Product details
Overview
RI-I16-112A from Texas Instruments is a passive HF RFID transponder inlay compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3, featuring 2 kbits user memory (64 × 32-bit blocks), 64-bit factory-programmed UID, and 13.56 MHz operating frequency - deployed in paper/plastic labels for library asset tracking and product authentication.
For engineers reviewing the RI-I16-112A datasheet, RI-I16-112A pinout, RI-I16-112A application, or RI-I16-112A equivalent, key selection criteria include required field strength (113 dBµA/m read / 116 dBµA/m write), aluminum antenna geometry (Ø24.2 mm), PET substrate compatibility, and simultaneous multi-tag identification up to 50 tags/sec.
Technical Context
The RI-I16-112A implements a fully passive, coil-coupled HF RFID architecture with integrated silicon die and planar aluminum antenna. It supports mandatory and optional ISO/IEC 15693 commands including Inventory, Read_Single_Block, Get_System_Info, and TI-custom Write_2_Blocks - all operating at 13.56 MHz carrier with 20%+ reader modulation depth recommended.
Memory is organized as 64 addressable 32-bit blocks (2048 bits user data), with dedicated DSFID/AFI registers, factory-programmed 64-bit UID, and lock bits per block (F/U) enabling hardware-level write protection. Resonance frequency is trimmed to 13.70 MHz ±400 kHz to compensate for lamination-induced detuning in paper or PVC substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz - standard HF RFID carrier; enables interoperability with commercial readers supporting ISO/IEC 15693. |
| Resonance Frequency | 13.70 MHz ±400 kHz - pre-compensated for dielectric loading during lamination into paper/PVC labels. |
| User Memory | 2 kbits (64 × 32-bit blocks) - sufficient for item-level serialization, batch ID, and tamper-evident flags. |
| UID Size | 64 bits factory-programmed - provides globally unique identifier without host-side assignment overhead. |
| Read Field Strength | 113 dBµA/m typical - defines minimum reader antenna field intensity needed for reliable communication at +25°C. |
| Write Endurance | 100,000 programming cycles - supports repeated re-labeling in reusable asset management systems. |
| Data Retention | >10 years at +55°C - ensures long-term validity of encoded data in warehouse or archival environments. |
Pinout & Package
RI-I16-112A is a passive RFID inlay with no electrical pins or terminals. It consists of a silicon IC die wire-bonded to a planar aluminum antenna on PET substrate. The device interfaces solely via electromagnetic coupling at 13.56 MHz; no physical connectors, solder pads, or discrete terminals are present.
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 15693-3 Compliance | Fully implements mandatory command set (Inventory, Read_Single_Block, Get_System_Info) and optional features (AFI/DSFID handling). |
| Factory-Programmed UID | 64-bit immutable identifier burned during wafer test - eliminates need for post-lamination encoding in high-speed label production. |
| Block-Level Locking | Dedicated F (factory) and U (user) lock bits per 32-bit block - enables selective write-protection of UID, configuration, or sensitive user data. |
| Lamination-Optimized Tuning | 13.70 MHz resonance with ±400 kHz margin - maintains functional range after embedding in paper or PVC without retuning. |
| Multi-Tag Identification | Supports up to 50 tags/sec anti-collision - enables rapid scanning of stacked or palletized goods in supply chain checkpoints. |
Applications
| Library Asset Tracking | Product Authentication |
|---|---|
Use Scenario: Embedding in book spines or media cases for automated check-in/out and shelf inventory reconciliation. IC Role / Device Role / Timing Role: Passive tag providing unique, unclonable UID and writable metadata blocks for circulation history.

IC Role / Device Role / Timing Role: Tamper-evident transponder storing cryptographic challenge-response seeds and batch traceability data. Use Value: Factory-lockable memory prevents unauthorized rewriting; UID+AFI+DSFID combination enables brand-specific reader filtering. |
| Supply Chain Pallet Tagging | Ticketing & Access Control |
Use Scenario: Laminated onto corrugated shipping containers or returnable transport items for warehouse receiving and cross-docking. IC Role / Device Role / Timing Role: High-density inlay supporting bulk-read operations under variable orientation and metal proximity. Use Value: 13.70 MHz tuning and aluminum antenna deliver consistent read range despite cardboard moisture and stacking interference. | Use Scenario: Embedded in event wristbands or transit smart cards for contactless entry validation. IC Role / Device Role / Timing Role: Low-power, fast-response transponder enabling sub-100ms verification at gate readers. Use Value: 100,000 write cycles support multi-event reuse; 64-bit UID ensures global uniqueness across venue-wide deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar passive HF RFID inlay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-I16-112B | Same die and memory structure; differs only in reel packaging (10,000 units/reel vs. 5,000 for RI-I16-112A). | No functional difference; intended for higher-volume automated label conversion lines. | Select RI-I16-112B when reel quantity aligns with converter's minimum order or tape feed requirements. |
| SL2 ICS20 | Infineon chip; same ISO/IEC 15693 compliance, 2 kbit memory, but uses copper antenna and different resonance tuning (13.56 MHz nominal). | Higher read sensitivity (105 dBµA/m) but less lamination tolerance; requires antenna redesign for paper integration. | Choose SL2 ICS20 only if existing reader infrastructure is optimized for lower field strength and substrate process allows copper etching. |
Compared with RI-I16-112A, RI-I16-112B offers identical RF performance with higher reel density, while SL2 ICS20 trades lamination robustness for marginally better read sensitivity - making RI-I16-112A optimal for high-yield paper/PVC label manufacturing where resonance stability post-lamination is critical.

FAQ
What is the operating temperature range for the RI-I16-112A?
The RI-I16-112A operates reliably from –25°C to +70°C. Its storage temperature range is –40°C to +85°C for single inlays (with potential warpage above +70°C), and –40°C to +40°C when supplied on reel. These ranges ensure functionality in warehouse, retail, and outdoor deployment environments where thermal cycling occurs.
Does the RI-I16-112A require a battery or external power source?
No, the RI-I16-112A is a fully passive transponder inlay. It derives all operating power from the RF magnetic field generated by an external reader antenna at 13.56 MHz - no onboard battery, capacitor, or energy-harvesting circuitry is included or required for RI-I16-112A operation.
How is memory organized in the RI-I16-112A?
The RI-I16-112A organizes its 2 kbits of user memory into 64 blocks of 32 bits each. Block 0 contains the 64-bit factory-programmed UID, followed by DSFID and AFI registers. Blocks 1–64 hold user-programmable data, with individual factory (F) and user (U) lock bits per block to enforce write protection in RI-I16-112A deployments.
Can the RI-I16-112A be used with ISO/IEC 14443 readers?
No, the RI-I16-112A is not compatible with ISO/IEC 14443 readers. It is strictly compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 standards - which define longer read ranges, different modulation schemes, and distinct command sets compared to ISO/IEC 14443. Using RI-I16-112A with 14443 readers will result in no communication.
What is the smallest bending radius allowed for the RI-I16-112A inlay?
The RI-I16-112A supports a minimum bending radius of 18 mm (∼0.71 in) without compromising antenna integrity or chip bond reliability. This specification enables conformal application on curved surfaces such as beverage bottles, cylindrical containers, or ergonomic wearable devices where mechanical flexing occurs during use or labeling.
