Getting Started with the PF8101/PF8201 Evaluation Boards

2.1 Board Overview

The KITPF8101FRDMEVM or the KITPF8201FRDMEVM 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.

These customer evaluation boards feature the PF8101/PF8201 power management IC. The kits integrates all hardware needed to fully evaluate the PMIC. They integrate a communication bridge based on the FRDM-KL25Z freedom board to interface with the FlexGUI software interface to fully configure and control the PF8101/PF8201 PMIC.

2.3 Product Descriptions

The KITPF8101FRDMEVM / KITPF8201FRDMEVM are a hardware evaluation boards that allow the full evaluation of the PF8101/PF8201. The PF8101/PF8201 family of devices feature power management integrated circuit (PMIC) designed for high performance i.MX 8 and S32V based applications. It features seven high efficiency buck converters and four linear regulators for powering the processor, memory and miscellaneous peripherals.

Built-in one time programmable memory stores key startup configurations, drastically reducing external components typically used to set output voltage and sequence of external regulators. Regulator parameters are adjustable through high-speed I2C after start up offering flexibility for different system states.

The PF8101/PF8201 family comprises two versions of this PMIC, to address different market needs:

• PF8201 is the flagship version of this family providing a full feature PMIC with integrated functional safety mechanism to comply with the ISO 26262 standard and providing a powerful and flexible solution for ASIL B(D) automotive modules.
• PF8101 is the non-safety version of this product, providing all the power management and digital control included in PF8201, without the functional safety overhead to provide a more economic platform for non-safety systems.

3.2 Configuration Image

3.3 Device Considerations

It is recommended to learn about the device and its specifications prior to operating the boards. 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 the parameters are programmed on the device.

Note: The board is populated with a MC33PF8101A0ES or MC33PF8201A0ES.

3.4 Setting Up the Board

To configure the hardware and workstation as illustrated.

1. With the USB cable connected to the PC and the USB port in the freedom board, apply VIN to the evaluation board.
   • Provide external VIN between 2.5 to 5.5 V on J10 (VIN) and J4 (GND)
   • Short jumper J17 to provide 3V3 Vin from Freedom board (use this mode of operation for functional demonstration only, no regulation loading allowed in this mode)
   Note: Do not apply power to J10 while J17 is shorted. This could damage the onboard regulator on the FRDM-KL25Z Freedom board.
2. Press Reset on the Freedom board, to ensure that board is properly recognized.
3. Browse to the NXP_FlexGUI/bin/ folder and double-click on the flexgui-app-8xxx.jar executable to start the application.
4. The FlexGUI launcher is displayed with a list of possible configurations to load the FlexGUI. Select the appropriate option for device and silicon revision to be used. If the device revision populated on the evaluation board is not available in the list, please contact your NXP representative to obtain the latest software update suitable for your device.

3.5 Additional Board Support

Detailed configuration, Flex GUI options are detailed in the User Guide. Refer UM11213 - PF8101_PF8201 Evaluation Boards - User Guide

4.1 Preparing Graphical User Interface Operating Environment

Download and run SW for the KITPF8101FRDMEVM or the KITPF8201FRDMEVM. These evaluation boards use FlexGUI software for PF8101/PF8201 device. Prior to the installation of the FlexGUI software and performing device firmware updates (if needed), download and unzip the NXP_FlexGUI_PF8x_REV_0.7.x.zip file to any desired location.

4.2 Installing the Java JRE

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. Open the installer and follow the installation instructions
3. Following the successful installation, restart the computer

4.3 Installing FlexGUI Software Package

The FlexGUI software installation requires only extracting the zip file in a desired location.

1. If necessary, install the Java JRE and Windows 7 FlexGUI driver.
2. Download the latest FlexGUI (32-bit or 64-bit) version, NXP_FlexGUI_PF8x_REV_0.7.x.zip.
3. Extract all the files to a desired location on your PC. FlexGUI is started by running the batch file, NXP_FlexGUI_PF8x_Rev_0.7.x\NXP FlexGUI\bin\flexgui-app-pf8xxxx.bat.

The FlexGUI Rev 0.7.0 or higher, interfaces with the FRDM-KL25Z freedom board via USB-HID protocol which should be recognized automatically by the Windows OS eliminating the need for any extra hardware drivers. Refer to UM11213 Section 5.4 "Updating the PF8101/PF8201 FlexGUI firmware" for details on how to update the FRDM-KL25Z, in case the board is not loaded with the latest firmware with USB-HID support.

4.4 Updating the PF8101/PF8201 FlexGUI Firmware

The FRDM-KL25Z freedom board is used as a communication bridge to interface the FlexGUI with the PMIC and other I²C devices. The firmware is organized in three levels:

1. At first level, the SDA uses the BOOTLOADER to operate as the main path to flash the functional code of the SDA processor. The BOOTLOADER is preprogrammed on the FRDM-KL25Z freedom boards and cannot be reflashed to avoid permanent damage to the Freedom board.
2. At second level, the SDA provides a firmware loader for drag and drop update of the KL25Z MCU firmware.
3. At the third level, the KL25Z MCU provides the FlexGUI firmware in charge of converting the USB communication into MCU instructions to control digital I/Os as well as I²C communication to the PMIC. If the FRDM-KL25Z is not loaded with the correct firmware to support a future software upgrade, the firmware can be updated in few simple steps.

4.5 Flashing the FRDM-KL25Z Firmware Loader

1. Press the push button on the Freedom board and connect the USB cable into the SDA port on the Freedom board. A new BOOTLOADER device should appear on the left pane of the file explorer.

2. Drag and drop the file MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA into the BOOTLOADER drive. File should be located in the KL25Z firmware folder.

3. Disconnect and reconnect the USB cable into the SDA port (this time without pressing the push button). A new device called FRDM_KL25Z is installed on the PC.

4.6 Flashing the FlexGUI Firmware

If a new software or silicon release requires a firmware update on the FRDM-KL25Z freedom board, use the following procedure to upgrade or downgrade the firmware of the freedom board as needed. Note that this procedure is needed only to update the firmware and may be skipped if no change is needed.

1. Connect the USB cable in the SDA port (without holding the push button).

2. Locate the ".bin" FlexGUI driver to be installed, for example flexgui-fw-kl25z-usb-hidpf8x00- v0.1.1.bin, drag and drop the file into the FRDM_KL25Z driver.

3. Freedom board firmware is successfully loaded.
