NXP MCX N Series Advanced Microcontrollers (MCUs)
Arm® Cortex®-A55, ML Acceleration, Power Efficient MPU, Powers a New Era of Secure Edge Intelligence
The NXP MCX N Series of general-purpose MCUs feature dual Arm® Cortex®-M33 cores operating up to 150 MHz. This advanced series introduces the new instantiation of the NXP designed Neural Processing Unit (NPU). The integrated NPU delivers up to 30x faster machine learning (ML) throughput compared to a CPU core alone enabling it to spend less time awake and reducing overall power consumption. The low power cache enhances system performance and the dual bank Flash and full ECC RAM support system safety providing an extra layer of protection and assurance.
The EdgeLock® secure subsystem offers a secured boot and crypto accelerators to meet demanding requirements for over-the-air transactions. The on-the-fly encrypt and decrypt for external serial Flash/PSRAM is connected via the FlexSPI to ensure code and externally stored data is protected.
MCX N Advanced series designed for secure, intelligent edge applications. The N series includes the newly announced MCX N94x and MCX N54x MCU families featuring a highly efficient multicore architecture, an integrated EdgeLock® secure subsystem and a dedicated, on-chip neural processing unit (NPU) for real-time inference.

MCX N94x and N54x MCUs
With Dual Core Arm® Cortex®-M33, EdgeLock® Secure Subsystem and Neural Processing Unit
The MCX N94x and MCX N54x by NXP are based on dual high-performance Arm® Cortex®-M33 cores running up to 150 MHz, with 2MB of Flash with optional full ECC RAM, a DSP co-processor and an integrated proprietary Neural Processing Unit (NPU). The integrated NPU delivers up to 30x faster machine learning (ML) throughput compared to a CPU core alone enabling it to spend less time awake and reducing overall power consumption.
The multicore design delivers improved system performance and reduced power consumption by enabling smart, efficient distribution of workloads to the analog and digital peripherals. The devices are supported by the widely adopted MCUXpresso suite of software and tools to optimize, ease and help accelerate embedded system development.
The MCX N94x family is geared toward industrial applications with a wider set of analog and motor control peripherals, while the MCX N54x family targets consumer and IoT applications with peripherals ranging from high-speed USB with a PHY to secure digital (SD) and smart card interfaces.
