IAR enhances its development toolchain for the RH850 microcontrollers (MCUs) from Renesas Electronics Corporation. The RH850 architecture, used in automotive applications, now offers developers new development capabilities, including cloud-enabled licensing, container support, and CI/CD integration. The RH850 family targets automotive system applications such as electrification, advanced-driver assistance systems, and safety-critical electronic control units. The new updates provide developers with streamlined access to DevOps workflows, cross-platform builds, and scalable infrastructure options that drive both innovation and meet strict safety and compliance requirements, according to IAR.

This blogpost explains how we bypassed the 16-byte password protection of the debug on several variants of the RH850 family using voltage fault injection.
