Fujitsu to Embed Bosch's FlexRay IP into Automotive Control MCUs

1/27/2005 - Fujitsu Limited announced the acquisition of a license to use the FlexRayTM (*1) Communication Controller IP-Module from Robert Bosch GmbH. The license will allow Fujitsu to embed precision-designed FlexRay IP into its automotive control MCUs (*2) and quickly bring to market high-quality next-generation products.

Fujitsu currently offers MCUs with CAN (*3) and LIN(*4) interface protocols for various automotive control applications, including body and comfort electronics, climate control, dashboards, navigation, safety and sensor electronics, power-train, and chassis electronics. In-car control systems of the future will require faster and more reliable data transfer as data volume increases and systems continue to become more complicated. By licensing FlexRay IP from Bosch, Fujitsu will be able to quickly introduce new automotive control application products with even higher-speed data transfer and reliability.

The FlexRayTM IP core features data transfer rates up to 10 megabits per second (10Mbps) and employs a bus system that pre-defines necessary time slots within the transmission bus to realise higher reliability. Embedding FlexRay IP into a single-chip MCU will further advance the performance and range of automotive electronic control applications.

Fujitsu plans to offer an FPGA (*5) prototype board that will enable customers to incorporate FlexRay into their products with ease. The company also intends this year to offer FlexRay as an ASSP (*6) standard IP solution, which will make it possible for customers to utilise FlexRay IP with other CPU cores as part of their systems. In early 2006 the first MCU with embedded FlexRay IP will follow. The embedded solution will be based on the 32-bit Fujitsu FR core (*7).

Along with its CAN and LIN interface offerings, the new high-speed FlexRay equipped products will enhance and extend Fujitsu's line-up of highly reliable MCUs for automotive control applications.

Glossary and Notes
