Texas Instruments RI-TRP-W9TD-13

Overview

RI-TRP-W9TD-13 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 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-13 datasheet, RI-TRP-W9TD-13 pinout, RI-TRP-W9TD-13 application, or RI-TRP-W9TD-13 equivalent, key selection criteria include HDX protocol compliance, 80-bit programmable memory architecture, 134.2 kHz resonance frequency, IP67 mechanical robustness, and TI's patented tuning process for stable read/write performance across varying environmental conditions.

Technical Context

The RI-TRP-W9TD-13 implements Half-Duplex (HDX) communication using FSK modulation at 134.2 kHz (carrier) and 123.2 kHz (shift), enabling simultaneous power harvesting and data exchange with compatible readers. Its tuned LC circuit operates without onboard power, relying entirely on magnetic coupling from the reader antenna.

It supports 80-bit user-programmable memory organized in one page, with TI recommending 64 bits for data and 16 bits for CCITT CRC checksum. Programming endurance is rated at 100,000 cycles, and typical programming time is 309 ms at ≤30% of reading range (≤60 cm under optimal conditions).

Key Specifications

Pinout & Package

This is a passive, two-terminal resonant transponder with no electrical pins or solderable terminals. Power and data are coupled wirelessly via its internal coil and capacitor network. The device is housed in a sealed, cylindrical reinforced poly-ether-imide (PEI) case (Ø21 mm ± 0.8 mm × 121 mm ± 2 mm), black in color, with no external connectors or leads.

FAQ

What is the memory structure of the RI-TRP-W9TD-13?

The RI-TRP-W9TD-13 contains 80 bits of read/write memory organized in a single page. Texas Instruments recommends allocating 64 bits for user data and 16 bits for a CCITT CRC checksum to ensure data integrity during transmission and storage. This structure is fixed and not partitionable into multiple pages or sectors.

Is the RI-TRP-W9TD-13 compatible with ISO 11784/11785 readers?

Yes, the RI-TRP-W9TD-13 is fully compliant with ISO/IEC 11784 and ISO/IEC 11785 standards for low-frequency RFID transponders. It uses HDX (Half-Duplex) protocol and 134.2 kHz carrier frequency, ensuring interoperability with certified readers deployed in animal identification, vehicle access, and container tracking systems worldwide.

What is the maximum operating temperature for the RI-TRP-W9TD-13?

The RI-TRP-W9TD-13 is rated for continuous operation from –25°C to +70°C. This specification is validated across functional and parametric testing per the SCBS838 datasheet. Operation outside this range may result in reduced read range, programming failure, or irreversible memory corruption.

Does the RI-TRP-W9TD-13 require a battery or external power source?

No, the RI-TRP-W9TD-13 is a fully passive transponder. It derives all operating power from the magnetic field generated by a compatible HDX reader antenna. There is no internal battery, no charging circuitry, and no external power connection - enabling maintenance-free, multi-decade deployment in sealed environments.

What mechanical certifications does the RI-TRP-W9TD-13 meet?

The RI-TRP-W9TD-13 meets IP67 ingress protection, IEC 68-2-27 mechanical shock (200 g, half-sine, 3 ms), and IEC 68-2-6 vibration (20 g, 20–500 Hz). These certifications validate its suitability for mounting on vehicles, embedding in containers, and deployment in municipal waste infrastructure subject to impact and motion stress.
