Fujitsu Microelectronics Partners with Elektrobit

Fujitsu Microelectronics Limited (FML) has teamed up with Elektrobit (News - Alert), Finland, to develop new MicroController Unit (MCU) drivers for Fujitsu's MB91460 series of 32-bit microcontrollers, said an announcement from Fujitsu Microelectronics America (FMA (News - Alert)).

Fujitsu Microelectronics develops advanced microcontrollers for automotive applications. Fujitsu's MB91460 series of 32-bit microcontrollers are compatible with Automotive Open System Architecture (AUTOSAR) version 2.1.

 

AUTOSAR is a standards consortium for automotive electronics and software. Fujitsu Microelectronics joined AUTOSAR as a premier member in 2005.

 

Elektrobit is a provider of software and hardware solutions in automotive embedded systems. The company entered into a strategy partnership with Fujitsu Microelectronics in 2007. The new drivers are part of Elektrobit's EB tresos family.

According to Fujitsu Microelectronics, the new MB91460 series of 32-bit microcontrollers offer a high degree of code reusability and maximum efficiency for application designs.

 

Fujitsu Microelectronics and Elektrobit have created two AUTOSAR-compatible drivers. The first driver is designed for the MB91F467DA dashboard controller, an MCU with a Controller Area Network (CAN) interface. It is used in automotive instruments panels to drive meter needles and control odometers, trip meters, warning lights and other information displays.

 

The other driver is for the MB91F465XA, a FlexRay 2.1-compatible MCU for sophisticated controls that provide communication speeds up to 10Mbps with high reliability.

 

FlexRay networking applications are now included in AUTOSAR 2.1 specifications, enabling users of Fujitsu Microelectronics MCUs and the new driver to gain maximum benefits of FlexRay.

Akio Nezu, senior manager, embedded solutions group, Fujitsu Microelectronics America, said, “Electronic control technology is becoming pervasive in the new generation of onboard vehicle systems. As a result, the number of electronic components is increasing and the software that controls these components is becoming more complex, creating the potential for higher costs for manufacturers of vehicles and electronic control unit suppliers. By deploying AUTOSAR standards, application software can be reused on any microcontroller, enabling efficiencies and cost savings for users.”

 

“Incorporating the FlexRay networking standard into the AUTOSAR specification leverages these benefits for leading-edge application designs,” Nezu added.

Fujitsu Microelectronics and Elektrobit plan to continue to provide drivers that are compatible with the latest upgrades of AUTOSAR standards.
