The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the PCA9958HN-ARD evaluation board.

    3.1 Configure Hardware

    PCA9958HN-ARD evaluation board is connected to the LPC55S69-EVK MCU board using four connectors (J5/J6/J35/J36 on PCA9958HN-ARD board and P16/P17/P19/P18 on LPC55S69-EVKboard) for SPI-bus and power supply.

    The LPC55S69-EVKMCU board communicates with PCA9958HN demo GUI through PC USB port and uses SPI to communicate to PCA9958HN.
