-bit counter (NFC counter, or command-based counter with optional password protection)
• Programmable open TagTamper message only visible after the detection of the first open event

3 Applications
• Product identification
• Product tracking and tracing
• Counterfeit and tamper protection
• Inventory management
• Smart-device consumable system communication
• Augmented mobile interaction
