S32K Automotive General-Purpose Microcontrollers
NXP S32K microcontrollers, based on the Arm® Cortex®-M series core, offer scalability, high-performance and low-power consumption tailored for applications in body, zone control and electrification. S32K MCUs provide functional safety and embedded security compliant to ASIL B/D levels, adaptable to both AUTOSAR® and non-AUTOSAR applications.
S32K MCUs are supported by a minimum of 15 years of product longevity and a comprehensive, third-party software and tools ecosystem.
As a part of the S32 Automotive Processing Platform, NXP S32K MCUs aim to provide an end-to-end solution, encompassing development, implementation and sustained performance through an Automotive-grade Software Development Kit (SDK).
