Product details
Overview
RI-TRP-B9WK-05 from Texas Instruments is a batteryless 134.2 kHz HDX RFID transponder with 88-bit memory, Digital Signature (DST) encryption, 40-bit user-programmable encryption key, and IP68-rated plastic housing. It operates from -40°C to +85°C and delivers 24-bit encrypted response plus 24-bit serial number with CRC in <120 ms read time for secure access control systems.
For engineers reviewing the RI-TRP-B9WK-05 datasheet, RI-TRP-B9WK-05 pinout, RI-TRP-B9WK-05 application, or RI-TRP-B9WK-05 equivalent, key selection factors include HDX half-duplex protocol compliance, FSK modulation at 134.2/123.2 kHz, 132.5 dBµA/m activation field strength, DST cryptographic authentication, and IP68 mechanical robustness for embedded identification in harsh environments.
Technical Context
This transponder implements Texas Instruments' Digital Signature Transponder (DST) protocol, using challenge-response authentication with a 40-bit secret key and CRC-protected 48-bit response (24-bit cipher + 24-bit SN). It requires no internal power source and draws energy exclusively from the reader's magnetic field via inductive coupling.
Memory is organized across four lockable pages: 8-bit password, 8-bit ID, 32-bit factory-programmed serial number, and 40-bit encryption key. All user-programmable pages support permanent locking to prevent reprogramming after initial configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - Enables compatibility with ISO/IEC 11784/11785 low-frequency RFID readers. |
| Modulation | FSK (134.2 kHz / 123.2 kHz) - Provides noise-immune bidirectional communication in electrically noisy industrial settings. |
| Transmission Principle | HDX (Half Duplex) - Ensures reliable data exchange by separating reader transmit and transponder reply time slots. |
| Memory Capacity | 88 bits across 4 pages - Supports secure credential storage including lockable password, ID, serial number, and encryption key. |
| Reading Range | ≤ 20 cm - Sufficient for proximity-based access control, animal tagging, and tool identification without RF regulatory overreach. |
| Activation Field Strength | 132.5 dBµA/m @ 25°C - Defines minimum reader field intensity required to reliably power and interrogate the device. |
| Operating Temperature | -40°C to +85°C - Validates operation in automotive under-hood, industrial machinery, and outdoor asset tracking environments. |
| Protection Class | IP68 - Guarantees dust-tight and continuous submersion resistance, enabling use in washdown, marine, or buried applications. |
Pinout & Package
RI-TRP-B9WK-05 is a monolithic passive RFID transponder with no electrical pins or terminals. It uses an integrated coil antenna embedded within a 12.0 mm × 6.0 mm × 3.0 mm plastic wedge-shaped package (MIL-STD-883 compliant mechanical form factor).
Key Features
| Feature | Design Value |
|---|---|
| Digital Signature (DST) | 40-bit challenge-response crypto engine prevents cloning and replay attacks in high-security access systems. |
| Lockable Memory Pages | User can permanently lock password, ID, and encryption key pages after programming-ensuring immutable credential integrity. |
| Batteryless Operation | Derives all operating power from reader's magnetic field-eliminates maintenance, battery replacement, and environmental disposal concerns. |
| Signal Penetration | Reads through non-metallic materials (plastic, wood, concrete, water, human tissue)-enabling embedding in tools, implants, or sealed enclosures. |
| EMC Immunity | Factory-programmed data survives exposure to normal EMI and medical-grade x-rays-critical for healthcare and aerospace traceability. |
Applications
| Access Control Tags | Industrial Asset Tracking |
|---|---|
Use Scenario: Embedded in employee ID badges or vehicle key fobs for secure door entry and fleet authorization. IC Role / Device Role / Timing Role: Passive cryptographic transponder performing DST authentication upon magnetic field activation. Use Value: Prevents unauthorized duplication via 40-bit encrypted challenge-response and permanent memory locking. | Use Scenario: Mounted on CNC tools, molds, or robotic end-effectors for automated tool management and usage logging. IC Role / Device Role / Timing Role: Batteryless identifier providing unique, tamper-proof serial number and CRC-verified response during tool change cycles. Use Value: Enables zero-maintenance identification in oil, coolant, and vibration-prone manufacturing environments (IP68 + IEC 68-2-27/6). |
| Animal Identification | Medical Implant Tagging |
Use Scenario: Subcutaneously implanted in livestock for lifetime traceability and disease outbreak containment. IC Role / Device Role / Timing Role: Biocompatible passive tag delivering factory-locked 32-bit serial number and encrypted response under handheld reader interrogation. Use Value: Survives sterilization, x-ray imaging, and long-term tissue encapsulation while retaining data integrity (175°C/5 min + EMC immunity). | Use Scenario: Encapsulated in orthopedic implants or surgical instruments for UDI compliance and revision tracking. IC Role / Device Role / Timing Role: Hermetically sealed transponder providing cryptographically authenticated identity during OR inventory scans. Use Value: Maintains readability through metal-shielded trays and saline-soaked conditions due to HDX protocol and signal penetration capability. |
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-WRQ-05 | Same DST crypto core and 134.2 kHz HDX operation, but uses rectangular ceramic package (11.5 × 5.5 × 2.5 mm) instead of wedge plastic. | Better thermal stability in high-temp sterilization cycles; less impact-resistant than plastic wedge in mechanical handling. | Choose RI-TRP-WRQ-05 when repeated autoclaving (>135°C) is required; retain RI-TRP-B9WK-05 for ruggedized physical deployment. |
| EM4102 | Read-only 125 kHz IDIC with no encryption, no programmable memory, and ASK modulation-lacks DST, CRC, or lockable pages. | Suitable only for basic object identification where security and data integrity are not required. | Select EM4102 only for cost-sensitive, non-secure logistics tagging; RI-TRP-B9WK-05 is mandatory for authenticated access or regulated asset tracking. |
Compared with RI-TRP-WRQ-05 and EM4102, the RI-TRP-B9WK-05 uniquely combines wedge-form-factor durability, IP68 sealing, and full DST cryptographic authentication-making it the only option qualified for secure, maintenance-free, and environmentally hardened identification in regulated industrial and biomedical applications.

FAQ
What communication protocol does the RI-TRP-B9WK-05 use?
The RI-TRP-B9WK-05 uses the HDX (Half Duplex) protocol at 134.2 kHz with FSK modulation (134.2 kHz / 123.2 kHz). It implements Texas Instruments' proprietary Digital Signature Transponder (DST) challenge-response authentication, requiring a 40-bit encrypted reply plus 24-bit serial number with CRC verification-ensuring secure, anti-cloning identification.
Is the RI-TRP-B9WK-05 compatible with ISO/IEC 11784 and 11785 standards?
Yes, the RI-TRP-B9WK-05 complies with ISO/IEC 11784 (air interface) and 11785 (technical description) for low-frequency RFID transponders. Its 134.2 kHz operating frequency, HDX transmission principle, and FSK modulation meet the mandatory physical layer requirements defined in those standards for animal identification and industrial tagging systems.
Can the memory of the RI-TRP-B9WK-05 be reprogrammed after initial configuration?
Only before locking: Pages 1 (password), 2 (ID), and 4 (encryption key) are user-programmable and lockable. Once locked, they become permanently read-only. Page 3 (32-bit serial number and manufacturing code) is factory-programmed and locked at production-no reprogramming is possible for any page after lock activation.
What is the maximum reading distance for the RI-TRP-B9WK-05?
The typical reading range of the RI-TRP-B9WK-05 is ≤ 20 cm, dependent on reader antenna design, local RF regulations, and environmental conditions such as nearby metal or moisture. This range is consistent with ISO/IEC 11785-compliant LF RFID systems and validated under standard test conditions per TI's datasheet Rev. 05.
Does the RI-TRP-B9WK-05 require a battery or external power source?
No, the RI-TRP-B9WK-05 is fully batteryless and derives all operating energy from the magnetic field generated by the reader antenna via inductive coupling. This enables maintenance-free, multi-decade operation in embedded, implantable, or inaccessible installations without power infrastructure.
