1 MCX-N5XX-EVK overview
The NXP MCX N5XX Evaluation Kit (MCX-N5XX-EVK) board is a full-featured evaluation and development
board for application prototyping and demonstration of the MCX N54X family of devices.
The MCX N54X integrates a dual Arm Cortex-M33 MCU and a neural processing unit (NPU) into a single
package. NXP supports MCX N54X with tools and software that include hardware evaluation boards, software
development IDE, example applications, and drivers.
The MCX-N5XX-EVK development board consists of the MCX N54X device with a 64-Mbit external serial flash
(provided by Winbond), FXLS8964AF accelerometer, P3T1755DP I3C temperature sensor, visible light sensor,
Ethernet PHY, SDHC circuit, Audio codec circuit, EMVSIM connector, general-purpose RGB LED, touch slider,
FS and HS USB circuits, general-purpose push buttons, and onboard MCU-Link debug probe circuit with energy
monitoring. The board is compatible with the Arduino and FRDM ecosystem shield modules and Mikroe click
boards.
The onboard MCU-Link debug probe is based on the LPC55S69 MCU. Before using the MCU-Link functionality,
ensure that it is programmed with the required firmware. For details, see Section 3.5.
The board is a standalone PCB and supports application development with the NXP SDK software package.
Note:
•The MCX N54X represents the MCXN547 and MCXN546 devices in this document.
•For simplicity, the MCU-Link debug probe is referred to as "MCU-Link" and the MCX N54X MCU is referred to
as "target MCU" in this document.
