Product details
Overview
RI-TRP-W9WK-20 from Texas Instruments is a batteryless, read/write LF RFID transponder operating at 134.2 kHz with HDX (Half Duplex) transmission, 80-bit memory (64 user + 16-bit CRC), IP68 rating, and 12 mm × 6 mm × 3 mm wedge-shaped plastic package - used in industrial asset tagging and animal identification systems.
For engineers reviewing the RI-TRP-W9WK-20 datasheet, RI-TRP-W9WK-20 pinout, RI-TRP-W9WK-20 application, or RI-TRP-W9WK-20 equivalent, key selection factors include its HDX modulation scheme, 309 ms typical programming time, -40°C to +70°C programming temperature range, 100,000-programming-cycle endurance, and non-metallic material signal penetration capability.
Technical Context
The RI-TRP-W9WK-20 implements HDX (Half Duplex) communication: the reader supplies power via magnetic field coupling, then pauses to allow the transponder to transmit its response using FSK modulation between 134.2 kHz and 123.2 kHz. It requires no internal power source and draws energy solely from the reader's RF field.
Memory is organized as one 80-bit page, with TI recommending 64 bits for user data and 16 bits reserved for CCITT CRC - enforced by TI-RFID LF readers. Programming is supported only within -40°C to +70°C, while read operation extends to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - defines resonant coupling frequency with reader antenna; mandates matching inductor-capacitor tuning. |
| Memory Capacity | 80 bits (1 page) - supports 64 user bits + 16-bit CCITT CRC; fixed single-page architecture limits data segmentation. |
| Transmission Principle | HDX (Half Duplex) - requires precise reader timing control; reader powers device, then pauses for transponder reply. |
| Modulation | FSK (134.2 / 123.2 kHz) - enables robust demodulation in noisy industrial environments without requiring complex receiver circuitry. |
| Reading Range | ≤ 20 cm - highly dependent on reader antenna size, coil geometry, and local RF regulations; not guaranteed in metal-rich environments. |
| Programming Cycles | 100,000 - specifies maximum write endurance before bit error rate exceeds specification; critical for reusable tag applications. |
| Operating Temp (Program) | -40°C to +70°C - narrower than read range; programming must be suspended above +70°C to prevent memory corruption. |
Pinout & Package
RI-TRP-W9WK-20 is a fully encapsulated, passive RFID transponder with no external electrical terminals or pins. It contains an integrated ferrite-core coil antenna and EEPROM, housed in a black plastic wedge package measuring 12 mm × 6 mm × 3 mm ±0.05 mm. No PCB mounting or soldering is required - it operates via inductive coupling only.
Key Features
| Feature | Design Value |
|---|---|
| Batteryless HDX Operation | Enables maintenance-free deployment in sealed or embedded environments where battery replacement is impractical or prohibited. |
| IP68 Encapsulation | Guarantees full dust ingress protection and continuous submersion in water up to 1 m for 30 minutes - suitable for washdown and outdoor asset tracking. |
| Non-Metallic Signal Penetration | Allows reliable reading through plastic, rubber, wood, concrete, and biological tissue - enabling implantable and embedded tagging. |
| EMI/X-ray Immunity | Preserves programmed data integrity during exposure to industrial EMI sources and medical/industrial X-ray inspection equipment. |
| Robust Mechanical Rating | Withstands 200 g shock (IEC 68-2-27) and 20 g vibration (IEC 68-2-6), supporting use in transportation, logistics, and heavy machinery. |
Applications
| Animal Identification | Industrial Asset Tagging |
|---|---|
Use Scenario: Subcutaneous implantation in livestock for lifetime traceability across farms, slaughterhouses, and export checkpoints. IC Role / Device Role / Timing Role: Passive read/write transponder storing ISO-compliant ID and health records; responds only when energized by handheld or portal reader. Use Value: Eliminates need for batteries or external power; IP68 and mechanical ruggedness ensure survival under physiological stress and repeated handling. | Use Scenario: Mounting inside metal-housed valves, pumps, or motors in oil & gas facilities for maintenance logging and calibration history. IC Role / Device Role / Timing Role: Read/write data carrier interfacing exclusively with TI-compatible LF readers; stores serial number, service date, and firmware version.

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-W9WK-10 | Same die and memory structure; differs only in wedge geometry - 10 mm length vs. 12 mm for W9WK-20. | Preferred where space-constrained mounting (e.g., narrow-diameter syringes or dental tools) requires shorter form factor. | Select W9WK-10 when mechanical envelope is tighter; verify antenna coupling efficiency remains sufficient at reduced coil area. |
| RI-TRP-W9WK-30 | Identical electrical specs and memory map; features extended 15 mm length for higher read range in low-coupling scenarios. | Suitable for large-diameter assets (e.g., pipeline flanges, transformer bushings) where increased coil inductance improves link budget. | Choose W9WK-30 when ≥25 cm read distance is required under same reader conditions; confirm mechanical fit in host assembly. |
Compared with RI-TRP-W9WK-10 and RI-TRP-W9WK-30, the RI-TRP-W9WK-20 offers the balanced trade-off of mechanical robustness, coupling efficiency, and compactness - making it the default choice for general-purpose industrial and animal ID deployments where standardized 12 mm wedge integration is specified.

FAQ
What is the memory organization of the RI-TRP-W9WK-20?
The RI-TRP-W9WK-20 contains a single 80-bit memory page. Texas Instruments recommends allocating 64 bits for user data and reserving the remaining 16 bits for a CCITT CRC block check character - a requirement enforced by TI-RFID LF readers to ensure data integrity during programming and verification cycles of the RI-TRP-W9WK-20.
Does the RI-TRP-W9WK-20 require a battery or external power source?
No, the RI-TRP-W9WK-20 is a fully passive transponder. It derives all operating power from the magnetic field generated by a compatible LF reader via inductive coupling. Its batteryless design eliminates maintenance, leakage risk, and temperature-related failure modes - a core reliability feature of the RI-TRP-W9WK-20.
What is the maximum operating temperature for programming the RI-TRP-W9WK-20?
The RI-TRP-W9WK-20 supports programming only within -40°C to +70°C. While read operations function up to +85°C, programming above +70°C risks EEPROM corruption. This thermal limitation is documented in TI's official datasheet for the RI-TRP-W9WK-20 and must be respected in sterilization or engine-bay deployment scenarios.
Can the RI-TRP-W9WK-20 be read through metal?
No - the RI-TRP-W9WK-20 cannot be reliably read through metal. Its 134.2 kHz magnetic coupling is disrupted by conductive materials. However, TI confirms the RI-TRP-W9WK-20 can be read through virtually all non-metallic substances including plastic, rubber, concrete, and biological tissue, as verified in TI's signal penetration testing for the RI-TRP-W9WK-20.
What mechanical standards does the RI-TRP-W9WK-20 meet for shock and vibration?
The RI-TRP-W9WK-20 complies with IEC 68-2-27 (200 g, half-sine, 3 ms, 3 axes) for shock and IEC 68-2-6 (20 g, 1–500 Hz, 3 axes, 24 hours/axis) for vibration. These validated ratings ensure operational integrity in high-dynamic environments such as vehicle-mounted asset tracking and rotating machinery monitoring - confirmed in TI's qualification report for the RI-TRP-W9WK-20.
