Building on the successful Kinetis K Series (K22 and K24), the K32 L3 family of MCUs delivers a 50% improvement in
power optimization and security advancements to address a wide range of industrial and IoT applications. The K32 L3
MCU family is based on the power-efficient Arm® Cortex® -M4 core and offers an optional
Cortex-M0+, providing new enhancements such as low-leakage power-optimized peripherals, a DC-DC
converter, and security features like authenticated boot, secure update and tamper detection pins.
The introduction of the K32 L3 MCU family is the start of a long line of MCUs, which will further advance NXP's
security capabilities and power optimization features to lead the market in the next generation of low-leakage
applications. The K32 L3 MCU family is complemented by a comprehensive ecosystem including MCUXpresso software and
tools and a Freedom development board for easy prototyping.
