Fujitsu Introduces New High-Performance, 32-Bit Microcontrollers with CAN Support for Advanced Automotive Applications



New MCUs Feature Embedded Flash Memory and Industry's Highest 80MHz Clock Speeds

Convergence 2006, DETROIT, Oct. 16 / - Fujitsu Microelectronics America, Inc. (FMA) today introduced three new high-performance, 32-bit microcontrollers for next-generation automotive applications. The new ICs, part of Fujitsu's MB91460 series, include the MB91F464AA and MB91F465KA, which have been designed for automotive body control applications. The third MCU, the MB91F467RA, was designed for on-board entertainment and information systems. All three MCUs incorporate Controller Area Network (CAN) interfaces and are available now.

The MB91F465KA and the MB91F464AA serve door, seat, air conditioning and other vehicle body controls. Both include a CAN channel, 32 CAN message buffers and five UART channels that comply with the Local Interconnect Network (LIN) standard.

Designed for car navigation, audio, and other information system controls, Fujitsu's new MB91F467RA includes two CAN channels, either 32 or 64 CAN message buffers, and seven LIN-compliant UART channels. LIN interfaces are used for vehicle door, mirror, and wiper controls.

All the new MCUs run at clock speeds of up to 80MHz, the fastest in the industry, and have embedded Flash memory.

"Automotive systems that use CAN for body and driving control have become widespread," said Akio Nezu, senior marketing manager for the Embedded Solutions Group at Fujitsu Microelectronics America. "In addition, preventive safety technologies using video processing and other means, intelligent transport systems (ITS), and systems to improve environmental performance are being analyzed for use in vehicles. These types of systems require microcontrollers like the new models we are introducing today that can process information in real time from a wide range of peripheral components."

Fujitsu offers development chips and tools supporting the MB91460 series, enabling all MCUs, including these new models, to be developed using the same platform.

Fujitsu plans to augment its line of microcontrollers for next-generation, on-board vehicle systems, with new models planned for dashboard and FlexRay controls.

Pricing and Packaging

The MB91F464AA, which comes in 100-pin LQFP packages, is priced at $8.52 each in volume. The MB91F465KA is available in 120-pin LQFP packages and is priced at $9.73 each in volume. The 176-pin LQFP MB91F467RA costs $17.04 each in volume.
