S32K is a scalable family of AEC-Q100 qualified 32-bit Arm? Cortex?-M4F and Cortex-M0+ based MCUs targeted for general purpose automotive and high-reliability industrial applications.

The S32K1xx product series further extends the highly scalable portfolio of Arm?Cortex?-M0+/M4F MCUs in the automotive industry. It builds on the legacy of the KEA series, while introducing higher memory options alongside a richer peripheral set extending capability into a variety of automotive applications. With a 2.70–5.5 V supply and focus on automotive environment robustness, the S32K product series devices are well suited to a wide range of applications in electrically harsh environments, and are optimized for cost-sensitive applications offering low pin-count options.

The S32K product series offers a broad range of memory, peripherals, and package options. It sharescommon peripherals and pin counts, allowing developers to migrate easily within anMCU family or among the MCU families to take advantage of more memory or feature integration. This scalability allows developers to use the S32K product series as the standard for their end product platforms, maximizing hardware and software reuse and reducing time to market.
