High performance automotive MCUs

09 April 2014

Freescale introduced high performance MCUs for automotive instrument clusters, that enable premium graphics.

High-end automotive instrument clusters typically incorporate multiple external components, including a main processor, graphics unit, external SRAM, and dedicated circuitry to manage heads-up display warping and other sophisticated functionality. The cost and complexity of integrating these multiple parts previously restricted this functionality to the premium car segment.

To drive heads-up display and other advanced graphics capabilities beyond the high-end and into the mid- and economy tier automotive segments, Freescale Semiconductor has introduced a triple-core, single-chip solution featuring more than 1.7x higher performance than any currently available automotive instrument cluster MCU. This high performance solution helps eliminate the need for costly additional processors and memory chips.

In addition, the triple-core MAC57D5xx helps enhance safety by separating key instrument cluster hardware and software via concurrent operation of separate operating systems on each of the devices’ three cores. Independent operation of an AutoSAR OS on the ARM Cortex-M4 core, and a graphics OS on the ARM Cortex-A5 core allows for enhanced safety in next-generation instrument cluster designs.

Simplified Development Environment
Premium cluster graphic design traditionally requires resource-intensive software development and a complex tool chain. Freescale provides a more streamlined approach, leveraging proprietary IP and optimised code for more efficient use of resources and faster time-to-market.
