Texas Instruments RI-I02-114B-S1

Overview

RI-I02-114B-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 64-bit factory-programmed UID, 256-bit user EEPROM memory organized in eight 32-bit blocks, laser-trimmed aluminum capacitor tuning, and optimized resonance at 14.4 MHz ±200 kHz for PVC lamination integration. It serves as the core embedded element in disposable smart labels for asset tagging and access control.

For engineers reviewing the RI-I02-114B-S1 datasheet, RI-I02-114B-S1 pinout, RI-I02-114B-S1 application, or RI-I02-114B-S1 equivalent, this page delivers verified mechanical dimensions (45 mm × 76 mm rectangle), activation field strength requirements (94 dBµA/m typical read), frequency offset rationale, memory lock/write security model, and reel delivery specifications (5,000 units per 76.2 mm hub reel).

Technical Context

The RI-I02-114B-S1 implements full-duplex ASK/FSK uplink communication with 1-out-of-4 or 1-out-of-256 downlink coding, supports all ISO/IEC 15693 mandatory commands (Inventory, Read_Single_Block, Write_Single_Block, Lock_Block), and includes TI-custom Kill and password-protected WriteSingleBlockPwd commands. Its anticollision mechanism enables simultaneous identification of up to 50 tags per second.

Resonance tuning uses laser-trimmed dual-layer aluminum capacitor on PET foil to compensate detuning from PVC lamination; the 14.4 MHz ±200 kHz target frequency includes intentional offset to maintain 13.56 MHz operation post-lamination. Memory blocks are individually lockable, and locked data requires password authentication for reprogramming.

Key Specifications

Pinout & Package

RI-I02-114B-S1 is a passive RFID inlay with no electrical pins or terminals. It consists of a flip-chip mounted IC connected via through contacts to an integrated aluminum antenna on PET substrate. The device has no leads, pads, or solderable interfaces - it functions solely via inductive coupling within a reader's RF field.

FAQ

What is the primary functional difference between RI-I02-114B-S1 and RI-I02-114A-S1?

The RI-I02-114B-S1 is tuned to a passive resonance frequency of 14.4 MHz ±200 kHz to compensate for detuning caused by PVC lamination, whereas RI-I02-114A-S1 is tuned to 13.86 MHz ±200 kHz for paper-based substrates. This offset ensures the RI-I02-114B-S1 maintains nominal 13.56 MHz operation after PVC integration - a critical design requirement for durable badges and laminated tickets. Both share identical memory structure, command set, and mechanical form factor.

Does RI-I02-114B-S1 require external power or a battery?

No, RI-I02-114B-S1 is a fully passive transponder inlay that derives all operating power from the electromagnetic field generated by an ISO/IEC 15693-compliant HF reader antenna. It contains no battery, internal oscillator, or active circuitry - energy harvesting occurs via inductive coupling between the reader's coil and the inlay's integrated aluminum antenna.

How is memory protected against unauthorized writes on RI-I02-114B-S1?

RI-I02-114B-S1 supports per-block locking: each of its eight 32-bit memory blocks can be individually locked using the Lock_Block command. Once locked, a block cannot be rewritten unless the password-protected WriteSingleBlockPwd command is used - requiring knowledge of the 32-bit password stored in reserved memory. The factory-programmed 64-bit UID is permanently locked and non-modifiable.

What mechanical handling limits apply to RI-I02-114B-S1 during label conversion?

RI-I02-114B-S1 must not be bent below an 18 mm radius, and tape tension during unwinding must remain ≤10 N. It is supplied on 76.2 mm hub reels with 5,000 units per reel, 96 mm pitch, and chipless leader/trailer sections. Static pressure on the chip area must not exceed 10 N/mm² - exceeding these limits risks delamination or capacitor damage, degrading resonance stability and read reliability.

Can RI-I02-114B-S1 be used with ISO/IEC 14443 readers?

No, RI-I02-114B-S1 is strictly compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 for vicinity-coupling (up to ~1 m) HF systems, not ISO/IEC 14443-A/B for proximity-coupling (≤10 cm). Its modulation schemes (ASK/FSK uplink, 1-out-of-4 downlink), frame structure, and 64-bit UID format are incompatible with 14443 protocols. Use only with readers certified for ISO 15693 operation.
