Fujitsu Microelectronics Ltd has released a new driver for its MB91460 series of high-performance 32bit automotive MCU, jointly developed with Elektrobit Corp. (EB) and compatible with Release 2.1 of AUTOSAR.

The companies jointly developed two drivers compatible with AUTOSAR 2.1, one for the dashboard-control MCU MB91F467DA, and one for the FlexRay 2.1 MCU, MB91F465XA. When used with Fujitsu's MCU, the new drivers will offer customers a greater degree of code reusability for automotive onboard applications already developed, and greater efficiency when developing automotive software.

Preparing the next generation of onboard systems in cars, as electronic control technology becomes more pervasive and the number of electronic components increases, the software that controls these components is becoming more complex and larger, leading to mounting costs for manufacturers of vehicles and electronic control units. AUTOSAR is a standards consortium for automotive onboard systems software dedicated to addressing this problem by creating a common specification for onboard software. The recently-published AUTOSAR Release 2.1 specification encompasses FlexRay, the next-generation in-vehicle networking standard.

Fujitsu became a premium member of the AUTOSAR organization in 2005 and has taken an active role in the development of onboard MCUs. In 2007, the company formed a strategic partnership with EB, a provider of software for automotive onboard systems. The companies worked together to develop a version of EB's "EB tresos" software for Fujitsu's MB91460 series of MCUs, with both companies agreeing to distribute an AUTOSAR-compatible driver.

Based on its strategic partnership agreement with EB, Fujitsu will continue to provide drivers compatible with the latest upgrades to the AUTOSAR standards for the mid- to long-term future.
