The MAC57D5xx MCU family is a multi-core architecture solution for mid-range instrument cluster and industrial applications. This MCU is based on the ARM® Cortex®-M processor for real time and an ARM® Cortex®-A processors for applications and human machine interfaces that offer leading edge performance & scalability.

The MAC57D5xx MCU supports up to 2 WVGA resolution displays, one with in line head-up display hardware warping. The graphics content is generated using a powerful Vivante 2D GPU and the 2D animation and composition engine, to reduce memory footprint for content creation, integrated stepper motor drivers and a powerful I/O processor.

The MAC57D5xx MCU integrates NXP®’s latest SHE-compliant CSE2 engine and delivers support ISO26262 ASIL-B functional safety compliance.
