FlexRay™ networking is a next-generation automotive communication protocol featuring high bandwidth, determinism and fault tolerance. The MFR4310 stand-alone FlexRay controller eases the integration of FlexRay communication in applications using MCUs without an embedded FlexRay controller, and complies with FlexRay Consortium Specification v2.1A. The MFR4310 controller is designed to communicate directly with the S12X family of 16-bit MCUs, and the MPC500 and MPC5500 families of 32-bit MCUs.
