Product details
Overview
SL3S1004FUD/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, 1-kbit user memory, and operates across −40 °C to +85 °C. It enables high-read-range inventory tracking and brand authentication in logistics and luxury goods tagging.
For engineers reviewing the SL3S1004FUD/BGZ datasheet, SL3S1004FUD/BGZ pinout, SL3S1004FUD/BGZ application, or SL3S1004FUD/BGZ equivalent, this page provides verified technical context, wafer-level package details, EPC memory mapping, parallel encoding capability, and confirmed alternative options for UHF RFID tag design.
Technical Context
The SL3S1004FUD/BGZ implements a fully compliant EPCglobal v1.2.0 air interface with mandatory command support (Inventory, Read, Write, Kill, Lock) plus optional BlockPermalock (256-bit blocks) and Access. Its analog RF interface rectifies reader-supplied UHF energy to power digital control and EEPROM modules, enabling battery-free operation.
Digital functionality includes pre-serialization of the 96-bit EPC using the factory-locked 48-bit TID serial number, Tag Power Indicator for write-readiness selection, and Parallel Encoding mode-triggered via SELECT at address 202h-to accelerate multi-tag identification or bulk write operations without timing constraints.

Pinout & Package
SL3S1004FUD/BGZ is supplied as a gold-bumped bare die on an 8-inch (200 mm) sawn wafer, 120 µm thick, with 7 µm polyimide spacer. Die dimensions are 570 µm × 630 µm. Four pads-RF1, RF2, TP1, TP2-are arranged in chip corners; TP1 and TP2 are electrically disconnected after dicing and serve test-only purposes during wafer probe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RF1 | Antenna connector 1 | Primary RF input/output node; forms differential antenna interface with RF2 |
| RF2 | Antenna connector 2 | Secondary RF input/output node; symmetric with RF1 for stable impedance matching |
| TP1 | Test pad 1 | Wafer-level probe point only; electrically isolated post-dicing |
| TP2 | Test pad 2 | Wafer-level probe point only; electrically isolated post-dicing |
Key Features
| Feature | Design Value |
|---|---|
| Pre-serialization of 96-bit EPC | Automatically populates EPC with TID-derived 48-bit serial number-reduces encoding time by eliminating manual EPC initialization |
| Tag Power Indicator | Allows readers to filter tags with sufficient RF power before write attempts-prevents failed writes and improves encoding yield |
| Parallel Encoding mode | Enables simultaneous OPEN-state transition for multiple tags-accelerates bulk encoding and simplifies anti-collision sequencing |
| Untraceable command | Hides EPC/TID/user memory segments or reduces read range on demand-supports privacy-sensitive deployments and counterfeit deterrence |
| Product Status Flag (PSF) | Single-bit flag usable as EAS alarm without backend database-enables electronic article surveillance in retail loss prevention |
| Single-slit antenna compatibility | Supports mechanically stable antenna attachment with reduced process variation sensitivity-improves yield in high-volume label manufacturing |

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 |
|---|---|---|---|
| SL3S1014FUD/BGZ | UCODE 7xm+ variant with 2-kbit user memory and 384-bit ECDSA digital signature; identical pinout and wafer form factor | Required when cryptographic brand protection or extended payload storage (e.g., firmware version, calibration data) is needed | Select SL3S1014FUD/BGZ only if digital signature verification or >1-kbit user data is mandatory; otherwise SL3S1004FUD/BGZ offers optimal cost/performance balance |
| SL3S4012FUD/BGZ | UCODE 8xm generation: −21 dBm read sensitivity, 2-kbit user memory, EPCglobal Gen2v2 compliance, and enhanced interference rejection | Suitable for dense-reader environments (e.g., port terminals) or where future-proofing against Gen2v2 mandates is required | Choose SL3S4012FUD/BGZ for new designs targeting highest sensitivity or regulatory readiness; SL3S1004FUD/BGZ remains optimal for cost-sensitive Gen2v1 deployments |
Compared with SL3S1014FUD/BGZ, SL3S1004FUD/BGZ trades digital signature and extra memory for lower unit cost and proven Gen2v1 interoperability; versus SL3S4012FUD/BGZ, it offers mature supply chain stability and simpler reader firmware requirements at modest sensitivity reduction.

FAQ
What is the primary function of SL3S1004FUD/BGZ in an RFID system?
SL3S1004FUD/BGZ functions as a passive UHF RFID tag IC compliant with EPCglobal v1.2.0. It receives power and commands wirelessly from a reader via its RF1/RF2 interface, executes mandated protocols (Read, Write, Kill), stores 1-kbit of user data and a 448-bit EPC, and backscatters responses. Its role is to serve as a durable, field-programmable identifier in logistics, authentication, and tracking systems-without onboard power.
Does SL3S1004FUD/BGZ support digital signature verification like SL3S1014FUD/BGZ?
No, SL3S1004FUD/BGZ does not support digital signature verification. The 384-bit ECDSA digital signature feature is exclusive to the UCODE 7xm+ variant (e.g., SL3S1014FUD/BGZ). SL3S1004FUD/BGZ provides all core UCODE 7xm capabilities-including pre-serialization, Tag Power Indicator, and Parallel Encoding-but omits the cryptographic signature block present in the + variant.
What antenna configurations are compatible with SL3S1004FUD/BGZ?
SL3S1004FUD/BGZ supports differential antenna interfaces via RF1 and RF2, including single-slit antennas for mechanical stability and loop antennas enabled by DC connection between RF pads. Its impedance profile allows reuse of existing UCODE 7 antenna designs, and its high sensitivity (−19 dBm) permits smaller, lower-cost antennas without sacrificing read range-validated for operation with standard linear-polarized UHF antennas.
How is memory organized in SL3S1004FUD/BGZ, and what is locked versus user-accessible?
SL3S1004FUD/BGZ organizes memory into four banks: Reserved (64-bit passwords), EPC (448-bit, including CRC and PC), TID (96-bit, factory-locked with 48-bit serial number), and User Memory (1024-bit). The TID and configuration word (at EPC address 200h) are permanently locked; EPC and User banks can be locked/unlocked via standard EPC commands. Pre-serialization uses the immutable TID serial number to auto-populate the EPC.
Can SL3S1004FUD/BGZ be used in environments with extreme temperature variation?
Yes, SL3S1004FUD/BGZ is rated for continuous operation from −40 °C to +85 °C. This specification is validated across wafer lots and supports deployment in uncontrolled logistics environments (e.g., outdoor shipping containers), automotive manufacturing floors, and cold-chain distribution-where thermal cycling and ambient extremes would degrade lesser tag ICs. Data retention remains guaranteed for 20 years within this range.
