1. Out of the Box

The KITPF9455FRDMPGM board kit allows you to evaluate, design, implement and validate the PF9455 power management-integrated circuit (PMIC) for high-performance applications.

This getting started guide will walk you through the process of setting up and using the KITPF9455FRDMPGM board.

1.1 Kit Contents and Packing List

The kit contents include:

  • Assembled and tested KITPF9455FRDMPGM programming board with preprogrammed KL25Z microcontroller (MCU) in an antistatic bag
  • Quick Start Guide
  • 3.0 ft USB-STD-A to USB Micro-cable
  • Jumpers mounted on the board

1.2 Additional Hardware

In addition to the kit contents, the following hardware provides further support when using this board.

  • Power supply capable of providing 5 V

1.3 Minimum System Requirements

You will need a Windows PC workstation to evaluate the board. For best results, please use the following equipment:

  • USB-enabled computer with Windows 7 or Windows 10
  • FTDI USB serial port driver for the FT230X basic universal asynchronous receiver-transmitter (UART)

1.4 Software

Before working with the board, you will need to install software. You can find the software at the PF9455 evaluation board's page or from the NXP PMIC Graphical User Interface (GUI).

2.1 Board Features

The KITPF9455FRDMPGM evaluation board includes the following features:

  • Header connectors for input/output (I/O) configuration
  • Selectable power input for programming
  • Access pin connectors for accessing inputs and outputs
  • Red and green light-emitting diodes (LEDs) to indicate signal or regulator status
  • Blue LED to indicate that the one-time programmable (OTP) 8 V burning voltage is set
  • Advanced system monitoring via the KL25Z MCU
  • Embedded USB-to-inter-integrated circuit (I²C) protocol for connecting to the software GUI through the KL25Z MCU

2.2 Board Description

The KITPF9455FRDMPGM evaluation board integrates a KL25Z MCU to support communication between the board and the PC-based GUI to control and monitor of the PF9455 device.
