Fujitsu Introduces FlexRay-Based MB91F465X Driver-Assistance Controller



    SUNNYVALE, Calif., March 28 /CNW/ -- Fujitsu Microelectronics America,
Inc. (FMA) today introduced the FlexRay(TM) controller, the MB91F465XA.
Designed for driver-assistance applications, the MB91F465XA is built around a
Fujitsu FR 70 32-bit CPU, with an internal clock speed of 100MHz and voltage
range of 3.0V to 5.5V. Based on the E-Ray core licensed from Robert Bosch
GmbH, the device uses VHDL code certified by TUV Nord, supports 2-channel and
FIFO operations, and supports 218 different identifiers by providing more than
8kBytes of message buffer memory.
    The controller enables implementation of the FlexRay protocol without the
need for companion devices, providing an excellent, easy-to-use solution for
automotive OEM, tier-one and third-party companies delivering tools and
software for automotive applications or test equipment. The MB91F465XA
complements standard automotive buses, including the Controller Area Network
(CAN) and Local Interconnect Network (LIN). FlexRay-based technology provides
approximately 10 times the throughput of CAN, and is expected to gradually
replace CAN as automakers and their suppliers adopt x-by-wire solutions. In
addition to the two-channel FlexRay bus interface, one I2C, two CAN and three
LIN-USART interfaces are incorporated onto the controller, enabling
communication with all automotive bus systems.
    The MB91F465XA is a member of the MB91460 series, so it is designed
specifically to let engineers re-use their software across different family
members and applications. The device operates from a single supply ranging
from 3V to 5.5V. Internal frequencies of up to 100MHz are generated via the
on-chip PLL using external 4MHz quartz crystals as the clock input. A total of
544KB of Flash memory with read-out protection and 32KB of RAM is available,
making the MB91F465XA meet AUTOSAR (AUTomotive Open System ARchitecture)
requirements.
    Other features include hardware watchdog, 17-channel 10-bit ADC, reload
timer, stopwatch function, and an RTC module that can operate on external 4MHz
or 32KHz quartz crystals.

    
    Key Component in Fujitsu's "FlexRay Made Easy" Program
    
    The new controller is part of Fujitsu's "FlexRay Made Easy" program,
which includes the hardware, driver and operating systems software,
application software, development tools, and support required for application
development, according to Akio Nezu, senior manager, Embedded Solutions
Business Group, Fujitsu Microelectronics America. "This new FlexRay MCU
represents the latest step forward in our program to deliver complete FlexRay
solutions as this important new communications standard emerges in the
automotive market."
    Fujitsu, an active member of the FlexRay consortium since 2002, is also a
member of AUTOSAR and Jaspar, the standardization organizations for the
automotive industry. Through these organizations, FlexRay-related product
development is accelerating.

    
    Pricing and Availability
    
    Samples of the MB91F465XA are available in 100-pin FPT packaging with
prices starting at $8.27 each.
