Fastest mcus built on ARM Cortex-M range?

The company says its Kinetis X series is 'redefining the boundaries of mcu performance' by providing an optimal combination of performance, memory and integrated peripherals. According to Freescale, the series extends beyond typical mcu limits with higher performance, more memory and development support. The Kinetis X series shares the same ARM Cortex-M4 core - with dsp and floating point instructions – used for other Kinetis devices, but with an increased operating frequency up to 200MHz, the fastest of any Cortex-M class mcu. The series' internal memories include 1-4Mbyte of flash and 0.5Mbytr of sram, with multiple off chip memory options available. According to Freescale, the series is suitable for automation, point of sale, medical instrumentation, test & measurement and HMI system applications. The mcus feature several hardware acceleration techniques designed to maximise the system performance by freeing the core from memory access limitation and peripheral servicing constraints. These include large on chip instruction and data caches, 32KB of sram and a 64channel DMA controller. The series also includes a 64bit AXI bus – a first in Cortex-M class mcus. The mcus offer 1 to 4Mbyte of embedded flash memory and 0.5Mbyte of ECC enabled sram. According to Freescale, this level of memory integration is among the highest of any mcu. Geoff Lees, vice president of Freescale's Industrial and Multi-Market mcu business, said: "Our customers' processing needs are evolving at a dramatic rate as they build products that are more powerful, connected and interactive than ever before. The Kinetis X series provides a level of performance, memory and feature integration not previously seen in this class of mcus and gives our customers the design flexibility they need to stay at the forefront of their markets."
