NXP Semiconductors has introduced the S32K5 microcontroller family, the first 16nm FinFET MCU with embedded magnetic RAM (MRAM), designed to advance zonal software-defined vehicle (SDV) architectures and extend the NXP CoreRide platform. These microcontrollers aim to help automakers consolidate electronic control units (ECUs) without sacrificing latency or efficiency.
The S32K5 family features Arm Cortex CPU cores running up to 800 MHz for high-performance applications, embedded MRAM for faster ECU programming and over-the-air updates, an integrated Ethernet switch core for seamless network design and software reuse, and an eIQ Neutron neural processing unit for power-efficient machine learning at the vehicle’s edge. It also includes a post-quantum cryptography security accelerator to protect against future cybersecurity threats and ASIL-D safety features for secure partitioning of critical applications.
These microcontrollers will support zonal and electrification architectures, offering scalable, software-defined solutions to speed up vehicle development and reduce lifecycle costs. NXP has partnered with automotive software leaders such as Elektrobit, Green Hills Software, Sonatus, and Synopsys to ensure seamless integration into existing and future vehicle systems.
The S32K5 family will begin sampling in Q3 2025, providing automakers and Tier-1 suppliers with a next-generation platform for advancing SDV architectures.
