Fujitsu’s 32-bit Microcontroller to Integrate Automotive CAN Networks

Fujitsu Microelectronics Asia Pte Ltd (FMAL) has unveiled the new MB91F467BA high-performance 32-bit microcontroller from its MB91460 Series for automotive applications.

The new microcontroller has the ability to integrate several in-vehicle Controller Area Networks (CAN).

According to Fujitsu, with its six-channel CAN controller, the most channels in the industry, it is possible to realize interconnection and gateway functionality among CAN networks of different speeds, or between CAN and FlexRay2 allowing for control over combinations of various in-vehicle networks.

The MB91F467BA microcontroller has 1 Mb of Flash Memory and a 32-channel A/D Converter as its base configuration, and can also be used as the primary microcontroller for automotive dashboard and automotive body control.

In recent years, systems using CAN for automobile body and handling control have been widely adopted, even as the in-vehicle network speeds increase and connecting equipment become very diverse. Consequently, there is an expanded need for greater control over the entire in-vehicle network within the Electronic Control Unit (ECU) 3 especially so for body control ECUs. ECUs control each electrical component in the network.

In response to these developments, Fujitsu created the MB91F467BA microcontroller with a top processing speed of 100MHz, and offers not only body control but gateway functionality as well.

The MB91460 Series of microcontrollers feature a common FR60 CPU core and peripheral functions. The series also boasts a common development chip that reduces software development costs and reuses customer resources.

Key Features of the new solution includes; Most Channels in the Industry with a 6 Channel CAN Controller, Allowing In-vehicle Network Integration, MB91460 Series Common Development Chip, Reduces Software Development Costs, Realized Single Power Supply Operation.
