1. Out of the Box

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 guides you through the process of setting up and using the KITFS27EVM programming board.

1.1 Kit Contents and Packing List

The kit contents include:

  • Assembled and tested programming board and preprogrammed FRDM-KL25Z board in an antistatic bag
  • 3.0 ft USB-STD A to USB-B-mini cable
  • Six connectors, two-position terminal block plug, straight 3.81 mm
  • Two connectors, three-position terminal block plug, straight 3.81 mm
  • Jumpers mounted on board
  • Quick Start Guide

1.2 Additional Hardware

In addition to the kit contents, the following hardware is necessary when working with this board:

  • Power supply with a range of 8.0 V to 40 V and a current limit set initially to 1.0 A

1.3 Minimum System Requirements

This programming board requires a Windows PC workstation. Meeting this minimum specification ensures optimal performance when working with this evaluation board:

  • USB-enabled computer with Windows 7, 10 or 11

1.4 Software

Installing software is necessary to work with this evaluation board. All listed software is available on the NXP GUI for Automotive PMIC Families information page, or on our Secure Files portal if the device is not in production.
