NXP ICODE SLIX2

The ICODE SLIX is part of NXP's ICODE family of chips. The ICODE series is older than NXP's NTAG series and has a number of significant differences - particularly a longer 8 byte UID and a longer memory retention specification of 50 years. However, this ICODE SLIX2 variant is newer and contains a large numebr of feature enhancements.

The ICODE chip uses a different standard to the NTAG series - ISO/IEC 15693 instead of ISO/IEC 14443 - the chips can be scanned with current NFC enabled mobile phones in the same way. In 2015, the NFC Forum added the 'Type 5' specification alongside types 1-4, to include the ISO/IEC 15693 specification chips.

Generally, these chips are not commonly used in mobile phone NFC applications. While they are similar in cost to the NTAG series, Seritag generally recommend NTAG unless the additional specified memory retention lifespan is specifically required. The ICODE chips are not available in as many formats as the NTAG chips and are typically made to order.
