S32K is a scalable family of AEC-Q100 qualified 32-bit Arm® Cortex®-M4F and Cortex-M0+ based MCUs targeted for general purpose automo ti ve and high-reliability industrial applica TI ons.
The S32K1xx product series further extends the highly scalable portfolio of Arm®Cortex®-M0+/M4F MCUs in the automo TI ve industry. It builds on the legacy of the KEA series, while introducing higher memory op TI ons alongside a richer peripheral set extending capability into a variety of automo TI ve 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 ha rs h environments, and are optimized for cost-sensitive applications offering low pi n-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.
