1. Out of the Box

The KITPF9455FRDME 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 KITPF9455FRDME board.

1.1 Kit Contents and Packing List

The kit's contents include:

  • Assembled and tested KITPF9455FRDME evaluation board with preprogrammed KL25Z microcontroller (MCU) in an antistatic bag
  • Quick Start Guide
  • 3.0 ft USB-STD A to USB-C-micro cable
  • Six Phoenix connectors, two positions, straight, 10 mm
  • Jumpers mounted on board

1.2 Additional Hardware

In addition to the kit's 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) device

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 GUI.

2. Get Software

This section covers the board components and features.

2.1 Board Features

The KITPF9455FRDME evaluation board includes the following features:

  • Phoenix 10 mm male connector or jack connector for power supply input
  • Phoenix 10 mm male connectors for PMIC switcher outputs
  • Header connectors for input/output (I/O) configuration
  • Selectable power input for programming
  • Access pin connectors for monitoring inputs and outputs
  • Red and green 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 KITPF9455FRDME 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.

3. Plug It In

3.1 Plug It In

Follow the steps below to set up the KITPF9455FRDME board:

  1. Verify that the jumpers and switches are configured in their default positions
  2. Connect the power supply to VIN-J47 (the 10 mm Phoenix connector)
  3. Connect the USB cable between the board and the PC

To launch the PF9455 NXP Graphical User Interface (GUI):

  1. Click the Windows icon
  2. Locate NXPGUI in the Windows All apps bar
  3. Click the NXPGUI icon to launch the GUI

4. Configure the Board

4.1 Configure the Board

This section will walk you through the KITPF9455FRDME evaluation board configuration. You will get an explanation of the features associated with each jumper and switch details on enabling features through hardware configuration and advice on the LED signaling and test points available on the board.

The default debug configuration enables the board to be fully controlled by the KL25Z MCU (via I2C) and the GUI. Figure 2 below shows the default jumper and switch configuration for PF9455.
