Product details
Overview
SL2S5402FUD,003 from NXP Semiconductors is a contactless RFID IC compliant with ISO/IEC 15693 and ISO/IEC 18000-3, designed for smart label applications requiring high security, 2 KB EEPROM, and up to 1.5 m read range. It implements true anticollision, 32-bit password-protected Privacy Mode, Destroy functionality, and EAS/AFI control - deployed in pharmaceutical item-level tagging and library asset tracking.
For engineers reviewing the SL2S5402FUD,003 datasheet, SL2S5402FUD,003 pinout, SL2S5402FUD,003 application, or SL2S5402FUD,003 equivalent, this page delivers verified technical context, memory architecture details, wafer-level terminal mapping, security command behavior, and real-world deployment constraints - all grounded in NXP's Rev. 3.2 product data sheet.
Technical Context
The SL2S5402FUD,003 integrates an analog RF interface (13.56 MHz carrier), digital controller, and 2048-bit EEPROM on a bare die. Its RF interface supports contactless energy harvesting and bidirectional communication at up to 53 kbit/s using 16-bit CRC and framing for integrity.
It executes ISO/IEC 15693-3 anticollision protocols and implements custom NXP commands including ENABLE PRIVACY (BAh), DESTROY SLIX-S (B9h), and 64-bit PASSWORD PROTECTION (BBh). Memory access is enforced via per-page 32-bit passwords (Read, Write, Privacy, Destroy, EAS/AFI) with XOR-based authentication tied to GET RANDOM NUMBER output.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SL2S5302FUD | Same ICODE SLIX-S family, but Ci = 23.5 pF (vs. 97 pF); smaller die (520 × 484 µm) and higher die yield (110,050/wafer vs. 88,225). | Optimized for compact antenna designs with lower capacitance requirements; better suited for thin-label or high-frequency-tuned applications. | Select SL2S5302FUD when antenna geometry constrains inter-pad capacitance or when maximizing wafer utilization is critical. |
| SL2S5502FUD | Successor generation with extended memory (4 KB), enhanced cryptographic acceleration, and improved ESD tolerance (±8 kV HBM). | Targets next-gen secure logistics where larger payload storage and faster authentication are required. | Choose SL2S5502FUD only if migrating to newer NXP platform; SL2S5402FUD,003 remains optimal for cost-sensitive, field-proven 2 KB deployments. |
Compared with SL2S5302FUD and SL2S5502FUD, the SL2S5402FUD,003 provides the optimal balance of proven 1.5 m range, 2 KB memory, and mature 32-bit password security - making it the preferred choice for volume smart label production where antenna capacitance tolerance and supply chain stability are prioritized over incremental feature upgrades.

FAQ
What is the primary function of SL2S5402FUD,003 in an RFID system?
The SL2S5402FUD,003 serves as a contactless, battery-free RFID tag IC operating at 13.56 MHz. It stores and securely transmits data (including a factory-programmed 64-bit UID) via inductive coupling to a reader antenna. Its role is to enable identification, authentication, and data exchange in smart label applications - such as pharmaceutical tracking or library asset management - without requiring onboard power or physical contact.
How does the Privacy Mode work on SL2S5402FUD,003?
Privacy Mode on SL2S5402FUD,003 is activated by the ENABLE PRIVACY command (BAh) using a valid 32-bit Privacy password. Once enabled, the SL2S5402FUD,003 responds only to GET RANDOM NUMBER and SET PASSWORD commands - blocking all other operations including INVENTORY and READ. The mode persists until the correct Privacy password is retransmitted via SET PASSWORD, ensuring compliance with privacy regulations during consumer-facing use.
Can SL2S5402FUD,003 be used with standard ISO/IEC 15693 readers?
Yes, SL2S5402FUD,003 is fully compliant with ISO/IEC 15693-2 and -3, supporting mandatory commands like INVENTORY and STAY QUIET, plus optional commands including READ SINGLE BLOCK and WRITE SINGLE BLOCK. It operates at 13.56 MHz with 53 kbit/s data rate and 16-bit CRC - ensuring seamless interoperability with certified ISO/IEC 15693 readers without firmware modification.
What is the significance of the 97 pF capacitance specification for SL2S5402FUD,003?
The 97 pF typical capacitance between LA and LB terminals defines the intrinsic resonant tank behavior of the SL2S5402FUD,003 bare die. This value directly impacts antenna tuning: designers must match external antenna inductance to achieve resonance at 13.56 MHz. Unlike SL2S5302FUD (23.5 pF), the higher capacitance of SL2S5402FUD,003 favors larger or lower-inductance antenna geometries to maintain optimal read range and power transfer efficiency.
Is SL2S5402FUD,003 pin-compatible with other ICODE SLIX-S variants?
SL2S5402FUD,003 shares identical pinout (LA, LB, GND, TEST) and pad layout with SL2S5302FUD and SL2S5502FUD, confirming mechanical compatibility at the wafer level. However, electrical differences - notably inter-pad capacitance (97 pF vs. 23.5 pF) and die dimensions - require antenna redesign for optimal performance. No PCB layout changes are needed for die mounting, but RF matching networks must be re-validated per variant.
