Datasheet
FlexRay
The Fujitsu
The new FlexRay protocol opens the door for future
automotive applications (such as x-by-wire) that require
enhanced safety features compared to current automotive
network systems.
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.

(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.
