Product details
Overview
SL3S1203AC0,118 from NXP Semiconductors is a UHF RFID Gen2 transponder IC compliant with EPCglobal v1.2.0, featuring 128-bit EPC memory, 64-bit TID with factory-locked 32-bit serial number, -18 dBm passive sensitivity, integrated Product Status Flag (PSF), and read protection. It operates across 840–960 MHz and supports item-level tagging in retail apparel and PCB authentication in consumer electronics.
For engineers reviewing the SL3S1203AC0,118 datasheet, SL3S1203AC0,118 pinout, SL3S1203AC0,118 application, or SL3S1203AC0,118 equivalent, this page delivers verified technical context, exact package mapping to SOT886 (XSON6), confirmed pin functions, real-world use value for wireless activation and tamper detection, and two validated alternative parts with documented functional distinctions.
Technical Context
The SL3S1203AC0,118 implements a passive UHF RFID air interface per EPCglobal Class-1 Generation-2 (v1.2.0), with analog RF front-end including rectifier, voltage regulator, and backscatter modulation transistor. Its digital control block handles anti-collision, protocol state machines, EEPROM interface, and custom command execution including ChangeConfig.
It integrates a 16-bit configuration word at EPC bank address 200h enabling feature control - PSF alarm, read range reduction (+12 dBm threshold), EPC/TID read protection, and backscatter strength selection - all accessible via standard EPC READ/WRITE commands when unlocked or via ChangeConfig custom command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| EPC Memory | 128 bits - stores unique item identifier; enables EPC-compliant inventory and traceability |
| TID Memory | 64 bits with 32-bit factory-locked serial number - provides immutable chip identity and anti-counterfeiting traceability |
| Passive Sensitivity | -18 dBm - achieves extended read range with simple single-port antenna designs |
| Operating Frequency | 840–960 MHz - supports global UHF RFID deployments without hardware change |
| Read Protection | Bank-wise (EPC & TID) - prevents unauthorized memory access while allowing selective inventory |
| Product Status Flag (PSF) | Integrated flag at EPC address 20Fh - enables EAS functionality without backend database |
| Temperature Range | -40 °C to +85 °C - ensures reliable operation in industrial, retail, and automotive environments |
Pinout & Package
SL3S1203AC0,118 is packaged in SOT886 (XSON6), a plastic extremely thin small outline package with 6 terminals, body size 1 × 1.45 × 0.5 mm. The package supports direct flip-chip mounting on flexible substrates and is optimized for high-yield label assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFP | Ungrounded antenna connector - connects to high-impedance side of loop or dipole antenna |
| 2 | n.c. | Not connected - no internal connection; must remain unconnected in layout |
| 3 | RFN | Grounded antenna connector - connects to low-impedance/ground side of antenna structure |
| 4 | OUT | Output pin - used for digital switch, data transfer, or tamper alarm signaling in G2iL+ variants |
| 5 | n.c. | Not connected - no internal connection; must remain unconnected in layout |
| 6 | VDD | External supply terminal - enables external 1.85 V bias to boost sensitivity to -27 dBm and equalize read/write range |
Key Features
| Feature | Design Value |
|---|---|
| PSF Alarm | Enables EAS functionality using built-in Product Status Flag - triggers alarm response without reader-side database lookup |
| Real Read Range Reduction (4R) | Reduces chip sensitivity to +12 dBm at startup - limits read distance to centimeters for privacy-sensitive applications |
| Bank-wise Read Protection | Independent locking of EPC and TID memory banks - allows selective inventory while blocking sensitive identifiers |
| Backscatter Strength Control | Two-level configurable backscatter output - balances read reliability against interference in dense-reader environments |
| Extended TID with Serial Number | 32-bit factory-locked serial number embedded in 64-bit TID - provides cryptographically verifiable chip uniqueness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar UHF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SL3S1213AC0,118 | G2iL+ variant with additional features: external supply mode, tag tamper alarm, RF field detection, digital switch, and data transfer mode | Required for applications needing active interaction (e.g., wireless firmware download, tamper-evident seals) | Select SL3S1213AC0,118 only if G2iL+ features are needed; SL3S1203AC0,118 suffices for standard EPC/TID tagging |
| SL900AATP,118 | Ultra-low-power sensor transponder with integrated temperature sensor, 2 kB EEPROM, and energy harvesting support | Used where environmental monitoring or local data logging is required alongside RFID identification | Choose SL900AATP,118 for sensor-augmented tracking; SL3S1203AC0,118 is optimal for cost-sensitive, high-volume item tagging |
Compared with SL3S1213AC0,118, the SL3S1203AC0,118 omits external supply and tamper alarm circuitry - reducing die size and cost while retaining full EPCglobal v1.2.0 compliance and PSF functionality. Versus SL900AATP,118, it trades sensor capability and memory depth for lower power consumption and higher read sensitivity in pure identification roles.

FAQ
What is the primary function of SL3S1203AC0,118 in an RFID system?
The SL3S1203AC0,118 serves as a passive UHF RFID transponder IC compliant with EPCglobal Class-1 Generation-2 v1.2.0. It stores and wirelessly exchanges EPC and TID data with readers, supports bank-wise read protection, and implements the Product Status Flag (PSF) for electronic article surveillance. Its -18 dBm sensitivity enables reliable operation with compact antennas in retail and industrial settings.
Does SL3S1203AC0,118 support external power supply?
No, SL3S1203AC0,118 does not support external supply mode. That capability is exclusive to the G2iL+ variant (e.g., SL3S1213AC0,118). The SL3S1203AC0,118 operates solely in passive mode, deriving all power from the reader's RF field, with a sensitivity of -18 dBm. Its VDD pin is not functional for external bias in this version.
How is memory protected on SL3S1203AC0,118?
SL3S1203AC0,118 supports bank-wise read protection for both EPC and TID memory sections, controlled via bit flags in the configuration word at EPC address 200h. When enabled, unauthorized reads return zeros. Protection is enforced at the protocol level and persists across RF cycles. The 32-bit kill and access passwords further secure write operations and permanent disablement.
What package type is used for SL3S1203AC0,118?
SL3S1203AC0,118 is supplied in SOT886 (XSON6) - a plastic extremely thin small outline package with 6 terminals, body dimensions of 1.0 × 1.45 × 0.5 mm. This package is optimized for flip-chip mounting on flexible inlays and supports high-throughput label conversion processes with robust bump interconnects.
Can SL3S1203AC0,118 be used for tamper detection?
SL3S1203AC0,118 does not include the tag tamper alarm feature - that is reserved for the G2iL+ variant (SL3S1213AC0,118). However, it does implement the Product Status Flag (PSF), which can be configured as an EAS alarm indicator. PSF activation requires reader-side command execution (EAS_Alarm or SELECT2) and does not rely on physical break detection like the G2iL+ tamper alarm.
