Texas Instruments RI-TRP-R9TD-16

Overview

RI-TRP-R9TD from Texas Instruments is a 134.2 kHz ISO 11784/11785-compliant LF RFID transponder in a 120 mm cylindrical form factor, featuring 64-bit read-only memory, HDX (Half-Duplex) transmission, and IP67-rated reinforced poly-ether-imide housing. It operates batterylessly, delivers ≤200 cm typical read range, and is deployed in vehicle identification and container tracking systems requiring robust non-metallic material penetration.

For engineers reviewing the RI-TRP-R9TD datasheet, RI-TRP-R9TD pinout, RI-TRP-R9TD application, or RI-TRP-R9TD equivalent, key selection considerations include its HDX modulation scheme, 64-bit read-only memory architecture, ISO 11784/11785 compliance, operating temperature range (–25°C to +85°C), and IP67 environmental rating for industrial asset management deployments.

Technical Context

The RI-TRP-R9TD implements Half-Duplex (HDX) communication at 134.2 kHz with FSK modulation (134.2 / 123.2 kHz), enabling reliable backscatter-based data exchange without an internal power source. Its patented tuning process ensures stable resonance and consistent read performance across varying coupling conditions.

Designed for passive operation, the transponder draws energy solely from the reader's magnetic field and supports deterministic timing: 70 ms typical read time, immunity to x-ray and standard EMC environments, and mechanical robustness per IEC 68-2-27 (200 g shock) and IEC 68-2-6 (20 g vibration).

FAQ

What is the operating frequency and modulation type of the RI-TRP-R9TD-16?

The RI-TRP-R9TD-16 operates at a fixed 134.2 kHz carrier frequency using Frequency Shift Keying (FSK) modulation with HDX (Half-Duplex) transmission. This enables robust communication in noisy electromagnetic environments and ensures compatibility with ISO 11784/11785-compliant readers. Its resonance is stabilized by TI's patented tuning process, and no external clock or configuration is required for basic read operation.

Is the RI-TRP-R9TD-16 suitable for outdoor or harsh environmental use?

Yes, the RI-TRP-R9TD-16 is rated IP67 and constructed from reinforced poly-ether-imide (PEI), making it resistant to dust, water immersion up to 1 m for 30 minutes, mechanical shock (200 g), and vibration. Its –25°C to +85°C operating temperature range supports deployment in vehicle underbodies, waste collection systems, and unconditioned logistics infrastructure where the RI-TRP-R9TD-16 must function reliably over extended service life.

Does the RI-TRP-R9TD-16 require a battery or external power source?

No, the RI-TRP-R9TD-16 is a fully passive transponder that derives all operating power from the magnetic field generated by an external LF reader antenna. It contains no battery, eliminating maintenance, replacement, and end-of-life disposal concerns. This design makes the RI-TRP-R9TD-16 ideal for permanent installations where service access is impractical or cost-prohibitive.

What memory configuration does the RI-TRP-R9TD-16 support?

The RI-TRP-R9TD-16 provides 64 bits of factory-programmed, read-only memory structured per ISO 11784 for animal and asset identification. It does not support field programming or rewriting. Data retention is permanent and unaffected by x-rays, standard EMC exposure, or environmental aging-ensuring the RI-TRP-R9TD-16 maintains its assigned ID throughout its operational lifetime.

Is the RI-TRP-R9TD-16 compliant with international RFID standards?

Yes, the RI-TRP-R9TD-16 is fully compliant with ISO/IEC 11784 and ISO/IEC 11785 standards for low-frequency RFID systems. This guarantees interoperability with certified readers used in global livestock management, vehicle access control, and container logistics. Compliance was verified through TI's functional and parametric testing prior to shipment, confirming the RI-TRP-R9TD-16 meets all mandatory protocol, timing, and signal integrity requirements.
