Product details
Overview
RI-TRP-WE2B-30 from Texas Instruments is a hermetically sealed, glass-encapsulated low-frequency RFID transponder operating at 134.2 kHz with HDX (Half Duplex) transmission, 80-bit read/write memory, and ISO 11784/11785 compliance. It draws power exclusively from the reader's RF field and delivers stable performance in access control, vehicle identification, and container tracking applications.
For engineers reviewing the RI-TRP-WE2B-30 datasheet, RI-TRP-WE2B-30 pinout, RI-TRP-WE2B-30 application, or RI-TRP-WE2B-30 equivalent, key selection considerations include its batteryless operation, 30% programming range relative to reading range, 10,000-programming-cycle endurance, FSK modulation scheme, and glass-package mechanical robustness under IEC 68-2-27/68-2-6 stress conditions.
Technical Context
This transponder implements Half-Duplex (HDX) communication using Frequency Shift Keying between 134.2 kHz (carrier) and 123.2 kHz (data), enabling reliable bidirectional data exchange without an internal power source. Its patented tuning process ensures consistent resonance and impedance matching across units.
It operates over –25°C to +70°C during both read and write cycles, with storage capability up to +85°C. The 80-bit memory includes 64 user-programmable bits plus a 16-bit CRC CCITT block check character, as implemented by TI-RFid™ LF readers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-RE2B-30 | 64-bit read-only memory; no programming capability; identical package and operating frequency | Suitable only for static ID deployment where field updates are unnecessary | Select RI-TRP-WE2B-30 when dynamic data update (e.g., status flags, timestamps) is required |
| EM4102 (from EM Microelectronic) | Read-only 128-bit ROM; 125 kHz operation; epoxy-coated ceramic package; no HDX or FSK support | Limited to basic animal tagging or simple access cards without environmental resilience | Choose RI-TRP-WE2B-30 for ISO 11784/11785 compliance, glass hermeticity, and HDX-based reliability |

FAQ
What is the memory structure of the RI-TRP-WE2B-30?
The RI-TRP-WE2B-30 contains 80 bits of read/write memory organized as one page. TI recommends allocating 64 bits for user data and 16 bits for a CRC CCITT block check character-exactly as implemented by TI-RFid™ LF readers. This structure ensures data integrity during wireless programming and prevents corruption from electromagnetic interference.
Is the RI-TRP-WE2B-30 compatible with ISO 11784/11785 readers?
Yes, the RI-TRP-WE2B-30 is fully compliant with ISO/IEC 11784 and ISO/IEC 11785 standards. It uses HDX protocol and FSK modulation at 134.2 kHz, ensuring interoperability with certified LF RFID readers used in animal identification, vehicle access, and industrial tracking systems worldwide.
What is the maximum programming distance for the RI-TRP-WE2B-30?
The typical programming range for the RI-TRP-WE2B-30 is 30% of its specified reading range, which is ≤100 cm under optimal conditions. Therefore, maximum reliable programming distance is approximately 30 cm-dependent on reader antenna design, regulatory limits, and local electromagnetic environment.
Can the RI-TRP-WE2B-30 be embedded in metal environments?
No-the RI-TRP-WE2B-30 is insensitive to nonmetallic materials but cannot operate when mounted directly on or enclosed by conductive metals. Metal detunes the LC resonance and blocks magnetic coupling. For metal-mount applications, ferrite-backed or specially shielded variants-not the RI-TRP-WE2B-30-are required.
What mechanical standards does the RI-TRP-WE2B-30 meet?
The RI-TRP-WE2B-30 meets IEC 68-2-27 (mechanical shock) and IEC 68-2-6 (vibration) test requirements. Its hermetically sealed glass construction (Ø3.85 × 31.2 mm, 0.8 g) ensures survivability in high-vibration logistics, automotive, and waste-handling applications without degradation of RF performance.
