Engineering Brief

The ICODE ILT (SL2S1402/1502/1602) is a passive HF RFID chip supporting ISO 18000-3 mode 3 and EPC Class-1 HF standards at 13.56 MHz. It offers up to 240-bit EPC memory, a 96-bit TID with 48-bit unique serial number, and extremely low power operation (minimum 40 μW input power) for long read ranges. Key features include advanced anti-collision (up to 800 tags/s), fast initialization for EPC writing, variable data rates (forward link 25-100 kbit/s, return link 53-848 kbit/s), Electronic Article Surveillance (EAS) functionality, and memory protection via 32-bit access/kill passwords. Available as bumped wafer (75 μm or 120 μm) or XSON3 package, with integrated capacitor variants (0 pF, 23.5 pF, 97 pF) for flexible antenna matching in supply chain, laundry, healthcare, and document tracking applications.

Frequently Asked Questions

What is the read range of the NXP ICODE ILT chip?

The ICODE ILT supports extremely long read ranges due to its low minimum input power requirement of 40 μW. Actual read range depends on antenna design, reader power, and environmental factors, but it is optimized for industrial applications requiring extended detection distances.

How much memory does the ICODE ILT have?

The ICODE ILT features 240-bit EPC memory for product identification, a 96-bit TID (including a 48-bit unique serial number), and 64 bits of reserved memory (32-bit access password and 32-bit kill password).

What protocols does the ICODE ILT support?

The chip supports ISO 18000-3 mode 3 and EPC Class-1 HF RFID standards, operating at 13.56 MHz in the ISM band. It is compatible with standard HF RFID readers supporting these protocols.

Does the ICODE ILT have anti-collision capability?

Yes, the ICODE ILT features advanced anti-collision algorithms capable of inventorying up to 800 tags per second, making it suitable for high-density environments like laundry facilities and supply chain operations.

What security features does the ICODE ILT offer?

The chip includes 32-bit access and kill passwords for memory protection, configurable memory lock functionality, and a recommissioning feature that allows tags to be reactivated after being killed. It also supports Electronic Article Surveillance (EAS) functionality.

What package options are available for the ICODE ILT?

The ICODE ILT is available as bumped wafer (75 μm or 120 μm thickness) for direct antenna bonding, or in XSON3 package. Integrated capacitor variants are offered in 0 pF, 23.5 pF, and 97 pF values for flexible antenna tuning.
