NXP Semiconductors MCX N Series Microcontrollers

NXP Semiconductors MCX N Series microcontrollers combine high-performance processing and low-power operation with intelligent peripherals, scalable memory, advanced analog integration, on-chip acceleration, and hardware-based security. Dual-core and single-core options address Edge AI sensing, smart metering, connected control, cost-optimized integration, and other industrial, smart home, and general embedded requirements.

The NXP MCX N portfolio includes selected devices, such as the MCX N94/N54 and MCX N55T, with an integrated eIQ^® Neutron NPU for accelerating machine-learning workloads. PowerQuad and SmartDMA help reduce processing demands by offloading signal-processing and peripheral tasks. The MCX N55T also adds post-quantum cryptography-enabled security, while the MCUXpresso Developer Experience and scalable FRDM development platforms support development across the portfolio.
