NPI Body

NXP Semiconductors MCX N94x/N54x MCUs

MCX N94x and N54x MCUs with dual core Arm® Cortex®-M33, eIQ® Neutron NPU and EdgeLock® secure enclave core profile

MCX N Series are high-performance, low-power microcontrollers with intelligent peripherals and accelerators providing multi-tasking capabilities and performance efficiency. Select MCX N families include NXP’s eIQ® Neutron neural processing unit (NPU) for machine learning applications. 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. The first families to launch within the MCX N series are the MCXN94x family and the MCXN54x family. Details on products within those families are detailed below.
