32-bit Microcontroller with Built-in FlexRay for Automotive Control Systems FR Family MB91F465XA

In recent years, X-by-Wire technology, which is used to electrically control conventional hydraulically controlled systems, has been receiving increased attention for its use in next-generation automotive systems. Automobile data has been increasing in volume and becoming more and more complex. As such, faster and more reliable networks are necessary. In this context, FlexRay shows great promise as a next-generation automotive network. The FlexRay microcontroller“MB91F465XA”that FUJITSU has developed has a built-in 32-bit RISC, FR core to increase the maximum operation frequency to 100MHz. Its high versatility and compact specifications will allow a flexible shift from the various existing CAN bus systems to FlexRay. Furthermore, it can be applied as a gateway between conventionally used CAN and FlexRay. Fig.1 shows the target applications of FlexRay. Product Features
