What is the RF430FRL15xH?

The RF430FRL15xH devices are highly integrated, fully programmable, RFID / NFC sensor transponders. This system-on-chip (SoC) family combines an ISO 15693-compliant RFID / NFC interface with a programmable ultra-low-power microcontroller (MCU), nonvolatile FRAM, an analog-to-digital converter (ADC), integrated temperature sensor, and a SPI or I2C interface.

The dual-interface RF430FRL15xH NFC sensor transponder is optimized for use in fully passive (battery-less) operation for on-the-spot measurements using RF energy harvested from an NFC-enabled reader or smartphone, or semi-active modes for battery-supported data logging in FRAM to achieve extended battery life in a wide range of applications.

Features and benefits of the RF430FRL15xH NFC sensor transponders:

  • Supports wireless communication through the ISO/IEC 15693 and ISO/IEC 18000-3 compliant RFID interface.
  • Optimized for 1.5-V single-cell-battery-powered designs or battery-less designs that harvest energy from the RF field generated from an NFC reader. Intelligent power management includes a battery switch to ensure long battery life.
  • 14-bit sigma-delta ADC with ultra-low input current, low noise, and ultra-low offset enables developers to connect up to three additional external sensors in addition to the integrated temperature sensor.
  • SPI or I2C interface can support digital sensors or connect the device to a host system.
  • Application code embedded in ROM manages RF communication and sensor readings to provide the ultimate flexibility in configuring the device. Developers can configure sampling rates, measurement thresholds, and alarms.
  • Universal nonvolatile memory (FRAM) allows data storage as well as extension and adjustment of application code.
  • Integrates a 16-bit ultra-low-power programmable MSP430™ CPU core that is supported by a robust ecosystem of development tools.
  • Fully integrated into the TI Code Composer Studio™ (CCS) and IAR Embedded Workbench® integrated development environments (IDEs).
