Texas Instruments RI-I03-114A-S1

Overview

RI-I03-114A-S1 from Texas Instruments is a passive 13.56 MHz HF RFID transponder inlay compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 standards, featuring a miniature rectangular antenna (22.5 mm × 38 mm), 64-bit factory-programmed UID, 256-bit user EEPROM memory organized in eight 32-bit lockable blocks, and frequency tuning for reliable operation after integration into paper or PVC laminates.

For engineers reviewing the RI-I03-114A-S1 datasheet, RI-I03-114A-S1 pinout, RI-I03-114A-S1 application, or RI-I03-114A-S1 equivalent, this inlay supports high-speed inventory of up to 50 tags/sec, password-protected write operations, AFI support, and collision resolution in multi-tag environments - critical for label conversion, asset tagging, and access control system design.

Technical Context

The RI-I03-114A-S1 implements full-duplex ASK/FSK subcarrier modulation per ISO/IEC 15693, supporting both 1-out-of-4 and 1-out-of-256 pulse-position downlink coding. Its resonance circuit integrates a flip-chip mounted microchip with laser-trimmed aluminum capacitor layers on PET foil to achieve precise 13.86 MHz ±200 kHz tuning.

It operates across –25°C to 70°C, requires ≤109 dBµA/m field strength for read at 25°C post-lamination, and delivers 100,000 programming cycles with >10-year data retention at 55°C - enabling robust deployment in industrial labeling and smart ticketing applications where mechanical flexibility and environmental resilience are essential.

FAQ

What is the primary function of the RI-I03-114A-S1 in an RFID system?

The RI-I03-114A-S1 functions as a passive HF RFID transponder inlay that wirelessly receives power and commands from a 13.56 MHz reader antenna, stores and retrieves 256 bits of user data, and transmits its unique 64-bit UID for identification. It contains no active circuitry or battery and relies entirely on magnetic coupling for operation - making it ideal for disposable smart labels and embedded identification applications where size and flexibility are critical.

Does the RI-I03-114A-S1 require external power or a battery to operate?

No, the RI-I03-114A-S1 is a fully passive device that derives all operating power from the electromagnetic field generated by a compatible 13.56 MHz RFID reader antenna. Its integrated aluminum antenna and laser-trimmed capacitor form a resonant circuit that harvests sufficient energy to power the flip-chip microchip, execute commands, and backscatter response data - eliminating the need for batteries, wiring, or external power sources in any application using RI-I03-114A-S1.

How does the frequency offset in the RI-I03-114A-S1 improve performance after lamination?

The RI-I03-114A-S1 is pre-tuned to 13.86 MHz ±200 kHz to compensate for detuning caused by dielectric loading when laminated into paper or PVC substrates. This intentional offset ensures the final resonant frequency remains centered at 13.56 MHz in the end-use environment - maintaining optimal coupling efficiency, read range, and reliability without requiring custom antenna redesign or post-lamination tuning for each label material.

Can the memory of the RI-I03-114A-S1 be rewritten multiple times, and what limits its endurance?

Yes, the 256-bit EEPROM memory of the RI-I03-114A-S1 supports up to 100,000 write/erase cycles at 25°C, with data retention exceeding 10 years at 55°C. Endurance is limited by charge trapping in the floating-gate structure of the nonvolatile memory cells. Each 32-bit block can be independently locked, and once locked, only password-protected write commands can modify its contents - ensuring long-term data integrity in applications like access credentials or calibration records stored on RI-I03-114A-S1.

Is the RI-I03-114A-S1 compatible with standard ISO/IEC 15693 readers?

Yes, the RI-I03-114A-S1 fully complies with ISO/IEC 15693-2 and -3, supporting mandatory commands (Inventory, Read_Single_Block, Write_Single_Block, Lock_Block) and optional features including AFI and password-protected writes. It operates in both addressed and non-addressed modes, handles ASK/FSK uplink modulation, and resolves collisions using the standard anticollision protocol - ensuring interoperability with all certified ISO/IEC 15693 readers without firmware or configuration changes for RI-I03-114A-S1 deployment.
