CIC310 - FlexRay TM Companion IC
Smar t Co mpanion ICs for
Seamless Scalabil ity of Microcontrolle rs
CIC310 is a FlexRay TM Co mmunication Co ntroller
Co mpanion IC fo r Auto motIve Embedded Co ntrol
T A R G E T E D A T safety critical automotive applications such as
x-by-wire systems (brake-by-wire, steer-by-wire, etc.), active and passive
safety systems, collision avoidance systems, driver assistance systems and
automotive applications requiring high communication bandwidth such as
powertrain management, chassis management network etc. With a gross
data rate of 10 Mbit/s, FlexRayTM delivers approximately 20 times higher net
bandwidth than the CAN protocol currently used in advanced automotive
control applications.
F O R S E A M L E S S extension of the microcontroller by supporting
Micro-Link Interface (MLI) standard, enabling a look and feel from software
point of view almost like it is an integrated module. A de-multiplexed
8/16-bit parallel Interface (XMU) is provided as an alternative for
microcontrollers that do not support MLI yet. An SPI interface providing an
alternative host interface for microcontrollers having a low pin count and
moderate FlexRayTM bandwidth requirements. A DMA, data processing, and
data triggering unit to unload the host processor, provide application
specific functions (protocols), and implement a safety shell (firewall).
