NXP Semiconductors SL2S5102FUD,003

Overview

SL2S5102FUD,003 from NXP Semiconductors is an ISO/IEC 15693- and ISO/IEC 18000-3-compliant contactless RFID IC for smart labels, featuring 512-bit EEPROM (16 blocks × 4 bytes), 13.56 MHz operation, up to 1.5 m read range, and password-protected privacy, destroy, EAS, and AFI functions - deployed in industrial laundry tracking and asset management systems.

For engineers reviewing the SL2S5102FUD,003 datasheet, SL2S5102FUD,003 pinout, SL2S5102FUD,003 application, or SL2S5102FUD,003 equivalent, this page delivers verified electrical parameters, wafer-level terminal mapping, memory security architecture, and real-world use-case implementation guidance aligned with NXP's ICODE SLIX-L family specifications.

Technical Context

The SL2S5102FUD,003 integrates analog RF interface (13.56 MHz resonant coupling), digital controller with anticollision state machine, and 512-bit EEPROM - all powered contactlessly via inductive coupling without onboard battery. Its RF front-end supports high-speed 53 kbit/s data transfer using ASK modulation and 16-bit CRC error detection.

It implements true ISO/IEC 15693-3 anticollision with inventory and fast inventory page read commands, plus custom NXP commands including ENABLE PRIVACY (B Ah), DESTROY SLIX-L (B9h), and SET PASSWORD (B3h) - all requiring XOR-encoded 32-bit passwords derived from GET RANDOM NUMBER output.

Key Specifications

Pinout & Package

SL2S5102FUD,003 is supplied as a bare die on film frame carrier (120 µm thickness), with four bonding pads: LA and LB (RF antenna inputs), GND (ground), and TEST (test input). No leaded package; requires flip-chip or wire-bond assembly onto custom antenna substrates.

FAQ

What is the primary function of the SL2S5102FUD,003 in an RFID system?

The SL2S5102FUD,003 functions as a contactless, battery-free RFID tag IC compliant with ISO/IEC 15693 and ISO/IEC 18000-3 standards. It stores and transmits identity and user data via inductive coupling at 13.56 MHz, supporting up to 1.5 m read range, anticollision, and password-protected privacy and destroy features - all implemented within its 512-bit EEPROM and analog/digital RF architecture.

How does the SL2S5102FUD,003 differ from the SL2S5002FUD variant?

The SL2S5102FUD,003 differs from SL2S5002FUD primarily in its internal capacitance (Ci = 97 pF vs. 23.5 pF) and die dimensions (520 × 607 µm vs. 520 × 484 µm), enabling longer read range and greater antenna design flexibility. Both share identical command sets, memory organization, and security features - but SL2S5102FUD,003 is optimized for gate-width applications requiring maximum operational distance.

Can the SL2S5102FUD,003 be used in metal-rich environments?

Yes - the SL2S5102FUD,003 can be deployed in metal-rich environments when integrated into purpose-designed metal-mount tags using ferrite shielding or impedance-matching antenna layouts. Its 13.56 MHz frequency and robust analog front-end tolerate moderate electromagnetic interference, and its 97 pF Ci value aids tuning stability on conductive substrates, unlike lower-Ci variants.

What happens when the DESTROY SLIX-L command is executed on the SL2S5102FUD,003?

When the DESTROY SLIX-L command (B9h) is successfully executed with the correct 32-bit Destroy password, the SL2S5102FUD,003 enters a permanent non-responsive state. It ceases all RF communication - no UID, inventory response, or command acknowledgment - and cannot be revived by power cycling, field exposure, or any other means. This irreversible action is confirmed by absence of response to subsequent INVENTORY commands.

Is the TEST pad on the SL2S5102FUD,003 required for normal operation?

No - the TEST pad on the SL2S5102FUD,003 is exclusively for wafer-level functional verification during manufacturing and is not required for end-product operation. In final tag assembly, the TEST pad may be left unconnected, grounded, or omitted entirely depending on the bonding method; its presence does not affect SL2S5102FUD,003 runtime behavior or RF performance.
