Datasheet

A flexible, high frequency 13.56MHz sensor transponder family, claimed to be the industry’s first, has been released by Texas Instruments. The RF430FRL15xH SoC family combines an ISO 15693-compliant NFC interface with a programmable MCU, non-volatile FRAM, an ADC and SPI or I2C interface.

To achieve extended battery life in a wide range of consumer wearables, industrial, medical and asset tracking applications, the transponder is optimised for use in fully passive (battery-less) or semi-active modes.The device features non-volatile FRAM, which combines the speed, flexibility and endurance of SRAM with the stability and reliability of flash while providing the industry’s lowest power consumption and virtually unlimited write cycles. FRAM enables easy configuration of the transponder and sensors, allowing developers to create products that can quickly store sensor data.

The RF430FRL15xH allows developers to design products that require an analogue or digital interface, data-logging capabilities and data transfers to an NFC-enabled reader. The transponder acts as a sensor node for these applications and generates an IoT-ready solution when an NFC-enabled device pushes the data to the cloud.

The RF430FRL15xH transponder is available now, priced at $2.50 and sold in 1,000 piece quantities. Other versions include the RF430FRL153H (without SPI/I2C) and the RF430FRL154H (without sigma-delta ADC).

TI offers an evaluation board for use with the RF430FRL15xH transponder. The RF430FRL152HEVM board can be powered with a battery, USB or by harvesting RF energy from a nearby NFC-enabled reader or smartphone. Both the transponder and evaluation board are available now. The board is available now and priced at $19.90.
