1. Product Overview  
1-1. Products Applicable  
This specification is applicable to TSC-34/U-L.  
1-2. Overview  
TSC-34/U-L is a touch screen controller board that performs an A/D conversion of an analog signal of a 4  
wire resistive touch screen, and transmits the coordinate data to the host in a 10-bit resolution via USB  
interface. TSC-34/U-L can be used for various applications for its functions including the power saving  
mode, seven sampling speed settings (max. 150p/s *1), two external switch connections, and automatic  
calibration data loading with an external EEPROM.  
TSC-34/U-L is a succeeding model of the boards of the TSC-10/USB-PI. TSC-34/U-L is lead-free and  
compliant with RoHS.  
§
TSC-34/U-L  
TSC-34/U-L dispenses a need to newly design the peripheral circuits, and can easily  
be used by connecting to the touch screen and the host. Using the driver software *2  
enables the mouse emulation on various operation systems and dispenses the need  
to newly design the controller software.  
TSC-34/U-L is the product compatible with software of the TSC-10/USB-PI.  
*1: 150 transmissions of coordinate data per second.  
*2: Please contact the local sales representatives for software availability.

1-3. Peripheral Composition Overview  
A resistive touch screen is operated by resistance sensitive system between two layers such as film or  
glass. Two pieces of transparent materials with conductive coating are placed in the same direction as  
two electrodes face each other. The touch screen is activated when these transparent conductive layers  
are pressed to contact each other with a finger or a pen. The one of these conductive layers functions as  
an X-coordinates electric circuits and the other as a Y-coordinates circuits.  
To measure the  
X-coordinates TSC-34/U-L supplies voltage, Vcc to the one of X-coordinates electrodes with GND to the  
other. When the touch screen is pressed under this environment the voltage of the X-coordinates resis-  
tance is detected by the Y-coordinates electrode (A_in) at the input point (x1), where the X-Y coordinate  
resistance layers make contact. The detected voltage in supply side is higher than the GND side, which  
means ‘A_in’=Vcc at the point ‘E’ and ‘A_in’=0(*1) at the point ‘A’. TSC-34/U-L calculates coordinates  
data starting from A/D conversion of the ‘A_in’ voltage. The Y-coordinates is measured in the same way.  
By repeating this process alternately, coordinate value at the input point is determined.  
(*1) Excluding the loss in the controller circuits and touch screen. Actual detected voltage should be  
lower than ‘Vcc - GND’ because of loss happened in the circuitry.
