Engineering Brief

The SL2S3003/SL2S3003TT (ICODE 3) is NXP's next-generation 13.56 MHz vicinity label IC fully backward-compatible with SLIX 2, offering ISO/IEC 15693 compliance with extended NFC features and enhanced security. Key improvements include SELFAdjust RF optimization, fast read up to 212 kbit/s, 2.4 kbit user memory with flexible segmentation, 24-bit configurable counter (command-based or NFC auto-increment), ASCII mirror for UID/counter/TagTamper data, and ECC-based 32-byte or 48-byte originality signature. The SL2S3003TT variant adds TagTamper detection with current and stored status (DP/GND pads for tamper wire). Security features include multi-level 32-bit password protection (Read, Write, Privacy, Destroy, EAS/AFI, Config), 64-bit password mode, two privacy modes, persistent quiet mode, and comprehensive lock mechanisms. Delivered as bumped wafer (120 μm, 675×635 μm die, 23.5 pF internal capacitance), it targets anti-counterfeiting, supply chain integrity, NFC consumer engagement, and tamper-evident packaging with operating range up to 1.5 m and 50-year data retention.

Frequently Asked Questions

How much user memory does the NXP ICODE 3 have?

The ICODE 3 provides 2432 bits of user memory organized as 76 blocks of 4 bytes each. Blocks 0-74 (2400 bits) are available for user data, while block 75 contains a 24-bit configurable counter. Additionally, 192 bytes of configuration memory are available.

What is the read speed of the ICODE 3 chip?

The ICODE 3 supports fast read speeds up to 212 kbit/s, significantly faster than earlier ISO 15693 tags. This high data rate enables rapid inventory scanning and improved throughput in supply chain and anti-counterfeiting applications.

Does the ICODE 3 support originality signatures for authentication?

Yes, the ICODE 3 features ECC-based originality signatures using the secp128r1 curve. It supports either 32-byte or 48-byte programmable signatures that enable cryptographic verification of tag authenticity for brand protection and anti-counterfeiting.

What is TagTamper detection on the ICODE 3TT variant?

The SL2S3003TT variant includes TagTamper detection via dedicated DP/GND pads for connecting a tamper wire or loop. The chip stores both current and historical tamper status, enabling detection of package opening or seal breach events for tamper-evident applications.

Is the ICODE 3 backward compatible with ICODE SLIX 2?

Yes, the ICODE 3 (SL2S3003) is fully backward-compatible with the ICODE SLIX 2, maintaining ISO 15693 compliance while adding extended features like faster read speeds, ECC signatures, TagTamper support, and enhanced password protection.

What password protection options does the ICODE 3 support?

The ICODE 3 offers comprehensive password protection including 32-bit passwords for Read, Write, Privacy, Destroy, EAS/AFI, and Configuration operations, plus a 64-bit password mode. It supports two privacy modes and includes lock mechanisms at block and page levels for granular access control.
