Texas Instruments RI-I03-110A-01

Overview

RI-I03-110A-01 from Texas Instruments is a passive HF RFID transponder inlay operating at 13.56 MHz, featuring 256-bit user-programmable memory organized in eight 32-bit blocks, factory-programmed 32-bit read-only number, and aluminum antenna on PET substrate. It is designed for contactless identification in smart labels and access control cards.

For engineers reviewing the RI-I03-110A-01 datasheet, RI-I03-110A-01 pinout, RI-I03-110A-01 application, or RI-I03-110A-01 equivalent, key selection considerations include activation field strength (112 dBμA/m read, 116 dBμA/m write), resonance frequency offset compensation (14.26 MHz ±400 kHz), memory endurance (100,000 programming cycles), and mechanical constraints (18 mm minimum bending radius).

Technical Context

This inlay implements ISO/IEC 15693-compliant air interface with Manchester-encoded uplink (26.7 kBd) and pulse-width-coded downlink (6.2/9 kBd), using AM 100% modulation for RX and dual-sideband TX frequencies (fc ±423.75 kHz / fc ±484.29 kHz). It supports simultaneous identification of up to 50 tags per second under reader-dependent conditions.

The device achieves frequency tuning via passive resonance offset (14.26 MHz) to compensate for dielectric loading when embedded in PVC, dropping to nominal 13.56 MHz operation under RF field activation. Data retention exceeds 10 years at +55°C, and memory is organized as eight individually addressable 32-bit blocks.

FAQ

What is the primary communication standard supported by RI-I03-110A-01?

The RI-I03-110A-01 implements the ISO/IEC 15693 standard for HF RFID air interface, supporting both single- and multiple-block read/write operations, inventory commands, and fast data rates (26.7 kBd uplink). It does not support ISO/IEC 14443 or NFC Forum Type standards. This makes RI-I03-110A-01 suitable for industrial and enterprise identification systems rather than consumer NFC handsets.

Can RI-I03-110A-01 be embedded directly into PVC cards without performance loss?

Yes - RI-I03-110A-01 is specifically tuned with a 14.26 MHz ±400 kHz resonance frequency to compensate for dielectric loading caused by PVC lamination. When exposed to the reader's activation field, its effective operating frequency drops precisely to 13.56 MHz. This intentional offset ensures full compliance and reliable read/write performance post-embedding, a key differentiator of RI-I03-110A-01 versus generic HF inlays.

What is the maximum number of tags the RI-I03-110A-01 can support in dense-reader environments?

The RI-I03-110A-01 supports simultaneous identification of up to 50 tags per second, as specified in its datasheet. This capability depends on reader firmware, antenna design, and field strength - not on RI-I03-110A-01 itself. The inlay implements ISO/IEC 15693's slotted ALOHA anti-collision protocol, enabling deterministic resolution in multi-tag fields. Performance remains consistent across its −25°C to +70°C operating range.

How is memory organized and accessed in RI-I03-110A-01?

RI-I03-110A-01 provides 256 bits of user-programmable memory structured as eight independent 32-bit blocks, each individually addressable and writable. The first block contains the factory-programmed 32-bit read-only number. Memory access follows ISO/IEC 15693 command sets, allowing block-level lock/unlock, read, and write operations - ensuring data integrity and selective update capability within RI-I03-110A-01 deployments.

What mechanical limitations must be observed when applying RI-I03-110A-01?

RI-I03-110A-01 has a minimum bending radius of 18 mm and must not be stretched, twisted, or creased beyond this limit. Its aluminum antenna and PET substrate tolerate repeated flexing within that constraint but are not rated for dynamic fatigue. Avoid direct exposure to solvents like acetone or MEK during lamination, and ensure adhesive compatibility - as chemical attack or excessive heat (>85°C) during curing may delaminate the antenna or degrade RI-I03-110A-01 performance.
