NXP Semiconductors SL2S2002FTB,115

Overview

SL2S2002FTB,115 from NXP Semiconductors is an ISO/IEC 15693-compliant contactless RFID IC for intelligent label applications, featuring 1024-bit EEPROM (32 blocks × 4 bytes), 13.56 MHz operation, up to 1.5 m read/write distance, and password-protected EAS/AFI functionality. It serves as a secure, battery-free tag IC in pharmaceutical item-level tagging and library asset tracking.

For engineers reviewing the SL2S2002FTB,115 datasheet, SL2S2002FTB,115 pinout, SL2S2002FTB,115 application, or SL2S2002FTB,115 equivalent, key selection criteria include its XSON3 (SOT1122) 3-terminal RF interface, UID uniqueness guarantee, 50-year data retention, 100,000 write endurance, and support for fast anticollision read and INVENTORY READ custom commands.

Technical Context

The SL2S2002FTB,115 implements a fully integrated analog RF interface with resonant demodulation and load modulation, enabling passive operation via inductive coupling at 13.56 MHz. Its digital controller executes ISO/IEC 15693-3 anticollision, supports mandatory and optional commands (e.g., READ/WRITE SINGLE/MULTIPLE BLOCK, LOCK BLOCK), and manages EEPROM access with per-block write protection.

Security is enforced through a factory-programmed 64-bit immutable UID, 32-bit EAS/AFI password (transmitted via XOR with random number), and lock mechanisms for DSFID, AFI, EAS, and user memory blocks. The IC operates without internal power-energy and clock are derived entirely from the reader's RF field.

FAQ

What is the antenna interface configuration for SL2S2002FTB,115?

The SL2S2002FTB,115 uses a two-terminal RF interface: LA and LB connect directly to opposite ends of an external LC resonant antenna coil. No external capacitor is needed-the IC's internal capacitance between LA and LB is 23.5 pF (typical), forming part of the tuned circuit with the antenna inductance. The n.c. pin must remain unconnected.

Does SL2S2002FTB,115 support password-protected EAS functionality?

Yes, SL2S2002FTB,115 supports password-protected EAS via its 32-bit EAS/AFI password mechanism. The EAS mode can be enabled (SET EAS), disabled (RESET EAS), or locked (LOCK EAS) only after transmitting the correct password using the SET PASSWORD command with password identifier 10h. This prevents unauthorized surveillance activation.

What is the memory organization of SL2S2002FTB,115?

SL2S2002FTB,115 contains 1024 bits of EEPROM organized into 32 blocks of 4 bytes each. Blocks 0–27 (896 bits) constitute user memory with configurable write protection. Blocks 28–31 store configuration data (UID, passwords, AFI, DSFID, EAS) and are not directly writable-access is controlled via dedicated ISO commands.

How does the FAST INVENTORY READ command improve throughput for SL2S2002FTB,115?

The FAST INVENTORY READ command (A1h) doubles the downstream data rate from the SL2S2002FTB,115 to the reader-from 13 kbit/s to 53 kbit/s-while maintaining standard timing for upstream communication. This cuts bulk block-read time by approximately half, accelerating inventory scans in high-volume retail or warehouse environments.

Is the UID of SL2S2002FTB,115 programmable or modifiable after manufacture?

No, the 64-bit UID of SL2S2002FTB,115 is factory-programmed during wafer test and permanently locked in silicon per ISO/IEC 15693-3. Bit 37 is set to logic 1 to indicate EAS/AFI password support, and the TAG type is fixed at "01h". The UID cannot be altered, overwritten, or duplicated-ensuring absolute uniqueness across all units.
