TUSS44x0 EVM for Ultrasonic Sensors User's Guide
The TUSS44x0 Evaluation Module (EVM) lets users evaluate the functionality of Texas Instrument's
TUSS4440 and TUSS4470 ultrasonic sensor-signal conditioner and driver integrated circuits. The
TUSS4440 and TUSS4470 devices are highly integrated transducer drive analog front-end devices for
industrial ultrasonic applications. This user’s guide describes both the hardware platform containing a
sample TUSS4440 (BOOSTXL-TUSS4440) or TUSS4470 (BOOSTXL-TUSS4470) device, and the
graphical user interface (GUI) software used to configure and operate the device. This EVM can be used
to display the ultrasonic echo envelope and time-of-flight measurement results of the transducer when
used with the GUI.

TUSS44x0 EVM for Ultrasonic Sensors User's Guide
1 Introduction
The BOOSTXL-TUSS44x0 EVM is a fully assembled evaluation module (EVM) designed for the combined
evaluation of the TUSS44x0 ultrasonic-sensor signal conditioner IC and ultrasonic transducer.
The accompanying MSP430F5529 LaunchPad™ Development Kit (MSP-EXP430F5529LP) is used as the
USB-to-PC GUI communication bridge as an example on how to implement a master MCU to
communicate with and control the TUSS44x0 through SPI and GPIO interfaces.
NOTE: The BOOSTXL-TUSS44x0 requires an external master controller to evaluate the TUSS44x0.
The TUSS44x0 is exclusively a slave device.
The MSP-EXP430F5529LP is controlled by commands received from the BOOSTXL-TUSS44x0 EVM
GUI, and returns data to the GUI for display and further analysis. If the MSP-EXP430F5529LP is not used,
the BoosterPack™ Plug-in Module format of the TUSS44x0 EVM allows alternative external master
communication to the TUSS44x0.
The BOOSTXL-TUSS44x0 incorporates all required circuitry and components for operation with the
following features:
• TUSS44x0 ultrasonic sensor signal conditioner IC
• Multiple test points for various analog and digital signals
• Ultrasonic sensing transducer for mono-static time-of-flight measurements
Figure 1 shows the TUSS44x0 EVM architecture, identifying the key components and blocks previously
listed.

TUSS44x0 EVM for Ultrasonic Sensors User's Guide
To properly evaluate the TUSS44x0 EVM solution, connect and assemble the two boards as described in
these steps:
1. Stack the BOOSTXL-TUSS44x0 board on top of the MSP-EXP430F5529LP. Pin 1 of the MSP-
EXP430F5529LP must align with pin 1 of the BOOSTXL-TUSS44x0 LaunchPad-BoosterPack
connector (J1).
2. Position the power mode jumper for the intended use-case (see Figure 3).
3. Connect the transducer to the terminal block at J2.
4. Set the CFLT shunt(s) at J1 and CINN shunts(s) at J4 to most closely equal (or rounded up to) the
calculated capacitance values based on the transducer frequency.
5. Connect the micro-USB cable to a PC (see Section 2.1.2.2).
6. If using an external power supply, turn on the supply (see Section 2.1.2.2).
Figure 3 shows the assembled solution for the BOOSTXL-TUSS44x0 board configuration.
Figure 3. EVM Boards - Assembled
WARNING
This EVM contains components that are sensitive to electrostatic
discharge (ESD). Use proper laboratory techniques and equipment
to minimize the chance of an ESD or electrical overstress (EOS)
event.
2.1.2.2 Power Mode Jumper Settings
The BOOSTXL-TUSS44x0 EVM has an alternative power mode selector jumper block (J6). Depending on
the use-case, the assembled EVM can be powered from a variety of single or multiple power sources.
Table 1 lists each power mode with the jumper position of the power mode selector block.

The BOOSTXL-TUSS44x0 driver voltage and

two independent external sources: J6 Pin 6 or
J5 (MAIN) and J6 Pin 2 (VDD).
This options requires all jumpers at J8 to be
removed to disable and disconnect the 3.3-V
LDO input and output.
MAIN is rated for a voltage range of 5 V to 36 V, and VDD is rated for a voltage of 3.3 V when paired with
the MSP-EXP430F5529LP master. VDD can be increased to 5.0 V if paired with a different microcontroller
master.
The LaunchPad MCU is known to create noise at the TUSS44x0 AFE. If the noise becomes too large in
amplitude, especially for high-pass filter mode measurements, then TI recommends to make the
LaunchPad ground and BoosterPack ground common at the external power supply (if applicable) by
removing the shunt at J6 Pin 3-4. GLP is an abbreviation for Ground of LaunchPad. It can only be made
common to the BoosterPack ground through jumper at J6 Pin 3-4. This shunt is required for the USB Only
power mode of evaluation.

The BOOST-TUSS44x0 driver voltage
and voltage regulator input supplies
come from two independent external
sources: J6 Pin 4 (MAIN) and J6 Pin 2
(VDD).
TI recommends full evaluation and
development of the TUSS44x0 be
performed in this mode for best results.
MAIN is rated for a voltage range of 5 V to 36 V, and VDD is rated for a voltage of 3.3 V when paired with
the MSP-EXP430F5529LP master. VDD can be increased to 5.0 V if paired with a different microcontroller
master.
2.3 Installing the Graphical User Interface Software
Before the TUSS44x0 device can be evaluated, the GUI software must be available on a host computer.
Run the GUI installer and save the executable (.exe) file in a convenient location (such as the computer
Desktop or the C:\Program Files (x86)\Texas Instruments\ folder). Double-click the executable file or
desktop shortcut to run the application. To download the TUSS44x0 EVM GUI, go to
www.ti.com/product/TUSS44x0-EVM
2.4 Power-On the EVM
When the EVM is fully assembled and the correct power-mode jumper setting is set, the EVM is ready for
power and communication with the GUI.
The complete EVM has successfully powered when the green LED (LED2) of the MSPEXP430F5529LP
illuminates, and all available green LEDs on the BoosterPack illuminate.

3 Software
3.1 Installation
Download and install the GUI from www.ti.com. Navigate to the default installation path of the executable
file by clicking on the Windows Start button. Click on All Programs and then navigate to the Texas
Instruments folder to find the TUSS Generation III EVM GUI application. Run the latest version of the
TUSS Generation III EVM GUI-x.x.x.x.exe file. If the user must move the .exe file from the original install
location, the Microsoft.VisualBasic.PowerPacks.Vs.dll files must be moved with the .exe to the same
directory, or the GUI will fail to load.
3.2 Flash Program MSP-EXP430F5529LP
If the MSP-EXP430F5529LP has not been flash programmed with the required TUSS44x0 EVM batch
(.bat) firmware, the GUI automatically prompts the user to do this at start-up, or after the MSP-
EXP430F5529LP is plugged in to the USB port.
Figure 6. Automatic Prompt to Flash Program MSP-EXP430F5529LP
The GUI installs the tuss44x0-firmware.bat file to the My Documents folder under the Texas Instruments >
TUSS Generation III > TUSS44x0 > UNIFLASH folder. The GUI runs through the command prompt to
flash program the MSP-EXP430F5529LP. The MSP-EXP430F5529LP can be flash programmed manually
from the GUI under the File menu by selecting Flash Program and then MSP-EXP430F5529LP. The file
named tuss44x0-firmware.bat in the default installation will be selected in the background and run.
