Product details
Overview
SL2S2102FTB,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 range, and password-protected EAS/AFI functionality. It serves as a secure, battery-free tag IC in pharmaceutical item-level tagging and library asset tracking systems.
For engineers reviewing the SL2S2102FTB,115 datasheet, SL2S2102FTB,115 pinout, SL2S2102FTB,115 application, or SL2S2102FTB,115 equivalent, this page delivers verified technical context, exact pin roles for XSON3 (SOT1122) packaging, memory security architecture, anticollision behavior, and two validated alternative parts with documented functional distinctions.
Technical Context
The SL2S2102FTB,115 implements a fully compliant ISO/IEC 15693-2/3 analog RF interface with 13.56 MHz carrier, 53 kbit/s high-speed data transfer, and true deterministic anticollision supporting simultaneous multi-tag interrogation. Its digital controller handles protocol state machines, UID validation, and EEPROM access control without internal power.
It integrates a 1024-bit EEPROM organized into 32 × 4-byte blocks - 128 bits reserved for configuration (UID, passwords, AFI/EAS flags), 896 bits user-accessible - with per-block write lock, 50-year data retention, and 100,000 write cycles. The IC uses passive inductive coupling via LA/LB antenna terminals and requires no onboard voltage source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Standard | ISO/IEC 15693-2/3 and ISO/IEC 18000-3 Mode 1 compliant; ensures interoperability with global vicinity readers. |
| Operating Frequency | 13.56 MHz ISM band; enables license-free worldwide deployment and simple printed antenna integration. |
| Read/Write Distance | Up to 1.5 m (gate width); determined by reader field strength and antenna geometry - no battery required. |
| EEPROM Capacity | 1024 bits (32 blocks × 4 bytes); 896 bits user memory with configurable block-level write protection. |

Pinout & Package
SL2S2102FTB,115 is housed in a plastic extremely thin small outline package (XSON3, SOT1122) measuring 1.0 × 1.45 × 0.5 mm with three terminals and no leads. The package supports wafer-level bumping and is optimized for embedding in thin-label laminates.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LB) | Antenna RF input | One terminal of resonant LC tank; connects to one side of external coil - forms tuning capacitance with internal Ci = 97 pF. |
| 2 (LA) | Antenna RF input | Second terminal of resonant LC tank; connects to opposite side of external coil - completes 13.56 MHz coupling path. |
| 3 (n.c.) | Not connected | No internal bond; electrically isolated - must remain unconnected on PCB or label substrate to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| True anticollision | Deterministic ISO/IEC 15693-3 algorithm enabling reliable concurrent identification of >100 tags in reader field. |
| Fast inventory read | Custom A1h command delivers 53 kbit/s uplink data rate - twice standard ISO speed - accelerating bulk tag enumeration. |
| Password-protected EAS/AFI | 32-bit XOR password (via B2h/B3h commands) secures electronic article surveillance and application family filtering functions. |
| Write endurance & retention | 100,000 write cycles and 50-year data retention meet industrial labeling lifecycle requirements for reusable assets. |
| Configuration lock granularity | Independent lock bits for DSFID, AFI, EAS, and each 4-byte user block - enables fine-grained memory access control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RFID tag IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SL2S2002FTB,115 | Lower internal capacitance (Ci = 23.5 pF); optimized for smaller antenna geometries and shorter-range, high-density tag layouts. | Better suited for compact labels where antenna area is constrained (e.g., cosmetic packaging, small medical devices). | Select SL2S2002FTB,115 when antenna size limits resonant Q-factor and maximum read distance is secondary to spatial efficiency. |
| SL2S2102FUD | Same core functionality but delivered as bumped wafer (120 μm thickness); requires custom flip-chip assembly instead of surface-mount XSON3. | Targeted at ultra-thin flexible labels or inlays where 0.5 mm package height is prohibitive and wafer-level integration is feasible. | Choose SL2S2102FUD only for volume production with wafer-level bonding capability and strict thickness budgets (<0.2 mm). |
Compared with SL2S2102FTB,115, SL2S2002FTB,115 offers tighter antenna tuning for space-constrained deployments, while SL2S2102FUD trades package convenience for mechanical thinness - neither is pin-compatible, and both require antenna re-tuning due to differing Ci values.

FAQ
What is the internal capacitance (Ci) value of SL2S2102FTB,115 and why does it matter?
The SL2S2102FTB,115 has a typical internal capacitance (Ci) of 97 pF between LA and LB pins. This value directly determines the resonant frequency with the external antenna coil - accurate Ci knowledge is essential for optimizing read range and impedance matching during antenna design. Using the wrong Ci value causes detuning and reduced coupling efficiency.
Does SL2S2102FTB,115 support password-protected write access to user memory blocks?
No - SL2S2102FTB,115 supports per-block write lock bits and password-protected EAS/AFI/DSFID functions, but user memory block writes are controlled solely by lock bits, not passwords. Passwords apply exclusively to EAS activation, AFI modification, and DSFID updates per ISO/IEC 15693-3 and NXP's configuration documentation.
Can SL2S2102FTB,115 operate at full 1.5 m range with any antenna design?
No - the 1.5 m specification assumes optimal antenna geometry (e.g., 10–15 cm² loop, matched inductance) and high-power reader field (≥1.5 A/m). Real-world range depends on coil size, Q-factor, reader output, and environmental interference. SL2S2102FTB,115's 97 pF Ci requires corresponding inductance tuning - mismatched antennas reduce effective range significantly.
How is the UID of SL2S2102FTB,115 structured and can it be altered?
The UID of SL2S2102FTB,115 is a fixed 64-bit value programmed during wafer test per ISO/IEC 15693-3, containing NXP's manufacturer code "04h", SLIX type "01h", and unique serial number. Bit 37 indicates EAS/AFI password support. It cannot be altered, erased, or rewritten - ensuring permanent, globally unique identification for every SL2S2102FTB,115 unit shipped.
What commands enable fast bulk reading of multiple blocks in SL2S2102FTB,115?
SL2S2102FTB,115 supports INVENTORY READ (A0h) and FAST INVENTORY READ (A1h) commands. A1h doubles the uplink data rate to 53 kbit/s and is ideal for rapid multi-block reads across large tag populations. Both commands retain full ISO/IEC 15693-3 anticollision compliance and return CRC-protected data without host-side buffering overhead.
