MCX N Series Microcontrollers

MCX N series of highly integrated Arm Cortex-M33 microcontrollers are designed for high performance and low power consumption. MCX N includes intelligent peripherals and on-chip accelerators providing multitasking capabilities and performance efficiency. Select MCX N families include NXP's eIQ® Neutron neural processing unit (NPU) for machine learning applications. The low-power cache enhances system performance, while the dual-bank flash and full ECC RAM support system safety and offer an extra layer of protection and advanced security. These secure MCUs include our EdgeLock® Secure Enclave, Core Profile offering a secure-by-design approach, secure boot with an immutable root-of-trust and hardware-accelerated cryptography.

Speed up development time for general-purpose Arm® Cortex®-M-based products like the MCX N series with MCUXpresso Developer Experience.
