Product details
Overview
SL3S1202FTB1,115 from NXP Semiconductors is a passive UHF RFID tag IC compliant with EPCglobal Class 1 Generation 2 (Gen2) standard, designed for high-speed anti-collision inventory in supply chain and logistics applications. It features 240-bit EPC memory, 64-bit TID with unique 32-bit serial number, 840–960 MHz operating frequency, -15 dBm minimum operating power, and XSON3 (SOT1122) package with 3 terminals.
For engineers reviewing the SL3S1202FTB1,115 datasheet, SL3S1202FTB1,115 pinout, SL3S1202FTB1,115 application, or SL3S1202FTB1,115 equivalent, this page delivers verified technical context, Gen2 air interface timing constraints, calibrated backscatter performance, EAS and memory protection functionality, and real-world deployment guidance for item-level tagging and asset tracking systems.
Technical Context
The SL3S1202FTB1,115 implements a fully integrated analog RF interface with on-chip voltage regulator and charge pump, enabling operation from propagative RF energy without external power. Its digital controller executes EPC Gen2 protocol state machines-including Query, ACK, Req_RN, Read, Write, Kill, and Calibrate-while managing EEPROM access and session-based anti-collision arbitration across S0–S3 sessions.
It supports dual modulation schemes: DSB-ASK/SSB-ASK/PR-ASK with PIE encoding for reader-to-tag (R→T) at 40–160 kbit/s, and ASK/PSK backscatter with FM0 or Miller subcarrier for tag-to-reader (T→R) at 40–640 kbit/s. The chip integrates CRC-5 for Query command integrity and CRC-16 for EPC/PC/TID data protection, with built-in EAS alarm and read-protect commands for retail security and data confidentiality.

| Low-Q Antenna Interface | Optimized impedance (18.6 – j171.2 Ω @ 915 MHz) and high input capacitance reduce sensitivity to material detuning |
Applications
| Supply Chain Management | Item-Level Tagging |
|---|---|
Use Scenario: High-volume pallet/case tracking across distribution centers using fixed-mount UHF readers. IC Role / Device Role / Timing Role: Passive Gen2 tag IC providing EPC-encoded product identity and session-managed anti-collision during rapid inventory sweeps. Use Value: Achieves >7 m read range under ETSI 2 W ERP in Europe, enabling single-reader coverage of entire pallet lanes without line-of-sight. |

IC Role / Device Role / Timing Role: Secure, password-protected RFID tag supporting EAS alarm and read-protected TID/EPC to prevent counterfeiting. Use Value: Integrated 32-bit kill password and EAS command allow irreversible deactivation and retail theft deterrence without cloud dependency. |
| Asset Management | Container Identification |
Use Scenario: Reusable IT equipment or medical device tracking across hospital or enterprise campuses. IC Role / Device Role / Timing Role: Long-life EEPROM (50-year data retention) and 100k write cycles enable repeated reassignment and firmware update logging. Use Value: Supports field reprogramming of user memory for maintenance history, calibration dates, and ownership records over multi-year service life. |
Use Scenario: Seaport container ID verification using handheld readers in metallic, high-interference environments. IC Role / Device Role / Timing Role: Robust backscatter modulation (FM0/Miller) and jammer suppression (>−4 dB at ≥1 MHz) ensure reliable reads near RF-noisy infrastructure. Use Value: Low Q-factor and stable impedance maintain link budget on metal-mount inlays, reducing false negatives in dense container yards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar UHF RFID tag IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SL3S1002FTB1 | G2XM variant with 512-bit user memory vs. G2XL's 0-bit user memory; identical EPC/TID, package, and Gen2 compliance | Suitable where field-updatable user data (e.g., batch lot, calibration logs) is required beyond EPC/TID | Select SL3S1002FTB1 only if >0 user memory is needed; SL3S1202FTB1,115 optimizes cost and size for pure EPC/TID use cases |
| SL900A | Temperature-sensing SoC with integrated ADC, sensor interface, and 2 kB EEPROM; operates at same 860–960 MHz band but adds sensing capability | Targeted at cold-chain monitoring, predictive maintenance, and environmental compliance-not pure identification | Choose SL900A when ambient temperature logging or sensor-triggered alerts are mandatory; SL3S1202FTB1,115 remains optimal for cost-sensitive, high-volume identification-only deployments |
Compared with SL3S1002FTB1, SL3S1202FTB1,115 reduces die area and BOM cost by omitting user memory while retaining full Gen2 feature set and EAS/read-protection; versus SL900A, it delivers higher read sensitivity and lower power threshold for maximum range in static identification roles.

FAQ
What is the primary function of the SL3S1202FTB1,115 in an RFID system?
The SL3S1202FTB1,115 serves as a passive UHF RFID tag IC compliant with EPCglobal Gen2 standard. It receives operating power and commands wirelessly from an interrogator, stores EPC and TID data in on-chip EEPROM, executes anti-collision protocols, and backscatters responses. Its role is strictly identification and secure data exchange-not sensing, processing, or active transmission.
Does the SL3S1202FTB1,115 support user memory, and how does it differ from SL3S1002FTB1?
No, the SL3S1202FTB1,115 is the G2XL variant and provides zero user memory. In contrast, SL3S1002FTB1 is the G2XM variant with 512-bit user memory. Both share identical EPC (240-bit), TID (64-bit), package (XSON3/SOT1122), and Gen2 feature set-including EAS, read protection, and kill/access passwords-but differ solely in user memory allocation.
What antenna configurations are supported by the SL3S1202FTB1,115?
The SL3S1202FTB1,115 supports both dipole and loop antenna topologies via its RFP (ungrounded) and RFN (grounded) terminals. Its low Q-factor and 1.02 pF input capacitance simplify matching to printed antennas on diverse substrates-including paper, PET, and on-metal inlays-without requiring discrete matching components in most designs.
How does the EAS feature of the SL3S1202FTB1,115 operate without backend infrastructure?
The SL3S1202FTB1,115 implements standalone EAS alarm mode via the EAS command. When activated, the tag responds to a specific EAS interrogation signal with a predefined backscatter pattern-triggering local alarms at store exits. No database lookup, network connection, or cloud service is required, making it ideal for retail loss prevention with minimal infrastructure.
What is the significance of the "115" suffix in SL3S1202FTB1,115?
The "115" suffix denotes the tape-and-reel packaging option per NXP's ordering convention: SL3S1202FTB1,115 indicates the XSON3 device supplied in 7-inch reel format with standard orientation (T1), moisture sensitivity level (MSL) 3, and dry pack per J-STD-033. It does not indicate a functional or revision difference from SL3S1202FTB1.
