FlexRay1 is a high speed, time triggered and fault tolerant communication protocol, which was specified to meet the requirements of safety-critical automotive applications. The achieved maturity of FlexRay encourages the implementation on silicon. The CIC-3102 device is a standalone controller provided by Infineon Technologies. It runs the wide spread E-Ray3 IP from Bosch.
A complete communication node for FlexRay requires additional devices for the physical layer and the application part. The CIC-310 can communicate with a host controller via three different interfaces micro link interface MLI, serial synchronous interface SSC, external bus XMU. Its physical layer interface corresponds to the FlexRay specification. The CIC-310 provides features like intelligent move engines to maximize the achievable data rate as well as to minimize the workload of the host. Therefore, the CIC-310 allows a very flexible and efficient way to build and operate FlexRay nodes.
