SIL3-certified software is released for RA and RX microcontrollers
Functional safety software that meets the IEC 61508 standard for Renesas Electronics’ RA and RX families of microcontrollers (MCUs) are now available. Renesas offers IEC 61508 SIL3-certified self-test software for both Arm Cortex-M23 and -M33-based MCUs. Renesas also announced the IEC 61508 SIL3 certified PROFIsafe Application Software for RX MCUs. Renesas added that it is the industry’s first semiconductor supplier to offer these hardware-software solutions.
When building a safety critical system using an MCU, it is required to provide device-level diagnostics. With Renesas’ SIL3 certified Self-Test Software, customers can leverage IEC 61508 certifications for the MCUs CPU, ROM and RAM when certifying the overall system. Renesas Self-Test Software kit currently supports Arm Cortex-M23 and -M33-based RA2, RA4, and RA6 series MCUs.
To address the need for safe network communication in applications that use industrial Ethernet, Renesas introduced the PROFIsafe Application Software. The SIL3-certified PROFIsafe Application Software Kit realises PROFIsafe functionalities on ProfiNet slave devices and eliminates the certification step for network communications. It works with Renesas’ certified SIL3 System Software kit for RX MCUs. The PROFIsafe Application Software supports RX200, RX600 and RX700 series MCUs. Self-Test Software is already available for RX MCUs.
Both the Self-test Software for the RA Family and the PROFIsafe Application Software for the RX Family have been certified by TÜV Rheinland.
Both the IEC 61508 SIL3-certified Self-Test software kit and PROFIsafe Application Software kit are available today. In addition, Renesas offers reference documentation, an evaluation board for the RX family, and an IEC 61508 Certification Kit for RX compilers.
Renesas Electronics delivers trusted embedded design innovation with complete semiconductor solutions that enable billions of connected, intelligent devices. It produces microcontrollers, analogue, power and SoC products, for a broad range of automotive, industrial, infrastructure and IoT applications.
