Texas Instruments RI-TRP-W9QL-30

Overview

RI-TRP-W9QL-30 from Texas Instruments is a 30 mm disk-shaped, batteryless LF RFID transponder operating at 134.2 kHz with HDX (Half Duplex) transmission, ISO 11784/11785 compliance, 80-bit read/write memory, and IP67-rated POM housing. It delivers stable read/write performance in vehicle identification, container tracking, and waste management systems where non-metallic material penetration and environmental ruggedness are required.

For engineers reviewing the RI-TRP-W9QL-30 datasheet, RI-TRP-W9QL-30 pinout, RI-TRP-W9QL-30 application, or RI-TRP-W9QL-30 equivalent, key selection considerations include its HDX modulation scheme, 30% programming range relative to reading range, 100,000-programming-cycle endurance, and operational limits of –25°C to +70°C in harsh industrial environments.

Technical Context

This transponder uses patented TI tuning technology to ensure consistent resonance and coupling efficiency across production units. Its HDX architecture enables simultaneous reader-to-transponder power transfer and transponder-to-reader data transmission via FSK (134.2 kHz / 123.2 kHz), eliminating need for onboard power.

It operates exclusively in the low-frequency band and relies on magnetic field coupling - not RF radiation - making it insensitive to most non-metallic materials and compliant with global animal and asset identification standards. No internal oscillator or clock circuitry is present; timing is fully synchronized to the reader's carrier field.

Key Specifications

Pinout & Package

RI-TRP-W9QL-30 is a passive, two-terminal resonant LC device with no electrical pins or solderable terminals. It consists of a tuned coil-capacitor assembly embedded in a molded Poly-Oxy-Methylen (POM) disk (29.4 mm × 8.4 mm, 8 g), sealed to IP67. No external connections are required - coupling occurs wirelessly via magnetic field induction.

FAQ

What is the memory structure of the RI-TRP-W9QL-30?

The RI-TRP-W9QL-30 contains 80 bits of EEPROM organized as one page. TI recommends allocating 64 bits for user data and 16 bits for a CCITT CRC block check character. This structure ensures data integrity during wireless programming and is enforced by TI-RFid™LF readers - the RI-TRP-W9QL-30 itself does not validate CRC but stores it as written.

Does the RI-TRP-W9QL-30 require a battery or external power source?

No, the RI-TRP-W9QL-30 is entirely batteryless and derives all operating energy from the reader's magnetic field via inductive coupling. Its HDX architecture enables both power harvesting and backscatter communication without any onboard voltage regulator, oscillator, or power storage - a defining feature of the RI-TRP-W9QL-30 design.

What is the maximum programming distance for the RI-TRP-W9QL-30?

The typical programming distance for the RI-TRP-W9QL-30 is 30% of its specified reading range - approximately ≤18 cm under standard test conditions. Actual distance varies with reader antenna size, coil geometry, field strength, and local regulatory limits on magnetic field emissions, as stated in the official RI-TRP-W9QL-30 datasheet.

Is the RI-TRP-W9QL-30 suitable for outdoor or submerged installations?

Yes - the RI-TRP-W9QL-30 features an IP67-rated POM housing and passes IEC 68-2 mechanical shock and vibration tests. It is certified for continuous operation from –25°C to +70°C and withstands immersion up to 1 m for 30 minutes, making it appropriate for outdoor, underground, or washdown environments where the RI-TRP-W9QL-30 remains fully functional.

How does HDX differ from FDX-B in the context of the RI-TRP-W9QL-30?

HDX (Half Duplex) used by the RI-TRP-W9QL-30 separates reader transmission and transponder reply in time, using FSK at 134.2 kHz / 123.2 kHz. Unlike FDX-B, HDX provides higher noise immunity, longer effective range, and deterministic timing - critical for reliable operation in electrically noisy industrial sites where the RI-TRP-W9QL-30 is commonly deployed.
