9/30/2005 - Fujitsu Microelectronics Europe has announced a new series of 32-bit RISC (FR) microcontrollers specifically designed to fulfil the needs of next generation automotive applications. The MB91460 series is a 0.18µm successor to the successful MB91360 series. The transfer to a smaller geometry brings the advantages of lower power consumption, higher speed and the choice of additional new features on the same die size, or similar features on a smaller die.
The MB91460 controllers have been designed for automotive applications including body control, dashboard and infotainment. Fujitsu will also release further variations of this family, with additional peripherals, enabling designers to address an even wider range of applications.
The first production part is already available for sampling. This is a ROMless device for infotainment, which will be ready for production by the end of 2005. The second product, a 1MB embedded flash device featuring 64kB on-chip RAM, 3 CAN interfaces and many more peripherals, has been developed especially for use in cluster applications, and will first be sampled to customers in late 2005.
The MB91460 series is built on a 0.18µm version of the proven FR CPU core. This allows simple code portability and offers programmers the ability to write customised code in a familiar format to Fujitsu's 'Softune Workbench' development environment.
The 0.18µm technology allows the integration of up to 4MB next generation Flash, and up to 128kB RAM is supported, which is over 5 times the maximum capacity of the previous MB91360 series. This Flash memory is based on Fujitsu's proven Flash technology. On-chip pre-fetch and cache mechanisms ensure best possible performance from the memory, which is connected to both the I-bus and F-bus.
One of the main differences between the MB91460 series and its previous generation is the wider range of inputs and outputs available. I2S, MediaLB and FlexRayTM will all be included in the new series, as will up to six CAN I/Os and full 5V capability for I/Os and analogue interfaces. USB and Ethernet are currently under discussion.
Other improvements offered in this new series are a choice of I/O drive strengths, 2mA, 5mA or SMC drivers of 30mA. Various input levels are also included, such as automotive, CMOS Hysteresis and TTL. An external bus-interface with support for burst/page mode memories and FCRAMTM/SDRAM is also offered for the first time.
The microcontrollers will function over the standard automotive operating temperature range of -40 to +85°C and versions will also be available that operate over the extended automotive temperature range of up to 125°C. The new series will initially be available in QFP-176 and QFP-208 packages.
This new series complies with all relevant standards, including ISO9000/TS16949 /AEC-Q100, and fulfils all environmental standards, being RoHS-compliant and lead free. Full application and design support is offered throughout Europe by Fujitsu Microelectronics Europe in Frankfurt, where the company's European Microcontroller Design Centre is based.
