SUNNYVALE, Calif., March 28 /PRNewswire/ -- 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.
