Renesas Announces RX Functional Safety Solution for Industrial Equipment

Renesas RXRenesas Electronics has recently announced “RX Functional Safety”, a new solution for industrial applications that reduces the complexity of IEC 61508 SIL3 certification, an international standard for functional safety.

Based on the RX family of microcontrollers (MCUs), the new solution provides advanced functional safety for industrial equipment, including functions for chip self-diagnostics, the SIL3-certified functional safety software and reference documents for users to develop the safety part of industrial applications. The complete functional safety support for industrial applications allows users to shorten the certification acquisition process by a year or more.

Featuring a dual-MCU configuration, RX Functional Safety will support all Renesas MCUs based on the RXv2 core to enable simple safety verification and a highly efficient diagnostics software. With the SIL3-certified software, the solution eliminates the need for users to develop functional safety software dependant to Renesas MCUs and allows them to focus on development of software for their own application components.

 “As robot-human interaction in industrial environments becomes more common, we have seen many customers struggling with the complex and often time-consuming challenge of functional safety, which is becoming a significant barrier for the industry,” said Akira Denda, Vice President, Industrial Automation Business Division, Renesas Electronics Corporation. “We are confident that our new RX Functional Safety solution will contribute to saving their time and resources and can dramatically accelerate the broad adoption of industrial equipment supporting functional safety.”

The new solution features the first SIL3-certified software that includes mutual diagnosis that presupposes a dual MCU structure and software isolation functions (safe and non-safe isolation functions) that isolate multiple application software programs from affecting each other. In situations where software changes occur in association with deployment to multiple versions, the software isolation function allows certification of only the software sections that have changed. This can significantly reduce the time required for recertification application and certification application itself, reducing the burdens involved in developing dual-MCU configuration systems.

Application software not related to functional safety – such as the system control software and safety monitoring software – can be embedded in a single MCU using the software isolation function, minimizing the need for additional devices for safety monitoring.

Availability

All four elements of RX Functional Safety are available now.
