NFC and RFID Device Families:
Transceiver devices: TRF796xA / TRF7970A
• Industrial: NFC-enabled access, M2M communication
• Medical: Product identification, authorization consumables
• Smart-meter: Pre-payment, device configuration
• Automotive: Communication interface to smartphone
• Consumer electronics: Pairing via NFC, peripherals, toys
• Retail: POS contactless payment
The TRF79xxA family of NFC/RFID transceivers support all the popular 13.56MHz air-interface-based protocols, standards and specifications commonly in use today, around the world. The devices can also be used in AFE mode for non-standard applications. Initial device choice would be based on the application or end equipment NFC/RFID requirements. This family of devices allows for true scalable platform development as they are pin-to-pin compatible.
The TRF796xA devices provide High-Frequency (HF) RFID reader/writer functionality for proximity and vicinity applications while the TRF7970A device brings the superset functionality of NFC to the TRF79xxA family, adding the features of card emulation (using NFC-A or NFC-B) and peer-to-peer communications (using NFC-A or NFC-F, as initiator or target) to the reader/writer functionality for ISO 14443A/B, FeliCa and ISO 15693. Device configuration is register based, which allows an end application microcontroller to fine tune parameters or change protocols/modes, as required.
NFCLink Library: Firmware / Software solution
The NFCLink is an industry-proven modular firmware/software solution from hardware level up to operating system (OS) API to support TI’s family of TRF79xx NFC transceiver devices. With NFCLink, TI provides embedded standalone firmware and NCI standardbased interface to Android, Linux and Windows operating systems which simplifies and streamlines the development of all NFC operation modes across TI’s entire embedded processing portfolio of MSP430™ microcontrollers (MCUs) and ARM®-based MCUs and processors.
From highly energy-efficient systems to high-performance devices, NFCLink provides the developer/integrator a complete and proven high-quality NFC firmware/software bundle to use with TI’s broad portfolio of embedded processing products to accelerate customers time to market by minimizing the in-depth protocol and device knowledge required for NFC applications. Offered as a standalone library for download, the modular software architecture enables selection of features and functions based on the application requirements. This professionally maintained NFC stack also supports extended functionalities above the ISO standard for non-standard, proprietary card systems through the flexibility of the TRF79xxA.
RF430: Dynamic transponders
The RF430 family of dynamic transponder devices offers unique support for highperformance, feature-rich NFC wireless sensor applications and cost-optimized NFC interface applications like NFC connection handover for an alternative carrier like Bluetooth® and Wi-Fi® for a broad range of consumer electronics, white goods and medical devices. Both product lines provide NFC functionality with an optimized power management architecture either through harvesting RF energy or powered through a separate battery power source for ultra-low-power applications.
The RF430FRL152H is a fully programmable device providing an NFC RF front-end and an I2 C/SPI interface along with a sigma-delta ADC, high-performance instrumentation amplifier and on-board non-volatile FRAM memory for true data logging applications. Unlike other fixed-function devices currently in the market, the built in 16-bit MSP430™ microcontroller allows a programmable option through the universal FRAM capability for handling a variety of sensors and external memory as well as custom processing of the sensor-collected data.
The unique capability of the RF430FRL152H device enables standalone applications without the need for an external host processor. The RF430CL330H device is a cost-optimized Dynamic NFC Tag Type 4 device supporting the NFC connection handover requirements for Bluetooth and Wi-Fi pairing and authentication through an optimized serial interface. The RF430CL331H enables data steaming and transfer of large data files limited only by the memory capacity of the host controller. Read caching, prefetching, and write automatic acknowledgment features allows for greater data throughput so that it can be used as a general NFC interface / service interface for configuration and FW updates.
Tag-it™ HF-I: Static transponders
Texas Instruments Tag-it HF-I family of transponder products (inlays, encapsulated devices and wafers) consist of 13.56MHz HF devices that are compliant with NFC Tag Type 5 ISO/IEC 15693 and ISO/IEC 18000-3 (Mode 1) global open standards. Data like text or uniform resource identifier can be stored in the tag memory according to the NFC Forum specified NFC Data Exchange Format (NDEF). With the RF37S114 a 4 mm × 4 mm transponder with integrated antenna Texas Instruments is offering one of the smallest transponders in the market. The Tag-it HF-I transponder product offerings are well suited for a variety of applications including but not limited to: product authentication, supply chain management, asset management and ticketing.
