The usage of complex Microcontroller Units (MCUs) in avionic systems
constitutes a challenge in assuring their safety. They are not developed
according to the development requirements accepted by the aerospace industry.
These Commercial off-the-shelf (COTS) hardware components usually target other
domains like the telecommunication branch. In the last years MCUs developed in
compliance to the ISO 26262 have been released on the market for safety-related
automotive applications. The avionic assurance process could profit from these
safety MCUs. In this paper we present evaluation results based on the current
assurance practice that demonstrates expected assurance activities benefit from
ISO 26262 compliant MCUs.Comment: Submitted to SafeComp 2018: http://www.es.mdh.se/safecomp2018
