Product details
Overview
RI-I11-114A-S1 from Texas Instruments is a passive 13.56 MHz HF RFID transponder inlay compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 standards, featuring a 45 mm × 45 mm aluminum antenna on PET foil, factory-programmed 64-bit UID, and 256-bit user EEPROM organized in eight 32-bit lockable blocks - deployed in paper-based smart labels for asset tagging and electronic ticketing.
For engineers reviewing the RI-I11-114A-S1 datasheet, RI-I11-114A-S1 pinout, RI-I11-114A-S1 application, or RI-I11-114A-S1 equivalent, this inlay's frequency offset (13.86 MHz ± 200 kHz) is specifically tuned for optimal resonance after integration into paper substrates, and its activation field strength (98 dBµA/m typical read, 101 dBµA/m typical write) defines minimum reader power requirements in label-conversion environments.
Technical Context
The RI-I11-114A-S1 implements full-duplex ASK/FSK subcarrier modulation per ISO/IEC 15693, supporting both 1-out-of-4 and 1-out-of-256 downlink coding and high/low data rate uplink modes. Its laser-trimmed aluminum capacitor compensates process and material tolerances to maintain target resonance post-lamination.
It features collision-resistant anticollision via UID-based inventory commands, password-protected WriteSingleBlockPwd (0xA5), and factory-locked UID blocks (0x00–0x01). Memory is nonvolatile EEPROM rated for 100,000 programming cycles and >10 years data retention at 55°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.86 MHz ± 200 kHz - frequency offset pre-tuned for minimal detuning after lamination into paper substrates. |
| Antenna Dimensions | 45 mm × 45 mm - square aluminum antenna geometry optimized for balanced read range and orientation tolerance in label formats. |
| Read Field Strength | 98 dBµA/m typical - minimum magnetic field intensity required at 25°C for reliable block reads in paper-integrated labels. |
| User Memory | 256 bits (8 × 32-bit blocks) - field-programmable EEPROM with individual block locking and password-protected rewrites. |

Pinout & Package
RI-I11-114A-S1 is a passive RFID inlay with no electrical pins or terminals. It consists of a flip-chip mounted IC electrically coupled to an integrated aluminum antenna etched on both sides of a 0.085 mm PET substrate. The device has no leads, pads, or solderable interfaces - connection is exclusively via electromagnetic coupling to a 13.56 MHz reader antenna.
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed capacitor | Individually tuned resonance ensures consistent 13.86 MHz operation across all units after paper lamination. |
| Factory-locked UID | 64-bit read-only identifier prevents cloning and enables deterministic one-to-one communication in dense tag fields. |
| Per-block memory lock | Each 32-bit user block can be independently write-locked; locked blocks require password (0xA5) for modification. |
| ISO/IEC 15693 compliance | Supports mandatory inventory, read/write/lock commands and optional AFI - interoperable with global HF readers. |
| Paper-optimized frequency offset | 13.86 MHz center frequency compensates dielectric loading from cellulose fibers, maintaining read range post-conversion. |
Applications
| Asset Tracking Labels | Electronic Transit Tickets |
|---|---|
Use Scenario: Paper-based labels affixed to IT equipment, medical devices, or library books for automated check-in/out and lifecycle logging. IC Role / Device Role / Timing Role: Passive transponder providing secure, battery-free identification and field-updatable status metadata. Use Value: 256-bit user memory stores asset ID, calibration date, and maintenance history; UID enables unambiguous database linking without manual entry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HF RFID inlay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-I11-114B-S1 | Resonance frequency 14.4 MHz ± 200 kHz - tuned for PVC lamination, not paper. | Optimized for rigid plastic badges or laminated ID cards, not flexible paper labels. | Select RI-I11-114B-S1 only when integrating into PVC or polycarbonate substrates where dielectric constant differs significantly from paper. |
| RI-I02-114A-S1 | Rectangular 45 mm × 76 mm antenna; same 13.86 MHz offset and paper optimization. | Provides longer read range in linear orientation; suited for pallet tags or elongated product packaging. | Choose RI-I02-114A-S1 when label format requires directional read performance or larger surface area for adhesive bonding. |
Compared with RI-I11-114A-S1, RI-I11-114B-S1 shifts resonance for PVC compatibility - risking 3–5 dB read loss in paper - while RI-I02-114A-S1 retains identical frequency tuning but extends antenna length to improve linear-range sensitivity at the cost of square-format footprint compatibility.

FAQ
What is the purpose of the frequency offset in RI-I11-114A-S1?
The 13.86 MHz ± 200 kHz resonance frequency of RI-I11-114A-S1 is intentionally offset to compensate for detuning caused by the dielectric properties of paper substrates during lamination. This ensures the inlay maintains optimal coupling efficiency and read range after final label assembly - a critical design feature confirmed in TI's SCBU009B specification tables for RI-I11-114A-S1.
Does RI-I11-114A-S1 have electrical pins or solderable terminals?
No, RI-I11-114A-S1 is a fully passive RFID inlay with no pins, pads, or electrical contacts. It operates solely through electromagnetic induction between its integrated aluminum antenna and a 13.56 MHz reader coil. The device contains no interface circuitry beyond the flip-chip mounted IC and resonant LC structure defined in Figure 1-2 of the TI reference guide.
Can RI-I11-114A-S1 be used in PVC-based badges?
RI-I11-114A-S1 is explicitly tuned for paper integration and will exhibit suboptimal resonance - typically reduced read range and higher required field strength - when laminated into PVC. For PVC applications, TI specifies RI-I11-114B-S1 (14.4 MHz ± 200 kHz) as the correct variant, as documented in Table 2-2 of SCBU009B.
How is memory protected on RI-I11-114A-S1?
RI-I11-114A-S1 provides two-tier memory protection: (1) individual 32-bit blocks can be permanently locked via Lock_Block (0x22), preventing further writes; (2) locked blocks may be rewritten only using the password-protected WriteSingleBlockPwd command (0xA5), which requires knowledge of the stored 6-byte password. Both mechanisms are implemented in silicon and verified in TI's memory organization diagram (Figure 1-3).
What is the maximum number of RI-I11-114A-S1 inlays a reader can identify simultaneously?
RI-I11-114A-S1 supports ISO/IEC 15693 anticollision protocols enabling up to 50 tags per second identification throughput - dependent on reader hardware, antenna design, and field uniformity. This capability is enabled by its factory-programmed 64-bit UID and standardized inventory command set (0x01), as specified in Table 1-1 and Section 1.4 of the TI reference guide.
