Board feature Target MCU features used Description
MCXN947 MCU
(target MCU)
The MCXN947 MCU is based on dual high-performance
Arm Cortex-M33 cores running up to 150 MHz, with 2 MB of
Flash with configurable full ECC RAM, a DSP coprocessor
and an integrated proprietary neural processing unit (NPU).
For details, see the MCX Nx4x Reference Manual.
