NXP Semiconductors SL2S5002FTB,115

Overview

SL2S5002FTB,115 from NXP Semiconductors is an ISO/IEC 15693-compliant contactless RFID IC for smart label applications requiring privacy control, 1.5 m read range, 512-bit EEPROM, and password-protected destroy/privacy/EAS functions. It operates at 13.56 MHz with up to 53 kbit/s data transfer and is used in industrial asset tracking and library management systems.

For engineers reviewing the SL2S5002FTB,115 datasheet, SL2S5002FTB,115 pinout, SL2S5002FTB,115 application, or SL2S5002FTB,115 equivalent, key selection criteria include its XSON3 package, 3-terminal RF interface, 32-bit password security architecture, and compliance with ISO/IEC 18000-3 Mode 1 for vicinity identification systems.

Technical Context

The SL2S5002FTB,115 integrates an analog RF interface (13.56 MHz resonant coupling), digital controller with anticollision state machine, and 512-bit EEPROM organized in 16 blocks of 4 bytes. Its RF interface supports true anticollision, EAS, AFI, DSFID, and fast inventory page reads.

It implements three distinct 32-bit password domains-Privacy, Destroy, and EAS/AFI-with XOR-based authentication using GET RANDOM NUMBER responses. Memory access is controlled via block-level lock bits and password-protected commands including ENABLE PRIVACY (BAh) and DESTROY SLIX-L (B9h).

Key Specifications

Pinout & Package

FAQ

What is the primary function of the SL2S5002FTB,115 in an RFID system?

The SL2S5002FTB,115 serves as a contactless, battery-free RFID tag IC compliant with ISO/IEC 15693. It provides secure identification via a 64-bit UID, stores 512 bits of user-configurable data, and executes privacy, destruction, and EAS commands under 32-bit password control - all powered and communicated wirelessly at 13.56 MHz. Its role is to act as a programmable, tamper-resistant endpoint in vicinity identification systems.

Does the SL2S5002FTB,115 require an external power source?

No, the SL2S5002FTB,115 operates entirely without a battery. It derives power from the electromagnetic field generated by a compatible 13.56 MHz reader antenna through inductive coupling between its LA and LB terminals and the external resonant coil. This enables maintenance-free, decades-long operation in sealed or embedded label formats.

How does the privacy mode work on the SL2S5002FTB,115?

The SL2S5002FTB,115 enters Privacy mode upon successful execution of the ENABLE PRIVACY (BAh) command with a valid 32-bit XOR-calculated password. In this state, it ignores all commands except GET RANDOM NUMBER and SET PASSWORD. To exit, the correct Privacy password must be retransmitted via SET PASSWORD - ensuring that only authorized readers can restore full functionality.

Can the SL2S5002FTB,115 be used with standard ISO/IEC 15693 readers?

Yes, the SL2S5002FTB,115 is fully compliant with ISO/IEC 15693-1, -2, and -3, including mandatory commands (INVENTORY, STAY QUIET), optional commands (READ/WRITE SINGLE BLOCK, LOCK BLOCK), and custom NXP extensions. It interoperates with any reader supporting Mode 1 (13.56 MHz, 100% ASK, 26.48 kbit/s or 53 kbit/s) without firmware modification.

What is the significance of the "FTB" suffix in SL2S5002FTB,115?

The "FTB" suffix in SL2S5002FTB,115 denotes the XSON3 (SOT1122) plastic extremely thin small outline package - a 3-terminal, leadless surface-mount package measuring 1 × 1.45 × 0.5 mm. The "115" is a tape-and-reel ordering designation indicating packaging format and quantity; the device itself is functionally identical to SL2S5002FTB without the suffix.
