Product details
Overview
RI-INL-W9QM-30 from Texas Instruments is a 24 mm LF circular RFID inlay operating at 134.2 kHz, compliant with ISO/IEC 11784/11785, supporting 80-bit read/write memory, HDX (Half Duplex) modulation, and batteryless operation via reader field coupling. It delivers stable performance in access control, vehicle identification, and asset management applications.
For engineers reviewing the RI-INL-W9QM-30 datasheet, RI-INL-W9QM-30 pinout, RI-INL-W9QM-30 application, or RI-INL-W9QM-30 equivalent, key selection criteria include resonance frequency stability, read/write memory capacity, immunity to non-metallic materials, programming field strength requirement, and operational temperature range.
Technical Context
This inlay implements TI's patented transponder tuning process to ensure consistent read/write performance across production units. Its HDX architecture enables half-duplex communication using FSK modulation between 134.2 kHz and 123.2 kHz, with power harvested entirely from the reader's RF field.
The device features a fixed 80-bit memory structure-configured as one page with 64 user-programmable bits plus 16-bit CRC CCITT-and maintains reliable signal penetration through virtually all non-metallic materials without requiring onboard power or external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resonance Frequency | 134.2 kHz - defines carrier frequency for ISO/IEC 11784/11785-compliant communication |
| Memory Capacity | 80-bit read/write - supports one programmable page with embedded 16-bit CRC for data integrity |
| Operating Temperature | –25°C to +70°C - validated for industrial environments including waste management and outdoor vehicle ID |
| Reading Range | ≤60 cm - dependent on reader antenna design and regulatory limits, not device-limited |
| Programming Field Strength | 129 dBμA/m @ 25°C - minimum RF field intensity required to reliably write data |
| Signal Penetration | Effective through all non-metallic materials - enables embedding in plastic, wood, concrete, and composite housings |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID inlay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-INL-R9QM-30 | 64-bit read-only memory; no write capability; identical resonance frequency and mechanical specs | Suitable only for static ID applications where data immutability is required | Select when write functionality is unnecessary and cost sensitivity favors simpler memory architecture |
| EM4102-24 | 64-bit read-only; operates at 125 kHz; lacks HDX modulation and TI's patented tuning process | Compatible with legacy 125 kHz readers but exhibits lower noise immunity and inconsistent read range | Choose only if integrating with existing 125 kHz infrastructure and ISO 11785 compliance is not required |
Compared with RI-INL-R9QM-30 and EM4102-24, the RI-INL-W9QM-30 uniquely supports field-updatable data via 80-bit HDX read/write while maintaining full ISO/IEC 11784/11785 conformance and TI-tuned resonance stability-critical for traceability systems requiring dynamic payload updates.

FAQ
What is the memory configuration of the RI-INL-W9QM-30?
The RI-INL-W9QM-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 CRC CCITT block check character to ensure data integrity during programming and read operations. This structure is fixed and cannot be reconfigured.
Does the RI-INL-W9QM-30 require a battery or external power source?
No, the RI-INL-W9QM-30 is a fully passive device powered solely by the electromagnetic field generated by an ISO/IEC 11785-compliant reader. It contains no battery, capacitor, or energy storage element-enabling maintenance-free operation over decades in properly encapsulated deployments.
Is the RI-INL-W9QM-30 compatible with standard LF RFID readers?
Yes, the RI-INL-W9QM-30 complies with ISO/IEC 11784/11785 standards and uses HDX modulation at 134.2 kHz, ensuring interoperability with certified LF readers used in animal identification, access control, and industrial tracking systems worldwide.
What environmental conditions can the RI-INL-W9QM-30 withstand?
The RI-INL-W9QM-30 is rated for operation from –25°C to +70°C and has passed IEC 68-2-27 (200 g shock) and IEC 68-2-6 (5 g vibration, 10–500 Hz) testing. Its overmolded construction provides resistance to moisture, dust, and mechanical stress in demanding logistics and outdoor deployment scenarios.
How does the patented tuning process improve RI-INL-W9QM-30 performance?
TI's patented transponder tuning process precisely matches the inlay's coil and IC impedance to achieve stable 134.2 kHz resonance across production batches. This minimizes read/write failures due to detuning caused by encapsulation materials or environmental shifts-directly improving first-pass yield in high-volume tagging operations.
