Texas Instruments RI-TH1-CB3A-00

Overview

RI-TH1-CB3A-00 from Texas Instruments is an ISO/IEC 15693-compliant 13.56 MHz vicinity transponder badge with 2 kbit user memory (64 × 32-bit blocks), factory-programmed 64-bit read-only ID, and integrated high-coercivity 3-track magnetic stripe. It serves as a secure, field-programmable physical credential for access control systems requiring biometric integration, time-stamped updates, and tamper-resistant identity storage.

For engineers reviewing the RI-TH1-CB3A-00 datasheet, RI-TH1-CB3A-00 application, RI-TH1-CB3A-00 memory organization, or RI-TH1-CB3A-00 equivalent, this badge delivers verified simultaneous identification of up to 50 tags/sec, >10-year data retention, and in-field programmability while maintaining ISO 7810 card dimensions (85.6 × 54 × 0.76 mm) and PVC-based durability across –25°C to +50°C.

Technical Context

The RI-TH1-CB3A-00 implements ISO/IEC 15693 air interface protocol at 13.56 MHz with 10%–100% ASK modulation support and 20%+ recommended reader modulation depth for optimal read coverage. Its Tag-it™ Smart Label silicon core enables read/write operations with block-level data locking and supports command sets including Inventory, Read Single Block, Write Single Block, and Lock Block.

It features factory-programmed immutable 64-bit UID for global uniqueness and cryptographic resistance to cloning, while retaining full field reprogrammability of user memory for dynamic credential updates such as timestamps, access codes, or emergency medical data - all stored independently of host infrastructure.

FAQ

What is the primary compliance standard for RI-TH1-CB3A-00?

The RI-TH1-CB3A-00 is fully compliant with ISO/IEC 15693 for vicinity cards operating at 13.56 MHz. This ensures interoperability with certified readers from multiple vendors and defines its communication protocol, modulation scheme, and anti-collision behavior. The RI-TH1-CB3A-00 also conforms to ISO 7810 for physical dimensions and ISO 7811 for its integrated magnetic stripe.

Does RI-TH1-CB3A-00 support both read and write operations?

Yes, the RI-TH1-CB3A-00 supports full read/write functionality with optional block-level data locking. User memory (2 kbit across 64 blocks) can be programmed in-the-field for dynamic data like timestamps or access codes. Factory-programmed 64-bit UID remains permanently read-only, ensuring immutable identity anchoring for the RI-TH1-CB3A-00.

What is the memory structure of RI-TH1-CB3A-00?

The RI-TH1-CB3A-00 organizes its 2 kbit user memory into 64 blocks of 32 bits each (4 bytes per block). This structure aligns with ISO/IEC 15693 command sets and enables efficient block-level reads, writes, and locks. Memory is non-volatile and retains data >10 years at +25°C - a key design feature of the RI-TH1-CB3A-00 for long-life credentialing.

Can RI-TH1-CB3A-00 be used with existing magnetic stripe infrastructure?

Yes, the RI-TH1-CB3A-00 integrates a high-coercivity 3-track magnetic stripe compliant with ISO 7811, enabling seamless integration with legacy access systems that rely on magstripe readers. This dual-interface capability allows phased migration from magstripe to RFID without replacing endpoint hardware - a defining attribute of the RI-TH1-CB3A-00.

What environmental conditions is RI-TH1-CB3A-00 rated for?

The RI-TH1-CB3A-00 operates reliably from –25°C to +50°C and stores within the same range, per ISO 7810 specifications. Its white PVC construction provides chemical resistance and thermal stability suitable for indoor office, healthcare, and industrial facility environments. These ratings are validated for the RI-TH1-CB3A-00 and apply across its full functional lifetime.
