Product details
Overview
SL3S1014FUD/BG1Z from NXP Semiconductors is a UHF RFID tag IC in the UCODE 7xm+ family, designed for passive wireless identification in demanding logistics and authentication applications. It delivers -19 dBm read sensitivity, 2-kbit user memory, and a factory-programmed 384-bit ECDSA digital signature (NIST P-192) over its 96-bit TID for silicon-level origin verification. It operates across -40 °C to +85 °C and supports EPCglobal v1.2.0 with parallel encoding and Tag Power Indicator functionality.
For engineers reviewing the SL3S1014FUD/BG1Z datasheet, SL3S1014FUD/BG1Z pinout, SL3S1014FUD/BG1Z application, or SL3S1014FUD/BG1Z equivalent, key selection criteria include verified digital signature capability, 2-kbit user memory allocation, RF sensitivity for extended read range, compatibility with single-slit antenna designs, and support for BlockPermalock and Untraceable commands in high-security tagging environments.
Technical Context
The SL3S1014FUD/BG1Z implements a CMOS 0.14 μm analog/digital architecture with dedicated RF interface (RF1/RF2), EEPROM memory bank organization (EPC, TID, User, Reserved), and digital control logic supporting EPCglobal v1.2.0 mandatory and optional commands including Access, BlockPermalock (256-bit), and BlockWrite (32-bit).
It integrates custom features including ReadSignature (UCODE 7xm+ only), Untraceable mode for EPC/TID/user memory masking and dynamic read-range reduction, and hardware-assisted Product Status Flag (PSF) enabling EAS functionality without backend database dependency.

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 |
|---|---|---|---|
| SL3S1024FUD/BG1 | UCODE 7xm-2k variant without digital signature; identical 2-kbit user memory and -19 dBm sensitivity | Lacks 384-bit ECDSA signature; unsuitable for cryptographic brand protection or anti-counterfeit verification | Select when cost-sensitive asset tracking requires full memory but no silicon-level authentication |
| SL3S1004FUD/BG1 | UCODE 7xm-1k variant with 1-kbit user memory; same sensitivity, temperature range, and feature set except digital signature | Halves user memory capacity; insufficient for complex serialization, multi-field logs, or firmware metadata storage | Select only for basic EPC-only tagging where memory demand is ≤1 kbit and signature verification is unnecessary |
Compared with SL3S1024FUD/BG1 and SL3S1004FUD/BG1, SL3S1014FUD/BG1Z uniquely delivers cryptographically verifiable origin assurance via factory-programmed ECDSA signature-enabling trust-critical applications where memory size alone is insufficient for security requirements.

FAQ
What is the digital signature capability of SL3S1014FUD/BG1Z?
SL3S1014FUD/BG1Z includes a factory-preprogrammed 384-bit ECDSA digital signature based on NIST P-192 (secp192r1), cryptographically binding the 96-bit TID to NXP's public key. The ReadSignature command retrieves this signature for offline verification using standard ECDSA libraries-no cloud dependency required. This capability is exclusive to UCODE 7xm+ variants and is absent in SL3S1024FUD/BG1 and SL3S1004FUD/BG1.
Does SL3S1014FUD/BG1Z support EPCglobal v1.2.0 fully?
Yes, SL3S1014FUD/BG1Z implements all mandatory EPCglobal v1.2.0 commands and selected optional ones including Access, BlockPermalock (256-bit), and BlockWrite (32-bit). It also adds custom commands-Untraceable and ReadSignature-that extend functionality beyond the base specification while maintaining interoperability with compliant readers.
What is the memory organization of SL3S1014FUD/BG1Z?
SL3S1014FUD/BG1Z organizes memory into four banks: Reserved (64-bit passwords), EPC (up to 448-bit), TID (96-bit, factory-locked with 48-bit serial number), and User (2048-bit). A configuration word at EPC address 200h controls features like Parallel Encoding and Tag Power Indicator. The TID structure includes Class ID, Mask Designer ID, Model Number, XTID header, and serial number per GS1 EPC Tag Data Standard 1.9.
How does the Tag Power Indicator function in SL3S1014FUD/BG1Z?
The Tag Power Indicator in SL3S1014FUD/BG1Z is a hardware feature activated via bit 204h in the EPC configuration word. When enabled, it allows the reader to determine whether the SL3S1014FUD/BG1Z has received sufficient RF energy to reliably execute write operations-preventing partial writes or corruption. This is especially valuable in variable-field-strength environments like conveyor-based encoding stations.
Is SL3S1014FUD/BG1Z compatible with single-slit antenna designs?
Yes, SL3S1014FUD/BG1Z is explicitly designed for single-slit antenna compatibility, as confirmed in Section 2.1 and Section 2.2.3 of the datasheet. This mechanical design choice improves antenna connection stability and simplifies label manufacturing-particularly beneficial for flexible, washable, or high-durability RFID labels used in logistics and apparel tagging.
