Industrial Automation Functional Safety with Motor Control

Certified functional safety is mandatory in industrial applications due to the significant effects that can occur when safety checks are not in place. Learn more on implementing functional safety in motor control and discover how the IEC61508 certified RX functional safety solution can accelerate the certification process.

Wireless Connectivity

The RX Cloud and Bluetooth® Low Energy Solutions are ideal for wireless connectivity features for IoT equipment. The RX65N Cloud Kit makes development easier with the FreeRTOS operating system, and the upcoming FreeRTOS Over-The-Air (OTA) program instantaneously updates to the latest firmware, reducing the hassle of life cycle management. The RX23W is able to extend battery lifespan with its low power consumption and has both a target board and a Renesas Solution Starter Kit to shorten development time for Bluetooth applications.
