NXP – S32K14xW General Purpose Microcontrollers

High-temperature AEC-Q100 Grade 0 with CAN FD and Safety

The S32K1 family of 32-bit AEC-Q100 qualified MCUs combines a scalable family of Arm® Cortex®-M based microcontrollers built on long-lasting features with a comprehensive suite of production-grade tools supporting up to ASIL B automotive and industrial applications.

S32K1 MCUs feature ultra-low-power operating modes, a cryptographic security engine with NXP firmware and an automotive-grade Software Development Kit (SDK) with low-level drivers and the FreeRTOS™ OS. The S32K1 MCUs are available in QFN, LQFP and MAPBGA packages.

The S32K14xW microcontrollers for high-temperature (AEC-Q100 Grade 0 qualified: -40° C to +150° C Ta) are the latest addition to the S32K1 MCU family.

Based on the 32-bit Arm® Cortex®-M4F core, the S32K14xW MCUs (available on 48LQFP and 64LQFP package options) offer CAN FD and LIN, together with CSEc hardware security capabilities and ISO 26262 up to ASIL B functional safety compliance, guaranteeing a minimum of 15 years of assured supply.

S32K14xW Grade 0 MCUs are highly (pin-to-pin) hardware- and software- compatible with S32K1 Grade 1 devices.
