Texas Instruments RI-I16-114A-S1

Overview

RI-I16-114A-S1 from Texas Instruments is a passive 13.56 MHz HF RFID transponder inlay in 24.2 mm circular format, compliant with ISO/IEC 15693-2,-3 and ISO/IEC 18000-3 standards, featuring 256-bit user EEPROM memory, factory-programmed 64-bit UID, and resonance frequency of 13.70 MHz ±400 kHz optimized for integration into paper or PVC laminates used in smart labels.

For engineers reviewing the RI-I16-114A-S1 datasheet, RI-I16-114A-S1 antenna size, RI-I16-114A-S1 activation field strength, or RI-I16-114A-S1 equivalent, this inlay supports high-speed inventory of up to 50 tags/sec, password-protected write operations, individual block locking, and AFI support - critical for asset tagging, anti-counterfeit labeling, and electronic ticketing applications requiring reliable read/write performance after lamination.

Technical Context

The RI-I16-114A-S1 implements full-duplex communication using ASK or FSK subcarrier modulation on the uplink and ASK (10–30% or 100%) with pulse-position coding on the downlink. It supports all ISO/IEC 15693 mandatory commands including Inventory, Read_Single_Block, Write_Single_Block, and Lock_Block, plus TI-custom Kill and WriteSingleBlockPwd commands.

Its resonant circuit integrates a flip-chip mounted microchip with an aluminum antenna and laser-trimmed capacitor formed by dual-layer aluminum on PET foil, enabling per-device frequency tuning to compensate detuning from substrate integration - confirmed by its specified 13.70 MHz ±400 kHz resonance at 25°C after paper/PVC lamination.

Key Specifications

Pinout & Package

This is a passive RFID transponder inlay with no electrical pins or terminals. It consists of a silicon chip flip-chip bonded to an aluminum antenna pattern embedded in a PET substrate, forming a monolithic resonant structure. No external connections are made - coupling occurs wirelessly via magnetic induction at 13.56 MHz.

FAQ

What is the resonance frequency specification for RI-I16-114A-S1, and why is it offset?

The RI-I16-114A-S1 has a passive resonance frequency of 13.70 MHz ±400 kHz at 25°C, intentionally offset to compensate for detuning that occurs when the inlay is laminated into paper or PVC substrates. This pre-compensation ensures the final assembled label maintains optimal 13.56 MHz operation, maximizing read/write reliability in end-use conditions - a key differentiator confirmed in Table 2-5 of the SCBU009B reference guide.

Does RI-I16-114A-S1 support password-protected writes, and how is it implemented?

Yes, RI-I16-114A-S1 supports password-protected writes via the TI-custom WriteSingleBlockPwd command. This command requires a valid password to modify memory blocks previously locked with the Lock_Block command. The password mechanism is implemented in firmware and validated per ISO/IEC 15693 protocol - enabling secure reprogramming of protected data fields without exposing the entire memory array.

What is the maximum number of tags RI-I16-114A-S1 can support in simultaneous inventory mode?

The RI-I16-114A-S1 supports simultaneous identification of up to 50 tags per second, as stated in Table 2-1 of the SCBU009B specification. This performance depends on reader/antenna capabilities and environmental conditions but is enabled by the inlay's ISO/IEC 15693-compliant anticollision protocol and fast frame synchronization - allowing high-throughput scanning in logistics or retail inventory scenarios.

Can RI-I16-114A-S1 be integrated into PVC-based smart cards, and what design consideration applies?

Yes, RI-I16-114A-S1 is explicitly qualified for integration into both paper and PVC laminates, as noted in Table 2-5 footnote (1). Its 13.70 MHz ±400 kHz resonance offset is engineered to counteract the dielectric loading effect of PVC, ensuring stable 13.56 MHz operation post-lamination - eliminating the need for custom tuning during card manufacturing.

What memory organization does RI-I16-114A-S1 use, and how is data protection enforced?

RI-I16-114A-S1 uses 256-bit user memory organized in eight 32-bit blocks, each individually lockable via the Lock_Block command. Once locked, a block can only be rewritten using the password-protected WriteSingleBlockPwd command. This architecture - detailed in Figure 1-3 and Section 1.5 - enables flexible security partitioning, such as locking UID-related metadata while leaving payload fields open for field updates.
