Single-CAN 32-bit micro

27 February 2002 DSP, Micros & Memory

Fujitsu Microelectronics Europe's new MB91F364G is a 32 bit single-CAN interface device, targeted at applications including dashboard, body-electronics and information display applications demanding a small footprint. The MB91F364G is built around the established Fujitsu FR-core, a five-stage pipelined RISC core with 16 general-purpose registers and internal Harvard structure. The core is supported by 16 KB data RAM and a bit search unit. Program code and constant data are located within a 256 KB embedded flash ROM. This can be programmed in-circuit using a serial link or via parallel programmers. This device (in compact QFP120) has a host of on-chip peripherals including UARTs, I2C and serial synchronous interfaces, in addition to the CAN interface. Also, 16 bit reload timers, input-capture/output-compare units and realtime clock, as well as a 12-channel ADC and 8 external interrupts. The new on-chip 'background debug support unit' helps software development and debugging without use of in-circuit emulators.
