Texas Instruments RI-TH1-CB1A-00

Overview

RI-TH1-CB1A-00 from Texas Instruments is an ISO/IEC 15693-compliant 13.56 MHz vicinity card transponder with 2 kbit user memory (64 × 32-bit blocks), factory-programmed 64-bit UID, and support for read/write, block locking, and simultaneous identification of up to 50 tags/sec. It serves as a contactless smart label in access control, public transit ticketing, and warehouse management systems.

For engineers reviewing the RI-TH1-CB1A-00 datasheet, RI-TH1-CB1A-00 pinout, RI-TH1-CB1A-00 application, or RI-TH1-CB1A-00 equivalent, key selection considerations include its PVC-based ISO 7810 form factor (85.6 × 54 × 0.76 mm), thermal-transfer printability, -25°C to +50°C operating range, and TI-custom command extensions beyond ISO 15693 baseline.

Technical Context

The RI-TH1-CB1A-00 implements a passive RFID transponder architecture compliant with ISO/IEC 15693, operating at 13.56 MHz via magnetic coupling. It uses an integrated antenna coil and on-chip demodulator/decoder to respond to reader commands without onboard power.

It supports mandatory and optional ISO 15693 commands-including Inventory, Read_Single_Block (0x20), Write_Single_Block (0x21), Lock_Block (0x22), and Get_System_Info (0x2B)-plus TI-specific extensions like Write_2_Blocks (0xA2) and Lock_2_Blocks (0xA3), enabling enhanced system-level flexibility in multi-tag environments.

Key Specifications

Pinout & Package

This is a passive RFID card with no electrical pins or terminals. It features an embedded planar antenna coil and monolithic IC die encapsulated within a 0.76 mm thick ISO 7810-compliant PVC substrate (85.6 mm × 54 mm). No external connections are required-operation is fully contactless via magnetic field coupling.

FAQ

What is the operating frequency and standard compliance of the RI-TH1-CB1A-00?

The RI-TH1-CB1A-00 operates at 13.56 MHz and is fully compliant with ISO/IEC 15693:2000. This ensures interoperability with certified readers worldwide and defines its role as a vicinity-range passive transponder. Its RF interface requires no internal power source and relies entirely on magnetic field coupling from the reader antenna. The RI-TH1-CB1A-00 also supports extended TI-specific commands beyond the ISO baseline.

How much user memory does the RI-TH1-CB1A-00 provide, and how is it organized?

The RI-TH1-CB1A-00 provides 2 kbit (2048 bits) of user-programmable memory, organized into 64 blocks of 32 bits each. This structure supports efficient block-level read, write, and lock operations. Memory includes dedicated areas for DSFID, AFI, IC version, and UID - all factory-programmed. The RI-TH1-CB1A-00 allows selective locking of individual blocks to protect sensitive data while permitting updates to other sections.

What are the environmental ratings and physical dimensions of the RI-TH1-CB1A-00?

The RI-TH1-CB1A-00 meets ISO 7810 specifications: 85.6 mm × 54 mm × 0.76 mm, with a 5 g mass and glossy white PVC construction. It operates from -25°C to +50°C and stores within the same range. Mechanical stability complies with ISO 10373 for bending and torsion. The RI-TH1-CB1A-00 is not designed for punching or clipping - pouch mounting is recommended to preserve antenna integrity.

Does the RI-TH1-CB1A-00 support simultaneous tag identification, and what is its performance limit?

Yes, the RI-TH1-CB1A-00 supports simultaneous identification of up to 50 tags per second, subject to reader and antenna configuration. This capability relies on anti-collision protocols defined in ISO/IEC 15693 and is enhanced by TI's optimized command timing and response latency. The RI-TH1-CB1A-00 achieves this throughput without requiring host-side arbitration - all collision resolution occurs at the transponder level during inventory rounds.

What printing methods are supported for customizing the RI-TH1-CB1A-00 surface?

The RI-TH1-CB1A-00 supports thermotransfer, tampon, and silkscreen printing on its glossy PVC surface. Thermotransfer is the most common method, enabling high-resolution, durable text and barcode printing directly onto the card face. No special surface treatment or priming is required. The RI-TH1-CB1A-00's 0.76 mm thickness and flat geometry ensure compatibility with standard ID card printers and laminators.
