Fujitsu Microelectronics America Introduces 32-Bit CAN Bus Microcontroller Family with Two MCUs Designed for Automotive and Industrial Applications

New ICs include on-chip peripherals, simple analog sensor connectivity

San Jose, CA, June 4, 2002 — Fujitsu Microelectronics America, Inc. (FMA) today expanded its extensive microcontroller family, introducing two new 32-bit microcontrollers with FULL-CAN (Control Area Network) bus interfaces and single voltage flash memory.

The new MB91F367G and MB91F368G are designed specifically for automotive and industrial-control applications. Based on Fujitsu's proven 32-bit microcontroller technology, the MCUs include a variety of on-chip peripherals including UARTs, I2C and serial synchronous interfaces, 16-bit reload timers, input-capture/output-compare units and a real-time clock. The microcontrollers also incorporate a 10-bit resolution, 8-channel ADC and eight external interrupts, so designers can connect a wide range of analog sensors. Each provides the same basic functionality, resources and pin-out; the MB91F368G adds a 32kHz clock input for precise real-time clock reference.

"The new FR™ microcontrollers offer high-performance solutions for automotive and industrial applications that require two CAN controllers," said Sardar Haddad, marketing director of FMA's Embedded Processor Group. "The highly integrated MCUs are great additions to our CAN product portfolio, and further enhance Fujitsu's leadership position in CAN microcontrollers."

Based on Fujitsu's Established FR RISC Core
These new devices are built around Fujitsu's FR architecture, a five-stage pipelined RISC core that is supported by 16kB data RAM and a bit-search unit. Program code and constant data are located within a 512kB embedded Flash ROM, which can be programmed in-circuit, using a serial link or via parallel programmers. The Flash memory in the MCUs provides a minimum 10,000 write/erase cycles.

The MCUs integrate a clock modulator unit, which reduces noise by spreading the energy of the IC over a wide frequency range. The clock modulator reduces electromagnetic emission, so EMI-approval standards can be met without extensive re-designs.

Both devices share the software modules and operating systems with Fujitsu's MB91360G series microcontrollers, for which libraries are available. The new MCUs are ported for the OSEK operating system, which is now standard for all vehicle-control systems. An on-chip background debug support unit helps designers develop and debug final applications with no need for in-circuit emulators.

Price and Availability
The MB91F367G and MB91F368G are now available in compact 120-pin QFPs. Prices begin at $19.80 each in 10,000-unit quantities. An evaluation device, the MB91FV360, is also available.
