Product details
Overview
RI-TRP-DR2B from Texas Instruments is a 32 mm hermetically sealed glass LF RFID transponder operating at 134.2 kHz, compliant with ISO/IEC 11784/11785, supporting MPT (Multi-Purpose Transponder) functionality with 1360-bit memory (17 R/W pages), and rated for –25°C to +85°C operation during both read and program cycles in access control and asset tracking systems.
For engineers reviewing the RI-TRP-DR2B datasheet, RI-TRP-DR2B pinout, RI-TRP-DR2B application, or RI-TRP-DR2B equivalent, this page delivers verified technical context, exact memory architecture, HDX half-duplex transmission behavior, real-world read/program timing (86 ms / 293 ms), and validated alternatives for ISO-compliant LF RFID system integration.
Technical Context
The RI-TRP-DR2B implements Half-Duplex (HDX) communication using FSK modulation (134.2 kHz / 123.2 kHz), deriving power entirely from the reader's magnetic field-no battery required. It uses TI's patented tuning process to stabilize resonance and ensure consistent coupling across non-metallic media.
As an MPT-type transponder, it provides 1360 bits of user-programmable memory organized into 17 R/W pages, with each page supporting 64 data bits plus 16-bit CRC CCITT block check character per TI-RFID™LF reader conventions. Its glass encapsulation (Φ3.85 ± 0.05 mm × 32.2 ± 0.6 mm) ensures hermetic sealing and immunity to normal electromagnetic interference and x-rays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 134.2 kHz - fixed resonant frequency enabling interoperability with ISO 11784/11785 readers |
| Memory Capacity | 1360 bits across 17 R/W pages - supports complex identification, configuration, and logging data in single transponder |
| Read Time | 86 ms - defines minimum dwell time required for reliable data capture in high-throughput scanning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MPT-type LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-IR2B | Same 1360-bit MPT memory and 17 R/W pages, but includes 24-bit Selective Address width for multi-transponder arbitration | Required where multiple transponders operate within same reader field (e.g., stacked containers) | Select RI-TRP-IR2B when selective addressing or collision avoidance is needed; otherwise RI-TRP-DR2B suffices |
| EM4102 | 64-bit read-only, no write capability, no MPT structure, lower memory density, no CRC support per page | Suitable only for static ID applications without field updates or data integrity requirements | Choose EM4102 only for cost-sensitive, immutable ID use cases; RI-TRP-DR2B is mandatory for R/W and CRC-protected data |
Compared with RI-TRP-IR2B, RI-TRP-DR2B omits selective addressing but maintains identical memory size and reliability-ideal for single-tag-per-read scenarios. Versus EM4102, RI-TRP-DR2B adds full programmability, error detection, and ISO-compliant MPT architecture, enabling dynamic asset management rather than static identification.

FAQ
What is the memory architecture of the RI-TRP-DR2B?
The RI-TRP-DR2B implements a 1360-bit MPT (Multi-Purpose Transponder) memory organized into 17 read/write pages. Each page is structured with 64 user-programmable bits and a 16-bit CRC CCITT block check character, as recommended by TI-RFID™LF readers for data integrity. This architecture enables robust, field-updatable identification and logging without external power.
Does the RI-TRP-DR2B require a battery?
No, the RI-TRP-DR2B is a fully passive transponder powered exclusively by the magnetic field generated by an ISO-compliant 134.2 kHz reader. It contains no battery or energy storage element, enabling maintenance-free operation for the lifetime of the glass encapsulation-typically exceeding 10 years in stable environments.
What is the maximum operating temperature for programming the RI-TRP-DR2B?
The RI-TRP-DR2B supports programming across –25°C to +85°C, matching its read temperature range. This full-range programmability allows in-field reconfiguration in outdoor vehicle ID, waste management bins, and industrial container tracking-even under direct sunlight or cold ambient conditions-without thermal derating.
How does the RI-TRP-DR2B differ from the RI-TRP-RR2B?
The RI-TRP-RR2B is a 64-bit read-only transponder, while the RI-TRP-DR2B provides 1360-bit MPT memory with full read/write capability across 17 pages. The RI-TRP-DR2B supports dynamic data updates and CRC-protected storage; the RI-TRP-RR2B is limited to static ID transmission and cannot be reprogrammed after manufacture.
Is the RI-TRP-DR2B compatible with standard ISO 11784/11785 readers?
Yes, the RI-TRP-DR2B is fully compliant with ISO/IEC 11784/11785 standards for low-frequency RFID transponders. It uses HDX (Half-Duplex) protocol with FSK modulation at 134.2 kHz and has been validated for interoperability with commercial readers from Identec, Texas Instruments, and other ISO-certified manufacturers.
