OVERVIEW

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. It is equipped with as  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. These products are suitable for applications in industrial, home appliance, healthcare, smart meter, IoT, and other fields.

 

The RX230 Group has more simplified configuration of RX231 by removing SD host interface, USB, and CAN,  which is optimized for general purpose market equipment requiring 5v power supply support, external bus, or  high DSP/EPU operational performance at low power consumption.

 

Renesas offers comfortable Reference solution which enables to immediately incorporate RX231's features such as security function, encryption function, HMI (Human Machine Interface), and touch key into users applications.

Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
