Fujitsu Microelectronics Europe (FME) has announced the availability of a new 32bit microcontroller (MCU), the company's first to feature an embedded FlexRay interface. Aimed at automotive OEM, tier one and third-party companies delivering tools and software for automotive applications or test equipment, the MB91F465XA enables implementation of the FlexRay protocol in a single-chip solution without the need for companion devices. The MB91F465XA is the latest addition to Fujitsu's growing family of FlexRay MCUs.

Based on the E-Ray core licensed from Robert Bosch, the MB91F465XA uses VHDL code certified by TUV Nord.

The device supports two-channel and FIFO operations, and with more than 8Kbyte of message buffer memory, up to 128 different identifiers can be supported.

Interfaces, in addition to the two-channel FlexRay bus interface, comprise one I2C, two CAN and three LIN-USART interfaces enabling communication with all automotive bus systems.

Packaged in a compact, RoHS-compliant 100-pin LQFP, this device is ideally suited to automotive applications such as driver-assistance systems.

The FR (Fujitsu RISC) MCU, series MB91F465XA is a member of the MB91460 series which follows Fujitsu's MCU family concept that allows design engineers to re-use their software across different family members.

MB91F465XA operates from a single supply ranging from 3.0 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.

544Kbyte of Flash memory with read-out protection and 32Kbyte of RAM, make the MB91F465XA well-suited for Autosar requirements.

Other features include: hardware watchdog, 17-channel 10bit ADC, reload timer, stopwatch function, and an RTC module that can operate on external 4MHz or 32kHz quartz crystals.

Engineering samples will be available in February 2007 and will be accompanied by a full set of development tools such as starter kits, and hardware and software debugger.
