The **RI-TRP-RFOB** is a specific model of a **Radio Frequency Identification (RFID) Transponder** manufactured by Texas Instruments (TI). It belongs to the TIRIS™ (Texas Instruments Registration and Identification System) product line. Specifically, this part is a **Disk Transponder** operating at Low Frequency (LF). --- ## 🛠️ Technical Specifications Below are the key technical parameters for the RI-TRP-RFOB: | Parameter | Specification | | :--- | :--- | | **Operating Frequency** | 134.2 kHz | | **Type** | Read-Only (RO) | | **Memory Size** | 64 Bits | | **Technology** | FM (Frequency Modulation) / FSK (Frequency Shift Keying) | | **Form Factor** | 30mm Disk (Coin shape) | | **Material** | PPS (Polyphenylene Sulfide) - High durability plastic | | **Operating Temperature** | -25°C to +70°C | | **Resonance Frequency** | 134.2 kHz (± 1.5 kHz) | --- ## 🏗️ Core Electronic Components The RI-TRP-RFOB is a **passive** electronic device, meaning it contains no battery. Its internal structure consists of three main electronic sections: ### 1. The Antenna Coil A micro-thin copper wire wound in a circular pattern. It serves two purposes: * **Energy Harvesting:** It captures the magnetic field from the RFID reader to power the chip. * **Communication:** It transmits the ID code back to the reader via backscatter. ### 2. The Resonance Capacitor Connected in parallel with the antenna coil, this capacitor creates an **LC Resonant Circuit**. It is precisely tuned to **134.2 kHz**, ensuring maximum power transfer and signal clarity. ### 3. The Integrated Circuit (IC) The "brain" of the transponder. It contains: * **Rectifier/Voltage Regulator:** Converts the AC signal from the antenna into DC power. * **Logic Controller:** Manages the timing and transmission sequence. * **EEPROM/ROM:** Stores the unique 64-bit identification code (programmed during manufacturing). --- ## 📋 Key Features & Applications ### Features * **Contactless:** No physical connection required. * **Durable:** The PPS housing is resistant to water, chemicals, and mechanical stress. * **Read-Only Security:** Since the ID is factory-programmed, it cannot be altered, preventing "cloning" via software overwriting. ### Common Applications * **Asset Tracking:** Tracking industrial pallets or containers. * **Waste Management:** Embedded in trash bins for automated billing. * **Access Control:** Used in key fobs or badges for building entry. * **Automation:** Identifying parts on a high-speed assembly line. ---
