Texas Instruments RI-TRP-R9UR

Overview

RI-TRP-R9UR from Texas Instruments is an ISO 11784/11785-compliant 134.2 kHz HDX (Half Duplex) RFID transponder disk with 64-bit read-only memory, operating from –25°C to +85°C, and housed in an 85.5 mm × 5.5 mm acrylate-styrene-acrylonitrile (ASA) black housing. It delivers stable read performance in access control, vehicle identification, and container tracking systems without onboard power.

For engineers reviewing the RI-TRP-R9UR datasheet, RI-TRP-R9UR pinout, RI-TRP-R9UR application, or RI-TRP-R9UR equivalent, key selection considerations include its HDX modulation scheme, batteryless operation, IP53-rated enclosure, 70 ms typical read time, and immunity to non-metallic material interference.

Technical Context

The RI-TRP-R9UR implements Half-Duplex (HDX) communication at 134.2 kHz using FSK modulation (134.2 kHz / 123.2 kHz), drawing power entirely from the reader's magnetic field. Its patented tuning process ensures consistent coupling and signal integrity across varying antenna geometries and environmental conditions.

It supports only read operations - no write capability - and stores a fixed 64-bit identifier in a single memory page. EMC resilience is confirmed per IEC standards, with verified signal penetration through non-metallic barriers and mechanical robustness validated under IEC 68-2-27 shock and IEC 68-2-6 vibration profiles.

Key Specifications

Pinout & Package

RI-TRP-R9UR is a passive RFID transponder disk with no electrical pins or terminals. It contains an integrated coil and tuned LC circuit encapsulated within an ASA polymer housing. No external connections are required - operation relies solely on inductive coupling with a compatible 134.2 kHz reader antenna.

FAQ

What is the operating frequency and communication protocol of the RI-TRP-R9UR?

The RI-TRP-R9UR operates at 134.2 kHz using Half-Duplex (HDX) communication with FSK modulation (134.2 kHz / 123.2 kHz). It is fully compliant with ISO/IEC 11784 and 11785 standards, ensuring interoperability with certified LF RFID readers used in animal identification, vehicle access, and logistics systems. Its HDX architecture enables robust data exchange without requiring an internal power source.

Does the RI-TRP-R9UR support read/write functionality?

No, the RI-TRP-R9UR is a read-only transponder with 64 bits of factory-programmed memory. Unlike the RI-TRP-W9UR variant, it does not support field programming. This design enhances long-term reliability and eliminates wear-out concerns associated with EEPROM cycling, making the RI-TRP-R9UR ideal for permanent ID applications such as livestock tagging or fixed-asset labeling.

What environmental ratings apply to the RI-TRP-R9UR?

The RI-TRP-R9UR carries an IP53 ingress protection rating and is qualified for operation from –25°C to +85°C. Its acrylate-styrene-acrylonitrile (ASA) black housing provides resistance to UV exposure, impact, and moisture. Mechanical validation includes IEC 68-2-27 shock testing (15 g, half-sine) and IEC 68-2-6 vibration testing (10 g, 20–500 Hz), confirming suitability for outdoor and mobile deployment scenarios.

Can the RI-TRP-R9UR be embedded inside non-metallic materials?

Yes - the RI-TRP-R9UR is specifically designed to maintain reliable read performance when embedded in or mounted behind virtually all non-metallic materials, including plastic, wood, concrete, rubber, and fabric. This property stems from its optimized HDX tuning and 134.2 kHz magnetic coupling, which penetrates dielectric barriers without significant signal attenuation, enabling concealed or protected installation.

Is the RI-TRP-R9UR RoHS compliant and what is its packaging format?

The RI-TRP-R9UR is supplied in a custom RFIDP (RFID Package) format with TEE package drawing and zero pins - reflecting its passive, coil-integrated construction. While RoHS status is not explicitly published for RI-TRP-R9UR in available documentation, TI's standard policy applies: all active-orderable devices launched after 2006 are RoHS compliant unless otherwise noted. For full compliance verification, consult TI's official product content portal or contact Aetrix Electronics for certified material declarations.
