Texas Instruments RI-I11-114B-S1

Overview

RI-I11-114B-S1 from Texas Instruments is a passive 13.56 MHz HF RFID transponder inlay optimized for PVC lamination, featuring a factory-programmed 64-bit UID, 256-bit user EEPROM memory organized in eight 32-bit blocks, 14.4 MHz ±200 kHz resonance frequency (including detuning compensation), and operation across –25°C to 70°C. It enables secure read/write identification in smart labels for access control and anti-counterfeit tagging.

For engineers reviewing the RI-I11-114B-S1 datasheet, RI-I11-114B-S1 antenna dimensions, RI-I11-114B-S1 resonance tuning, or RI-I11-114B-S1 PVC lamination compatibility, this inlay delivers verified ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 compliance, field-programmable lockable memory, and deterministic activation field strength of 98 dBµA/m (read) and 101 dBµA/m (write) after lamination.

Technical Context

The RI-I11-114B-S1 implements full-duplex ASK/FSK subcarrier modulation per ISO/IEC 15693-3, supports all mandatory and optional commands including Inventory, Read_Single_Block, Write_Single_Block, Lock_Block, and TI-custom Kill and WriteSingleBlockPwd, and uses laser-trimmed aluminum capacitor layers on PET foil to achieve precise 14.4 MHz resonance offset for stable performance post-PVC lamination.

It features collision-resistant anticollision via 64-bit UID addressing, password-protected reprogramming of locked blocks, and CRC-secured frame-synchronized uplink/downlink communication - enabling simultaneous identification of up to 50 tags per second in reader-dependent configurations while maintaining data retention >10 years at 55°C.

Key Specifications

Pinout & Package

RI-I11-114B-S1 is a passive RFID inlay with no electrical pins or terminals. It consists of a flip-chip mounted microchip integrated into a resonant circuit formed by an aluminum antenna and laser-trimmed dual-layer aluminum capacitor on a 48 mm wide PET tape substrate. The device is supplied on cardboard reels (76.2 mm hub, ~60 mm outer width) with 5,000 units per reel.

FAQ

What is the resonance frequency specification for RI-I11-114B-S1 and why is it different from RI-I11-114A-S1?

The RI-I11-114B-S1 has a passive resonance frequency of 14.4 MHz ±200 kHz at 25°C, explicitly tuned to compensate for detuning caused by PVC lamination. This differs from the RI-I11-114A-S1 (13.86 MHz ±200 kHz), which is offset for paper integration. The 540 kHz shift ensures optimal RF coupling and read/write range after final PVC encapsulation - a key differentiator validated in TI's SCBU009B reference guide Table 2-2.

Does RI-I11-114B-S1 support password-protected writes to locked memory blocks?

Yes, RI-I11-114B-S1 supports the TI-custom WriteSingleBlockPwd command (0xA5), allowing authorized reprogramming of previously locked 32-bit memory blocks using a stored password. This capability is documented in Table 1-1 of the SCBU009B reference guide and enables secure field updates of application data without compromising immutable UID or AFI fields.

What is the maximum number of RI-I11-114B-S1 inlays that can be identified simultaneously by a single reader?

A single reader can identify up to 50 RI-I11-114B-S1 inlays per second, as specified in Table 2-1 of the SCBU009B reference guide. This performance relies on the device's ISO/IEC 15693-compliant anticollision algorithm and 64-bit UID addressing, and is dependent on reader hardware capabilities and RF field uniformity - not on the inlay itself.

Is RI-I11-114B-S1 compatible with standard ISO/IEC 15693 readers?

Yes, RI-I11-114B-S1 fully complies with ISO/IEC 15693-2 and -3 standards, supporting all mandatory commands (Inventory, Read_Single_Block, Write_Single_Block, Lock_Block) and optional features including AFI and extended addressing. Its ASK/FSK modulation schemes and frame synchronization ensure plug-and-play interoperability with certified ISO/IEC 15693 readers without firmware modification.

What are the mechanical handling limits for RI-I11-114B-S1 during label conversion?

RI-I11-114B-S1 supports a minimum bending radius of 18 mm and maximum tape tension of 10 N, as defined in Table 2-1 of SCBU009B. These limits ensure integrity of the aluminum antenna and flip-chip bond during high-speed die-cutting, laminating, or slitting processes - critical for maintaining consistent resonance and read performance in finished smart labels.
