Product details
Overview
SL3S1215FUD2/HAPA from NXP Semiconductors is a UCODE 8m ultrahigh-frequency (UHF) RFID tag IC designed for global EPC Gen2v2 compliance, featuring -18 dBm write sensitivity, 96-bit pre-serialized EPC memory, 48-bit factory-locked unique serial number in TID, and integrated Product Status Flag (PSF) for electronic article surveillance. It enables long-read-distance inventory in retail and supply chain tagging with broadband antenna compatibility.
For engineers reviewing the SL3S1215FUD2/HAPA datasheet, SL3S1215FUD2/HAPA pinout, SL3S1215FUD2/HAPA application, or SL3S1215FUD2/HAPA equivalent, this page delivers verified technical context, exact die-level specifications, confirmed memory architecture, validated EPC Gen2v2 command support, and real-world deployment constraints for UHF RFID label design and mass production.
Technical Context

FAQ
What is the difference between SL3S1215FUD2/HAPA and SL3S1215FUD2/HAP?
The SL3S1215FUD2/HAPA uses conventional dicing on 12-inch wafers (35 μm scribe line), while SL3S1215FUD2/HAP uses plasma dicing (6.6 μm scribe line) and PE-oxide passivation. Both share identical UCODE 8m functionality, memory map, and EPC Gen2v2 command support. SL3S1215FUD2/HAPA is optimized for standard antenna lamination processes, whereas SL3S1215FUD2/HAP targets ultra-thin, high-yield flexible label production. SL3S1215FUD2/HAPA remains fully compatible with existing UCODE 8m firmware and reader ecosystems.
Does SL3S1215FUD2/HAPA support the Untraceable command per EPC Gen2v2?
Yes, SL3S1215FUD2/HAPA implements the Untraceable command as a defined optional feature per EPCglobal UHF Class 1 Generation 2 Version 2.0.1 specification. This command randomizes tag response patterns to prevent unauthorized tracking across multiple interrogation sessions. It operates without additional hardware or custom protocol extensions and is invoked using standard EPC ACCESS commands. The feature is enabled by default and requires no configuration word modification to function in SL3S1215FUD2/HAPA.
What memory banks are accessible on SL3S1215FUD2/HAPA and how is user data stored?
SL3S1215FUD2/HAPA provides four memory banks: Bank 00 (64-bit reserved, containing kill/access passwords), Bank 01 (96-bit EPC + 16-bit configuration word), Bank 10 (96-bit TID with factory-locked 48-bit serial number), and Bank 11 (32-bit user memory). User data is written to Bank 11 addresses 00h–1Fh. When Memory Safeguard is enabled via configuration word bit 20Ch, ECC protects this bank against single-bit errors. All banks support lock/permalock operations per EPC Gen2v2 rules, and SL3S1215FUD2/HAPA enforces permanent bit behavior for PSF and Self Adjust disable settings.
How is the Product Status Flag (PSF) implemented in SL3S1215FUD2/HAPA?
The Product Status Flag (PSF) in SL3S1215FUD2/HAPA is a permanent bit located at EPC memory address 20Fh. It is factory-initialized to "0" and can be toggled to "1" only via standard EPC WRITE command when the EPC bank is unlocked or in SECURED state. Once set, it remains active until the tag is killed. PSF enables standalone EAS functionality: readers detect the flag state directly without querying backend databases. SL3S1215FUD2/HAPA does not require external sensors or power sources-the PSF bit is read during standard inventory rounds and triggers alarm logic in compatible gate readers.
Can SL3S1215FUD2/HAPA be used with loop antennas?
Yes, SL3S1215FUD2/HAPA supports loop antenna designs due to its dual RF terminals (RF1 and RF2) and DC-coupled antenna interface architecture. The IC allows direct DC connection between RF1 and RF2, enabling efficient magnetic coupling in near-field dominant configurations. This capability is explicitly confirmed in Section 9.2 of the datasheet and validated across 860–960 MHz. Loop antenna use improves performance in metal-proximate or low-clearance labeling scenarios-common in retail shelf-edge and industrial asset tagging-without requiring matching networks or external components. SL3S1215FUD2/HAPA maintains full EPC Gen2v2 compliance in all supported antenna topologies.
