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 KITFS85SKTEVM board.

2.1 Board features

The KITFS85KTEVM 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 read and write mode. All regulators are accessible through connectors. Nonuser signals, like DC/ DC switcher nodes 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 to burn the OTP configuration. The KITFS85KTMEVM is a hardware evaluation tool that allows OTP burning. Due to the socket, the FS84/FS85 part can be configured without the need to solder it. Devices can be programmed three times.

Note: Due to the socket, this kit is not optimized for performance measurement or current higher than 1.0 A.

2.2 KITFS85SKTEVM evaluation board features

  • VBAT power supply connectors (Jack and Phoenix)
  • VPRE output capability up to 1.0 A (socket limit)
  • VBUCK1/2 in Standalone (default) or Multiphase mode
  • VBUCK3
  • VBOOST 5.0 V or 5.74 V
  • LDO1 and LDO2, from 1.1 V to 5.0 V
  • Ignition key switch
  • FS0B external safety pin
  • Embedded USB connection for easy connection to software GUI (access to SPI/I2C bus, IOs, RSTB, FS0B, INTB, Debug, MUX_OUT, regulator)
  • LEDs that indicate signal or regulator status
  • Support OTP fuse capabilities
  • USB connection for register access, OTP emulation and programming
  • Voltage monitoring jumper setting

*Integrated FRDM-KL25Z as a communication link between the EVB and a PC

2.3 Board Descriptions

The KITFS85KTMEVM is a hardware evaluation tool that allows OTP burning. Due to the socket, the FS84/FS85 part can be configured without the need to solder it. Devices can be programmed three times. An Emulation mode is possible to test as many configurations as needed. An external LDO provides VDDI2C voltage with a choice of 1.8 V or 3.3 V (default). VDDIO is assigned by default to VDDI2C. From USB voltage, an external DC/DC generates the OTP programming voltage (8.0 V) without any need for an external power supply.

3.3 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 if the power supply is not switched Off or from OTP fuse content that is valid even after a power down/power up sequence.

Note: The board is delivered without any OTP configuration on the associated device. To fuse the OTP first time, see user guide section on "OTP programming fuse mode steps" and use the FS85_OTP_Configuration.xls spreadsheet.

Note: The board is delivered without any OTP configuration on the associated device. To fuse the OTP first time, see user guide section on "OTP programming fuse mode steps" and use the FS85_OTP_Configuration.xls spreadsheet.

3.4 Setting up the board

1. Prior to starting your work in Debug mode, you need to start with the following configuration:

  1. Plug jumper J17 1-2 (connect 5.0 V on DBG pin from the USB).
  2. Place SW1 in the middle position (VBAT Off).
  3. Open SW3 (OTP programming Off).
  4. Open SW2 (WAKE1).

2. Connect your board to the computer with the USB cable, and to the power supply (typically set to 12 V).

3. Launch FlexGUI (see Section 7.2 "Using FlexGUI").

4. To operate in Debug mode:

  1. Place SW1 in TOP direction (VBAT switched On).
  2. Close SW2 (WAKE1).

5. At this step, the device is in Debug mode, all regulators are turned Off.

The user can load the mirror registers to work in OTP emulation. See Section 7.2.3 "Script editor" of the UM11183 user guide.

6. If the mirror register is not filled, the OTP fuse configuration, if any, will be used.

7. Unplug jumper J17 1-2.

At this step, the device will start with the mirror configuration setting (either loaded in Emulation mode, or from the OTP fuse). If the mirror was not filled and the OTP fuse not burned, then the device will not start up.

If initialization phase is not closed by a first good WD_Answer, the WD will not start and regulators will stay alive. Also, if Debug mode is not exited by writing FS_STATES:[DBG_EXIT] bit to 1, the FS0b pin cannot be released.

3.5 Additional Board Support

Detailed configuration, OTP device programming modes, closing the initialization phase and images are available in the User Guide. Refer UM11183.

Install Software

4.1 Preparing graphical user interface operating environment

Download and run the Software.

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 http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html (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 Guide for more details.

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.
