Product details
Overview
SL3S1205FUD2/HAPBZ from NXP Semiconductors is a UCODE 8 ultra-high-frequency RFID IC die designed for passive tag applications in retail and supply chain systems. It delivers -23 dBm read sensitivity, supports EPC Gen2v2 protocol, features pre-serialized 96-bit EPC with factory-locked 48-bit unique serial number in TID, and enables long-range inventory reads via broadband antenna coupling.
For engineers reviewing the SL3S1205FUD2/HAPBZ datasheet, SL3S1205FUD2/HAPBZ pinout, SL3S1205FUD2/HAPBZ application, or SL3S1205FUD2/HAPBZ equivalent, this page provides verified technical context, memory architecture details, EAS-capable Product Status Flag implementation, Self Adjust feature activation logic, and wafer-level mechanical specifications for label integration planning.
Technical Context
The SL3S1205FUD2/HAPBZ implements a CMOS 0.14 μm analog/digital/EEPROM architecture with RF1/RF2 antenna interface terminals, integrated charge pump, and demodulator/rectifier circuitry optimized for 860–960 MHz operation. Its digital control block handles EPC Gen2v2 command parsing-including mandatory KILL/LOCK and optional ACCESS/BlockWrite/Untraceable-without custom firmware.
Memory organization includes four banks: Reserved (64-bit), EPC (128-bit), TID (96-bit locked), and no User Memory (0-bit), with configuration word at EPC address 200h enabling Self Adjust, Brand Identifier, and PSF functionality via standard SELECT commands. TP1/TP2 test pads are electrically disconnected post-dicing and serve only probe-based wafer testing.

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 |
|---|---|---|---|
| SL3S1215FUD2/HAPBZ | UCODE 8m variant with 32-bit User Memory; identical RF sensitivity, TID structure, and EPC Gen2v2 compliance | Required when field-deployable user data storage (e.g., batch codes, maintenance logs) is needed beyond EPC/TID | Select SL3S1215FUD2/HAPBZ only if 32-bit writable memory is required; SL3S1205FUD2/HAPBZ optimizes cost and die area for pure EPC/TID use cases |
| SL900A | Sensor-enabled RFID IC with temperature logging, 2 kB EEPROM, and AES-128 encryption; read sensitivity -19 dBm (4 dB weaker) | Used in cold-chain monitoring, pharmaceutical traceability, and secure asset tracking where environmental sensing is mandatory | Choose SL900A only when sensor capability or cryptographic security is required; SL3S1205FUD2/HAPBZ offers superior RF performance for pure identification tasks |
Compared with SL3S1215FUD2/HAPBZ, SL3S1205FUD2/HAPBZ reduces die area and cost by omitting User Memory while retaining identical EPC capacity, TID integrity, and EAS functionality; versus SL900A, it trades sensor features for higher sensitivity and lower power consumption in static identification roles.

FAQ
What is the primary function of SL3S1205FUD2/HAPBZ in an RFID system?
SL3S1205FUD2/HAPBZ functions as a passive UHF RFID tag IC that receives power and commands from a reader via RF coupling through its RF1/RF2 terminals, processes EPC Gen2v2 protocol instructions, and backscatters stored EPC and TID data. It does not require an external power source and operates entirely from harvested RF energy.
Does SL3S1205FUD2/HAPBZ include user-writable memory?
No, SL3S1205FUD2/HAPBZ provides 0-bit User Memory per its UCODE 8 specification. It allocates all non-reserved memory to EPC (128-bit) and TID (96-bit locked), with no provision for customer-defined data storage. For 32-bit User Memory, the SL3S1215FUD2/HAPBZ variant must be selected.
How is the Product Status Flag (PSF) implemented in SL3S1205FUD2/HAPBZ?
The PSF is a permanent bit located at EPC memory address 20Fh. It is activated by writing "1" using a standard EPC WRITE command when the EPC bank is unlocked or in SECURED state. Once set, it signals EAS alarm status to compatible readers without requiring backend database queries or additional hardware.
Can SL3S1205FUD2/HAPBZ be used with loop antennas?
Yes, SL3S1205FUD2/HAPBZ supports loop antenna designs because its RF1 and RF2 terminals allow DC connection between antenna ports. This configuration enables efficient magnetic coupling and broad bandwidth operation across 860–960 MHz, making it suitable for compact or metallic-environment deployments.
What distinguishes SL3S1205FUD2/HAPBZ from SL3S1205FUD2/HAP?
SL3S1205FUD2/HAPBZ uses conventional dicing on 12-inch wafers with 35 μm scribe line width, while SL3S1205FUD2/HAP uses plasma dicing with 6.6 μm scribe lines. Both share identical IC functionality, memory map, and RF specs-but HAPBZ is optimized for higher yield in standard label converter processes requiring robust dicing tolerance.
