描述
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 implements the industry's top level communication security and encryption functions, high sensitivity high level of noise tolerance capacitive touch sensor capabilities, as well as SD host interface, USB and CAN communication functionality. These products are suitable for applications in industrial, home appliance, healthcare, smart meter, IoT, and other fields.
Renesas offers a reference solution which enables users to immediately incorporate the RX231's features such as security function, encryption function, human machine interface (HMI), and touch key into their applications.
