MCX N947 & MCX N236: Scalable MCUs for Intelligent Edge Design

NXP’s MCX N Series microcontrollers—MCX N947 and MCX N236—offer a unified silicon architecture designed to scale across performance and power profiles for edge applications.

• MCX N947 integrates dual Arm® Cortex®-M33 cores with TrustZone® and a dedicated Neural Processing Unit (NPU), enabling efficient execution of ML workloads at the edge. It supports high-speed interfaces like Ethernet, CAN-FD, and USB, making it ideal for motor control, industrial automation, and AI-enabled sensing.

• MCX N236 is optimized for ultra-low-power operation with a single Cortex®-M33 core and integrated analog and digital peripherals. It includes built-in sensor interfaces and is well-suited for battery-powered IoT devices, smart consumer electronics, and environmental monitoring.
