Product details
Overview
RI-TRP-R9WK-20 from Texas Instruments is a batteryless, read-only LF RFID transponder operating at 134.2 kHz using HDX (Half Duplex) transmission and FSK modulation (134.2/123.2 kHz). It provides 64-bit user memory in a single page, IP68-rated plastic wedge package (12 × 6 × 3 mm), and is designed for embedded animal identification and industrial asset tagging.
For engineers reviewing the RI-TRP-R9WK-20 datasheet, RI-TRP-R9WK-20 pinout, RI-TRP-R9WK-20 application, or RI-TRP-R9WK-20 equivalent, key selection factors include its HDX protocol compliance, 70 ms typical read time, -40°C to +85°C operating temperature range, IP68 environmental rating, and compatibility with TI's LF RFID reader ecosystems.
Technical Context
This transponder implements Half-Duplex (HDX) communication: the reader powers the device via magnetic coupling and initiates bidirectional data exchange by alternating between transmit and receive phases. It uses Frequency Shift Keying with two carrier frequencies-134.2 kHz for reader-to-transponder and 123.2 kHz for transponder-to-reader-ensuring robust demodulation in noisy environments.
The device draws power entirely from the reader's RF field (no onboard battery), supports up to 20 cm reading range under regulatory-compliant antenna configurations, and maintains data integrity across mechanical shock (200 g half-sine) and vibration (20 g, 1–500 Hz) per IEC 68-2 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - fixed carrier for reader-to-transponder link; defines magnetic coupling efficiency and regulatory compliance in LF ISM band. |
| Memory Capacity | 64 bits - single-page, read-only user memory; sufficient for unique ID encoding in animal ID and tool tracking. |
| Transmission Principle | HDX (Half Duplex) - eliminates simultaneous transmit/receive circuitry; enables ultra-low-power operation and deterministic timing. |
| Modulation | FSK (134.2 / 123.2 kHz) - dual-frequency shift ensures reliable backscatter decoding independent of amplitude variations. |
| Reading Range | ≤ 20 cm - achievable with compliant reader antennas and non-metallic mounting; limited by magnetic field decay and regulatory field strength caps. |
| Operating Temp (Read) | -40°C to +85°C - validated for continuous read operation in automotive under-hood, livestock ear tags, and outdoor industrial enclosures. |
| Protection Class | IP68 - fully dust-tight and submersible to 1 m for >30 min; enables direct embedment in epoxy, plastic housings, or animal implants. |
Pinout & Package
RI-TRP-R9WK-20 is a monolithic passive transponder with no external pins or terminals. It functions as a sealed, self-contained RF resonant circuit comprising an integrated coil antenna and ASIC die encapsulated in black plastic compound. The mechanical interface is defined solely by its wedge-shaped housing (12 mm × 6 mm × 3 mm ±0.05 mm).
Key Features
| Feature | Design Value |
|---|---|
| Batteryless Operation | Derives all power from reader's magnetic field - eliminates maintenance, leakage, and thermal derating concerns in sealed applications. |
| IP68 Encapsulation | Enables direct exposure to moisture, dust, and chemical washdowns without conformal coating or secondary housing. |
| HDX Protocol Compliance | Guarantees interoperability with ISO/IEC 11784/11785-compliant readers used in veterinary and livestock management systems. |
| Robust Mechanical Rating | Withstands 200 g shock and 20 g vibration - suitable for attachment to rotating machinery, vehicle chassis, or animal ear tags subject to impact. |
| Non-Metallic Signal Penetration | Reads reliably through plastic, rubber, wood, concrete, and biological tissue - supports implantable and embedded mounting. |
Applications
| Animal Identification | Industrial Tool Tracking |
|---|---|
Use Scenario: Permanent ear tag or injectable implant for cattle, sheep, or pets in automated feedlot or veterinary clinics. IC Role / Device Role / Timing Role: Passive transponder providing immutable 64-bit ID on demand; no timing or processing role - responds within 70 ms upon reader interrogation.

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 | 80-bit memory (64 user + 16-bit CRC), read/write capable, 309 ms programming time, -40°C to +70°C program temp limit | Supports field-updatable IDs and CRC-protected data; requires compatible write-enabled reader infrastructure | Select RI-TRP-W9WK only if dynamic ID assignment or tamper-evident checksums are required; RI-TRP-R9WK-20 remains optimal for static ID use cases. |
| EM4102 | 125 kHz, Manchester-encoded, read-only, 64-bit ROM, no HDX or FSK; smaller TO-92-like capsule (8.5 × 2.5 mm) | Limited to legacy 125 kHz readers; lacks IP68 rating and mechanical ruggedness; unsuitable for wet or high-shock environments | Choose EM4102 only for cost-sensitive, low-ruggedness indoor access cards; RI-TRP-R9WK-20 delivers superior environmental resilience and ISO 11785 alignment. |
Compared with RI-TRP-W9WK and EM4102, RI-TRP-R9WK-20 uniquely balances ISO-compliant HDX operation, full IP68 sealing, and wide-temperature read functionality - making it the preferred choice for mission-critical animal ID and industrial asset tagging where reliability outweighs reprogrammability.

FAQ
What is the operating frequency of the RI-TRP-R9WK-20?
The RI-TRP-R9WK-20 operates at 134.2 kHz for reader-to-transponder communication and uses 123.2 kHz for transponder-to-reader backscatter, implementing FSK modulation within the LF ISM band. This dual-frequency HDX scheme ensures regulatory compliance and noise immunity in industrial and veterinary settings where the RI-TRP-R9WK-20 is deployed.
Does the RI-TRP-R9WK-20 require a battery?
No, the RI-TRP-R9WK-20 is a fully passive transponder that derives all operating power from the magnetic field generated by a compatible LF RFID reader. Its batteryless design eliminates maintenance, leakage risk, and temperature-related capacity loss - a core requirement for permanent implantation and embedded industrial tagging using the RI-TRP-R9WK-20.
What is the maximum reading range for the RI-TRP-R9WK-20?
The typical reading range of the RI-TRP-R9WK-20 is ≤20 cm, dependent on reader antenna configuration, local RF regulations, and environmental conditions such as nearby metal or moisture. This range is validated under ISO/IEC 11785-compliant test setups and represents the practical limit for reliable HDX interrogation of the RI-TRP-R9WK-20 in real-world deployments.
Is the RI-TRP-R9WK-20 suitable for use in wet or dusty environments?
Yes, the RI-TRP-R9WK-20 carries an IP68 ingress protection rating, confirming full dust-tightness and submersion capability up to 1 meter for over 30 minutes. This makes it suitable for direct installation in washdown zones, outdoor livestock facilities, and enclosed industrial equipment where the RI-TRP-R9WK-20 must maintain functionality despite persistent exposure to moisture and particulates.
Can the RI-TRP-R9WK-20 be programmed after deployment?
No, the RI-TRP-R9WK-20 is a read-only transponder with factory-programmed 64-bit memory. It does not support field reprogramming. For applications requiring writable memory, TI offers the RI-TRP-W9WK variant - but the RI-TRP-R9WK-20 is optimized for permanent, tamper-proof identification where data immutability is essential.
