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 will guide you through learning about how to set up the KITFS85AEEVM board.

To generate Device OTP programming and emulation you will need the following:

Refer to UM11193: KITFS85AEEVM Evaluation Board - User Guide for full evaluation board functionality.

2. Plug It In

The KITFS85AEEVM provides flexibility to play with all the features of the device and make measurements on the main part of the application. The KL25Z MCU installed on the board, combined with the FlexGUI software allows access to the registers in reading and writing mode. All regulators are accessible through connectors. Nonuser signals, like DC/ DC switcher node, are mapped on test points. Digital signals (SPI, I²C, RSTb, etc.) are accessible through connectors. Wake1 pin has a switch to control (Ignition) them. A VBAT switch is available to power On or Off the device.

The main purpose of this kit is the evaluation of the device in the truck environment which need a nominal voltage of 24 V and to sustain up to 60 V at Vbat. The KITFS85AEEVM is also able to work in emulation mode and to burn the device when needed. Devices can be programmed three times.

2.2 Board Description

KITFS85AEEVM provides easy customer development of the FS84/FS85 family devices. It's targeting 24 V Truck applications. This KIT can be connected to the FlexGUI software which allows the customer to modify the registers, develop an OTP Configuration (one Time Programming) configuration and burn it when ready. The FS85 on the board has not been programmed, offering the customer the flexibility to configure the OTP for his application needs. The OTP can be burned 3 times, which gives good flexibility. The board contain a superset device (MC33FS8530AE0S), allowing tests on all the FS84/FS85 derivatives.

3. Configure Hardware

This section summarizes the overall setup. Detail description is provided in the user guide.

Suggested equipment’s needed for test:

  • 8.0 V to 40 V power supply
  • Computer
  • Mini USB type A Cable

3.1 Configuration Image

3.2 Device Considerations

It is recommended to learn about OTP before operating with the device. The device has a high level of flexibility due to parameter configuration available in the OTP. This impacts the functionality of the device. It is key to understand how OTP parameters can be programmed, the interaction with mirror registers and the FS85 SoC. The OTP related operations can be performed either in Emulation mode, where the product uses a given configuration as long as power supply is not switched Off or from OTP fuse content that is valid even after a power down/power up sequence.

3.3 Setting up the Board

To configure the hardware and workstation as illustrated in Figure 18, complete the following procedure:

  1. Install jumpers for the configuration
  2. Table Jumper configuration

    Jumper Configuration
    J24 connect 1-2 (connect 5.0 V on DBG pin from the USB)
  3. Configure switches for the configuration
  4. Table Switch configuration

    Switch Configuration
    SW1 middle position (VBAT off)
    SW2 open (WAKE1)
    SW3 open (OTP programming off)
  5. Connect the Windows PC USB port to the KITFS85AEEVM development board using the provided USB 2.0 cable
    • Set the DC power supply to 12 V and current limit to 1.0 A. With the power turned off, attach the DC power supply positive and negative output to KITFS85AEEVM VBAT Phoenix connector J1
  6. Turn on the power supply
  7. Close SW2

Install Software

4.1 Preparing Graphical User Interface Operating Environment

Download and run latest FlexGUI SW for the KITFS85AEEVM.

4.2 Installing FlexGUI Software Package

FlexGUI is based on Java JRE. Install Java JRE, and then unzip the FlexGUI software package on your computer.

The FlexGUI software does not require any installation. Unzip the folder contents and launch the .bat file.

  1. Download Java JRE (Java SE Runtime Environment) available at Java SE Development Kit 8u411 (8u162 or newer)
  2. Accept the license agreement
  3. Select either x64 or x86 installer for your current platform (typically Windows x64 or Windows x86)
  4. Initiate file download and wait for completion
  5. Run the installer
  6. Restart the computer after successful download
  7. On Windows 10, it is not necessary to install virtual com port as it uses generic COM port driver
  8. On Windows 7, a virtual COM port installation is required, please refer to the user manual

The image below shows the mode selection. At first launch, the FlexGUI starts in User mode. The user can then decide to switch to Test mode using the Switch mode drop-down list.
