Fujitsu ups performance of 32bit, ARM Cortex based mcus

Designed for applications that require advanced, high speed computing performance, including inverters, servomotors, PLCs and other industrial equipment, the FM4 family is said to offer increased computational performance and enhanced peripheral functionality. In addition, Fujitsu claims the mcus deliver greater processing power, with half the per-frequency power consumption of the FM3 family. A total of 84 devices will be added to the range. Samples will be made available from July. Wolf Fronauer, Fujitsu's marketing manager, said: "The new FM4 family offers customers even more performance and peripheral functionality. This means they can select highly optimised embedded mcus that are an exact match for virtually any set of embedded application requirements, all without leaving the FM ecosystem. "Later this year, we will launch the FM0+ family: based on ARM Cortex-M0+, this rounds off the portfolio by adding support for low cost and ultra low power applications." The mcus in the FM4 family can operate from 3 or 5V power supplies, and offer a range of memory options that includes sram, nor flash, nand flash and sdram. The devices feature an ultra wide bus for on chip flash memory that enables read access with no cpu wait state, so as to accelerate processing and reduce power requirements. The Cortex-M4 core incorporates dsp and fpu functions that provide the power required for advanced computation. Algorithms for operating on chip flash memory have been redesigned for greater speed and lower power consumption.
