ICODE SLIX vs. Ultralight EV1 (48 Byte)
These two chips, the ICODE SLIX and the Ultralight EV1 (48 Byte) are from different NFC chip families. The ICODE SLIX, manufactured by NXP belonging to the ICODE family, and the Ultralight EV1 (48 Byte), also 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 NXP MIFARE Ultralight® EV1 is a updated version of the very popular Ultralight chip from NXP. The original Ultralight chip dates back to 2001 and the product has been used for ticketing the world over. It’s a very simple, reliable and cost effective product. Unfortunately, there’s probably almost as many non-genuine MIFARE Ultralight chips as genuine ones. The EV1 update added an originality check feature to help counteract this.
There are two variants of the Ultralight EV1 with two memory capacities. The smaller chip has 48 bytes of usable memory (similar to the NTAG210 and NTAG210micro) and the larger has 128 bytes (similar to the NTAG212).
Both these chips have a strong ScanStrength and will work very well with mobile phones.
