Product details
Overview
RF37S114HTFJB from Texas Instruments is an ISO/IEC 15693-2/3 and ISO/IEC 18000-3 compliant NFC Tag Type 5 transponder with integrated antenna, 256-bit user memory (eight 32-bit blocks), 64-bit factory-programmed UID, and AFI support. It operates at 13.56 MHz with typical read/write activation field strength of 136.0 dBµA/m and supports fast anticollision for up to 50 tags per second in supply chain and asset tracking applications.
For engineers reviewing the RF37S114HTFJB datasheet, RF37S114HTFJB pinout, RF37S114HTFJB application, or RF37S114HTFJB equivalent, this page delivers verified technical context, memory organization, physical dimensions, operating temperature range (–25°C to 70°C), data retention (>10 years at 55°C), and programming endurance (100,000 cycles) - all confirmed from TI's production-grade SCBS907 datasheet.
Technical Context
The RF37S114HTFJB implements a passive HF RFID transponder architecture compliant with ISO/IEC 15693 and ISO/IEC 18000-3 Mode 1. It requires no external antenna due to its monolithic 4 mm × 4 mm × 0.66 mm RFIDP package with embedded coil structure.
It supports mandatory ISO/IEC 15693 commands including Inventory, Read_Single_Block, Write_Single_Block, and Lock_Block, but excludes optional Request Mode and Stay Quiet. Memory is organized as eight 32-bit blocks with AFI byte at address 0x06 and lock bits at 0x08–0x0A.

Pinout & Package
RF37S114HTFJB uses the RFIDP (0) package - a monolithic 4 mm × 4 mm × 0.66 mm surface-mount transponder with integrated antenna coil. It has no external pins or terminals; coupling is achieved entirely via inductive RF field interaction. No solderable leads or electrical interface connections are present.
Key Features
| Feature | Design Value |
|---|---|
| Integrated Antenna | Enables drop-in deployment without antenna design, layout, or tuning effort - reduces BOM and validation time. |
| NFC Tag Type 5 Compliance | Guarantees interoperability with NFC-enabled smartphones and industrial readers supporting ISO/IEC 15693. |
| Fast Anticollision | Supports simultaneous identification of up to 50 tags per second - critical for high-throughput warehouse scanning. |
| Lockable Memory Blocks | Per-block write protection (via Lock_Block command) secures calibration data or firmware version fields from overwrite. |
| AFI Filtering | Allows readers to scan only tags matching a specific Application Family Identifier - improves system-level selectivity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NFC transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST25DV02K | 2-Kbit EEPROM memory, I²C + RF dual-interface, 13.56 MHz, no integrated antenna (requires external coil) | Requires antenna design and microcontroller integration; suited for active device pairing, not passive-only use cases | Select when bidirectional communication and local processing are needed - not for pure passive tag replacement |
| NT3H2111W0FHKH | 1-Kbit NFC Forum Type 4B tag, NDEF-compliant, integrated antenna, 13.56 MHz, 10-year data retention | Lacks ISO/IEC 18000-3 support and AFI filtering; optimized for smartphone-centric NFC, not industrial readers | Prefer for consumer-facing NFC experiences (e.g., smart posters); avoid where ISO/IEC 15693 anticollision or AFI-based filtering is required |
Compared with ST25DV02K and NT3H2111W0FHKH, RF37S114HTFJB uniquely combines ISO/IEC 15693-3 compliance, built-in antenna, AFI support, and industrial-grade temperature range - making it the only choice for high-volume, reader-centric, passive-only asset tracking in logistics and medical settings.

FAQ
Does RF37S114HTFJB require an external antenna?
No, RF37S114HTFJB integrates a tuned antenna within its 4 mm × 4 mm × 0.66 mm RFIDP package. This eliminates the need for external coil design, PCB antenna layout, or impedance matching - enabling immediate deployment on labels, inlays, or embedded substrates without RF engineering overhead. The RF37S114HTFJB is fully functional as shipped.
What memory organization does RF37S114HTFJB use?
RF37S114HTFJB provides 256 bits of user-programmable memory organized into eight 32-bit blocks (0x00–0x07), plus reserved bytes at 0x06 (AFI), 0x08–0x0A (lock bits), and a factory-programmed 64-bit UID. Each block can be individually locked using the Lock_Block command, and memory is accessible via ISO/IEC 15693 Read_Single_Block and Write_Single_Block commands.
Is RF37S114HTFJB compatible with NFC smartphones?
RF37S114HTFJB is NFC Forum Tag Type 5 compliant and interoperable with NFC smartphones supporting ISO/IEC 15693 - such as many Android devices with extended NFC mode enabled. However, it is not natively readable in default "NFC tap" mode on most phones; dedicated apps or developer-mode readers are required to access its full command set and memory structure.
What is the maximum number of tags RF37S114HTFJB supports in anticollision?
RF37S114HTFJB supports fast simultaneous identification of up to 50 tags per second under optimal reader and antenna conditions. This performance stems from its ISO/IEC 15693-compliant anticollision protocol and optimized response timing - making it suitable for high-density pallet or container scanning in automated logistics environments using the RF37S114HTFJB.
Does RF37S114HTFJB support write protection?
Yes, RF37S114HTFJB supports per-block write protection via the Lock_Block command. Lock bits reside at memory addresses 0x08–0x0A and permanently disable further writes to corresponding user blocks (0x00–0x07). Once locked, a block cannot be unlocked - ensuring immutability of critical fields like calibration data or serial numbers stored on the RF37S114HTFJB.
