Power Supplies
4.1
TSC Power
Power for the TSC2006 SNSVDD, analog, and sense driver power supply, can be supplied either from
+1.8 V or from +3.3 V, selected by setting JMP2. When the shunt is installed on JMP2 pins 1-2, power
SNSVDD come from J3.7 (+1.8VD) through an inductor to prevent digital noise from coupling into the
analog supply. When the shunt is installed on JMP2 pins 2-3, power SNSVDD come from J3.9 (+3.3VD)
through an inductor to prevent digital noise from coupling into the analog supply. Also, the user can
remove the shunt and connect an external power supply to the pin 2 of JMP2 if other than 1.8-V or 3.3-V
power is used. By default factory setting, SNSVDD is set to +3.3VD, shunt on JMP2 pins 1-2..
Power for the TSC2006 IOVDD and digital IO power supply is selected using JMP4, either 1.8V or 3.3V or
SNSVDD. When JMP4 is in the default factory condition (shunt on pins 3-4), power to the TSC is
connected to the same power supply as SNSVDD.
4.2
Stand-Alone Operation
When used as a stand-alone EVM, the analog power can be applied to TP1 (SNSVDD) and referenced to
TP4 (GND). IOVDD can be applied to TP2 (IOVDD) and referenced to TP4.
CAUTION
Verify that all power supplies are within the safe operating limits shown on the
TSC2006 data sheet before applying power to the EVM.
4.3
USB-MODEVM Interface Power
The USB-MODEVM Interface Board can be powered from several different sources:
• USB
• 6-VDC to 10-VDC AC/DC wall supply (not included)
• Laboratory power supply
When powered from the USB connection, JMP6 should have a shunt from pins 1-2 (this is the default
factory configuration). When powered from 6-VDC to 10-VDC, either through the J8 terminal block or J9
barrel jack, JMP6 should have a shunt installed on pins 2-3. If power is applied in any of these ways,
onboard regulators generate the required supply voltages and no further power supplies are necessary.
If laboratory supplies are used to provide the individual voltages required by the USB-MODEVM Interface
Board, JMP6 should have no shunt installed. Voltages then are applied to J2 (+5VA), J3 (+5VD), J4
(+1.8VD), and J5 (+3.3VD). The +1.8VD and +3.3VD can also be generated on the board by the onboard
regulators from the +5VD supply; to enable this, the SW1 switches need to be set in the ON position
(lower position, looking at the board with text reading right-side up) to enable the regulators. If +1.8VD and
+3.3VD are supplied externally, disable the onboard regulators by placing the SW1 switches in the OFF
position.
Each power-supply voltage has an LED (D1–D7) which lights when the power supplies are active.
4.4
Reference Voltage
The reference voltage can be provided on the board from SNSVDD on TSC2006EVM. An external
reference can be supplied through J1 pin 20 referenced to analog ground (J1 pin 18 on the
TSC2006EVM), or through TP3 (VREF) referenced on TP4(GND) on the TSC2006EVM. JMP1 must be
set correspondingly, as shown in Table 4.

The USB-MODEVM Interface board is intended to be used in USB mode, where control of the installed
EVM is accomplished using the onboard USB controller device. However, provision is made for driving all
the buses (I2C and/or SPI) externally. The source of these signals is controlled by SW2 on the
USB-MODEVM. For more details, see the USB-MODEVM Interface Board schematic in Section 7.2.
6.2
Quick Start
Ensure that the TSC2006EVM is installed on the USB-MODEVM Interface Board. The TSC2006EVM
should be installed in the topmost position, using J11, J12, and J13 on the USB-MODEVM, as shown in
Figure 1 .
Place the CD-ROM into your PC's CD-ROM drive. Locate the Setup program on the disk, and execute it.
The Setup program installs the TSC2006 evaluation software on your PC. Follow the instructions and
prompts given.
When the installation completes, click Finish on the TSC2006EVM installer window. You may be prompted
to restart your computer.

Kit Operation
When installation is complete, attach a USB cable from your PC to the USB-MODEVM Interface board. As
configured at the factory, the board is powered from the USB interface; so, the power indicator LEDs on
the USB-MODEVM should light. Once this occurs, launch the TSC2006 evaluation software on your PC.
The software should automatically find the TSC2006EVM, and a screen similar to the one in Figure 2
should appear.
Figure 2. Default Software GUI Screen
In order to use the touch screen features, a 4-wire resistive touch screen needs to be connected to J1 of
the TSC2006EVM, as described previously. That is: the 4 wires of the touch panel should be connected to
the pins 2 (X+), 4(X–), 6(Y+), and 8(Y–) of J1A on the TSC2006EVM board.
6.3
USB-MODEVM Interface Board
The simple diagram shown in Figure 1 shows only the basic features of the USB-MODEVM Interface
Board. The board is designed for a TAS1020B USB controller with an 8052-based core. It features two
positions for modular EVMs, or one double-wide serial modular EVM can be installed.
For use with the TSC2006, the TSC2006EVM is installed in the topmost EVM slot, which connects the
TSC2006 digital control interface to the SPI port of the TAS1020B. Because the TSC2006 has no audio
features, the lower EVM slot (which is connected to the TAS1020B digital audio interface) is not used.

As configured from the factory, the board is ready to use with the TSC2006EVM. However, if external SPI
control is desired, the signals may be applied to J15, as long as the SW2 is set to OFF position so that
USB SPI control is disabled. To view all the functions and configuration options available on this board,
see the USB-MODEVM Interface Board schematic in Section 7.2.
6.4
Program Description
After the TSC2006EVM-PDK software installation (described in Section 6.2), evaluation and development
with the TSC2006 can begin.
Running the TSC2006EVM-PDK software on your PC displays the interface GUI as shown in Figure 2. On
the top-left side of the GUI, a lit green LED indicates the digital serial interface type, which should be SPI
for the TSC2006EVM-PDK. The next box shows the location and reversion of the firmware.
The two LEDs on the top right corner of the GUI can be used to reset TSC2006 by software and to stop
the TSC2006's ADC operation. Note that the two LEDs reflect the corresponding bits inside the CB1.
When the SW Reset LED is lit (in blue), the bit 1 of CB1 is set to logic 1 and TSC2006 is in the software
reset mode; when the LED is OFF (in black), the bit 1 is set to logic 0 and TSC2006 is not reset and is in
normal mode. When the Stop ADC LED is lit (in red), the bit 0 of the CB1 is set to logic 1 and TSC2006's
ADC is stopped. When this LED is OFF (in black), the bit 0 is logic 0 and TSC2006 is running in normal
operating mode.
On the top-right side of the GUI, two boxes labeled CB0 and CB1 display the current/default settings of
the TSC2006 control byte mode 0 (CB0) and mode 1 (CB1), respectively. See the TSC2006 data sheet on
the control byte and its two modes.
The data in CB0 is written to TSC2006 while writing to a control register, and CB0 is the common byte.
The data in CB1 is written to TSC2006 while one of the following occurs:
• Bit 0 (STS or Stop ADC) is set by clicking on the LED in left/top corner.
• Bit 1 (SWREST or SW Reset) is set by clicking on the SW Reset LED.
• Bit 2 (RM or Resolution) is set at the Human Interface tab.
• Bits 3 through 6 (Converter Function Select) can be set at this tab beneath the CFR1 section.
The majority evaluation can be implemented using three tabs on the TSC2006EVM GUI: Human Interface,
Configuration, and Command Line Interface. Clicking on a tab accesses the functions corresponding to
the tab. The following discussion details the three tabs.

Human Interface
Start TSC2006 EVM software, the Human Interface tab shows up by default. The three sections on this
tab are shown in Figure 3.
Figure 3. Human Interface Tab
6.4.1.1
Touch Screen Control Function
The touch screen box in this tab is updated when a touch is detected on the touch screen. As the touch
screen is drawn on, the motion on the touch screen is translated into pixels on this box. The software
takes X, Y, Z1, and Z2 readings which are shown to the right of the touch screen box. As the touch
pressure is increased, the pixel size increases; a lighter touch results in thinner pixel sizes.
The Z-value displayed is not totally what is described in the TSC2006 data sheet, because in the data
sheet equations, it is assumed that the resistance of the touch screen being used is known. The value
used in this program is calculated by Equation 1 of the TSC2006 data sheet, but without multiplying it by
the Rx-plate resistance. This value is shown as Z beneath the measured touch data, X, Y, Z1, and Z2; and
normally ranges from 0 to 4, with larger numbers representing a more forceful press on the screen. Using
the Maximum Z Value to Display knob, you can set a threshold so that the program does not display
lightly pressed points. This threshold setting helps to eliminate display of spurious points that may result
from touch screen mechanical bouncing.
The display in the touch screen box can be cleared by pressing the Clear Graph button on the screen.

6.4.1.2
Data Acquisition Functions
The TSC2006 provides for measuring an auxiliary-input voltage and the temperature. A data acquisition
functions on this tab displays the measured values for these parameters. Measurements are updated only
when the touch screen is not being pressed, and the Auto Reading LED is on.
Temperature is displayed using both measurement modes described in the TSC2006 data sheet. Using
the TEMP1 and TEMP2 measurements, a temperature reading with 2°C resolution and accuracy is
achieved. Using only the TEMP1 measurement, a reading with 0.3°C resolution is possible, but requires
knowing the TEMP1 value at 25°C. This normally requests a calibration that the user performs. This
program assumes that TEMP1 = 600 mV at 25°C.
By default, the software continuously reads nontouch data, AUX, TEMP1, and TEMP2 and automatically
updates them in the Non-Touch Data Acquisition section of this tab. To stop the data acquisition, click on
the green LED Auto Reading in the top-right corner.
6.4.1.3
Direct Configuration
In the TSC2006, the parameters or modes of the device can be set up or configured in two ways. One is
to set up the control registers; the other is to write directly to TSC2006 through control bytes. The majority
setups and status of the TSC2006 can be accessed through write/read TSC2006 control registers; also a
couple of parameters/modes can be accessed through the direct configuration, which include Resolution,
ADC Power-Down, ADC Stop, and SW Reset. See the data sheet for more details.
In the Human Interface tab, two direct configuration modes can be accessed: one is resolution; and
another is ADC Power-Down mode.
The TSC2006 ADC can be configured to operate in 10-bit or 12-bit resolution modes, which can be
directly configured using Control Byte Mode #1 or CB1 or by writing to the bit #13 of control register
CFR0. Clicking on the resolution option in this tab changes the resolution setting in CB1. Note that the
CB1 box on the top of the tabs is updated correspondingly while any of its control bits changes. You may
also need to change the resolution setting in CFR0 (which is discussed in the next section on the
Configuration tab) to make them consistent.
A Power-Down bit in TSC2006 Control Byte Mode#0 or CB0 can be set from this tab to power up the ADC
biasing circuitry always, or to power down the power between conversions. The box under the control
button PND0 shows the brief description.
6.4.2
Configuration Tab
On the Configuration tab, shown in Figure 4, all of the TSC2006 control registers can be accessed and
written to.
The tab has four sections, corresponding to the configuration registers CRF0, CFR1, CFR2, and the four
thresholds registers, respectively. Also, two boxes, one under the CFR1 section and the other under the
Threshold Selection section, display the current values writing to these TSC2006 control/configuration
registers.
Note that a digital box is next to each of these multiple selectors; clicking on this box sends the data to the
corresponding control registers.

6.4.2.1
ADC Configuration (CFR0)
This section controls the parameters in CFR0. Each button or selection controls one parameter.
• Pen Control Mode
The button controls if the touch data acquisition is started or initialized by host processor's command
(manually) or by a touch on the screen (automatically). Default by touching screen.
• Stop ADC
This button can stop TSC2006 ADC, or put the ADC to normal running mode. Default to normal
running mode.
• Resolution
Selects between 10- and 12-bit resolution. Note that, the bit #2 of CB1 also controls the resolution and
thus you may need to double-check the settings at both places to make sure they are consistent.
Default setting is 12-bit resolution.
• Conversion Clock
The internal clock which runs the A/D converter can run at 4, 2, or 1 MHz. Note that, when running at 4
MHz, only 10-bit resolution is possible, but 12-bit is not. Thus, you may need to check resolution
setting after selecting 4-MHz conversion clock. By default, the clock is running at 2 MHz.
• Panel Voltage Stabilization Time
This is the time that the TSC2006 allows for the touch screen to settle after turning the drivers on.

Precharge Time
Sense Time
These two parameters are the time allowed to precharge the touch panel capacitance and then sense
to see if the screen is touched. For more details on these parameters, see the TSC2006 data sheet.
Detection of Pen Touch in Wait
This option is valid when the ADC is put into the host-controlled mode. Enabling this option puts the
pen touch detection in the background and allows the TSC2006 to pull its PINTDAV pin high if no pen
touch is detected while waiting for the host to issue a command, so that the host can decide if a
reading touch data command should or should not be issued.
Longer Sample Mode
Enabling this option adds an extra 500 ns of sampling time to the normal sampling cycle. It is disabled
by default.
Test Mode Configuration (CFR1)
TSC2006 features a touch screen test function to check if the 4-wire touch panel had been properly
connected and if there is short-circuitry. To implement the connection test, the resistance range of the
touch screen should be entered into CFR1. Select Short Circuit Panel Test to perform the short-circuitry
test function.
To perform a touch screen test, the Converter Function Selection must be set up in CB1 as X-Axis
Connection Test, Y-Axis Connection Test, or Short-Circuit Test. The multiple selector under CFR1
provides the access.
The test result returns to the STATUS register.
Another TSC2006 feature is the Batch Delay Mode, as shown in the CFR1 section. Under the
TSC-controlled ADC mode, this feature adds delay between ADC samples and thus controls the
time/interval between samples. The batch delay ranges from 0 ms to 100 ms.
6.4.2.3
MAVF Configuration (CFR2)
The preprocessing MAV filter (MAVF) inside TSC2006 reduces sampling noise. See the data sheet for
details of the MAVF.
The CFR2 section has five selection buttons that can be used to enable/disable the MAVF on touch data,
X, Y, and Z, or nontouch data, AUX and Temperature.
Clicking on the MAV Filter Control option box brings up a list of settings on M and W values. Select an
eligible option from the list (do not select the Reserved) and the corresponding digital shows up at the next
box. Clicking on the digital box writes the selected value to the CFR2 register.
6.4.2.4
Threshold Configuration
Zone detection is one of the new features the TSC2006 offers. Zone detection function was designed to
monitor the zone/range of the nontouch inputs, including AUX and TEMP1/TEMP2.
The four control registers inside TSC2006, used to set up the top and bottom thresholds of AUX and
TEMP1/TEMP2, can be accessed through the four moving slides in the Threshold Selection section. The
zone detection modes can be controlled/selected through the two option boxes at the bottom of the CFR2
section.

line of the script is a reading command, the read data is shown at the Read Data section; if the line of the
script is a writing command, the written data bytes also are returned to the Read Data section.
As Figure 6 shows, three read buttons reveal the contents of the threshold, control, and status registers of
the TSC2006, displaying them in the Data Read/Written section of the screen. The data flow shows on the
top and is interpreted and listed correspondingly on the button

Software Script
The TSC2006EVM-PDK software was designed to identify and decipher several scripting commands, as
shown in the Command Type list in Table 6.
Each line in a script file is a command; a line is terminated by a carriage return.

The first character of a line indicates the command type. Table 6 lists all the command types of the
TSC2006EVM-PDK software.
Following the command type w or r, the byte is the I2C device address. For TSC2006, a SPI device,
this address must be always 0x00.
No byte follows a # (comment) or a b (break) command.
The byte or bytes following a command type d is the delay time in milliseconds.
The second byte in a w or r command line is the address of the configuration register. Table 7 provides
the common use address in a w and r command line.

Where the first byte is for 10 bits of resolution and the second byte is for 12 bits.
(2)
Where the two bytes reflect the different ADC bias power modes: if bit#2 =1, ADC bias power ON always; and if bit2=0, it
powered down between converter.
In an r command, the byte after the address indicates the number of registers reading from; and the next
byte is ignored. If more than one register needs to be read, the next byte is the address and is followed by
two dummy bytes that are ignored.
In a w command, the two bytes after the address (see Table 7) are the data writing to the 16-bit TSC2006
registers. If more than one registers needs to be written, the next byte is the address and followed by two
data bytes.
For writing to TSC2006's CB1, this byte includes both address and content and thus there will be no
further byte after this address byte.
Example 1: Writing to CB1 and changing the resolution mode to 10 bit.
w 00 80
Example 2: Writing 0xA924 to CFR0 register and writing to CB0 to set ADC bias power on always.

Down Load Script
To down load an existing script into the Control Buffer, first go into the File menu, and select Open
Command File..., which opens a file-select window and allows you to browse and find a script file. Then,
click on Open and the script is loaded into the command buffer. An example is shown in Figure 7.

Log Script and Data
The software can track and record the script or data used while using the TSC2006EVM GUI. In the File
menu, Log Script and Results ... or Log Data to File ... can be selected to generate the script or data log
file.
6.4.4.1
Log Script and Results
Go into the File menu and select Log Script and Results..., which opens a file-select window and allows
you to specify a log file to which to write the script and results. At this point, the script to read/write and the
results start to be logged into the file. For example, a written script is logged into the file for any action
performed at the Configuration Tab (Section 6.4.2); and a reading script and the reading results are
logged into the file if one of the read buttons on the Command Line Interface Tab (Section 6.4.3) is
clicked.
6.4.4.2
Log Data to File
Go into the File menu and select Log Data to File ..., which opens a file-select window and allows you to
specify a log file to which to write the data. At the same time, this enables the Datalogging menu.
When ready to begin recording data to a file, select Datalogging→Start Logging Data is written to the file
until Datalogging→Stop Logging is selected. When the screen is not touched, the AUX, TEMP1, and
TEMP2 values are written to the file; the X, Y, Z1, and Z2 parameters are written to the file with values of
9999, to indicate that they are not updated. When the screen is touched, the X, Y, Z1, and Z2 parameters
are written while the AUX, TEMP1, and TEMP2 values are written to the file as 9999.
The format of the data file has the first column as the time in milliseconds (which is just a timer in the
program and can arbitrarily start at any number); then X, Y, Z1, Z2, AUX, TEMP1, and TEMP2 columns
follow. Every new reading is a new row in the file.
After Start Logging, the data is constantly updated, and the datalog file can quickly grow large. Therefore,
log only necessary data.

EVALUATION BOARD/KIT IMPORTANT NOTICE
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. Persons handling the
product(s) must have electronics training and observe good engineering practice standards. As such, the goods being provided are
not intended to be complete in terms of required design-, marketing-, and/or manufacturing-related protective considerations,
including product safety and environmental measures typically found in end products that incorporate such semiconductor
components or circuit boards. This evaluation board/kit does not fall within the scope of the European Union directives regarding
electromagnetic compatibility, restricted substances (RoHS), recycling (WEEE), FCC, CE or UL, and therefore may not meet the
technical requirements of these directives or other related directives.
Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30
days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY
SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING
ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all
claims arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to
take any and all appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER
FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of
patents or services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the
product. This notice contains important safety information about temperatures and voltages. For additional information on TI’s
environmental and/or safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 0 V to 3.6 V and the output voltage range of 0 V to 3.6 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 30°C. The EVM is designed to
operate properly with certain components above 85°C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
