Product details
Overview
RI-TRP-W9UR from Texas Instruments is an ISO 11784/11785-compliant, batteryless 134.2 kHz HDX RFID transponder disk with 80-bit read/write memory, IP53-rated ASA housing, and operating temperature range of –25°C to +70°C. It delivers stable read/write performance in vehicle identification, container tracking, and asset management systems.
For engineers reviewing the RI-TRP-W9UR datasheet, RI-TRP-W9UR pinout, RI-TRP-W9UR application, or RI-TRP-W9UR equivalent, key selection criteria include HDX modulation support, 30% programming range relative to reading range, 100,000 write cycles, FSK transmission at 134.2/123.2 kHz, and mechanical robustness per IEC 68-2-27/6.
Technical Context
The RI-TRP-W9UR implements Half-Duplex (HDX) communication using Frequency Shift Keying (FSK) at 134.2 kHz (carrier) and 123.2 kHz (subcarrier), enabling reliable bidirectional data exchange without onboard power. Its patented tuning process ensures consistent coupling efficiency across non-metallic media.
It operates exclusively in passive mode-powered solely by the reader's magnetic field-and supports a single 80-bit memory page with CRC-CCITT block check character implementation recommended for error detection. Memory is organized as 64 user-programmable bits plus 16-bit CRC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - defines resonant coupling frequency with reader antenna; determines regulatory compliance scope (e.g., EU ERP, FCC Part 15) |
| Memory Capacity | 80 bits (1 page) - enables storage of extended ID, status flags, or maintenance logs; requires CRC partitioning per TI-RFid™LF readers |
| Read/Write Capability | Read/Write - supports field-updatable data such as service history or ownership transfer without physical replacement |
| Reading Range | ≤150 cm - maximum usable distance under optimal conditions (reader antenna design, regulation, environment) |
| Programming Cycles | 100,000 - specifies endurance limit for repeated field reprogramming; critical for long-life asset tagging |
| Protection Class | IP53 - dust-protected and resistant to water spray at angles up to 60°; suitable for outdoor industrial enclosures |
| Operating Temp | –25°C to +70°C - narrower than RI-TRP-R9UR (–25°C to +85°C); constrains deployment in high-ambient engine bays or solar-exposed containers |
Pinout & Package
RI-TRP-W9UR is a monolithic, encapsulated RFID transponder disk with no external electrical terminals or pins. It contains an integrated coil antenna and tuned LC circuit housed in an acrylate-styrene-acrylonitrile (ASA) black plastic case. No pinout table applies.
Key Features
| Feature | Design Value |
|---|---|
| Patented Transponder Tuning | Ensures consistent read/write coupling efficiency across varying mounting substrates (plastic, wood, concrete) without manual calibration |
| HDX Transmission Principle | Enables full-duplex-like operation over a single carrier frequency by time-multiplexing reader transmit and transponder reply phases |
| ISO 11784/11785 Compliance | Guarantees interoperability with globally standardized LF RFID readers used in livestock, vehicle, and logistics infrastructure |
| Insensitive to Non-Metallic Materials | Permits embedding within plastic housings, rubber tires, or composite panels without signal attenuation or detuning |
| EMI/X-ray Immunity | Preserves programmed data integrity during exposure to electromagnetic interference or medical/industrial X-ray inspection processes |
Applications
| Vehicle Identification | Container Tracking |
|---|---|
Use Scenario: Mounted on chassis or undercarriage for automated tolling, fleet gate access, or VIN verification in wash bays. IC Role / Device Role / Timing Role: Passive identity token providing tamper-resistant, battery-free identification via HDX handshake.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-R9UR | 64-bit read-only memory; wider operating temperature (–25°C to +85°C); same HDX/FSK protocol and dimensions | Suitable where data immutability is required (e.g., permanent VIN tags); not usable for field-updated records | Select RI-TRP-R9UR when write capability is unnecessary and higher ambient temperature tolerance is needed. |
| EM4102 (from EM Microelectronic) | Read-only 128-bit UID; operates at 125 kHz; no HDX or FSK; uses Manchester encoding; smaller form factor (Ø30 mm) | Used in legacy access control systems; lacks ISO 11784/11785 compliance and environmental ruggedness | Select EM4102 only for cost-sensitive, low-complexity read-only deployments with existing 125 kHz infrastructure. |
Compared with RI-TRP-R9UR and EM4102, the RI-TRP-W9UR uniquely combines ISO-compliant HDX read/write functionality, 80-bit programmable memory, and IP53-rated mechanical durability-making it the only option among the three qualified for reusable container tracking and field-serviceable asset tagging.

FAQ
What is the memory structure of the RI-TRP-W9UR?
The RI-TRP-W9UR contains a single 80-bit memory page. Texas Instruments recommends partitioning this into 64 user-programmable bits and a 16-bit CRC CCITT Block Check Character for error detection. This layout ensures data integrity during field programming and is optimized for use with TI-RFid™LF readers.
Does the RI-TRP-W9UR require a battery?
No, the RI-TRP-W9UR is a fully passive transponder powered solely by the magnetic field generated by the reader antenna. It contains no internal battery or energy storage, enabling maintenance-free operation over its entire service life-critical for sealed or inaccessible installations.
What is the maximum operating temperature for the RI-TRP-W9UR?
The RI-TRP-W9UR has a specified operating temperature range of –25°C to +70°C. This is 15°C narrower than the RI-TRP-R9UR variant (+85°C max), making it unsuitable for under-hood automotive applications but well-suited for exterior-mounted container or waste bin use where ambient extremes are moderated.
Is the RI-TRP-W9UR compliant with international RFID standards?
Yes, the RI-TRP-W9UR is fully compliant with ISO/IEC 11784 and ISO/IEC 11785 standards for low-frequency RFID systems. This ensures interoperability with certified readers deployed globally in livestock management, vehicle access, and logistics infrastructure.
How does the patented tuning process improve RI-TRP-W9UR performance?
The patented tuning process applied to the RI-TRP-W9UR ensures precise LC resonance matching at 134.2 kHz across production units, minimizing unit-to-unit variation in read/write range and coupling efficiency-even when mounted behind non-metallic materials like plastic, rubber, or concrete.
