The first applications that will deploy FlexRay are chassis and powertrain applications, preparing the ground for the first x-by-wire applications. Fujitsu is working to support the development of next-generation automotive-by-wire applications. A fully integrated FlexRay microcontroller MB91F465X, as well as the FlexRay application-specific standard product (ASSP) MB88121C, are available from Fujitsu. The ASSP device provides generic host interfaces for a wide variety of host processors. The FlexRay integrated microcontroller is manufactured in 0.18μm embedded Flash technology, enabling it to run at more than 100MHz system clock. To fit the requirements of automotive applications, the devices feature full 5-volt operation capabilities for I/Os, analog parts and supply voltage, while the core itself will run at 1.8 volts from an integrated regulator.
