Product details
Overview
RI-TRP-R9BK-20 from Texas Instruments is a batteryless, read-only LF RFID transponder operating at 134.2 kHz using HDX (Half Duplex) transmission and FSK modulation (134.2 kHz / 123.2 kHz). It provides 64-bit user memory in a single page, achieves ≤20 cm typical reading range, and is encapsulated in IP68-rated black plastic for harsh industrial environments.
For engineers reviewing the RI-TRP-R9BK-20 datasheet, RI-TRP-R9BK-20 pinout, RI-TRP-R9BK-20 application, or RI-TRP-R9BK-20 equivalent, key selection factors include its HDX protocol compliance, 64-bit read-only memory architecture, 134.2 kHz carrier frequency, IP68 environmental rating, and batteryless operation powered solely by reader field coupling.
Technical Context
This transponder implements Half-Duplex (HDX) communication: the reader transmits energy and command during the first time slot, then pauses to allow the transponder to backscatter its 64-bit response in the second slot. No internal power source is used - energy harvesting occurs via inductive coupling at 134.2 kHz.
FSK modulation enables robust data recovery under electromagnetic noise; the 134.2 kHz / 123.2 kHz shift encodes logic states without requiring precise amplitude control. Memory is factory-programmed and read-only, with no write capability or programming cycles specified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz carrier - defines required reader antenna tuning and coil inductance design |
| Memory Size | 64 bits, single-page read-only - supports fixed ID encoding only, no field updates |
| Transmission Principle | HDX (Half Duplex) - mandates precise reader timing control with transmit/receive time-slot separation |
| Modulation | FSK (134.2 kHz / 123.2 kHz) - enables reliable demodulation in noisy industrial settings |
| Reading Range | ≤20 cm - determined by reader field strength, antenna geometry, and non-metallic mounting conditions |
| Environmental Rating | IP68 - permits continuous submersion and exposure to dust, oil, and cleaning agents |
| Operating Temperature | −40°C to +85°C (read only) - validated for automotive under-hood and industrial machinery use |
Pinout & Package
RI-TRP-R9BK-20 is a monolithic passive transponder with no electrical terminals or pins. It contains an integrated ferrite-core coil antenna and EEPROM die embedded in molded black plastic housing. The device interfaces exclusively via magnetic coupling to an external reader antenna.
Key Features
| Feature | Design Value |
|---|---|
| Batteryless operation | Eliminates maintenance and replacement logistics - powered entirely by reader's RF field |
| IP68 encapsulation | Enables direct mounting on hydraulic cylinders, motors, or food-processing equipment exposed to washdown |
| HDX protocol compliance | Ensures interoperability with TI-RFID LF readers and ISO/IEC 11784/11785–compliant infrastructure |
| 134.2 kHz FSK modulation | Provides immunity to amplitude noise and stable decoding in electrically noisy factory floors |
| Signal penetration | Reads reliably through plastic, rubber, wood, and concrete - no metal-mounting restrictions beyond standard LF limitations |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-W9WK | Read/write functionality, 80-bit memory (64 user + 16-bit CRC), −40°C to +70°C programming temp | Supports field-updatable IDs and calibration data; requires compatible TI-RFID writer hardware | Select when dynamic data writing is required; RI-TRP-R9BK-20 remains optimal for static ID-only use cases |
| EM4102 (EM Microelectronic) | 125 kHz carrier, Manchester-encoded, 128-bit read-only, no IP68 rating, −25°C to +70°C | Limited to indoor, non-washdown environments; incompatible with 134.2 kHz HDX readers | Only suitable where 125 kHz infrastructure exists and environmental ruggedness is not required |
Compared with RI-TRP-W9WK and EM4102, RI-TRP-R9BK-20 delivers superior environmental resilience (IP68, −40°C to +85°C read), strict 134.2 kHz HDX compliance for livestock and industrial standards, and zero-power reliability - making it the preferred choice for permanent outdoor, automotive, or food-grade deployments where ID immutability and ruggedness are mandatory.

FAQ
What is the operating frequency and modulation scheme of the RI-TRP-R9BK-20?
The RI-TRP-R9BK-20 operates at a fixed carrier frequency of 134.2 kHz and uses Frequency Shift Keying (FSK) modulation with shifts between 134.2 kHz and 123.2 kHz. This modulation enables robust data recovery in electrically noisy industrial settings and is fully compliant with ISO/IEC 11784/11785 standards for LF RFID systems.
Does the RI-TRP-R9BK-20 support read/write functionality?
No, the RI-TRP-R9BK-20 is strictly read-only. It contains 64 bits of factory-programmed memory in a single page and lacks any write circuitry or programming interface. For read/write capability, consider the RI-TRP-W9WK variant, which offers 80-bit memory with 64 programmable bits and CRC support.
What environmental certifications does the RI-TRP-R9BK-20 hold?
The RI-TRP-R9BK-20 is rated IP68 for dust and water immersion, validated per IEC 60529. It operates from −40°C to +85°C during read operations and withstands storage at +125°C for up to 1000 hours or +175°C for 5 minutes - making it suitable for automotive under-hood, food processing, and outdoor industrial applications.
How is power supplied to the RI-TRP-R9BK-20 during operation?
The RI-TRP-R9BK-20 is completely batteryless and derives all operating power from the magnetic field generated by the reader antenna via inductive coupling. Its internal coil harvests energy during the reader's transmit phase, enabling the HDX backscatter response without any onboard power source or maintenance requirement.
Is the RI-TRP-R9BK-20 compatible with standard ISO 11784/11785 readers?
Yes, the RI-TRP-R9BK-20 implements the HDX protocol and 134.2 kHz FSK modulation defined in ISO/IEC 11784 and 11785. It is interoperable with certified readers from Texas Instruments and other vendors supporting that standard - including livestock identification systems and industrial access control infrastructure.
