2. SOFTWARE SUPPORT
2.1 Software Requirements
Before starting up SE5118A Touch Key GUI software, it is required that the PC be installed with the EzISP
USB driver and related files (for example Microsoft Framework and C++ library). Users can unzip file
EzISP_V3.3.3.zip and use the setup file for installation. But this installation needs Windows login users with
administrator privileges.
Figure 2-1: Photo of EzISP Board
Windows Software Requirements:
EzISP tool supports Win XP, Vista, Windows 7, Windows 8, Windows 10, and Windows 11. It is required
that the Windows-based PC be installed with Microsoft .NET Framework 3.5, Microsoft .NET Framework
4.8, Microsoft Visual C++ 2008, and Silicon Labs’ USB driver version 6.7.2.0. After running EzISP setup
version 3.3.8 or a later version, Windows will ask the user to install Microsoft .Net Framework or Microsoft
Visual C++ 2008 if this PC was not installed with the redistributable packages. Users can follow the pop-
up instructions to finish the installation.
Users might need up to seven steps to finish the EzISP installation and configuration after installation for
normal operation.
Step 1: For customers who have installed EzISP setup version earlier than 3.3.8 with Silicon Labs’ USB
driver version 3.2.0.0, USB driver version 3.2.0.0 needs to be uninstalled as the four steps in the
below figure before installing the new EzISP setup version 3.3.8.

Lumissil Microsystems – www.lumissil.com 7
Rev. C, 06/28/2023
IS31SE5118A EvB User’s Manual
Step 2: Install EzISP setup program. After the installation is done and EzISP is run, users might get
below pop-up message and please update with the newer BIOS as Step 3 ~ Step 7.
Users can check whether the Silicon Labs’ USB driver version 6.7.2.0 is correctly installed
or not as the two steps in the below figure.
Step 3: Go to “Tool(T)”–> “Update EzISP BIOS(U)”

3.1 Before Use
IS31SE5118A EvB board should have standard code/firmware inside, but users can follow below step 1 to
step 3 to program firmware to start evaluation of this board in case there is no standard code firmware
inside.
Step 1. Click the Program Device FW from the File drop-down menu.
Step 2. Click Select to open the firmware file then click Program. If Configuration File is not selected,
then the default settings will be programmed. Users can click “Export Configuration to File” to
save the current configuration and choose the preferred configuration file before performing
“Program Device FW”.
Step 3. Close the “Update Code”window and click the “Connect” button if the “Connect” status box is
not green. (If IS31SE5118A EvB kit is not connected to the PC before this software is run,
“Connect” status box will be red after running this software.)

3.2 Connect Status
Before running Touch Key GUI tool, please make sure SW2 switch of the IS31SE5118A EvB is all OFF.
Users can refer to Section 1.1 Evaluation Board to find SW2.
The I2C slave address is fixed at 0x78, as shown in Figure 3-5: GUI Connect Status Shows Disconnect
with IS31SE5118A EvB connected to PC via EzISP board. If the user finds the “Device” status in red,
please try to re-connect the devices connection with PC USB port, then close and run Touch Key GUI tool
again. If the “Device” status still shows red, it might be because the device’s boot code is not correctly
burned. If the “Connect” status is in yellow color after trying to re-connect devices connection with PC
USB port and running Touch Key GUI tool again, it might be caused by standard code not being correctly
burned.

3.3 Export/Import Configuration File
As shown in Figure 3-7 below, Export Configuration to File is used to export the configuration of
IS31SE5118A and save in a file. By exporting the configuration, we can save the parameters settings in the
GUI to a file (The default file name is an excel file “register values” and users can define file name for
version control). It also simultaneously creates a BIN file in the same folder and the file can be used for
manufacture.
Import Configuration from File is used to import the configuration setting from the preferred IS31SE5118A
GUI settings file into the device. Click Apply to apply the parameters to the device.
Figure 3-7: GUI Import/Export Options
3.4 Update Configuration to Flash
As shown in Figure 3-8 below, users can write the parameters settings in the GUI into the flash of the
IS31SE5118A chip. After clicking the Update Configuration to Flash from the File drop-down menu,
writing configuration settings to the flash can be completed in about 4 seconds.
The embedded Flash Memory has the capability to hold the saved data even if the power is off. When
IS31SE5118A is powered on again, the parameters previously written to the flash will become the default
values.
