DESCRIPTION

Via its new MB91F364, Fujitsu now offers a 32 bit single CAN interface device for applications demanding a small footprint. This new device satisfies today's requirement for higher performance coupled with 'platform'-based solutions, where many compatible devices are used for a wide variety of applications. The device has a host of on-chip peripherals including UARTs, I²C and serial synchronous interfaces, in addition to the CAN interface, 16 bit reload timers, input-capture/output-compare units and real time clock, as well as a 12-channel ADC and 8 external interrupts. This wealth of peripherals enables the MB91F364 to be used in a wide range of applications from automotive to industrial. Particularly important for single-chip applications is the new on-chip 'background debug support unit', which helps software development and debugging of the final application without the use of in-circuit emulator systems. This unit provides a number of instruction and data-breakpoints including mask and range-functionality. Used together with the appropriate background software, this unit speeds up application development and offers the ability to debug in the final application.
