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.
