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 the process of setting up and using the FRDMGD3160CSLEVM board.

2.2 Board Description
The FRDMGD3160CSLEVM is a half-bridge evaluation board populated with two GD3160 single channel IGBT or SiC gate drive devices. The board supports connection to an FRDM-KL25Z microcontroller for SPI communication configuration programming and monitoring. The board includes desaturation (DESAT) circuitry for short-circuit detection and implementation of GD3160 shutdown protection capabilities.
The evaluation board is designed to connect to Bosch CSL SiC module for evaluation of the GD3160 performance and capabilities.
2.3 Board Components
Overview of the FRDMGD3160CSLEVM board
The FRDMGD3160CSLEVM is a half-bridge evaluation kit populated with two GD3160 single channel gate drive devices. The kit includes the Freedom KL25Z microcontroller hardware for interfacing a PC installed with FlexGUI software. This NXP software interfaces the communication to the serial peripheral interface (SPI) registers on the GD3160 gate drive devices in either daisy chain or standalone configuration.
The KITGD316XTREVB translator board is used to translate 3.3 V signals to 5.0 V signals between the MCU and GD3160 gate drivers. The evaluation kit can be connected to a compatible insulated gate bipolar transistor (IGBT) or SiC module for half-bridge evaluations and applications development.
Kinetis KL25Z Freedom Board
The Freedom KL25Z is an ultra low-cost development platform for Kinetis L series MCU built on Arm Cortex-M0+ processor.
3.3 V to 5.0 V Translator Board
KITGD316XTREVB translator enables level shifting of signals from MCU 3.3 V to 5.0 V SPI communication.
| Jumper | Position | Function |
|---|---|---|
VCCSEL (J3) |
1-2 | selects 5.0 V for 5.0 V compatible gate drive |
| 2-3 | selects 3.3 V for 3.3 V compatible gate drive | |
PWMH_SEL (J4) |
1-2 | selects PWM high-side control from KL25Z MCU |
| 2-3 | selects PWM high-side control from fiber optic receiver inputs | |
PWML_SEL (J5) |
1-2 | selects PWM low-side control from KL25Z MCU |
| 2-3 | selects PWM low-side control from fiber optic receiver inputs |
3. Install and Configure Software Tools
Software for FRDMGD3160CSLEVM is distributed with the FlexGUI tool (available on NXP.com). Necessary firmware comes pre-installed on the FRDM-KL25Z with the kit.
Even if the user intends to test with other software or PWM, it is recommended to install this software as a backup or to help debugging.
3.1 Installing FlexGUI on Your Computer
The latest version of FlexGUI supports the GD3100 and GD3160. It is designed to run on any Windows 10 or Windows 8 based operating system. To install the software, do the following:
- Go to FlexGUI and click Download
- When the FlexGUI software page appears, click Download and select the version associated with your PC operating system
- FlexGUI wizard creates a shortcut, an NXP FlexGUI icon appears on the desktop. By default, the FlexGUI executable file is installed at
C:\flexgui-app-des-gd31xx.exe. Installing the device drivers overwrites any previous FlexGUI installation and replaces it with a current version containing the GD31xx drivers. However, configuration files (.spi) from the previous version remain intact
