ICODE SLIX vs. ICODE SLIX2
These two chips, the ICODE SLIX and the ICODE SLIX2 are from the same ICODE family of chips. They are both manufactured by NXP.
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.
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.
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.
Both these chips have a strong ScanStrength and will work very well with mobile phones.
