Product details
Overview
SL3S1014FUD/BGZ from NXP Semiconductors is a UHF RFID tag IC in the UCODE 7xm+ family, designed for passive EPCglobal v1.2.0–compliant systems. It delivers −19 dBm read sensitivity, 2-kbit user memory, and a factory-programmed 384-bit ECDSA digital signature for brand authentication in luxury goods and high-value asset tracking.
For engineers reviewing the SL3S1014FUD/BGZ datasheet, SL3S1014FUD/BGZ pinout, SL3S1014FUD/BGZ application, or SL3S1014FUD/BGZ equivalent, this page provides verified technical context, memory architecture details, antenna interface specifications, and real-world deployment guidance for supply chain, automotive process optimization, and anti-counterfeiting use cases.
Technical Context
The SL3S1014FUD/BGZ implements a three-block architecture: analog RF interface (with rectifier, VREG, and modulation transistor), digital control (state machines, protocol engine, EEPROM interface), and 2-kbit EEPROM memory organized across four banks (Reserved, EPC, TID, User). It supports all mandatory EPCglobal v1.2.0 commands plus optional BlockPermalock (256-bit blocks) and custom Untraceable/ReadSignature commands.
Its symmetric RF1/RF2 inputs enable single-slit antenna designs with mechanical stability and reusability from UCODE 7 layouts. The chip operates from −40 °C to +85 °C, sustains 100,000 write cycles, and retains data for 20 years - validated for industrial label manufacturing and dense-reader environments.
Key Specifications

Pinout & Package
SL3S1014FUD/BGZ is supplied as a gold-bumped bare die on an 8-inch wafer (200 mm diameter, 120 µm thickness), with polyimide spacer (7 µm) isolating the active circuit from antenna coupling. Die dimensions are 570 µm × 630 µm; RF pad-to-pad distance is 480 µm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF1 | Antenna connector 1 | Symmetric RF input terminal; enables balanced impedance matching for single-slit or loop antennas. |
| RF2 | Antenna connector 2 | Symmetric RF input terminal; supports identical layout reuse from prior UCODE 7 designs. |
| TP1 | Test pad 1 | Electrically disconnected after dicing; used only for wafer-level functional test and alignment. |
| TP2 | Test pad 2 | Electrically disconnected after dicing; used only for wafer-level functional test and alignment. |
Key Features
| Feature | Design Value |
|---|---|
| Parallel encoding mode | Enables simultaneous OPEN-state activation of multiple tags, accelerating bulk encoding by >3× versus sequential methods. |
| Tag Power Indicator | Allows readers to filter tags with insufficient RF energy before write attempts - eliminating failed writes and improving throughput. |
| Pre-serialization of 96-bit EPC | Factory embeds 48-bit TID serial number into EPC at wafer level, cutting post-die encoding time by ~70% in label production. |
| Untraceable command | Supports selective EPC/TID hiding and dynamic read-range reduction - critical for privacy-sensitive retail or secure logistics deployments. |
| Product Status Flag (PSF) | Single-bit flag enables EAS (Electronic Article Surveillance) functionality without backend database, supporting loss prevention at point-of-exit. |

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 |
|---|---|---|---|
| SL3S1004FUD/BG1 | UCODE 7xm variant with 1-kbit user memory, no digital signature, same −19 dBm sensitivity and pinout. | Lacks cryptographic authentication; suitable for cost-sensitive inventory where brand verification is not required. | Select SL3S1004FUD/BG1 only when 2-kbit memory and ECDSA signature are unnecessary - reduces unit cost by ~18%. |
| SL900A | Temperature-sensing RFID IC with 2-kbit memory, but −21 dBm read sensitivity and no EPCglobal v1.2.0 compliance. | Supports sensor logging but requires proprietary reader firmware; incompatible with standard EPC infrastructure. | Choose SL900A only if ambient temperature monitoring is mandatory and EPC interoperability is secondary. |
Compared with SL3S1004FUD/BG1, SL3S1014FUD/BGZ adds verifiable brand protection via ECDSA; compared with SL900A, it guarantees drop-in compatibility with existing EPCglobal v1.2.0 readers while omitting sensor overhead.

FAQ
What is the primary function of SL3S1014FUD/BGZ in an RFID system?
SL3S1014FUD/BGZ serves as a passive UHF RFID tag IC compliant with EPCglobal v1.2.0. It receives RF energy from a reader, powers its internal circuitry, stores up to 2-kbit of user data and a 384-bit ECDSA digital signature, and backscatters responses. Its role is to provide secure, long-range identification and authenticated data storage without onboard power.
Does SL3S1014FUD/BGZ support cryptographic verification out of the box?
Yes. SL3S1014FUD/BGZ ships with a factory-programmed 384-bit digital signature based on ECDSA (NIST P-192) tied to its unique 48-bit TID. The ReadSignature command retrieves this signature, enabling offline verification using the published NXP public key - no pre-shared secrets or network connection required.
How does the Untraceable feature work on SL3S1014FUD/BGZ?
The Untraceable command on SL3S1014FUD/BGZ lets users selectively hide EPC, TID, or user memory content and toggle read range between normal and reduced states. It operates only from the secured state and modifies backscatter behavior dynamically - for example, hiding EPC fields above address 20h or reducing effective read distance by >50% for privacy enforcement.
Can SL3S1014FUD/BGZ be used with existing UCODE 7 antenna designs?
Yes. SL3S1014FUD/BGZ maintains identical RF impedance characteristics and symmetric RF1/RF2 terminals as UCODE 7, enabling direct reuse of single-slit antenna layouts. The 480 µm RF pad spacing and CMOS 0.14 µm process ensure mechanical and electrical compatibility without retuning or redesign.
What memory organization does SL3S1014FUD/BGZ use, and how is it accessed?
SL3S1014FUD/BGZ organizes memory into four EPCglobal-defined banks: Reserved (64-bit passwords), EPC (448-bit), TID (96-bit locked serial), and User (2048-bit). Access occurs via standard EPC commands (READ/WRITE/ACCESS); configuration bits at EPC address 200h control features like Parallel Encoding and Tag Power Indicator - all using native protocol syntax.
