Overview

SL2S2002FUD,003 from NXP Semiconductors is a contactless RFID IC compliant with ISO/IEC 15693 and ISO/IEC 18000-3 standards, designed for intelligent label applications including pharmaceutical item-level tagging, library asset tracking, and anti-counterfeiting. It operates at 13.56 MHz, delivers up to 53 kbit/s data transfer, supports true anticollision, and integrates 1024-bit EEPROM with 50-year data retention and 100,000 write cycles.

For engineers reviewing the SL2S2002FUD,003 datasheet, SL2S2002FUD,003 pinout, SL2S2002FUD,003 application, or SL2S2002FUD,003 equivalent, this page provides verified technical context, wafer-level pin mapping, memory architecture details, security features (UID, password-protected EAS/AFI), and real-world deployment guidance for high-reliability smart labeling systems.

Technical Context

The SL2S2002FUD,003 implements a fully integrated analog RF interface with resonant coupling, on-chip voltage regulation, and demodulation/modulation circuitry enabling battery-free operation via inductive coupling to reader antennas. Its digital controller executes ISO/IEC 15693-3 protocol stack-including mandatory INVENTORY and STAY QUIET commands-plus custom NXP commands like GET RANDOM NUMBER and SET PASSWORD for secure access control.

Memory is organized into 32 blocks of 4 bytes each (1024 bits total), split between protected configuration area (UID, AFI, DSFID, EAS) and user-accessible memory (896 bits). The IC supports fast anticollision read, write distance equal to read distance (up to 1.5 m), and dual-mode EAS/AFI password protection enabled via A6h command with Option flag selection.

Key Specifications

Pinout & Package

SL2S2002FUD,003 is supplied as a bare die on film frame carrier (wafer format), 120 μm thick, with four bonding pads: LA and LB (antenna RF inputs), GND (ground), and TEST (test input). No leadframe or molded package is present; integration requires flip-chip or wire-bond assembly onto antenna substrates.

FAQ

What is the primary function of SL2S2002FUD,003 in an RFID system?

The SL2S2002FUD,003 functions as a contactless ISO/IEC 15693-compliant RFID transponder IC, providing secure, battery-free identification and data storage via inductive coupling at 13.56 MHz. It serves as the core silicon element in smart labels-handling RF energy harvesting, protocol execution, UID transmission, and encrypted memory access. Its design enables reliable operation in demanding environments such as pharmaceutical packaging and library circulation systems.

Does SL2S2002FUD,003 require an external power source?

No, SL2S2002FUD,003 operates entirely without an external power source. It derives operating power from the electromagnetic field generated by an ISO/IEC 15693-compliant reader antenna through inductive coupling between its LA and LB terminals and the external antenna coil. This enables maintenance-free, decades-long operation in passive smart labels-critical for applications like medical device traceability and archival document tagging.

How is memory organized in SL2S2002FUD,003?

SL2S2002FUD,003 contains 1024 bits of EEPROM organized into 32 blocks of 4 bytes each. Blocks 0–27 constitute user memory (896 bits), directly readable/writable subject to per-block lock status. Blocks 28–31 hold configuration data (UID, AFI, DSFID, EAS) and are inaccessible via standard read/write commands-only modifiable through dedicated ISO/IEC 15693-3 commands like WRITE AFI or LOCK DSFID, with optional password enforcement.

What security mechanisms does SL2S2002FUD,003 support?

SL2S2002FUD,003 supports multiple hardware-enforced security layers: a factory-programmed, immutable 64-bit UID; per-block write locks for user memory; password-protected EAS and AFI functions (32-bit XOR-authenticated); and lockable configuration fields (DSFID, AFI, EAS). These features prevent unauthorized cloning, tampering, or deactivation-making SL2S2002FUD,003 suitable for anti-counterfeiting and regulated supply chain applications.

Can SL2S2002FUD,003 be used with standard HF RFID readers?

Yes, SL2S2002FUD,003 is fully compatible with any ISO/IEC 15693-2/-3-compliant HF RFID reader, including those from Impinj, ThingMagic, and Nordic Semiconductor. It supports all mandatory commands (INVENTORY, STAY QUIET) and optional features (READ/WRITE MULTIPLE BLOCKS, FAST INVENTORY READ), ensuring seamless integration into existing infrastructure without firmware modification or proprietary drivers.
