Optimal combination of high-performance 32-bit RXv2 CPU core with improved DSP/FPU and low-power consumption.

The RX231 Group of devices leverages an optimal combination of a 32-bit RXv2 CPU core with improved DSP/FPU and low-power consumption technology to realize extreme power efficiency. High-performance digital filtering, floating-point operations, and other processing can be performed even in environments with low current supply capacity.The RX231 Group is equipped with capacitive touch sensor capabilities that combine high sensitivity with a high level of noise tolerance, as well as SD host interface, USB and CAN communication functionality and supported security function such as AES (Advanced Encrypt Standard) and true random number generator. These products are suitable for applications in industrial, home appliance, healthcare, smart meter, IoT, and other fields.
The RX230 Group is optimizing the specification by removing SD host interface, USB, CAN and security function from original RX231 Group and therefore is an ideal fit for cost sensitive general purpose market requirements.

Applications for the RX231 and RX230 include:

  • Industrial controller/sensor
  • Home appliances
  • Healthcare equipment
  • Office automation
  • Smart Meter
  • Building and Home automation
