Product details
Overview
SL3S1003FUD/BG,003 from NXP Semiconductors is a UHF RFID Gen2 transponder IC (UCODE G2iM) in bare die form, designed for passive wireless identification and data storage. It delivers -17.5 dBm chip sensitivity, 256-bit EPC memory, 640-bit user memory, integrated Product Status Flag (PSF), and memory read protection - enabling item-level tagging, theft deterrence, and PCB tagging in retail, fashion, and electronics manufacturing.
For engineers reviewing the SL3S1003FUD/BG,003 datasheet, SL3S1003FUD/BG,003 pinout, SL3S1003FUD/BG,003 application, or SL3S1003FUD/BG,003 equivalent, this page provides verified technical context, exact pin functions for wafer-level integration, confirmed memory architecture, real-world use cases in supply chain and authentication, and two validated alternative parts with documented functional distinctions.
Technical Context
The SL3S1003FUD/BG,003 implements EPCglobal UHF Class-1 Generation-2 v1.2.0 protocol with full support for mandatory commands (SELECT, READ, WRITE, KILL, LOCK) and optional features including BlockWrite (32-bit), BlockPermalock, and custom PSF Alarm/ReadProtect/ChangeConfig. Its analog interface rectifies RF energy from 840–960 MHz readers to power digital control and EEPROM blocks.
Memory is organized across four banks: Reserved (64-bit), EPC (256-bit), TID (96-bit + 112-bit User TID), and User Memory (512-bit). Configuration is managed via two dedicated 16-bit words at EPC bank addresses 1F0h (Mem-Config-Word) and 200h (Config-Word), enabling runtime control of PSF, backscatter strength, and read protection without custom command dependency.
Key Specifications

FAQ
What is the primary function of SL3S1003FUD/BG,003 in an RFID system?
The SL3S1003FUD/BG,003 serves as a passive UHF RFID transponder IC compliant with EPCglobal Gen2 v1.2.0. It receives power and commands wirelessly from a reader via its RFP/RFN antenna interface, stores EPC and user data in on-chip EEPROM, and backscatters responses. Its core role is secure, long-range item identification with built-in PSF and read protection - all implemented without external power or microcontroller.
Does SL3S1003FUD/BG,003 support external power supply?
No. SL3S1003FUD/BG,003 is strictly a passive device powered solely by RF energy harvested from the reader's electromagnetic field. While the die includes a VDD bump, it is not functional in the G2iM version. External supply mode is exclusive to the G2iM+ variant (e.g., SL3S1013FUD/BG), where VDD enables boosted sensitivity (-27 dBm) and digital switch operation.
How does the Product Status Flag (PSF) work in SL3S1003FUD/BG,003?
The PSF in SL3S1003FUD/BG,003 is a configurable bit in the Config-Word (EPC bank address 20Fh) that acts as an electronic article surveillance flag. When set, it allows the tag to respond uniquely to an EAS_Alarm command or be selected via EPC SELECT - enabling fast, database-free alarm detection at retail exits or secure zones without modifying the EPC number itself.
Can SL3S1003FUD/BG,003 be used for secure authentication applications?
Yes. SL3S1003FUD/BG,003 supports bank-wise read protection for EPC, TID, and User Memory, plus a factory-locked 48-bit TID serial number. These features prevent cloning and unauthorized memory access. Combined with its 20-year data retention and -40 °C to +85 °C operating range, it meets baseline requirements for anti-counterfeiting in pharmaceuticals, luxury goods, and industrial spare parts.
What antenna design considerations apply to SL3S1003FUD/BG,003?
SL3S1003FUD/BG,003 requires a matched antenna connected between RFP (ungrounded) and RFN (grounded) terminals. Its high sensitivity (-17.5 dBm) and low Q-factor simplify design: small, low-cost single-port antennas achieve >5 m read range, and broadband tuning accommodates global 840–960 MHz operation. No DC blocking capacitor is needed - direct connection supports loop antenna topologies.
