The RF430FRL15xH device is a 13.56-MHz transponder chip with a programmable 16-bit MSP430 low-power microcontroller. The device features embedded universal FRAM nonvolatile memory for storage of program code or user data such as calibration and measurement data. The RF430FRL15xH supports communication, parameter setting, and configuration through the ISO/IEC 15693, ISO/IEC 18000-3 compliant RFID interface and the SPI or I²C interface. Sensor measurements are supported by the internal temperature sensor and the onboard 14-bit sigma-delta analog-to-digital converter (ADC), and digital sensors can be connected through SPI or I²C.

The RF430FRL15xH device is optimized for operation in fully passive (battery-less) or single-cell battery-powered (semi-active) mode to achieve extended battery life in portable and wireless sensing applications. FRAM is a nonvolatile memory that combines the speed, flexibility, and endurance of SRAM with the stability and reliability of flash, all at lower total power consumption.
