Embedded 32 Bit RISC Solutions from Fujitsu

Introduction

Fujitsu’s own 32-bit RISC CPU architecture FR has a long history and is used in a large number of Microcontrollers for automotive, industrial as well as consumer applications. It’s a based on a powerful Harvard architecture with separated instruction and data bus. An optimized instruction set assures low code size densities and high execution speed. The latest generation FR81 is a further improved CPU core with an enhanced instruction pipeline for reduced branch penalty, with FPU for accelerated arithmetic instructions and more functional safety features.

With the ARM Cortex M3 based Microcontroller family FM3, Fujitsu offers also MCUs with an established standard CPU core. Cortex M3 is ideally suited for embedded applications which require medium performance above typical 16-bit MCUs. It’s the, significantly enhanced, continuation of the ARM7 architecture. The FM3 family consists of many software and pin compatible devices, thus offering a scalable Microcontroller platform.

Fujitsu's latest addition to its automotive 32-bit portfolio is a high end line-up based on the
ARM® Cortex™-R4 core and Fujitsu's 90nm embedded flash technology.
The first devices are targetting automotive instrument clusters and together with the Indigo and Emerald GDC families offer a scalable line-up to cover all cluster categories.
