About this document
Scope and purpose
This user manual explains the purpose and use of the 6EDL_SPI_LINK configuration adapter bridge (or
“dongle”), which provides an interface from a PC USB output to a target board containing a 6EDL71x1 series
smart gate driver IC. This interface is used for reading and writing the configuration parameters via a PC-based
software application. A description of the 6EDL_SPI_LINK functionality, circuitry and firmware is provided with
instructions for connection and use.
Intended audience
This document is intended for design engineers, applications engineers, and technicians who use the 6EDL71x1
series gate driver.

Introduction
1Introduction
1.1 6EDL_SPI_LINK adapter
6EDL_SPI_LINK is a configuration interface or “dongle” for use with the 6EDL71x1 family of smart gate driver
ICs. It is connected to the USB (1.0 to 2.0) interface of a PC with a standard Micro-B USB to male A cable (1 meter
or 3 ft) supplied with the kit. It is connected via the 2x4 pin, 0.1”/2.54 mm spaced vertical header to a ribbon
cable also supplied in the kit, which is connected to the target board containing the 6EDL71x1 device.
6EDL_SPI_LINK enables read and write operations to the registers that contain the configuration parameters of
the 6EDL71x1, which include; the PWM switching pattern, gate drive configuration, onboard power supplies,
and protection functions. This adapter works with a PC-based application called the MOTIX™BPA Motor
Control Workbench, which is a Windows-based graphical user interface (GUI) tool available to download from
Infineon’s website.
The configuration can be loaded into RAM during product development and optimization or into permanent
memory using the one-time programmable (OTP) mode.

Attention: The J-Link programming port located on the side of the board is used only once during
factory installation of the J-Link firmware. Never connect any circuitry to this port.
All communication between an external microcontroller and the 6EDL71x1 target device happens through an
integrated serial peripheral interface (SPI). In this case, the external MCU is the XMC1402 device located in
6EDL_SPI_LINK, which acts as the SPI master. The SPI interface reads and writes to configuration registers of
6EDL71x1, which acts as the slave. Settings can be written to the volatile RAM or permanent OTP memory. The
SPI module is based on a 4-pin configuration, which includes the following logic signals:

Functional description
The XMC4200 MCU (IC101) contains the factory-installed J-Link firmware, which provides an interface between
the USB data and the master MCU interface as shown in Figure 6. The master MCU interface is used to
download the 6EDL_SPI_LINK firmware to the XMC1402 (IC1) from the PC via the DAVE™IDE or Infineon XMC™
Flasher. This firmware is also factory installed but can be updated by the user if necessary.
The XMC1402 MCU can communicate with the MOTIX™BPA Motor Control Workbench software through the
master MCU interface and with the target 6EDL71x1 through the target IC (SPI) interface also shown in Figure 6.
Functional isolation is also included between the 6EDL_SPI_LINK target IC, ensuring that the PC is electrically
isolated from the board containing the target IC. This provides safety and avoids the possibility of damaging
the PC should any fault occur on the board containing the 6EDL71x1.

4. Connect the 6EDL_SPI_LINK adapter to the PC using the USB cable. Note that the green debugger LED
(LED101) glows (pulsations may be observed, which is normal). If LED101 does not glow, it indicates that the
adapter or USB cable is faulty.
5. Connect the 6EDL_SPI_LINK to the target board and power on this board.
Figure 14 Verify USB connection and 6EDL_SPI_LINK basic functionality
Note: 6EDL_SPI_LINK may be warm to touch around the USB connector. This is normal and does not
indicate any fault.
6. On MOTIX™BPA Motor Control Workbench, click New Project to create a new project using the 6EDL71x1
configurator (see Figure 15).
Note: Older versions of the application support only the 6EDL7141; however, additional devices are
supported in later versions.

Instructions
The “Configurator” options are used for direct communication with a specific target device. This differs from
other EVAL or REF board-specific project options available in the menu, which communicate with an XMC™
microcontroller located on the board. Infineon EVAL and REF board MCUs contain firmware that allows
them to communicate directly with a 6EDL71x1 device via an onboard or external debugger for
configuration and monitoring. 6EDL_SPI_LINK is generally not used with such boards. Instead, it is designed
for use with system boards that may contain any MCU but where the MCU does not configure the 6EDL71x1
device.
Attention: 6EDL_SPI_LINK can be used to write to either the RAM or OTP memory in the target 6EDL71x1
device. Do not use the OTP options until all of the parameters are finalized!
