Product details
Overview
RI-TRP-W9TD-30 from Texas Instruments is a 134.2 kHz ISO 11784/11785–compliant LF RFID transponder with HDX (Half-Duplex) modulation, 80-bit read/write memory, IP67-rated reinforced poly-ether-imide (PEI) cylindrical housing (Ø21 mm × 121 mm), and operating temperature range of –25°C to +70°C. It is batteryless, powered by reader field, and used in vehicle identification and container tracking systems requiring robust non-metallic material penetration.
For engineers reviewing the RI-TRP-W9TD-30 datasheet, RI-TRP-W9TD-30 pinout, RI-TRP-W9TD-30 application, or RI-TRP-W9TD-30 equivalent, key selection considerations include HDX protocol compliance, 80-bit programmable memory architecture, 134.2 kHz resonance, IP67 mechanical robustness, and TI's patented tuning process for stable read/write performance across varying environmental conditions.
Technical Context
The RI-TRP-W9TD-30 implements Half-Duplex (HDX) communication using Frequency Shift Keying (FSK) at 134.2 kHz (carrier) and 123.2 kHz (subcarrier), enabling simultaneous energy harvesting and bidirectional data exchange. Its tuned LC resonator is factory-calibrated via TI's patented process to maintain consistent impedance matching and coupling efficiency.
It operates without an internal power source, drawing energy exclusively from the reader's magnetic field, and supports up to 100,000 programming cycles with CRC-protected 80-bit memory-structured as one page containing 64 user bits plus 16-bit CCITT CRC-ensuring data integrity during over-the-air writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - defines magnetic coupling bandwidth and regulatory compliance with ISO 11784/11785 LF RFID standards |
| Memory Capacity | 80-bit read/write - supports one page with 64 user bits + 16-bit CCITT CRC for error detection in field-programmed data |
| Modulation Scheme | FSK (134.2 / 123.2 kHz) - enables reliable demodulation under low-SNR conditions typical in metal-adjacent or high-noise industrial environments |
| Reading Range | ≤200 cm - maximum achievable distance under optimal reader antenna configuration and regulatory limits (e.g., ETSI EN 300 330) |
| Programming Range | 30% of reading range - ~60 cm max under same conditions, reflecting reduced field strength required for write operations |
| Environmental Rating | IP67 - ensures full dust ingress protection and immersion resistance up to 1 m for 30 minutes, suitable for outdoor and harsh industrial deployment |
| Operating Temperature | –25°C to +70°C - validated functional range for continuous operation in automotive under-hood, waste management, and logistics applications |
Pinout & Package
RI-TRP-W9TD-30 is a passive, two-terminal (coil-only) cylindrical transponder with no electrical pins or solderable terminals. Its RF interface consists solely of an integrated, factory-tuned LC resonator coil embedded within the Ø21 mm × 121 mm PEI housing. No external connections are required or supported.
Key Features
| Feature | Design Value |
|---|---|
| Patented Tuning Process | Factory-calibrated LC resonance ensures consistent read/write performance across production lots and temperature gradients |
| HDX Protocol Compliance | Full adherence to ISO 11784/11785 HDX mode enables interoperability with global LF RFID readers and infrastructure |
| Batteryless Operation | Zero-power design eliminates maintenance, leakage, and lifetime limitations-ideal for sealed, long-life asset tagging |
| Non-Metallic Penetration | Operates reliably through wood, plastic, concrete, soil, and water-enabling embedding in tires, containers, and structural components |
| EMI/X-ray Immunity | Programmed data remains intact under normal electromagnetic interference and medical/industrial X-ray exposure |
Applications
| Vehicle Identification | Container Tracking |
|---|---|

IC Role / Device Role / Timing Role: Field-programmable 80-bit tag storing serial number, calibration date, and service records. Use Value: CRC-protected memory prevents corruption during repeated updates in electrically noisy job sites with heavy machinery EMI. | Use Scenario: Embedded in underground waste bins to log fill-level, collection frequency, and route optimization data. IC Role / Device Role / Timing Role: Batteryless tag powered by handheld reader during municipal collection rounds. Use Value: –25°C to +70°C operation and shock/vibration resistance (IEC 68-2-27/6) ensure reliability in freeze-thaw cycles and compaction stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-D9TD-30 | Read-only functionality; 64-bit memory; identical package and operating temperature (–25°C to +70°C) | Lacks field-programmability; suitable only for static ID applications like animal tagging or access cards | Select RI-TRP-D9TD-30 when write capability is unnecessary and cost minimization is prioritized |
| EM4102 (from EM Microelectronic) | Read-only; 128-bit memory; 125 kHz carrier; proprietary protocol (not ISO 11784/11785 compliant) | Requires custom reader firmware; limited to legacy or proprietary systems not requiring global standardization | Choose EM4102 only for brownfield installations where existing 125 kHz infrastructure cannot be upgraded |
Compared with RI-TRP-D9TD-30 and EM4102, the RI-TRP-W9TD-30 uniquely delivers ISO-compliant HDX read/write capability at 134.2 kHz in an IP67-rated cylindrical form-making it the only option among the three qualified for dynamic, standards-based industrial asset tracking with field-updatable data.

FAQ
What is the memory structure of the RI-TRP-W9TD-30?
The RI-TRP-W9TD-30 contains 80 bits of read/write memory organized as a single page. TI recommends allocating 64 bits for user data and 16 bits for a CCITT CRC block check character to ensure data integrity during wireless programming. This structure is fixed and not partitionable into multiple pages.
Is the RI-TRP-W9TD-30 compatible with ISO 11784/11785 readers?
Yes, the RI-TRP-W9TD-30 is fully compliant with ISO/IEC 11784 and 11785 standards for HDX (Half-Duplex) LF RFID transponders. It uses FSK modulation at 134.2 kHz and meets all protocol timing, encoding, and air-interface requirements specified in those standards.
What is the maximum operating temperature for the RI-TRP-W9TD-30?
The RI-TRP-W9TD-30 is rated for continuous operation from –25°C to +70°C. This range is validated per TI's production testing and supports deployment in demanding environments such as vehicle under-hood locations, outdoor container yards, and waste collection vehicles exposed to solar heating.
Does the RI-TRP-W9TD-30 require a battery or external power source?
No, the RI-TRP-W9TD-30 is a fully passive transponder. It derives all operating power from the magnetic field generated by a compatible ISO 11784/11785 reader antenna-no battery, capacitor, or external power connection is needed or supported.
Can the RI-TRP-W9TD-30 be embedded inside metallic enclosures?
No-the RI-TRP-W9TD-30 cannot operate when enclosed by or in direct contact with conductive metals, as they detune the LC resonator and shield the magnetic field. It is designed for use behind or within non-metallic materials (e.g., plastic, rubber, concrete) where signal penetration is maintained.
