1 Introduction
1.1 Context
The tool context is to enable the user to create an engineering environment that enables him to evaluate the
SX8722 chip performances.
The tool is intended to be the interface between the sensor and the PC in order to ease the handling of the
SX8722.
The tool is made of 3 parts:
1.2 Global function
The SX8722 evaluation board’s main function is to give the user the possibility to develop its application by
interfacing his sensor, choosing its power supply, finding the best configuration parameters via the GUI, etc.
Once the ideal settings found, the corresponding configuration can be optionally saved in a 256 kBits EEPROM
and the application board used in stand-alone real application environment.
2 Installation
2.1 Installing the GUI and required software
Put the SEMTECH CD ROM in your computer and if the installation does not start launch the file “setup.exe”
located at your CD ROM root directory.
The Installer will propose you to install the “SX87xx Evaluation Tools” GUI and the software needed to make it
work.
2.1.1 .NET Framework 2.0
The GUI needs the .NET Framework 2.0 to work properly. The installer proposes to install it, if the installer is
unable to detect it on your system.
2.1.2 FTDI USB drivers
The XE8000EV120 board uses a USB to UART converter from FTDI-Chip thus to the board work properly the
USB drivers must be installed.
If the USB drivers are not detected on your PC their installation will be proposed.

SX8722 application board: Holds the SX8722 and its mandatory components and reproduces the chip
pin out in a dual line SMD 1.27mm pitch.
XE8000EV120: Gives access to all pins of the application board and provides all the hardware
interfaces needed to evaluate the SX8722.
“SX87xx Evaluation Tools” Graphical User Interface (GUI): Gives the user a clear view of the registers
content and allows the using of all modes and commands described in the SX8722 datasheet.
