NXP K32 L3 MCU Family
The K32 L3 MCU series is a family of dual-core, highly secure and energy-efficient MCUs ideal for applications in building automation, industrial and smart home.
The K32 L3 MCU family represents the third generation of Kinetis. It delivers significant improvements in power optimization and security advancements to address a wide range of industrial and IoT applications. Low-leakage, power-optimized peripherals, a DC-DC converter, and security features like authenticated boot, secure update and tamper detection pins round out
the K32 L3 MCU family.
Based on a high-performance Arm® Cortex®-M4 processor and a low-power Cortex-M0+ processor (optional), the K32 L3 MCU is ideal for applications that require a host MCU and a low-power MCU. With up to 1.25 MB flash and up to 384 kB SRAM, the K32 L3 MCU family offers ample memory resources to address different applications tasks in a small form factor, low power, and highly secure design.
