Overview

The FS32K146HFT0VLLR is an automotive-grade 32-bit microcontroller from NXP S32K1 series, powered by an Arm Cortex-M4F core with a Floating Point Unit (FPU). Operating at up to 112MHz, it features 1024KB of Flash and 128KB of RAM, specifically designed for ASIL-B functional safety applications and vehicle networking.

Why Choose This Part

This MCU provides a seamless migration path within the S32K family, offering hardware-based security and ASIL-B compliance for safety-critical systems. It operates across a wide 2.7V to 5.5V supply range and features low-power modes down to 207uA in standby, making it suitable for always-on vehicle functions.

Applications

Body Control Modules
Manages interior lighting, wipers, and window motors using its extensive PWM channels and automotive-grade timers.
Automotive Gateways
Utilizes three CAN interfaces and LIN support to route data between different vehicle sub-networks.
Electric Water Pumps
Leverages the Cortex-M4F DSP instructions and 5.5V operating range for efficient brushless DC motor control in thermal management systems.
