The protocol was developed for providing fault-free communication between various electronic components of communication system. Such a system, which consists of finite quantity of electronic components capable of exchanging data, is called distributed system. It is expected to be the new de facto standard, combining the advantages of time-triggered and FTDMA communication [2]. FlexRay ready products, initially Freescale will develop a FlexRay 2.0-compliant module that can be used for license, stand-alone communications controllers and integrated 16- and 32-bit microcontrollers.
