NFC / RFID – Getting started
Near field communication (NFC) is a radio technology enabling bi-directional short range wireless communication between devices to make life easier and more convenient for worldwide consumers by simplifying transactions, digital content exchange and electronic device connection with a touch. This technology is adopted in smartphones and has a large infrastructure with millions of devices already in place.

RF430FRL15xH sensor transponder
The RF430 MCU platform – offering the industry’s lowest power, highly integrated single-chip NFC sensor transponder family for industrial, medical, wearables and Internet of Things (IoT) applications
By making NFC design easy, small, performance-rich and power-efficient, the RF430 MCU platform helps developers to design products that require an analog or digital interface, data-logging capabilities and data transfers to an NFC-enabled reader. The RF430 MCU 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.
Multiple low power modes
The RF430 MCU’s exceptionally low power consumption is created with a combination of a low leakage manufacturing process, design and architecture techniques, and software-managed power conservation capabilities (individual peripheral and five device level low power modes LPMs). LPMs combine clock gating and the use of low/high frequency clocks to deliver optimal current consumption, performance, autonomous peripheral operation, and minimal power-up latencies.
Productive low power modes allow:
- Take ADC Samples
- Transfer data throughout memory range
- Send and receive RF and serial communication
Our peripherals have been designed to give you maximum functionality and provide system-level interrupts, resets and bus arbitration at the lowest power. Many peripherals may function autonomously, thereby minimizing CPU time spent in active mode.
Devices integrated with:
- RF Frontend
- 14-bit Sigma Delta ADC
- I/O Ports
- 16-bit Timers
- Watchdog Timer
- Power Management Module
FRAM, or Ferroelectric Random Access Memory, is a type of nonvolatile memory that combines the speed, low-power, endurance, and flexibility of SRAM with the reliability and stability of flash to combine program and data into one unified memory space for the lowest power and easiest to use MCU architecture.
- Lower power
- Faster data throughput
- Virtually unlimited write endurance
- Designate any selection of memory as program or data
